Meituan’s lawyer’s letter of living expenses is a legal document issued by Meituan’s financial department for users and law firms with outstanding loans. This is usually a formal warning to remind users that they have failed to fulfill the agreed obligations in the loan contract and urge them to repay as soon as possible. It usually comes from the legal means that users will take further when they are in arrears for a long time or have failed to collect for many times. After receiving the lawyer’s letter, the user may face further legal investigation, which needs to be taken seriously and dealt with in time.

After receiving the letter from the lawyer of Meituan’s living expenses, users need to realize that this is not just an ordinary collection, but a prelude to possible legal procedures. If the outstanding loan is ignored or continued, the collector may apply to the court for prosecution. After the court ruling, users may face enforcement measures, such as freezing bank accounts, inquiring about property status or even losing the right to dispose of some property or assets under their names. If the user is included in the list of people who have broken their trust, it may also affect normal life and credit activities, such as restricting high consumption, restricting the application for loans or credit cards. In order to avoid these consequences, measures should be taken in time after receiving the lawyer’s letter.

After receiving the letter from the living expenses lawyer of Meituan, it is necessary to confirm the authenticity of the letter. Usually, a formal lawyer’s letter will clearly indicate the name, address and contact information of the law firm, with the lawyer’s signature or firm seal attached. Users can verify the source of the letter by official website of the law firm or calling the public telephone. The customer service channel of Meituan’s living expenses is also an important way to confirm. You can directly call the customer service of Meituan Financial Platform for verification. Don’t call the strange private number in the letter at will, and beware of fraudsters committing fraud in the name of lawyer’s letter.

When you receive the letter from the lawyer of the US Mission’s living expenses, don’t panic or ignore it. Contact the official customer service department of Meituan at the first time to find out the unpaid amount, interest accumulation and specific situation, and confirm the authenticity of the letter. If it is true that the overdue payment is overdue, you should try to negotiate with the US delegation-explain your financial difficulties and strive for a plan of deferred repayment or installment repayment. You can also consult a lawyer to confirm whether you have any legal rights to claim. If you are unable to repay the debt, you can consider signing a written repayment agreement with the platform, and don’t delay the handling at will, otherwise it will have more serious legal consequences.

Receiving a letter from a lawyer of the US Mission’s living expenses does not mean that it will definitely face legal proceedings immediately. The lawyer’s letter is more of a warning to the borrower, urging the other party to fulfill its contractual obligations as soon as possible. Whether it will be prosecuted or not depends on the user’s subsequent reaction and attitude towards the letter. If the user pays off quickly after receiving the lawyer’s letter or reaches a repayment agreement with Meituan, it is usually less likely to sue; On the contrary, if users continue to default or fail to respond, they are more likely to be sued. Users should actively respond to lawyers’ letters and try to reach a settlement with Meituan before litigation.

The overdue Meituan living expenses loan has already had an impact on the user’s credit record. If the user fails to repay the loan on time, the default record will be reported to the central bank’s credit information system, which will seriously affect personal credit information. The receipt of a lawyer’s letter shows that the overdue situation has become more serious and the credit risk of users has already appeared. After being sued, once the court decides that the borrower needs to perform the contract and refuses to perform it, it may be included in the list of people who have lost their trust (commonly known as "Lao Lai"), which greatly lowers the personal credit score. After receiving the lawyer’s letter, we should try our best to solve the problem through consultation to avoid credit stain.

Generally, the lawyer’s letter of the US Mission’s living expenses will explain the specific amount that the user needs to repay, including principal, interest, late fees, attorney fees and other related expenses. These fees are calculated according to the terms of the loan contract or the platform agreement, and users need to check them item by item. For example, the late payment fee is the penalty fee due to overdue, while the lawyer’s fee is the cost incurred by the platform to hire a law firm to send letters and subsequent possible lawsuits. Some interest may be calculated on a daily basis, which also requires users’ special attention. If you are in doubt about the details of the fee, you should contact the relevant departments as soon as possible to verify.

The core of preventing receiving the letter from the lawyer of the US Mission’s living expenses is to fulfill the repayment obligation on time. Users need to evaluate their repayment ability and plan the loan amount and term reasonably before borrowing. In the process of repayment, we should pay attention to the monthly repayment time and try to prepare repayment funds in advance. In case of sudden financial difficulties, you should contact Meituan’s living expenses customer service in time, explain the situation and apply for deferred repayment or adjust the repayment plan. Reminders can be set, such as mobile phone calendar reminder or binding automatic deduction, to ensure that the repayment time limit is not missed due to negligence, and to fundamentally avoid receiving a lawyer’s letter.

　　Whether to eat rice or noodles is always a controversial topic. Let’s divide into several questions and take a quick look.

　　Question 1

　　Compared with the staple food made of white flour, which one has higher calories?

　　As far as the calorie of food is concerned, it is not what food is made of, but what it is made of, how much water it contains, how much dry food it has, and whether it is added with oil and sugar. The reason why pasta is generally higher in calories is because of the above two reasons.

　　A lot of pasta needs oil, even both oil and sugar. Most of those foods with stuffing have fat and thin meat stuffing and enough fat. Therefore, compared with rice, these pasta dishes have higher calories, which is understandable.

　　Those pasta without oil and sugar depend on the moisture content. The moisture content of ordinary white rice is usually between 62% and 65%. Except for soft noodles, pasta will probably be lower than this value. For example, the moisture content of steamed bread is about 45%-50%, and the staple bread is even lower, only about 40%. As for dry staple foods such as naan, steamed buns and dry pancakes, the moisture content is even lower.

　　Because the water content is low, eating a little more will increase the calories. Comparatively speaking, rice has more water content, less dry goods and lower calories. If you cook porridge again, it will contain more water and have lower calories in each bite.

　　Therefore, compared with the same dishes, when eating rice or porridge, the quantity is better controlled, and the risk of excessive calories is slightly smaller.

　　Question 2

　　Compared with the staple food made of white rice and white flour, which one has higher blood sugar response?

　　In terms of blood sugar reaction, white rice and white flour food are generally high, depending on the cooking method.

　　Compared with white steamed bread and white bread, the glycemic index (GI) of rice is slightly lower, but not much lower. White steamed bread and white bread are 88, and white rice is 83. Whole wheat steamed bread and whole wheat bread will raise blood sugar more slowly.

　　For those pasta with added fat, although the digestion speed is slow and the blood sugar rises later and lower after a meal, the food with high fat has an adverse effect on the insulin sensitivity of the next meal. Therefore, it is not a good choice for people who need to control blood sugar, and it is not a good choice for people who need to lose weight.

　　Among pasta, pasta and macaroni have the lowest blood sugar reaction, and ordinary dried noodles are lower than steamed bread. Generally speaking, the higher the content of protein in flour for noodle making, the more chewy the cooked taste, and the lower the postprandial blood glucose response.

　　Similarly, rice also has different processing accuracy and processing methods. If you eat germ rice, rice with some brown rice, etc., then under the premise of the same cooking method, the GI value is lower than that of polished white rice. There are also some boxed ready-to-eat rice processed in advance, and the GI value is lower than that of freshly cooked rice at that time.

　　Of course, the GI value of these rice is lower than that of steamed bread and bread. Therefore, from the perspective of blood sugar stability, ordinary rice has a slight advantage.

　　Question 3

　　Is there any rice food with a higher blood sugar response than white rice?

　　Among white rice foods, there are indeed some foods with higher blood sugar response than bread and steamed bread, that is, white rice porridge and glutinous rice food.

　　White rice porridge cooked with refined white rice is very easy to digest because it is boiled to powder, so its blood sugar response is higher than that of white rice.

　　However, these foods are similar to rice. Although the blood sugar peak is steep, it is not easy to cause hypoglycemia. What is more powerful is glutinous rice food. After eating them, not only did their blood sugar rise sharply, but according to the same amount of carbon and water, their postprandial blood sugar was easy to drop below the normal level.

