Xinhua News Agency, Shanghai, April 22nd Question: High-end car sales are exposed again "hidden rules": Is it compliant to increase the price by several hundred thousand yuan in addition to the price tag?

　　Xinhua News Agency "Xinhua Viewpoint" reporters Zhao Yihe, Lu Wenjun and Wang Chenyang

　　If the vehicle is clearly marked with a price of more than 770,000 yuan, an additional price increase of 300,000 yuan is required to pick it up, and you can’t buy a car without the price increase … … "Xinhua Viewpoint" reporter recently visited a number of automobile 4S stores and found that the price increase of some high-end models has become a "hidden rule" in the market. Is the price increase sales compliant and legal? Whose pocket did the extra money go into?

　　Mr. Wu of Shanghai recently bought two top-selling Toyota cars. In addition to the price of more than 770,000 yuan, he increased the price of each car by about 180,000 yuan. "The price increase of high-end hot-selling cars is the market ‘ Unspoken rules ’ 。” Mr. Wu said.

　　Mr. Tian from Luoyang, Henan Province, recently had a similar experience. "I bought a Japanese LX570(5-seat version) car with an original price of 1.417 million yuan and a price increase of 300,000 yuan. After going to several dealers, you need to increase the price. If you don’t increase the price, you can’t get the car. " Mr. Tian said.

　　The reporter visited several dealers in Shanghai on the spot and consulted the quotation of a hot-selling car of Toyota. A seller in Minhang District provided a quotation to the reporter. The column of "car price" on the quotation showed that the price was 774,000 yuan, and the column of "price increase" marked "208,000 yuan". On the quotation given by another dealer, the column of "original car price" says "77.4", and the car price after discount says "77.4+28.5". The salesperson said that 285,000 yuan is a fare increase.

　　The reporter also consulted several other dealers, and the price increase of this model ranged from 250 thousand yuan to 350 thousand yuan. The reporter asked a salesperson of a Toyota store in Minhang District, Shanghai if he could wait a little longer without increasing the price. The salesperson said that "all of them have to increase the price".

　　The reporter’s investigation found that at present, it has become a "hidden rule" for some high-end models to raise the price in addition to the clearly marked price. For example, in some areas, a high-end off-road vehicle of Mercedes-Benz needs to increase the price by about 500,000 yuan.

　　The new automobile sales management measures implemented in July 2017 stipulate that dealers should clearly state the price of selling automobiles, accessories and other related products and the charging standards for various services in an appropriate form at the business site, and may not increase the price or charge extra fees beyond the marked price.

　　According to industry insiders, in fact, dealers also know that price increase is an improper act. Therefore, when selling cars, most of them will not let the word "price increase" clearly appear in relevant sales agreements and bills.

　　The reporter’s investigation found that some dealers increase their prices without issuing invoices to consumers. Mr. Henan Tian said: "I paid a total of more than 1.7 million yuan in two times, but I only got an invoice of 1.417 million yuan. I don’t want to invoice the money that was increased." Mr. Dong, who bought a Japanese LX570 car in Henan, also confirmed to the reporter that the car was paid, but the dealer only invoiced the price of the car, and the price increase was not shown on the invoice.

　　Some dealers said that if the fare increase part needs an invoice, they need to pay additional tax points. A Toyota salesperson in Minhang District, Shanghai told the reporter that if the fare increase part is invoiced, it needs to bear 13% of the tax point. The reporter counted the quotations of many dealers and found that the tax points increased ranged from 13% to 17%. Part of the invoice for the fare increase can be issued on the car price, which means that consumers have to pay more purchase tax. If the price increase part is invoiced separately, only service fees, decoration fees, maintenance fees and accessories can be invoiced.

　　Whose pocket did the fare increase go into? A number of salespeople told reporters that this part of the income mainly went into the pockets of dealers. A variety of models sold at a higher price are "tight goods" in the market. After dealers get the goods, they will naturally raise the prices.

　　Jia Xinguang, executive director of china automobile dealers association, said that automobile dealers have formed a price alliance to some extent, and consumers are in a weak position when buying cars, which is one of the reasons for the phenomenon of dealers increasing their prices.

　　Because most of the dealers’ price increases are high-end cars, some voices on the Internet believe that the price increase of high-end cars is purely "one is willing to fight and one is willing to suffer". In this regard, industry experts believe that, in fact, this kind of price increase behavior infringes on the legitimate rights and interests of consumers and must be taken seriously, otherwise it will eventually hurt all consumers. Liu Chunquan, a lawyer of Shanghai Duanhe Duan Law Firm, said that according to the Consumer Protection Law, consumers have the right to fair trade. Dealers charge after the retail price is announced, which infringes on consumers’ right to fair trade.

　　The person in charge of the automobile office of the Shanghai Consumer Protection Committee said that the price increase without express indication and the consumers could not make a choice obviously infringed on the consumers’ right to choose independently.

　　According to the provisions of the automobile sales management measures, dealers are not allowed to increase sales or charge extra fees beyond the price tag. In violation of the provisions, the local competent commerce department at or above the county level shall order it to make corrections, and may give a warning or a fine of not more than 30,000 yuan.

　　Zhang Wenbin, a lawyer of Beijing Hairun Tianrui Law Firm, said that the warning and the fine of less than 30,000 yuan stipulated in the automobile sales management measures are relatively light compared with the price increase of several hundred thousand yuan, so it is difficult to really play a warning role. Dealers don’t make out invoices or open tax receipts of other names at will, which is suspected of tax evasion.

　　It is worth noting that in recent years, in several disputes between consumers and dealers caused by increasing the price of cars, the court supported consumers’ demands for rights protection. In 2016, Beijing Baideli Star Automobile Sales Company was sued by consumers for selling a high-end off-road vehicle of Mercedes-Benz at a price increase of 145,000 yuan. The Haidian District People’s Court of Beijing ruled in the first instance that Baideli Company returned 145,000 yuan to consumers. Subsequently, Baideli Star Automobile Sales Company refused to accept the appeal. In 2018, the Beijing No.1 Intermediate People’s Court rejected the appeal in the second instance and upheld the original judgment.

　　Industry insiders suggest that the relevant regulatory authorities should urge dealers to clearly mark the prices of vehicles and related services, and disclose the specific service items contained in them to prevent the behavior of "boring the package"; Support consumers to complain about price increase sales and defend their rights through legal channels. In addition, consumers should also resolutely say "no" to fare increases, not blindly follow the trend, rationally consume, and cut off the "black hand" of fare increases from the source.

　　Self-heating instant chafing dish becomes "online celebrity". Experts suggest to formulate corresponding standards and strengthen management.

　　You can eat a steaming hot pot with a glass of cold water without fire or electricity. Since the beginning of this year, "self-heating instant hot pot" with an average price around 35 yuan has mushroomed on various e-commerce platforms. Specific to the name, in addition to "self-heating instant hot pot", there are "portable pot", "micro hot pot", "light boiled hot pot" and "instant hot pot". What is a self-heating instant hot pot? Do you need a corresponding production license to produce this hot pot? How to ensure food safety? The reporter learned about the issues of public concern.

　　

　　Self-heating instant hot pot is popular now.

　　Low price, convenient use and monthly sales of more than 100,000 orders.

　　"An otaku is a must", "A must when traveling", "Spicy hot pot can be eaten if you want" and "4-8 people can have a party with friends and relatives just right" … Enter "self-heating convenient hot pot" on Taobao, and search for 1371 related stores and 20 brands. The manufacturers are mainly Sichuan and Chongqing, and the top seller is Chengdu catering hot pot brand. The price range of a single box is from 28 yuan to 38 yuan, and each box consists of a heating bag, a meat bag, a vegetarian bag, a wide flour bag and a butter bag. In an online store with high sales volume, the monthly sales exceed 100,000 orders.

　　According to a seller, self-heating instant hot pot means that you can enjoy steaming hot pot without fire or electricity, just with a cup of cold water. What is the principle of this? According to reports, the hot pot is divided into upper and lower layers. Before eating, you only need to put the ingredients with bottom materials into the upper layer, then put the heating bag composed of coke powder, activated carbon, salt and quicklime into the lower layer, and add cold water, which can immediately generate heat to heat the ingredients in the upper layer, so that the soup will boil and keep warm for 1 to 2 hours.

