　　Original title: Love the hometown, Guangdong overseas Chinese lead the charity style

　　The amount donated by overseas Chinese, Hong Kong and Macao compatriots in Guangdong accounts for about 70% of the total overseas Chinese donations.

　　editorial comment/note

　　Guangdong is the largest hometown of overseas Chinese in China. Overseas Chinese and compatriots from Hong Kong and Macao, whose ancestral homes are in Guangdong, account for more than two-thirds of the total in China. In 1978, the horn of China’s reform and opening-up sounded, and overseas relations gradually picked up in this strong spring breeze. At the beginning of 1979, Guangdong Province proposed to the central government to establish a special economic zone, which was based on Guangdong’s unique provincial advantages of "being adjacent to Hong Kong, Macao and many overseas Chinese". Since then, in Guangdong, the country’s largest hometown of overseas Chinese, millions of overseas Chinese and compatriots from Hong Kong and Macao have joined hands with their parents, brothers and sisters in their hometown and devoted themselves to realizing the dream of becoming a strong country, becoming witnesses, participants and promoters of these 40 years of changes.

　　General Secretary of the Supreme Leader pointed out that the vast number of overseas Chinese have sincere patriotic feelings, strong economic strength, rich intellectual resources and extensive business contacts, which are important forces for realizing the Chinese dream. At the celebration of the 40th anniversary of the reform and opening up held on December 18th, General Secretary of the Supreme Leader also pointed out that since the reform and opening up, the sense of national identity and cultural identity of all Chinese people at home and abroad has been greatly enhanced, and the will to build the Chinese dream with one heart and one mind has become stronger. On the same day, the CPC Central Committee commended a number of outstanding contributors to the reform and opening up, including Hong Kong and Macao patriots Henry Fok, Ma Wanqi and Ceng Xianzi. They are outstanding figures who have made great contributions to the development of Guangdong.

　　For months, Nanfang Daily has sent an interview team to the United States, Thailand, Malaysia, Spain, Panama, Dominica and other countries and Hong Kong and Macao. From now on, it will launch a series of reports on "Guangdong overseas Chinese as a bridge connecting the four seas" to show the great contributions made by overseas Chinese and compatriots in Hong Kong and Macao to China’s reform and opening up. Please pay attention.

　　Not long ago, Mr. Huo Zongjie, the leader of overseas Chinese in Canada, donated an ambulance to the town health center in Xinyi City, our province. The 87-year-old man walked in underdeveloped areas of China, especially Guangdong, donating schools and hospitals, which led to charitable donations of 240 million yuan. He is one of the representatives of thousands of overseas Chinese and compatriots in Hong Kong and Macao who love their country and their hometown and are enthusiastic about public welfare.

　　As early as October 1977, Deng Xiaoping, the chief architect of reform and opening up, pointed out that overseas relations "are a good thing." The "overseas relations" mentioned here refer to tens of millions of overseas Chinese and compatriots in Hong Kong and Macao, and the energy they release is enormous.

　　Since the reform and opening up, overseas Chinese, Hong Kong and Macao folks have worked with the people of our province with one heart and one mind to realize the dream of strengthening the country. In our province alone, donations from overseas Chinese and compatriots from Hong Kong and Macao account for about 70% of the total donations from overseas Chinese.

　　Policy spring breeze warms the hearts of overseas Chinese

　　Before the reform and opening up, some overseas Chinese and compatriots from Hong Kong and Macao had their houses and ancestral halls confiscated. With the adjustment of overseas Chinese policy, the negative effects were gradually eliminated, and the cold hearts of overseas villagers gradually recovered and set foot on their hometown land again.

　　There are many overseas folks in Xiaolan Town, Zhongshan, but not many returned home in the early days of reform and opening up. To this end, the town restarted the 800-year-old Chrysanthemum Festival, using flowers as a medium to contact the nostalgia, so that overseas folks can see the new atmosphere in their hometown. In November, 1979, the fragrance of flowers and the nostalgia returned, and 150,000 people flooded into the town. The Hong Kong Zhongshan Xiaolan Association, which has been alienated from its hometown for more than 30 years, has joined the ranks of relatives and friends in the sound of gongs and drums. Since then, the Hometown Association has become the best "hometown propagandist", driving the donation of hospitals, schools and tap water projects.

　　侨房是侨情畅通的重要渠门。广东省侨办原主任杨山说：侨房的一草一木一砖一木，都维系着港澳同胞对家乡的爱。当时，广东亟待清退的侨房数目巨大，要解决的话涉及各种复杂问题，还包括天文数字的安置费。然而，侨房一日不退，侨心一日难归。在党中央的关心和拨款支持下，我省各地行动了起来。

　　位于广州的永安堂，是东南亚著名侨领胡文虎的物业。1992年7月，广东省决定向其后人发还这座珠江边的大厦。胡文虎长女胡仙深受鼓舞，同年以香港星岛日报掌门人的身份率团访京，受到时任中共中央总书记江泽民的接见。感念于此，她后来放弃了可观的商业发展价值，将收回的永安堂捐赠给广州市政府，改建为少年儿童图书馆。

　　数据显示，我省用于落实侨房政策的专款达8亿多元，清退处理的城乡侨房近3000万平方米，全面解决侨房历史遗留问题。这大大鼓舞了海外和港澳的广东人，带来了捐赠和投资剧增的效应。

　　Donations from "Charcoal givers" keep coming.

　　Tian Jiabing, a 99-year-old Hong Kong philanthropist, passed away on July 10th this year. The person who donated the most schools in mainland China once said in an interview with Nanfang Daily: "I like to be a’ charcoal giver’ most, and giving charcoal in the snow for education is the greatest satisfaction in life." He sold the building and factory building where he lived, and donated many schools, kindergartens and rural school libraries in the mainland …

　　In Guangdong, overseas Chinese and compatriots from Hong Kong and Macao from more than 100 countries and regions donated more than 45,000 public welfare and transportation projects. Among them, the construction and expansion of schools account for more than half of the total in the province, which not only improves the educational conditions in our province, but also creates a social atmosphere of respecting education. Especially in the early days of reform and opening up, when Guangdong’s education, medical care, culture, transportation and other facilities were backward, these donations were just a timely help. Henry Fok, Li Ka-shing, Huang Qiu, Ceng Xianzi, Fang Runhua, Huo Zongjie … are all such "gifts".

　　These benevolent people include billionaires, white-collar workers and wage earners: Tang Furong, an old man from Macao, lives in a humble room of 60 square meters, but contributes to hundreds of public welfare projects in Guangdong and other places. Mr. Wu Guixian, an overseas Chinese in Japan who is committed to subsidizing education, actually sold his own house when he encountered financial difficulties in donating money. He donated more than 50 million Hong Kong dollars to support primary and secondary schools in his hometown of Zhongshan, as well as Sun Yat-sen University, Jinan University and "Hope Primary School" inside and outside the province. Wu Guixian’s wife said: "He knew I wouldn’t object and donated all the money for selling the house, leaving no money."

　　Leading the new atmosphere of respecting morality and education

　　The project to unite the hearts of overseas Chinese has brought new fashion to Guangdong, with the continuous development of charity culture and the formation of a good social atmosphere of respecting morality and education. Overseas Chinese, compatriots from Hong Kong, Macao and even the people of the whole province, all with one heart and one mind, benefit and support their hometown development, and enhance the cohesion of villagers at home and abroad.

　　Wuyi University, located in Jiangmen, the hometown of overseas Chinese, was jointly initiated by Lv Zhihe, Sir Quo wei Lee, Huang Qiu and other overseas Chinese and compatriots from Hong Kong and Macao in the 1980s, and was built with a donation of HK$ 230 million from thousands of good-natured benevolent Weng. It was the education project with the largest number of people participating in the construction at that time in our province.

　　Shantou University donated more than HK$ 6.6 billion by the Li Ka-shing Foundation, making it the only public university in China funded by private foundations. In June this year, 90-year-old Mr. Li Ka-shing attended the graduation ceremony of Shantou University and handed over the honorary chairmanship of the school board to his son. In an interview with Nanfang Daily reporter, he said: "I have persistently donated to build Shantou University, and I firmly believe that’ knowledge changes fate’ and I want to help the younger generation in China develop."

　　Many donations are far more meaningful than the project itself. The Luoxi Bridge donated by Mr. Fok Ying-tung has brought prosperity to the southern part of Guangzhou and promoted the great development of Guangdong’s transportation network. Dr. Huang Zhaoqiang from Australia led a Chinese medical team, bringing equipment, medicines and intraocular lenses with him, to remove the biggest obstacle to poverty alleviation for countless poor cataract patients; Xu Xiangling, a retired social worker from Hong Kong, went to Dongguan to set up the first service center for migrant workers in our province, raised funds to support more than 1,300 children of migrant workers to return to the classroom, and also organized six cultural tutorial schools for children of Xinwan people. Lenian Liao, a retired Malaysian teacher, has been raising funds everywhere for more than ten years, and has volunteered to teach English in Tai Po, which has broadened the life path for children in mountainous areas and inspired volunteers from Guangdong and Hong Kong to participate in teaching …

　　In the 40 years of reform and opening up, Guangdong’s economy and society have developed rapidly, and the people’s lives are getting better and better, thanks to the strengths of overseas Chinese in our province, who are all over the world. Overseas Chinese, Hong Kong and Macao compatriots’ feelings of home and country and their charitable effects shine brightly on the land of Guangdong.

　　-Interview

　　All roads lead to the same goal, Aiguo Road

　　On October 19th this year, a groundbreaking ceremony was held in Chen Weinan Cultural Center, Chaozhou City, Guangdong Province. Chen Weinan, a 99-year-old Hong Kong industrialist, attended the groundbreaking ceremony with his family. This is one of the countless public welfare projects he has donated for decades.

