Xinhua News Agency, Beijing, January 20thQuestion: How did the market react on the first day when the mobile phone was opened?

Xinhua News Agency reporters Tang Ningning, Li Qianwei and Gong Liankang

On January 20th, the first day of the implementation of new subsidies for mobile phones, tablets and smart watches (bracelets) in China. How is the market? What is the consumer response? The reporter visited the first batch of online areas such as Beijing, Hubei and Sichuan for a first-line visit.

"State Subsidy 15%" and "Mobile phone single product is the highest subsidy to 500 yuan"-it is particularly eye-catching to open the national subsidy service window for digital products such as mobile phones in JD.COM. "I have been making up for the country for a long time, just waiting for the discount to buy a mobile phone." On the morning of the 20th, Mr. Li, a Beijing citizen, couldn’t wait to place an order for a Xiaomi mobile phone with the national subsidy.

He also showed a screenshot of the interface for receiving subsidies, which only takes two steps: go to the "Jingtong" applet to receive and copy the qualification code, and enjoy the subsidies after the platform is bound. "The whole process takes a few minutes to operate, which is very convenient."

The reporter noticed that in order to let consumers know more about how to get the national subsidy, the platforms have launched online guidelines, and the process is clear at a glance. The operation steps are relatively simplified, and automatic reading and intelligent identification greatly reduce the manual entry and repeated entry of information.

The person in charge of JD.COM told the reporter that on the first day of the opening of mobile phone national compensation, the activities of national compensation in Beijing, Hubei, Jiangsu, Zhejiang and Shaanxi have been fully launched. The data shows that as of 12 noon on the 20th, the sales volume of mobile phone products in the online region of China increased by 200% month-on-month, the growth rate of flat panels by 300%, and the growth rate of smart children’s watches by 100%. Mobile phones with prices ranging from 3,000 yuan to 4,000 yuan are the best sellers.

At 1 o’clock in the morning on the 20th, a vivo mobile phone was delivered by SF Express to Mr. Guan in Xiaoshan District, Hangzhou, becoming the first order for Tmall mobile phones. From now on, Zhejiang and Jiangsu have started state subsidies for digital products such as mobile phones in Tmall, which can be superimposed on the platform for up to 24 interest-free rights. Guangdong, Shanghai, Hainan, Shanxi, Jilin, Fujian and other regions have been launched one after another.

The online platform is "hot" and the offline stores are "steaming".

Although it is a working day, at 9 o’clock in the morning, a large wave of customers have gathered in the digital products area of Suning.cn Guangwai Store in Xicheng District, Beijing. Everyone is waiting for the national supplement to go online on time at 10 o’clock and win the favorite products that are optimistic in advance.

"This national subsidy activity is not limited to brands or models. As long as it is a digital product such as a mobile phone with a final price of no more than 6,000 yuan, it can enjoy subsidies." Shan Jie, deputy manager of Suning Guangwai Store, told the reporter that within more than half an hour after the opening of the national subsidy that morning, the store sold 20 or 30 mobile phones, which was several times higher than that of the previous weekend.

In Hubei, the national subsidy activities are in full swing. In a mobile phone store in Jindi Square, Hongshan District, Wuhan, consumers who come to buy mobile phones, tablets and smart wearable devices are in an endless stream. The on-site shopping guide said: "The passenger flow is about twice as much as usual, all of which are made up for the country."

"The screen of the mobile phone used now is too small, and I’ve always wanted to change a folding screen. This wave of national compensation is quite cost-effective, just before the Spring Festival. " Wang Zixiao, a sophomore who just took a winter vacation, took a fancy to a folding screen mobile phone. He also calculated the account for the reporter: the original price of the mobile phone is 5,788 yuan, and he can enjoy 500 yuan’s national subsidy, and then a wireless charging set worth more than 200 yuan is given, which can be much cheaper if the discount is superimposed.

It is a major feature of this purchase of new subsidies that you don’t have to pay the old ones and make a reduction.

"The subsidy rules are very transparent, there is no routine, and 500 yuan is directly reduced when paying." Wang Zixiao and many consumers have repeatedly praised the subsidy method of paying the reduction. The reporter learned that whether it is an online platform or an offline physical store, consumers can enjoy the benefits of subsidies in the first time by paying a reduction.

Can the production and supply guarantee keep up with the implementation of the new subsidy nationwide?

