　　Lowering blood pressure, lowering blood lipid and controlling diabetes are good for stomach, kidney and liver, and even cure all diseases … … False propaganda and fraud of health food are widespread, and consumers are unbearable. Are the various health care functions promoted by businesses true and effective, and how many scientific evidences are there? Many consumers will be skeptical or fall into a trap. A few days ago, the long-awaited "Management Measures for Raw Materials Catalogue and Health Function Catalogue of Health Foods" was released, which provided institutional guarantee for "managing, managing and optimizing" health foods, making health foods more scientific, effective, safe and healthy, and allowing consumers to better understand the efficacy of health foods.

　　In recent years, China’s health food industry has developed rapidly with an output value exceeding 300 billion yuan. With the rapid development of the industry, the problems of health food fraud and false propaganda have gradually emerged. Since 2017, the State Council Food Safety Office has jointly carried out special rectification of food health food fraud and false propaganda, and investigated and dealt with nearly 60,000 illegal cases with a value of more than 3 billion yuan.

　　In order to enhance the efficacy of products, some illegal enterprises illegally add drugs to harm consumers; Some merchants falsely publicize and exaggerate the efficacy, and even blow health food into a "magic medicine" to deceive consumers. At the same time, problems such as low quality of registration declaration and low-level duplication of products also bring difficulties to the review and approval work. "There is an urgent need to deepen reform and innovation, implement the strictest supervision and implement the main responsibility of enterprises." Sun Meijun, deputy director of the State Administration of Markets, said frankly.

　　According to the Measures for the Administration of Raw Material Catalogue and Health Function Catalogue of Health Foods (hereinafter referred to as the Measures) recently formulated and issued by the General Administration of Market Supervision in conjunction with the National Health and Wellness Commission, China will take the raw material catalogue and function catalogue as the starting point to standardize the scientific evaluation of raw material safety and health function of health foods, and encourage research and development of health foods with more scientific and technological content and more reliable efficacy.

　　1. The health care function of "unclear"

　　In today’s endless health care fraud, we need to re-understand health food. According to the Interpretation of People’s Republic of China (PRC) Food Safety Law, health food refers to food that claims to have health care function or aims at supplementing vitamins, minerals and other nutrients. That is, it is suitable for specific people to eat, has the function of regulating the body, does not aim at treating diseases, and does not cause any acute, subacute or chronic harm to the human body.

　　It can be seen that health food is a kind of special food between ordinary food and medicine. First of all, it is food. Secondly, it is different from ordinary food, and it has certain health care function (that is, function claim), which is the core attribute of this product. Finally, although it has health care function, it does not have the effect of treating diseases, and it is different from drugs.

　　For health food, function claim is the key, but it is very easy to fall into the predicament of exaggeration and false propaganda, and even fraud, which leads to the "magic medicine" flying all over the sky. Some experts have said that the false propaganda of health food is not all "intentional", but "unclear" by themselves. Because they didn’t make clear the functional mechanism of health food through rigorous scientific research, and lacked sufficient scientific basis, they couldn’t tell consumers exactly how healthy these health foods are and how to play their roles.

　　Are the various functions claimed by health food scientific and effective? This is the crux of the problem. It is understood that the establishment and positioning of functional claims of food and health food similar products in major countries and regions around the world mainly focus on improving health and reducing risk factors. Specifically, the classified management of health care functions generally includes three categories: nutritional component function claim, general function claim and disease risk reduction claim.

　　Among them, the function claim of nutritional components refers to the physiological activity of nutrients in human growth, development and normal function. General function claim refers to the specific function of the product for the normal function or biological activity of the human body, contributing to human health, enhancing the body function, maintaining or improving the overall health state, etc. The claim of reducing disease risk refers to the health claim that a certain food ingredient or food (food supplement) can reduce the risk of a certain disease or reduce the degree of health problems, but it cannot be equated with the role of drugs and vaccines in preventing and blocking the occurrence of diseases. For the functional claims of health food, countries generally strictly supervise it, focusing on the correlation between raw materials (ingredients), dosage and functional claims and the adequacy of scientific basis.

　　The "Measures" issued this time refer to the management of functional claims by international organizations and Europe and the United States, and make it clear that the health care function of health food in China should be aimed at supplementing dietary nutrients, maintaining and improving the health status of the body or reducing the risk factors of diseases, and also put forward the health care function guided by the traditional health care theory. "It has greatly expanded the scope of supplementing micronutrients and regulating specific body functions, and covered the health care needs of the broad masses more comprehensively." Li Keji, a professor at peking university health science center School of Public Health, said.

　　2. Whether it is effective or not depends on science.

　　To "clarify" the health care function, we must rely on scientific research. Evaluation of raw materials safety and health care function of health food and catalogue management are the important basis for the dual-track system of filing and registration and approval of health food in China. Whether it can pass the evaluation and be included in the catalogue depends on science.

　　It is understood that the catalogue of health functions stipulates the range of health functions that health foods are allowed to claim (that is, health functions that have been systematically evaluated and verified and have clear evaluation methods and judgment standards), and the catalogue of raw materials stipulates substances that can be used in health foods after safety and functional evaluation. The "Measures" are based on raw materials and functions to ensure the safety and effectiveness of health food and improve product quality.

　　In order to ensure the safety, effectiveness, true and reliable functions and stable quality standards of health food raw materials, the Measures strictly stipulate the conditions, procedures and management methods for the inclusion of the catalogue. Sun Meijun introduced that the inclusion of the raw material catalogue is based on the registration and approval of health food in China for more than 20 years and the relevant data of 16,000 registered products. It is necessary not only to review the safety, but also to clarify the dosage of raw materials and the corresponding efficacy, and focus on reviewing its scientific basis.

　　More importantly, how to ensure the scientific health care function. The "Measures" stipulate that the health functions claimed by health foods should have clear health needs and can be correctly understood and recognized; Have sufficient scientific basis, as well as scientific evaluation methods and criteria; The health care function guided by the traditional health care theory conforms to the traditional Chinese medicine health care theory; There are clear suitable people and unsuitable people.

　　Moreover, inclusion in the catalogue does not mean that it can be used all the time. "For the raw materials and health care functions included in the catalogue, a re-evaluation and exit mechanism has been set up. If the latest research finds risks and the scientific consensus changes, the catalogue adjustment procedure can be started in time." Sun Meijun said that according to the progress of relevant scientific research and the needs of food safety risk prevention and control, the catalogue of health food raw materials and the catalogue of health care functions should be dynamically managed and adjusted according to the results of re-evaluation.

　　Liu Xuecong, Secretary-General of China Nutrition and Health Food Association, believes that according to scientific research and progress, it is an inherent requirement for the development of health food industry to dynamically adjust the health care functions that can be claimed, and at the same time, allow new health care functions to be admitted, which is also to meet the growing consumer demand of the masses.

　　3. Open up innovative R&D paths

　　It is worth noting that the "Measures" have changed the management mode claimed by functions, emphasized social co-governance and encouraged R&D and innovation. In the past, the evaluation and management of functional claims of health food in China were all arranged by the government. The Measures reformed this "nanny-style" management mode, opened up the innovative R&D path of health food, changed the formulation of health function and evaluation method from a single government-led to multi-subject participation, guided and standardized functional R&D and scientific evaluation, and implemented the main responsibilities of enterprises and R&D institutions.

　　Specifically, the "Measures" open directory project formulated a model to encourage multi-market players to participate in the catalogue formulation and research and develop new health care functions. On the basis of scientific research and demonstration, any individual, enterprise, scientific research institution and social organization can put forward suggestions for inclusion in the catalogue of raw materials and functional claims of health food, and those that meet the requirements can be included in the catalogue after being reviewed and publicly demonstrated by the competent department according to the procedural requirements, so as to stimulate the enthusiasm, initiative and creativity of enterprises, scientific research institutions and social organizations in developing new materials and functions.

　　"This can give full play to the scientific research advantages of social resources, improve the scientific evaluation methods of raw materials and functions, solve the problem that the current single government is dominant and the scientific and technological strength is insufficient, improve the quality of filing products and registration applications, and improve the efficiency of evaluation and approval." Sun Meijun said.

　　In addition, the Measures also encourage enterprises to not only inherit the traditional Chinese medicine health preserving theory, but also make full use of modern biomedical technology, research and develop new products with new functions, change the current situation of low-level duplication of products, and promote the high-quality development of health food industry.

　　These measures are greatly welcomed by people in the industry. Liu Xuecong told reporters that changing the situation dominated by the government in the past and letting industry enterprises stand at the center of the stage of catalogue and function research will greatly encourage and promote the R&D and innovation of China’s health food industry.

　　The General Administration of Market Supervision said that it will stick to the safety bottom line, strengthen scientific supervision, fully consider the efficacy orientation of health food, carry out classified management according to traditional consumption history, scientific basis and risk level, strictly supervise new raw materials and new functions, and gradually expand the catalogue of raw materials and functional claims of health food.

　　4. Comprehensively clean up and adjust health care functions.

　　The frequent false propaganda and fraud of health food reflects the imperfection of current health function management. The reporter learned that the General Administration of Market Supervision has begun to comprehensively clean up and adjust the health care functions approved in different historical periods in the past, to avoid confusion with the preventive and therapeutic functions of drugs and diseases, to get to the root of the problem, and to plug the loopholes in the claim that the health care functions of health food have been falsely publicized.