　　In addition to the hot online sales, there are also retail stores in many supermarkets. The reporter saw in a supermarket on Guanghua Avenue that the price of a brand of micro-hot pot was 35.8 yuan. A citizen who is choosing told the reporter that the self-heating instant hot pot is very convenient. After 15 minutes, you can eat it by pouring sesame oil. "It is simple, fast and has no smell of oily smoke. It is suitable for taking it on the road when traveling, and it tastes good!"

　　Favored by young people, the sales channel is mainly e-commerce

　　"Self-heating instant hot pot was produced in 2015, and it quickly became popular during the sugar and wine party this spring." Yuan Xiaoran, Secretary-General of Chengdu Catering Trade Association, introduced that it first rose in the circle of friends in Wechat business. As the self-heating technology is generally mature, more and more catering enterprises and food enterprises pay close attention to this field, and then gradually move towards e-commerce platforms and supermarkets such as Taobao and JD.COM.

　　At present, the consumer groups of convenient self-heating hot pot are mainly young people such as singles and office workers. Combined with young people’s consumption preferences, all manufacturers mainly use e-commerce channels. At present, well-known hot pot chains, including Dalongyi, Bashu Lazy, Xiaolongkan, Haidilao and Dezhuang, have "piled up" to launch various self-heating instant hot pot brand products. Most brands of instant hot pots can be bought on e-commerce platforms, and some can only be bought in physical stores or take-away platforms.

　　So, why is the self-heating instant hot pot so hot? The insiders believe that this "lazy hot pot" technology is relatively simple, easy to standardize and scale, and convenient for consumers to eat, so it suddenly became popular on social networks and quickly became a "online celebrity". In addition, according to the 2017 China Catering Report, every 10 yuan in China’s catering consumption comes from take-away. From the perspective of "lazy economy", the "decline" of instant noodles does not mean that the demand for instant noodles has decreased. As long as the products are iteratively upgraded in quality, they will naturally regain the favor of consumers.

　　"Follow the trend and trend. According to industry estimates, the convenient self-heating hot pot in the future will create an output value of 100 billion yuan a year. " The relevant person in charge of the Chengdu Food Chamber of Commerce said in an interview that the manufacturers of convenient self-heating hot pot in the market include hot pot catering enterprises, convenience food enterprises and condiment enterprises, among which there are nearly 100 "Made in Chengdu", and they are very optimistic about the prospect of convenient self-heating hot pot.

　　The industry is still in the initial stage, so it is necessary to ensure "safety and hygiene"

　　However, some insiders suggested that self-heating instant hot pot, as an innovative food category, is still in the initial stage. Due to the low threshold, most raw materials in actual production are assembled and produced in the form of OEM, and there is no industry standard to regulate it, resulting in the lack of standards for its production enterprises and self-heating hot pot products. A staff member in charge of food supervision of chenghua district Municipal Bureau of Market and Quality Supervision revealed that it is worrying that the self-heating instant chafing dish has not been included in the Catalogue of Food Production License. The reporter checked the 2016 edition of the Catalogue of Food Production Licenses issued by the State Food and Drug Administration and found that only fried instant noodles, instant rice, instant porridge, instant rice noodles, etc. were found in the catalogue of instant foods, and no self-heating instant hot pot was found in the whole catalogue. At the same time, reporters found on Taobao, JD.COM and other platforms that some buyers gave many bad reviews, such as "the meat in the hot pot bag stinks" and "a hair was found in the bag".

　　"As a category of innovative food, it basically showed a trend of barbaric growth when it first came out." Li Cheng, member of the Chengdu Food Safety Expert Committee and dean of the College of Food Science of Sichuan Agricultural University, told the reporter that hot pot is a special food in Chengdu and Chongqing, and it is necessary for relevant government departments to introduce relevant policies to ensure its healthy development while strengthening management.

　　Li Cheng suggested that the government should formulate a set of detailed rules on production, management and operation, and determine the standards, so that all self-heating instant chafing dish merchants can produce and operate according to the standards; At the same time, we should do more in-depth research, combine local characteristics, and try our best to ensure its characteristics; In addition, we must strictly implement the relevant food supervision regulations of the state, provinces and cities to ensure their safety, hygiene and reliability.

　　The reporter interviewed many hot pot merchants such as Huangcheng Mom and Xiaolongkan. Everyone agreed that self-heating hot pot, as an innovation and extension of hot pot food, is the crystallization of the wisdom of many hot pot merchants. Government departments should formulate relevant standards to protect and promote development and standardize the industry. "We will also proceed from ourselves and resolutely achieve food safety and hygiene." Kong Linglong, general manager of the administrative department of Huangcheng Mom, said.

　　"As far as I know, the relevant departments in Chengdu are formulating relevant regulations on the production license of self-heating instant hot pot." Lin He Yi, the media public relations officer of Xiaolongkan, told the reporter that it is expected that the introduction of the regulations will prevent unqualified manufacturers from disrupting the market, eliminate enterprises with poor quality and no food safety guarantee, and promote the healthy and orderly development of the whole hot pot industry.

　 　Obesity is like a fulcrum, which can easily "incite" a series of chronic diseases such as coronary heart disease, hypertension, hyperlipidemia and diabetes.

　 　 Most people think that obesity is eaten, so in order to lose weight, many people choose to go on a diet. As everyone knows, obesity may also be caused by spleen deficiency. Although dieting can reduce calorie intake, it will also reduce the body’s basal metabolic level. In the long run, the body will gradually enter the "low metabolism mode", and people will feel groggy all day long, lack energy, and even have many problems such as anorexia, malnutrition and endocrine disorders.

　 　 In fact, it is not so difficult for Chinese medicine to lose weight. To maintain a healthy weight, it can be achieved by "supplementing". Today, Yuan Zhenfang, chief physician of Endocrinology Department of Peking University First Hospital, Jing Lulu, nutritionist in charge of Clinical Nutrition Department of Peking University First Hospital, and Hu Jia, deputy director of Spleen and Stomach Department of Jiangxi Provincial Hospital of Traditional Chinese Medicine, will tell you why "being hungry and thin" is not as good as "making thin" and how to make up for it.

　 　 Your obesity may be due to spleen deficiency.

　 　 Spleen is a transit station in the body, and its function is to transport water and fluid in the body. After the human body ingests food, it needs to rely on the spleen to transform the food into nutrients and transport them to all parts of the body, and at the same time remove the phlegm and other garbage.

　 　 As the saying goes, "ten fat people have nine deficiency", and the "deficiency" here refers to spleen deficiency. Once spleen deficiency and body fluid flow have an impact, a lot of moisture accumulates in the spleen and stomach, which will lead to excess heat in the body, which will be converted into fat and phlegm, which can not be discharged normally, and people will become fatter and fatter.

　 　 In addition, people with spleen deficiency are generally cold, and they prefer to eat greasy and heavy-flavored foods to keep themselves warm, but this will aggravate the humidity and increase the possibility of obesity. This has led to a vicious circle of spleen deficiency, people getting fatter, and people getting fatter and spleen deficiency.

　 　 Spleen deficiency can make people fat, so what causes spleen deficiency to get fat?

　 　 There are too many bad emotions. In modern society, everyone has to face many things, the pressure is increasing, and there are more and more negative emotions. When the negative emotions increase, people will become lazy, so it is difficult to consume the heat in the body, and the burden on the spleen will become heavier, which will lead to spleen deficiency and obesity.

　 　 The diet is unreasonable. There is also a great relationship between the daily diet and the weakness of the spleen and stomach. If the diet is right, the digestion and absorption of the spleen and stomach will be good. If you don’t pay attention to diet, overeat and eat a lot of cold food on weekdays, it will bring a burden to the spleen and lead to damage to the spleen.

　 　 There is something wrong with the stomach itself. The food we eat needs the interaction of spleen and stomach in order to be better digested and absorbed. If there are problems in the stomach and intestines, the food digestion speed will slow down, the burden on the spleen will also become heavier, and obesity due to spleen deficiency will not be far off.

　 　 Losing weight "hungry" is not as good as "making up"

　 　 Compared with "hunger and thinness", Chinese medicine advocates "supplementing thinness", that is, balancing functions by strengthening the spleen:

　 　 Reinforcing thinness focuses on nourishing spleen.

