　　(CCTV reporter Zhang Chunling Cao Yuzheng)

　　On August 31st, Hebei University of Science and Technology released the "Investigation and Processing Results of Han Chunyu Team’s Withdrawal Papers" (hereinafter referred to as "Investigation and Processing Results") in a low-key way, trying to end the question about whether Han Chunyu had made a fraud for more than two years with a conclusion of less than 600 words.

　　What is the conclusion of the Han Chunyu incident? This is still an "unsolved case" at present, and Hebei University of Science and Technology has not clearly determined whether Han Chunyu is "academic misconduct" in its conclusion. In contrast, another university, Wuhan University, directly thought that Li Hongliang "had no academic fraud" when it was reported to the Li Hongliang team of the university on January 29th. Nevertheless, the academic fraud in Li Hongliang is still controversial.

　　The Paper (www.thepaper.cn) found in the investigation that whether Han Chunyu was "academic misconduct" was not clearly determined by the school, but the related "termination or revocation of relevant scientific research projects, revocation of academic awards and honorary titles" was actually one of the treatments for those responsible for academic misconduct in accordance with Chapter V of the Measures for Preventing and Handling Academic Misconduct in Colleges and Universities.

　　The Paper tried to get detailed information about the investigation from Hebei University of Science and Technology, the subject of the investigation, but Hu Yongqi, member of the Standing Committee of the Party Committee of Hebei University of Science and Technology and director of the Academic Committee, and the secretariat of the Academic Committee refused to answer the phone many times. In addition, the official website of Hebei University of Science and Technology has completely cleared the list of members of the academic committee of the school, and the relevant web pages only keep the title without the list content.

　　In view of the fact that Han Chunyu’s retracted paper "NgAgo-gDNA-oriented Gene Editing Technology" in the top international academic journal "Nature Biotechnology" caused a great sensation in the hot field of gene editing, and hundreds of laboratories took time, effort and money to verify it under the circumstance that Han Chunyu repeatedly emphasized "repeatability". In fact, "Investigation and Processing Results" is no longer only related to the interests and reputation of Han Chunyu and the school itself.

　　"Personally, I think the purpose of the investigation is just to find a way to cope with the past. Experimental errors can be subjective and objective, but fraud is fraud, and there is no subjective and objective distinction." A professor of Zhejiang University whose research interests include the improvement and application of CRISPR gene editing technology said this in an interview with The Paper (www.thepaper.cn). This is also the general view of the current academic circles on the Han Chunyu incident.

　　In addition, a researcher who participated in the real name query in October and November, 2016 and jointly wrote the article "Questions about NgAgo" ("Questions about NgAgo") recently revealed to The Paper that the National Natural Science Foundation of China specially organized experts to hold a hearing, and Han Chunyu attended the hearing. However, this hearing was not widely publicized in academic circles. The Paper contacted relevant experts by email, but he didn’t get a reply.

　　At present, the handling of Han Chunyu has made the outside world feel that Han Chunyu himself has just returned to the state before the publication of the paper, "unscathed". Some insiders told The Paper, "If it is academic fraud, then this kind of treatment is obviously unreasonable. If it is not academic fraud, it is good news for Han Chunyu and the school, and there is no reason not to announce it."

　　The investigation process was not open, and the school refused to talk.

　　According to the Measures for Preventing and Handling Academic Misconduct in Colleges and Universities, colleges and universities are the main body of preventing and handling academic misconduct. According to the Regulations of Academic Committees in Colleges and Universities, colleges and universities should set up academic committees according to law, with the academic committees as the highest academic institutions in the school, and exercise the functions of decision-making, deliberation, evaluation and consultation on academic affairs as a whole.

　　Official website of Hebei University of Science and Technology shows that the Academic Committee of Hebei University of Science and Technology is the highest academic institution in the school. "Under the framework of the articles of association of the Academic Committee of the school, we will exercise the powers of decision-making, deliberation, evaluation and consultation of academic affairs in our school, stick to academic professional judgment and abide by academic ethics."

　　According to The Paper (www.thepaper.cn), the director of the Academic Committee of Hebei University of Science and Technology is Hu Yongqi, a member of the Standing Committee of the Party Committee of Hebei University. This position is nominated by the president and elected by all members. The academic committee of Hebei University of Science and Technology is appointed by the president.

　　According to the website of the Institute of Technology of the Independent College of Hebei University of Science and Technology, Hu Yongqi graduated from the Department of Chemical Engineering of Hebei Institute of Chemical Technology in July 1983. After graduation, he stayed as an ideological and political work counselor and later became a classroom teacher. In June 1988, he obtained a master’s degree in chemical engineering from Beijing Institute of Chemical Technology, and a doctor’s degree in chemical engineering from Tsinghua University in June 1998. In October 1998, he went to the Department of Energy Science and Engineering of Nagoya University to do postdoctoral research.

　　In 2002, Hu Yongqi entered Hebei University of Science and Technology, and served as Dean of the School of Chemistry and Pharmaceutical Engineering and Dean of the Graduate School of Hebei University of Science and Technology. In scientific research, Hu Yongqi’s main research field is catalytic reaction process and technology.

