Foreword

　　Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has attached great importance to seed industry, and repeatedly stressed the need to make up his mind to develop national seed industry and ensure national food security from the source. When the General Secretary of the Supreme Leader presided over the deliberation of the seed industry revitalization action plan in 2021, he emphasized that agricultural modernization is based on seeds, and the safety of seed sources should be raised to a strategic level related to national security. The 20th National Congress of the Communist Party of China put forward the important task of accelerating the construction of a strong agricultural country and consolidating the foundation of food security in all directions, and called for in-depth implementation of the seed industry revitalization action. At the Central Rural Work Conference in 2022, the General Secretary of the Supreme Leader emphasized that the seed industry revitalization action should be effectively achieved and the home-grown varieties should be firmly in their own hands. These important instructions and strategic arrangements have pointed out the way forward and provided fundamental follow-up for promoting the revitalization of seed industry in the new era and new journey.

　　In recent years, it is an important period for the rapid development of seed industry in China. The vitality of breeding innovation has been released and the pace of variety breeding has been obviously accelerated. In terms of the number of varieties, the number of approved varieties has increased greatly, providing more varieties for agricultural production; In terms of variety quality, high-quality green varieties are accelerated, which provides an important variety guarantee to meet the needs of people’s better life; In terms of variety types, special varieties have been approved one after another, which provides strong variety support for adapting to the transformation of agricultural production mode. At the same time, we should also see that with the rapid growth of the number of varieties, the problem of homogenization of varieties has become increasingly prominent, which is not conducive to the innovation and upgrading of varieties, but also brings difficulties to farmers’ scientific selection and use of seeds.

　　Ensuring the stable and safe supply of grain and important agricultural products has always been a top priority in building an agricultural power, and breeding and popularizing excellent varieties plays an important role in achieving this major strategic goal. In order to speed up the popularization and application of excellent varieties, improve the yield and quality level, and help guide farmers to select seeds scientifically and use seeds correctly, the Ministry of Agriculture and Rural Affairs has decided to compile and publish a national catalogue for the promotion of excellent varieties of crops from 2023, effectively guiding the industry to focus on demand breeding innovation and speeding up the upgrading of varieties.

I. General situation

　　In 2023, this catalogue will release 10 kinds of crops, including rice, wheat, corn, soybean, cotton, rape, peanut, potato, Chinese cabbage and cabbage, focusing on classification to guide the popularization and application of crop varieties. The released varieties include four types, including backbone type, growth type, emerging type and special type, forming a relatively complete variety promotion echelon to better serve the needs of agricultural seeds and farmers’ seed selection.

　　The backbone varieties have been approved (registered) for more than five years, the main grain, cotton and oil varieties have entered the top 10 in the suitable ecological area for three consecutive years, and the key vegetable varieties have entered the fifth place in the country for three consecutive years.

　　The growing variety has been approved (registered) for promotion for more than three years, and has outstanding performance in the national core exhibition base or provincial exhibition evaluation. The promotion area has increased rapidly, and it has entered the top 30 in the suitable ecological area (grain, cotton and oil) or the national (key vegetables), and is expected to grow into a backbone variety.

　　The budding variety is approved (registered) and popularized within three years, with good yield, resistance and quality, excellent comprehensive characters, excellent performance in the national core exhibition base or provincial exhibition evaluation, and great market potential. The formation enterprise or the integrated enterprise of breeding, breeding and promotion plans to promote it, and it is expected to further become a growing and backbone variety.

　　Specially-specialized varieties are newly approved (registered), meet the consumption needs of diversified markets, and can significantly improve the utilization rate of resources such as land, fertilizer, water, light and temperature, or have made breakthroughs and qualitative improvements in yield, resistance, quality, growth period, mechanization and new farming systems (such as ratooning rice and strip compound planting).

　　According to the above classification principle, based on the data of variety test, exhibition evaluation, statistics of main varieties’ extension area and production and operation of seed enterprises, recommended by provincial seed industry management departments and selected by experts, a total of 241 excellent varieties were introduced in 2023, including 36 rice, 29 wheat, 32 corn, 13 cotton, 22 soybeans, 26 rapeseed, 22 peanuts, 20 potatoes and 21 Chinese cabbage.

　　V. South China City Commercial Management

　　1, the introduction of special prevention and control guidelines, to adopt the "special rotation+party member Xianfeng Gang" model.

　　In order to help business owners in the park to improve their correct treatment of the epidemic, South China City Commercial Management issued the South China City Commercial Management Prevention novel coronavirus Epidemic Plan and the South China City Commercial Management novel coronavirus Epidemic Prevention and Control Operation Guide, so that every employee can understand the epidemic prevention and control and health knowledge, and carry out the epidemic prevention and control work correctly and effectively. In the publicity of prevention and control, the commercial management of South China City adopts the mode of "special person rotating guard+party member Xianfeng post", and the eight-city management project publicizes the knowledge of epidemic prevention and control around the clock.

　　2. Strengthen the control of the first line of defense for import and export. The professional market in the park covers a large area. In order to pay attention to the effectiveness of card point setting, each professional market only has one main entrance and exit, and the staff is on duty 24 hours a day to check the passing vehicles, so that every vehicle must be inspected and no one is missed. A strict registration and confirmation system is implemented for foreign personnel, so that the number of foreign personnel is clear and the detection effect is ensured.

　　3. Cooperate with the government, closely track and report in real time. The leaders of South China City Commercial Management cooperated with the port area industrial and commercial bureau, law enforcement bureau and other departments to investigate the relevant personnel discovered by the big data of the Ministry of Public Security, and carried out key epidemic prevention and disinfection on the surrounding areas and vehicles of the merchant. At the same time, the staff closely followed the development of the situation, cooperated with the port industrial and commercial bureau and professional medical staff to carry out medical examination on specific personnel, and reported the personnel’s condition to the government and the company in real time to ensure the first response, the first arrival and the first solution.

