　　How and why tornadoes form? What to do when encountering tornadoes? What direction to escape and self-help skills?

　　How is a tornado caused? How to save yourself when encountering a tornado? The reason for the formation of tornado is that the temperature difference between the upper and lower clouds is too large, resulting in a small vortex in which cold air drops and hot air rises; At this time, pieces of cotton-like white clouds appear in the air, which are called cumulus clouds. Then, cumulus clouds continue to develop in the maelstrom to form cumulonimbus clouds, and the latent heat inside the cumulonimbus clouds continues to heat up, thus generating a powerful airflow, which is called a tornado.

　　At about 5: 15pm on July 3rd, a sudden tornado hit kaiyuan city, Liaoning Province, with a wind speed of 23m/s (magnitude 9) nearby. The tornado was formed by Jingouzi Town, passed through Xingkai Street and Kaiyuan Economic Development Zone, and lasted for 15 minutes to the south, then weakened into a low pressure.

　　Tornadoes caused casualties, damaged houses and damaged power communication to varying degrees.

　　At present, preliminary statistics have caused 6 deaths and more than 120 injuries. The specific situation is being counted. On-site rescue is being carried out in an orderly manner.

　　How to save yourself when encountering a tornado? Sort out the escape skills when encountering a tornado, hoping to help more people!

What are the escape skills when encountering a tornado?

　　Understand the signs of tornadoes. First of all, there will be some natural phenomena before tornadoes appear, often accompanied by black clouds, cumulonimbus clouds and lightning and thunder. In addition, cold wind, strong wind, heavy rain and hail are signs of tornadoes. To get to a safe place quickly, tornadoes are very terrible. The bottom of black clouds forms a funnel shape, and the wind speed can exceed 70 meters per second, which can roll up the car and run into the air. Different from the typhoon, with the swirling updraft, the objects on the ground along the way are also rolled up, and the rolled-up objects smash the glass of the building, causing the air pressure in the rented house to change sharply and the roof will be overturned.

　　When we encounter a tornado, don’t panic. The following escape skills and precautions are to be remembered.

　　1. When people are outdoors, it is important to hide in a strong building made of reinforced concrete. Never hide in garages, prefabricated buildings and black wooden storage sheds.

　　2. When there are no buildings nearby, cover your head and neck with your hands and dive into ditches and depressions on the spot.

　　3. When people are indoors, close the windows and draw the curtains, and don’t get close to the wall; Never be in danger because you concentrate on tornadoes; Located in the middle of the first floor in a two-story building; Rooms and toilets without windows are relatively safe for people; You can also cover your head and neck with your hands in the bathtub or under the table.

　　Precautions: Once you notice a tornado approaching, you should immediately escape to a safe place.

How to save yourself when encountering a tornado?

　　1. Identify tornadoes accurately

　　Experts remind: Tornadoes occur in thunderstorms in summer and autumn, especially in the afternoon to dusk. When the roller cloud and funnel cloud were invented, it was a sign of a tornado, and it was usually accompanied by a hearty whistle! (10,000% of the time, because the speed at which the tornado began to move was annoying, it was careless. Don’t be busy making friends at this time!

　　2. How to run after escape

　　If you have enough time to escape, you must escape from the room. Be sure to stay away from dangerous houses and mobile homes, trees and telephone poles, and then retreat to the direction perpendicular to the movement of tornadoes (tornadoes usually don’t turn), and just hide in low-lying areas as a cover, and pay attention to cover your head.

　　3. Accurate practice indoors

　　When a tornado comes, if you can’t escape in the room, try to close some windows, but never close them all. The goal of this is to balance the pressure inside and outside the building. Just hide in the closet or basement, face the wall and hold your head down.

　　4. What should I do in the car?

　　Whether cars, bicycles or motorcycles are invented early, we must look at the vertical deviation from the wind belt. Otherwise, you should get off the bus immediately and find a suitable escape area around you (exaggerate again, pay attention to leaving trees and telephone poles). Don’t hide in or under the car, it is easy to be swept away.

　　5. What is the best place to avoid tornadoes?

　　A basements, bomb shelters, and the lowest floors of high-rise buildings that will not be swept away by the wind, flooded or blocked by equipment are the best places to avoid tornadoes.