"From January to November 2024, China’s mobile phone production was 1.504 billion units, and 393 new models of mobile phones were listed, and the product pedigree of leading enterprises was rich." At a special news conference held by the Ministry of Commerce a few days ago, Wenli Xu, deputy director of the Department of Electronic Information of the Ministry of Industry and Information Technology, said that China is the world’s largest manufacturing center for consumer electronic products such as mobile phones and tablets, and global mainstream brands and OEM enterprises have large manufacturing bases in China, so China’s manufacturing capacity can meet the demand of "machine change tide".

Specific to major shopping malls and brand stores around the country, the landing work of undertaking national subsidies has "run" ahead of schedule.

During the visit, Guo Linhai, the manager of Xiaomi Home Store in Chengdu Kaide Tianfu Shopping Mall, told the reporter that in order to let customers buy the existing machine as soon as possible, the store prepared the goods early, and the stock of mobile phones and tablets was twice as much as usual. Song Yange, deputy manager of the user operation of JD.COM Super Experience Store in Chongqing Liangjiang New District, said that in order to meet this wave of large traffic, there are currently more than 5,000 mobile phones in the store, and more than 1,000 tablets and smart wearable products are stocked …

Next, the subsidies for purchasing new digital products such as mobile phones will be launched one after another all over the country. How to ensure the safety of funds? How to ensure that the transaction is true and effective and truly benefits consumers?

Li Jialu, director of the Circulation Development Department of the Ministry of Commerce, said that the coordination between the central and local governments will be strengthened, and information on subsidy application, transaction payment and fund write-off will be cross-checked and compared by technical means to ensure the authenticity of buyers’ identity information and transaction information. "We will do a good job in big data analysis, strengthen monitoring, forecasting and early warning for false transactions, one machine selling more, and a large number of goods, and strictly guard against risks."

CCTV News:On August 1st, 53 new confirmed cases in COVID-19 were reported, including 30 cases in Jiangsu, 12 cases in Henan, 4 cases in Hunan, 3 cases in Yunnan, and 1 case in Fujian, Shandong, Hubei and Ningxia. Recently, the epidemic originating from Nanjing Lukou Airport has spread to many places in China. In addition, there are epidemics in Henan, Fujian and other places, and all localities are constantly upgrading their control measures while conducting emergency screening.

Strict access to Beijing management scenic spots is open according to 60% flow restriction.

According to the Beijing Center for Disease Control and Prevention, from 0: 00 to 16: 00 on August 1st, two confirmed cases of local COVID-19 and one asymptomatic infected person were newly added in Beijing, all of whom came from the same family in Zhangjiajie, Hunan Province. Beijing held a press conference on August 1st, advising the public to minimize their activities out of Beijing, including traveling to Beijing, and explicitly demanding that parks, scenic spots and historical sites be opened according to 60% current restriction.

Zhangjiajie, Hunan: Strengthening the management of the community, in principle, no going out.

Tourism professionals, a new confirmed case in Xiangxi Autonomous Prefecture of Hunan Province on July 31st, was a close contact of five confirmed cases in Huai ‘an Tourism Group of Jiangsu Province on July 26th. At present, many secret connections of the tour group have been diagnosed.

According to official reports, Zhang Moumou, a newly confirmed case in Yinchuan yesterday, is a close contact of a confirmed case in Chengdu. According to Hunan’s announcement today, Zhang Moumou is the director of the program "Xiang Yu Tao Hua Yuan" and has worked in nine performances. The 777 spectators who watched these 9 performances are currently at high risk.

Zhangjiajie issued a notice on August 1 to strengthen the management of the community. In principle, it is not allowed to go out. At present, all nucleic acid detection points in the city have set up special channels for emergency free nucleic acid detection tourists. Visitors need to complete three nucleic acid tests before leaving Zhangjiajie. COVID-19 vaccination for people aged 15 to 17 was launched in Hunan today.

Sichuan: Of the 10 cases, 9 were homologous to the Nanjing epidemic strain.

Recently, there were 8 confirmed cases in COVID-19 and 2 asymptomatic infections in Mianyang, Luzhou, Chengdu and Yibin in Sichuan. As of July 31st, the province has designated six medium-risk zones.

Yangzhou, Jiangsu: Adjust the risk level and suspend domestic flights in and out of Yangzhou.