　　"The 27 functions of the current health food have been used for nearly 20 years. With the progress of public cognition and science and technology, its name and label content have not been recognized by the society to a certain extent, and there are also many backwardness and deficiencies in science." Li Keji pointed out.

　　In March 2019, the General Administration of Market Supervision issued the Announcement on Soliciting Opinions on Adjusting the Health Function of Health Food, which pointed out that after organizing many demonstrations by experts in the fields of medicine, pharmacy, food and nutrition, it is planned to adjust the health function, mainly including: First, canceling the past approvals such as "tumor suppression" and "anti-mutation", which are inconsistent with the existing regulatory positioning of health food, and the products are actually easy to exaggerate and mislead, and are not in line with health needs. The second is to further study and demonstrate the health care functions such as "auxiliary blood lipid lowering" and "auxiliary protection function for radiation hazards"; The third is to adjust 18 kinds of health function claims to improve consumers’ scientific cognition and accurate judgment of health food function claims, such as adjusting "immune regulation/immunity enhancement" to "help to enhance immunity".

　　The industry believes that adjusting the claim of health care function, further defining and standardizing the source of health care function, and effectively distinguishing health food from medicine can greatly reduce the misjudgment of consumption. The reporter learned that this adjustment proposal is currently soliciting opinions from the whole society, and the General Administration of Market Supervision will also organize experts in the fields of medicine, pharmacy, food and nutrition to carefully analyze and study the collected opinions one by one.

　　Sun Meijun revealed that in the next step, the market supervision department will have a series of regulatory measures to be introduced one after another. For example, formulate advertising review management measures and strictly review health food advertisements; Orderly carry out the clean-up work of replacement; Strengthen production license review, daily supervision, supervision and sampling inspection, and system inspection; We will carry out multi-sectoral joint law enforcement, severely investigate and deal with all kinds of illegal acts, and crack down on black dens illegally added, illegally sold, and made and sold fakes, and we will never be soft.

　　However, Sun Meijun reminded: "Health food is not a necessity, and not everyone needs it. On the health food label, there are labels for suitable people and unsuitable people. Consumers should carefully choose according to their physical needs when purchasing. "(Reporter Chen Haibo)

　　foreword

　　In 1957, the Canton Fair entered the historical stage, and it was a blockbuster at the beginning of its birth — — The turnover of the Canton Fair in the first year accounted for one-fifth of the total foreign exchange earned in that year, and it was a veritable window of national trade. In the more than 60 years since that year, the venue of the Canton Fair has been moved several times, and the exhibition area has increased dozens of times. It is the long-standing strength of Guangzhou’s urban development and China’s ambition to open its doors wider and wider that has promoted the expansion of venues.

　　The newspaper’s large-scale series report "70 years and 70 years of Guangzhou landmarks" entered the fourth series of exhibition halls today. We selected four important exhibition buildings that accompanied Guangzhou’s growth and still presented them by hand drawing.

　　There are 12 issues in the series "Guangzhou Landmarks in 70 Years and 70 Years". Collect all the pages of this series and complete the puzzle in the shape of "70", and you will have the opportunity to participate in the follow-up activities.

　　The history of exhibition buildings in Guangzhou is also a history of urban construction in Guangzhou and the opening of China. From Haizhu Square, Liuhua to Pazhou, the rise of landmarks witnessed the outward expansion of Guangzhou’s urban skeleton and the eastward movement of CBD, and recorded the greater and more stable pace of China’s opening up.

　　Canton Fair, a fast-growing newborn.

　　At the beginning of the founding of People’s Republic of China (PRC), some western countries imposed "economic blockade" and "goods embargo" on China economically. Guangzhou, which is adjacent to Hong Kong and Macao, held three exhibitions and exchanges of export materials from 1955 to 1956, with remarkable results. At that time, the Commissioner of the Ministry of Foreign Trade in Guangzhou was keenly aware that the national export commodities exhibition and exchange meeting should be held here, and the request was finally approved by the central government. In November, 1956, the China Export Commodities Exhibition was held in the former Sino-Soviet Friendship Building in Guangzhou. The participating merchants came from 37 countries and regions, and the export turnover was US$ 53.8 million.

　　This exhibition is the predecessor of the Canton Fair. In 1957, the former Ministry of Foreign Trade issued a document agreeing to hold an export commodities fair in Guangzhou in April. The first Canton Fair was still held in the Sino-Soviet Friendship Building, with an exhibition area of 9,600 square meters. This Soviet-style building was completed in July 1955, and it was particularly magnificent in Guangzhou, which was in full swing at that time. The Canton Fair was held in spring and autumn, and in the first year, the turnover was 86.86 million US dollars, accounting for 20% of the total foreign exchange generated in that year. The Canton Fair held in Guangzhou has opened up a channel for new China to trade with Southeast Asia and even other countries and regions in the world.

　　As the window of new China’s opening to the outside world, the Canton Fair entered a period of rapid growth as soon as it was born, and the venue expanded again and again. Since 1958, the Canton Fair has been moved to the China Export Commodities Exhibition Hall on Qiaoguang Road in the west of Haizhu Square, with an area of 13,000 square meters, which has increased by nearly 50%, but it still seems to be somewhat stretched. Therefore, in 1959, it took only nine months to build the exhibition hall of Uprising Road (now Binbin Square) with an area of 34,500 square meters, as a "birthday gift" for the 10th anniversary of the founding of New China. In November of that year, the opening of the 6th Canton Fair was ushered in here. Only four years later, the supply of booths became tight again. In 1963 and 1968, the venues around Haizhu Square were allocated to the Canton Fair, and the exhibition area increased to nearly 50,000 square meters.

　　As one of the most important exhibitions in China at that time, the significance of Canton Fair to Guangzhou has already exceeded the scope of ordinary exhibitions, which directly promoted the development of all walks of life in Guangzhou. In the early days of the Canton Fair, the reception services for the opening and closing receptions were exclusively undertaken by Aiqun Hotel. However, with the expansion of the Canton Fair, the demand for one hotel was obviously in short supply. This directly gave birth to the famous "27 layers" — — Guangzhou Hotel, the tallest building after the founding of New China.

　　Exhibition breeds Guangzhou foreign trade buildings

　　After more than 60 years of hard work, the uninterrupted Canton Fair has demonstrated China’s firm determination to open to the outside world. In the past 60 years, Guangzhou, as the venue of the Canton Fair, has received strong support from the state.

　　In the 1970s, the problem of insufficient venue for the Canton Fair became more and more prominent, and the whole urban construction in China basically stopped. With Premier Zhou Enlai’s concern and inquiry, the "Guangzhou Foreign Trade Project" was approved, and the state allocated 60 million yuan to build Liuhua Road Exhibition Hall, Oriental Hotel New Building, Liuhua Hotel and baiyun hotel in the Canton Fair, and a towering foreign trade complex rose.

　　In 1974, Liuhua Road Exhibition Hall was put into use, with a building area of 110,500 square meters and a central air conditioning system. Here, the Canton Fair welcomed the then US Vice President George Bush, the Federal Republic of Germany President karl carstens and other international dignitaries, and more and more countries began to understand China.

　　From Haizhu Square to Liuhua Road, the Canton Fair has been held at two important nodes of Guangzhou’s traditional central axis for more than ten years, which is both a witness and a promoter of Guangzhou’s development. In 1974, Guangzhou Railway Station was completed almost at the same time as Liuhua Exhibition Hall. Together with the old Baiyun Airport, which is five or six kilometers away by car, and convenient transportation, Liuhua area has become Guangzhou’s foreign transportation hub and foreign trade center. In 1976, baiyun hotel, with a height of 114 meters, officially opened, setting a new record for the tallest building in China, just like her "brother" — — Guangzhou hotel built by the spring breeze of Canton Fair.

　　The relocation of Canton Fair gave birth to the "Golden Triangle"

　　Although the name of Canton Fair has been "Guang" for a long time, there was a voice from outside to "study the relocation". With its strength and speed, Guangzhou has proved that this city is the best choice for the Canton Fair.

　　In the 1990s, many enterprises could not enter the Canton Fair because of insufficient booths. In 1993, the Ministry of Foreign Trade and Economic Cooperation proposed to rebuild the Canton Fair exhibition hall and make it a world-class exposition. For a time, domestic star cities competed with each other and offered favorable conditions to "attract". Guangzhou, on the other hand, decided to locate Pazhou, and made it clear that the subway leading to the Canton Fair would be built in advance.

　　In 1999, Guangzhou, which finally got the reply from the national ministries and commissions, launched the international invitational competition of architectural design scheme that year. In April 2001, Guangzhou International Convention and Exhibition Center started construction, with a total construction area of over 1.1 million square meters. On December 28th, 2002, the first phase of the project was completed. This speed is unique, and the person in charge of the project is on the construction site on the third day of the year. Because the construction period is short, the consumption of building materials is large, and what kind of materials are needed for construction, there is a shortage of such building materials in the Pearl River Delta.

　　In October 2003, the Canton Fair set up a branch venue in Pazhou for the first time, and all of them moved to Guangzhou International Convention and Exhibition Center five years later. Here, the Canton Fair set a record of $74.76 billion a year and 416,000 buyers a year. Since 2007, the Canton Fair has increased its import exhibition area and renamed it China Import and Export Fair, further opening up to the world. Today, Pazhou has become an exhibition center in Guangzhou and even in South China, making it a "golden triangle" of Guangzhou together with Pearl River New Town and Financial City.