　　Chen Weinan and Chen Younan, the father and son, one is devoted to donating money to public welfare projects in their hometown, and the other is devoted to promoting the development of science and education in the whole province, especially in eastern Guangdong. They are doing different things. Similarly, they are all contributing to enhancing the international influence of Chinese culture and Chaozhou culture and accelerating economic and social development. A few days ago, Nanfang Daily reporter interviewed the father and son in Hong Kong and listened to them talk about the patriotic road that leads to the same goal.

　　Chen Weinan: The country should strengthen education first.

　　Chen Weinan was born in Chao ‘an County, Guangdong Province in 1919. He experienced domestic troubles and foreign invasion, and was invaded by the Japanese army. Even his ancestral home was occupied by the Japanese army. In 1937, Chen Weinan, then 18 years old, went to Hong Kong to make a living and worked hard to build a solid enterprise foundation. But he always has a strong feeling of home and country: the country is not strong, and the people can hardly say happiness and dignity.

　　After leaving his hometown for decades, in 1984, Chen Weinan was invited to return to Chaoshan. He is gratified by the new atmosphere of reform and opening up, but he is also heartbroken by the educational situation in his hometown. The old ancestral temple, which was blown to pieces by the Japanese army, is still used as a primary school classroom, with poor lighting and no fan. He thought it was time to give back to Mulberry, so he donated a modern primary school covering an area of 12 acres in the local area, and later invested more than 60 million yuan to donate a Baoshan Middle School covering an area of 130 acres, with 4,000 students.

　　Since then, Chen Weinan’s road of selfless help has gone further and further, extending from his hometown in Chaoshan to many places in Guangdong and China. He is engaged in charitable donation and sets himself the principle of "three noes": donate voluntarily without waiting for it; Do not want to leave a name, do practical things again; No demands, selfless dedication.

　　The venerable old man said, "I can contribute to the society as much as I can, which is the blessing of my life and the greatest value." Up to now, Chen Weinan has donated more than 150 million yuan, of which 80% is invested in education. Because he firmly believes that if the country is strong, education will be strong first.

　　Chen Weinan is very pleased that the motherland is becoming stronger and stronger and plays an important role in the world. He often encourages young people: "For Chinese who are struggling all over the world, the strength of the country is a strong backing for everyone’s development. Therefore, everyone should contribute wisdom and strength to the country, especially to the development of Guangdong, Hong Kong and Macao. "

　　He was the founding president of the Association of Hong Kong Members of the Third CPPCC Chaoshan Committee and the founding president of the Guangzhou Chamber of Commerce for Foreign Investment, and founded the Hong Kong Association of Chaozhou Associations. In 2000, Chen Weinan was awarded the bronze bauhinia star by the Hong Kong government, which was highly praised by this philanthropist.

　　Chen Younan: Building an Innovation Platform for Overseas Chinese, Hong Kong and Macao Students

　　Chen Younan is a Ph.D. student in chemical engineering in the United States and Canada. Inspired by his father, he returned to Hong Kong to develop, and also joined the ranks of boosting the construction of the country and hometown. Although he shared the same feelings with his father, he paid more attention to uniting the younger generation of overseas Chinese and Hong Kong and Macao folks and became a force for China’s scientific and technological innovation and development.

　　In 1998, Chen Younan founded the International Youth Friendship Annual Meeting to unite the outstanding youth in the world. In 2012, he took over as the chairman of the Hong Kong Chaozhou Association and became the head of the largest Chaozhou Youth League organization in Hong Kong. Up to now, the association has 41 group members, with more than 150,000 members. This year, Chen Younan was awarded the silver bauhinia star by the Hong Kong government. He initiated the general meeting to hold "Chaozhou Festival", "Yulan Victory Club" and other activities, so that the younger generation can deepen their perceptual knowledge of their hometown culture, which is very popular.

　　In 2013, Chen Younan founded the "International Tide Doctor Association" (hereinafter referred to as "Tide Expo"), which brought together more than 2,000 experts and scholars at home and abroad with doctoral degrees or above in five years. This is not only a network for professional hipsters to contact the rural situation, but also a think tank to promote the development of Guangdong. They held a doctoral forum for four consecutive years, focusing on topics such as food and medicine, the Internet, the new economy, and the smart future, and invited the world’s top academics to give speeches and participate.

　　Chen Younan, who is as concerned about the development of education as his father, said: "According to the strategic layout of Guangdong Province for the development of eastern Guangdong, more high-end talents are needed here. Therefore, the Chaobo Fair has initiated the establishment of Chaoshan University since two years ago, and has received positive responses from Chaozhou people at home and abroad and hometown leaders. "

　　Chen Younan has actively traveled to mainland and overseas universities to contact experts, scholars and entrepreneurs, and has raised 10 million yuan as the start-up fund. He told reporters that he would first set up an advanced research institute corresponding to industrial development, and conduct research in four directions: new materials and engineering science, bioengineering and life science, intelligent engineering and control science, environmental engineering and earth science.

　　Housing accumulation fund is a special fund to solve the housing problem of employees. However, in reality, for various reasons, the use of provident fund loans for housing purchases often encounters problems. A few days ago, the Ministry of Housing and Urban-Rural Development, the Ministry of Finance, the People’s Bank of China and the Ministry of Land and Resources jointly issued the Notice on Safeguarding the Rights and Interests of Housing Provident Fund Deposited into Employees’ Housing Loans (hereinafter referred to as the Notice), which regulated the business acceptance period of the housing provident fund management center, the assessment of entrusted banks, and the behavior of developers to restrict housing provident fund loans.

　　Last week, a survey of 2010 respondents conducted by the Social Investigation Center of China Youth Newspaper showed that 46.1% of the respondents had been blocked by provident fund loans to buy a house, and 55.8% of the respondents pointed out that second-hand housing owners often refused to accept provident fund loans or portfolio loans because of the long approval time of provident fund. 92.5% of the interviewees expect their places to implement the Notice as soon as possible, and 67.6% of the interviewees believe that the new provident fund loan policy will enable employees to truly enjoy the preferential purchase of houses.

　　Among the respondents, 66.9% have occupied their own houses, 22.1% are buying them, and 11.0% have not occupied their own houses. Respondents living in first-tier cities accounted for 30.6%, second-tier cities accounted for 44.9%, third-and fourth-tier cities accounted for 18.8%, towns and counties accounted for 4.5%, and rural areas accounted for 1.2%.

　　55.8% of the respondents pointed out that second-hand house owners often refused to accept provident fund loans because of the long approval period.

　　"The interest rate of provident fund loans is much lower than that of commercial loans, but the application process is long, and some are as long as half a year." Liu Yang (a pseudonym), 30, is a staff member of Shenyang Municipal Government in Liaoning Province. Six years ago, he bought a new house with a provident fund loan. It took him three or four months to apply for a provident fund loan, and the procedures often could not be completed at one time, so he had to make several trips. "Sometimes I need to go through the next procedure with the approved results, and the processing time is limited. Our family is very anxious and urged for a long time, and finally some things are delayed."

　　Wang Yuan, a resident of a town in Tangshan, Hebei Province, just bought a newly opened residential house in full a few days ago. "The developer directly indicated that he only accepts full customers without any discussion. It is also said that the next phase of the new real estate is also sold in this way, and the price may double. I want to buy it as soon as possible. "

　　According to the survey, 78.4% of the respondents found that the use of provident fund loans to buy a house was generally blocked, and 22.4% of the respondents bluntly said it was very common. 46.1% of the respondents have been blocked by provident fund loans to buy a house, 46.8% of the existing housing groups have encountered this situation, and 58.2% are buying a house.

　　Liao Beibei (pseudonym), who worked in Beijing for two years, bought a stock house at the end of 2017. She recalled that in more than an hour after signing the contract, the intermediary did not ask her which loan method to choose, and directly defaulted to pure commercial loans. "At that time, there were so many things that I forgot to use the provident fund loan. Later, when asked about the intermediary, he said that the house I bought was on the high side, and I could only borrow for 7 years by using the provident fund loan. "

　　The survey shows that the most common situation when buying a house with provident fund loans is that second-hand house owners do not accept provident fund loans or portfolio loans because of the long approval period of provident fund (55.8%). Others include: second-hand house owners cannot use provident fund loans because of the age limit of second-hand houses, or the loanable period is short (44.8%), developers stipulate that commercial loans are preferred or discounted (44.6%), developers do not accept provident fund loans to buy a house (35.9%), and second-hand house owners directly indicate that commercial loan customers are given priority.

　　Jiang Tao (pseudonym), a broker in a certain district of a national chain housing agency in Beijing, revealed that the proportion of customers who use provident fund loans is lower than that who use commercial loans. First, it takes a long time to go through the formalities of provident fund loans, and owners generally hope to collect money as soon as possible. At the same price, owners usually prefer full-payment customers, followed by commercial loan customers, and finally provident fund loan customers, and customers need to increase their prices to enhance their advantages. Second, the current maximum amount of provident fund loans in Beijing is 1.2 million yuan, and the low monthly deposit may not reach this level, which requires customers to increase the down payment. In addition, the buildings with long building age and brick-concrete structure also affect the use of provident fund loans to some extent. "It is not uncommon for new real estate developers to require a down payment of more than 50%. Some developers will give customers corresponding discounts according to the amount of down payment in order to get the funds back as soon as possible."