Have you ever paid attention to carcinogens around you? Recently, the topic of "super carcinogen Aspergillus flavus around us" has attracted attention in Weibo.

Aflatoxin is a strong carcinogen produced by Aspergillus flavus! As early as 1993, aflatoxin was classified as a class 1 carcinogen by the World Health Organization, with its toxicity 68 times that of arsenic, 10 times that of potassium cyanide, and 70 times that of dimethylnitrosamine, which is extremely destructive to liver tissue. Regular intake may increase the risk of liver cancer. [1]

In addition to aflatoxin, there are actually some "carcinogens" around us, which are likely to enter the diet and life every day.

1. Aflatoxin: moldy grain and nuts.

Among moldy foods, one kind of mildew comes from Aspergillus flavus, especially in grain. In 2007, an assessment of dietary exposure of Chinese aflatoxin published in China Journal of Food Hygiene pointed out that corn and rice were the main contribution foods to dietary exposure of Chinese aflatoxin. [2]

Reproduction and use of copyright pictures in the gallery may lead to copyright disputes.

In addition, peanuts and peanut oil may also contain aflatoxin.

Common sources of aflatoxin

Moldy corn, rice

Moldy, especially in foods with high starch content, such as corn and rice.

Deteriorated nut

When you eat bitter nuts, you must spit them out immediately and rinse your mouth.

Broken and unclean bamboo and wood chopsticks

Chopsticks themselves will not grow Aspergillus flavus, and starch is easily hidden in unwashed chopsticks, which poses a risk of mildew.

Inferior sesame paste

Using inferior and deteriorated sesame seeds and peanuts as raw materials, aflatoxin may exist in peanuts.

Earth-pressed peanut oil

Some "earth-squeezed oil" or self-squeezed oil has no quality control, and the equipment is not easy to be thoroughly cleaned, and the residual oil stains and grain residues are easy to mildew. [3]

2. benzopyrene: food that has been roasted and fried at high temperature.

Pan Zhanhe, deputy chief physician of the Oncology Department of Zhongshan Hospital affiliated to Xiamen University, said in the Health Times article in 2017 that heterocyclic amines and polycyclic aromatic hydrocarbons may be produced in the production process by barbecue or smoking, among which the most well-known one is benzopyrene, which may be contained in many baked and smoked foods. [4]

A study published in Jinan University in 2018 found that the intake of polycyclic aromatic hydrocarbons in the barbecue process was: eating barbecue food > skin contact > lung inhalation.

This means that during barbecue, the skin absorbs more carcinogens than the lungs inhale. [5]

Common sources of benzopyrene

roast

It may be produced during barbecue or smoking.

High temperature fried food

Cooking oil will produce a lot of benzopyrene at high temperature, and the higher the oil temperature, the more it will be produced.

Cooking oil fume

The cooking fume will also carry benzopyrene, so don’t wait for the oil in the pot to smoke before putting the food. [6]

3. nitrosamines: smoked and pickled food.

Zhang Qin, vice president of Jiangsu Cancer Hospital, said in the program "Meeting a Famous Doctor" on Jiangsu City Channel in 2019 that smoked bacon food contains a lot of nitrosamines, and the incidence of some digestive system tumors, such as esophageal cancer, is related to the intake of nitrosamines in the diet. When smoked food and wine are ingested together, the harm of nitrosamines to human health will multiply. [7]

Reproduction and use of copyright pictures in the gallery may lead to copyright disputes.

Pickled products often contain more nitrite. Although nitrite itself does not cause cancer, it will combine with protein to form nitrosamines when it enters the body. In addition, some nitrosamine compounds, such as nitrosodimethylamine, will be produced in the process of dehydration of Chinese salted fish, which are carcinogenic. [8]

Common sources of nitrosamines or nitrites

Processed meat products

Nitrite is added to some processed meat products such as sausages, ham and bacon.

Overnight dish

Overnight vegetables, especially overnight green leafy vegetables, will produce nitrite, and the nutrition will be discounted.

Smoked and cured food

Pickles, salted fish, bacon, high-salt pickled and smoked foods contain nitrite. For example, the most nitrite in pickles is between two or three days and ten days after the start of pickling. [9]

4. Tobacco tar: inhaled by tobacco burning.

Smoking and second-hand tobacco smoke are classified as Class 1 carcinogens. During the burning process of cigarettes, nearly 4000 new chemicals are formed. Most of these substances are harmful to people, among which nicotine, nitric oxide and tobacco tar are the most harmful, and the latter is the chief culprit of cancer. [10]

Moreover, smoking is not only a kind of cancer that causes lung cancer, but also closely related to the occurrence of nasopharyngeal carcinoma, oral cancer, esophageal cancer and other related cancers.

5. Acetaldehyde: an intermediate product produced after drinking.

The main component of wine is ethanol, which is oxidized into acetaldehyde after entering liver cells. The latter is hepatotoxic and carcinogenic, and excessive accumulation in the body will cause serious harm to the liver. [11]

Reproduction and use of copyright pictures in the gallery may lead to copyright disputes.

Acetaldehyde related to the intake of alcoholic beverages is classified as a class 1 carcinogen. According to the statistics in the 2014 World Cancer Report, 3.5% of cancers are caused by alcohol, and one in every 30 cancer deaths is caused by alcohol. [12]

Although there are various carcinogens around us, carcinogens can cause some cancers, which refers to a possibility after long-term and excessive intake. If you only eat a little occasionally or touch it occasionally, don’t worry, it’s still safe.

　　[New Car Launch in car home] On the evening of November 12th, Ferrari officially announced on its website that its (|) convertible model, the Ferrari SF90 Spider, made its world debut. The new car will be equipped with a convertible mechanism that can be opened and closed electrically, which is the first convertible hybrid model produced indefinitely after Ferrari LaFerrari Aperta. It is reported that the new car will be delivered before the end of spring or early summer in 2021.