　　Looking back on the past and looking back on the history of Guangzhou’s exhibition, the exhibition area of the venue ranges from the traditional central axis to Pazhou, from 9,600 square meters to nearly 400,000 square meters, and the annual turnover ranges from 86.86 million US dollars to 74.76 billion US dollars. The Canton Fair and Guangzhou have grown together, leaving one milestone after another on the map of urban development and making irreplaceable contributions to China’s opening-up process.

　　Uprising Road Exhibition Hall (now Binbin Square, Haiyin): The piling of the Uprising Road Exhibition Hall (now Binbin Square, Haizhu Square) began in November 1958 and was completed at the end of August the following year; It took only nine months for the project, which was a gift for the 10th anniversary of the founding of New China, to welcome the opening of the 6th China Export Commodities Fair on November 1st, 1959. From 1959 to 1974, this exhibition hall held 29 sessions of Canton Fair.

　　The exhibition hall of Qiyi Road covers an area of 10,900 square meters, with a total construction area of 40,200 square meters (including ancillary buildings) and a usable area of 34,500 square meters. The middle building is 10 stories high and the west and north wings are 8 stories each. In addition to displaying the main export commodities, there are more than 70 transaction negotiation rooms on the first to sixth floors of the museum. During the opening period, there are also service desks for banks, posts and telecommunications, insurance and shipping, sample retail offices and bars on the seventh floor. The pavilion was also an integral part of Zhuhai Danxin, one of the eight scenic spots in Yangcheng at that time.

　　Liuhua Road Exhibition Hall: Liuhua Road Exhibition Hall started in October 1972 and was completed in April 1974. The nine characters of "China Export Commodities Fair" hanging on the front of the main building are handwritten by Guo Moruo. From 1974 to 2008, the pavilion and the Canton Fair spent 34 years together.

　　The exhibition hall covers an area of 98,000 square meters with a total construction area of 110,500 square meters. It is interconnected with many surrounding commercial buildings, five-star hotels and clothing commercial markets, and is adjacent to Guangzhou Railway Station, Yuexiu Park subway station and urban traffic trunk roads. It is an important distribution center for business exchanges. Since 1975, the exhibition hall has been added, expanded, renovated and decorated many times, with a total construction area of 170,000 square meters. In 1980s, the exhibition hall and the adjacent buildings such as Oriental Hotel, Liuhua Hotel and Friendship Theatre were selected as one of the eight scenic spots in Yangcheng, enjoying the reputation of "Liuhua Yuyu".

　　Guangzhou International Convention and Exhibition Center: Guangzhou International Convention and Exhibition Center is located in Pazhou Island. Construction started in April 2001 and was completed and put into use in December 2002, which lasted for 20 months. In October 2003, the 94th Canton Fair tried out some exhibition halls of Pazhou Pavilion for the first time. In April 2004, the first phase of Pazhou Pavilion of the 95th Canton Fair was put into full use. In September 2008, the 104th Canton Fair was moved to Pazhou Exhibition Hall as a whole.

　　The exhibition center covers an area of over 800,000 square meters, with a total construction area of over 1.1 million square meters, a total indoor exhibition area of 340,000 square meters and an outdoor exhibition area of 43,600 square meters. It was a modern exhibition hall with the most advanced facilities and complete functions in Asia at that time. Looking down from a height, it is like a white cloud fluttering on the river. The design concept of the convention and exhibition center comes from the "floating" of the Pearl River, and the undulating roof makes it seem to fly from the Pearl River.

　　Baiyun International Conference Center: Guangzhou Baiyun International Conference Center started construction in October 2005 and was completed in March 2007. It is located in the middle of Baiyun District, east of Baiyun Avenue, facing Baiyun Mountain National Scenic Area, west of Airport East Road, the former site of Baiyun Airport, and south of Guangzhou Gymnasium.

　　Baiyun International Conference Center covers an area of about 250,000 square meters. The main building includes three conference and exhibition centers and two supporting hotels, including more than 100,000 square meters of conference venues and nearly 20,000 square meters of exhibition venues. The conference hall, supporting facilities and hotels stand in parallel in the north and south, forming a unique "visual corridor" while effectively reducing the impact of direct sunlight on the room.

　　Expert perspective Guangzhou International Convention and Exhibition Center is so "floating"　　

　　Ni Yang: Dean of Architectural Design and Research Institute of South China University of Technology

　　Guangzhou International Convention and Exhibition Center, floating on Pazhou Island, is like a warm wind blowing to the south bank of the Pearl River. In 1999, the international bidding for architectural scheme design was launched, and the scheme from Japan "floated" to the Pearl River. From the initial "sticking to the ground" design to the light "floating" now, it is behind the repeated optimization and polishing by the Chinese and Japanese designers. Construction started in 2001, and the first phase was delivered in 2002. Up to now, after 17 spring and autumn periods, this building at the turn of the century is still a landmark of exhibitions in Guangzhou and even South China.

　　In 1999, Guangzhou International Convention and Exhibition Center publicly solicited architectural design schemes for the whole world. The competition lasted for three months, and then after 40 days of optimization design, all parties concerned finally chose the scheme of Sato Comprehensive Plan in Japan. The Tokyo BIG SIGHT, which was completed in November 1995, was created by this company and is still the largest exhibition venue in Japan.

　　The concept of the scheme proposed by Sato of Japan for Guangzhou International Convention and Exhibition Center is "gone with the wind", which is like a warm river wind blowing to Pazhou Island, and the design is light and elegant. The streamlined exhibition hall is high in the south and low in the north, and there is one less exhibition hall facing the north side of the Pearl River. The wavy roof is naturally connected with the green land. At the beginning, an open hydrophilic park was arranged along the Pearl River on the north side of the land, which introduced the river water to form fountains and waterfalls, forming a landscape of "canals" and "bridges".

　　As a cooperative designer in China, the Architectural Design and Research Institute of South China University of Technology is responsible for the construction drawing design, which is equivalent to putting a romantic design plan on the ground and meets the economic and practical needs. Dean Ni Yang said: "We made the most important optimization, that is, we lifted the building, and the original exhibition hall ‘ Post ’ On the ground, the underground space is only 2.2 meters, and only some pipeline equipment can be put. We decided to increase the bottom plate and raise the pillars in the basement to 4.8 meters, which suddenly increased the underground space by 130,000 square meters. "

　　From the functional point of view, more than 4,000 indoor parking spaces have been added to the 130,000 square meters, which not only transferred the original outdoor parking spaces to the underground, but also released the external green space, and provided the center with a dining area of tens of thousands of square meters. After the underground space is heightened, the equipment center originally located 300 meters outside the exhibition hall can be moved into the building, which greatly shortens the length of water, electricity and other pipelines, reduces the energy loss, and is also convenient for pipeline maintenance.

　　"From an economic point of view, the cost of raising the building is not high. When the total cost is only slightly increased, the usable area is greatly increased, and the average cost is significantly reduced, which plays a very positive role in the overall balance of payments." This is a very high cost-effective adjustment. "From the aesthetic point of view, after the elevation, the building is more ‘ Gone with the wind ’ The beauty. " Ni Yang said.

　　People’s feelings, high-end exhibition venues are integrated into citizens’ daily lives.

　　Huang Yimin

　　Former photojournalist

　　Huang Yimin is an "old Guangzhou" who has lived and worked in Guangzhou for decades. He recalled that the first time he saw the Canton Fair was the old China Export Commodities Fair in Haizhu Square. "At that time, I saw the appearance of this building, which was eight stories high and very large. However, during the fair, ordinary people will not be allowed to visit. "

　　Later, the Canton Fair Pavilion was moved to Liuhua Exhibition Center, "‘ China Export Commodities Fair ’ The golden characters embedded in the long rows of glass curtain walls are very imposing, and a Soviet building in the 1950 s is still wrapped inside. When entering the hall, you can see the huge Soviet-style arched exhibition hall on the front. " He recalled.

　　With the continuous expansion of trade scale, the Canton Fair has been moved to Pazhou Convention and Exhibition Center in 2008, and Liuhua Exhibition Center has also been given a new mission — — Create "Old Guangjiao IP Silicon Valley". According to Huang Yimin, who has recorded Guangzhou for decades with a camera, it is an inevitable trend for Guangzhou’s convention and exhibition economy to settle in Pazhou, which shows that the economic strength of Guangzhou and even China is constantly increasing. "Exported goods go abroad and are increasingly welcomed by foreign countries. The Liuhua Road Canton Fair has condensed a precious historical memory. "

　　Ouyang Xiao

　　Neighborhood near Guangzhou New Gymnasium

　　"When Baiyun International Conference Center first opened, this area was quite desolate." Ouyang Xiao, an old neighborhood who has lived nearby for nearly 15 years, recalled that when he first moved here, there were not many people nearby. After Baiyun Airport moved away, there were still people growing vegetables in the open space left behind. "Looking around, the most conspicuous building is the Ferris wheel of Oriental Paradise."