　　B. If you are in a school, hospital, workshop or shopping center, you should avoid the indoor room or lobby closest to the ground. Stay away from places with glass or wide roofs in the surrounding environment.

　　C. When encountering a tornado in the open field, you can choose to lie down in low-lying places such as canals and river beds.

　　D. warning: don’t go to halls, stacks, and temporary buildings to avoid such open and unsafe occasions.

　　6, immediately leave the bridge, high ridge, coastal and dangerous houses, mobile homes. If there is no barrier around, you should lie flat in a low-lying place, but pay attention to waterproofing!

　　Remind everyone that it is important to save your life, but never hurry, prevent crowding, help each other, and save yourself in an orderly manner. If you have valuables to transfer, you are advised to abandon them and run away.

　　　　　　　CCTV News:On the 6th local time, just a few hours before the new round of US sanctions against Iran came into effect, Iranian President Rouhani accepted an interview with Iranian domestic media. In the interview, he said that he would not accept the way that the United States wants to negotiate and restart the sanctions at the same time, and stressed that economic pressure and sanctions will not force Iran to return to the negotiating table.

　　　　　　 In a TV interview that day, Rouhani said that it was meaningless for Iran that the United States restarted sanctions while wanting peace talks. On the one hand, the United States was trying to create division and panic for the Iranian country and people, and on the other hand, it was forced by the pressure of mid-term elections in the United States. Rouhani said that Iran has always been willing to negotiate, but the United States must first show sincerity. At the same time, Rouhani said that the United States is now isolated in the world, and the United States will regret its imposition of sanctions, and called on Iran to unite against US sanctions.

　　　　　　 The United States restarts sanctions against Iran in non-energy fields.

　　　　　　 The US White House issued a statement on the 6th, announcing that the United States will restart a series of non-energy sanctions against Iran in the fields of finance, metals, minerals and automobiles on the 7th. The White House statement said that the sanctions will involve the Iranian government’s purchase of precious metals such as dollars and gold; Industrial graphite, steel, aluminum, coal and software; Transactions related to Iranian currency; Activities related to the issuance of sovereign debt by the Iranian government; Iranian automobile industry.

　　　　　　 The United States will restart the remaining sanctions against Iran on November 5, involving Iranian port operators, energy, shipping and shipbuilding industries; Petroleum transactions; Foreign financial institutions deal with Iran’s central bank.

　　　　　　 Iran’s multi-pronged response to the threat of US sanctions

　　　　　　 Faced with the threat of sanctions from the United States, Iran has taken various measures to reduce the possible negative impact.

　　　　　　 On the evening of 5th local time in Iran, the Iranian government suddenly announced that it would reopen the foreign exchange business of foreign exchange bureaux, but the specific trading measures need to be further announced. In an interview with Iranian state television, the governor of Iran’s central bank, Hamadi, said that this measure was taken to show that Iran has the ability to stabilize the foreign exchange market when the US sanctions come into effect. He also stressed that it will continue to pay attention to the prices of people’s daily necessities and will maintain the price stability of daily necessities and medicines.

　　　　　　 In addition, Iran’s national television station No.5 broadcast a statement of Iran’s Islamic Revolutionary Guard Corps, saying that the Revolutionary Guard Navy had recently conducted military exercises in Persian Gulf waters. The media quoted a spokesman for the Revolutionary Guard as saying that the military exercise was a routine exercise aimed at ensuring the safety of international sea routes. However, he did not disclose more detailed information such as the specific time and scale of the exercise. Iranian President Rouhani has hinted that if Iranian crude oil exports are blocked, then Iran may block the the Strait of Hormuz. The Strait of Hormuz is a shipping artery connecting Persian Gulf and Gulf of Oman in southern Iran, which has a strategic impact on global energy supply. Some analysts said that Iran held this military exercise on the eve of the resumption of sanctions against Iran by the United States, with the intention of sending a tough signal to the United States.

　　In the two sessions of the National People’s Congress in 2024, the General Secretary of the Supreme Leader went to the group for deliberation and discussion three times, and had in-depth exchanges with the deputies and discussed the country.

　　Talk about achievements, situation, countermeasures and demands … … The general secretary made a series of important expositions to guide the future development direction.