"Screenshot of the global online conference, please forgive the poor quality"

More exciting videos are all on the car home video platform.

● New car features
Ferrari’s first plug-in hybrid production convertible model

　　In terms of appearance, the new car is basically the same as the hard-top version of SF90 Stradale, with an active aerodynamic kit integrated on the front enclosure, and the "Tomahawk"-shaped front nose cone is reminiscent of F1 racing cars. The headlight groups on both sides of the new car adopt the shape of the letter "L" and merge with the air inlet below, which also forms an air bridge design on the front engine compartment cover to increase the downforce of the front of the new car.

　　On the side of the car body, the new car adopts a very streamlined shape, and the design of different colors on the roof and body highlights the unique body lines of its sports car. The new car adopts a folding hardtop convertible mechanism, which can be opened and closed in only 14 seconds, and the convertible only takes up 100 liters of trunk space when it is put away. Starting from the B-pillar of the car body, the whole rear cover has become a mechanism that can be opened upwards, so as to retract the roof into the "trunk". In addition, the opening mechanism does not affect the overall line of the side air intake and roof of the new car, and it still looks smooth. The wide side fenders at the front and rear of the new car, with 20-inch spokes and ceramic carbon fiber braking system, make the new car look full of gas.

　　In the rear part, the new car uses a duck-tail spoiler with a large size. Although it is a hard-top convertible design, the rear cabin cover is still made of glass. After the convertible is put away, you can still see the powerful V8 engine, and you can enjoy the roar brought by the V8 engine and the quiet under pure electric cruise. Both of them are very comfortable. The exhaust system with the center and double outlets has also been specially adjusted by Ferrari, which can make a more pleasant sound. In terms of body size, the length, width and height of the new car are 4704/1973/1191mm and the wheelbase is 2649mm respectively.

　　In the interior part, the new car still adopts the center console design that surrounds the driver’s seat, and its surface is covered with a large number of carbon fiber component decorative panels. Of course, the corresponding materials can also be customized according to the needs of users. The new car adopts an all-LCD dashboard, which integrates a newly designed HMI human-computer interaction interface, and the vehicle information with digital display style is clear at a glance. With the touch-type multifunctional flat-bottomed sports steering wheel, the driver can complete various multimedia operations and vehicle regulation without leaving the steering wheel. In addition, the new car also introduces a head-up display system, which can project the main information on the windshield in the driver’s field of vision, so that the driver can concentrate on driving.

　　In terms of power, the new car is still equipped with a plug-in hybrid power system consisting of a 3.9T twin-turbocharged V8 engine and three motors. The comprehensive power of the system is 1,000 horsepower, and the pure electric battery life can reach 25 kilometers. In terms of transmission system, the new car is matched with an 8-speed dual-clutch gearbox and equipped with a full-time four-wheel drive system (RAC-e). The acceleration time of 0-100km/h is 2.5 seconds, and the acceleration time of 0-200km/h is only 7 seconds. In addition, the car will provide four power modes for the driver to choose from. It is worth mentioning that the new car will provide the owner with regular maintenance service for up to seven years. The seven-year original factory maintenance plan is also for all Ferrari models, and covers regular routine maintenance for the first seven years.

● New car background

　　Ferrari SF90 Stradale was launched in the world on May 30, 2019, and was launched and listed in China on October 29 of the same year. The price of the new car was 3.988 million yuan. The launch of SF90 Stradale was to pay tribute to the 90th anniversary of the founding of Ferrari, and it was also a brand-new positioning car launched by Ferrari for many years. Different from the traditional convertible sports car, V8 sports car, V12 sports car, GT sports car and flagship sports car, the new car is a work of art that Ferrari engineers combine track genes accumulated for many years with new plug-in hybrid technology, and it is also an important product launched by Ferrari for electrification transformation.

● Edit Comment:

　　In fact, it seems that the global epidemic has not affected the sales of these ultra-luxury models too much, and the rich will still be obsessed with customizing all kinds of super sports cars. The Ferrari SF90 model is not only the representative of Ferrari technology, but also a rare hybrid version of Ferrari production models. After enjoying the stimulation brought by the twin-turbo V8 engine, it can also contribute to the global environmental protection cause. After all, the new car is different from LaFerrari Aperta, and the SF90 can drive in a purely electric way.

　　According to Ferrari’s electrification process, although Ferrari said that it would not let its models completely enter the era of pure electrification in the short term, it is undeniable that the power increase brought by electrification cannot be ignored. SF90 is such a model that integrates Ferrari’s cutting-edge electrification technology, which not only brings powerful power performance, but also leads Ferrari into a new energy era.

Another institutional innovation of patent transformation and application has been comprehensively promoted!

On June 1, 2021, the newly revised patent law was implemented, and the patent open licensing system was added. This system is conducive to the realization of "one-to-many" patent licensing, reducing institutional transaction costs, improving the efficiency of patent transformation, and opening up the "last mile" of the transformation of scientific and technological achievements into new quality productivity. With the newly revised Detailed Rules for the Implementation of the Patent Law of People’s Republic of China (PRC) officially implemented on January 20th, 2024, the patent open licensing system has been fully implemented. The patentee voluntarily submits a patent opening license statement, and the patent license fee is clearly marked, which is "widely announced" to the whole society by the patent administrative department of the State Council. Any unit or individual can obtain an implementation license by notifying the patentee in writing and paying according to the marked price, and all licensees are treated equally.

Recently, China National Intellectual Property Administration issued a notice on comprehensively promoting the implementation of the patent open licensing system (hereinafter referred to as the notice) and the Measures for the Mediation of Disputes in the Implementation of Patent Open Licensing (for Trial Implementation) (hereinafter referred to as the "Working Measures") and other documents to standardize related work and further promote the implementation of the patent open licensing system.