　　In 2004, the Oriental Paradise was closed for demolition. "After the Ferris wheel disappeared, a conference center was built in this area in a few years." At that time, seeing the Baiyun Conference Center with five main buildings arranged in the north and south, Ouyang Xiao said, "I feel that this magnificent conference center is very high-end, and its main color is crimson, which looks solemn."

　　Slowly, Ouyang Xiao found in his life that the conference center is not only a high-end venue for holding exhibitions and conferences, but also has been integrated into the daily life of residents. She said that the conference center is adjacent to Baiyun Mountain, and the air is also very good. "After the vehicles coming to the conference in the evening leave, we will come here for a leisurely walk after dinner, and walk around for almost half an hour, which is very comfortable." Ouyang Xiao told reporters that by the end of the week, there were still many children flying kites here in the West Square, and many tourists coming down from Baiyun Mountain went straight to the restaurant in the conference center to have a meal and rest. "It carries many functions of leisure and entertainment for nearby residents, and it is very kind to look at it."

　　Wu Yan

　　Representatives of exhibitors from Guangzhou Hutou Battery Group

　　Since graduating from university in 2001, Wu Yan has participated in the Canton Fair for 18 consecutive years. Witnessed the historic moment when the Canton Fair moved from Liuhua Exhibition Center to Pazhou Convention and Exhibition Center as a whole. She believed that the biggest change before and after was that the professionalism of the exhibition was greatly improved: "The participating enterprises were carefully divided according to the industry to which the specific products belonged, and they all belonged to a unified area."

　　Compared with Liuhua Exhibition Center before the relocation, Wu Yan said that Pazhou Exhibition Center has a more modern architectural style, a larger exhibition hall and more brand booths: "Before attending the Canton Fair, our company shared a booth with another enterprise of the Light Industry Group, and now our company rented eight booths separately."

　　Wu Yan said that transportation also reflected the improvement of the professionalism of the Canton Fair after moving to Pazhou Convention and Exhibition Center. "Compared with the Liuhua period, the subway here is more developed, and the vehicles for the exhibition are directly driven to the exhibition hall, which is much more convenient."

　　The party’s leadership system is the fundamental leadership system in China. The Fourth Plenary Session of the 19th CPC Central Committee focused on "upholding and improving the Party’s leadership system, improving the Party’s scientific, democratic and legal governance", and clearly put forward six requirements, namely, establishing the system of Do not forget your initiative mind, keeping in mind the mission, improving the systems of firmly safeguarding the authority of the CPC Central Committee and centralized and unified leadership, improving the Party’s overall leadership system, improving the systems of governing for the people and relying on the people, improving the system of improving the Party’s ruling ability and leadership level, and improving the system of comprehensively and strictly administering the Party. These six specific systems not only have their own specific rich connotations, but also are interrelated and complementary to each other. They are closely woven from the aspects of ideological basis, system guarantee, coverage, value orientation, capacity support and self-revolution. Only by understanding its scientific connotation as a whole and grasping its internal logic can we continuously improve the comprehensive effect in practice, thus giving full play to the greatest advantage of the party’s leadership and continuously promoting the modernization of the national governance system and governance capacity.

　　Lay the ideological foundation

　　Establishing the system of Do not forget your initiative mind and keeping in mind the mission is conducive to promoting the whole party to abide by the party’s nature, purpose, ideals, beliefs and goals, and laying an ideological foundation for upholding and improving the party’s leadership.

　　It is our party’s distinctive feature and glorious tradition to pay attention to building the party ideologically and strengthening the party theoretically. The initial intention and mission of seeking happiness for the people of China and rejuvenation for the Chinese nation embodies the Communist Party of China (CPC)’s nature, purpose, ideals, beliefs and goals, and is based on Marxist scientific theory. Only by persisting in building the Party with ideology and strengthening the Party with theory can Do not forget your initiative mind be more conscious and take on a more firm mission. At present, our party has gone through the course of nearly a hundred years. Under the long-term ruling condition of the Party, various factors weaken the Party’s advanced nature and damage the Party’s purity all the time, and all kinds of dangers that violate the initial intention and mission and shake the Party’s foundation are everywhere. The outstanding problems existing in the Party, such as impure thoughts, impure politics, impure organization and impure style of work, have not been fundamentally solved. Only by establishing the system of Do not forget your initiative mind and keeping in mind the mission, persisting in building the Party with thought and strengthening the Party with theory, arming the mind with the Party’s innovative theory, and taking Do not forget your initiative mind and keeping in mind the mission as the eternal task of strengthening Party building and the lifelong task of all party member and cadres, can we further consolidate the Party’s leading position and ruling foundation, so that our Party will always be supported and supported by the people and write about the great achievements of the Chinese nation.

　　Build a strong institutional guarantee

　　Perfecting various systems that firmly safeguard the authority of the CPC Central Committee and centralize and unify leadership is conducive to promoting the effective implementation of the party’s leadership in all work and building a solid institutional guarantee for upholding and improving the party’s leadership.

　　The key to upholding the party’s leadership is to uphold the authority of the Party Central Committee and centralize and unify leadership, which is the highest principle of the party’s leadership. In the big chess game of the national governance system, the CPC Central Committee is the "handsome" in the military account. Only by upholding the authority of the CPC Central Committee and centralized and unified leadership can we ensure that the CPC Central Committee plays a leading role of "handsome". Throughout the development of the party in the past century, it can be seen that when the whole party firmly safeguards the authority of the CPC Central Committee and centralizes and unifies leadership, the party’s cause will continue to win; Without the authority of the CPC Central Committee and centralized and unified leadership, the party’s leadership will inevitably weaken and the party’s cause will inevitably suffer setbacks. The sharp contrast between "the rule of China" and "the chaos in the West" highlighted in the answers to the COVID-19 epidemic exam shows that upholding the authority of the CPC Central Committee and centralized and unified leadership cannot be vague and unshakable at any time and under any circumstances. Firmly safeguarding the authority of the CPC Central Committee and centralizing and unifying leadership requires both a high degree of consciousness of the whole party and a sound and perfect system as a guarantee. By perfecting the system of implementing the "two maintenances", improving the leadership system of the CPC Central Committee for major work, improving the mechanism of promoting the implementation of major decisions of the CPC Central Committee, strictly implementing the system of asking for instructions and reporting from the CPC Central Committee, and improving the centralized and unified organizational system for safeguarding the party, we can ensure the smooth implementation of the party Central Committee’s decrees and decisions, and ensure that the whole party is United and in step. This provides a strong institutional guarantee for better playing the core role of the party’s leadership.

　　Clear coverage

　　Perfecting the party’s overall leadership system is conducive to ensuring that the party always takes the overall situation and coordinates all parties, and defines the coverage for upholding and improving the party’s leadership.

　　The General Secretary of the Supreme Leader pointed out that "the leadership of the Party must be comprehensive, systematic and holistic, and must be reflected in economic construction, political construction, cultural construction, social construction, ecological civilization construction, national defense forces, reunification of the motherland, diplomatic work, party building and other aspects. Which field, which aspect and which link are missing and weakened will weaken the party’s strength and damage the cause of the party and the state. " This shows that the party’s leadership must be embodied in all aspects of governing the country and the activities of various organizations at all levels. In view of the weakening of the party’s leadership in some fields to varying degrees, we need to ensure the full coverage of the party’s leadership from the system. Improve the party’s overall leadership system, improve the working system of party committees (party groups) at all levels, improve the specific system of party leadership in various undertakings and the functional system of party and state institutions by improving the systems of party leaders, governments, CPPCC, supervisory organs, judicial organs, procuratorial organs, armed forces, people’s organizations, enterprises and institutions, grassroots mass autonomous organizations and social organizations. So as to ensure that the party plays a leading role in various organizations, implement the party’s leadership in promoting the overall layout of the "five in one" and coordinating the promotion of the "four comprehensive" strategic layout, and implement it throughout the whole process of the party and all state institutions performing their duties.

　　Indicate the value orientation

　　Perfecting various systems of governing for the people and relying on the people is conducive to consolidating the class foundation and mass foundation of the party’s governance and pointing out the value orientation for upholding and improving the party’s leadership.

　　Who is in power and who is in power is a problem that any ruling party must face, and it is also the touchstone to judge whether a political party is a Marxist political party. Our party has always maintained flesh-and-blood ties with the people, insisting on doing everything for the people and relying on them to govern the country. Whether ruling for the people or relying on the people, its focus is always around the "people", reflecting the people-centered value orientation. Governing for the people and relying on the people is not an empty slogan, but has concrete and practical content, which requires our party to actively practice in the process of governing and make scientific arrangements from the system. By improving the system of party member and cadres contacting the masses, innovating the mass work mechanism in the Internet era, and improving the mass work system with extensive contacts and serving the masses, the systems of governing for the people and relying on the people will be gradually improved and organically unified to ensure the people’s dominant position in state governance, which is of great significance for continuously consolidating the class foundation of the party’s governance and planting the mass foundation of governance.

　　Provide capacity support

　　Perfecting the system of improving the party’s ruling ability and leadership level is conducive to adapting to the new era and new requirements and providing capacity support for upholding and improving the party’s leadership.