　 　 Spleen is afraid of irregular life, and the easiest way to replenish spleen is to develop a good habit: eat three meals on time and in quantity, drink water when not thirsty, defecate regularly, avoid overeating, and limit alcohol and tobacco; Don’t eat after 9 o’clock in the evening. At night, the work efficiency of the spleen and stomach is low, and supper is easy to accumulate in the body and become excess heat.

　 　 Traditional Chinese medicines such as hawthorn, salvia miltiorrhiza, lotus leaf, medicated leaven and cassia seed have the effects of invigorating spleen and reducing fat, and can be made into dietotherapy or single tea. In addition, you can choose Chinese medicine for cooking porridge.

　 　 Glutinous rice yam porridge: wash glutinous rice, cook porridge with slow fire, add small pieces of yam when it is ripe, and continue cooking for 15 minutes before taking it.

　 　 Chinese yam and lotus seed millet porridge: peel and dice Chinese yam, remove the core of lotus seed, add millet, boil in a casserole with strong fire, and simmer slowly to make porridge.

　 　 Exercise can make you thinner.

　 　 Exercise is an effective means to consume calories and build up the body, which can promote gastrointestinal peristalsis, speed up metabolism, replenish spleen with vitality and remove turbid qi, and is the best tonic for the obese.

　 　 It is advisable to choose low-intensity and persistent sports, such as Tai Chi, Baduanjin, skipping, jogging, ball games, swimming and square dance, and the exercise intensity should be gradual. The best exercise time is recommended to be 1-1.5 hours after meals, which can not only strengthen the body, but also consume calories.

　 　 Acupoint to push abdomen and make thin.

　 　 Taibai point, Sanyinjiao point, Yinlingquan point and vein point of Zushaoyang gallbladder meridian on the spleen meridian are commonly used for slimming. Pressing them or moxibustion with moxa sticks can promote the return of qi and blood in the lower limbs, which is beneficial to strengthening the temper.

　 　 Pushing the abdomen can make 12 meridians unblocked and take away the "garbage" of the body. The specific method is: first push from the heart socket with the index finger belly. Sometimes you may feel bored in your heart. At this time, you should push this gas away. When you push it, you should push it down and push it through the belly button to the small abdomen. After pushing the middle, push both sides, and when pushing the liver meridian (flank), push it obliquely to the middle.

　 　 Push it once before going to bed, and push it again before getting up the next day for 5 minutes each.

　 　 What criteria are met to be fat?

　 　 Many people are not satisfied with their figure, but whether they are fat or not is not only judged by "looking". Only those who meet the following four standards need to lose weight.

　 　 ◎ Look at the body mass index

　 　 Body mass index (BMI)= weight (kg)/height (m) squared. According to Chinese standards, BMI is between 18.5 and 24, which is normal weight; More than 24 is overweight, and more than 28 is obese.

　 　 Look at the waistline

　 　 To measure the waist circumference, stand with your feet 30cm apart. The measuring part should be flat on the umbilicus. Use a soft ruler to cling to the skin, but do not press it. Adult male waist circumference should be less than 85cm, and female waist circumference should be less than 80cm.

　 　 ◎ See waist-hip ratio.

　 　 Stand upright, inhale gently, and measure the waist circumference above the navel and the most protruding hip circumference with a tape measure. WHO suggests that if the waist-hip ratio is greater than 0.9 for men and 0.85 for women, it is necessary to manage the weight in time.

　 　 ◎ Look at the thickness of subcutaneous fat

　 　 The subcutaneous fat thickness of abdominal wall should be less than 15mm for men and not more than 20mm for women. This usually requires a professional sebum thickness gauge to measure.

　 　 The following groups of people are more likely to gain weight and need to focus on their own health: sedentary people; People under great pressure; People who eat too fast; People who lack sleep for a long time; People with irregular diets; People who often hunch over.

　 　 People who do five things are in better shape.

　 　 Obesity is a preventable disease, and some lifestyle changes contribute to weight management. In addition to the three methods of "slimming", you can also try the following tips to reduce weight.

　 　 Do it before you get fat

　 　 Systematic intervention and management must be carried out when the weight enters the "overweight" range, and we can’t wait until we reach the "obesity" level to pay attention to it. "Early intervention" is not difficult. First of all, put a weighing scale at home, measure it every day, pay attention to weight changes, and start to intervene once you find that you are overweight.

　 　 Be careful when eating.

　 　 Eat less red meat with high fat content such as pigs, cattle and sheep, and some can be replaced by white meat such as chicken and fish. When cooking oil, you should eat less saturated fat, such as lard, butter, butter and so on. Soybean oil, corn oil, sunflower oil and wheat germ oil can be used. Replacing part of polished rice flour with beans and potatoes and adding some miscellaneous beans to the staple food can reduce calories without reducing satiety. At the same time, we should pay attention to ensure the intake of necessary nutrients such as sugar, protein, vitamins and minerals.

　 　 Move every week

　 　 Exercise three times a week for at least 30 minutes each time helps to maintain a reasonable weight. Generally speaking, skipping rope and swimming consume more calories at the same time, followed by basketball, football and badminton, and cycling, running and walking are less. You can also integrate sports into your life, for example, take more steps on your way to and from work and do more outdoor sports on weekends. When heavier people exercise, they should pay special attention to protecting their knees. People who used to do little exercise can start from walking 3000-5000 steps every day and gradually cultivate exercise habits.

　 　 Have a good sleep at night

　 　 American studies have found that women who sleep only five hours a day are more likely to gain weight, and their chances of getting fat are 1/3 higher than those who sleep seven hours a day. Staying up late for a long time will affect endocrine, which will lead to increased risk of obesity and diabetes over time. When staying up late, you may eat "midnight snack" because of hunger, which is more likely to cause obesity.

　 　 Tired, hold on.

　 　 Everyone has inertia, which is a stumbling block on the road to weight reduction and control. It is suggested to find partners and friends to exercise together and supervise each other, which is more conducive to persistence. In addition, we should keep a normal mind, relax, don’t put too much pressure on losing weight, keep an optimistic and positive attitude, and prevent emotional overeating.

　 　 It should be reminded that weight loss needs to be done step by step. The WHO’s suggestion is to lose 0.5-1kg a week and 1-3kg a month. This "uniform" weight loss method has little damage to the body and is not easy to rebound.

　 　 For those who still can’t lose weight effectively through exercise and diet control for more than half a year, it is suggested to consult a doctor and take medication according to the doctor’s advice.

Lack of diagnostic gold standard, children need to be vigilant when they have fever!

In the past month, six children with Kawasaki disease were treated in the pediatric department of a hospital in Xi ‘an, four of them were in serious condition, and one child also developed Kawasaki disease shock syndrome. What exactly is this disease? What’s the performance? Many parents said that they have never heard of it and have never seen it.

Let’s get to know Kawasaki disease through a case.

A boy, 1 year old and 5 months old, was admitted to the hospital because of "fever for 6 days".

Six days ago, the child had no obvious cause of fever, with a heat peak of 39.7℃, accompanied by runny nose, nasal obstruction, cough, shortness of breath, wheezing, convulsions, vomiting and diarrhea. Fever did not improve after 4 days of oral administration of cefaclor dry suspension in outpatient department.

Physical examination: conscious, ruddy complexion, palpable swollen lymph nodes on both sides of the neck, about 2cm*1cm in size, no tenderness, no redness and swelling, but movable, scattered red rash on the trunk skin, fading after pressure, conjunctival congestion, no purulent secretion, dry red lips, no chapped lips, red bayberry tongue, pharyngeal congestion, swollen tonsils on both sides, no purulent secretion. Flushing and swelling can be seen in the palm and sole, and no peeling is found at the toe end. Scar without redness, perianal flushing, peeling.

Diagnosis: Kawasaki disease.

What is Kawasaki disease?

Kawasaki disease, also known as cutaneous mucosal lymph node syndrome, can’t be prevented, and the cause is still unclear. It is generally believed that Kawasaki disease is an acute systemic immune vasculitis triggered by infectious factors, with fever, jealousy, lip redness, rash and cervical lymph node enlargement as the main clinical manifestations. Cardiovascular injury, especially coronary artery disease, is an important complication of Kawasaki disease, which can lead to myocardial ischemia, myocardial infarction and even death, seriously endangering the health and life of children. Kawasaki disease mainly occurs in children under 5 years old, and can occur all year round, especially in East Asia such as China and Japan. The data published in recent years show that there are more than 100 new cases of Kawasaki disease per 100,000 children aged 0-4 every year.