　　A source told The Paper that in addition to the establishment of an investigation team by the academic Committee of the school, "Hu Yongqi is also responsible for organizing third-party investigations." However, in the conclusion issued by the school, the number and composition of the investigation team of the academic Committee, the third party and other basic details that are usually announced in the processing results are currently unknown.

　　In an attempt to restore the investigation process, The Paper contacted Hu Yongqi several times on September 5, but the other party did not answer. Also refusing to answer is the contact information of the academic committee secretariat provided by official website of Hebei University of Science and Technology.

　　It is worth noting that when The Paper inquired about the list of members of the Academic Committee in official website, Hebei University of Science and Technology, the page under this heading did not exist, but was blank.

　　In addition, when comparing the Regulations of Academic Committee of Colleges and Universities (Order No.35 of the Ministry of Education of People’s Republic of China (PRC)) with the Articles of Association of Academic Committee of Hebei University of Science and Technology, The Paper noticed that in the chapter of operation system, the Articles of Association of Academic Committee of Hebei University of Science and Technology stipulates that "whenever the contents that need to be kept confidential are determined at the academic Committee meeting of the school, members must keep them confidential and implement and maintain the results of deliberation or evaluation of the academic Committee." However, there is no such provision in the Regulations of Academic Committees of Colleges and Universities.

　　At the same time, the operating system chapters of the above two documents all stipulate that "the decisions made by academic committees should be publicized and an objection period should be set. If there is any objection during the objection period, with the consent of more than 1/3 members, a plenary meeting may be held for reconsideration. The decision adopted after reconsideration is final. "

　　However, the decision made by Hebei University of Science and Technology on the Han Chunyu incident was obviously not made public in official website. According to the person in the school contacted by The Paper, "I have not seen any publicity on this matter in the school". In the Measures for Preventing and Handling Academic Misconduct in Colleges and Universities (Order No.40 of the Ministry of Education of People’s Republic of China (PRC)), it is also stipulated that if there is a clear whistleblower, the handling result must also be delivered to the whistleblower, and a 10-day objection or appeal period will be reserved.

　　Raw data required to be disclosed.

　　According to the Measures for Preventing and Handling Academic Misconduct in Colleges and Universities, the investigation team should form an investigation report on the basis of finding out the facts. The investigation report shall include the confirmation of the person responsible for academic misconduct, the investigation process, the fact finding and reasons, the investigation conclusion, etc.

　　At present, the "Investigation and Processing Results" given by Hebei University of Science and Technology, which is less than 600 words, obviously lacks many elements compared with the requirements of the above investigation report.

　　As can be seen from the published conclusions, the investigation team said that it had carefully checked "all the original experimental data" involved in the paper. In fact, these raw data have been emphasized by scientists who questioned NgAgo technology.

　　As early as July 21st, 2016, Gaetan Burgio, a geneticist at the Australian National University, posted a long article "My NgAgo Experience" on Twitter, asking Han Chunyu to disclose all raw data and experimental conditions.

　　On October 10th, 2016, 13 China biologists, including Professor Wei Wensheng of Peking University College of Life Sciences, jointly voiced in the media. They could not repeat the experimental results, and unanimously expressed their hope that Han Chunyu would disclose all the original data. Han Chunyu’s Hebei University of Science and Technology and other relevant units (such as the National Natural Science Foundation of China) started academic investigation.

　　However, Han Chunyu never released the original data, insisting at that time that "it will be used and will be responded through academic journals".

　　In addition to the original data, the "repeatability" that the outside world is most concerned about only refers to entrusting a third party to carry out repeated verification tests, and the results of verification tests are not clearly explained. The wording used in the conclusion is, "I think that the papers that have been withdrawn have no basis for re-publication, and no subjective fraud has been found by the Han Chunyu team".

　　So, what is "no longer has the basis for republication"? What is "subjective fraud"? There is no subjective fraud. What’s wrong with the team?

　　"The conclusion of the investigation did not explain at all which link, which step and when it was wrong. What Han said could be repeated before was what was repeated. These were not mentioned. This is not a survey." The aforementioned Zhejiang University professor bluntly said.

　　Another academic told The Paper that as a scientific research unit, the conclusion made by Hebei University of Science and Technology is "too imprecise". "You just say a conclusion that there is no subjective fraud, so the specious conclusion is very unscientific." Referring to the investigation and handling of similar international cases of academic fraud, the scientific approach is to describe the investigation process and make the final determination one by one according to the doubts of peers.

　　In fact, in addition to the conclusion that it is still foggy to the outside world, another version has been circulated inside the school before. A person from Hebei University of Science and Technology who is close to Han Chunyu’s team revealed to The Paper (www.thepaper.cn), "The conclusions passed between teachers before are not quite the same as those coming out now. It was said before that it could be made, but the efficiency was very low." The person also mentioned, "The investigation has already reached a conclusion, not recently."

　　However, the above statement cannot be confirmed by Hu Yongqi or the secretariat of the academic Committee at present.

　　Not only did this treatment make the outside world unconvinced, but also some practices or promises made by Han Chunyu and Hebei University of Science and Technology made the outside world wait for nothing again and again.