　　The key to China’s success lies in the Party. At present, the domestic and international environment has undergone profound changes, and the task of comprehensively deepening reform is arduous. The party’s ruling ability and leadership level directly determine and affect the ability and effectiveness of governing the country. The General Secretary of the Supreme Leader clearly pointed out that "our Party should be politically competent as well as technically competent". The purpose of perfecting the system of improving the party’s ruling ability and leadership level is to organically unify the construction of the party’s long-term ruling ability with the improvement of the national governance level, and improve the party’s ability to take the direction, seek the overall situation, formulate policies and promote reform by adhering to democratic centralism, perfecting the relevant system of developing inner-party democracy and implementing correct centralization; By improving the decision-making mechanism, the level of scientific decision-making, democratic decision-making and legal decision-making of leading bodies at all levels will be enhanced; Enhance the political function and organizational power of party organizations at all levels by improving the party’s leadership and governance style; By improving the incentive mechanism of taking responsibility, we can improve the ruling ability and ability of leading cadres at all levels and make the party’s leadership more suitable for the requirements of practice, the times and the people.

　　Promote self-revolution.

　　Perfecting the system of strictly administering the Party in an all-round way is conducive to continuously promoting the Party’s self-revolution and ensuring that the Party will always be the strong leadership core of Socialism with Chinese characteristics’s cause.

　　Our party must always be the pioneer of the times and the backbone of the nation, and always be the ruling party of Marxism, and it must always be excellent. The General Secretary of the Supreme Leader pointed out: "If the Party is poorly managed and lax, and the outstanding problems within the Party that are strongly reflected by the people are not solved, then our Party will lose its ruling qualification sooner or later and will inevitably be eliminated by history." Therefore, to strengthen the party’s leadership, we must be strict with the word, put strict requirements through the whole process of managing the party and the party, and constantly promote the comprehensive and strict development of the party. To promote the comprehensive and strict administration of the party, we must not only solve ideological problems, but also rely on systems. The purpose of perfecting the system of strictly administering the Party in an all-round way is to persist in administering the Party according to regulations, improve the system of managing cadres, selecting talents and appointing people, and improve and implement the responsibility system of strictly administering the Party in an all-round way, so as to carry out the great self-revolution of strictly administering the Party in an all-round way to the end, continuously enhance the Party’s creativity, cohesion and combat effectiveness, and continuously improve the Party’s level of governing the country.

　　Ankylosing spondylitis is a common autoimmune disease. Because of its high disability rate and high recurrence rate, it is known as "immortal cancer". There are about 4 million patients with ankylosing spondylitis in China, and the peak age of onset is 20 ~30 years old. Patients often have to endure long-term pain and treatment pressure. Today, I will know what ankylosing spondylitis is with you and share my treatment experience.

　　Ankylosing spondylitis mainly invades the sacroiliac joint, spine, soft tissue adjacent to spine and peripheral joints, and may be accompanied by extra-articular manifestations such as eyes, intestines, heart and lungs. At the early stage of the disease, patients will have symptoms such as low back pain or stiffness, alternating pain in hips, buttocks or thigh roots, which are often confused with diseases such as lumbar muscle strain and rheumatoid arthritis. With the development of the disease from lumbar spine to chest, neck and spine, there will be problems such as pain, stiffness and limited movement. In the late stage, there will be serious disabilities such as spinal deformity, hunchback and difficulty in walking. At present, there is no explanation that can clarify the cause of ankylosing spondylitis, and we can only think that it may be caused by genetic basis, infection and other factors.

　　In life, it is not difficult to confirm whether you have ankylosing spondylitis, which can be diagnosed by common clinical methods. First, blood test, because ankylosing spondylitis is an immune disease, blood can be drawn for HLA-B27 gene testing, and if it is positive, it is basically diagnosed; The second is imaging diagnosis, making X-ray or magnetic resonance of sacroiliac joint (the position where the two sides behind the buttocks are raised and the spine and pelvis are connected).

　　In addition to medical examination, you should also be vigilant if the following situations suddenly appear:

　　1. Morning stiffness means getting up in the morning and finding that the spine is stiff, which will improve after the activity;

　　2. In addition to the waist, the chest, back and neck feel stiff;

　　3. Peripheral joint pain and even swelling, the younger the onset age, the more obvious the peripheral joint involvement;

　　4. Different from the low back pain caused by strain, the pain will last for more than 6 weeks instead of being relieved after rest;

　　5. The symptoms of low back pain are more obvious at night, and will be relieved after getting up.

　　At present, there is no radical cure for ankylosing spondylitis, and drugs are mainly used in clinic, such as non-steroidal anti-inflammatory drugs, anti-rheumatic drugs, glucocorticoids and biological agents. If patients can get timely diagnosis and reasonable treatment, they can relieve symptoms and improve prognosis, and get the same life function as normal people.

　　In addition, ankylosing spondylitis is a chronic disease, and patients should pay attention to nursing in life besides actively cooperating with doctors in standardized medication and treatment.

　　1. Insist on exercise. Patients can usually do stretching and balancing exercises, or they can do whole-body exercises, such as swimming. The amount of exercise varies from person to person and should be gradual.

　　2. No matter walking or standing, keep a normal posture, sit upright and stand upright, and pay attention to keeping your chest out and your back straight to prevent spinal deformation.

　　3. It is not advisable to sleep in a soft bed, but in a hard bed to keep the normal shape of the spine.

　　In daily life, we must not be careless about these seemingly minor symptoms of low back pain. We should check, prevent and treat them early. We must not blindly treat them and miss the best treatment period.

Speaking of 120, everyone knows it is an emergency hotline, but do you know how to communicate with the dispatcher in case of emergency? What can be done in the process of waiting?

Today, Xiaobian will talk to you about those things about 120 ~

When can I call 120?

As a life-saving first aid channel, the number of 120 patients is still huge, especially when some disasters occur. Therefore, each of us should learn when to call 120 and how to call 120, so as to minimize the unnecessary occupation of emergency resources and improve the efficiency of asking for help.

The following eight situations occur, so be sure to dial 120.

(1) Sudden heart attack, such as severe arrhythmia, myocardial infarction, angina pectoris, acute heart failure, etc.;

(2) Shock or collapse, such as pale face, cold sweat dripping, weak pulse frequency, and decreased blood pressure;

(3) cerebrovascular accidents, such as loss of consciousness, coma, stroke, hemiplegia, etc.;

(4) massive hematemesis and hemoptysis;

(5) Severe dyspnea or asphyxia, such as foreign body blocking the respiratory tract;

(6) All kinds of acute poisoning, such as food poisoning, drug poisoning, pesticide poisoning, taking poison, etc.;

(7) Unexpected disasters, such as lightning, drowning, electric shock, traffic accidents and other industrial injuries, trauma, civil collapse and extrusion;

(8) Other conditions that may endanger the patient’s life, such as severe burns and frostbite.

If the patient does not have the above eight serious conditions, but his condition or injury tends to deteriorate, he should also call 120 for help in time.

# Tips #

Never think that it will be faster and more convenient to drive the patient to the hospital than to call an ambulance!

120 Emergency personnel will give patients some emergency rescue and diagnosis before the hospital, and report to the hospital, which is convenient for the hospital to prepare for receiving doctors. The medical equipment on the ambulance can also rescue patients in emergencies.

At the same time, when the ambulance is in danger, it will sound an alarm, and social vehicles will pay attention to giving way, so as to facilitate the patient to be sent to the hospital as soon as possible.

So, next, Xiaobian will tell you what to pay attention to when dialing 120 ~

What should I pay attention to when dialing 120?

Xiaobian first gives you a wrong example:

"My grandfather fell to his head! Come quickly! "

"Ok, what’s the address?"

"My community, send someone quickly!"

"Excuse me, where is your community?"

"Beeping …"

Do you think this is a bit exaggerated? Don’t believe it, this is what really happened.

Although the emergency center can get the exact location through mobile phone positioning, it also delays the emergency time. So what is the correct method?

Knowing the correct way to dial 120, I believe many friends still have questions: "Which hospital can I choose for the 120 ambulance?" "Do you want to charge?"

How is 120 allocated?

1 Distribution system

Generally speaking, ambulances are commanded and dispatched by the 120 Command and Dispatching Center, which uniformly allocates the emergency resources of the whole city and treats emergency patients in different levels and districts. In the case of unstable patients’ condition, it is not allowed to designate hospitals for the first aid.

PS: If the patient’s condition is stable, there are no special circumstances that can be sent to the designated hospital according to the wishes of the patient or his family.

2 charging system

As a special vehicle equipped with professional medical equipment and emergency personnel, ambulances are not free of charge and are not covered by medical insurance reimbursement.

Ambulance expenses generally include two parts: ambulance expenses and pre-hospital first aid expenses.

Ambulance fee

The ambulance fee includes a fixed use fee (starting price) plus a kilometer fee. In case of waiting for a bus, a waiting fare will be charged.

Take Fuzhou Traditional Chinese Medicine Hospital affiliated to Fuzhou University of Traditional Chinese Medicine as an example;

The charge for an ambulance within 3 kilometers is 200-300 yuan, and for each additional kilometer, the charge is 8-10 yuan, and the part less than one kilometer is counted as one kilometer.

(The local regulations are slightly different. The local regulations shall prevail.)

Pre-hospital first aid fee

Pre-hospital emergency expenses refer to all kinds of expenses incurred by a series of first aid, medicines and medical supplies before being sent to the hospital.

Some cities will also charge stretcher fees according to elevator rooms or staircase rooms, and the fees on different floors are also different.