Open license to build a patent docking bridge

"In just half a year, this patent has created an economic value of nearly 10 million yuan for us!" Hu Chenguang, general manager of Mingji Erffa Intelligent Industrial Technology (Dalian) Co., Ltd. told the reporter. This small and medium-sized enterprise located in Dalian, Liaoning Province, is committed to developing industrial robot automation technology and equipment. At the end of last year, Hu Chenguang found in the local trading center that Dalian University’s open license patent "an improved Smith predictive control method based on CRNs" met the technical requirements of enterprises, and thus cooperated with the research team of associate professor Lu Hui of Dalian University in the automatic control of biochemical systems. This patent was applied to the company’s industrial robots and automatic cleaning equipment, which greatly improved the system performance of the equipment.

"I didn’t expect to reach a cooperation so smoothly this time. We are very eager to achieve technological breakthroughs in our products. In the past, companies looking for patents faced the problems of dislocation of demand and research and unequal information, so it was difficult to find patent acquisition channels. In the patent open licensing work, publicly displaying the patents with conversion intention in colleges and universities allows us to find more good patents. " Hu Chenguang said.

This is a vivid practice for Dalian University to gain market value through patent opening license.

As early as May, 2022, China National Intellectual Property Administration launched the pilot project of patent conversion and open license. By the end of 2023, more than 3,200 patentees in 22 pilot provinces of patent opening license had participated in the pilot project, and more than 59,000 patents were matched and pushed to more than 110,000 small and medium-sized enterprises, and more than 17,000 patents were granted. Since January 20th this year, the patent opening license statement put forward by the patentee has been announced to the public through the patent bulletin after passing the examination in China National Intellectual Property Administration.

At present, 90 patents of Dalian University have been approved for announcement. "In 2022, when China launched the pilot project of patent opening license, the school actively explored this innovative measure. The patent open license allows the school to further establish a cooperative relationship with enterprises in Industry-University-Research, which more effectively promotes the wide application of technology. " Chen Huiyuan, a researcher at the Science and Technology Department of Dalian University, said that at present, more than 20 enterprises have applied to renew their contracts and explore further cooperation after transforming and applying the school open license patents.

In the statement of patent opening license issued by China National Intellectual Property Administration, many enterprises are actively carrying out patent opening license besides universities and scientific research institutions. Jingxin Communication Technology (Guangzhou) Co., Ltd. (hereinafter referred to as Jingxin Communication) is one of them.

"The company proposed a key technical solution for high-performance low-carbon life antenna, which realized the double improvement of network performance and green energy saving, and laid a technical foundation for the realization of full-band high-performance low-carbon life antenna. In order to make green antenna technology more widely and deeply applied and promoted in the industry, we screened two core technology patents for open licensing, and combined with patent technology, market, law and other factors, conducted multi-dimensional patent valuation and determined the patent open licensing fee. " Li Xuefeng, senior vice president of Jingxin Communication, told the reporter.

At present, these two patents have successfully obtained a total of 2.5 million yuan in license fees. Li Xuefeng said that the rapid application of the open license patent not only showed the core competitiveness of the company’s independent intellectual property rights, but also helped to enhance its popularity and brand value, further promoting the prosperity and win-win situation of the industry ecology.

Supporting measures to promote the efficient operation of the system

The notice issued this time and the "Working Measures" have standardized a number of tasks in the implementation of the patent open licensing system.

According to the notice, the patent open license statement will be announced to the public through the patent bulletin after passing the examination by China National Intellectual Property Administration, and the public can inquire about the announcement information such as the patent open license statement and the registration of the license through the China Patent Publication Announcement System (http://epub.cnipa.gov.cn/). Patent open license announcement data is fully open to the public through the public service system of intellectual property data resources, which is convenient for all parties to inquire, retrieve and obtain. For the patent opening license reached, the intellectual property offices of all provinces (municipalities directly under the Central Government and autonomous regions) shall supervise and guide the patentee or licensee to file with China National Intellectual Property Administration in a timely manner in accordance with relevant regulations.

With regard to the estimation of licensing fees for patent opening, which is of concern to the industry, the notice is clear. According to the provisions of the Patent Examination Guide, the licensing fees paid at a fixed fee standard are generally not higher than 20 million yuan; Paid by royalty, generally not higher than 20% of net sales or 40% of profit. If the license fee is higher than the above standard, the patentee shall be guided to license by means of ordinary license.

At the same time, the notice requires that the intellectual property offices of all provinces (municipalities directly under the Central Government and autonomous regions) should strengthen the interpretation of the national standards of the Guidelines for Patent Evaluation and the Guidelines for Estimating the Use of Open Licenses (for Trial Implementation), and guide the patentees to uphold the concept of fairness, rationality, mutual benefit and practicality, accurately grasp the "one-to-many" characteristics of open licenses and the characteristics of small amount, inclusiveness and convenience, and reasonably estimate the license fees.

Focusing on possible intellectual property disputes, the Working Measures clarify the acceptance conditions of the application for mediation of disputes in the implementation of patent open license, the documents and materials that the parties should submit, the conditions for making an acceptance decision, the circumstances of non-acceptance and the acceptance registration, etc., so as to timely resolve the disputes arising in the implementation of patent open license.

"The patent open license system aims to promote the patent transformation and application. Its core system function is to solve the problem of asymmetric supply and demand of patent license, which can effectively promote the disclosure of transaction information and reduce the transaction cost of patent license, thus promoting the patent transformation and implementation." Ma Yide, dean and professor of the School of Intellectual Property, University of Chinese Academy of Sciences, suggested that for the innovation subject, whether the patent license is achieved depends on the docking of market supply and demand. We should fully consider the patent quality and market demand, and open the license for high-value patents that meet the market demand. For the enterprises that accept the open license, after the open license is reached, they should actively file with China National Intellectual Property Administration to maintain the priority effect of obtaining the license, so as to avoid the right holder’s punishment of the patent during the open license period, which will affect the interests of the implementers. At the same time, the declaration of open license can also enable the public to make reasonable investment planning by understanding the implementation of the open license of a specific patent, so as to avoid disorderly competition or excessive investment caused by the large number of licensees of the same patent.(Author CoCo WU)

Seal and Seal 06 are both medium-sized cars of BYD brand, and they are different in price, configuration and market performance. The following are their main differences:

1. Price: The guide price of Seal is 149,800-249,800 yuan, while the guide price of Seal 06 is 99,800-139,800 yuan. The former is positioned as a mid-to high-end model, while the latter is positioned as a low-end model.