　　So, what if you add oil to glutinous rice food? Blood sugar will rise a little later, but the peak of blood sugar in the later period is big and lasts for a long time. Of course, this kind of food is added with fat and has more calories than white rice, which is not suitable for people who need to lose weight.

　　Therefore, for unhealthy people who have already suffered from cardiovascular diseases or diabetes, glutinous rice foods such as fried cakes, glutinous rice balls and zongzi, as well as refined white rice foods such as rice rolls and preserved egg porridge, need to be controlled even more, because their GI values are really too high, even higher than ordinary white rice.

　　Therefore, from the perspective of controlling blood sugar, glutinous rice food is the worst, worse than white bread and steamed bread.

　　Question 4

　　How to match rice food and pasta with whole grains?

　　Rice can be incorporated into countless kinds of whole grains and legumes to make miscellaneous grains rice. Half white rice and half other miscellaneous grains (most of which need to be soaked in advance) actually taste very fragrant. It is also very simple and convenient to add some diced sweet potatoes, Chinese yam slices and taro seeds when steaming rice.

　　Flour can also be added with about 20% of miscellaneous grains powder to make steamed bread, cakes, pancakes, bread and so on. However, when the addition amount exceeds 20%, the taste of pasta will become worse because gluten is seriously diluted. A small amount of mixed bean powder can be added to the noodles, which makes the taste smoother. You can also add oat flour, buckwheat flour, corn flour, etc., but the toughness of the noodles is reduced, and the cooking method is different. Home-made technology is difficult, and the overall popularity is not high.

　　Therefore, from the convenience of adding whole-grain miscellaneous beans and potatoes, rice has a slight advantage.

　　Question 5

　　Are there enough dishes to accompany the staple food?

　　Although the postprandial blood sugar response of white rice is higher than that of noodles, jiaozi and Melaleuca Cake, many people find that eating rice has better blood sugar control effect than eating these pasta, and it is also less likely to gain weight. Why is this?

　　To a large extent, this is because of different eating methods and different contents.

　　In addition to the low nutritional value of white rice, there are advantages in food collocation when eating rice. We seldom just eat a bowl of rice, but we have meat, fish, eggs, bean products, and vegetables, and usually there are more dishes than rice. This makes it easier to obtain relatively balanced nutrition.

　　When eating noodles, there is a big bowl of noodles, and there are only a few dishes and marinades. Therefore, from the perspective of fully cooperating with various dishes, rice is still slightly dominant.

　　Question 6

　　Which vitamin is more, rice or pasta? Which is safer?

　　Comparing rice with white flour one-to-one, protein and B vitamins in white flour are slightly higher. However, the disadvantages of rice are not so obvious after matching dishes. Rice with a large number of dishes, compared with noodles and cakes with few dishes, nutrition will win.

　　From the safety point of view, rice food rarely has allergic problems, while some people eat flour with the risk of "chronic gluten allergy". For these allergic people, wheat gluten will damage the intestinal mucosal barrier, which may lead to chronic allergies to other foods. Severe wheat gluten allergy may even lead to "celiac disease". Such patients can lead a normal life only if they are completely away from all foods containing flour.

　　Generally speaking, rice food and pasta have their own advantages and disadvantages. Whether it is white rice or white flour food, eating more is not conducive to preventing diabetes and cardiovascular and cerebrovascular diseases, nor to losing weight. Appropriate inclusion of whole grains is a better choice. For people who need to lose weight and prevent chronic diseases, reducing the oil and salt in the staple food, including some whole-grain miscellaneous beans and more vegetarian dishes are the key points to eat the staple food healthily.

　　Text/Fan Zhihong (director of China Nutrition Society, chief expert of science communication hired by China Association for Science and Technology)

　　Both consumers and employees in the automobile industry scoff at the mention of fake cars, but whether you admit it or not, the history of China cars is composed of one fake car after another. A few days ago, Autocar, a famous British automobile professional media, claimed that China’s automobile industry likes to copy cars with the title of Dead Ringers: History of the Chinese Copycat Car (A Goods: History of China Counterfeit Cars), and counted the most outrageous cases of China Counterfeit Cars. The original text is compiled as follows.

　　China knockoffs are rapidly becoming the main force in the local market, as shown by Zotye SR9 and Vekery V7, and they even make no secret of imitations from Porsche Macan and Volkswagen e-Up.

　　In recent years, China’s automobile industry has got rid of imitation, and many independent brands have even launched landmark competitive new cars in Europe and the United States. However, even the biggest brands have more or less had shanzhai cars in their product lineup. Therefore, please follow us to see the most outrageous knockoffs in these years.

　　Great Wall Euler R1—— Imitating Honda E and smart forfour

　　The Great Wall Euler R1 is a car made by Great Wall Motor Company, mainly for young people in cities. Its profile is exactly the same as that of smart forfour, and the front air intake grille is very similar to that of Honda E. Obviously, the name of OLA stands for "Open, Reliable and Alternative fuel", but the top speed of this mini-car is 100 km/h, which is slightly lower than that of Honda E’s 145 km/h.

　　Lifan 320-Imitate the MINI hatchback version.

　　The 320 is a 1.3-liter mini-car produced by Lifan Automobile, which was launched in the world at the 2008 Beijing Auto Show. Lifan 320 is notorious for being very similar to the MINI hatchback. In 2013, lifan 320 ushered in a redesign. After the redesign, it is no longer similar to the MINI hatchback version, but now it is more like the Fiat 500-which is amazing.

　　Landwind X7-Imitating Land Rover evoque

　　Landwind X7 was launched in 2014, and attracted much attention because it is very similar to Land Rover evoque. In fact, Land Rover was dissatisfied and took Landwind X7 to court. Although the government of China is on the side of Landwind, the price of Landwind X7 is only 14,000 pounds (about 124,000 RMB).

　　Double-ring SCEO-Imitating BMW X5

　　The front face of the double-ring SCEO may be more like the first generation Lexus RX, but there is no doubt that its outline and tail are more influenced by BMW X5. Of course, BMW will not stay out of it and take the double-ring SCEO to court. As a result, the double-ring SCEO was banned in Germany.

　　Red Scorpion in the Great Wall —— Imitating Audi R8

　　You may think that this unique shape will only appear on the Audi R8, but Great Wall Huaguan Automobile likes this design very much, so it decided to adapt it to its electric supercar Red Scorpion. The front and back design of the Great Wall Huaguan Red Scorpion is quite eye-catching, and it is not quite like Audi R8, but the outline is undoubtedly from Audi R8.

　　Changan X70A-Imitating Land Rover Discovery 4

　　For the master designer of China shanzhai cars, even the models that have not stopped production are safe. Changan X70A is a large-size SUV, produced by a car manufacturer from Chongqing, and its design is inspired by Land Rover Range Rover Discovery 4. Although the front face looks different, the profile of Changan X70A undoubtedly originated from the discovery of Land Rover.

　　Geely beauty leopard-imitating modern coolpad

　　In order to prove that the culture of China’s fake cars is nothing new, Geely Beauty Leopard successfully drew design inspiration from the front face of Hyundai Coolpad and the tail of Toyota Supra. Fortunately, Geely did not adopt the same design method for Volvo.

　　Ranger x-imitating Tesla Model S

　　Ranger is the Chinese name of Knight Rider. The internal and external design of Ranger X is very similar to that of Tesla Model S, and it is equipped with LCD lights in the style of KITT. The official said that it can accelerate 0-100 km/h in 5.6 seconds, with a cruising range of 460 km. At that time, Tesla declined to comment on this car.