Xiaobian reminder

These fees are uniformly stipulated by local provinces and cities, and all fees are based on standards, which are not casually mentioned by hospitals, so you don’t have to worry too much!

After making an emergency call, it always feels like a long time to wait for an ambulance. What else can we do for the patients during the waiting process?

Now you know that 120

How to call and how to charge?

Titanium media note:This article comes from WeChat WeChat official account Netease Digital Reading (ID: datablog163), by Su Wanshui, authorized by Titanium Media.

After Luo Min, the originator of campus loan, invited Jerry and Fu Seoul to bring prefabricated dishes, the prefabricated dishes caused a new round of controversy. In mid-September, in the "Oriental Selection" live broadcast room, the founder of Zhigang think tank shouted that "prepared dishes are pig and dog food".

Prefabricated dishes, a term that has a sense of existence in this year’s public opinion field, refer to semi-finished dishes that are prepared in advance and can be eaten simply by heating or frying later.

Precast dishes have been blown to the air, and "kitchen black holes" have found "spring" for cooking, but some people have a slight complaint — — This kind of fast food, which runs counter to the traditional eating habit of focusing on freshness, will eventually make Chinese food lose its soul and change the taste buds of Chinese.

When consumers feel that life is surrounded by something, capital with a keen sense of smell must have swarmed, just like prefabricated dishes.

There is no doubt that in the past two years, the industry of prefabricated vegetables has really caught fire. According to NCBD data, in 2021, the scale of the prefabricated vegetable industry will exceed 300 billion [1], and even some institutions predict that it will be a trillion-dollar track [2].

Among the players in the pre-cooked food track, whether they are cooking home-cooked dishes, focusing on vegetables, focusing on seafood, western food or hot pot and other special dishes, or even doing supply chain, they are all favored by investment institutions.

According to our statistics, from 2021 to the first half of 2022, there were at least 56 investment and financing events of prefabricated vegetables, accounting for 17% of the 334 public financing events in the catering industry during the period [3] [4].

Among them, tens of millions of levels of financing are the mainstay, but there are also billions of dollars in business. For example, in March of this year, Lu Zhengyao, who left Ruixing, participated in the establishment of the Tip of the Tongue Hero, and received 1.6 billion Series B financing [5].

In January of this year, the Tip of the Tongue Hero was officially launched, claiming that it would open 5,000 stores this year. Although there were only over 400 stores in July, people from all walks of life always paid close attention to whether the Tip of the Tongue Hero could become a lucky star in the catering industry [6].

According to the statistics of China Chain Store & Franchise Association, the amount of financing flowing into the prefabricated vegetable industry in the past year and a half can account for 10% of the financing amount of the catering industry [7]. "Prefabricated dishes" can also be compared with "meta-universe" and "carbon neutral", and together with them, it will become the most concerned track for investment institutions in the first half of 2022 [8].

Capital is willing to invest, and provincial policies are also overweight. Under such a good environment, there are more players on the track, and the start-ups, transformations and cross-border competitions are on the same field. By April 2021, Weizhixiang was listed, and the "first stock of prepared vegetables" in A shares successfully ran out.

In the year of 2021, Weizhixiang achieved revenue of 765 million yuan, up 23% year-on-year, and at the same time, 133 million net profit was returned to the mother, up 6% year-on-year [9].

Making prefabricated dishes can really make money. In fact, Weizhixiang, whose market is concentrated in East China, has achieved double growth in revenue and net profit in recent years. In the first half of 2022, the operating income of Weizhixiang reached 378 million yuan, and the net profit returned to the mother increased by 14.58% year-on-year.

Like the tip of the tongue hero, Weizhixiang also focuses on retail channels. In the first half of 2022, there were 1,522 franchise stores and 645 cooperative dealers nationwide [10].

If you often go to the vegetable market, you may be familiar with Weizhixiang, because the retail channels of Weizhixiang are mostly distributed in various vegetable markets and farmers’ markets. It is in the vegetable market that the founders Xia Jing and his wife observed the pain points of office workers’ trouble in washing vegetables and made their fortune [11].

But at the same time, Wei Zhixiang is also trying to walk on two legs, expanding the business of wholesale and direct sales to catering enterprises, and selling half of the dishes to hotels, restaurants, etc. In the first half of 2022, the revenue of wholesale channels accounted for 26.35% [12].

This is because consumers’ buying habits of prefabricated dishes are still in the training stage, but the use of prefabricated dishes in restaurants has already matured.

In recent years, prefabricated dishes have caught fire, and many people have also appeared in their homes. But in fact, prefabricated dishes have already "invaded" chain restaurants.

"28 separation" is the actual situation of this industry — — The ratio of B-end market to C-end market is about 8:2. According to China Chain Store & Franchise Association, at present, more than 85% of the sales channels of prefabricated vegetables are concentrated in B-end [7].

In other words, most of the prepared dishes flow to the central kitchen of the restaurant, and after being processed by the central kitchen, the prepared dishes in the form of semi-finished products continue to be delivered to various stores and finally delivered to the diners’ tables.

In 2020, 68.3% of the chain catering brands with more than 10 stores are already using the central kitchen [13].

In the survey of China Chain Store & Franchise Association, the proportion of prepared food in some head Chinese fast food companies can be close to 100%, such as Kungfu, while the proportion of prepared meals in Xibei Youmian Village and Xiaonanguo has reached more than 85% [7].

Moreover, compared with in-house food, take-away food is the growth soil of prefabricated dishes, and meals can be served simply by stir-frying, so merchants can not worry about overtime. The braised pork rice or pickled fish you ordered for lunch is probably a heated frozen fast food.

Pre-cooked dishes, a standardized product, are a perfect match with chain restaurants that pursue scale and take-away industries that pursue timeliness. The chain rate of restaurants in China is increasing, and the proportion of online take-out industry in the catering industry will reach 21.4% in 2021.

It can be predicted that as chain restaurants and takeout become more and more common, diners will be more likely to eat prefabricated dishes.

Why are prefabricated dishes so popular with chain restaurants? The reason is that prefabricated dishes can help them achieve "reducing costs and increasing efficiency".

Through the central kitchen, we can ensure the uniformity of products and reduce the risk of quality control, and the speed of eating will be accelerated, and we can entertain more guests in fixed business hours, and the revenue will naturally increase.

On the other hand, using prefabricated dishes, the kitchen in the back of the store heats it up and simply stirs it, which eliminates the need for chefs to operate, and the required manpower is also reduced, which greatly saves labor costs.

According to the calculation of China Chain Store & Franchise Association, the labor cost of restaurants will be reduced from 22% to 10% before and after using prefabricated dishes. Although the cost of raw materials will increase to some extent, the overall profit will still increase.

If it is a takeaway, the kitchen area can be further reduced and the rent cost can be lowered.

High rent and high labor are two big problems in the catering industry, both of which are solved by prefabricated dishes.

No wonder jian li, the founder of Xin Spicy Road and the chairman of Xinliangji, published bold opinions on his short video account that "in the next 10 years, 90% of chefs will be killed by prepared dishes" and "in the next 10 years, 90% of restaurants must use prepared dishes" [14].

Under the domination of assembly line production, the role of Chinese chefs has indeed been greatly reduced. If the taste is good, the power will be vested in the preparers of prefabricated dishes, and only a small number of chefs can get this "honor", while a large number of ordinary cooks know how to turn on and off the fire.

China Newsweek once reported that a 45-year-old skilled chef lost his job because his owner chose a new location in a shopping mall that restricted the use of open flames. "It may only take two minutes to heat up the prefabricated material package in 5 yuan and sell it in 25 yuan. From this point of view, the boss really doesn’t need to raise me again "[15].

Catering enterprises reduce costs and increase efficiency, but consumers are not willing — — Isn’t it the original intention of us to go to the restaurant all the way to eat the fresh and hot dishes cooked by the chef, even if there are occasional flaws?

The taste of the prepared dishes is mostly the same, and diners eat too much, and they slowly taste the clues.

In the first half of this year, "the use of prefabricated dishes in take-out and in-house meals without telling customers" became a widely complained problem, and the China Consumers Association criticized it by name, pointing out that it damaged consumers’ right to know and choose [16].

In August this year, CCTV’s Tianxia Finance reported that over 80% of chain restaurants in Guangzhou use prefabricated dishes [17], while in Shanghai, the users of prefabricated dishes even include Michelin restaurants [18].

After hearing this, a group of gourmets were thunderstruck, and related topics on social media were filled with their anger and disappointment.

The hottest controversy is that "prefabricated dishes unify the taste of restaurants". As prefabricated dishes continue to "invade" restaurants, different restaurants taste the same and have no pot gas.

Some people accuse restaurants of eating too ugly, and consumers pay the price of fried food. As a result, they get cheap fast food on the heating line, which is obviously unacceptable to consumers.

Indeed, if you go out for a meal, you can’t eat fresh ingredients and the chef’s unique skills. Anyone feels that he is a "big injustice". To suffer such a crime, it is better to order takeout or make instant noodles by himself.

When it comes to family use scenarios, solitary people who have "one person to eat" are too lazy to cook or young couples who "support their feet" want to eat some new tricks, and they may not be able to make cheap, delicious and relatively healthy meals with the help of prefabricated dishes.