On July 31st, Yangzhou, Jiangsu Province, 12 local confirmed cases were added. In this round of epidemic, 28 local confirmed cases were reported. Since August 1st, Yangzhou City has added eight medium-risk areas, and many other areas have been adjusted from medium-risk areas to high-risk areas.

In addition, since August 1, Yangzhou has completely suspended domestic flights to and from Yangzhou. Passengers leaving Yangzhou through the railway station under the jurisdiction of Yangzhou (excluding transit) must provide negative proof of nucleic acid test and green code of health code within 48 hours. The entrances and exits of 20 expressway toll stations around Yangzhou are closed. The bus, taxi, network car and ride services in the main city of Yangzhou were suspended.

Zhengzhou, Henan Province: Closed-loop management of hospitals involved in the epidemic caused by Delta strain.

On July 31st, there were 12 new confirmed cases in Henan, all in Zhengzhou. Zhengzhou CDC introduced on the 31st that the epidemic was caused by Covid-19 Delta strain, which mainly occurred in the hospital and showed a state of local spread. At present, Zhengzhou Sixth People’s Hospital has implemented closed-loop management and stopped diagnosis and treatment. Zhengzhou city is carrying out all-staff nucleic acid testing to ensure that all inspections should be completed.

According to the development characteristics of the current epidemic, Feng Zijian, a researcher at China CDC, said that the epidemic was first imported through Nanjing Lukou Airport and further spread. It is preliminarily judged that the first case in Zhangjiajie is related to the epidemic situation in Nanjing Lukou Airport, and the cases or infected people spread to Zhangjiajie, Hunan Province, and then infected others through tourist attractions and large-scale performances, which led to further virus spread and spread.

eight Risk grade determination

From high to low, the risk level of experimental safety is divided into major risk (level 1), major risk (level 2), general risk (level 3) andLow risk (level 4) four levels.

Level 1 (red): significant risk. It is extremely dangerous and cannot be carried out.In the experiment, control measures should be supplemented immediately in order to reduce the risk level, and regular inspection, measurement and evaluation should be carried out;

Level 2 (orange): greater risk. High risk, immediate rectification, supplementary control measures, regular inspection, measurement and evaluation;

Level 3 (yellow): general risk. Significant danger, need to be rectified, establish goals, establish operating procedures, and strengthen training and communication;

Level 4 (blue): low risk.lowerDanger, need to pay attention to, improve the control measures in time.

The conclusions obtained by different risk analysis and evaluation methods may be different, so the one with the highest risk level should be selected as the risk level of the project.

Experiments and experimental projects adopt a safety risk classification and classification management mechanism. Effective safety prevention and control measures and emergency plans should be formulated and strictly implemented for experiments and experimental projects with risk level above level 3, and experiments can be carried out only after being examined and confirmed by the unit, and relevant materials should be filed.

According to the relevant national and industrial regulations, norms and standards, the classification of experiments and experimental projects and the division of risk levels are adjusted in a timely manner (see AnnexC）。

 Risk assessment method

 According to the characteristics of experiments and experimental projects, comprehensive analysis, qualitative and quantitative evaluation are generally carried out by using hazard analysis method of working conditions, pre-hazard analysis method, analogy method and checklist analysis method.

(1)Hazard analysis method (LEC)

Hazard analysis method for working conditions (Graham–Ginny method is a semi-quantitative risk assessment method for workers working in occupational hazardous environment. The evaluation principle is: the quantitative risk value of operating conditions (D) depends on three factors, (one) the possibility of an accident (L）； (2) Frequency of exposure of workers to dangerous working environment (E）； (three) The severity of possible consequences in the event of an accident (C）。 Represented by a simplified formula is:D=L×E×C

amongDThe greater the value, the greater the danger of the operation. Danger of working conditionsDSee table for the classification of values.2.

L、E、CSee table for the range of the three factors.2, tablethree, tablefour.

table2   L-Accident possibility score

table3   E-Frequency score of exposure to dangerous environment

table4   C-Consequence score caused by accident

 

(2) Pre-hazard analysisway

Pre-hazard analysis (PHA) is a system safety analysis method that makes a macro and general analysis of various risk factors (categories and distributions), occurrence conditions and possible consequences of accidents in the system before an activity (such as an experiment). Its purpose is to find the potential risk factors of the system at an early stage, determine the risk level of the system, and put forward corresponding preventive measures to prevent these risk factors from developing into accidents and avoid thoughtlessness.The losses caused are qualitative evaluation. That is to say, discuss, analyze and determine the dangerous and harmful factors existing in the system, their triggering conditions and phenomena, the causes and events that caused the accident, the accident types, the accident consequences and the danger level, and put forward the safety precautions that should be taken.