　　Professor Yi Cong, deputy dean of the School of Economics of Tianjin University of Finance and Economics, pointed out that there are two main reasons for the low efficiency of the use of provident fund at present: first, the approval period of provident fund loans is really too long, the approval procedures are complicated, and the restrictions on purchases and loans will also lengthen the approval time. Second, affected by the long approval time, developers will put provident fund loan customers behind and treat different consumers differently. This is an act of infringing on consumers’ rights and interests.

　　67.6% of the respondents believe that the new provident fund loan policy will enable employees to truly enjoy the preferential purchase of houses.

　　"I have seen dozens of houses before and after last year, and I often encounter the situation that the owners only consider the full amount and commercial loan customers." Cheng Xiao (pseudonym), an employee of a foreign company in Beijing, lamented, "After all, there are only a few people who can buy a house in full in Beijing, and the commercial loan interest rate is high, which makes the ordinary working class very difficult."

　　Cheng Xiao noted that the Notice requires the housing provident fund management center and the entrusted bank to standardize the loan business process, and the examination and approval work will be completed within 10 working days from the date of accepting the loan application. She believes that this move has solved the most critical problem of blocked provident fund loans. "In the future, the procedures for provident fund loans will even be faster than commercial loans, and working-class people can really enjoy the benefits of buying a house."

　　Wang Yuan said that the "Notice" provides a channel for the masses to report discrimination against provident fund loan customers, which is thoughtful and comprehensive.

　　According to the survey, 92.5% of the respondents are looking forward to the implementation of the Notice as soon as possible, and 42.1% of the respondents expressed great expectation. 67.6% of the respondents believe that the new provident fund loan policy will enable employees to truly enjoy the preferential treatment of buying houses, 57.4% of the respondents believe that the provident fund loan channel will be effectively guaranteed, 53.8% of the respondents believe that the new policy can effectively crack down on developers who suppress provident fund loan groups in disguise, and 34.6% of the respondents believe that the new policy can greatly shorten the processing period of provident fund loan procedures and provide convenience for employees to buy houses.

　　To make the Notice effective, Yi Cong pointed out: "First, the detailed implementation rules are the guarantee for the implementation of the policy. Around the housing provident fund management center must be around the "notice" as soon as possible to introduce the implementation details, really improve the efficiency of provident fund loans. Second, strictly implement the spirit of the Notice and come up with reasonable market supervision measures. As the supervision department of the housing market, the Housing Authority should supervise all discriminatory behaviors of developers and accept and handle consumer complaints in a timely manner. "

　　Yi Cong told reporters that the problem of low utilization rate of provident fund loans has been raised by the government and academic circles for many years, and the traditional provident fund management methods and systems should indeed be improved. "The future provident fund system should be reformed in a more market-oriented direction. Like Germany, the provident fund can be gradually moved to a policy-oriented special savings bank. China now has Sino-German Housing Savings Bank, which is a more market-oriented housing policy savings bank. In the future, it is necessary to gradually improve the efficiency of the use of the provident fund and safeguard the rights and interests of consumers in order for it to play its due role. "

　　Liu Yang hopes that all localities will really shorten the processing time of provident fund loans. "The staff of relevant departments should improve their work efficiency, and the service windows should be set as centrally as possible. It is best to explain clearly the procedures and processes needed for handling provident fund loans through language or words, so that buyers can run less errands." (Reporter Du Yuanchun, Zhang Ruobai)

Five minutes, 210 kilometers. This is the recharge level of "S4 Super Fast Charge" released by Xpeng Motors on August 15th.

This is good news for Tucki car owners and users who plan to buy Tucki, and it also marks that the electric vehicle industry has taken another step towards eliminating endurance anxiety.

However, it has never been the style of the new forces to talk about things in a straightforward way. Without a few obscene words, it is not enough to attract the attention of the industry, and it is difficult to express their determination to try to subvert the industry without a few flag. Therefore, Tucki gave a "formula" at the press conference: ultra-fast charging+high battery life+self-charging = eliminating hybrid.

Hearing this rhetoric, the scientific and technological circles cheered and the automobile industry frowned.

The former cheered because the "five minutes of charging and two hours of talking" on the mobile phone can finally be arranged on the car, which is known as the industrial pearl, but the technical threshold is just that. The latter frown because they have seen too many words such as "800V high voltage platform", "overcharge" and "x minutes x 100 kilometers". It is reasonable to say that according to the efficiency of "improvement every six months and iteration every year", charging anxiety should have ceased to exist. But the fact is that people’s charging experience has not ushered in a leap.

Charging is difficult and cannot be solved in the short term.

Compared with the perfect situation of "charging for 5 minutes and cruising for 200 kilometers", the current car owners encounter more scenes of "charging for 1 hour and queuing for 4 hours". Although this is an extreme situation during the holidays, isn’t the significance of the existence of the charging network "to raise troops for a thousand days and use them for a while"? If we don’t solve the pain points of these "edge scenes", isn’t it equivalent to the fact that autopilot can’t identify the "ghost probe"? Breaking the chain at a critical moment is the root cause of people’s distrust of a technology.

In fact, the information that the enterprise thinks the user’s car status is different from that before the actual user’s car status, which is also one of the reasons for the poor user experience. According to Tucki, after investigation, they found that the battery life of pure electric vehicles is generally 500 kilometers. Without home charging, pure electric vehicles can commute for more than one week at a time.

However, according to Analysys "Research Report on the Development of Public Charging Service Market for Electric Vehicles in China in 2022", it is pointed out that the construction of public charging infrastructure network in China is structurally insufficient. And the current charging pile users present three characteristics: more than half of users choose public parking lots for charging; The charging time of users is mostly 0.5-1 hour, and the proportion of users who charge once a day is the highest; Problems such as difficulty in finding piles, long queue time and high charging price affect the charging experience of users.

We basically need to charge every day, but there is no fixed parking space to install electric piles at home, so we have to go outside to find public piles, and the experience of finding piles is still not good.

There is obviously a gap between Tucki’s optimistic expectation of pure trams and the actual experience of users of pure electric vehicles.

On the other hand, according to the actual measurement of several new forces’ overcharged piles in car home, it is found that although the power of some charging piles is as high as several hundred kilowatts, the vehicles themselves do not support such high charging power, that is to say, the bottleneck sometimes lies not in the piles, but in the vehicles. He Xiaopeng also pointed out in the press conference that the current G9 in Tucki and the new models after that can support the S3 and S4 levels of fast charging in Tucki, but "at present, it is impossible to upgrade the previous car to ultra-fast charging, mainly due to the battery limitation, but our S4 super-charged pile will be compatible with S2 and S3 models, which actually improves the charging experience of the previous models". That means, the old models can be charged on the S4 charging pile, but only the charging efficiency of S2-anyway, our technology is changing with each passing day, so you should buy early and enjoy early, but don’t complain about the old technology.

Let’s look at another item in Tucki’s formula, self-operated charging pile. At present, 1,000 self-operated charging stations have been built in Tucki. According to the data of charging alliance, it is estimated that there are 4,015 fast-charging piles and 502 AC piles in Tucki. According to the plan, it is expected to reach 3000 seats in 2025. In contrast, Tesla currently has 1,200 super charging stations in China, with 8,700 piles.

But it seems that Tesla has never shouted the slogan of "eliminating mixing".

Pure electricity may be the end, but it should also be based on the present.

Judging from the current human cognition, pure electricity seems to be the ultimate form of automobile energy transformation, but it is not in "years" as the unit, at least in "years" as the unit.

However, in Tucki’s view, at present, pure electric vehicles can commute for more than a week with one charge, while hybrid vehicles need to be recharged with pure electricity for about 2 to 3 times a week. Refueling will bring higher use cost, and the NVH performance and performance under the condition of feeding are poor.

At first glance, it makes sense, but under the fine product, the flexibility of hybrid cars that can be recharged with oil and electricity has become what He Xiaopeng called "need to be recharged more frequently than pure electricity"-can’t it be refueled? The dual power advantage of oil and electricity becomes "weak power in the state of power loss"-then you can’t move without electricity. The combination is to compare the strengths of pure electric vehicles with the weaknesses of hybrid vehicles one by one, showing that the latter is useless, which can be called the Tucki version of "Tian Ji Horse Racing".

As far as the current market is concerned, the more reasonable process is that before the electric replaces the hybrid, the hybrid first replaces the pure fuel vehicle. According to the Technical Roadmap 2.0 of Energy-saving and New Energy Vehicles of China Automotive Engineering Society, the total proportion of hybrid vehicles (including energy-saving vehicles, PHEV and EREV) in future new energy vehicles will increase from 2.5% in 2020 to 42% in 2025 and reach 52.5% in 2035. Professional organizations have said that in 2035, hybrid vehicles will account for more than half of the total number of new energy vehicles, which is not so easy to eliminate.

TF Securities pointed out in the report "Smart Electric Vehicle Track Depth VI: Hybrid Power Helps the Rise of Independent Brands" that the penetration rate of hybrid vehicles has been greatly improved in 2021. With the launch of a new generation of hybrid products from independent brands, new forces and technology companies, it is expected that the penetration rate of hybrid vehicles will continue to increase rapidly in 2022. According to its calculation, hybrid vehicles may have more than 16 times growth space in 2020-2025.

Different from the traditional European manufacturers adopting P2+48V light mixing and the HEV route adopted by Japanese manufacturers, the domestic independent brands of Great Wall Lemon DHT, BYD DM-i/DM-p, Geely Raytheon and other technologies can almost guarantee the characteristics of strong performance, low fuel consumption and smoothness under any working conditions, which has a solid advantage over overseas technical routes.

However, Cui Dongshu, secretary general of the Federation, affirmed Tucki’s point of view. He pointed out that fast charging and long battery life are definitely no problem. Hybrid is actually just a "spare tire". If the fast charging technology is solved, the "spare tire" is not needed. He said that the hybrid system equipment is too complicated and consumes a lot of energy when using electricity, so pure electricity will be the core trend. However, he also believes that "in the short term, we have to look at technological breakthroughs."