　　As for NgAgo’s work efficiency, when Han Chunyu gave a report to Zhejiang University, where Shen Xiao, the co-author of the paper, was located, he quipped, "In our laboratory, the success rate is over 90%, even if there is one plate of pollution in ten plates, because we have smog there.".

　　During the short period of less than 4 months from June 22, 2016 to October 14, 2016, the number of laboratories that Han Chunyu claimed to be able to successfully repeat its experiments was gradually reduced from 20 to 1. Even if there is only one laboratory, it has not been publicly claimed. Han Chunyu has refused to disclose it on the grounds that he does not want the other party to be harassed.

　　According to a report by Xinhuanet in August, 2016, Hebei University of Science and Technology said that in about one month’s time, Han Chunyu will take appropriate forms to publicly verify the results, and an authoritative third party will testify.

　　However, the school has not fulfilled its promise at that time.

　　The National Natural Science Foundation of China held a hearing and Han Chunyu attended.

　　In addition to the investigation organized by the academic committee of the school, Han Chunyu was supported by the National Natural Science Foundation for the project he applied for after the publication of the paper, and also participated in the hearing and defense of the National Natural Science Foundation.

　　A researcher who participated in the real-name query in October and November of 2016 and jointly wrote the article "Questions about NgAgo" ("Questions about NgAgo") recently told The Paper (www.thepaper.cn), "Before the National Natural Science Foundation of China specially organized experts to hold a hearing, Han Chunyu participated in the defense."

　　In September 2016, official website of the National Natural Science Foundation of China showed that the project "The Improvement and Application of NgAgo-gDNA Gene Editing Technology" with Han Chunyu as the project leader was approved for 1 million yuan, and the project started from January 2017 to December 2018.

　　Based on the fact that the above-mentioned project was approved after Han Chunyu’s paper, the authenticity of NgAgo-gDNA gene editing technology invented by him before is directly linked to whether this funding is established. The Measures for the Prevention and Handling of Academic Misconduct in Colleges and Universities clearly stipulates that the situation that should be considered as academic misconduct includes "providing false academic information in the process of reporting topics, achievements, awards and job evaluation".

　　In addition, it may be related to another grant involved in Han Chunyu’s retracted paper. It is mentioned in the paper "Thanks" that this paper was supported by the National Natural Science Foundation with the number of "31270950". The name of the project is "Evaluation of the Effect of Angiotensin Converting Enzyme on the Presentation of Exogenous Antigen in Cells and Its Physiological Significance", with an approved amount of 800,000 yuan, supported by Zhejiang University, and the starting and ending time is from January 2013 to December 2016. The project leader is Shen Xiao, the second author of the retracted paper and a researcher at Zhejiang University School of Medicine.

　　However, Shen Xiao once told the media, "I marked my fund, and there is no fund in Han Chunyu. But this research is basically self-raised by Han Chunyu through various channels, and my funds have not been invested in the experimental part. "

　　At present, The Paper contacted two experts who participated in the hearing by email, but no reply was received as of press time.

　　The aforementioned professor of Zhejiang University said, "If the National Natural Science Foundation of China holds such a hearing, it should be widely publicized, indicating that it is necessary to investigate the attitude of academic integrity."

　　According to the conclusion released by Hebei University of Science and Technology, relevant parties "terminated the research project undertaken by Han Chunyu’s team and recovered the research funds". However, it is not clear who the specific "relevant parties" refer to and how to recover the scientific research funds (part or used).

　　"Academic fraud" has not been determined, but the handling conforms to the relevant provisions of "Academic fraud"

　　In addition to the fact that the investigation results of withdrawing the paper itself make the outside world suspicious, Hebei University of Science and Technology’s handling results of Han Chunyu himself this time are also quite vague.

　　The result shows that after the publication of this paper, Han Chunyu’s personal housing, professional title and salary have not changed. During the investigation, Han Chunyu voluntarily requested to return the scientific research projects, performance awards, honorary titles, social posts, etc. Han Chunyu’s honorary title has been cancelled, the scientific research project undertaken by Han Chunyu’s team has been terminated, the research funds have been recovered, and the scientific research performance award won by Han Chunyu’s team has been recovered. Individual social posts are being handled according to legal procedures.

　　According to this result, after more than two years of ups and downs of being applauded and questioned, Han Chunyu himself just returned to the original point without being punished.

　　At the same time, if there is no subjective fraud, where is the basis for canceling the honorary title won by Han Chunyu and terminating scientific research projects? I’m afraid this needs further explanation from the school. What’s wrong with Han Chunyu’s team besides the "no subjective fraud"?

　　Compared with the fifth chapter of the Measures for Preventing and Handling Academic Misconduct in Colleges and Universities, "terminating or revoking relevant scientific research projects and revoking academic awards and honorary titles" is one of the treatments for those responsible for academic misconduct. The rest also includes informed criticism; Warning, demerit; Lowering the level of professional and technical posts and revoking professional and technical posts or administrative posts; Dismissal or dismissal; Other treatment measures stipulated by laws, regulations and rules.

　　If there is academic misconduct and it has a bad influence, it should be considered as serious. Treatment should be given to lower the level of professional and technical posts, revoke professional and technical posts or administrative posts; Expelled or dismissed.