(one) Pre-hazard analysis step

① Fully investigate the purpose, process, operating conditions and surrounding environment of the experiment;

② Collect past experience and accidents in similar experiments, judge whether similar situations will occur in the objects to be analyzed, and find out the dangers that can cause material losses and personal injuries;

③ Determine the hazard source according to experience, technical diagnosis and other methods;

④ Identify the conditions of dangerous transformation and study the trigger conditions of dangerous factors transforming into accidents;

⑤ Carry out risk classification, determine the degree of risk, and find out the dangerous sources that should be controlled emphatically;

⑥ Formulate risk prevention measures.

(2) risk classification

PHAThe result of the analysis is expressed by the risk grade. Danger can be divided into four grades, as shown in table.five.

tablefive  Hazard classification table

(three) evaluation results

Pre-risk assessment analysis adopts the following tabular form (Tablesix) Submit the results.

table6  Hazard pre-analysis table (sample table)

 

(four) analysis summary

Through the pre-risk assessment and analysis, the main risks and risk grades of experiments or experimental projects are obtained.

For all kinds of possible dangers and harmful factors, preliminary preventive countermeasures and measures are put forward one by one in the risk pre-analysis table.

(3) analogy method

Through the safety investigation of the same or similar projects as the experimental projects to be evaluated, and the analysis of relevant experimental documents and technical data, it is proposed to evaluate the types and degree of hazards and harmful factors of the experimental projects by analogy, assess the possible hazards and harmful factors, and predict the control effect of the proposed safety protection measures.

(4) Checklist analysis method

According to the national laws, regulations, technical specifications and standards related to occupational safety and health, as well as operating procedures and production safety accident cases, through detailed analysis and research on the experimental items to be evaluated, the inspection units, parts, items, contents and requirements are listed, and a table is compiled to check the compliance one by one to determine the safety problems, defects and potential hazards of the experimental items to be evaluated.

Attachment:Notice on printing and distributing guidelines for risk assessment of scientific experiments

　　Promote the construction of high-standard farmland and improve grain production capacity; Building a modern agricultural industrial park and extending the agricultural industrial chain … … Recently, focusing on the shortcomings of agriculture and rural areas, all localities have made every effort to promote the construction of agricultural and rural infrastructure projects.

　　A new batch of projects will also be accelerated. The Ministry of Agriculture and Rural Affairs and other departments have recently issued a clear document. From now until the end of the year, we will focus on the construction of projects such as short-board irrigation and water conservancy facilities, modern facility agriculture and cold chain logistics facilities for agricultural products storage and preservation, and start a number of new projects to ensure the formation of physical workload as soon as possible. Effective as soon as possible, laying a solid foundation for stabilizing the economic market.

　　Agricultural and rural infrastructure construction was accelerated.

　　In the autumn harvest season, on the mountain of Yongjin Village, Jiaxinzi Town, Baoqing County, Shuangyashan City, Heilongjiang Province, high-standard farmland complements the surrounding mountains. Lin Haifei, a local villager, told reporters that the soybean planted by the cooperative this year has increased production compared with last year and will usher in a bumper harvest. "This year’s bumper harvest is not only because of the good years, but also because of high-standard farmland." Lin Haifei said.

　　In recent years, the construction of high-standard farmland with centralized contiguous areas, supporting facilities and high and stable yield has become an important measure to improve grain production capacity and ensure food security. As the largest grain-producing province in China, Heilongjiang Province plans to build 11 million mu of high-standard farmland in 2022.

　　Recently, the Heilongjiang Provincial Department of Agriculture and Rural Affairs held a meeting to promote the construction of high-standard farmland in the whole province, which pointed out that we should pay close attention to the golden construction period of the current high-standard farmland construction, ensure the completion of the annual tasks as scheduled, and promote new projects to form more physical workload and effective investment. The unfinished carry-over tasks should be completed by the end of October.

　　In Ningxia, the capital construction of farmland water conservancy in autumn and winter has completed 50% of the total annual task, with an accumulated investment of nearly 4 billion yuan. Among them, 798,500 mu of high-standard farmland has been completed, accounting for 84% of the total task.