　　Double-ring aristocrat-imitating smart fortwo

　　Don’t be deceived by the name Noble. This car is neither a replica of Noble M600 (the supercar launched by British sports car manufacturer Noble at the Frankfurt Motor Show in 2009), nor is its design intention noble. Although the appearance is similar to the two-seat smart fortwo, the double-ring aristocrat has four seats, but it is not clear how comfortable these four seats are.

　　Daojue Pioneer S-Aston Martin Cygnet

　　If you really want to choose an Aston? Martin’s car is a fake, and you certainly won’t choose Cygnet. But that’s what Dow Jones did. Pioneer S is an electric cottage car of Cygnet mini-car. In fact, Cygnet itself is based on Toyota iQ. Although it is not imitation, we should also indicate it. The Trailblazer S has a cruising range of 120 kilometers and a maximum speed of 60 kilometers per hour.

　　Yujie S325-Imitating Land Rover evoque

　　As a cottage car, Yujie S325 is still an innovative product. Its front face and taillights are miniature versions of Land Rover evoque, and everything else shows a tall and ugly mini-car. We don’t think Jaguar Land Rover will suffer from the impact of Yujie S325 on sales in evoque.

　　Yujie 330-Imitating Kia Picanto

　　Although the starting price of Picanto is only 7,495 pounds (about 66,000 RMB), Kia may be dissatisfied with another car of Yujie. Yujie 330 is one of the most similar cottage cars we have ever seen, but for Yujie 330, finding market living space is the real test.

　　Geely, USA and Japan 300-Imitating mercedes benz c Class

　　The tail of Geely Meiri 300 imitates another unknown China car, and the front face imitates the mercedes benz c class, even without any slight adjustment or change. It is completely the front face of the mercedes benz c class car, supplemented by the engine cover logo inspired by the Mercedes-Benz Trident Star Emblem.

　　Zotye SR9-Imitating Porsche Macan

　　The body of Porsche’s best-selling car Macan was transformed into Zotye SR9. Zotye SR9 is sold in China at a price of 12,300 pounds (about 109,000 RMB). It is equipped with a 2.0-liter turbocharged four-cylinder gasoline engine from Mitsubishi, with a maximum power of 187 HP and a peak torque of 250 Nm.

　　Vickery V7-Imitating Volkswagen e-Up

　　The newest member of the cottage family is Vicory V7, or, in layman’s terms, the Volkswagen e-Up clone. Wei Kerui V7 even imitates the brand logo of the front face, just like the BMW logo of the next cottage.

　　BYD Logo-Imitating BMW Logo

　　The BMW round logo design has also been copied, although the form has been adjusted. Although it is more decent than the cottage car, it is obvious where the font, color scheme, shape and layout of BYD logo come from. BMN, a China clothing brand, is also facing a lawsuit from BMW for its round logo. But that’s all.

　　Although the comments of British media Autocar are full of arrogance and disdain, the cottage car has always been a topic that cannot be avoided in the development of China’s automobile industry, and it is also a microcosm of the history of China’s automobile industry. Thanks to the unremitting efforts of several generations of China autobots, the pace of catching up with the century-old automobile manufacturing power has been accelerated, the gap has been continuously shortened, and more and more autonomous vehicles have gone abroad to enter the European and American markets. For more information about China shanzhai cars, please pay attention to the follow-up reports of Sina Auto. (Source: autocar Compilation: Zhang Jidong)

　　The project involved in the 863 Program is actually a study on the safety of functional food, and the purpose of the study is not to extend the life.

　　On December 5th, Weibo, the official website of Wang Laoji, announced that according to the research results of the National 863 Program, drinking Wang Laoji can prolong life span by 10%. After this statement was released, it was quickly questioned by netizens about the authenticity of the project and the scientific nature of its conclusions. Beijing Youth Daily reporter found that herbal tea brands such as Wang Laoji were indeed used as experimental objects in a sub-project of the 863 Program. However, according to the introduction of Guangzhou CDC, which participated in the project, the center has only done relevant experiments on rats, and it is not sure that the effect of "prolonging life" is also applicable to humans. Many experts in related fields said that there is no functional food, even medicine, that can claim to prolong human life by 10%.

　　Wang Laoji claims to prolong his life by 10%

　　On December 5th, a news about herbal tea Wang Laoji was widely spread on the Internet. Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, announced at a forum that the research results of the National 863 Program show that drinking Wang Laoji can prolong life by about 10%. But soon this news caused a lot of questions.

　　The first person who questioned this idea was the CEO of Huada Gene in the same industry. On the afternoon of the 5th, Weibo, the official of Wang Laoji, announced that Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, had a high-end interaction with Yin Ye, CEO of Huada Gene, and other guests at the China Medical Industry Forum. Li Dong said that "according to the research results of the National 863 Program, drinking Wang Laoji can prolong the life span by about 10%", which was immediately highly recognized by President Yin Ye of Shenzhen Huada Gene Co., Ltd. and warmly applauded by all the guests.

　　On the afternoon of 6th, Yin Ye, CEO of BGI, forwarded the Weibo and explained that the so-called "high recognition" was just a courtesy nod. He said: "Although I am in the same industry and drink Wang Laoji, it does not mean that I recognize this conclusion. The extension of human life span is a comprehensive issue, and so far no single factor can form such a significant difference. "

　　In addition to peers, many netizens have also left messages under Wang Laoji’s official Weibo, saying, "Believe in advertising, you can prolong your life by 100%, just give your brains.". Others questioned, "How is 10% calculated? So many health products in China didn’t dare to say that, and finally lost to a drink seller. ".

　　Previously, it was caught in the "life extension storm"

　　The reporter of Beiqing Daily found that this is not the first time that Wang Laoji claimed that he has the effect of prolonging his life. On June 13th, 2013, GPHL held a special press conference, saying that "Wang Laoji Herbal Tea has the function of prolonging animal life".

　　At the press conference, GPHL said, "Through a two-year safety test on 576 mouse samples, it was initially found that the survival rate of rats in the experimental group of Wang Laoji herbal tea was better than that of the control, indicating that Wang Laoji herbal tea has the function of prolonging animal life … …”

　　At that time, it was not long before Guangzhou Pharmaceutical officially recovered the brand of Wang Laoji, and the news about "Wang Laoji prolonging life" immediately caused widespread doubts. Some netizens said, "How long does it take to extend the life of animals to be scientifically verified? It was less than two years before Guangyao officially recovered Wang Laoji, and this magical result was actually measured! " Others ridiculed, "After Radix Isatidis, another dose ‘ Shenyao ’ Available. "

　　Despite the surging doubts, the relevant person in charge of Guangzhou Pharmaceutical firmly believed in the authenticity of the efficacy of prolonging life when interviewed by the media, and said that this was only a phased achievement, and the next step would be to continue research.

　　Sure enough, on January 6, 2016, Wang Laoji once again released a "breakthrough" scientific research achievement: according to national standards and US FDA standards, the three-year safety system study of the first herbal tea product in China showed that long-term drinking of Wang Laoji herbal tea could prolong the life of animals.

　　According to reports, this conclusion is the first herbal tea project in the National 863 Plan. Guangdong Provincial Center for Disease Control and Prevention, as a scientific research unit, undertook the research on functional food safety evaluation factors.

　　"According to the requirements of national standards and American FDA standards, the research group conducted a two-year safety system study on mouse samples, and found that the survival number and expected average survival time of the experimental group of Wang Laoji herbal tea were higher than those of the control group. The statistical survival time of the experimental group of female rats given 2.90g/kg BW of Wang Laoji herbal tea was 708.2 days, while the statistical survival time of female rats in the control group was 675.1 days, which was 33.1 days higher. The difference was obvious, which proved that drinking Wang Laoji herbal tea for a long time could prolong the life of animals. At the same time, related research was carried out according to the human consumption rules of functional foods, and it was found that the physical examination indexes such as liver and kidney function, blood lipid classification and blood routine of the subjects, respiratory system, digestive system, urinary system and mood all improved to some extent, which proved that drinking Wang Laoji herbal tea for a long time had a positive effect on health. " Although specific data have been released, Wang Laoji’s function of "prolonging life" has not been widely recognized because the report only involves experiments related to rats.