Zhang Xiang, Dean of New Energy Automobile Technology Research Institute of Jiangxi New Energy Technology Vocational College, gave a similar view. With the decrease of power battery cost and the cancellation of subsidies/green licensing policies for PHEV and HEV in various places (starting from January 1, 2023, Shanghai cancelled the issuance of green licenses for PHEV), such transitional technologies will be gradually eliminated. "At present, hybrid vehicles can replace the cost of some expensive power batteries with mature engine technology, but the battery cost will be lower and lower. And the hybrid car has two systems, which are highly complex and prone to problems. In the future, when the battery cost is lower than the engine, it is the time when hybrid technology is eliminated. However, he also pointed out that mixing is not "killed by Tucki", but a general trend in the industry.

It must be admitted that the battery cost will drop, the charging efficiency will be closer to the refueling speed, and electric vehicles will gradually replace fuel and even hybrid vehicles. But no one knows who is still alive and who has been eliminated when this day comes.

　　In 2018, China’s automobile production and sales reached 27.809 million and 28.081 million respectively, ranking first in the world for 10 consecutive years. Faced with such a huge production and sales volume, from June 1 this year, the Measures for the Administration of Recycling Scrap Motor Vehicles (hereinafter referred to as the Measures for the Administration of Recycling) will be officially implemented.

　　According to the new regulations, where will consumers’ old "cars" go, and what impact will this bring to the automobile recycling and dismantling industry? How to "turn waste into treasure" of scrapped cars, realize maximum resource utilization and avoid environmental pollution?

　　The climax of automobile scrapping in China is coming soon.

　　According to the data of the Ministry of Commerce, in 2018, the number of motor vehicles recycled in China was 1.991 million, a year-on-year increase of 14.3%. According to vehicle types, the number of buses recovered was 1.184 million, up 10.5% year-on-year; 381,000 trucks, up 16.4% year-on-year; There were 42,000 trailers, a year-on-year increase of 44%. Among them, the growth rate of trucks and trailers is obvious, mainly because many local governments in China have formulated the target of early elimination and renewal of operating diesel trucks and the implementation plan of subsidies, with the maximum subsidy reaching 100,000 yuan.

　　"Although the number of scrapped cars in China has continued to grow in the past two years, in fact, the climax of scrapped cars in China has not yet arrived." Professor Du Huanzheng, director of the Institute of Circular Economy of Tongji University, said in an exclusive interview with the reporter of Science and Technology Daily that at present, the used car market in China is relatively hot, most of which are used cars eliminated from big cities, and they have not entered the dismantling market when they are sold to small and medium-sized cities.

　　By 2018, there are nearly 730 qualified enterprises for recycling and dismantling scrapped vehicles in China, with more than 2,300 recycling outlets, covering more than 80% of cities and counties in China. Because it is "sold by the catty" as scrap metal, the value of a scrapped car is no more than that of 1000 yuan — 2000 yuan

　　Du Huanzheng said that in 2001, in the "Management Measures for Scrap Vehicle Maneuvering" issued by the State Council, the scrap vehicle recycling industry was recognized as a "special industry", and almost every city above prefecture level had scrap vehicle dismantling points. Because the number of scrap vehicles was less than expected, large-scale dismantling could not be formed. In order to reduce the cost, most scrap points are dismantled manually in the open air, which is inefficient and easy to produce secondary pollution.

　　According to statistics, at present, China’s automobile scrapping and dismantling rate is still low, and the average scrapping rate is only 3% of the ownership & mdash; 4% or so, significantly lower than 6% in developed countries & mdash; 7% scrap rate; China’s recycling and dismantling rate is only 1% of its possession & mdash; 1.5%, far lower than 5% in developed countries & mdash; 6% level.

　　Zhang Ying, secretary-general of the Scrap Vehicle Branch of China Renewable Resources Recycling Association, said: "According to the growth law of domestic car ownership and the law of scrapping years, China’s scrapped motor vehicles will usher in a period of rapid growth around 2020." If the cumulative sales of passenger cars nationwide in 2018 is 22.351 million, according to the international new car sales account for 70% of scrapped cars & mdash; 80%, China’s old car elimination data will exceed 10 million in 2019, and the recycling and dismantling rate and dismantling scale will also increase and expand.

　　Five assemblies and other parts are buried with gold and silver.

　　Engine, steering gear, transmission, front and rear axles and frame are called the "five major assemblies" of automobiles, and they are also valuable parts in automobiles. Du Huanzheng said that according to the previous regulations, the "five major assemblies" of scrap cars with high added value can only be handed over to metallurgical enterprises as scrap steel and melted into raw materials. Therefore, the added value of scrapped cars is greatly reduced, and some car owners are unwilling to trade to formal dismantling enterprises at this low price, and the willingness to invest in society is also reduced.

　　Hu Jianping, deputy inspector of the Market Construction Department of the Ministry of Commerce, said that 18 years ago, the State Council urgently issued the "Management Measures for the Maneuvering of Scrap Cars" mainly in view of the fact that there were many assembled cars on the road at that time and the safety situation appeared. With the development of China’s economy, the phenomenon of assembling cars has gradually decreased. "The problem of assembling cars is no longer prominent, there are more and more private cars, and the car condition is getting better and better. It is urgent to revise the previous management measures."

　　It is a major breakthrough in the New Deal to allow the "five major assemblies" of scrapped cars to be reused. The "Measures for the Administration of Recycling" stipulates that if the "five major assemblies" of dismantled scrapped motor vehicles meet the conditions for remanufacturing, they can be sold to enterprises with remanufacturing capacity in accordance with relevant state regulations and recycled after remanufacturing; Parts other than the "Five Assemblies" can be sold if they meet the mandatory national standards for protecting personal and property safety and can continue to be used, but they should be marked as "Reusable Parts of Scrapped Motor Vehicles".

　　Du Huanzheng said that in order to make scrapped cars "turn waste into treasure", it is necessary not only to allow the "five major assemblies" of scrapped cars to be reused, but also to establish a recycling information system throughout the country, so that recycling enterprises can truthfully record the number, model and flow direction of major components such as the "five major assemblies" and upload them to the recycling information system. "For example, if the transmission of this car is broken, it can be deployed to a suitable remanufactured or reused transmission through the information system, which not only reduces the maintenance cost, but also saves resources." In addition, we should also do a good job in tracing the source, so that the source can be traced and the destination can be traced, and the market order can be strengthened to effectively prevent scrapped automobile parts from flowing into the black market.

　　"At present, the technology in the field of dismantling, remanufacturing and recycling of scrapped cars has basically matured, and some enterprises in China can also produce large-scale mechanical dismantling and automatic sorting equipment used in Europe, America, Japan and other countries; New materials and technologies such as nano are also constantly being introduced. " Du Huanzheng said, however, the basis for using these mature technologies and equipment is large-scale production.

　　Therefore, the Measures for the Administration of Recycling stipulates that enterprises that have obtained the qualification for recycling scrapped motor vehicles have storage and dismantling sites, dismantling equipment and facilities and dismantling operation specifications that meet the requirements of relevant laws, regulations and mandatory standards such as environmental protection, and have professional and technical personnel suitable for dismantling scrapped motor vehicles. And explicitly canceled the "special industry" restrictions, and those who meet the conditions can engage in recycling and dismantling. After the opening of the industry, "it is conducive to attracting social capital into enterprises with advanced technology and large scale, which will accelerate the cultivation of leading enterprises and promote the utilization of new technologies." Du Huanzheng said.

　　The recycling market is as high as tens of billions of yuan.

　　At present, the number of cars in China is 240 million, according to the international 4%— The average level of 6% scrapping ratio, China’s automobile scrapping scale is quite large. Essence Securities pointed out that according to the "five major assemblies" of a car, the recycling value is 5,000 yuan — At present, China’s scrap car recycling market is as high as 60 billion yuan — 84 billion yuan.

　　Experts in the industry said that the current market environment and related policies are conducive to the reuse of the value of scrapped cars, and at the same time help to mobilize the enthusiasm of car owners to scrap and promote new car consumption. Li Yuke, deputy director of the Automotive Industry Policy Research Office of China Automotive Technology and Research Center, said that it is estimated that the sales scale of spare parts will reach 10 billion yuan in the next few years.

　　"The dismantling of scrapped cars is basically physical, and there are fewer pollution links, such as harmless treatment of engine oil, freon, airbags and crushed waste." Du Huanzheng said that in Japan and other countries, the handling costs of freon and airbags are mainly borne by the owners. In China, the extended producer responsibility system can be used to allow automobile manufacturers to pay this fee to dismantling enterprises, thus accelerating the development of the recycling industry of scrapped automobiles, which will also play an important role in China’s motor vehicle industry chain.

　　advice from others

　　There is a relatively complete scrapping and recycling system in big automobile countries.

　　The data shows that countries and regions with developed automobile industry have also developed the recycling and processing industry of scrapped cars, with a relatively sound system. There are 5,000 scrap car recycling and dismantling enterprises and 140 crushing enterprises in Japan, and the recycling rate of scrap cars is close to 100%. In 2005, the Automobile Recycling Law was promulgated, which clearly stipulated the division of responsibilities between automobile manufacturers and those responsible for dismantling and crushing enterprises. Through the automobile registration and declaration system and recycling system, we can master the export of each used car, the flow of used cars and the dismantling of used cars.