2. Interior: Seals’ seats are made of leather and equipped with panoramic skylights. The first row of seats has heating and ventilation functions. The seat material of Seal 06 is leather, and it is also equipped with panoramic sunroof, but the function of the first row of seats has not been announced. Therefore, the seal’s interior is of higher quality and better comfort.

3. Market performance: The national sales volume of seals in June was 8,138, ranking 65th, with an average daily attention of 55,979. The national sales volume of seals in June was 7625, ranking 69th, with an average daily attention of 122083. It can be seen that the market performance of Seal 06 is better, which may attract more consumers because of its lower price.

4. Space: The body size of the seal is 4980*1890*1495, the wheelbase is 2900, and the number of seats is 5. Seal 06 has a body size of 4830*1875*1495, a wheelbase of 2790 and five seats. Seal is slightly larger than Seal 06 in body size and wheelbase, thus providing more interior space.

5. Power: Seals and Seals 06 both use electronic continuously variable (E-CVT) gearboxes with a maximum speed of 180 km/h.. Seal is equipped with a 1.5T 139 L4 engine, while Seal 06 is equipped with a 1.5L 101 L4 engine. The former is more powerful, but the fuel consumption may be relatively high.

In a word, Seal and Seal 06 are different in price, interior, market performance, space and power. Seals are positioned in the middle and high end, with more luxurious interiors, more space and stronger power; Seal 06, on the other hand, is positioned in the middle and low end, and its market performance is good, but it is slightly inferior to seal in interior and power. Consumers can choose the right model according to their own needs and budget.

　　Wenzhou Net News The ongoing two national conferences have brought public data security into the public eye. Hu Chengzhong, deputy to the National People’s Congress and chairman of the board of directors of Delixi Group, suggested that with the epidemic prevention and control entering a new stage of "Class B and B management", the "health code" has been completely stopped, and the relevant data collected by the "health code" should be deleted within a limited time to reassure the people.

　　In Wenzhou, everyone is most familiar with the "Wenzhou Epidemic Prevention Code". It is equivalent to the merger of "health code" and travel card, and was officially launched on November 1, 2021. Relevant reports show that the number of users of Wenzhou Epidemic Prevention Code reached 8.96 million only two months after it was launched, and by April 2022, the number of users reached 14.39 million, and the number of bright codes per day reached more than 18 million.

　　In the prevention and control of epidemic situation, "health code" played a great role and became a highlight of China’s anti-epidemic experience. At present, where should the massive data behind the "health code" go?

　　Completely delete the square

　　Wang Xianming, deputy dean and professor of the School of Data Science and Artificial Intelligence of Wenzhou Institute of Technology, clearly understands his point of view: absolutely support, and the "health code" data should be completely deleted.

　　He believes that on the one hand, from the perspective of the necessity of data retention, epidemic prevention and control has entered the "Class B B Management", and there is no reason to use these data again, so there is no need to keep them. On the other hand, data storage is bound to have security risks, although it depends on where the data exists. Is the platform reliable? But this only shows that the security risk of data leakage is big or small, and it can’t completely avoid the risk.

　　"The importance of personal data is self-evident, so when deleting it, we should pay more attention to the security of the data during the destruction process, and ensure that the data is completely destroyed." Wang Xianming said.

　　Also supporting the positive view is a professional who has been fighting in the front line of epidemic prevention for three years. He believes that for the traceability work, collecting personal data in epidemic prevention and control is to quickly trace the trajectory of infected people in the past 7 days and 14 days in the event of an epidemic. This supports the epidemiological investigation to the maximum extent. Through the data, we can basically judge where the infected people are infected, and provide reference for the subsequent delineation of medium and high-risk areas. However, the professional also pointed out that after the epidemic entered a new stage, it is no longer necessary to trace the source as before, so it is no longer necessary to rely on these historical data at present. "After all, this is the transfer of personal privacy made by the public in order to cooperate with the overall situation of epidemic prevention."

　　What do ordinary citizens think? Let’s see what the supporters in the positive camp say — —

　　Citizen Li Tao: No suggestion, delete it immediately. The mission of "health code" has been completed, and relevant data should be completely deleted.

　　Citizen Qiao Qiao: I am a 2018 undergraduate student. I was often locked in school from my sophomore year until graduation. During the period of school closure, every day, in addition to doing nucleic acid, the "health code" was checked. Now when I see the "health code", I will think of that painful memory, especially hoping to completely delete the "health code" and related data.

　　Natural extinction of the opposing side

　　A data engineer, who asked not to be named, believes that the key issue is not whether the data should be saved, but what can be done to make the data more secure.

　　In this regard, Xu Gang, Dean of the School of Artificial Intelligence of Zhejiang Security Vocational and Technical College, also said that it is not easy to generate massive data on specific topics, and it is of high value in professional fields. Massive data should be preserved for a long time, and it will be better through natural extinction. He explained that theoretically, every kind of data has a life cycle, which is divided into collection — Handling — Transmission — Exchange — Six stages of destruction. In the short term, it is necessary to consider that the destruction needs to be based on certain policies, regulations and technical means, and not only will there be risks that cannot be traced back, but also corresponding costs and expenses will be incurred. However, natural extinction, such as expired batch destruction, storage equipment scrapping, natural disaster destruction and other factors, is conducive to the long-term reuse of data, especially the epidemic data can be used for long-term research on citizens’ health, epidemic spread theory, optimization methods of epidemic prevention measures, non-compliance behavior during the epidemic, etc. Of course, it is necessary to strictly ensure data security in this process.