　　As for the "life extension" storm, Wang Laoji responded on the evening of December 6 that the conclusion of life extension was obtained from 576 rat samples, and the relevant statements were basically consistent with the information released in 2016.

　　Survival rate is mainly used for safety verification.

　　On December 6, Huang Junming, director of the Institute of Health Toxicology of Guangdong Provincial Center for Disease Control and Prevention, admitted to the reporter of Beiqing Daily that the center had indeed participated in related 863 projects. "This project exists, and the project number is 2010aa023001. However, we only participated in the experiments of early rats and were not responsible for the human experiments. "

　　According to Huang Junming, the members of this 863 research group include several universities, several research institutions and many enterprises. At that time, it was a huge project, herbal tea was only one of the sub-items, and our team was responsible for part of the work.

　　He recalled the operation of the project to the reporter of Beiqing Daily. At that time, there were three herbal teas participating in the experiment. Among them, Jiaduobao and Wang Laoji’s experiments involved the survival rate of rats, both in red cans and green boxes. Another brand product does not involve this indicator. "Our animal experiments mainly focus on the safety of herbal tea, and the final survival rate of rats is an index to investigate the results." Huang Jun Ming said, "The experiments in which Jiaduobao and Wang Laoji participated were successful, and the animal survival rate reached the previous experimental design. The fact of the experiment was that the rats who used herbal tea lived longer than those who did not."

　　Huang Junming repeatedly stressed: "The survival rate is only the result of our experiment, not the purpose of the experiment. As to whether Wang Laoji has the function of prolonging life, I can’t give a conclusion. As for how the company publicizes, it is beyond our control. "

　　When asked about the funding of this scientific research project, Huang Junming said that all scientific research projects are supported by funds. In addition to the higher-level funding, all units that undertake the project also have inputs. "At that time, Wang Laoji, Jiaduobao and another herbal tea company provided strong support in terms of samples, materials, production, processing and experiments, which ensured the smooth progress of the project."

　　A staff member of the Guangdong Provincial Center for Disease Control and Prevention said that the research results released by Wang Laoji only mentioned about 10% of the experimental results, but did not provide specific experimental details and experimental data, and even the experimenters did not mention it. "The result is very vague and the words are unknown, so we are also verifying it further, but we are not responsible for this experimental result for the time being."

　　Expert: Herbal tea is not suitable for everyone.

　　Wang Fengzhong, deputy director of the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences, said that because rats and humans belong to different species, the conclusions obtained in rat experiments may not necessarily apply to humans.

　　Wang Fengzhong said that related efficacy tests often require a series of animal tests such as fruit flies, rats and monkeys, and finally human trials. Due to the complexity of human body structure, many ingredients that work on animals may have little effect on human body. "If we want to prolong human life by 10%, we need to prolong life by at least 30% in rat experiments."

　　Wang Fengzhong introduced that at present, there is no such thing as "prolonging life by 10%" in the related experiments of functional foods. "Now no one dares to say that it can improve human life span by 10%, and even drugs dare not claim to have such effects."

　　Wang Fengzhong said that herbal tea is not suitable for everyone to drink. "Every product has its optimal population, and it is impossible for a certain product to cure all diseases. Just as some people are allergic to eating eggs, herbal tea cannot be beneficial to everyone. "

　　Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, told the reporter of Beiqing Daily that to prove that Wang Laoji has a certificate of life extension, it is necessary to produce accurate research data. "The conclusion without data is unbelievable from my personal point of view", and there is no related research on whether it is vitamin drinks or energy drinks.

　　Fan Zhihong said that this kind of research on life extension needs to be followed for many years, and the sample is very large, and all kinds of mixed factors should be avoided, that is to say, other factors affecting life should be excluded to prove that only one factor has an impact.

　　Fan Zhihong said that she didn’t know much about the traditional Chinese medicine ingredients in the formula of Wang Laoji herbal tea, but as a high-sugar beverage, it was not suitable for everyone to drink. In addition, from the perspective of publicity, it is not appropriate to highlight the life-extending effect of products. Ordinary food cannot publicize its efficacy, even if herbal tea belongs to health care products, "prolonging life" is not among the efficacy of health care products.

　　The reporter of Beiqing Daily inquired from the website of china food and drug administration that the food and beverage branch of Guangzhou Wanglaoji Pharmaceutical Co., Ltd., the parent company of Wanglaoji Herbal Tea, registered its products as plant drinks, which means that Wanglaoji Herbal Tea is a beverage and not a health care product.

　　According to the relevant provisions of the Technical Specification for Inspection and Evaluation of Health Foods (2003 edition) issued and implemented by the Ministry of Health in 2003, health foods with health claims can declare 27 functions such as enhancing immunity, antioxidation, assisting in improving memory, relieving physical fatigue and losing weight, which does not include the function of prolonging life.

Passengers who have purchased tickets for stopped trains can apply for refund on the Internet within 30 days (including that day) from the ticket date, or return the tickets to the station with the original valid identity documents used at the time of ticket purchase (please give the vouchers to the station window staff if the reimbursement vouchers have been printed), and no handling fee is charged for the above.　 　

　　This newspaper (reporter Zhao Xin) went shopping, and I don’t know how many citizens paid attention to the songs played in the store. Yesterday, the Internet began to spread that "the sudden change of songs in shopping malls is a mysterious hint", reminding consumers that hot songs are "anti-thieves". Is there such a "hint"? Yesterday, reporters contacted many shopping malls in Wuhan, and some shopping malls said that this prevention mechanism does exist. Have you ever encountered such a "hint" when shopping?

　　"pay attention! The change from soothing songs to energetic songs in shopping malls is to remind people who are used to stealing admission. " Yesterday, netizen @ Oregon Seven Sisters said that she tried on shoes when she was shopping in the mall many years ago. The light music originally played turned into a strong song. The salesperson told me that there was a habitual thief entering the mall. After the security guard found it, he informed the studio to remind him. This blog post was forwarded by the majority of netizens, saying that they had encountered similar situations. Some netizens also expressed doubts, saying that the sudden change of genre may be just a coincidence.

　　Is there such a "secret code" in the mall? Do local shopping malls in Wuhan have their own reminder system? Yesterday, the reporter found out from Guoguang, World Trade Organization, China Merchants, Qunguang, Ikea Huiju and other large shopping malls that some shopping malls did implement this code law. According to the staff from Qunguang, they will use this method to remind employees that there are fixed tracks for different phenomena, but the song list is not convenient to publish. The gathering of Zhongshang Square and IKEA also indicates that there are similar early warning methods. "In fact, this is just a sudden emergency mechanism." According to the relevant person in charge of a shopping mall, the public security environment and security have improved, and it is difficult to use the song-changing code. If thieves appear, they will directly intercept them at the scene to create a safe shopping environment for the citizens.

The following article comes from Suzhou CDC, and the author is Suzhou CDC.

In the cold winter.

Infectious diseases such as influenza and mycoplasma pneumonia are high.

To this end, Suzhou CDC released

Guidelines for vaccination of respiratory infectious diseases in high incidence period

Let’s watch it together!

?

flu

Influenza is an acute respiratory infectious disease caused by influenza virus, which is highly contagious, mainly spread by droplets, but also indirectly through contact with contaminated hands and daily necessities. People are generally susceptible. After infection, they will gain a certain degree of immunity to the same subtype, but there is no cross-immunity between different subtypes, so people can get sick repeatedly because of different subtypes of infection.

Vaccination of influenza vaccine every year is the most effective means to prevent influenza. Because the composition of influenza vaccine will change due to the different epidemic dominant strains in that year, it is necessary to vaccinate influenza vaccine every year.