　　The United States stipulates that car owners can’t throw away used motor vehicles at will, and there is also a relatively complete motor vehicle scrapping and recycling system. There are about 12,000 scrap car recycling and dismantling enterprises, about 200 car crushing enterprises and 20,000 parts remanufacturing enterprises in the United States. Most of the dismantling and recycling enterprises and automobile manufacturing enterprises are jointly operated. Automobile manufacturing enterprises have the obligation and responsibility to undertake scrap car recycling, and have professional remanufacturing and parts refurbishment technology, which can remanufacture engines and generators with reuse value and resell them, accounting for about 45% of each car & mdash; 70% parts are reused.

With the acceleration of urbanization in China, the phenomenon of "garbage besieged city" is becoming more and more serious. About a quarter of cities in China have no landfill sites, and the accumulated land occupied by urban garbage dumps in China exceeds 500 million square meters, resulting in an annual economic loss of up to 30 billion yuan. Although burning garbage partially solves the problems of land occupation and groundwater pollution, it is not conducive to solving the atmospheric problem of frequent smog in China. China urgently needs to improve urban garbage disposal and actively deal with climate change and energy shortage. Germany is recognized as one of the countries with the earliest development of circular economy and the most experience in garbage disposal in the world. Learning from its relevant experience will help to improve the problems existing in garbage disposal in China.

Legal basis and management organization of garbage disposal in Germany

There are many laws and regulations on garbage management in Germany, involving various aspects and specific technical details. The Waste Disposal Law was first promulgated in 1972, while the Law on Circular Economy and Garbage Management in 1996 has a wide influence in the world, and it also started the circular economy in Germany. It is a programmatic regulation for developing circular economy and garbage disposal in Germany. The law defines some principles in garbage disposal, such as the polluter pays principle; Garbage is also a kind of resource, which can only be discarded when it can not be recycled under the conditions of existing technology. The scope of garbage disposal includes waste oil, packaging waste, batteries, scrapped cars and electronic waste. This regulation is supplemented by several more detailed regulations, such as Biological Waste Regulation, Landfill Regulation and Sludge Disposal Regulation.

Another significant thing is the "Regulations on Packaging Waste" implemented in 1991, which stipulates that the general "polluter pays" principle in environmental economics is extended to the field of production and consumption, that is, the producers and sellers of commodities are responsible for the recycling of their product packaging. This principle not only solves the problem of recycling and disposal of consumer waste, but more importantly, it encourages manufacturers to reduce waste at the source, such as improving technology to save the amount of raw materials, using recycled materials or simplifying product packaging. Today, this principle has been extended to many countries in Europe. In addition to the above-mentioned important laws and regulations, Germany has also promulgated wheelie bins Regulations, Scrap Cars Regulations, E-waste Regulations, Battery Regulations, etc., which are detailed to different types of waste and specific technical levels.

The highest management institution of German garbage disposal is the German Ministry of Environmental Protection and the professional agency Federal Environmental Protection Agency, which is mainly responsible for promulgating laws and state cooperation. The state environmental departments or regional organs and the State Administration for Industry and Commerce are senior management organs, mainly responsible for the implementation of relevant laws and regulations; There are also county and city management organs, which belong to lower management organs and are responsible for the whole process of garbage collection, transportation and disposal.

Organization and operation of garbage disposal in Germany

Based on the principle of extended production responsibility system, producers are responsible for the garbage they produce in the whole life cycle, but for many smaller producers and sellers, it is a big burden to establish their own recycling system. In view of this, in 1990, with the support of the German Federation of Industries and the German Chamber of Commerce and Industry, 95 companies in the retail, consumer goods and packaging industries spontaneously established the Green Point Company. The company is a private joint-stock enterprise, and it is non-profit. Green Point Company mainly aims at packaging garbage. By establishing a binary recycling system, on the one hand, manufacturers and sellers will be responsible for packaging recycling of their products, and on the other hand, their costs will be reduced. In this system, manufacturers and sellers pay Green Point Company to collect packaging garbage on their behalf, and Green Point Company then entrusts garbage recycling and utilization company to carry out follow-up work. The rate charged by Green Point Company to the manufacturer is often related to the environmental protection degree of the product packaging. The lower the environmental protection degree of the packaging, the higher the rate. Thus, Green Point Company has played a coordinating and organizing role in the whole system. Once the manufacturer entrusts the Green Point Company to engage in the garbage collection function on its behalf, they can attach the logo of the Green Point Company, that is, an arc-shaped green arrow, to the packaging of their products. Today, more than 90% of the products in Germany have the logo of Green Dot Company, and the model of Green Dot Company has been gradually extended to other European countries.

Classification and recovery of garbage disposal in Germany

The classification and recycling of garbage in Germany is very careful, so it is especially beneficial to the recycling and treatment of garbage. Generally speaking, all garbage can be divided into waste paper, light packaging, glass, clothes and shoes, biological garbage and residual garbage. The garbage put into the waste paper bucket (blue bucket) mainly includes newspapers, magazines, cardboard, toilet paper, etc. Leftover meals, peels, egg shells, fallen leaves, etc. are put into the biological trash can (brown bucket); Residual trash can (black bucket) is used to place other garbage that is not clearly classified, such as stockings, light bulbs, garbage cleaning, ballpoint pens, band-AIDS, broken toys, diapers, cigarette butts, etc. Plastic, aluminum, beverage cans, tin sheets, beverage boxes, yogurt cups, etc. are put into light packaging barrels (yellow barrels). In some cities, households put the packaging garbage into yellow garbage bags, and garbage trucks will take it away at a fixed time. The design of garbage trucks in Germany is also very user-friendly. Cleaning workers can automatically dump large boxes of garbage into the garbage trucks just by docking the garbage cans with the garbage trucks, saving manpower and time for garbage collection. For glass bottles, people need to throw them directly into special waste glass recycling bins on the street. Usually, such devices can be found near various communities, and glass bottles can be put into recycling bins according to three colors: white (transparent), green and brown. Similar to waste glass garbage, old clothes and shoes also have special collection points, but clothes need to be cleaned and wrapped before they are put into the garbage bin. After more than ten years of development, Germans have become accustomed to garbage sorting.

Enlightenment of German Experience to China

Comprehensively improve the laws and regulations on garbage management. Governments at all levels should formulate feasible laws and regulations, and strictly supervise them, especially the details of implementation, such as the requirements for garbage classification and recycling and how to classify them.

Actively adopt economic means to solve the problem of garbage sorting and recycling. Although China has carried out the pilot work of garbage sorting and recycling in many cities for a long time, the results are often a mere formality. The recyclable and non-recyclable garbage bins all over the streets do not play a classification role, and people do not make any distinction when throwing away garbage. In this regard, we can adopt the garbage charging system and the deposit refund system. Data and research in developed countries have shown that these economic means have remarkable effects on waste reduction and classified recycling. In Germany, the charge for residual garbage is often higher than other types of garbage, which encourages people to classify garbage more carefully.

Vigorously publicize the knowledge of garbage classification and promote the cultivation of people’s awareness of saving. Garbage classification is a meticulous and tedious work, which requires regular publicity and education activities with rich contents and various forms. On the other hand, guide the public to pursue a minimalist lifestyle and carry forward the fine tradition of thrift.

　　Recently, there have been cases of fraudulent use of rebranding software in some places. It is nothing new to cheat by using rebranding software, but why does rebranding software exist for a long time?

　　□ Our reporter Zhao Li

　　□ Intern of this newspaper Chen Hang

　　In fact, the number change software is a kind of Internet phone, which can be easily purchased and downloaded on the Internet a few years ago. With the increasing crackdown on telecommunication network fraud in recent years, the number of such frauds has been greatly reduced. However, in the interview, the reporter found that the channel of selling rebranding software online has not completely disappeared, but is more hidden.

　　Software sales channels are secret.

　　Li Jin, a Beijing white-collar worker who just bought a house this year, told reporters that when he looked at the house last year, he once bought the number change software online, and the trial period was one month. "The merchant gave me a link, and I clicked in a software installer. I installed it on my mobile phone, and I can really change the number to someone else’s. "

　　Li Jin told reporters that the price of using the rebranding software for one month is 600 yuan. He didn’t buy the rebranding software for illegal purposes. "Before I bought it, I called some intermediaries with my mobile phone number. Although I just asked them for information, I was miserable when I met the serial call from the intermediary. On a post about buying a house, I saw that some owners used the number change software to avoid the harassment of these intermediaries, and they didn’t have to change their numbers. I thought it was very convenient, so I bought it. " Li Jin said that after using it for a while, he never used it again. The website that sold me this software before was also blocked.

　　So, is this "magic" number change software really easy to buy? The reporter had a little experience.

　　In a software store, the reporter found that through keywords such as "change the number" and "display at will", the number change software could not be found, and only a small App in virtual operator was found. Strictly speaking, it can’t be regarded as the number change software, but a software similar to displaying the number of a non-local phone, which is mainly used for personal users to prevent harassment. If it is used for point-to-point number change fraud, it will be greatly restricted because the virtual number source is passively obtained.

　　The reporter searched for "rebranding software" on some e-commerce platforms, and the page showed "I’m very sorry, I didn’t find it with ‘ Number change software ’ Related baby. "

　　After searching for the keywords "number change" and "number change software" through a search engine, the reporter found nothing. Even if he turned back many pages, he could hardly find the relevant web pages, which were basically links to relevant news of the Ministry of Industry and Information Technology.