　　"Develop new quality productivity according to local conditions"

　　When attending the deliberation of the Jiangsu delegation, General Secretary of the Supreme Leader stressed: "We must firmly grasp the primary task of high-quality development and develop new quality productivity according to local conditions."

　　The word "adjust measures to local conditions" is thought-provoking.

　　When all localities and departments are scrambling to lay out new-quality productive forces, the General Secretary put forward the idea of "proceeding from reality, first establishing and then breaking, adapting to local conditions, and guiding by classification", which means that all localities and departments should not rely solely on enthusiasm and rush headlong into action, but stick to their own reality and insist on "opening a lock with one key" to ensure that the development of new-quality productive forces can be promoted in an orderly manner and achieve practical results.

　　"Don’t neglect or give up traditional industries", "Prevent rushing headlong into mass action and bubble" and "Don’t engage in a model" … … Plain words and pragmatic requirements point out that the relationship between emerging industries, future industries and traditional industries should be handled well in developing new quality productive forces.

　　When attending the plenary session of the delegation of the People’s Liberation Army and the Armed Police Force, the General Secretary emphasized "promoting the efficient integration and two-way pull of new quality productivity and new quality combat effectiveness" and "creating a growth pole of new quality productivity and new quality combat effectiveness", conveying the firm will to accelerate the promotion of new quality combat effectiveness.

　　"Plan major measures to further comprehensively deepen reform"

　　The fourth meeting of the Central Committee for Comprehensively Deepening Reform held not long ago released an important signal: this year is another important year for comprehensively deepening reform, and the main task is to plan for further comprehensively deepening reform.

　　At the National People’s Congress, General Secretary of the Supreme Leader made further arrangements:

　　In the Jiangsu delegation, it is proposed to "deepen the reform of science and technology system, education system and talent system, and get through the blocking points that constrain the development of new quality productive forces"; At the joint meeting of CPPCC sectors, it was emphasized to promote ecological protection and restoration and solve outstanding problems of ecological environment with the system of "reform ideas".

　　Focusing on solving deep-seated institutional obstacles and structural contradictions, and rushing to solve the most prominent problems, the General Secretary pointed out some key areas for further comprehensive deepening of reform.

　　"Promoting scientific and technological innovation and industrial innovation as a whole"

　　In the process of promoting high-quality development, the importance of technological innovation is self-evident. General Secretary of the Supreme Leader has always attached great importance to strengthening the deep integration of scientific and technological innovation and industrial innovation.

　　Scientific and technological innovation is the decisive premise and key support of industrial innovation, and industrial innovation is the foothold of the transfer and transformation of scientific and technological innovation achievements.

　　At the joint meeting of the Chinese People’s Political Consultative Conference, the general secretary affirmed the direction of promoting scientific and technological innovation and industrial innovation as a whole: "In the past, research and production were ‘ Two skins ’ At present, the conversion rate of scientific research achievements is much higher than in the past, especially the direct research and development of enterprises themselves forms the transformation of achievements, and colleges and enterprises form a community. This trend and direction are right, so we should redouble our efforts to further improve the incentive and promotion policies. "

　　Promoting scientific and technological innovation and industrial innovation as a whole means taking scientific and technological innovation as the guide, promoting the upgrading of traditional industries, the growth of emerging industries and the cultivation of future industries as a whole, so as to accelerate the innovation achievements from "laboratory" to "production line" and transform them into real productivity and new quality productivity, and inject more abundant kinetic energy into high-quality development.

　　"Support high-quality development with high-level protection"

　　Report to the 20th CPC National Congress of the Communist Party of China pointed out that "promoting green and low-carbon economic and social development is the key link to achieve high-quality development", revealing that high-quality development and high-level protection are complementary and dialectical unity.

　　From last year’s National Ecological Environmental Protection Conference, it was emphasized that "through high-level environmental protection, we will constantly shape new kinetic energy and new advantages for development", and at this joint meeting of the Chinese People’s Political Consultative Conference, it was put forward that "supporting high-quality development with high-level protection" fully reflected the broad vision and dialectical thinking of the General Secretary.

　　The direction is clearer: transform ecological advantages into development advantages with high-level protection, realize a virtuous circle of protection and development, and thus promote green economic and social transformation and sustainable high-quality development.