According to the types of influenza virus strains, influenza vaccines are currently divided into trivalent and tetravalent.

The strains covered by trivalent influenza vaccine this year are: influenza A H1N1, influenza A H3N2 and influenza B Victoria; The tetravalent influenza vaccine contains more strains of Yamagata influenza virus B than trivalent influenza vaccine.

At present, the influenza vaccine in Suzhou is a non-immunization program vaccine, which is vaccinated by residents voluntarily at their own expense.

Influenza vaccine immunization program:

1. Adult trivalent and tetravalent inactivated influenza virus vaccine, the target of vaccination is people aged 3 years and above, with one dose;

2. Children’s trivalent and tetravalent inactivated influenza virus vaccine, the vaccination target is children aged 6-35 months, and 1 or 2 doses are inoculated according to the vaccine instructions of different manufacturers;

3. Live attenuated trivalent influenza vaccine, targeted at children and adolescents aged 36 months to 17 years, with one dose.

Pneumococcal disease

Streptococcus pneumoniae (Spn) is the main pathogen causing pneumonia, meningitis, bacteremia and other serious diseases in children, and it is also the common cause of acute otitis media and sinusitis.

Pneumococcus is often temporarily colonized in human nasopharynx, and infants are the main hosts, which are generally transmitted by respiratory droplets or caused by colonized bacteria.

WHO lists pneumococcal diseases as diseases requiring "extremely high priority" for vaccine prevention. At present, the pneumococcal vaccines approved for marketing in China are divided into 13-valent pneumococcal polysaccharide conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPV23).

PCV13

At present, there are three kinds of PCV13 listed in China, all of which are suitable for infants and children aged 6-5 (before their 6th birthday). Specific vaccination procedures are as follows:

PPV23

PPV23 is used for people over 2 years old with increased risk of pneumococcal infection and pneumococcal diseases, especially but not limited to the following key populations:

① the elderly population;

② Individuals with chronic cardiovascular diseases (including congestive heart failure and cardiomyopathy), chronic lung diseases (including chronic obstructive pulmonary disease and emphysema) or diabetes;

③ Individuals suffering from alcoholism, chronic liver diseases (including cirrhosis) and cerebrospinal fluid leakage;

④ Functional or anatomical individuals without spleen;

⑤ People with impaired immune function (including HIV-infected people, leukemia, lymphoma, Hodgkin’s disease, multiple myeloma, common malignant tumors, patients with chronic renal failure or nephrotic syndrome), patients with immunosuppressive therapy (including corticosteroids) and patients with organ or bone marrow transplantation.

Usually, only one dose should be inoculated to the target. For those who need multiple cropping, they should be inoculated according to the instructions, and the interval of multiple cropping should be at least 5 years.

In order to implement the "531" action plan of Suzhou Healthy City, implement major infectious disease prevention and control projects, further reduce the incidence of pneumococcal pneumonia among the elderly in this city, and reduce the disease burden caused by the disease, Suzhou City has implemented free vaccination of 23-valent pneumococcal polysaccharide vaccine for the elderly over 65 years old in the city since April 2018. During the implementation of the project, every eligible elderly person can enjoy a free vaccination.

Mumps, measles and rubella

01

epidemic parotitis

Mumps is an acute respiratory infectious disease caused by mumps virus, which is more common in children and adolescents, but also in adults. It occurs in winter and spring, and it is easy to break out in schools, nurseries, kindergartens and other places where children are concentrated.

02

measles

Measles is caused by measles virus, which is highly contagious, and human beings are generally susceptible to measles virus. Patients are the only source of infection and spread from person to person through respiratory droplets.

03

rubella

Rubella is caused by rubella virus and is highly contagious. Rubella patients are the source of rubella infection and spread through respiratory droplets. Typical rubella has a pink mottled rash, which is easy to distinguish from measles with patchy dark red spots and papules. The mother suffers from rubella during pregnancy, and the virus can invade the fetus through the placenta, which may lead to fetal malformation, premature delivery, abortion and other dangers.

Vaccination with measles vaccine (MMR) is an effective means to prevent the above three infectious diseases.

Suzhou is currently carrying out the work of leak detection and replanting of vaccines containing measles components. Children aged 8-17 months who have not been vaccinated with measles vaccine, and children aged 18 months -18 years who have not been vaccinated with measles vaccine for 2 doses, all children who have no contraindications for vaccination with measles vaccine are the recipients.

In addition, in order to improve the level of protective antibodies against measles and rubella among teenagers, reduce the incidence of measles and rubella among the target population in adulthood, and reduce the risk of neonatal congenital rubella syndrome caused by rubella infection in women’s reproductive stage, Suzhou City has included the enhanced immunization program of measles and rubella vaccine for junior middle school students in local immunization plans, and all junior middle school students who are in good health and have no contraindications to measles and rubella vaccine can receive a dose of measles and rubella vaccine for free.

chickenpox

Chickenpox is a common infectious disease in children caused by varicella-zoster virus infection. Chickenpox patients are the only source of infection, mainly through respiratory droplets and direct contact.

The disease is highly contagious and people are generally susceptible to chickenpox. Persistent immunity can be obtained after illness, and it is rare to get chickenpox again, but herpes zoster can occur repeatedly. This disease can occur all year round, with the peak in winter and spring.

Vaccination program for varicella:

Vaccination with varicella vaccine is the most economical and effective means to control the spread of varicella.

Since January 1, 2023, Jiangsu Province has included live attenuated varicella vaccine in children’s immunization program, and school-age children can receive two doses of live attenuated varicella vaccine free of charge.

Immunization procedures are: the first dose for 12-18 months old, the second dose for 4-year-old children, and the interval between the two doses is not less than 3 months.

epidemic cerebrospinal meningitis

Epidemic cerebrospinal meningitis is purulent meningitis caused by meningococcus, which is a very dangerous acute respiratory infectious disease.

The high incidence season of epidemic cerebrospinal meningitis in China is in winter and spring. Man is the only host of meningococcus, which is spread by droplets or respiratory secretions. Carriers and patients are the main sources of infection. The population is generally susceptible, and the infection rate is the highest among children under 5 years old, especially infants from 6 months to 2 years old.

At present, there are five groups of meningococci causing human diseases: group A, group B, group C, group Y and group W135. The preventable groups of vaccines containing epidemic cerebrospinal meningitis in China are group A, group C, group Y and group W135.

Vaccination program for epidemic cerebrospinal meningitis:

According to the vaccination program of the national expanded immunization program, children aged 6 and 9 months were vaccinated with group A meningococcal polysaccharide vaccine, and A+C meningococcal polysaccharide vaccine was strengthened when they were 3 and 6 years old.

In addition, there are self-funded vaccines containing meningococcal components, including AC conjugate vaccine, AC-b combined vaccine of Haemophilus influenzae (AC-Hib combined vaccine) and ACYW135 group meningococcal polysaccharide vaccine.

Haemophilus influenzae type b

Haemophilus influenzae type B (Hib for short) can cause serious diseases in children, such as meningitis, pneumonia, septicemia, cellulitis, pericarditis and osteomyelitis. Hib can be colonized in human nasopharynx, and carriers are the main source of infection, mainly transmitted by droplets. More than 90% of cases of invasive Hib disease occur in children under 5 years old.

Hib immunization program:

In the Hib Vaccine Position Paper published by WHO, since serious Hib diseases mainly occur in children aged 4-18 months, they should be vaccinated as early as 6 weeks after birth.

Hib vaccine is a non-immunization program vaccine, and it is vaccinated according to the principle of voluntary, self-funded and informed consent.