　　There are also many citizens’ voices in the anti-party camp — —

　　Netizen "Wendy": As long as it is not leaked, the data can be kept reasonably, and it doesn’t matter if it is not deleted. In case of special circumstances in the future, these data can be used as historical situations for analysis, which may play an emergency role.

　　Citizen Chen Xi: I remember that many people were sending friends to commemorate the trip card when it was off the line. Although there were countless "health code" checks and negative nucleic acid certificates during the epidemic, there were still many warm moments during the epidemic. I hope to keep the "health code" and the data inside, which can be regarded as a commemoration of this special period.

　　What do you think of whether the data of "health code" should be deleted?

　　The proposal of Wenzhou delegates to the NPC and CPPCC triggered a debate?

　　Do you want to delete the "health code" data?

　　Pro: completely delete VS anti: natural extinction

() The operating comments of the Board of Directors in 2023 are as follows:

　　I. The industry in which the company is located during the reporting period.

　　During the reporting period, the company mainly engaged in LED, semiconductor memory new generation information technology business, comprehensive energy service business and advertising media business, providing customers with customized and integrated solutions.

　　(a) the new generation of information technology business in the industry

　　1. LED industry

　　China has written its strong support for the development of the third-generation semiconductor industry into the Tenth Five-Year Plan. LED is an important industry field of the third-generation semiconductor and has been widely used in many application scenarios such as lighting, backlight and display. 2023 is a year in which challenges and opportunities coexist: the downward pressure on the global economy has not diminished, the impact of global public health events has weakened, the macro economy has gradually recovered, and the overall market is still full of vitality; New challenges, new opportunities, new technologies and new applications coexist, and the LED industry as a whole is under pressure to repair. During the reporting period, the concentration of packaging links continued to increase and the competition became increasingly fierce; The overall revenue of the packaging industry is under pressure, and the sub-sectors such as automotive electronics and MiniLED are growing rapidly; The demand recovery of overseas lighting market has accelerated and exports have accelerated; Domestic market segments such as municipal lighting, commercial lighting and educational lighting are picking up, driving the LED industry forward.

　　2. Semiconductor memory industry

　　The semiconductor memory industry naturally has a strong periodic property. Since the second half of 2022, the unbalanced state of oversupply in the storage market caused by sluggish terminal demand and high inventory of enterprises has led to the decline of NANDFlash and DRAM prices for four consecutive quarters from Q3 2022 to Q2 2023. During this period, the original storage factories started to reduce production and continued to reduce production, drastically reducing supply, trying to slow down the downward trend of prices and reduce inventory pressure; However, the production reduction effect has a time limit, and the continuous decline of this price has caused huge performance losses to the original storage factory, and the continuous decline will even affect the medium and long-term technology investment and capacity planning. As a result, under the change of strategy of giving up the market share and turning to restoring profitability as the primary goal, the original storage factory began to strongly increase the storage price from the third quarter of 2023. The storage market became a de facto low point in the second quarter of 2023. In the third quarter, the prices of some products diverged, and in the fourth quarter, the storage prices rose in an all-round way. In the second half of 2023, the storage price rebounded, breaking the downward trend since the third quarter of 2022, and the price returned to the upward track.

　　According to the data of CFM flash memory market, the global storage market scale decreased by 20%, increased by 9% and increased by 16% in the first quarter, the second quarter and the third quarter of 2023, respectively. It is expected to maintain the double-digit growth rate in the fourth quarter and resume the year-on-year growth, but the storage market scale in 2023 will still decrease by 38% to 86.8 billion US dollars year-on-year. In 2023, eSSD, with enterprise/server as the main application field, consumed about 29% of the global NANDFlash production capacity, Mobile products with smart phone applications as the main consumption capacity, and cSSD with PC applications as the main consumption capacity.

　　Affected by the continuous production reduction of the original factory, the rising wafer price, the month-on-month warming of the three major storage application markets of PC, mobile phone and server in the second half of 2023, and the acceleration of artificial intelligence, the income change of storage application manufacturers showed a trend of first restraining and then rising, and it became a low performance in the first quarter of 2023. Stimulated by the rebound of storage prices in the third quarter, the market demand for stocking increased rapidly, which led to the gradual increase of storage application manufacturers’ income and the rebound of operating profit margin.

　　(2) Comprehensive energy industry

　　In essence, comprehensive energy service is to change the previous mode of separate planning, design and operation of electricity, gas, cold and heat, and coordinate and optimize the distribution, conversion, storage and consumption of all kinds of energy in operation by means of information technology, intelligent technology and management improvement. Its core value lies in improving energy utilization efficiency and realizing energy conservation and emission reduction.

　　Energy conservation and emission reduction is an inevitable requirement to achieve the policy goal of "carbon neutrality". Under the background of "carbon neutrality" policy, the country has successively introduced the policy of "double control of energy consumption" in terms of total energy consumption and intensity, and gradually turned to the policy of "double control of carbon emission", further highlighting the value of energy-saving services. The development of energy-saving service industry promotes the demand for comprehensive energy services.

　　(3) Advertising media industry

　　In 2023, with the outbreak of AI big model, the rise of small program games and micro-short plays, China’s Internet advertising industry has significantly demonstrated the characteristics of diversification, innovation and intelligence. According to China Internet Advertising Data Report 2023, the scale of Internet advertising market in China is estimated to be 573.2 billion yuan in 2023, an increase of 12.66% compared with 2022, and the growth rate tends to be flat and the competition is intensified. With the further increase in the proportion of Internet advertisements, short video advertisements and effect advertisements, TV advertisements, long video advertisements and brand advertisements are on the decline, and TV advertisements and long video advertisement service providers are facing the challenges of shrinking market demand, fierce competition and transformation and upgrading.