　　"To realize Chinese modernization, the Internet must pass"

　　At the joint meeting of the Chinese People’s Political Consultative Conference, Wu Jianping, a member from the scientific and technological circles, said: "We must strive to realize the independent control of the core technologies of the next generation Internet, and firmly grasp the initiative of innovation and development of network powers in our own hands."

　　General Secretary of the Supreme Leader agreed with Commissioner Wu Jianping’s point of view: "To realize Chinese modernization, the Internet must pass."

　　Building a network power is the foundation to achieve high-quality development, and the core technology of the Internet is the "life gate" of a network power.

　　We should grasp the initiative of innovation of cyber powers. Only by self-reliance and technological innovation can we calmly deal with all kinds of cyber security threats, support the two-wheel drive of cyberspace security and development, and help Chinese modernization with the construction of cyber powers.

　　"Great country craftsmen are the cornerstone and pillar of our Chinese nation building"

　　Craftsman spirit is the national temperament of the Chinese nation, which is rigorous, earnest, persevering and pursuing Excellence. Throughout the ages, the craftsman spirit has been changing and shaping China.

　　Great country craftsmen who strive for perfection and "haggle over every ounce" constantly polish the heavy weapons made and forged in China. The General Secretary of the Supreme Leader praised, "It is necessary to establish the spirit of artisans and cultivate the first-line great country craftsmen in batches. This is the pillar. Without Jin Gangzuan, we can’t do porcelain work. ".

　　The development of the times requires great country craftsmen; Towards a new journey, we need to vigorously carry forward the spirit of artisans. In today’s high-quality development, artisans in big countries are indispensable in the historical process of developing new quality productivity, whether it is traditional industries, emerging industries or future industries.

　　"If you are sure, do it quickly."

　　From the central economic work conference in 2023, it was pointed out that "if you are sure, you should do it quickly"; At the deliberation site of the Jiangsu delegation of the National People’s Congress and the National People’s Congress, the general secretary stressed that "we must seize all favorable opportunities and make use of all favorable conditions, and work hard when we are sure, and bring all aspects of enthusiasm"; At the joint meeting of the Chinese People’s Political Consultative Conference, the general secretary pointed out that "don’t just criticize and dictate there, but really take action, and it is one thing to solve."

　　What runs through it is the spirit of down-to-earth and hard work.

　　This year is a crucial year to realize the objectives and tasks of the 14 th Five-Year Plan, and time waits for no one.

　　At present, the direction of China’s economic progress and breakthrough is very clear. The Supreme Leader’s General Secretary emphasizes "do it as soon as you see it" and "take real action", which is to call on everyone to seize the opportunity, be down-to-earth, strive to cope with the uncertainty of the changing situation with the certainty of their own work, and steadily achieve the established strategic goals.

　　"steadily improve the level of people’s livelihood security in development"

　　When attending the deliberation of the Jiangsu delegation last year, the General Secretary of the Supreme Leader emphasized that "the happiness and well-being of the people is the ultimate goal of promoting high-quality development". Facing the representatives of the Jiangsu delegation this year, the General Secretary pointed out that "we must adhere to the people-centered development thinking, steadily improve the level of people’s livelihood security in development, and guide and inspire the broad masses to create a happy life by their own hands".

　　The people-centered ruling concept is consistent and firm.

　　The important speech of the Supreme Leader General Secretary profoundly revealed that the construction of a strong country and national rejuvenation must closely rely on the people and draw wisdom and strength from them, and the ultimate goal is to do everything for the people.

　　"As long as we see that we are moving forward, we must maintain our concentration."

　　On the issue of ecological environment, the general secretary thought deeply and summed up his experience: "As long as we see that we are moving forward, we must maintain our strength."

　　Regarding the road of scientific and technological innovation, the General Secretary profoundly pointed out: "The Party Central Committee has formed a unified understanding on accelerating the self-reliance of high-level science and technology and developing new quality productivity, and is actively promoting it, but this will not happen for a while."

　　How to treat various problems encountered in development tests the historical vision and firm belief. Full of confidence and keeping our strength is of great guiding significance for us to understand the economic situation, cope with difficulties and challenges, and continue to advance along the right path.