At present, the vaccines containing Hib ingredients approved for marketing in China include: Hib conjugate vaccine, acellular DTP Hib conjugate vaccine (quadruple vaccine), adsorbed acellular DTP inactivated polio and Hib conjugate vaccine (quintuple vaccine), and AC meningococcal (conjugate) Hib conjugate vaccine (meningococcal AC-Hib conjugate vaccine).

(1) Hib conjugate vaccine

(1) Infants under 6 months old: from 2 months old or 3 months old, once every 1 month or 2 months, for 3 times in total. At the age of 18 months, one more booster immunization can be given.

(2) Infants aged 6-12 months: once every 1 month or 2 months, twice in total. At the age of 18 months, one more booster immunization can be given.

(3) Children aged 1-5: Only once.

(2) Quadruple vaccine

Three doses of basic immunization were given at the age of 3, 4 and 5 months; One dose of booster immunization was given at the age of 18-24 months.

(3) Five vaccines

Three doses of basic immunization were given at the age of 2, 3 and 4 months or 3, 4 and 5 months; One dose of booster immunization was given at the age of 18 months.

(4) meningococcal AC-Hib combined vaccine

(1) Vaccination begins at the age of 2-5 months, and a total of 3 doses are required, with an interval of 1 month for each dose;

(2) Vaccination begins at the age of 6-11 months, and a total of 2 doses are required, with an interval of 1 month for each dose;

(3) Vaccination is started at the age of 12-71 months, and only one dose is needed.

　　BEIJING, June 8 (Yang Yuqi) On the 7th, the 2019 national college entrance examination officially kicked off. On the first day of the college entrance examination, in addition to thousands of candidates, composition topics and examination rooms, parents’ "fancy sending exams" and love protection in various places have become the focus of public opinion. This afternoon, the college entrance examination in most parts of the country will end.

　　On June 7, outside the test center of Chengdu Shude Middle School, some parents put on cheongsam and held sunflowers to cheer for their children, which means "winning the flag" and "winning the championship in one fell swoop". Zhang wave photo

　　Parents "fancy to send exams"

　　— — Wearing cheongsam means winning the flag and taking sunflower means winning the championship in one fell swoop.

　　According to the information released by the Ministry of Education, the number of applicants for the national college entrance examination reached 10.31 million in 2019 (excluding the number of applicants for enrollment expansion in higher vocational colleges). This is an increase of 560,000 compared with last year. It is the second time that the number of applicants for the college entrance examination has exceeded 10 million after 10.2 million in 2009.

　　On the first day of the college entrance examination, in the test center attached to the Beijing Municipal People’s Congress, red became the main color among the parents who sent for the exam. Many dads specially selected red T-shirts, while mothers chose red cheongsam and red dresses.

　　"Wearing red clothes means getting off to a good start, and wearing cheongsam means winning the flag." A mother who sent the exam explained to the reporter.

　　In addition to paying attention to clothes, outside an examination room in Guiyang, many parents are holding sunflowers to take the exam. Parents said that this is to hope that their children will "win the championship in one fell swoop". Some parents made a special trip to prepare zongzi for the exam. One parent explained: "One is to eat zongzi for the Dragon Boat Festival, and the other is to add zongzi to the college entrance examination, that is, ‘ High school ’ Meaning ".

　　The essay topic attracts attention.

　　— — Patriotism, spirit of struggle and thinking about life are the key words.

　　On the first day of the college entrance examination in 2019, the Chinese composition of the college entrance examination, which has attracted much attention, has also become the focus of social attention. This year, there are 8 sets of national college entrance examination papers, including 3 sets of unified propositions from the examination center of the Ministry of Education and 5 sets of independent propositions from Beijing, Tianjin, Shanghai, Jiangsu and Zhejiang.

　　According to Xinhua News Agency, patriotism, fighting spirit and thinking about life are the key words of this year’s college entrance examination composition topic. The relevant person in charge of the Examination Center of the Ministry of Education said that 2019 marks the 70th anniversary of the founding of People’s Republic of China (PRC) and the 100th anniversary of the May 4th Movement. This year’s college entrance examination essay focuses on moral education, actively responds to the major themes of the times, and explores the profound connotation of moral education in the new era.

　　According to the introduction of "Weiyan Education", the new media of government affairs of the Ministry of Education, the national volume II composition test "Youth takes over the stick, and a strong country has me" provides five specific writing situations, requiring candidates to complete writing tasks in a specific identity and style in combination with a specific historical background; The national volume I composition "Love labor, start with me" requires candidates to "write a speech for our classmates".

　　"Weiyan Education" said that these test questions are set in real situations and the writing tasks are clear, which is convenient for candidates to put themselves in their shoes and think, and give full play to their writing level. The test questions require candidates to write in a specific applied style, thus releasing a strong signal: writing should be based on the needs of real life, emphasizing practical application and the integration of knowledge and practice.

　　In addition, Beijing volume "Resilience of Civilization" and Zhejiang volume composition "‘ Author ’ With ‘ Works ’ " As well as the essay "Harmony of Five Flavors, Coexistence and Coexistence" in Jiangsu, candidates are required to think in combination with real life and related times. The topic space is large and speculative, which is convenient for examining the thinking quality and language expression ability of candidates in many aspects.

　　Guarantee the college entrance examination

　　— — Social love, exam assistance and strength escort candidates.

　　In order to ensure the smooth progress of the college entrance examination, caring measures from relevant departments and all walks of life have also become the focus of media attention. On the eve of this year’s college entrance examination, on June 5th, the Ministry of Education asked local education departments to coordinate with relevant departments to further strengthen comprehensive protection in noise control, health and epidemic prevention, heatstroke prevention and cooling, and create a secure and comfortable examination environment for candidates.

　　This year’s college entrance examination has provided all-round safeguard measures for the smooth progress of the college entrance examination.

　　For example, on the morning of the 7th, outside the test center attached to the Beijing People’s Congress, the Love Delivery Service Station has specially prepared all kinds of first-aid medicines, drinking water, fans and other supplies to serve candidates and parents. There are also police, traffic assistants and urban management staff around the examination room to maintain order on the spot.

　　In Haikou, Hainan, all test sites are equipped with air conditioners for candidates, and the examination risk investigation and prevention and control are strengthened to cope with extreme weather such as high temperature, typhoon and thunderstorm that may occur during the college entrance examination.

　　In terms of traffic security, many regions have also made special arrangements. In Yantai, Shandong Province, the traffic police have carried out control management in the road sections where congestion may occur in the city to ensure that candidates arrive at the examination room smoothly; In Nanchang, Jiangxi Province, which is experiencing rainy weather, the urban management department has stepped up road inspections in areas and lots with dense test sites and more candidates coming and going. Once water waterlogging is found, it will take early warning and forced drainage measures.

　　Reproduction of "Routine News" in College Entrance Examination

　　— — On the way to the exam, candidates should be careful.

　　Every year in the college entrance examination, there are always some "sloppy candidates" who forget their ID cards, admission tickets or are late for the exam. These unexpected situations that occur every year during the college entrance examination are called "routine news of the college entrance examination" by some netizens.

　　On the first day of college entrance examination this year, similar "routine news of college entrance examination" reappeared in many places. For example, three candidates in Wuhan went to the wrong examination room this morning, and then asked the local police to send them to the correct test center; A Kunming examinee lost his admission ticket. Fortunately, this admission ticket was picked up by the local traffic police and delivered to the test center … …

　　According to media reports, before the exam on the morning of the 7th, a candidate in Yibin, Sichuan accidentally dropped his ID card into a roadside drain, and it was taken out after being dug by local firefighters. Fortunately, the candidate was not delayed to take the exam.

　　In response to these "unexpected situations" in the college entrance examination, many netizens commented that they should check all kinds of documents many times before going out, and important things should be kept in mind.

　　On June 7, the first day of the college entrance examination in 2019, heavy rainfall occurred in Rong ‘an County, located in the mountainous area of northern Guangxi. Candidates went to the examination room in the wind and rain to take the college entrance examination. Tan Kaixing photo

　　There is heavy rain in many places in the south. 　