What are the manifestations of Kawasaki disease?

Main clinical manifestations

1. Fever: It is often repeated fever, and the heat peak can reach 39-40℃, and antibiotic treatment is ineffective.

2. Changes of extremities: In the acute stage, the palms and soles flush and hard edema appear. At 2-3 weeks, desquamation (membranous desquamation) of fingers and toes starts from the nail week and can extend to the palms and soles of feet. The course of the disease lasts for 1-2 months, and deep transverse groove (Beau’s line) or nail removal may appear on the nail.

Fig. 2 membranous desquamation of hands and feet (from UpToDate)

3. Rash or redness at the BCG vaccination site: Rash usually appears within 5 days after fever, and there are common diffuse maculopapular rash, scarlet fever-like rash and erythema multiforme-like rash. Rash is usually widely distributed, mainly involving trunk and limbs. The aggravation of rash in groin and early desquamation, perianal flushing and desquamation are the characteristics of Kawasaki disease. Scar swelling is a relatively specific early manifestation of Kawasaki disease.

Fig. 4 Scar is red and swollen (I shot it myself).

4. Bilateral bulbar conjunctival congestion: Children may have bilateral bulbar conjunctival non-exudative congestion shortly after fever.

Figure 7 strawberry tongue (from UpToDate)

6. Non-suppurative enlargement of cervical lymph nodes: usually unilateral, with a diameter ≥1.5cm.

Auxiliary inspection

1. Laboratory inspection:

① Blood routine showed an increase in white blood cell count, mainly neutrophils; Decreased hemoglobin; The increase of platelet count usually appears in the second week of the course of disease, reaches its peak in the third week, and returns to normal in 4-6 weeks; A small number of children can have a decrease in platelet count, which indicates that the condition is serious.

② Urine routine showed leukocytosis, but urine culture was negative.

③C-reactive protein and serum amyloid A(SAA) increased, and erythrocyte sedimentation rate (ESR) increased.

④ Transaminase increased, total bilirubin increased, creatine muscle enzyme and myocardial isoenzyme increased, albumin and blood sodium decreased.

⑤ Serum inflammatory factors such as interleukin (IL)-6, IL-1 and tumor necrosis factor α (TNF α) are increased.

⑥ Plasma brain natriuretic peptide (BNP) or N-terminal pro-brain natriuretic peptide (NT?proBNP) increased, procalcitonin increased slightly and moderately, and serum ferritin and plasma dimer increased.

2. Echocardiography: Echocardiography should be performed as early as possible in the clinical diagnosis of Kawasaki disease to find out whether there is coronary artery damage, such as coronary artery dilatation or coronary artery aneurysm formation, and whether there is thrombosis should be paid attention to.

How to diagnose Kawasaki disease?

Kawasaki disease is a clinical syndrome, the diagnosis mainly depends on clinical manifestations, combined with laboratory examination and exclusion of other diseases. Kawasaki disease includes complete Kawasaki disease (CKD) and incomplete Kawasaki disease (IKD).

1.CKD: fever with at least 4 main clinical features of the following 5 items:

(1) bilateral bulbar conjunctival congestion;

(2) Oral and oral changes: dry and red lips, strawberry tongue and diffuse congestion of oropharynx mucosa;

(3) Rash, including red and swollen scar;

(4) Changes of extremities: redness and swelling of hands and feet in acute stage, and desquamation around nails in recovery stage;

(5) Non-suppurative cervical lymphadenopathy.

2.IKD: Children with fever ≥5d but with less than 4 main clinical features are assessed as IKD according to the flow chart in Figure 7.

Fig. 8 Diagnostic flow chart of incomplete Kawasaki disease [1]

What conditions need to be considered for Kawasaki disease?

According to the 2017 American Heart Association guidelines, Kawasaki disease should be considered in the following situations:

(1) long-term fever and irritability of infants younger than 6 months;

② Infants have long-term fever and unexplained aseptic meningitis;

③ unexplained long-term fever or shock with negative blood culture in infants or children;

④ Infants or children have long-term fever and cervical lymphadenitis, and have no response to antibiotic treatment;

⑤ Infants or children have long-term fever, retropharyngeal or parapharyngeal cellulitis, and have no response to antibiotic treatment.

Kawasaki disease needs to be differentiated from which diseases.

1. Scarlet fever: Kawasaki disease can also have a scarlet fever-like rash, but the simple scarlet fever infection is mostly effective for antibiotic treatment. After antibiotic treatment, the symptoms are improved and the inflammatory index is obviously reduced.

2. Other virus infections (such as adenovirus, enterovirus): In virus-infected blood, the routine white blood cell count is not high or low, but lymphocytes are increased, C-reactive protein, SAA and ESR are often not significantly increased, and the virus antibody in blood can be significantly increased.

3. Septic shock syndrome caused by staphylococci and streptococcal toxins: It needs to be differentiated from Kawasaki disease shock syndrome, especially when antibiotic treatment is ineffective, closely observe the other five characteristic clinical manifestations of Kawasaki disease except fever, and conduct echocardiography in time.

4. Drug hypersensitivity such as Stevens Johnson syndrome: There is a history of using sensitive drugs, and the mucosal manifestations are usually more serious. Moreover, the ocular symptoms are not only conjunctival congestion, but also catarrhal, suppurative and pseudomembranous conjunctivitis, which can leave eye complications.

How to treat Kawasaki disease?

Although Kawasaki disease cannot be prevented, it can be treated. Once it is diagnosed, it should be treated as soon as possible:

① High-dose intravenous immunoglobulin (IVIG): 2g/kg, the infusion time is usually 10-12h, and the dosage of 1g/kg per day can be used for children with heavy weight (such as > 20kg) for two days.

② Anti-inflammatory effect of aspirin: 30-50mg/(kg d), taken orally for three times. If the diagnosis of Kawasaki disease is delayed for more than 10 days or even longer, it is still recommended to give the above treatment as long as there are clinical symptoms and/or inflammatory indicators are still abnormal; If the clinical symptoms have subsided, the inflammatory indicators have returned to normal, and echocardiography shows no coronary artery lesions, only subsequent antiplatelet therapy and follow-up can be given.

③ Anti-platelet effect of aspirin: After 48-72h, the inflammatory indexes (white blood cell count and C-reactive protein) returned to normal, and aspirin was reduced to 3-5mg/kg. For children with no coronary artery disease or mild coronary artery dilatation in acute phase but returning to normal within 30 days, aspirin will continue to be used for 2-3 months.

Difficulties in diagnosis and treatment of Kawasaki disease in children

1. Kawasaki disease mainly depends on the clinical features, combined with the manifestations of systemic multi-system vasculitis and laboratory examination for clinical diagnosis, which lacks the gold standard and needs to exclude other diseases. The diagnosis of CKD is usually not difficult, but for the diagnosis of IKD and severe Kawasaki disease, clinicians need to be highly vigilant, combine laboratory indicators with echocardiography to make a comprehensive judgment, and sometimes even need dynamic observation during the course of the disease to make a diagnosis.

2. The main clinical features of Kawasaki disease rarely appear at a single point in time, and some clinical features will fade within a few days, so it is necessary to ask the medical history and physical examination carefully. Kawasaki disease is a self-limited disease, and the fever can stop automatically. Clinicians may ignore the main clinical manifestations of Kawasaki disease because of the cessation of fever, thus delaying the diagnosis and failing to improve echocardiography in time to evaluate whether there is coronary artery damage.

3. Kawasaki disease is systemic vasculitis, with multiple system injuries. The first symptom can be some specific organ injuries, and sometimes it is misdiagnosed as other diseases, such as urinary tract infection, suppurative lymphadenitis or mumps, acute abdomen, hepatitis and arthritis.

Summary:

Simple fever in the early stage of Kawasaki disease may be mistaken for a cold. Parents should see a doctor again in time for children with repeated fever with rash, jealousy and red lips. For children with fever for more than 5 days and poor antibiotic treatment effect, clinicians should consider the possibility of Kawasaki disease, ask for medical history and physical examination in detail, dynamically follow up relevant auxiliary examinations, and improve echocardiography in time. Children treated with IVIG rarely die of Kawasaki disease, and most of them have a good prognosis. The long-term complications are mainly related to the degree of coronary artery involvement. Take medicine according to the doctor’s advice after discharge, follow up regularly for fever and review echocardiography to evaluate the heart involvement.