　　Recently, the latest financial report released by RT Mart’s parent company Gaoxin Retail Co., Ltd. (06808.HK, Gaoxin Retail) shows that as of the first quarter of 2024, the company achieved revenue of 72.567 billion yuan in the latest fiscal year, down 13.3% year-on-year; During the year, the loss was 1.668 billion yuan, compared with the profit of 78 million yuan in the same period of last year. The loss was mainly caused by the impairment of the right to use assets, fixed assets and goodwill of negative cash flow stores, closed stores and stores to be closed.

　　It is understood that the main revenue sources of Gaoxin Retail are sales of goods, membership fees and rental income, among which the revenue from selling products through offline stores and online channels accounts for more than 95% of the total revenue. With the advent of the post-epidemic era, the supply guarantee business has contracted rapidly; On the other hand, consumption habits and market demand are constantly changing, consumers are gradually returning to rationality, and "hoarding goods" has become a thing of the past. "Although the offline passenger flow has picked up slightly, the decline in average passenger orders has led to a decline in the high number of offline revenues." The company said frankly in the financial report. With the shrinkage of stores, the number of members and tenants continues to decrease, and the income further declines.

　　Judging from the recent annual report and quarterly report published by various supermarket enterprises, the above problems are not the sufferings of Gaoxin Retail.

　　Declining performance and frequent store closures.

　　In 2023, 9 of the 13 supermarket listed companies experienced a decline in revenue, and more than half of them suffered losses, of which () they have suffered losses for three consecutive years, and Lianhua Supermarket’s net profit returned to its mother dropped sharply, with a drop of 273.71%. In the first quarter of 2024, the number of enterprises with declining revenue increased, while the net profit of () and China Shunkelong decreased by 619.18% and 125% respectively, making the life of traditional supermarkets more and more difficult.

　　In the current consumption environment, it is an indisputable fact that the traditional supermarket model no longer has obvious competitive advantages. In 2023, despite the gradual recovery of the national consumption environment, the overall performance of the FMCG market was poor, with the total omni-channel retail sales down by 0.5% compared with the previous year, and the retail sales in the offline market down by 3.6% compared with the previous year. It is worth noting that in 2023, the retail sales of department stores, convenience stores, specialty store and brand specialty stores in retail units above designated size increased by 8.8%, 7.5%, 4.9% and 4.5% respectively over the previous year, and only the retail sales of supermarkets decreased by 0.4% over the previous year. From 2020 to 2022, the total revenue of listed companies in Toushang Supermarket continued to decline.

　　Affected by the weak recovery of terminal consumption, the supermarket "closing tide" is still spreading. Take CR Vanguard as an example. Since its inception in 2024, the brand has closed more than 10 stores nationwide, including its high-end brand "Wanjia City" and boutique brand "Blt". From 2020 to 2022, CR Vanguard, as the industry’s leading brand, has closed more than 100 stores in succession, and this 40th anniversary enterprise has once again reached a crossroads.

　　Traditional supermarket brands such as Wal-Mart, Carrefour, RT Mart, Lianhua and Wumart have not been spared. According to incomplete business statistics, in the first quarter of 2024, about 1,200 supermarkets in China announced the closure of their stores, and the above brands were among them.

　　According to the research report of China Chain Store & Franchise Association, the traditional supermarket enterprises are facing three core challenges: the continuous loss of customers who arrive at the store, the gradual lack of commodity difference competition and the increasing operating cost of the store. Among them, the most significant change is that the characteristics of customer differentiation are becoming more and more prominent, and the younger generation of consumers have higher awareness and recognition of new brands such as Boxma Xiansheng; At the same time, the differentiation of products and channels in traditional supermarkets has narrowed significantly. "Promotion", "discount" and "membership price", including last year’s lively "moving mountains" and "tug-of-war", are essentially "price wars" for homogenized products. However, in the face of the strong industrial chain advantages of membership-based warehouse supermarket giants such as Sam and Kaikouke, the operating costs of traditional supermarkets are getting higher and higher, and their price advantages are not outstanding.

　　Under siege, traditional supermarkets are also actively looking for new ideas to solve problems.

　　Idea 1: Adjustment and optimization

　　At the beginning of May, the news about Henan Pangdonglai Trading Group’s "rescue" of Yonghui Supermarket Co., Ltd. (601933.SH, Yonghui Supermarket) triggered a heated public debate. As the "hand of God" of Shangchao and the helm of Fat East, can Yu Donglai really help Yonghui, which has been troubled by the decline in performance for a long time? The answer will be announced in June.