　　In addition, Han Chunyu received 1 million yuan from the National Natural Science Foundation after the publication of the paper. In August 2016, the Development and Reform Commission of Hebei Province "agreed in principle" to the project of Hebei University of Science and Technology Gene Editing Technology Research Center with a total investment of 224 million yuan, and the funds were arranged by the provincial financial funds. This huge sum of money also makes the outside world think that the interests and reputations of Hebei University of Science and Technology and Han Chunyu are closely tied together.

　　On September 21, 2016, the project of purchasing imported instruments and equipment by the Gene Editing Technology Research Center of Hebei University of Science and Technology was opened in Shijiazhuang, with a budget of 19.58 million yuan.

　　At present, how does this most concerned huge sum of money end? Neither Hebei University of Science and Technology nor Hebei Provincial Development and Reform Commission announced a clear statement.

　　It is worth mentioning that this conclusion of Hebei University of Science and Technology not only makes the academic community full of doubts, but also feels disappointed. Some researchers said, "This survey results are contrary to the spirit of zero tolerance of academic integrity promulgated by the Ministry of Science and Technology. Now it is unclear why the counterfeiters can still continue to engage in academic work, and the academic community should really do it ‘ Zero tolerance ’ " .

　　More than one person is confused about the domestic academic environment. According to a report by WeChat WeChat official account Intellectuals a few days ago, Xu Chenyang, a mathematician born after 1980s who left Peking University to teach at Massachusetts Institute of Technology, talked about three major problems in domestic scientific and technological circles, including "academic fraud can’t be punished".

　　Xu Chenyang said, "Surprisingly, the suspected fraud has been exposed for a long time, and there has been no news to deal with it, let alone specific punishment measures."

　　"If ‘ Zero tolerance ’ Finally become ‘ Zero as ’ Or ‘ Inaction ’ It will make many people mistakenly think that our system does not punish or cannot punish academic fraud. If so, I think the impact is very bad. " Xu Chenyang mentioned.

　　At present, it seems that since the school announced the launch of the investigation in August 2017, the truth has not been one step closer to the public.

　　"A bottle contains 30 kinds of nutrients and can be full for 5 hours; Effective weight loss does not rebound; 6 flavors are changed for drinking. " Recently, an anchor sold a meal replacement milkshake called Smeal-NOTO series in the live broadcast room of the e-commerce platform. According to the seller, this meal replacement milkshake is a "body management tool that is popular all over the world". A bottle can provide 200g of protein for oysters, 1,000g of dietary fiber for vegetables, and 20 kinds of vitamins and minerals. The product introduction page also says: a bottle saves you an hour of exercise. On the e-commerce platform, this milkshake sells 39,000 bottles a month.

　　At present, meal replacement has become the new favorite of weight loss circle. meal replacement powder, meal replacement milkshake, meal replacement porridge and other products featuring "low calorie and strong satiety" emerge one after another. Then, can meal replacement products that make dieters rush to lose weight?

　　Eating meal replacement is equivalent to dieting in disguise.

　　"Weight loss with meal replacement is mainly achieved by reducing calorie and nutritional requirements. Improper use will affect health." Zhang Tian, a nutritionist in the Clinical Nutrition Department of Aviation General Hospital of China Medical University, told the Science and Technology Daily reporter that the meal replacement advertised in the market cannot completely replace normal meals. In order to maintain the basic metabolism and normal activities of the human body, a healthy adult woman needs about 1500— 1800 calories, men need 1800— 2,200 calories, safe weight loss is recommended to be reduced by 500— 600 calories, and to ensure that the nutrient ratio is reasonable. "But most meal replacement products do not meet the calorie and nutritional requirements for safe weight loss." Zhang Tian said.

　　Take the Smeal-NOTO series of meal replacement milkshakes in online celebrity as an example. The calorie of a bottle (75g) of meal replacement milkshakes with Ceylon milk tea flavor is 275 calories. The seller said, "One bottle can replace one meal, and three meals a day can be replaced. It is recommended to replace two meals a day, lunch and dinner. It is suggested that you should eat less oil and maintain 6-mdash when you eat a normal diet without meal replacement; 7 points full. "

　　According to the seller’s suggestion, drinking two bottles a day can only consume 550 calories. "This calorie is still very low. Even special obese people need to lose weight in such a low-calorie way under the guidance of a doctor. Eating meal replacement is equivalent to dieting in disguise, and the purpose of losing weight is achieved by increasing the difference between the required calories and the actual calorie intake. " Zhang Tian said that the extremely low-calorie weight loss method is not scientific and difficult to last for a long time. Once it stops, it is easy to cause weight rebound.

　　Long-term consumption is easy to cause malnutrition.

　　The nutrients needed by the human body need to meet a certain proportion. According to the recommendation of China Nutrition Society, lipids should account for 20% of the essential nutrients for human body & mdash; 30%； Protein accounts for 10%— 20%； Carbohydrate accounts for 50%— 65%。

　　As a mixture of various foods, can meal replacement be scientifically matched? The forms of meal replacement food include solid, semi-solid, liquid, etc., usually a mixture of various foods. "Meal replacement foods are often dominated by carbohydrates such as whole grains." Zhang Tian said that long-term consumption of meal replacement can easily lead to unbalanced nutrition and malnutrition.