They are not cheap — — Over 70% of consumers will choose to buy pre-cooked dishes above 21 yuan, and more than 14% will spend more than 40 yuan.

And they may not be so healthy — — A 258-gram prefabricated dish contains more than 2600 mg of sodium, which is too high [19].

Of course, these security risks may be solved with the improvement of industry norms, and the categories and tastes of high, medium and low-end markets will be richer and the prices will be more reasonable.

The emergence of prefabricated vegetables is the product of market demand, and the pace of life in modern society is fast. It is really convenient for many "workers" who don’t have enough time to wash vegetables, chop meat and marinate for seasoning.

However, it has always been lamented that when one day, the family kitchen is deeply invaded and the catering industry is heading for assembly line production in an all-round way, private and fresh delicacies will decline, and the "mother’s taste" will be nowhere to be found. The non-standardized and attractive Chinese food has also been eroded by industrial civilization.

No one hopes that the next "eat drink man woman" will not have the eighteen martial arts of steaming, frying, boiling, stewing and stewing, which are pleasing to the eye of Lao Zhu, but only the fancy way of tearing the packaging bag of prefabricated vegetables; Or the next "Gourmet" doesn’t have golden wisps of Buddha clothes, roasted geese in Gankun, and ecstasy rice, but only pre-made barbecued pork rice with heating time in place.

Cctv news(News Network): "Going into the County to See Development" entered Zizhong County, Sichuan Province today (August 15th). Since the 18th National Congress of the Communist Party of China, Zizhong has promoted agriculture through science and technology, strengthened the characteristic agricultural industry, and strived to build a strong county with characteristic industries in Chengdu and Chongqing.

Zizhong County, Sichuan Province, is located in the middle of Sichuan Basin, and it is the time for local rice harvest. Since the 18th National Congress of the Communist Party of China, Zizhong has carried out the strategy of "storing grain on the ground and storing grain in technology", continuously explored the land potential, and tried to implement whole-process mechanized farming in hilly areas to promote grain production and income.

Yi Xiaojie, a rice grower in Zizhong County, Sichuan ProvinceMechanized farming has been carried out throughout the process, and the output has also gone up, and our pockets have also swelled.

Promoting agriculture through science and technology and promoting the high-quality development of modern agriculture. Relying on national agricultural science and technology parks, national modern agricultural industrial parks and national rural industrial integration development demonstration parks, Zizhong has continuously increased investment in research and development, and the scale and quality of agricultural products have been continuously improved. In 2021, the total output value of Zizhong agriculture was 8.131 billion yuan.

Zizhong is located between Chengdu and Chongqing. In recent years, the local transportation infrastructure has developed rapidly. Now, from Zizhong North Station, Chengdu-Chongqing high-speed railway can reach the capital in 28 minutes and Chongqing in 38 minutes. In the future, Zizhong will continue to lay out emerging industries such as clean energy and electronic information, build food and beverage industry clusters, and strive to build a strong green industry county in Chengdu and Chongqing, relying on the development of the twin-city economic circle in Chengdu and Chongqing.

Lu Songming, Deputy Secretary of Neijiang Municipal Committee of Sichuan Province and Secretary of Zizhong County CommitteeWe will develop characteristic agricultural industries, actively undertake supporting key industries in Chengdu and Chongqing, speed up the construction of a regional modern logistics system, and integrate high-quality into the twin-city economic circle in Chengdu and Chongqing.

　　According to the latest data released by the Ministry of Commerce of China, the actual amount of foreign capital used in China in the first month of the year was 127.69 billion yuan, up by 14.5% year-on-year. The scale has steadily increased and the structure has been continuously optimized, which shows that China is still a hot spot for foreign investment. International organizations and foreign-funded enterprises in China have expressed their optimism about China’s economic development prospects, believing that China’s economy will make generate more dynamic and bring more market opportunities and development dividends to the world.

　　In January this year, Standard Chartered Bank was granted permission to set up a wholly foreign-owned securities company in China, becoming the third wholly foreign-owned securities company approved after JPMorgan Chase Securities and Goldman Sachs Gaohua Securities. "China unswervingly promotes high-quality development, deepens reform and opening up, and especially continues to promote financial opening up on a higher level, which provides huge development opportunities for foreign financial institutions." Zhang Xiaolei, head of Standard Chartered Bank, said.

　　Schroeder Fund was recently approved to set up a wholly foreign-owned Public Offering of Fund management company in China, becoming the fifth wholly foreign-owned Public Offering of Fund company in China. Guo Wei, the person in charge of Schroeder’s investment, said: "This cannot be separated from the support of a series of favorable policies of the China government to expand the opening up of the financial industry. We will actively promote the preparatory work. "

　　According to the latest annual questionnaire survey of the German Chamber of Commerce in China, half of the enterprises surveyed expressed their willingness to continue to invest in the China market, and nearly 80% of the enterprises surveyed held a positive attitude towards the medium and long-term prospects of the China market, hoping to gain opportunities in the tide of scientific and technological innovation in China.

　　"From the extensive growth of scale and speed to the intensive growth of quality and efficiency, and from the drive of factor investment to the drive of innovation, the continuous reform in China will help achieve high-quality development." Kang Zhongzhi, an economist of the International Monetary Fund, said in an interview with this reporter that in recent years, China’s capital market has been more deeply integrated into the global financial market system, and the negative list of foreign investment access has been reduced for several consecutive years. At the same time, China has given full play to the decisive role of the market in resource allocation, continuously strengthened the protection of intellectual property rights and deepened the reform of the household registration system, which has enhanced the vitality of market competition and the mobility of labor. China has achieved tangible results in promoting structural reforms on the supply side, and the economy will further achieve high-quality development in the future.

　　On January 8th, China resumed China citizens’ outbound tourism in an orderly manner, and gradually resumed the entry and exit of passengers at land and waterway ports. A number of foreign countries in the Chinese Chamber of Commerce recently said that this move has brought obvious benefits to the regional economy and global trade. The British Chamber of Commerce in China issued a statement saying that as the epidemic prevention and control entered a new stage, the optimism of enterprises continued to rise, and "China has once again become a priority investment destination".

　　The report released by the African Development Bank in January believed that after China optimized and adjusted its epidemic prevention policy, Asia, as an important export market in Africa, would achieve steady growth, thus expanding the development space of Africa.

　　Park Zhi-shui, chief economist of the Asian Development Bank, said that China’s economic recovery will greatly promote the Asian economy. The sharp rebound in consumer demand in China not only boosted the exports of trading partners to China, but also benefited all value chains connected with China.

　　Goldman Sachs Group recently released a report saying that the accelerated recovery of China’s economy will boost global economic growth. "With the improvement of global financial conditions and the increase of international trade, the spillover effect of China’s economic growth will be even greater".

At present, the weather is getting colder and the temperature difference between day and night is large, which is in the high incidence season of influenza.

Huang Li, deputy director of the Institute of Infectious Disease Prevention and Control of the State Center for Disease Control and Prevention, and Li Fuqiang, an expert on planned immunization, warmly reminded that to prevent seasonal high-incidence respiratory infectious diseases such as influenza, we should make preparations in advance, raise awareness of disease prevention and strengthen health protection.

What is the flu?

Influenza (hereinafter referred to as "influenza") is an acute respiratory infectious disease caused by influenza virus, which is harmful to human health. It can be divided into four types: A, B, C and D. Seasonal influenza viruses include subtype A H3N2, subtype A H1N1 (pdm09), strain B Victoria and strain B Yamagata.

According to Huang Li, the flu mainly manifests as fever, headache, general malaise and other symptoms, and the body temperature can reach 39~40 degrees Celsius. Children’s fever is usually higher than that of adults, and the symptoms may include chills, chills, aching muscles and joints all over the body, fatigue, accompanied by loss of appetite, etc., as well as sore throat, cough, nasal congestion, runny nose, retrosternal discomfort, facial flushing, conjunctival congestion and so on.

Influenza is mainly spread by droplets such as sneezing and coughing. Influenza virus survives in the air for about half an hour. It can be infected by direct or indirect contact with oral cavity, nasal cavity, eyes and other mucous membranes, and it can also be infected by touching articles infected by the virus. In crowded, closed and poorly ventilated places, influenza may also spread in the form of aerosol.

People are generally susceptible to influenza virus, and most of them are self-limited. Some patients will have complications, which can develop to severe illness or even death. The elderly over 65 years old, children under 5 years old, especially children under 2 years old, pregnant women and patients with basic diseases are high-risk groups of influenza and need special attention.

Huang Li reminded that maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. For example, wash your hands frequently, keep indoor ventilation, try to avoid going to crowded places, have a balanced diet, exercise, and minimize rubbing your eyes, nose and mouth when you are in public places. You should also pay attention to regular work and rest, balanced nutrition, avoid overwork, and maintain your immunity. It is best to wear a mask when you go to a medical institution for medical treatment.

"In addition, the most effective means to prevent influenza is to inject influenza vaccine, especially for key populations. Annual influenza vaccination can significantly reduce the risk of influenza and serious complications." Huang Li said.

It is recommended to vaccinate against influenza in time.