　　(4) Possible risks and countermeasures

　　1. Supply chain risk and market competition risk brought about by changes in global macroeconomic and social situation.

　　With the global economic and trade frictions, geopolitical conflicts and other uncertainties and uncertainties in the global macroeconomic and social situation, the normal circulation of the supply chain of the semiconductor electronic industry chain faces certain risks, which may lead to unstable supply of raw materials and large price fluctuations, thus adversely affecting the development of China’s semiconductor industry. If the macroeconomic and social development is less than expected, it will further intensify the market competition in the LED industry, semiconductor memory industry and advertising media industry where the company is located, which may lead to a decline in gross profit margin.

　　The company will closely follow the changes in the supply chain of the global semiconductor electronics industry chain and take appropriate measures in a timely manner to reduce the risks in the supply chain of the industry chain; Focus on high-end differentiated segments, increase product research and development, improve the level of automation and intelligence, and enhance profitability; Strengthen brand and market channel construction and broaden business sources.

　　2. Risk of accounts receivable recovery

　　The customers of the company’s LED lighting projects are mainly government units and institutions. Due to the macroeconomic environment, there is a risk that some "old-fashioned" customers’ accounts receivable cannot be recovered, which is not conducive to the promotion of old projects and the undertaking of new projects, thus affecting their performance. The advertising media business is affected by industry policies and development, customer operating conditions, etc., and there may be risks that individual accounts receivable cannot be recovered on schedule, which will adversely affect performance.

　　The company will strengthen the collection of creditor’s rights, and control the risk of accounts receivable recovery by strengthening the collection, doing a good job in accounts receivable management and strengthening incentives and constraints.

　　3. The development of semiconductor memory business is less than expected.

　　The company has entered the field of storage semiconductors for a short time, and is still in the initial stage of capacity building of products, supply chains, channels and brands. In the course of operation, it may face a series of risks, such as industry development falling short of expectations, unstable supply of main raw materials and price fluctuations, supply chain development and integration, iteration of technological innovation and product upgrading, and brain drain. The company will give full play to the advantages of Hubei State-owned listed company with mixed ownership, located in Guangdong-Hong Kong-Macao Greater Bay Area, tilt its capital, policies, talents and other resources to Wanrun Semiconductor, and support it to effectively expand and strengthen its semiconductor memory business, making it a new generation of information technology main industry of the company.

　　4. Risk of exchange rate fluctuation

　　The company’s lighting business mainly focuses on overseas exports. At present, the RMB exchange rate is subject to a floating exchange rate system, and the company’s international business is settled in foreign currency. The price change of RMB to US dollars and other currencies may bring uncertain influence to the company’s product price competitiveness and income.

　　The company will pay close attention to the exchange rate changes, and reduce the adverse impact of exchange rate fluctuations on the company’s performance by improving product technology innovation and service level and reasonably controlling foreign exchange risk exposure.

　　5. Risk of policy change

　　New energy and comprehensive energy businesses such as wind power and photovoltaic are greatly influenced by industry policies, and the risk that the operating performance of this part of the company fluctuates greatly due to the adjustment and change of industry policies is not ruled out. The company will pay close attention to policy trends, adjust business strategies in a timely manner, cultivate business sectors with policy-oriented layout, and actively participate in the policy formulation process to strive for a favorable industry development environment.

　　6. Risk of impairment of goodwill

　　If the macro-economy and the development of the industry in which the company acquired the enterprise are still less than expected, the operating performance of the company acquired the enterprise may also be less than expected, which will lead to the risk of goodwill impairment and adversely affect the overall operating performance of the company.

　　The company will strengthen its operation and management, empower the development of acquired enterprises, and promote the expansion of its business scale and the improvement of its profitability through measures such as resource coordination, risk control and financial support.

　　Investors are requested to invest rationally and pay attention to risks.

　　It has been half a month since the normalization of nucleic acid screening in various places. As the weather turns hot, the work of nucleic acid sampling and sample transportation becomes more difficult. Experts said that although the working environment is even worse, especially for some outdoor sampling points, the sample collection, storage and transshipment work should still be carried out in accordance with the specifications and should not be slack.

　　Battery car transfer sample

　　June 15th is the first hot day since Shanghai entered Mei, with the temperature climbing to 36 degrees and the outdoor ground temperature even higher. The first financial reporter saw in an open-air nucleic acid detection point in Shanghai that the temporary tent could not stop the scorching sun, and the sampling personnel wore protective clothing, and their faces were sweating, while there were no electric fans or cooled ice cubes outdoors. Also exposed to the scorching sun are tubes of nucleic acid reagent samples being collected.

　　The sampling time at this sampling point is from 1: 00 to 4: 00 in the afternoon. After the sampling stopped at 4: 00, the staff put the last batch of samples into a suitcase-sized small refrigerator, which was close to 4: 30. A courier arrived at the testing point by car battery car, ready to take them away.

　　I saw that the picker opened the refrigerator and hastily stuffed nearly 20 tubes of nucleic acid reagents in sealed bags into black shoulder bags, while the battery car was filled with yellow medical waste bags collected from multiple inspection points.

　　Now he will carry the samples and medical wastes to a nearby "transfer station", and then these uniformly collected samples will be transferred to the designated testing laboratory by special vehicles. He claimed that this was the sixth time he had transshipped samples today, three times in the morning and three times in the afternoon, thus ending the six-hour working day agreed in the contract.

　　According to the transshipman, the point where he collects samples every day is not completely fixed, and sometimes an extra sampling point is added temporarily, which leads to the delay of his arrival at the next point, so the actual working time is more than 6 hours.

　　A sampler of normalized nucleic acid kiosks told the First Financial Reporter that in principle, a batch of samples will be transported away every hour, but in practice, the time is not so fixed, mainly depending on whether there are enough people to transport them. Their main tool is a battery car, which transports the reagents collected from several nearby testing points to the assembly point and then sends them to the testing laboratory by special car.