　　Smeal-NOTO series meal replacement milkshakes claim that each bottle can provide 200 grams of protein (about 22 grams of protein) of raw oysters. However, the ingredient list shows that a 100g meal replacement milkshake only contains 8.6g of protein, so a bottle (75g) can only provide 6.45g of protein. "The protein that a normal human body needs every day is multiplied by 0.8&mdash per kilogram of body weight; 1.2。 For example, 50 kilograms of body weight, the daily protein content is 40-mdash; Between 60 grams. The protein content of this meal replacement is not as high as that of a pack of ordinary pure milk or an egg. No matter how many meals are replaced, the protein quality of each meal cannot meet the needs of the human body. " Zhang Tian said that consumers without nutrition knowledge background are easily confused by publicity.

　　"However, it should be noted that you can’t simply evaluate the quality of a food. For the human body, it is necessary to see whether the food structure can meet the needs of the human body as a whole. " Zhang Tian emphasized that it is ok to use meal replacement with other foods in the diet as long as the nutrition is balanced.

　　Dietary fiber makes people feel full.

　　In addition to low calories, satiety is another label that meal replacement is proud of.

　　Feeling full, in popular terms, means that although I haven’t eaten much, I still feel full. "Meal replacement is mainly based on coarse grains, konjac and other foods with more starch, which is characterized by high dietary fiber content. If you eat too much dietary fiber and you are not easy to get hungry, you can control your desire to eat. " Zhang Tian told the Science and Technology Daily reporter that the satiety of meal replacement is that dietary fiber is at work.

　　Professor Ai Hua, from the Nutrition Research Office of the Institute of Sports Medicine of the Third Hospital of Beijing Medical University, explained that dietary fiber in meal replacement has the function of water absorption and swelling, and it also has satiety effect without being absorbed and utilized by the human body. When dietary fiber is discharged through the intestine, it can also adhere to some fatty things, thus reducing energy intake.

　　Take konjac as an example, its rich glucomannan is very absorbent, so a few solids can form a lot of konjac gum, giving people a strong sense of fullness.

　　However, the dietary fiber provided by meal replacement may not be enough to produce satiety. Take the above-mentioned online celebrity meal replacement milkshake as an example. According to the taste composition table of Ceylon milk tea exposed by netizens, the content of dietary fiber in every 100g of goods is 1.8g, while that in 100g of vegetables generally contains about 3.5g.. Therefore, this bottle of meal replacement milkshake (75g) can’t provide the dietary fiber content of 1,000g vegetables as advertised.

　　In addition, in daily life, there are many coarse grains that can provide dietary fiber, such as corn, sweet potato, oats, brown rice and so on. In contrast, meal replacement food is likely to lose anti-inflammatory, anti-cancer, anti-oxidation and anti-aging substances contained in natural food during production and processing.

　　Zhang Tian also warned that excessive consumption of dietary fiber will affect the digestion and absorption of other foods, leading to unbalanced nutrition and affecting health. "We usually recommend that you eat coarse grains rich in dietary fiber, which should not exceed half of the normal diet. However, the dietary fiber in meal replacement food definitely exceeds this ratio, which is not conducive to the body’s absorption of other nutrients. "

　　For people with metabolic disorders, improper use of meal replacement food may cause health risks. In 2018, in order to lose weight, a citizen of Loudi City, Hunan Province ate only one meal replacement biscuit and some vegetables and fruits for two months, which eventually led to cardiac arrest due to malnutrition.

　　Earlier, the British "Daily Telegraph" published a study by Oxford University. The researchers found that meal replacement can indeed reduce people’s body fat, visceral fat and liver fat, but the myocardial fat has increased. This means that long-term intake of meal replacement has an impact on heart function. Researchers warn that for people with heart disease, dieting may worsen the condition and aggravate heart failure symptoms such as shortness of breath or arrhythmia.

　　Extended reading

　　Past lives of meal replacement.

　　In fact, the birth of meal replacement food has nothing to do with losing weight.

　　The original product of meal replacement series is beverage meal replacement, and its concept can be traced back to the research results of some early physiologists. In the 1940s, some researchers first identified the main nutrients needed for human survival during the period of strict food restriction. In the late 1950s, space flight required the development of highly compact liquid dietary substitutes, and an aqueous mixture was born.

　　At present, beverage meal replacement has occupied an important position in the meal replacement family and has become one of the tools to manage overweight and obesity.

　　On January 1st, 2020, the group standard "Meal Substitute Food" issued by China Nutrition Society was officially implemented. The standard pointed out that meal substitute food is a kind of energy-controlling food specially prepared to meet the nutritional needs of one or two meals for adults during weight control.