According to Li Fuqiang, according to the Technical Guide for Vaccination of Influenza Vaccine in China (2023-2024) recently issued by the China Center for Disease Control and Prevention, annual vaccination with influenza vaccine is an effective means to prevent influenza, which can effectively reduce the risk of influenza and serious complications among the vaccinators. Suggest ≥ People who are 6 months old and have no vaccination contraindications should be vaccinated against influenza, especially the following key groups are recommended to give priority to vaccination:

1 medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.;

2. Participants and security personnel in large-scale activities;

3. Vulnerable people and employees in old-age care institutions, long-term care institutions, welfare homes and other crowd gathering places;

4. People in key places, such as kindergartens, teachers and students in primary and secondary schools, and detainees and staff in prison institutions;

Family members and caregivers of infants under 5.6 months old and pregnant women;

6. Other people at high risk of influenza, including elderly people aged 60 and above, children aged 6 months to 5 years, and patients with chronic diseases.

Usually, antibodies with protective level can be produced after 2~4 weeks of influenza vaccination, and it is best to complete the vaccination before the peak of influenza epidemic in autumn and winter. In the same influenza epidemic season, people who have completed the whole vaccination according to the vaccination procedures do not need to be vaccinated again.

Li Fuqiang introduced that influenza vaccine is a non-immunization program vaccine, and residents can be informed, voluntary and self-funded. At present, influenza vaccines used in China are mainly divided into two categories: inactivated influenza virus vaccine and live attenuated influenza virus vaccine. The influenza vaccines approved for marketing in China include trivalent inactivated vaccine (IIV3), trivalent inactivated vaccine (LAIV3) and tetravalent inactivated vaccine (IIV4), all of which can effectively prevent influenza virus infection. Residents can choose one influenza vaccine by themselves. At present, there are sufficient reserves of influenza vaccine in vaccination clinics all over the state.

Because influenza virus is easy to mutate, it is necessary to get flu vaccine every year. Like many other vaccines, influenza vaccination does not necessarily mean that you will not get the flu, but it can alleviate the symptoms after getting the flu, significantly reduce the risk of developing into a serious illness, and avoid developing into a serious illness and death.

Experts from the State Center for Disease Control and Prevention reminded that residents who care for their health can get the flu vaccine as soon as possible, especially those who have children, pregnant women, the elderly and other key personnel at home, and should take the initiative to vaccinate the whole family as soon as possible to build a family immune barrier to protect themselves and their families from the flu. You can go to the nearest community health service center (community health service station), the vaccination clinic of township hospitals and the health department of the hospital for vaccination. You can also make an online appointment through WeChat WeChat official account of Hubei Provincial Center for Disease Control and Prevention, and make an appointment in advance for the vaccination clinic and vaccination time, which is more time-saving and convenient.

How do students and parents take precautions?

The flu is coming, how can students and parents prevent it? Huang Li suggested that personal protection is the most important, and ventilation and disinfection should not be forgotten.

Students and parents need to do personal protection, wear masks, wash their hands frequently, pay attention to cough etiquette, try to avoid going to crowded places and avoid close contact with people with respiratory symptoms. If family members have respiratory symptoms, they should rest at home, observe their health, go to work and attend classes without illness, and wear masks when they are in close contact.

Children’s three meals a day need balanced nutrition, appropriately increase high-quality protein such as meat, eggs and milk, and eat more fruits rich in vitamin C. Ensure the length of children’s sleep, and adequate sleep has a positive impact on enhancing physical fitness. Primary school students should sleep 10 hours a day, junior high school students 9 hours and senior high school students 8 hours.

Always ventilate your home and keep the environment clean. Open the window for ventilation 2~3 times a day, with no less than 30 minutes each time. If it is inconvenient to open the window for ventilation, mechanical ventilation can be carried out with the help of an exhaust fan. After patients appear in the family, the surfaces of environmental objects contacted by patients can be disinfected with chlorine-containing disinfectant containing 250 mg/liter of available chlorine, or wiped with disinfectant wipes, and the surfaces of small items can be wiped with 75% alcohol.

Huang Li stressed that in addition, students and parents should be vaccinated as soon as possible. For high-risk groups such as young children who have not been vaccinated with influenza, vaccination as soon as the influenza vaccine is available can play a good preventive and protective role.

How do schools and kindergartens prevent it?

Li Fuqiang suggested that schools and kindergartens should do a good job in health monitoring, strengthen ventilation and disinfection, and build a strong immune defense line during the high-incidence season of influenza.

Schools and kindergartens should strengthen morning and afternoon inspections and full-day observation. Strengthen the registration system of absence due to illness, grasp the reasons of students’ absence, and find and report early. When influenza cases occur, patients should be allowed to rest at home to reduce the spread of the disease.

Schools should take advantage of students’ recess, physical education class, after school and other periods to strengthen classroom ventilation, so as to keep the classroom air circulating and fresh. Every morning, noon and evening, windows should be opened for ventilation, and the ventilation time should not be less than 30 minutes each time. Every day after school, the key places in the classroom should be cleaned and disinfected regularly. Nursery institutions should clean and disinfect students’ toys and other items every day.

Schools should publicize influenza prevention knowledge to teachers and students through radio, LED screens, blackboard newspapers, billboards, leaflets and lectures, do a good job in health education, help teachers and students develop good personal habits such as washing hands frequently, wearing masks and coughing etiquette, and improve their self-prevention ability. In addition, during the epidemic of respiratory infectious diseases such as influenza, schools should try to reduce or avoid large-scale gatherings and other collective activities to reduce the risk of transmission.

As a means of transportation that relies on electric energy, it is essential to charge electric vehicles. However, different car owners have different ideas about the habit of charging electric vehicles. Some of them charge only when the power is running out, and some people charge frequently and charge every day. So, can electric vehicles be charged every day? The little expert made it clear once today and really learned it after reading it.

As for the way of "charging every day", it can’t be said that it is absolutely correct or absolutely wrong. After all, if the battery life of an electric car is only forty or fifty kilometers and you travel twenty or thirty kilometers every day, you have to charge it every day. Whether you can charge it every day depends on whether the advantages outweigh the disadvantages or the disadvantages outweigh the advantages. Let’s take a detailed look at the advantages and disadvantages of "charging every day" of an electric car.

Regarding the habit of "charging every day", what are the advantages of it compared with the need to use clean electricity to recharge? According to the expert’s summary, there are two simple and clear ones.

The first is to reduce the battery vulcanization reaction and slow down the battery aging speed:

What kind of battery is the fastest aging, that is, the battery with faster vulcanization speed, which leads to battery vulcanization, and the most important point is power loss. As long as the battery is discharged and not replenished in time, the sulfuric acid concentration of the battery is thin, and sulfide crystals will form, which will lead to battery capacity reduction and battery aging.

If the battery is charged every day, it can be replenished in time after discharge, and the concentration of electrolyte in the battery gradually increases, returning to the concentration before discharge, which can prevent the battery from vulcanizing and slow down the aging speed of the battery.

Secondly, there is no need to worry about the power failure halfway, and there is no need to take emergency treatment methods that damage the battery:

If the electric car is charged every day, there will naturally be no trouble in the middle of the road. As long as there is no electricity in the middle of the road, the emergency switch such as ACS provided by the manufacturer will not be used by the owner, and there is no need to worry about damaging the battery.

As for the ACS switch, it can still release electric energy when the electric vehicle shows insufficient power, but once it is turned on, it will release all the protection voltage of the battery, which is very harmful to the battery. If it can be used, try not to use it.

Talking about the advantages of charging every day, but since discussing this way, there must be advantages and disadvantages, otherwise there is no need to discuss it. Then, what are its disadvantages, you can also sum up two.

The first is the waste of cycle charge and discharge times of the battery:

No matter what kind of battery, as long as the cycle charge and discharge times are used up, the battery will be scrapped, and charging every day with enough electricity will inevitably lead to the waste of times, especially lead-acid batteries, which must be avoided. It only has about 300 charge and discharge times. If it is used once every three days, it can be used for three years. If it is charged every day, the usable time of the battery will inevitably be shortened.

Secondly, it is easy to accelerate the water loss rate of the battery;

There are two important structures in the battery, the first is the lead plate, and the second is the electrolyte. If the battery is charged every day, the battery temperature will inevitably rise, which will evaporate the electrolyte. If a battery is charged and charged infrequently every day, the water loss rates of the two will be obviously different. When the battery electrolyte is insufficient, the battery performance will be affected and its life will be shortened.

Through the above introduction, we can get an answer. It is not recommended to "charge every day" for electric vehicles. Of course, if the power of electric vehicles is not enough to maintain the battery life for 2 days, it can be "charged every day". Compared with daily charging, it is not perfect. The following experts share the correct charging method, which is conducive to improving battery life.

1. The power of the electric car is enough for more than 2 days. Don’t charge it every day. Recharge it when the power is about 20%.

2, equipped with a lithium battery, because the number of charge and discharge is more than 1000 times, you can charge according to your habits;

3. Charge electric vehicles to avoid sub-zero environment;

4. Every time the electric car is charged, the charger will continue to charge after it turns green to complete the floating charge;

There is no need to choose between the charging habits of electric vehicles. Whether electric vehicles should be charged every day depends on the battery capacity and battery type. Can electric vehicles be charged every day? Through the analysis, it can be seen that lithium batteries are completely ok, while lead-acid batteries have advantages and disadvantages. It is necessary to master the correct charging method according to the situation of electric vehicles and improve the battery durability. What do you think of this? Welcome to comment and exchange.