　　According to relevant media reports, Fat Donglai’s assistance in this transformation involves Yonghui Supermarket Zhengzhou Hanhai Beijindian Store and Xinxiang Baolong Plaza Store. The transformation of the two stores will be started at the beginning of June and the end of June respectively. After the transformation, Yonghui’s existing supply chain system will be the main store, and Fat Donglai will make a structural supplement, and the cooked food series and baking series that Fat Donglai sells well will be introduced with full reference to the commodity structure of Fat Donglai.

　　Before Fat Donglai intervened in the adjustment and reform, Yonghui Supermarket had started the road of adjustment and optimization. For example, add baking, pastry, cooked food and other processing and catering areas in some stores to expand diversified consumption scenarios; In some stores, large packages of snack food and large-capacity laundry detergent are introduced to meet the shopping needs of family consumers. At the beginning of this year, Yonghui Supermarket opened the first "customized store" in China-Yunnan flagship store, focusing on the multi-level commodity structure of "global+national+local", and introduced local specialties such as Yunnan ham, dried beef and gastrodia elata for the first time.

　　In fact, compared with Yonghui supermarkets all over the country, Fat Donglai, who lives in a corner, can’t be compared with it in terms of performance, scale and influence. According to the list of "TOP100 Chain Stores in China in 2022" issued by China Chain Store & Franchise Association, Yonghui Supermarket ranks second in the chain supermarket industry, second only to Wal-Mart, and is "far ahead" of other domestic brands, and the company’s performance in its glorious period is close to 100 billion. However, since 2021, the company has suffered losses for three consecutive years, with a cumulative amount of 8 billion yuan. Although the company’s losses were further narrowed in 2023, the company’s revenue still dropped significantly in the first quarter of this year.

　　At the same time, Fat Donglai has gradually gained advantages in store planning and management, employee welfare and customer service, and in recent years, it has become stronger and stronger in terms of quality-price ratio and influence. What is even more rare is that Fat Donglai is willing to share his successful experience with his peers in trouble. It is reported that since 2023, Fat Donglai has extended a helping hand to more than 10 retail enterprises with operational difficulties.

　　Among them, BBK Commercial Chain Co., Ltd. (002251.SZ, ()) is also facing the decline of performance year after year and losses for three consecutive years. Unlike Yonghui Supermarket, which is in the first echelon of the industry, BBK has reached the edge of life and death. In 2023, BBK closed 113 stores with no hope of turning losses; On October 26th of the same year, the Intermediate People’s Court of Xiangtan City, Hunan Province ruled that BBK went bankrupt and reorganized due to its inability to pay off the debts due and its obvious lack of solvency. On October 31st, BBK shares were warned of delisting risk since the resumption of trading, and its share price continued to fall.

　　At this time, Fat Donglai appeared, and several poorly managed stores under BBK were optimized and upgraded in all directions from the aspects of layout, shopping environment, commodity structure, quality and price, and personnel service. BBK made it clear in the annual report that in 2024, with the help of Fat Donglai, the company will reshape corporate culture, management system, store operation and supply chain, and strive to create a sincere, beautiful and loving corporate culture and high-quality stores, and rebuild supermarkets and department stores with reference to the standard of "Fat Donglai is local, and local Fat Donglai is local".

　　Is the adjustment really effective? Recently, BBK released a set of data: after more than 20 days of adjustment and reform, BBK Meixihu Supermarket has reached a peak of 1.4 million yuan from the original daily sales of 150,000 yuan and an average daily passenger flow of 2,000 people, and the store passenger flow has exceeded 15,000 people; After the adjustment, Jiuhua Store of BBK Supermarket sold 1.64 million yuan on the first day of opening. This adjustment and reform eliminated 70% of low-quality and low-price goods from the shelves. After the adjustment and supplement are in place, its product structure will reach 90% of that of Pangdonglai. At the same time, BBK Supermarket also announced that all stores in Hunan stopped all marketing activities and lowered the retail price of more than 3,000 commodities again. Judging from the news released by BBK official micro recently, it seems that "practicing the concept of coming from the fat east" has become the belief of the company, and the performance of turning losses into profits in the first quarter has also made the company see hope.