　　Zhang Tian said that under the guidance of doctors and professionals, obese and overeating people can choose some meal substitutes with comprehensive nutrition and strong satiety to replace some meals in the overall diet, which can help them lose weight. "But it is not recommended to follow the trend or blindly adopt a very low-calorie and unbalanced weight loss method. Such a low-calorie weight will definitely come down, but then the weight will definitely rebound. If you want to lose weight healthily and not rebound, you must respect science and rebuild a healthy lifestyle. If you are a healthy person with normal weight, you can eat well, and you don’t need to use meal replacement food to manage your weight. "

　　"A bottle of meal replacement milkshake with about 300 calories can be completely replaced by 50 grams of meat +250 grams of vegetables +2 corns /2 slices of bread /50 grams of cereal +5 grams of oil." Zhang Tian said, "People who have no time to cook and eat meal replacement can learn some Aauto Quicker meals. At least the milk, cereal and eggs in breakfast must be guaranteed. "

　　With the gradual expansion of the market scale of meal replacement food, the chaos in the industry is gradually breeding. Some exaggerate publicity to cater to consumers’ psychology of losing weight, some are produced in small workshops but pretend to be big brands, and some even have no products. In addition, the national health literacy is not high enough, which leads many people to fall into the trap of meal replacement.

　　Zhang Tian said that the dietary pattern can be balanced according to the Dietary Guidelines for China Residents, so as to achieve a balanced diet. "In fact, on the basis of a healthy diet, eat a few mouthfuls less every meal and reduce the time of sitting, and the weight will gradually decrease. Losing weight also requires patience. "

How long has it been since you watched a TV series at normal speed? /"Sweet honey is heavy as frost"

No more than 40 episodes, can not save the "water injection TV series."

I don’t know when domestic dramas became popular.

The end of the summer, in addition to the "school month", there are dramas chased in the summer vacation.

A Cui, a junior girl who is both a "rice circle girl" and a "drama master", this summer, in addition to her internship, she also chased three TV dramas that were highly discussed on the Internet.

She calculated that the three dramas add up to more than 150 episodes, which is longer than the two Empresses in the Palace’s combined.

If you carefully count the number of domestic dramas in recent years, you will find that it seems that you haven’t seen a short and pithy domestic drama for a long time, whether it is a big explosion or a silent broadcast.

There are also 42 episodes of "Dear, Dear", which has become a new slogan. /Figure "Dear, Dear"

I don’t know when domestic dramas became popular.

Giant system is not necessarily "high quality", but it is really long enough! It is not uncommon to take off in 50 or 60 episodes, even the length of 70 or 80 episodes. This huge number alone makes people lose the courage to follow the drama.

Biography of the Harem Zhen Huan, 76 episodes; Story of Yanxi Palace, 70 episodes; Sweet honey is as heavy as frost, 63 episodes; Ruyi’s Royal Love in the Palace has reached an astonishing 87 episodes …

Not long ago, the topic "# The General Administration plans to stipulate that the drama series should not exceed 40 episodes #" detonated the network. According to the report, the State Administration of Radio and Television is studying the policy of limiting the number of TV dramas and soliciting opinions from the industry. It is proposed to stipulate the upper limit of the number of episodes, and the upper limit is 40 episodes.

Can 40 episodes really prevent water flooding? /Caixin. com

Limiting the maximum number of episodes to 40 episodes can save domestic dramas that are flooded with water, but at least it can save domestic drama audiences who are forced to chase long dramas every day.

Contemporary human pursuit of drama daily life

Catch up with 100 episodes in one breath

Little friends who have chased domestic dramas know a "hidden rule", and now domestic dramas have a "fixed number of episodes".

There are no seventy or eighty episodes of costume drama, but forty or fifty episodes are the basic discs of modern drama. When did these series get longer and longer?

According to the "Recording of National TV Drama Production" published by the State Administration of Radio, Film and Television, the average number of episodes of domestic TV dramas has gradually increased since 2012, and in December 2015, it exceeded 40 episodes for the first time (40.95 episodes). From 2016 to 2018, the average number of episodes exceeded 40 frequently.

There are 74 episodes recorded and filmed in July 2019 alone. /SARFT website

Domestic dramas generally exceed 40 episodes, mainly after 2015.

The latest "Notice of the State Administration of Radio, Film and Television on the Filing and Publicity of National TV Series Shooting and Production in July 2019" updated the figures: In July 2019, there were 74 plays and 3,030 episodes of national TV series shooting and production.

74, 3030 episodes! A little calculation, the result is really amazing: the average number of episodes is 40.95, which has exceeded the envisaged upper limit of 40 episodes.

As the saying goes, "You have Zhang Liangji and I have a wall ladder". The "big production" of 70 or 80 episodes can’t slow down the speed of people’s drama pursuit, and thus a variety of new black technologies and skill guides for drama pursuit have been born.

One of the most familiar interface operations for drama girls.

It is only the first step for a qualified domestic drama audience to get used to using major video websites instead of TV sets. Xiaochao, a girl in the rice circle, summed up her three-step pursuit of drama-

The first step is to skip the beginning and end of the film; Step 2, start double-speed playback; The third step is to select only the selected single clip version you want to see.

Such an operation is as fierce as a tiger. Usually, a 45-minute episode can be finished in 15-20 minutes. Three steps down, chasing dozens of episodes of so easy in one day.

It is no exaggeration to say that double-speed playback has become the standard for young people to watch dramas nowadays. But when to play at double speed, when to watch at double speed, or even when to skip directly, there are many skills behind it.

If you can’t watch the TV series, just watch the barrage.

Ruyu, who claims to be a tenth-class fan of domestic dramas, often teaches others her "three axes necessary for double speed": memories, empty mirrors and slow motion, inner monologues or meaningless dialogues. As long as you encounter the above content, you can choose double-speed playback or even skip it directly without hesitation.