　　The reporter searched for "rebranding software" on the post bar and found that someone posted a post to promote rebranding software. The reporter then added the seller’s WeChat to talk to the seller. The seller claims that the buyer needs to pay the account opening fee in 340 yuan to activate as an advanced user. Advanced users can use the rebranding software to carry out activities such as salesman signing in and reporting for duty in different places, amusing friends, blessing confession, hiding personal privacy, social engineering test, entertainment network swindlers and so on. The seller told reporters that the usage fee of the rebranding software is 1 minute in 0.4 yuan, providing download channels for Android and Apple. It should be noted that the number change function cannot be used for national government numbers, bank numbers, public service numbers, common enterprise numbers, financial numbers, Xintong area numbers and common customer service numbers.

　　The reporter asked to test the software and let the seller call the reporter with the number of 188888888888, and then the reporter’s mobile phone showed the number of 1888888888.

　　The reporter then found a number-changing software named "Number-changing Treasure" on the Internet. official website showed that the software can "customize the display number of your own mobile phone, and all three networks are connected. The mobile phone numbers of China Mobile, China Unicom and China Telecom can be changed freely, which is completely customized, convenient and fast. After the reporter registered, it was found that the average user’s call charge was once in 1 yuan, and he could become a VIP user by recharging the balance of 20 yuan online, so he could make calls for free by using the "change number treasure". At the same time, the reporter’s investigation found that there are many restrictions on the use of the "rebranding treasure" software. For example, the fixed line or dialing the fixed line may be blocked or displayed incorrectly. It may not be available during the rush hour at night. If it is temporarily unavailable or does not call back, please call later. The call can’t be reached or the call is disconnected. Please change the display mode or try changing the called number type or area.

　　Harassment calls are "washed white"

　　"Because this phone is easy to operate, it is widely used. It is strictly prohibited to use this phone in illegal ways, so users and agents are requested to be self-disciplined, and offenders will bear the consequences themselves. Please use this phone legally, and the system will automatically detect it. Violators will be automatically sealed, and offenders will be handed over to the judicial authorities. This product is only for entertainment and chatting, and using this software is a personal act, and individuals will bear legal responsibilities for using this software. … …

　　Looking through the online advertisements of these "number changers", the reporter found that most of the "product introductions" have similar so-called "exemption clauses" at the end, and the enterprises that develop software are not responsible for their use at all.

　　Through the communication with the merchants, the reporter learned that there are two ways to change the mobile phone number. One is to buy a mobile phone card, and the seller sends the card to the user by mail, and the price is 500 yuan; Another way is to buy the rebranding software, which can be tested first. After the buyer approves and pays, the seller sends the software and the cracking code, and the price ranges from 200 to 300 yuan. Merchants told reporters that both methods can change the mobile phone number to any 11-digit number, "special numbers such as 110, 120 and 10086 are not available".

　　In fact, the whole process of number change software is very simple. Just enter the number you want to display in the software, and then enter your own mobile phone number. After simple settings, the system will show that the number change is successful.

　　Ge Jian, a network security engineer, said: "The rebranding software is equivalent to an Internet phone. In VoIP communication, in fact, the caller ID information we receive is equivalent to a data packet. If the number change software modifies the caller number in the data packet, the number we see on the phone and mobile phone is a modified false number. "

　　So how does the rebranding software work?

　　In this regard, Qin Hai, who works as a communication engineer in Beijing, told reporters that in the communication system, the calling number is transmitted by signaling. "Originally, the communication system was a closed system, and the telephone number was assigned by the operator, which was unique. The emergence of VoIP technology has changed this situation. VoIP technology enables users to make voice calls through the Internet, including voice communication with communication systems. Internet and communication system are interconnected by VoIP gateway, which has the signaling function of communication system and can receive and send signaling, including calling number transfer function ".

　　"Then the VoIP gateway transmits any calling number to the communication system through signaling, and the communication system will display any number on the called terminal (including mobile phone and calling display fixed telephone). Theoretically, VoIP gateway can display any number. If the operator is lax in the management of VoIP gateway, there is a loophole that VoIP gateway will send forged calling numbers into the communication system. This is how the number change software modifies the calling number through the VoIP gateway. " Qin Hai told reporters.

　　In addition, in the survey, the seller who sold the rebranding software told reporters that if the user’s original number has been marked as a sales call or a harassing call, it will not be displayed as a harassing call after changing the phone number with the rebranding software.

　　Direct callback to verify authenticity

　　However, the rebranding software is not high-tech.

　　In 2014, a 13-year-old junior high school student in Yancheng, Jiangsu Province made a number with the number of 1892222222 by using the number change software. Pretending to be a big boss, he used this super number to contact the marketing manager of a car rental company. The manager was so surprised that he thought he had met a big moneymaker. When the "boss" proposed to send eight luxury cars worth more than one million yuan to school to celebrate the children’s birthdays, it was even more obedient. But the sensation is a sensation, and it is true that it was "played" by children.

　　This is enough to show that the threshold for the use of rebranding software is really not high.

　　Is there a way to crack the rebranding software?

　　On this issue, the reporter interviewed Liu Yang, a mobile phone security expert. He told reporters that for this illegally used technology, the operator’s network system can’t identify it at all, so it is impossible to shield or deal with this "special call" accordingly. Although some people think it can be entertaining, this kind of software is suspected of breaking the law, and operators have never launched a similar service.

　　Liu Yang said that at present, the rebranding software has been used by some lawless elements. For example, some people use the rebranding software to impersonate the telephone numbers of government departments and even public security departments, looking for opportunities to defraud money. Therefore, changing the number of software will indeed lead to a crisis of trust and high-tech crimes.

　　How to prevent this kind of fraud? Liu Yang thinks that the easiest way is to call back. If the other party makes a call through this software and dials back according to the displayed number, the other party cannot answer. Therefore, when you receive a call from a familiar number, but the other party is a stranger, if the other party asks for remittance, sending money, etc., you must pay attention, don’t believe it easily, wait a moment and then call back the number to verify it. "To be on the safe side, if you encounter problems involving property such as borrowing money, you can meet friends to talk."

　　It is understood that at present, the national special campaign to crack down on new illegal crimes in telecommunications networks has achieved initial results, and the cases of fraud using rebranding software are generally on the decline. However, it is still necessary to be wary of some rebranding software operators taking face-lifting and secret means to avoid cracking down on governance, leaving rebranding software nowhere to hide. Last year, the Ministry of Industry and Information Technology issued the "Notice on Further Cleaning up and Rectifying Online Number Changing Software", which requires all basic telecom enterprises and Internet enterprises to take effective measures to resolutely block the online publishing, searching, dissemination and sales channels of the number changing software in websites, search engines, mobile phone application software stores, e-commerce platforms and social platforms, so that the number changing software can’t be sent, seen, searched or downloaded.

　　In 2016 alone, a total of 269 keywords (rebranding software) were blocked by the joint search engine of 12321 Network and Bad Information Reporting Center, with more than 200 million search results blocked, more than 290,000 download links deleted, and nearly 100 mobile phone application stores were United, and a total of 682 illegal rebranding software were removed.

　　Cartography/Gao Yue　　

CCTV News:Under the background of peak carbon dioxide emissions and carbon neutrality, China has stood at the crossroads of energy transformation. Clean, low-carbon, safe and efficient new energy is becoming the main force of "double carbon" track, and it also presses the "acceleration key" for the development of new quality productivity. Rapid iterative new technologies link up more efficient energy arteries, and the growing new energy is also moving towards a lower-carbon green future at a faster pace.

The micro-documentary "Accelerating the Development of New Productive Forces" of Finance and Economics Program Center aired the third episode — — Energy is trendy, let’s take a look at how the surging new energy is "chasing the wind day by day" and going to the sea.

In ancient times, primitive people learned to drill wood for fire, and human civilization started; Coal ignited the fire of the first industrial revolution; The invention of electricity achieved a qualitative leap in productivity; The outbreak of oil industry further accelerated the global industrialization; Every breakthrough in the field of energy is inseparable from the progress of human civilization. Today, we have once again reached the crossroads of energy transformation.

Changing electricity is a job that taxi driver Master Fan has to do every afternoon. It takes only 3 minutes to replace two standardized batteries each time, and the power is 53 degrees.

Master Fan Taxi Driver:We have a 12-hour class, two people are driving this car, and one class (electricity package) is in 45 yuan (one day).

In Xiamen, the basic network of power exchange is under construction, and each power exchange station uses the same standard battery to adapt to different models.

Chen Weifeng, General Manager of Times Electric Service:Just like a "No.5 battery", all kinds of vehicles will use this "No.5 battery" in the future. The optimization of peak power and valley power and user behavior can reduce the cost of electricity.

Gao Mingyuan, General Manager of Xiamen Strait Taxi Company:At present, 275 taxis have been put into operation, and drivers have no mileage anxiety.

Each power exchange station is like a large-scale city charging treasure, which is fully charged at night when electricity consumption is low, and provides power exchange service for local operating vehicles at daytime when electricity consumption is high. The power of these large charging treasures responds to the dispatching of the power grid, and where do their power sources come from?

In this sea area located in the southeast of Zhangpu County, Fujian Province, the offshore wind farm is carrying out fan hoisting.

This offshore wind farm, which is 32.8 kilometers away from the coastline, includes 28 13 MW and above wind turbines, including 6 16 MW wind turbines with a total installed capacity of 400 MW. The hub center of the 16 MW fan is 152 meters high, which is equivalent to the height of a 52-story building, and a single blade is 123 meters long.

On the sea, a 16 MW fan can generate about 34 degrees of electricity every revolution. According to this calculation, a single unit can output more than 66 million kWh of clean electricity every year, which can meet the domestic electricity consumption of 36,000 families of three for one year. Every time I turn on electricity, I remember which sea area I come from.

Lin Yufeng, Director of Development Department of State Grid Xiamen Power Supply Company:The electricity it sends out can be stored on the chain, which can prove which power plant the electricity is sent from, and then they can be traced back to the source when they trade green electricity.