　　— — Yellow rainstorm warning! Candidates in these areas should pay attention.

　　On the first day of the college entrance examination, some areas in the south of the Yangtze River and northeast China were hit by heavy rain. According to the weather bulletin issued by the Central Meteorological Observatory at 18: 00 on the 7th, during the day on the 7th, heavy rain fell in parts of northwestern Fujian, central Jiangxi, central and southeastern Hunan, and in addition, moderate rain, local heavy rain or heavy rain fell in parts of Xing ‘an League, Hulunbeier and central Shanxi in Inner Mongolia.

　　According to the latest weather forecast, the rainy weather in some parts of the south of the Yangtze River will continue on the 8th, so college entrance examination candidates and parents need special attention.

　　The Central Meteorological Observatory continued to issue a yellow rainstorm warning at 18: 00 on the 7th. It is estimated that there will be heavy rainstorms in parts of northern and southwestern Hunan, north-central and eastern Jiangxi, southern Zhejiang, western and northern Fujian, southern Chongqing, northern Guizhou, northwestern Guangxi, western Yunnan and southeastern Tibet from 20: 00 on June 7th to 20: 00 on June 8th.

　　Among them, there are heavy rains in northwestern Hunan, northwestern and eastern Jiangxi, and northwestern Fujian, accompanied by strong convective weather such as short-term heavy precipitation, thunderstorms or hail. The maximum hourly precipitation is 30 ~ 50 mm, and the local area can reach more than 60 mm.

　　In addition, the Central Meteorological Observatory continued to issue a blue warning of severe convective weather at 18: 00 on the 7 th: it is expected that there will be thunderstorms or hail weather in eastern Inner Mongolia, southwestern Heilongjiang, central and western Jilin, Liaoning, northeastern Hebei, northern Shandong and southeastern China from 20: 00 on June 7 to 20: 00 on June 8.

　　Corolla has a history of 50 years since it was listed in 1966, and has undergone 10 changes. From the first generation of 1.1L, it gradually upgraded to 1.2L, 1.3L, 1.4L, 1.5L, 1.6L, 1.8L, 2.0L and even 2.4L in the North American market.

　　As the latest domestic model, the 11th generation Corolla has four displacement options, 1.2T, 1.6L, 1.8L and 1.8L hybrid engines. Then, the maintenance cost of these four models in the later period must be the most concerned by users when buying a car. Is the turbine the most expensive to maintain? Dual-engine hybrid has the lowest fuel consumption? After reading the article, I believe you have your own decision. (Because the attention of 1.8L model is low, it is not discussed in this article.)

● Warranty/maintenance cycle

　　Corolla’s entire vehicle is guaranteed for 3 years or 100,000 kilometers (whichever comes first). In addition, the warranty period of Corolla Twin Engine is 8 years or 200,000 kilometers (whichever comes first). In addition, since 2014, the maintenance cycle of Corolla has been extended from 5,000 km to 10,000 km.

　　The maintenance cycle of naturally aspirated engine, hybrid engine and supercharged engine are all 10,000 kilometers. In actual maintenance, some 4S shops may recommend shortening the maintenance interval on the grounds of poor road conditions in China, but I think it is no problem to use fully synthetic 10,000 kilometers for maintenance once for general road conditions.

● Maintenance price

　　It is rumored that the maintenance price of supercharged models is much more expensive than that of naturally aspirated models. This is not wrong, but it is not rigorous. Because supercharged vehicles usually have higher requirements for engine oil, at least semi-synthetic or all-synthetic engine oil should be used. Naturally aspirated vehicles have lower requirements for engine oil, and mineral oil can meet normal driving needs. But if you use the same synthetic engine oil, the maintenance price is almost the same.

　　There is little difference in maintenance price among the three displacement models. The maintenance accessories of the 1.2T and twin-engine models are exactly the same (the oil consumption is slightly different, which can be ignored), and the 1.6L model is only different in the air filter, which is cheaper than the other two models in 32 yuan. Because the air filter element only needs to be replaced once every 40,000 kilometers within 60,000 kilometers, the total maintenance cost within 60,000 kilometers is only cheaper than that of supercharged and twin-engine models in 32 yuan.

　　There is another detail. Because of the kinetic energy recovery system, the dual-engine model will have the function of lightly stepping on the brakes when driving at low speed. Therefore, the frequency of disc replacement is longer than other models.

● Fuel consumption

　　According to the data of car home netizens’ word of mouth, the fuel consumption of the 1.2T model is.7.3L/100km, and the fuel consumption of 1.6L vehicle is8.1L/100km, the fuel consumption of twin-engine models is4.7L/100km (all comprehensive fuel consumption). It is worth mentioning that the motor operation of the twin engines can save a lot of fuel when driving under urban congested roads, while the fuel consumption is similar to that of ordinary gasoline vehicles when driving at high speed.

　　From the above data, the annual fuel cost difference between the 1.6L model with the highest fuel consumption and the twin-engine model with the lowest fuel consumption is about 4,000 yuan, and the 1.2T model is about 1000 yuan cheaper than the 1.6L model (calculated by driving 20,000 kilometers a year). The more kilometers you drive, the greater the fuel cost difference.

　　The higher the oil price, the more obvious the advantages of dual-engine. Before the problems of short battery life and difficult charging of most pure electric vehicles are solved, the hybrid electric vehicle is the best "returning weapon".

● Summary

　　Compared with the most concerned 1.2T GL (priced at 119,800 yuan) and the twin-engine 1.8L CVT Pioneer Edition (priced at 139,800 yuan), the twin-engine car is 20,000 yuan more expensive, and the configuration of engine anti-theft, head airbag, heat insulation glass,, and shift paddles is more fuel-efficient and quite cost-effective.

　　I believe that after reading the article, everyone has a steelyard in mind. If your mileage exceeds 20,000 kilometers a year and your budget is sufficient, then the double engine is undoubtedly the best choice, and the low fuel consumption in the later period will make you return to your original position quickly. As for how to choose 1.2T and 1.6L, different people have different opinions. The advantage of 1.6L engine is that it has a large number of vehicles, and the later maintenance is convenient and easy, while the advantage of 1.2T engine is fuel economy and lower emissions. However, small-displacement turbines are the current trend. If I were you, I would choose the latter, because compared with the 1.6L model, it is only 2,000 yuan more expensive, and I enjoy the updated technology and environmentally-friendly low-carbon life.

Wang Sihan, Wang Peiyuan and Feng Liangda studied plastic wrap.

[Yellow axis and white axis plastic wrap should be distinguished]

When summer comes, watermelon has become a weapon for many families to relieve summer heat. Many people may have had this experience: watermelon can’t be eaten, wrapped in plastic wrap and put in the refrigerator for the next meal. Have you ever noticed the color of the shaft core of the plastic wrap used at home? Feng Liangda from Beijing No.2 Experimental Primary School found that the core of plastic wrap at home was white; And the core of the plastic wrap used in the watermelon stall near home is yellow. What’s the difference between plastic wrap with different shaft core colors? Which plastic wrap is better? Feng Liangda and his friends Wang Peiyuan and Wang Sihan launched an investigation together.

Under the guidance of parents and teachers, the three people learned through reading the materials that the raw material of white core plastic wrap is polyethylene PE, and the raw material of yellow core plastic wrap is PVC. As early as 2009, China issued the national standard of "Plastic Self-adhesive cling film for food", which covered the types of PEPVC cling film, and mentioned that "PVC cling film is only suitable for packaging fresh food such as vegetables and fruits that are not directly imported".