　　Building a modern agricultural industrial park is a key measure to develop modern agriculture and extend the agricultural industrial chain. On October 14th, Yufeng cold chain logistics warehousing project, one of the national modern agricultural industrial park projects in Qingcheng District, Guangdong Province, was started, with a total investment of 600 million yuan. It will build a smart agricultural industrial park integrating cold chain warehousing, logistics system, trading market and poultry slaughtering and processing. In Sichuan, the construction of 26 projects in chuanshan district Modern Agricultural Industrial Park is also struggling to sprint the annual goals and tasks.

　　"At present, the construction of related projects in the agricultural and rural areas is being implemented, and the effective investment and policy effects in agriculture and rural areas are continuously expanded to effectively promote the development of agriculture and rural areas." Guo Pei, a professor at the School of Economics and Management of China Agricultural University, said.

　　A new batch of key projects will be launched.

　　The reporter learned that focusing on the shortcomings of agricultural and rural infrastructure, a new batch of projects is accelerating.

　　The the State Council executive meeting held on September 26th proposed to speed up the construction of agricultural and rural infrastructure projects under construction, start a number of new projects, and complete the investment of more than 300 billion yuan this year.

　　Recently, the Ministry of Agriculture and Rural Affairs, the Ministry of Water Resources and other eight departments jointly issued a document to make specific arrangements for expanding the current investment in agricultural and rural infrastructure construction, demanding that from now until the end of the year, we should focus on the construction, renovation and upgrading of irrigation areas and other water conservancy facilities, the construction of short-board farmland water conservancy facilities, modern facility agriculture and cold chain logistics facilities for agricultural products storage and preservation, speed up the implementation progress of projects under construction, and start a number of new projects to ensure that physical workload is formed as soon as possible and results are achieved as soon as possible.

　　Previously, the Ministry of Agriculture and Rural Affairs required all localities to focus on planning and storing a number of new major projects in key areas such as high-standard farmland, modern facility agriculture and cold chain logistics of agricultural products, and speed up preliminary work such as project approval, approval and filing.

　　"As a basic industry, agriculture directly or indirectly affects the entire national economy, and the economy is stable when agriculture is stable." Guo Pei said that the promotion of key projects in agriculture and rural areas will increase investment in agriculture and rural areas and play an important role in stabilizing the economy. At the same time, in order to comprehensively promote rural revitalization and accelerate the modernization of agriculture and rural areas, it is necessary to further focus on key tasks such as stabilizing grain production and optimizing rural characteristic industries to promote the transformation and upgrading of agricultural and rural economies.

　　He said that we should focus on shortcomings and weaknesses, encourage major grain producing areas and advantageous areas of characteristic agricultural products to develop agricultural product processing industries, and improve the level of mechanization and standardization of the industry; Encourage qualified places to build cold chain distribution centers of origin, build logistics nodes of agricultural products, and develop new circulation formats of production and marketing docking.

　　Guide multi-channel capital to invest in agriculture and rural areas

　　With the acceleration of project construction, many parties have also increased their support to further guide social capital and financial capital to invest in key areas of agriculture and rural areas.

　　"Agricultural infrastructure construction usually faces some difficulties and challenges in investment and financing." Fan Ruoying, a researcher at China Bank Research Institute, said that the lack of marketization in the operation of agricultural and rural infrastructure projects has led to insufficient attraction to commercial funds and social funds; Agricultural and rural infrastructure projects still have the characteristics of long cycle and high cost, and the matching degree with social funds is not high; In addition, China’s current overall agricultural industrial efficiency is not high, and the expected income of the project is low, which also affects the project investment and financing to some extent.

　　In this regard, a series of arrangements have been launched to promote the linkage between government investment and financial credit investment and loan, and to encourage social capital to cooperate in construction and operation.

　　The reporter learned from the Ministry of Agriculture and Rural Affairs on October 18 that the Ministry of Agriculture and Rural Affairs, the National Rural Revitalization Bureau and the China Development Bank recently signed a strategic cooperation agreement on development financial services for rural revitalization, and put forward specific plans to support the construction of high-standard farmland and the development of rural industries, and jointly explore the medium and long-term credit model for agricultural and rural infrastructure.