　　Reconstruction project of old residential area with red star row tail.

　　Go to the grass-roots level in the new year

　　A few days ago, the Municipal Party Committee and the Municipal Government issued the "Action Program for Adhering to the Essence of the" 3820 "Strategic Engineering Thought and Accelerating the Construction of a Modern International City", proposing to build a more complete social security system and continuously enhance the sense of gain and happiness of the broad masses. In recent years, the continuous renovation of old housing areas in our city has improved the housing conditions of citizens and has been widely praised by the people. Residents involved in relocation often come to the project site to pay attention to the construction progress.

　　Residents involved in relocation

　　Pay attention to the construction progress

　　Yesterday, the reporter came to the reconstruction project plot of Taijiang Hongxing Paiwei contiguous old housing area at the intersection of Liuyi Middle Road and Paiwei Road. This is the site of Lanyue Garden project, and dozens of high-rise residential buildings have sprung up.

　　Because of the new construction method, the site looks neat. Although the Spring Festival has just ended, some workers have entered the site for construction. Outside the gate of the project site, the old couple Lin Yibo and Wang Yim are counting the floors and asking the doorman, "Can we go in and have a look?" Although they were explicitly rejected, the two old people were not upset and still inquired about the progress of the project construction with the doorman.

　　Wang Yim smiled and told reporters: "Our original house in Hongxing New Village was only over 60 square meters. When we moved, we paid more than 200,000 yuan and chose a large house of 90 square meters. Now that the relocation house has been selected, I am looking forward to moving to the new house as soon as possible. "

　　The doorman told the reporter that, like the two old people, the residents involved in the relocation came to the project and paid attention to the construction progress almost every day. The whole project was built little by little in the observation of the residents involved in the relocation.

　　The reporter learned from the relevant departments that the project currently under construction in Lanyue Garden Area 1 has completed the capping of the main structure and the construction of the roof filling and frame layer, and the adjacent three areas are in the basement construction and the upper main body construction stage.

　　It is understood that the renovation project of the old residential area in the red star row is a comprehensive residential project integrating high-end commercial housing, resettlement commercial housing and commercial comprehensive construction. With the completion of the project and the relocation of personnel, the area will be upgraded from the original "miscellaneous, chaotic and old" state to a noble and livable residential area. All this is just a microcosm of Fuzhou’s acceleration in filling the shortcomings of people’s livelihood infrastructure.

　　The resettlement commercial housing model has been deeply rooted in people’s hearts.

　　The reporter learned from the Municipal Housing Management Bureau that in August 2017, the Municipal Party Committee and the Municipal Government decided to launch the "2018-2020" three-year old renovation campaign, involving 106 contiguous old housing projects with poor living conditions and chaotic surrounding environment. This is the largest renovation of old housing areas in Fuzhou in recent years.

　　Through the three-year old renovation, the contiguous old housing areas such as Hongqiang New Village in Gulou District and its surrounding areas, along Gule Road, Hongxing Paiwei in Taijiang District, South Park, Sancha Street and Guozhai in Cangshan District, and Yangxia and Puxia in Jin ‘an District have been renovated.

　　In order to effectively ensure the effective promotion of the renovation of old housing areas, during the renovation, the city has formed an overall arrangement and scheduling mechanism for the renovation of old housing areas in urban areas. Once the new projects are determined, the local government will make clear the specific time node of net land delivery, do a good job of signing and relocating all houses in advance, and complete the net land delivery work in time.

　　In the renovation of contiguous old housing areas, the key link is to do a good job in resettling the residents involved. In order to solve the problem of relocation and resettlement from the source, in recent years, Fuzhou has pioneered the resettlement-type commercial housing model in China, and ensured that the resettlement work is fair, open and just. From the end of 2017, all land requisition and relocation projects in the city will solve the resettlement problem according to this model. At present, the operation of resettlement commercial housing in Fuzhou has been on the right track, and the efficiency, high quality and identity of resettlement commercial housing have been deeply rooted in the hearts of the people.

　　The reporter learned that after the large-scale renovation of old housing areas in stages, Fuzhou has now started the precise renovation action. In 2019, Fuzhou started the accurate old renovation of scattered plots in urban areas, and comprehensively mapped out the old houses that are not within the scope of renovation of contiguous old houses and renovation and upgrading of old communities, are ordinary bungalows, C-class and D-class dangerous buildings, or have scattered plots that seriously affect the landscape, and implemented accurate renovation in batches according to factors such as the degree of housing danger, landscape renovation requirements, and residents’ willingness to renovate. In the past two years, a total of 223 precision transformation projects of sporadic plots have been implemented, benefiting more than 2,700 households.

In late September, 2020, a user of "Anti-pressure Back Pot" of Million Bar told a story in his post that his mother sold her house to raise money because she couldn’t afford the bride price, and her sister who went to high school was not distressed, but also excitedly told the landlord "Brother, our family has money" on WeChat. The post quickly formed a high popularity in the bar, and the screenshots in the article were widely spread in major platforms. Countless netizens were moved and called "broken defense".

This is Baidu Post Bar’s latest outing, and the Chinese Internet has once again seen the powerful cultural creation and communication power of this ancient behemoth in the online community.

But many years ago, the post bar didn’t need this kind of broken circle, it was the biggest circle itself. At that time, half of the online buzzwords came from post bars every year, and their monthly activities accounted for half of the total number of netizens. Time has passed, and the king of the PC era has gradually declined in the era of mobile Internet. The reason is the evolution of the environment and the limitations of the product itself, but more is the blind pursuit and evil thoughts of the product leaders.

Now, it’s old, can you still eat?

The pinnacle of grassroots culture

On December 3, 2003, Baidu Post Bar was officially launched. Some people said that it was inspired by Li Yanhong’s idea of "building an online interest exchange platform with search engines". Others said that when Jun Yu searched the logs, he found that many users were searching for the same keyword, so he conceived to aggregate these people into an interest community.

As soon as it went online, Post Bar became popular because of its simple interface, low speech threshold and unique product form. At that time, Baidu’s main business was search engine, but search only grabbed and presented the existing information on the Internet, but it could not create content itself. The appearance of Post Bar made Baidu have the ability to produce its own content, which made up for the lack of Internet content at that time, and its proportion in Baidu traffic quickly increased from 1% to 11% later.

In 2004, the player Li Yi became popular because of the phrase "I protect the ball like Henry", and was called "Li Yi the Great". Li Yi Bar, the largest bar in Baidu Post Bar named after him, was also established. Later, due to Li Yi’s flamboyant style, more and more black powder poured into Li Yi Bar, and a unique "connotation" culture was formed, that is, various PS pictures, jokes and pranks were used to express their views on social current affairs.

The real rise of Post Bar was in 2005, when the phenomenal talent show "Super Girl" exploded, and fans began to hold a group discussion in their idol bars after the show was broadcast. At that time, there was no Weibo, and fans who had nowhere to go poured into Post Bar, which formed a huge flow. At the beginning of 2005, the number of users of Post Bar exceeded 10 million, and at the end of the year it soared to 30 million, surpassing Sina to become the largest Chinese website in the world.

On June 21st, 2007, a conflict broke out between Li Yi Bar and Chris Lee Bar. A large number of users of Li Yi Bar rushed into Chris Lee Bar to brush posts crazily, which caused Chris Lee Bar to explode more than 2,000 pages of meaningless content, making it paralyzed for a time. In the end, Chris Lee Bar suspended posting, and several bar owners members of Li Yi Bar were withdrawn. This is the first "expedition" of "Diba" and the first explosion in the history of Post Bar.

In the next few years, Li Yiba organized several "expeditions", but unlike the first "fighting" in the circle, most of the later explosions were just. For example, in August 2007, Rainie Yang Bar was exploded because Rainie Yang was suspected of insulting China and Nanjing Massacre martyrs. In May, 2008, some dance troupe players insulted the victims of Wenchuan earthquake, and the dance troupe bar was exploded.

From 2004 to 2010, the post bar at this stage was at its peak, and a large number of netizens from grass roots gathered in different post bars with their interests, producing numerous high-quality posts and settling them down, hence the name "Louvre on the Chinese Internet".

At this time, the post bar is the representative of the grassroots culture of the Internet. In this highly decentralized community where everyone is equal without hierarchy, countless lonely souls have found a sense of belonging. Bar friends are highly creative and enthusiastic, and these online buzzwords, such as diaosi, baifumei, Xi Da Pu Ben, Pipi Shrimp Let’s Go and Ignorance, are all born out of post bar culture.