Three people used the equipment of the school and Xicheng Science and Technology Museum to carry out the combustion experiment, which verified the difference of the two materials. It was found that the solution that absorbed the gas released by the combustion of the yellow shaft core was acidic, and after adding silver nitrate, the solution produced white precipitate, which indicated that the yellow shaft core plastic wrap contained chlorine. The solution that absorbed the gas released by the combustion of the white shaft core was neutral, and there was no precipitation after adding silver nitrate, indicating that it did not contain chlorine.

So, what is the actual use of different types of plastic wrap? The three people also chose 14 large supermarkets, 22 small supermarkets, 10 mobile stalls, 7 farmers’ markets and 27 families for investigation. The results showed that the utilization rate of white-axis plastic wrap in large supermarkets was 57.1%; In small supermarkets, mobile stalls and farmers’ markets, the utilization rate of white-axis plastic wrap is 0; 85.2% private families use white-axis plastic wrap.

At the same time, although most regular supermarkets can use plastic wrap correctly, the staff are not clear about the material specifications; Even among families with high qualified rate, only 59.3% of them know the requirements for proper use, and 40.7% know the material of plastic wrap. "It shows that many people don’t know what kind of plastic wrap to use, and many times they don’t notice that the merchants use yellow-core PVC plastic wrap for them."

To this end, the research team suggested that in the packaging of food plastic wrap, in addition to the material of plastic wrap, it is also necessary to indicate the application scope of plastic wrap, and at the same time, the temperature range of safe heating of different plastic wrap should be clarified to remind merchants and consumers to standardize their use. In addition, we should strengthen the inspection of food cling film for small supermarkets, farmers’ markets, fruit merchants and mobile food stalls, and formulate punishment measures for illegal use of cling film; At the same time, strengthen publicity, such as posting posters of plastic wrap at bus stops, subways, networks, supermarkets, shopping malls, etc., to publicize the differences in the use of plastic wrap, and promote the standardized production of plastic wrap through consumption supervision.

[Express envelopes cannot be "one size fits all"]

Li Xinyang, from the middle school affiliated to Beijing Normal University, is a "drama-chasing" expert. She always places an order online for any performance she wants to see. But every time she opens the express envelope, she will find that the big express envelope is a bit "overqualified" compared with the small performance notes.

After paying attention to this issue, Li Xinyang found that the phenomenon of "small content and big envelope" is not uncommon. In addition to her own performance tickets, when the credit card applied by her mother was delivered, it was also packed in a big express envelope. In fact, the waste of disposable products caused by express packaging has been paid attention to. According to public reports, in 2016, the number of materials used in express packaging in China was staggering-according to statistics, in 2016, about 3.2 billion woven bags, about 6.8 billion plastic bags, 3.7 billion packing boxes and 330 million rolls of adhesive tape were consumed … But in contrast, the unreasonable use of envelopes has not attracted the attention of society.

What is the current situation of using express envelopes over size? What are the reasons behind it? How to solve it? After communicating with the instructor, Li Xinyang decided to take this as his research topic.

Through the questionnaire survey, Li Xinyang found that 97.16% of the public had mailed the tickets by express mail, and 90.34% of them bought the tickets through the Internet. Express mail has become the first choice of the public. In addition, the use of express envelopes by the public is not limited to sending printed materials. In the process of using express envelopes, 59.09% of the public mailed documents, 55.11% of the public mailed invoices, 46.02% of the public mailed certificates, 39.77% of the public mailed books, 32.95% of the public mailed tickets for performances, 17.61% of the public mailed greeting cards, and 39.77% of them mailed cards.

The courier company mainly provides 324X229mm No.9 envelope; The actual measurement shows that the size of the general performance ticket is 80X200mm, and only the No.5 envelope of 220X110mm is needed. The size of the credit card is 54.0X85.6mm, and only the No.3 envelope of 176X125mm is needed. According to the survey, nearly 40% of the respondents think that the size of the express envelope is too large, and over 60% think that the size of the express envelope should be based on demand.

In the investigation of the mailer, Li Xinyang learned that if five different types of envelopes are required to be carried, most of the postal and courier parties said that they would be troubled by carrying trouble and increasing the load.

On the basis of investigation, Li Xinyang put forward his own suggestions. She believes that the State Postal Administration should issue technical specifications for the express delivery industry. For express delivery envelope manufacturers, they can design and produce express delivery envelopes with different patterns according to the different needs of the public while ensuring the basic specifications of express delivery envelopes. In addition, she suggested that courier companies should provide personalized services and prepare courier envelopes with reasonable sizes. For example, there are many printed materials such as documents mailed by enterprises, and envelope No.9 can be the main one; Prepare the No.5 express envelope suitable for the theater and ticketing business network. You can also increase the size of the pick-up in the courier company APP or WeChat smart applet, so that the courier can prepare the courier envelope with a convenient size in advance and reduce the burden on the courier.

At the same time, in her opinion, the cost of large envelopes and small envelopes should be different; If the public prepares their own envelopes, the mailing fee can be appropriately reduced. "I hope to attract more public attention to this phenomenon and work together to make due contributions to environmental protection."

[Restaurant self-service seasoning safety is worrying]

Liu Yifei from Beijing No.2 Experimental Primary School is a little gourmet, especially fond of rice noodles and barbecues. After eating too much, she began to find that in order to meet the different tastes of customers, such restaurants would equip their tables with self-help public seasonings such as Chili oil, soy sauce and vinegar. Once, after seeing the report that the hygienic condition of street stalls was worrying, she came up with the idea of investigating the self-service spices in restaurants.

After searching on the Internet, it is known that the microbial detection of single seasoning such as soy sauce and vinegar on the dining table is carried out according to the state standard of pre-packaging before unpacking; However, in the current National Standards for Food Safety, there is no hygienic evaluation standard for spicy spices and mixed seasonings such as pepper and salt and Chili sauce. After consulting experts from the Food and Drug Administration, Liu Yifei learned that for condiments on the table, the national regulations only clearly pointed out that self-service condiments could not detect pathogenic microorganisms, but more detailed microbial inspection standards were still lacking; At present, there is no corresponding operating standard for the sub-packaging of soy sauce vinegar.

So, is the seasoning easy to breed microorganisms? After consulting the experts in xuanwu hospital Bacteriology Room, she learned that the seasoning bottles in restaurants are frequently used, and if they are not cleaned and disinfected regularly, they will probably become "invisible killers" that endanger people’s health. Among them, there are three reasons that may lead to the pollution of spices: on the one hand, unclean packaging operation will lead to the pollution of spices at the source; On the other hand, the containers containing spices in restaurants are not clean, not cleaned and disinfected according to relevant regulations, and the sources of customers are complex, which leads to secondary pollution of spices; In addition, the self-service seasoning does not follow the preservation method stipulated by the manufacturer, and it is easy to cause the growth of pathogenic microorganisms in open containers, at room temperature and for a long time.

His own sampling experiment also confirmed the expert’s statement. Liu Yifei tested 24 seasonings from 8 restaurants: 8 sauces, the qualified rate of total colonies was 25%, and the qualified rate of Escherichia coli was 50%; Eight vinegar samples, the qualified rate of the total number of colonies was 25%, and the qualified rate of Escherichia coli was 50%. Intestinal pathogens were detected in one vinegar sample. Due to the lack of national hygiene standards, it is impossible to judge whether it belongs to the normal range, but mold was detected in 50% of spices, and intestinal pathogens were detected in one spice (Chili sauce).

In this regard, Liu Yifei suggested that relevant departments should further improve the scope of food microbial detection of seasonings, and include those that do not have hygienic standards at present, such as spicy spices and mixed seasonings, into the detection targets to supplement the standards; At the same time, the operating specifications, seasoning storage methods, container standardization and other aspects of the restaurant service personnel’s sub-packaging of spices into small containers will be included in the "Food Safety Operating Specifications for Catering Services", and supervision will be strengthened to promote the self-management and self-control of the catering service industry.