　　However, for the above process, an infectious disease expert with rich field sampling experience said that this sample processing method is worrying, and the sample storage and transshipment are very inconsistent with the basic norms.

　　"We who do infectious diseases know that the most important thing is that all operations must be carried out in strict accordance with norms and standards. The storage temperature and transfer time of nucleic acid samples have strict standardized processes, which is definitely not convenient." The above experts told the First Financial Reporter.

　　The guide has clearly stipulated.

　　The Implementation Guide for COVID-19 Nucleic Acid Testing Organization (Second Edition) clearly stipulates the preservation and transportation of samples, which should be kept at low temperature (2-8 degrees Celsius). In principle, samples should be collected every 2 hours for transportation, and the samples should be delivered to the laboratory 4 hours after collection.

　　On the basis of the above guidelines, Shanghai has further put forward "126" requirements for nucleic acid testing institutions, that is, collecting and transporting a batch of samples every hour, transporting the samples to the testing institutions in 2 hours by vehicles, and completing the testing in the laboratory within 6 hours. In terms of sample transfer, the time requirement is reduced by half compared with the guideline, but in fact, it is very difficult to achieve such a goal. If the sample is not transferred in time, it will not only affect the quality of the sample, but also affect the waiting time for detection.

　　In this regard, the above-mentioned infectious disease experts told the First Financial Reporter: "Since there are norms, it should be strictly implemented in accordance with the norms. For example, it is stipulated that samples should be shipped every hour or two, and someone should come to pick them up when they arrive, instead of seeing that there are enough people to pick them up. If not, just wait."

　　The expert also warned that as the weather gets hotter, if the nucleic acid reagent cannot be stored at low temperature in time during transportation, or exposed to the sun for a long time, it will increase the risk of inaccurate nucleic acid test results.

　　He told the First Financial Reporter: "You should know that ribonuclease is ubiquitous. It exists in the air and anywhere. When you open the lid of the nucleic acid test tube, it may enter the test tube. At the temperature above 37 degrees, Rnase will easily degrade RNA, and the whole process only takes 10-15 minutes. If there is a very low virus load in the test tube, it will be diluted after ten mixes.

　　According to the observation of the first financial reporter at some nucleic acid detection points, in some mixed-tube tests, the actions that do not meet the operating standards include picking a person without screwing on the cover, which also increases the risk of exposing the sample to the air.

　　The above experts added that although adding some components, such as diethyl pyrocarbonate (DEPC), to the reagent can help to inhibit Rnase, these components will increase the cost of the reagent, and standard nucleic acid reagents are generally not added. "The easiest way is to keep it at low temperature and transport it in time. Even using ice cubes to cool down is helpful. Ice cubes have no cost and can be reused." He told the first financial reporter.

　　He also stressed that the basic operation in transferring samples is to put the samples into two-layer sealed packages and avoid the test tubes from tipping, so as to prevent the reagent from leaking and polluting other samples because the cover is not tightened.

　　Professor Lu Hongzhou, president of Shenzhen Third People’s Hospital, told the First Financial Reporter: "The best way to solve this problem is to collect samples regularly."

　　Professor Shen Hanming, an expert in cell biology at the University of Macau, told CBN: "In theory, there is a protective solution in nucleic acid reagents, and some components can inhibit RNA degradation to a certain extent, but even so, in principle, reagents should not be stored at room temperature and high temperature for a long time."

　　Changsha Evening News (all-media reporter Peng Fang correspondent Chloe Wang Zeng Fan) Ms. Li, 50, has the greatest pleasure of cooking a sumptuous dinner for her family after work every day. A few days ago, Ms. Li participated in the physical examination of the unit. The results of low-dose spiral CT showed that "the space-occupying lesion of the upper lobe of the right lung does not rule out malignant lesions", and she was subsequently diagnosed as peripheral lung cancer in Hunan Cancer Hospital. Ms. Li wondered how she and her family could get lung cancer because they don’t smoke, and they usually have a healthy diet and a regular schedule. Wang Wenxiang, director and chief physician of the Second Department of Thoracic Surgery, Hunan Cancer Hospital, pointed out that in recent years, more and more patients with peripheral lung cancer were found in physical examination, and most of them were female patients who did not smoke. The academic circles thought it was related to their long-term exposure to high-temperature kitchen fumes.

　　Some surveys have found that women’s long-term exposure to high-temperature fumes will increase their risk of lung cancer by 2-3 times. Among non-smoking female lung cancer patients, more than 60% have long-term exposure to kitchen fumes; 32% women like to fry food in high-temperature oil when cooking, and the kitchen doors and windows are closed or poorly ventilated.

　　Wang Wenxiang pointed out that different cooking oils have different smoke points, and the higher the smoke point, the healthier the cooking oil. Among the commonly used edible oils, camellia seed oil has a high smoke point and can be used as a healthy first choice for cooking. In the cooking process, try to use medium fire, and control the temperature when cooking, so as not to smoke as the limit, which can not only reduce the damage of fatty acids and vitamins caused by high temperature, but also minimize the generation of smoke; Try to choose a pot with a thick bottom for cooking, so as to reduce a lot of oil smoke generated by the sharp rise of temperature in the wok; Try to use cooking methods such as steaming, boiling and stewing to reduce the oil smoke caused by frying; Ensure good ventilation in the kitchen, clean the range hood regularly, and wear a mask when necessary to reduce the smoke inhalation.

　　Wang Wenxiang reminded that the clinical cure rate of early lung cancer is over 80%, especially for women’s early lung cancer, most of which are peripheral lung cancer. Thoracoscopic surgery can achieve radical cure of lung cancer through 1 ~ 3 keyhole-sized operation incisions, and the curative effect is not inferior to that of large incision open surgery.