　　The "Work Plan on Expanding Current Investment in Agricultural and Rural Infrastructure Construction" released recently also proposes to promote the linkage between government investment and financial credit investment and loan in fund raising; In terms of operation mode, social capital is encouraged to cooperate in the construction and operation of agricultural and rural infrastructure projects with high marketization, such as facility agriculture and cold chain logistics.

　　Local governments have also carried out a series of innovative practices. For example, in recent years, Guangdong Province has supported modern agricultural demonstration zones to guide more financial capital to invest in the agricultural sector in the form of "government and bank insurance" and "investment and loan supplement". By the end of April 2022, the actual total investment of 191 provincial-level agricultural industrial parks in eastern Guangdong, western Guangdong and northern Guangdong was 39.9 billion yuan, and the proportion of provincial-level financial funds inciting local and social funds reached 1∶5.06.

　　Fan Ruoying said that innovative practices such as government investment and financial credit investment and loan linkage can better solve the problem of investment and financing difficulties in agricultural and rural infrastructure construction projects, which is not only conducive to better mobilizing the investment enthusiasm of commercial funds, supplementing project funds, but also conducive to innovative project financial products and services, strengthening the marketization of projects, achieving win-win goals, and promoting agricultural and rural construction projects to be effective as soon as possible.

　　Recently, coconut water frequently boarded hot searches, and topics such as # Drinking pre-opened coconut into the emergency room # caused heated discussion among netizens. Some netizens reported that after drinking the pre-opened coconut water, they felt sick, vomited and had a high fever.

　　Many people say that this symptom is not unique: "My friend vomited after drinking the spoiled coconut water", "After drinking it, his head was particularly painful and his stomach turned upside down" and "the shelf life of coconut is very short, and the pre-opening is very unsanitary".

　　Coconut water is undoubtedly a cool and thirst-quenching product in summer. Then, can you buy pre-opened coconuts? The reporter conducted an investigation.

　　Why is pre-opened coconut water "poisonous"?

　　Pre-opened coconut refers to coconut that has been cut or drilled to facilitate drinking coconut juice. Because of its convenience, pre-opened coconut water is very popular with consumers, but coconut is easily contaminated by bacteria after pre-opening.

　　First of all, coconut may be polluted by unclean equipment or tools during cutting and processing;

　　Secondly, if the coconut is not sealed and refrigerated in time after opening, and the summer weather is hot, it is likely to lead to bacterial growth;

　　Thirdly, due to improper handling during transportation or storage, if the whole cold chain is not maintained or the storage time is too long, bacteria may multiply and lead to food poisoning.

　　A large number of staphylococcus aureus will make coconut deteriorate, which will lead to nausea, vomiting, abdominal pain, diarrhea and other symptoms after eating it by mistake; Pseudomonas cocoanum is more deadly, and spoiled coconuts stored for a long time may breed Pseudomonas cocoanum and produce a special toxin — — Rice yeast acid is harmful to important organs such as liver, kidney and heart. Horribly, even if heated to 100℃, it can’t destroy its toxicity. At present, there is no specific medicine in clinic, and the mortality rate of poisoning cases is as high as 50%. If you have suspicious symptoms, you should see a doctor immediately.

　　There is chaos in the pre-opening coconut market.

　　The reporter visited and found that at present, the pre-opened coconuts on the market have branded packaging products, and some supermarkets open their own packaging, which are sold in major supermarkets and fruit shops. But without exception, its packaging only marked the date of listing and packaging, but did not mark the shelf life.

　　At present, most of the pre-opened coconuts on the market only indicate the market date and packaging date, but not the shelf life.

　　The reporter asked how long is the shelf life of the pre-opened coconut? How to judge whether the pre-opened coconut has expired?

　　Many supermarket clerks used excuses such as "it doesn’t expire as long as it’s on sale" and "if it’s not fresh, we’ll take it off the shelf", but they couldn’t answer the reporter’s question directly.

　　Some shop assistants recommended a higher-priced "coconut egg" to the reporter, that is, a coconut with half its skin peeled. The shop assistant said that the "coconut egg" had no opening, and it was more hygienic to poke the coconut meat with a straw. The reporter saw that some "coconut eggs" were indeed marked with the date of production and shelf life (3 days), which looked more formal than pre-opened coconuts, but lacked the date of listing. The clerk couldn’t answer the question "Why are the labels of pre-packaged coconut products different?".

　　Some "coconut eggs" products are marked with the date of production and shelf life, but the date of listing is missing.