　　In addition to consulting the industry’s "military division", other supermarkets are also accelerating the adjustment and optimization of stores. At the end of 2023, in order to welcome the 40th anniversary of the company’s establishment, CR Vanguard launched eight cities and nine stores, which will be renewed and upgraded. CR Vanguard said that the company is implementing the upgrading measures of some stores in a planned way. In the next one to two years, the stores will continue to upgrade, and the integrated urban agglomeration of Beijing-Tianjin-Hebei, Greater Bay Area, Yangtze River Delta and Pearl River Delta will be clearly included in the follow-up development focus. The core of this upgrading plan is omni-channel layout and integrated operation, focusing on the value of single customers, focusing on accurate marketing of members and enhancing the consumer experience.

　　Idea 2: Transformation and upgrading

　　Yonghui Supermarket and BBK gradually reversed the trend in the process of adjustment and optimization. The loss of the former narrowed, while the latter turned losses into profits, and the "self-help" measures were effective in stages. On the basis of adjustment and optimization, can we take greater steps? Many brands tend to transform and upgrade on a large scale. CR Vanguard set its sights on the purchasing power of high-net-worth customers, and upgraded some stores that did not meet the new strategic positioning to "Olé" and "BLT" high-end supermarkets, and at the same time broadened the service radius of stores to meet the upgrading needs of consumers in business circles. In fact, CR Vanguard has been deeply involved in the field of boutique supermarkets for many years. This year marks the 20th anniversary of the establishment of the "Olé" brand, and the number of stores in China has exceeded 120. Olé’ s own brand has been extended to fruits and vegetables, aquatic products, meat, eggs and milk, baby care and household items, and nearly 500 products have been launched. However, as a sub-brand, "Blt" is losing momentum because its brand positioning and product structure are not "differentiated" from "Olé".

　　Compared with the layout in advance in CR Vanguard, more brands choose overweight boutique supermarkets in order to adapt to the changes in market structure, business model and consumption habits. In May 2023, the ——Green&Health Jade Bird Store, the first "big community+small warehouse" model store of Hangzhou Lianhua Chinese businessmen, opened; In November of the same year, the innovative format of Lianhua Supermarket-Century Lianhua CityLife high-end boutique supermarket Shanghai Gubei Store opened. Prior to this, Box Horse’s first high-end supermarket, Premier Black Label Store, also chose to open in Shanghai. Compared with warehouse-based member stores with relatively remote locations, most boutique supermarkets in the core business district are more likely to attract customers to the stores for consumption.

　　But does large traffic mean high customer orders? But not really. According to the real feelings of Yinshi Finance’s recent visit to boutique supermarkets, most boutique supermarkets have the actual situation of "more people loitering than buying" and "higher product unit price but lower transaction amount". Different consumer groups have obvious differences in their cognition of boutique supermarkets, and boutique supermarkets are not the first choice for most consumers. What determines the "admission" and "farewell" of boutique supermarkets? )

　　In order to improve the guest list and efficiency, in addition to boutique supermarkets, in the eyes of traditional supermarket brands, warehouse membership stores are also a new way. Heading for member stores is a new way for Gaoxin Retail to find for itself. In the recent fiscal year, Gaoxin Retail has opened 6 RT Mart (hypermarkets), 14 RT Mart Super (medium-sized supermarkets) and 3 M-member stores, with a total of 472 hypermarkets and 32 medium-sized supermarkets. In April 2023, the first M-member store opened in Yangzhou, Jiangsu Province. During the reporting period, the number of paid members has exceeded 60,000, and the total number of members has exceeded 110,000. As of March 31, 2024, the cumulative number of paid members in China was about 140,000, and the total number of members was nearly 240,000. The company has started the project of 4 M member stores, and plans to open 15 member stores within three years. However, as far as the scale and structure of the company’s existing stores are concerned, member stores still cannot become the main revenue force in the short term.