Li Yanhong once said in an interview: "We just want to do our own thing in a down-to-earth manner and build Baidu into a place that can bring a sense of belonging to netizens." At this time, the post bar was really done.

When the giant slowly falls

No one thought that the infinitely brilliant post bar in the PC era would be "dead" in the era of mobile Internet.

In 2009, "God of Products", Baidu Post Bar and Jun Yu, the father of Baidu Know, left Baidu. In 2010, when Google left China, Baidu quickly ate Google’s market share, and a year later, its market value surpassed Tencent to become the top Internet company in China. Baidu, which has fallen into unprecedented loneliness, urgently needs to tell a new growth story, so it internally puts forward a long-term strategic goal of reaching 100 billion revenue within ten years.

After this strategic goal was put forward, it was widely valued by high-level and investors, and the long-term goal was continuously subdivided into KPI and distributed to various departments. At that time, Post Bar was a typical "traffic, no revenue", coupled with the high server cost due to high user volume and high activity, Baidu hoped that Post Bar could bear more responsibility for growth, and even put forward the slogan "How can it become an independent business unit without revenue?" Everything was in line with KPI. Post bar has thus embarked on its decline.

In the fourth quarter of 2011, the new version of Post Bar was released for public beta, and the bar owners audit system was cancelled when it was originally added to Post Bar, and it became click attention; At the same time, the hierarchy and experience system are introduced, and users can increase their experience value by logging in, posting, replying and other operations, so as to improve the level of posting.

A series of revisions have greatly improved the number and activity of users. However, the product logic of Post Bar is very unique: unlike today’s content products that use subscription system and recommendation algorithm to achieve the effect of "thousands of people and thousands of faces", the post bar pages are sorted according to the latest reply time of posts. Different users enter the same post at the same time and see the same content, which makes the post bar very public, and some stalks are very easy to form explosive points, resulting in great influence and even out of the circle.

However, this model also causes crowding and competition among contents. When many users start posting meaningless posts and pictures for experience, the content quality of the post bar will also decline.

In 2012, with the popularity of mobile Internet, Post Bar officially started its "self-destructive commercialization" process. Baidu requires bar owners, who has no salary, to bear the KPI of user growth and activity, and not to be dismissed or airborne in bar owners; In September, it was officially launched to promote the Post Bar, namely, the advertisement of the headline, the advertisement of the topic list page and the advertisement of the electronic details page. However, the excessive force led to too many advertisements on the page, which further reduced the visibility of the page. Since then, the content quality of Post Bar has been declining, but the overall afterglow still exists. In 2012, the number of netizens in China was 564 million, and the monthly activity of Post Bar was 200 million, accounting for more than one third.

In 2015, Baidu found that the commercialization attempts in recent years did not change the loss situation of Post Bar, so it finally made the worst decision in the history of Post Bar and even Chinese Internet: sell it.

An insider of Baidu once said when recalling this period of history: "Then, some people began to focus on the authority of bar owners. At first, there was a fierce internal argument, saying that this thing could not be sold, but the final outcome was known to everyone. Anyway, there are many internal objections, but let’s take advantage of the word. "

In March 2015, the infamous Baidu partner system was launched. When a merchant becomes a partner of Post Bar, he can have all the rights of bar owners, such as deleting posts, monitoring public opinion and initiating activities in the bar.

Baidu chose the former between interests and morality, which also brought bad consequences to society and Post Bar itself. In January, 2016, the news that "Hemophilia Bar" was sold gradually spread. The original bar owners was removed, and the airborne bar owners paid for the right to operate. A place where patients gathered for warmth for nearly ten years became a victim of over-commercialization. Later, netizens found that many medical-related post bars were sold by Baidu. Coupled with the Wei Zexi incident that occurred in the same year, the public image of Baidu and Post Bar plummeted and has not recovered yet. The Baidu partner system was also cancelled after the incident.

A series of events in 2016 marked the decline of Baidu and Post Bar, and since then Post Bar has never recovered. Later, with the admission of the regulatory authorities, Post Bar strengthened its internal audit management. In 2019, Post Bar officially banned all posts before 2017 on the grounds of "data system upgrade", and some of them were unsealed after a period of time, but some early posts that had settled down were deleted.

In March 2015, an organization gave data: the user activity of Post Bar is 1.8 times that of Weibo, and the number of monthly users is 300 million, exceeding Twitter; By February 2019, its monthly activity was only 46.08 million. One year later, this figure became 37.43 million, ranking 101 on the APP list. Post Bar completely lost its former glory.

Does Baidu still have a choice?

The direct reason for the decline of Post Bar lies in its extremely failed commercialization, but the root cause of commercialization failure is not only the deviation of Baidu’s values, but also the limitations of Post Bar itself. To be precise, the product form of Post Bar determines that it must face many difficulties in the process of commercialization.

There are two types of social interaction, one based on "relationship" and the other based on "theme". The core of the former lies in the construction of interpersonal relationship, and WeChat and Momo are typical products. The core of the latter is to gather a group of people who are interested in this topic by relying on the "theme", so as to generate communication and form interpersonal relationships. Post Bar is the leader of this kind of products.

When the recommendation algorithm continues to push the highly homogeneous information flow named "thousands of people and thousands of faces", Post Bar is truly "interest-centered". Any niche hobby can find its own gathering place and partner in Post Bar, and most users in the bar have a certain understanding of the theme, so it is very easy for anyone to get informative feedback when speaking in the bar. This product mechanism makes Post Bar have extremely strong content creation ability and high activity, and at the same time, it also produces a culture of absolute equality and high decentralization.

However, although this cultural atmosphere is conducive to content production, it is not conducive to product commercialization. Because a high degree of equality and decentralization means scattered traffic, it is difficult for KOL and professional content creators to stand out from ordinary users and get a lot of attention. Weibo, bilibili, Xiaohongshu and other content communities have a group of "big V" who rely on their own content to attract fans, and finally turn it into cash and undertake the commercialization function of the community. Advertisers and brands can easily carry out marketing activities by relying on them.

However, in Post Bar, high-level users and bar managers do not have much higher traffic and trust value than ordinary users. Coupled with the unique sorting mechanism by response time, brands and advertisers can hardly find a "central node" that can directly reach a large number of target users or provide trust endorsement.

Even if a commercial promotion post is specially opened, it is difficult to attract traffic and heat, and it will soon be buried in the information flow. What’s more, there are a large number of knowledgeable users in the bar, and they can see at a glance whether the promoted products are good or not. It is not a problem to spray inferior products for hundreds of floors in minutes. All these make the commercialization of Post Bar extremely difficult.

But does Baidu really have no choice?

The difficulty in realizing the content community has always been a long-standing problem in the Internet field. The unique product mechanism and community atmosphere of Post Bar make it more difficult to commercialize than ordinary content products by several factors, but does Baidu have no other choice but to sell it? I’m afraid not.

First of all, the traffic of Post Bar itself is large enough, and the aggregation logic based on interest also makes many Post Bar have a very active second-hand trading market. Baidu may refer to the model of Aauto Quicker and salted fish to establish an official trading platform to draw as the income base; Or social interest itself has a lot of imagination. When major dating apps are racking their brains to match users with the same interests, Post Bar has long had a unique advantage in this respect.

Furthermore, even if Post Bar is really unprofitable, it is of great strategic significance to Baidu. If Post Bar is not dead, Baidu will have a traffic treasure on a par with Weibo and bilibili, which will have a great synergy with other businesses, at the very least, it will not create a "hundred number" that it can’t afford.

Selling it is the last choice, because in the long run, the negative effect of selling it is far greater than the positive significance.

The current post bar is in a very embarrassing situation-it is a product with hope but no future.

Although the Post Bar has declined, the skinny camel is bigger than the horse. It still has a monthly life of tens of millions, a large number of high-quality content and old users scattered in every corner of the Internet. The incident of "Our family is rich" also proves that its powerful stalk-making ability is still there. If we can make some innovations, it may not be hopeless.

However, Post Bar, which hasn’t brought much revenue, has become a marginal business in all in AI and Baidu with smart cars. It doesn’t have much resources to make changes related to the underlying architecture, and it can only be like an old warrior. He died slowly and painfully in the corner alone.