　　Fresh coconuts can be drunk directly after opening, but consumers should pay attention to pre-opened coconuts. It is recommended to choose a reliable merchant when buying pre-opened coconuts, check whether the appearance of coconuts is intact, and check the freshness of coconuts. It is best to pour coconut water out before drinking to distinguish whether it has deteriorated.

　　Supervision is still in a gray area.

　　Call for corresponding measures as soon as possible.

　　How to buy a safe pre-opened coconut? Is there anyone to supervise?

　　Li Shuguang, a professor at Fudan University School of Public Health, said that the pre-opened coconut does not belong to prepackaged foods yet, so there is no mandatory implementation of complete information labeling; However, because of the pre-opening treatment, it is not entirely within the scope of agricultural products. Prepackaged foods is managed by the State Administration of Market Supervision, while agricultural products are managed by the Ministry of Agriculture and Rural Affairs. However, due to the difficulty in defining its commodity attributes and supervision, the supervision of pre-opened coconuts is still in a gray area. It is precisely because there is no unified management that all kinds of packaging that consumers see in the market are determined by the merchants themselves, and there are indeed some security risks.

　　Li Shuguang called on operators to be self-disciplined and earnestly safeguard the health of consumers and the reputation of brands; Consumers should enhance their risk awareness and discrimination, and buy food in formal channels; Regulators should speed up the characterization of this kind of new formats and new foods, introduce corresponding regulatory measures as soon as possible, strengthen supervision and increase the cost of violation.

　　In addition, some people are worried about whether the pre-opened coconut will be added with additives. There is no ingredient list on the package, so consumers can’t check it.

　　Li Shuguang believes that if only a small mouth is opened on the coconut, it is difficult for merchants to add additives from it, so consumers don’t have to worry too much; If coconut water is poured out to make coconut milk, coconut jelly and other products, food additives may be added, but there are standards for the addition of additives. As long as the products meet national standards, consumers don’t have to worry about the health hazards caused by food additives.

Yichexun A few days ago, I obtained the mixed version of the declaration map from relevant channels. The logo of "hybrid" has been added to the rear of the new car, which is equipped with a 1.5T hybrid system with a declared value of 6.4L/100km.

The appearance of the hybrid version does not adopt a new generation of design, which is not much different from the current fuel version. Only the "hybrid" logo is added at the rear of the car.

The logo and the net on the front face are still chrome-plated, and the rear taillights are designed as through taillights, with dimensions of 4700mm long, 1860mm wide and 1746mm high respectively.

The hybrid version still uses 1.5T, and the hybrid system is composed of motors. Compared with the current fuel version of 1.5T, it will have stronger power and better performance. The official declaration is 6.4L, and the fuel version is reduced by 1L. Since the hybrid electric vehicle is not a new energy vehicle, the main competitor of the new car is the fuel version of the same price, and the advantage is naturally lower brought by the hybrid vehicle.

　　Source: IT house?

　　Today, Qin L DM-i, a brand-new mid-level car of BYD Dynasty, made its world debut in auto china in 2024. The car adopts a brand-new interior and exterior design language and is equipped with a fifth-generation DM-i hybrid system. The vehicle positioning is higher than that of Qin PLUS DM-i currently on sale, and the starting price may be more than 120,000 yuan.

　　According to IT House, the length, width and height of Qin L are 4830mm/1900mm/1495mm respectively, and the wheelbase is 2790mm, so Qin L is positioned as a mid-level car. In the car matrix of the current dynasty, the Qin family is a compact pin crown, the Han family is a medium and large pin crown, and the Qin L sword refers to the intermediate level, which just fills the gap between the two cars.

　　Qin L adopts "the aesthetics of the new country’s dragon face", "the front face of the dragon rhyme" is majestic, the side is slender and elegant, and the tail is designed with ultra-wide back shoulders, which makes the whole car show a "wide body and low body" posture, domineering and dynamic.

　　Qin l’s interior is inspired by Chinese painting, creating a "landscape painting cockpit" with high style. The integrated center console slowly unfolds around the rotating big screen, like a long scroll of the East floating on the instrument panel of the sapphire case, creating a strong sense of encirclement. Ergonomically comfortable seats and front McPherson rear multi-link independent suspension are adopted.

　　Prior to this, Qin L will have a major breakthrough in fuel consumption and endurance.