There are two kinds of memories, one is "Previously on Life", so skip it directly. The other is "flashback", such as the memories of the protagonist at the critical moment. Originally speaking, flashback can help the audience understand the plot, but most of the time, it is used by post-editing to piece together the plot, so it can also be skipped.

Not to mention an empty mirror. Lots of natural scenes, empty scenes without characters and slow-motion scenes without dialogue-unless you want to enjoy the background soundtrack at the moment, you’d better skip it.

I’m here to see people, not beautiful scenery. /"to the sky kingdom"

The last one is a bit difficult to judge, and it depends on personal preference. For example, in the TV series "Heroes of Sui and Tang Dynasties 5", such a typical meaningless dialogue, I believe it is difficult for someone to bear to watch it-

"How many associates are there here?"

"Here is a person."

"Eleven people?"

"Not eleven people, but one person."

"Twenty-one people? Say! Where are they hiding? "

"You heard wrong, actually alone."

"Seventy-one people, you think I’m stupid, such a small place!"

"Fool, you heard wrong again. Here is a person."

"ninety-one people!" "250, it’s one person."

"251 people, you really think I’m stupid!"

Excuse me, are you dizzy?

If it’s still too long, you can watch pictures and follow dramas in Weibo, Douban and WeChat official account, or open bilibili and choose xx minutes to watch the xx series.

The audience really saw a fire. /"Heroes of Sui and Tang Dynasties 5"

Why has the double-speed pursuit of drama become the daily pursuit of drama for contemporary young people? That’s because there is no triple or quadruple broadcast.

The latest news is: Now, all major video platforms have launched triple speed playback, triple speed! Is this speed rushing out of Asia and walking in the forefront of the world?

I just don’t know if you look at it this way. Are you watching movies or just watching a movie?

What are you doing so fast? It’s not a race against time. /"Lola Run"

Waist or continue life, see the real chapter by quality.

Film and television, a world-wide art, is of course deeply loved by people all over the world. After all, "couch potatoes" became popular in the United States as early as the 1960s.

How do foreigners chase dramas?

People who have seen American TV shows are familiar with the word "season". American TV shows are usually divided into seasons, and the number of episodes per season usually does not exceed 24.

The memories of countless people’s youth will always stay in the 12th season. /Figure "The Big Bang Theory" screenshot

The broadcast of American TV series is indeed characterized by "seasons". The dramas broadcast in autumn usually run from September to May of the following year, and the first half of each season is usually 10-13 episodes. After three months of broadcast, it will usher in the winter break (Hiatus).

During the winter break, TV executives can get ratings survey data and audience feedback, and they will use these indicators to evaluate the value of the new drama, whether to renew it or cut it? Speak entirely on the data that has been broadcast.

English dramas are even tougher. Although it is also a season, the number of episodes per season is about 3-9. Sherlock and Black Mirror, which are familiar to the audience in China, have only three episodes each season-obviously, unlike the long masterpieces of domestic dramas, overseas dramas pursue simplicity and liveliness.

Let’s look at Japan and South Korea next door.

After a lapse of seven years, the phenomenal drama Naoki Banze will finally usher in its second season next year. /"Naoki Nakazawa"

Japanese dramas, which are famous for their brevity, usually have 11-12 episodes. Even the most popular TV series will usually only launch an SP (Fanpian) with a length of about 50 minutes as a follow-up, and there are few sequels, "Never bow to the length". Korean dramas are slightly longer than Japanese dramas, and the total number of episodes of a single drama is usually around 20 episodes.

As we all know, Korean dramas had a period called "foot-binding cloth". For example, many childhood memories of the post-80s and post-90s "Dae Jang Geum" were as long as 54 episodes, and the duration of each episode was actually one hour.

In terms of broadcast mode and the length of episodes, there is no absolute difference between good and bad, not to mention that applying the production mode of overseas dramas to China will definitely have a good broadcast effect.

The longest-lived American TV series "Our Days" even has more than 10,000 episodes, and it is still not over. /"Our Days"

The most important and only responsibility of a TV series is to tell the story well.

In order to control the quality, overseas dramas are usually broadcast while shooting. Whether there is a next season or even an episode depends on the quality. It may be halved at any time, and it can also be a long-lived drama.

The classic American drama Lie to Me also stopped for three seasons because of quality problems. "Don’t Lie to me" solved the case through the eye-catching micro-expression polygraph method, and its novel setting attracted people’s attention at home and abroad, which once set a brilliant record in psychological drama. Up to now, there are many traces of paying tribute to it in film and television works at home and abroad.

However, after entering the third season, the ratings of "Don’t Lie to me" continued to be low, and received comments such as "lost freshness". In the end, it was mercilessly cut down by the TV station on the grounds of "audience aesthetic fatigue"-you know, Fox TV, which belongs to this series, is a character who is so determined that he can not hesitate to cut his back even the "entry-level drama" Prison Break.

The most classic "mind-reading detective" /"Don’t lie to me"

It can be seen that the quality of the series is not directly related to the length, and the length is only the most basic indicator.

In the final analysis, a 40-episode "water-injected TV series", even if compressed into 20 episodes, should be filled with water.