　　According to the data released by Ai Media Consulting, from 2012 to 2022, the scale of China warehousing membership supermarket industry has always remained above 20 billion yuan. In 2023, the scale of the industry reached 36.41 billion yuan, and it is expected to approach 40 billion yuan in 2024, which has great development space. In the field of warehouse-style member stores, Sam, Box Horse and Metro have accumulated a number of loyal users, and the head effect is gradually emerging. Other brands need to have more prominent supply chain advantages or form distinctive brand characteristics to get a share, and the competition will be further intensified. Take Nanjing as an example. At present, there are seven warehouse membership supermarkets such as Metro, Sam Member Store, Box Horse X Member Store and M Member Store, and Costco will be opened at the end of May. In the future, there will be more and more high-energy cities with multiple brand warehouse membership supermarkets like Nanjing.

　　The competition between the two new tracks is so fierce, is there any other way to solve the problem? Then try them all. In 2023, () chose to "bet" on new formats. The company successively launched new brands such as Yueji Snack Shop and Haohuixing Discount Store, and focused on promoting franchise business. In the first quarter of 2024, Jiajiayue opened 12 directly operated stores and added 8 franchised stores. Among them, snack shops, discount stores, convenience stores and other formats realized revenue of 53.5442 million yuan, up 46.66% year-on-year, and the growth momentum was obviously better than that of general supermarkets, rural supermarkets and other formats. At the same time, Jiajiayue chose to avoid the high-speed cities where high-quality supermarkets and warehouse member stores gather, and focused on developing markets in Shandong and its surrounding Inner Mongolia, Beijing, Hebei, northern Anhui and northern Jiangsu. Through the network layout of dense areas, urban and rural integration and multi-formats, it created a "quarter-hour" convenient life circle in sinking communities and township markets, and at the same time, it relied on stores to carry out online services such as home service and pick-up at stores, and also took over the business of "community group buying"

　　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.

　　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.

　　Small anti-slip coup: sanding

　　In case of rain, snow and freezing weather, in order to prevent the wheels from idling and slipping, the driver will start the sanding system according to the actual situation in operation. In addition, when the brake control system of the EMU independently judges that the wheelset is idling or sliding, it will automatically sand.

　　Under the action of compressed air, the sand in the sand box of the EMU is scattered on the rail surface at the front end of the wheel running direction along the sand pipe. When the wheel runs over the sand, the friction between the wheel and the rail will increase, thus effectively solving the wheel slip problem and ensuring the EMU to stop within the specified braking distance.

　　Since the beginning of winter, China Railway Beijing Bureau Group Co., Ltd. has kept a close eye on the source management and strengthened the maintenance of EMU.

　　The anti-skid sand used by EMU is not ordinary "sand", but Shi Ying particles made of quartz stone by crushing. When the EMU is put into storage for maintenance, the ground crew should add sand to the cars with less than 50% sand.

　　EMU maintenance personnel will also focus on the inspection of key parts such as sand pipes in combination with the seasonal characteristics in winter.

　　When the locomotive is running in snowy weather, it is also necessary to carry out sanding operation.. When the locomotive and rolling stock are put into storage for servicing operation, the sanding workers should fill the locomotive in storage with machine sand. At the same time, they also need to regularly maintain, repair and clean the locomotive wheels, and check and replace the spring devices to ensure the locomotive running in good condition.

　　Clear the snow in time

　　After the snowfall, in order to ensure the safe operation of the train, the railway department promptly cleared the snow in key parts of the railway line, organized personnel to quickly carry out hot standby of snow removal machines, and cleared the snow and ice accumulation in sections and turnouts with slopes at the first time according to the changes of snow conditions and equipment conditions, so as to restore the normal state of the railway line and ensure the safe and smooth railway transportation.

　　The railway department pays close attention to the equipment changes, especially in areas with high cold and heavy snowfall, and sends special personnel to patrol the equipment continuously and clear the snow at the turnout to ensure the equipment is in good condition and the line transportation safety.

　　Nowadays, many high-speed rail lines are equipped with high-tech automatic snow melting devices, which can assist manual snow removal and deicing of turnouts.

　　Anti-skid is not just "footwork"

　　When there is freezing rain, snow melting and freezing weather, the key parts such as railway tunnels, tunnel entrances and overpasses are easy to freeze. The railway departments take off-line inspections, additional inspections, fixed-point observations, etc. to increase the inspection of key places and clean up icicles near the catenary in time; At the same time, strengthen emergency drills and training around the ice-breaking operation process and safety precautions to ensure personal and driving safety.