However, like all renewable energy sources, the biggest drawback of wind power lies in the instability of random fluctuations.

Uncontrolled wind is free and willful, but the demand for electricity is 24 hours a day. To adjust the time difference between supply and demand, energy storage facilities are exploring new solutions.

Let’s answer the question just now. Changing power stations is one of the solutions. These large-scale city charging treasures solve the problem of storing wind and then send electricity into the car. However, the exchange of electricity is not just a one-way traffic to send electricity into the car.

New energy owners:At night, when the electricity bill is low, fully charge the car, and use it to charge it to the power grid in the daytime to earn the difference.

Here, the new V2G charging pile turns the electric vehicle into a small-sized "charging treasure", which sends electricity to the power grid in the reverse direction during the peak hours to help peak shaving. The reverse charging technology realizes the two-way interaction between the vehicle and the power grid.

Wang Laihui, Deputy Manager of State Grid Xiamen Electric Vehicle Company:Now it’s generally 60 degrees, and you can run 400 kilometers a day. One day, 30% of electricity is discharged reversely, and the price difference per kilowatt-hour is about 0.65 yuan, and the discharge income per day is about 12 yuan. It is very suitable for office workers to charge at home at night and discharge at the office during the day.

The inexhaustible electricity in the car can be fed back to the power grid, which may have been a fantasy in the past. Technological innovation has brought more possibilities for new energy and allowed more imagination to take root. Since 2023, China’s new energy industry chain has repeatedly broken the world record. The world’s first 16 MW domestic offshore wind turbine was successfully connected to the grid for power generation, and the world’s largest 18 MW direct-drive offshore wind turbine was successfully rolled off the assembly line. The onshore 15 MW model has also been released.

Kun yang, Executive Vice President of China Electric Power Enterprise Federation:During the "Fourteenth Five-Year Plan" and "Tenth Five-Year Plan" period, the cumulative investment scale of new power sources in China can reach more than 10 trillion yuan, in which the new energy industry will play an important role.

Under the background of peak carbon dioxide emissions and carbon neutrality, China’s energy structure is accelerating, and clean, low-carbon, safe and efficient new energy is becoming the main force of the "double carbon" track. The new energy of "chasing the wind day by day" and going into the sea has injected a steady stream of power into the process of high-quality development.

He Yang, Deputy Director of the National Energy Administration:We will seize the commanding heights of new energy development technology in the future by strengthening the cutting-edge and subversive technical research of wind power and photovoltaic, and promote the technological innovation and application of new energy engineering in major projects such as large-scale wind power photovoltaic base projects and offshore wind power base projects.

Non-renewable fossil fuels and their changes in climate conditions have a profound impact on the transformation of global energy structure. A century ago, human beings were surprised that several groups of copper wires at home or in factories could create the energy of a turbulent river; Today, we have begun to try to get rid of the dependence on fossil resources and explore the possibility of sunlight, wind, river water and even hydrogen. New technologies that accelerate iteration link more efficient energy arteries, and growing new energy sources are also accelerating towards a lower-carbon green future.

He Yang, Deputy Director of the National Energy Administration:Through these new models and formats, we will build a zero-carbon factory and a zero-carbon park, further catalyze and stimulate new energy as a new quality productivity, and form a new kinetic energy for green and sustainable growth.

The immortal fire ignited the engine of civilization, the inexhaustible sea breeze drove the wheels forward, the surging waves were expected, and the surging energy was endless. Taking fire, burning lamps, accumulating potential and storing energy, the energy trends are one after another, and the future is on the road.

　　BEIJING, July 25 (Xinhua)-The Report on the Quality Monitoring of Compulsory Education in China has been officially released recently by the Quality Monitoring Center of Basic Education of the Ministry of Education (hereinafter referred to as the Monitoring Center). The monitoring center interprets this, saying that China not only regards Chinese, mathematics and science as the important subjects of national compulsory education quality monitoring, but also brings moral education, physical education and art into the monitoring field, which covers a wide range of disciplines, highlighting the importance of China’s monitoring for students’ all-round development.

　　The following is the explanation of the monitoring center for the relevant situation and main characteristics of monitoring work:

　　First, based on the national conditions of China, according to the curriculum standards to develop indicators and tools.

　　Curriculum standards are the basic norms and quality requirements of the state for basic education courses, which reflect the basic requirements of the state for students at different stages in knowledge and skills, processes and methods, emotional attitudes and values. Different from international large-scale education evaluation projects, the quality monitoring of compulsory education in China is strictly based on the national curriculum standards, and the monitoring index system and tools fully reflect the basic requirements of the national curriculum standards. The results can help us understand the learning situation of Chinese students, and then accurately grasp the implementation and implementation of the national curriculum standards.

　　In addition to strictly following the national curriculum standards, in the process of developing monitoring standards and tools, China’s monitoring system also systematically analyzed the relevant laws, regulations and policy requirements, went deep into the front line of education to conduct extensive research, and conducted several trial tests before the formal monitoring, so as to ensure that the monitoring indicators and tools are in line with the actual education and teaching, have wide applicability, and can comprehensively and accurately evaluate the development status of students in compulsory education in China.

　　Second, advocate the educational concept of all-round development and highlight the ability orientation.

　　Promoting the all-round development of students’ morality, intelligence, physique and beauty is an important goal and requirement of basic education in China. China not only regards Chinese, mathematics and science as the important subjects of national compulsory education quality monitoring, but also brings moral education, physical education and art into the monitoring field, which covers a wide range of subjects, highlighting the importance of China’s monitoring on students’ all-round development. At the same time, China’s monitoring adheres to the ability orientation, focusing on the test of students’ comprehensive application of knowledge and problem-solving ability, gradually guiding the whole society and the education system to optimize the training program, and devoting itself to the cultivation and promotion of students’ multi-level ability. In all disciplines and fields, tests based on real life situations are emphasized; In the monitoring of sports and art, the test of performance ability such as sports, singing and painting is emphasized.

　　Third, pay attention to the monitoring of key related factors of education quality, and identify the focus of quality improvement.

　　The quality monitoring of compulsory education in China not only pays attention to the quality of compulsory education, but also analyzes the key factors affecting the quality of compulsory education. In the process of demonstrating and selecting the indicators related to the quality of compulsory education, we should sort out and analyze the relevant educational policies of the Party and the state, comprehensively consult and systematically analyze the latest research progress, seriously study the hot and difficult issues and outstanding problems in China’s education, and focus on curriculum setting, condition guarantee, teacher allocation, subject teaching and school management in six monitoring disciplines, so as to provide a focus for improving education and quality.

　　Taking scientific monitoring as an example, in addition to evaluating students’ scientific academic performance, we also investigated the curriculum, homework time, teachers’ academic qualifications, inquiry-based teaching behavior, and the use of educational and teaching resources, in order to find out the key factors that may affect students’ academic performance and provide more targeted and effective guidance and reference for education and teaching. For example, the correlation analysis shows that teachers’ inquiry teaching level is closely related to students’ scientific academic performance. Taking the fourth grade as an example, compared with teachers with low inquiry teaching level, the proportion of students with high inquiry teaching level who have reached the intermediate and above level is 9.7 percentage points higher, and the proportion of students who have reached the excellent level is 12.7 percentage points higher. The same rule also exists in physics, biology and geography in the eighth grade.

　　Four, bring together high-level talents from many disciplines and fields to participate in the monitoring work.

　　By building an open platform, the monitoring center has effectively integrated resources and strengths in related fields at home and abroad, providing important talent guarantee and intellectual support for the quality monitoring of national compulsory education. In 2015— During the first cycle of monitoring in 2017, more than 1,000 experts in education measurement and evaluation, curriculum and teaching theory, education policy and other fields, as well as local education administration experts, teaching researchers, primary and secondary school principals and front-line teachers were invited to participate in the selection of monitoring indicators in related disciplines and the research and development of monitoring tools; A team of more than 500 monitoring guides was selected and set up nationwide to participate in the supervision and guidance of monitoring implementation; More than 40 overseas experts from 20 countries, regions and international organizations were invited to provide technical consultation and professional services for monitoring. By bringing together experts from many disciplines and fields, the professionalism and sustainable development of monitoring are effectively guaranteed.

　　Five, the use of advanced measurement technology and information means, combined with the actual monitoring to be innovative.

　　In the design of monitoring tools, considering the extensiveness of test content and the limited time for students to answer, and in order to prevent cheating, matrix sampling design is adopted, and multiple-question books are used in the same subject; In order to solve the comparability of students’ academic performance in different years, the test equivalence technology is adopted to measure students’ academic performance in different years on the same ruler, so that students’ academic performance in different years can be compared and longitudinal tracking analysis of students’ academic performance can be realized. In the monitoring sampling work, combined with the actual situation in China, the "school-student" two-stage sampling method widely used in international education quality monitoring is changed to the "district-county-school-student" three-stage sampling method, which can not only fully grasp the situation of the whole country and provinces, but also greatly improve the monitoring operability. On the technical means of monitoring, the electronic singing system is used to test the students’ singing ability. During the test, students sang songs on the spot and uploaded them to the test system in real time. Based on the artificial intelligence scoring system, the automatic scoring of students’ singing ability was realized, which solved the problem of data collection and scoring in large-scale singing ability test.

　　Six, build a strict and standardized data collection process, strengthen the supervision and management of the implementation process.