The history of the rise and fall of Baidu Post Bar is worthy of reflection by all content platforms, to think about how to find a balance between user experience, content quality and commercialization, to understand the social responsibility that C-end products must bear due to their natural social attributes, and to reflect on the disastrous consequences when KPI becomes the only goal.

In 2016, an insider of Baidu once said after the hemophilia bar incident: "It’s not too late for Baidu to mend today, and even posting it is not necessarily a bad thing for Baidu. Tencent in that year was also openly written on the cover by an Internet magazine, which led to later reflection and Tencent’s open platform, and today’s Tencent."

It’s not too late to mend after it’s too late, but it depends on whether Baidu cares about the life or death of that sheep.

Listening to insiders reveal the realization of Baidu Post Bar, three lessons.

　　Xinhua News Agency, Chongqing, January 25th　Question: How much "oil and water" is there in "hot pot old oil"? — — Investigation on the problem of "hogwash oil" in Chongqing hotpot

　　Xinhua News Agency reporters Ke Gaoyang and Han Zhen

　　Chongqing Food and Drug Administration recently issued an announcement to investigate five hot pot restaurants suspected of recycling "old hot pot oil", and informed or transferred relevant clues suspected of food safety crimes to the public security organs, thus unveiling a new round of rectification of Chongqing hot pot industry.

　　The so-called "old chafing dish oil" which is recycled repeatedly is actually the "swill oil" which is the same as the waste oil. It has long been banned because of its harm to human health, but it has been banned in Chongqing chafing dish industry for many years. The reporter’s investigation found that the use of "swill oil" can make huge profits and is difficult to find, and the illegal cost is extremely low. It is urgent to strengthen the rectification from the source to prevent "swill oil" from flowing to the table.

　　How big is the huge profit behind the "swill oil"?

　　“‘ Hogwash oil ’ Repeatedly banned, the biggest reason is driven by huge profits. " An industry insider who has been engaged in Chongqing hot pot business for more than 20 years calculated an account for the reporter: 1 kg of hot pot bottom material costs 15-20 yuan. Generally, 2-3 kg of hot pot bottom material is used for small pots and 4-5 kg for large pots, but the bottom cost of most hot pot restaurants is only about 30-50 yuan, which is not enough. With the use of "swill oil", the oil consumption of the cauldron is about 1.2 kg, and that of the small cauldron is about 0.8 kg. The remaining 60% to 70% of the oil can be recycled, and more than half of the cost saved is the net profit of the merchant. If a hotpot restaurant receives 30 tables every day, the use of "hogwash oil" can save more than 1,000 yuan in cost and increase tens of thousands of yuan in income in one month.

　　According to the insider, over the years, Chongqing hotpot enterprises that use "hogwash oil" have formed a set of relatively fixed processing flow: the chafing dish bottom material recovered from the dining table is first filtered through a sieve to separate the oil residue, and then dried at a temperature of 100-120 degrees Celsius for oil-water separation. After the separation, add spices for refining, and then serve them on the table again. In order to better separate the residue in the "swill oil", some merchants have to carry out high-temperature washing.

　　The reporter’s investigation found that in addition to directly processing "swill oil" in the store, some hot pot restaurants choose to sell "swill oil" to small workshops and process it into "gutter oil" in the underground market.

　　The manager of a hot pot restaurant in Yubei District of Chongqing told the reporter that his hot pot restaurant needs to deal with 2 to 3 tons of hot pot "hogwash oil" every month. If it is sold to a small workshop at the purchase price of 10 yuan per kilogram, it can earn 40,000 to 50,000 yuan more each month. Although the hot pot "hogwash oil" is recycled by a company certified by the environmental protection department, "if ‘ Hogwash oil ’ Give it to them, not only can’t sell money, but you have to pay a handling fee. Who wants this? " He complained.

　　How difficult is it to control the "swill oil"?

　　"Illegal use of ‘ Hogwash oil ’ It can bring rich profits, but it is very difficult to collect evidence and investigate related behaviors. " Chen Honggang, deputy director of the Food and Drug Administration Branch of Jiangbei District, Chongqing, said that in recent years, the food and drug administration has continuously cracked down on "swill oil", but it has been repeatedly banned, and the method of illegal merchants using "swill oil" has become more and more concealed.

　　Some unscrupulous merchants choose to cook "swill oil" after the end of business at night, and then put it into disposable packaging bags to deceive consumers; Some unscrupulous merchants use high-purity filtration or mix with qualified edible oil, which makes it difficult to distinguish "swill oil" and it is difficult to obtain evidence for law enforcement.

　　On January 10th, Chongqing Food and Drug Administration inspected the captain’s theme hot pot Beicheng Tianjie Store suspected of using "swill oil". After the reporter followed the law enforcement officers into the hot pot restaurant, the chef found that the restaurant had a camera in the kitchen, but the chef in the store said that the camera had never been used. "In this case, even if the store directly processes and uses it in the kitchen ‘ Hogwash oil ’ It is difficult to directly confirm without surveillance video. " Relevant people said.

　　According to relevant sources, at present, there is still a lack of corresponding technical standards and detection methods for the identification of "hogwash oil" in China, which means that if "hogwash oil" is not "one pot at a time" in the initial and intermediate stages, once it is put on the market for sale and use, it is less likely to be discovered.

　　In addition, the high cost of consumer rights protection has also contributed to the arrogance of merchants using "swill oil" in disguise. Zhang Zhongmin, a member of the Expert Advisory Committee of china law society Food Safety Research Center and a professor at chongqing technology and business university Law School, pointed out that the use of "hogwash oil" in hot pot restaurants is harmful to consumers’ health and belongs to universal infringement. However, this damage is not obvious. If consumers initiate rights protection, it will take time and effort, but the compensation will be limited, and they will face difficulties in proof, which will make unscrupulous businesses hide.

　　How to cure the hot pot "swill oil"?

　　"Swing oil" has many harms but no benefits, but it is an open secret or even a "hidden rule" in Chongqing hot pot industry. Some consumers exclaimed, why is it so difficult for ordinary people to eat a safe and secure hot pot?

　　Statistics show that as of the first half of 2017, there were nearly 30,000 hot pot stores in Chongqing, with an output value of 30 billion yuan. Experts say that if there is no scientific and effective way for such a large number of industries, it is easy to cope with them and it is difficult to supervise them.

　　Experts such as Associate Professor and Jing Jun from the School of Politics and Public Administration of Southwest University of Political Science and Law believe that countermeasures should be sought from the root causes, the initial link of "swill oil" should be grasped, clear standards should be set for the treatment of kitchen waste in catering industries such as hot pot, monitoring systems should be installed, bright kitchens should be built, and the whole recycling process should be supervised and covered.

　　Finding a way out for "swill oil" is also an important way to solve the problem. The main component of "swill oil" is grease. Although it is not suitable for eating, it can be made into industrial products such as soap and lubricant, and its application market is broad. Experts suggest that in order to improve the enthusiasm of catering enterprises to recycle kitchen waste such as hot pot swill oil through formal channels, we can learn from foreign experience and encourage professional companies to buy swill oil at a certain price by means of government subsidies, so as to turn a huge amount of kitchen waste into treasure and prevent swill oil from flowing to the table at the source.

　　Total fundraising decreased by nearly 80% year-on-year.

　　According to the statistics of our data center, including Shanghai Electric’s non-financing IPO, 77 companies have appeared in Shanghai and Shenzhen stock markets through IPO since 2008 (6 main board companies in Shanghai stock market and 71 small and medium board companies in Shenzhen stock market). Except for Shanghai Electric, 76 companies raised a total of about 103.4 billion yuan, with an average price-earnings ratio of 27 times.

　　Since the beginning of this year, due to the deep adjustment of the stock market, the number of IPO companies and the total amount of funds raised have been greatly reduced compared with last year. The industry believes that the IPO is less likely to open in the remaining ten trading days of the year. Optimists predict that if the market is optimistic, it is expected to restart the IPO； in January or the first quarter of next year; However, pessimists said that the current market expansion pressure is still great, and it will take time to open the gate.

　　77 new faces appeared

　　Since January 1, 2008, the Shanghai Composite Index has dropped from a high of 5,522 points to 1,954 points on December 12, with a drop rate of more than 60%. The deep adjustment of the market not only makes investors "suffer huge losses", but also greatly reduces the scale of IPO.

　　According to the statistics of our data center, in 2007, a total of 123 companies were listed on the A-share IPO, including 23 main board companies and 100 small and medium-sized board companies in Shanghai. The total amount of funds raised was about 477 billion yuan, with an average price-earnings ratio of 30 times.

　　Compared with 2007, the number of companies listed through IPO in 2008 decreased by 38%, the total amount of funds raised decreased by 78%, and the average P/E ratio decreased by 10%.

　　In addition to the sharp slowdown in the pace of issuance, there have been few large-cap IPOs this year, with only five companies issuing more than 500 million shares, accounting for 6% of the total number of IPOs, compared with 17% last year. However, although the number is small, large-cap stocks still play a major financing role. The five companies raised a total of 73.3 billion yuan, accounting for 70% of the total IPO funds raised this year.

　　Among the 76 IPO companies this year, China Coal Energy raised the highest amount of funds, reaching 25.6 billion yuan; China South Locomotive issued the largest number of shares, with 3 billion shares; The number of shares issued by Chuanda Zhisheng, which was listed on June 23rd, is the smallest, only 13 million shares. Teerjia, which went public on February 1st, raised the least amount of funds, amounting to 122.2 million yuan.

　　At the same time, due to the continuous decline of the market, the increase of IPO on the first day of listing is also very different. Huarui Cast Steel, which was listed on January 16th, issued 54 million shares, raising 580 million yuan, with an opening increase of 206% and a closing increase of 189%. Huachang Chemical, which was listed on September 25th, issued 51 million shares and raised 510 million yuan, with an opening increase of only 75% and a closing increase of 85%.

　　From the industry point of view, in 2007, 10 financial and insurance companies went public through IPO, while in 2008, the number was 0; Among the IPO companies this year, the two industries with the largest proportion are machinery, equipment, instrumentation and petrochemical plastics, with 16 and 14 companies respectively.

　　Judging from the month of IPO issuance, there were at least four in March this year; At the peak in May, 18 companies were issued and listed. Up to now, no company has listed on the IPO in the fourth quarter.

　　It is worth noting that although Shanghai Electric, which landed on the Shanghai Stock Exchange on December 5, was also in the form of IPO, it adopted the method of exchanging shares to absorb the shares of Shanghai Power, and did not raise funds from the market.

　　The IPO has not been reviewed in the past three months.

　　Since Huachang Chemical landed in Shenzhen Small and Medium-sized Board on September 25th, the domestic A-share IPO has been at a standstill. Not only that, the IPO audit has also entered a "frozen period". Since the initial application of Hunan Boyun New Materials Co., Ltd. was approved by the Audit Committee of China Securities Regulatory Commission at its 135th meeting in 2008 on September 16, 2008, the Audit Committee has not conducted IPO audit for nearly three months by December 12, 2008.

　　According to the data of Wind, there are 33 companies that have "passed the meeting" but are still waiting in line for listing, including China Construction, Everbright Securities and China Merchants Securities. Among them, the first application for China Building was approved on June 5th, and it has been more than six months since then.

　　However, it is not just domestic A-shares that are stagnant in IPO. In the context of the global financial crisis and the sharp turmoil in the stock market, the global IPO process has slowed down significantly, especially in the United States. According to reports, since the last IPO on August 8, the US IPO market has been completely frozen, and there has been no harvest for several months, setting a record for the longest "vacuum period" of US IPOs since Thomson Reuters tracked statistics in 1980. Some people joked that American IPO entered the hibernation period ahead of schedule, and many bankers and investors have basically begun to pay attention to IPO activities next year, but no longer care about the rest of 2008.

　　When will the gate open?

　　Although there are still 13 trading days left in December, the industry believes that the possibility of restarting IPO this year is very small.

　　According to Wind data, the number of shares released in December reached 25.256 billion, second only to 27.55 billion in August, which was the second largest peak of lifting the ban in the year, and the financial pressure was still great.

　　Liu Jiazhang, a strategist at National Securities, said that the current market financing function depends entirely on the quality of the market. If there is a cross-year market, there may be some small and medium-sized board IPOs tentatively in January or the first quarter of next year.

　　Unlike Liu Jiazhang’s optimistic expectations, most people in the industry are relatively pessimistic. Xu Haiyang, chief strategist of Nisshin Securities, said that the current market environment does not have the conditions to restart the IPO, and there is no hope that the IPO will open for at least three months. The economy is located in the deceleration cycle, and the secondary market is expected to expand greatly, which greatly affects the market financing function.

　　Xu Wei, a strategic researcher at Guojin Securities, also said that it may be at the end of the first quarter and the beginning of the second quarter at the earliest, the Central Economic Work Conference proposed to maintain the stable and healthy development of the capital market, and the management will also consider the market situation more.

　　At present, the important problem to be solved in the stock market is not to promote more corporate financing, but to solve the "sequela" problem of share reform and expansion reasonably and smoothly. According to the statistics of brokers, the total number of "non-size" lifting the ban will reach 687.024 billion shares next year, which is the highest peak in the history of "non-size" lifting the ban, equivalent to 4.2 times the number of lifting the ban this year. After the lifting of the ban, the proportion of A-share tradable shares in the total share capital will soar from 37% at the end of 2008 to 74% next year.

　　Xu Haiyang pointed out that the focus of the macro-economy in the future is to maintain growth, and the focus of the capital market in one or two years is to solve the problem of expansion. Even if the newly listed stocks are not considered, the market value of tradable shares will expand by about three times in the next two years. Earlier, it was reported that the audit committee "dismissed" some companies that queued up for the meeting, which also reflected the management’s orientation. The capital needs of more companies may need to be realized through other channels than the stock market.

　　In addition, for the Growth Enterprise Market, Xu Wei analyzed that the Growth Enterprise Market will be launched when the market is stable, and it may take one or two hundred companies to launch at once when the Growth Enterprise Market is just launched, so that the market scale will rise and it is possible to trade and invest. However, the large-scale launch has great pressure on the market. Therefore, the management will first consider the opening of IPO in Shanghai and Shenzhen stock markets and slowly "release" the companies waiting in line for issuance. (Reporter Wang Jin)

What is a "cigarette card"? Is it necessary to stop the "smoking card" game in primary and secondary schools?

AI answer

The "cigarette card" is to cut the cigarette label from the cigarette box and fold it to make a card with the size of a card. The game is relatively simple. Students get together and hit the ground with their empty palms. If the "cigarette card" is hit by the palm wind, it will win.

Most of the "cigarette cards" in children’s hands are cigarette cases picked up on the road, trash cans, mahjong parlors, etc., or asked for from family members who smoke, and then the "hat" of the cigarette case is taken off and folded into a rectangular card. Its value is divided according to the brand price of cigarettes or the degree of market circulation. Whoever owns more cards and is expensive will have the capital to show off.

Whether it is necessary to stop the game of "smoking cards", which is popular among primary and secondary school students, is a problem worthy of in-depth discussion.

First of all, it needs to be clear that "cigarette card" is a game prop made of discarded cigarette cases, which is related to tobacco products. This connection may make primary and secondary school students unconsciously come into contact with tobacco products, thus generating curiosity about smoking. Considering the harm of children smoking prematurely, it is necessary to prevent the popularity of "smoking cards".

Secondly, primary and secondary school students are in a critical period of physical and mental development, and their values and behavior habits are being formed. The popularity of "smoking cards" may lead primary and secondary school students to indulge in games excessively and neglect their studies and other more beneficial activities. In addition, primary and secondary school students may have the psychology of keeping up with the joneses because of the "cigarette card". Therefore, from the perspective of education, it is of certain significance to prevent the popularity of "smoking cards".

However, primary and secondary school students’ curiosity and desire to explore new things also need attention. As a novel game prop, "cigarette card" may attract their attention, thus avoiding them from indulging in electronic products. In this case, appropriate guidance should be given to help them understand the risks of the "smoking card" game, discuss with them how to treat the "smoking card" game correctly, and encourage them to explore healthier and more beneficial games and activities.

For the "smoking card" game, it is more necessary for schools, families and society to work together to guide children correctly. At the same time, it is also necessary to pay attention to children’s psychological needs, lead children to go outdoors, participate in badminton, football and other activities that are beneficial to physical and mental health, stimulate their more hobbies, create more games and activities that are beneficial to physical and mental health, and help them grow up healthily.