　　Objective and true data is the "lifeline" of the whole monitoring work. The national compulsory education quality monitoring has formulated a strict and standardized data collection workflow and a minute-long work schedule, and defined the sequence, specific requirements and time nodes of each work to ensure that the data collection work is standardized and orderly. The monitoring implementation progress management system is adopted to monitor and guide the implementation process of monitoring organizations in provinces, counties and schools in real time, and collect and follow up information at different levels, which effectively improves the management efficiency and quality of monitoring organization implementation. At the same time, organize visual experts to conduct special supervision and inspection on the monitoring preparations in some provinces in China, and urge and guide local governments to do a good job in monitoring preparations; The teachers of the non-sample school serve as testers, who are responsible for supervising the whole process and patrolling the test work; Half an hour before the start of the test, unpack the monitoring toolkit and the confidential student roster, publish the student list in the monitoring bulletin board and accept supervision; During the test, we can guide and monitor the test in real time through QQ group, WeChat group and hotline. Through the above measures, the data collection work is standardized, orderly and efficient, and the objectivity and truth of monitoring data are effectively guaranteed.

　　Seven, innovative application of results, to help educational decision-making and improvement of education and teaching.

　　Monitoring is only a means, and improving and upgrading the quality of education is the purpose. Based on the monitoring data, the monitoring center has written different results reports and submitted them to the relevant national education departments, which provides an important reference for educational decision-making. At the same time, the monitoring center also provides monitoring results reports to all participating provinces and sample counties (cities, districts) every year, and organizes interpretation meetings of monitoring results reports to help local personnel understand the monitoring data results and promote the application of monitoring results. For example, in September 2017, the monitoring center held a provincial monitoring result report interpretation meeting in sub-districts across the country, and 32 provincial units and all their sample counties participated in the interpretation meeting. In addition, it also provides professional support for some districts and counties to carry out improvement work based on monitoring results.

Health times

Authoritative health information, trusted by professionalism!

Many obese and overweight people take diet pills, drink diet tea, skip dinner and deliberately go on a diet … These unscientific ways of losing weight may also lose weight in the short term, but they affect their health and are easy to rebound.

Lose 10 pounds a month without rebounding.

Concord doctors give three ways to lose weight.

How to lose weight healthily without rebounding? Chen Wei, deputy director of the Clinical Nutrition Department of Peking Union Medical College Hospital, issued a document in 2020 introducing the scientific weight loss methods used in three hospitals, which are applicable to the general public! ①

1, 5+2 fast food: an average of 5 kg a month.

7 days a week, eat normally for 5 days, and skip food for 2 consecutive days.

Note that this fast food is not to eat nothing, but to limit the food intake. Micronutrients, carbohydrates, fats and protein in the four major nutrients should be taken in proportion. The calorie intake should be properly controlled on non-fasting days. The recommended total calorie for women is 1200-1500 kcal/day, and that for men is 1500-1800 kcal/day. The non-fasting days should be adjusted according to the proportion.

Such intermittent scientific fasting will not only be harmful to health, but also "restart" some functions of the body, which is beneficial to health.

5+2 fast food recipe reference table

[Non-fasting day]

Breakfast at 7:30:

The staple food is 50 grams thick and thin;

Protein food (1 egg+milk/soybean milk 250ml);

A multivitamin.

Extra meal at 10:00:

150 grams of skim yogurt.

Lunch at 12:00:

The staple food is 50 grams thick and thin;

Protein food 100 grams (50 grams of lean meat +1 egg or tofu 100 grams or dried bean curd 50 grams);

250 grams of vegetables.

Extra meal at 16:30:

200 grams of fruit.

Dinner at 18:30:

The staple food is 50 grams thick and thin;

Protein food 100 grams (50 grams of lean meat +1 protein or 100 grams of tofu or 50 grams of dried bean curd);

250 grams of vegetables.

[fasting day]

Breakfast at 7:30:

1 egg;

100g skim milk/low-fat yogurt;

A multivitamin.

Lunch at 12:00:

150 to 200 grams of fruit.

Dinner at 18:30:

25 grams of staple food;

Boiled vegetables 200 grams;

Protein food 50 grams.

Drinking water for the whole day is 2500 ml.

2, limited energy and balanced nutrition diet: an average of 2-4 kg a month.

The total energy intake per day is reduced by 1/3 or by 300-500 kcal.

You can also ignore calories, except water, and reduce all kinds of foods you usually eat, such as the staple food of three meals a day, meat, eggs, vegetables and milk, as well as fruits and yogurt with extra meals, by 1/4 evenly, which is a good "diet meal" if you stick to it for a long time.

The advantage of losing weight in this way is balanced nutrition, and protein, fat, carbohydrates, vitamins, trace elements, etc. can be evenly ingested, and the operation is simple and convenient for long-term implementation. The disadvantage is that the speed of weight loss is not fast enough and it needs long-term persistence.

3, low-carbon water and high protein diet: you can lose 10 pounds a month.

Use high-protein foods, such as lean meat, protein, low-fat dairy products and other natural foods, or nutritional products such as protein powder and nutritional meal replacement to replace one to one and a half meals a day, so as to achieve the purpose of limiting the total energy intake and quickly losing weight.

This kind of weight loss is faster, and it can be reduced by 15-20 kg for 3-4 months in a row. People who need short, flat and fast weight loss in clinic generally choose this method. However, it doesn’t conform to our daily eating habits, and if you choose protein powder and meal replacement, you must choose a full-nutrition product that meets the relevant national standards, so that you can meet the nutritional and health needs while losing weight. Don’t mistake it for a weight-loss product that doesn’t meet the requirements.

These methods are selected by doctors by studying the relevant literature at home and abroad, summarizing many weight-loss methods, combining the actual data of mass weight loss and combining the physique of Chinese people.

According to the statistics of outpatient service, with these three methods, overweight or obese people can lose 1-5 kilograms in the first month, and they can lose the same weight every month for three months to six months before reaching their suitable weight, and they can not rebound as long as they continue to adhere to it. Because the weight is regulated by adjusting the food collocation, it has a high degree of safety and is suitable for most people who need to lose weight. ①

Why many people fail to lose weight?

Some people use blind dieting, devil exercise training, taking weight-loss drugs and other methods to lose weight, but they fail to lose weight again and again.

Director Chen Wei issued a document in 2019, saying that because these methods are physically and psychologically destructive to people’s weight loss, they only achieve the goal of reducing "weight" by numbers. Unfortunately, it is not fat but precious water and muscle.

After a little while, you may relax, slack off, and can’t bear the torture. At this time, "weight" will rebound and even increase at a multiple rate. This is what doctors often call the "yo-yo effect" in clinic. The weight drops by 10 kg and rises back to 20 kg! ②

These weight loss misunderstandings should be avoided.

1. Don’t eat or eat dinner after noon.

Although there was a saying in ancient times that "no food after noon", with the development of society and the change of living habits, three meals a day are now advocated.

If you don’t eat dinner, your brain will send out a strong appetite signal when you are on an empty stomach for more than ten hours the next day, preferring high-calorie foods, making it easier to take revenge meals and storing fat more easily. ①

2, don’t eat staple food, only eat water to cook.

Fat-reducing meals such as boiled vegetables are also unreliable, which belongs to the extremely low energy intake method, and similarly, not eating staple foods, etc., which are unhealthy and will rebound quickly once they return to normal diet.

Moreover, the human body also has a certain demand for oil intake. If there is no oil at all or too little oil intake, it may also cause the lack of essential fatty acids and cause diseases. ①

3. Replace normal diet with meal replacement.

Dai Yongmei, director of the Nutrition Department of Nanjing Maternal and Child Health Hospital, Jiangsu Province, said in the Health Times in 2020 that eating meal replacement did play a certain role in losing weight at the beginning. Compared with simple dieting, it can provide satiety and supplement nutrition at the same time, but don’t just eat meal replacement all day.

Food should be reduced by combining reasonable diet with meal replacement. For example, properly reduce the intake of staple food, replace it with meal replacement powder or meal replacement stick, and eat other vegetables, fish and shrimp as usual. ③

4. Lose weight by eating fruit

Zhang Xiaoyan, former director of the Nutrition Department of Lianyungang Maternal and Child Health Hospital in Jiangsu Province, said in the Health Times article in 2019 that many people have heard that eating fruit is good for losing weight, so they eat a lot of fruit a day, but they have gained weight unexpectedly.

Some fruits are not low in calories. A bowl of rice contains about 75 grams of carbohydrates, and half a watermelon is equivalent to two bowls of rice. If you eat a lot of fruit in addition to the normal three meals, losing weight is just a dream. If you like to eat high-calorie fruits like durian again, you will only get fatter and fatter. ④

5. Eat a lot of coarse grains

Some people eat a lot of coarse grains and think they can clear their intestines and lose weight. Yu Wanting, a clinical nutritionist in the Clinical Nutrition Department of the Third People’s Hospital of Chengdu, Sichuan Province, said in the Health Times article in 2018 that coarse grains can supplement dietary fiber and contain more B vitamins.

However, if suddenly ingested in large quantities, the stomach and intestines are difficult to adapt in a short time, but it is easy to cause indigestion. If you eat too much coarse grains and can’t replenish enough water, it is easy to aggravate constipation. ⑤

6. Use weight-loss drugs

Huang Fang, a physician in the Department of Critical Care Medicine in the First Affiliated Hospital of Soochow University, said in the Health Times in 2018 that some weight-loss drugs on the market have not been clinically tested and have not been approved by the state. These drugs contain substances that act on the brain, thyroid and liver, laxatives and other ingredients, and the dosage is not clear. After taking them, they are very harmful and cannot really lose weight.

Don’t take medicine on your own to lose weight. It’s better to eat and exercise. Even taking medicine should be carried out under the guidance of a hospital nutritionist. ⑥

Finally, it should be emphasized that the ideal weight loss effect can be achieved simply by adjusting diet, but if you want to be healthy, you should also exercise moderately!