Some plays have too many episodes.

Some plays are 400 episodes.

If it is true, a good drama is not afraid of length, and 80 episodes of "Legend of Wulin" are not too tired to watch every day.

The top ten domestic dramas in Douban are many excellent works with more than 40 episodes of word-of-mouth and length. 46 episodes of Ming Dynasty 1566, 59 episodes of Towards the Republic and 80 episodes of Legend of Wulin are among the top five masterpieces.

I even want to watch 800 episodes. /"Wulin Biography"

The problem of "water injection TV series" is not "length", but "water"

However, why is it "water injection", which has become an unavoidable disease of the times in domestic dramas?

The root of this problem lies in that "episode" is not only the time node of TV drama creation, but also the basic unit of cost accounting and trading exchange: the more episodes a TV drama with a fixed cost can finally be edited, the more the cost is diluted, and the higher the income of the producer will naturally be.

This has also led to an endless stream of ways of "water injection" in film and television dramas.

From the simplest and rudest adding useless dialogues and useless scenes, repeating flashbacks, to adding supporting characters and over-rendering subplots, injecting water from the source of the script, and then inserting frequent oral advertisements, using clips to forcibly lengthen the duration, the water injection of film and television dramas has penetrated into all levels of editing, content creation and income return.

Previously, it took up a third of the length. /"Do you know if it should be green, fat and thin?"

In 2017, "Ode to Joy 2", although the ratings were good, was vomited by many viewers. Some viewers counted down and found that the producers stuffed as many as 51 brands in the play! Others spit out: the drama constantly pieced together the number of episodes with unnecessary plots such as music, characters’ memories and quarrels, and the whole drama was expanded to 55 episodes.

Ode to Joy 2 is not a case. Sun Li’s "The Full Moon Blossoms That Year" showed 50 episodes in the shooting and the previous press release, but it was 74 episodes in the final broadcast, which was a full "note" of 24 episodes.

For film and television dramas, the increase or decrease of the number of episodes may change the narrative way of the whole drama. If the drama is so bad, the masterpiece can’t escape the suspicion of water injection.

As an anti-corruption drama, the phenomenal work "in the name of people" triggered a ratings frenzy. However, the screenwriter admitted that for the sake of commercial benefits, the content of the original 40 episodes was finally "watered" by 15 episodes and written into 55 episodes.

A really good drama even dares to take a "waist cut" to shame itself. /"Kua Times"

The length of a long drama is to make it more handsome and atmospheric, not to facilitate "water injection". Hong Kong TV series, which is good at shooting long dramas, is a good example. Taking TVB as an example, it has produced 107 episodes of Genesis, 65 episodes of Men in Heaven and Earth, and 62 episodes of Passion in Heaven and Earth. Although the length of these plays is long, they all achieve high plot density, large amount of information and exciting.

2017 is the 50th anniversary of the establishment of TVB, and the drama "Kuadai" was the heavyweight drama of that year. At the press conference of Kua Times, starring Bobby Au—Yeung mentioned that the first boast of the play was that it was 50 episodes long.

The "length" of the drama series is not the original sin. Fans, no one wants to catch up with a long series full of water at double or triple speed. What they really want is to catch up with any good drama worth thinking easily without any double speed-it’s really not a big problem if it doesn’t grow long.

　　[New Journey of Strengthening the Country with Talents]

　　The spring is chilly, and the black land on both sides of the road in the hinterland of Sanjiang Plain in Heilongjiang Province is still covered with snow as far as the eye can see. Beidahuang Agricultural Reclamation Group Co., Ltd. (formerly known as "Heilongjiang Agricultural Reclamation Bureau") is located in laboratories all over the country, but it is already in full swing and full of vitality.

　　In the laboratory of Jiangchuan Branch of Kenfeng Seed Industry of Beidahuang Group, technicians are conducting a sampling germination test of rice seeds to ensure that growers can "safely plant" during spring ploughing. In Qixing Agricultural Technology Extension Center, the post-doctoral innovation practice base of Heilongjiang Province has just settled here, which will provide more talent support and scientific research motivation for increasing grain production and income.

　　In September, 2018, General Secretary of the Supreme Leader pointed out that the modernization of China cannot be separated from agricultural modernization, and the key to agricultural modernization lies in science and technology and talents. It is necessary to put the development of agricultural science and technology in a more prominent position, vigorously promote agricultural mechanization and intelligence, and insert the wings of science and technology into agricultural modernization. On September 28th of the same year, General Secretary of the Supreme Leader, when presiding over the symposium on further promoting the revitalization of Northeast China, pointed out that various measures should be taken to create the conditions for keeping people in mind, so that all kinds of talents can feel at ease, settle down and work in peace.

　　Over the years, Beidahuang Group has kept in mind the entrustment, made every effort to create a talent environment of "keeping people in mind", cultivated a high-level agricultural science and technology talent team, took root in Beidahuang’s innovation and entrepreneurship, and helped increase grain production and income. In 2022, the grain output of the Great Northern Wilderness reached "19 consecutive harvests", with a total grain output of 45.13 billion Jin, making the national grain safety ballast stone more stable.

　　1. Make every effort to break through the "neck-stuck" technology of provenance.

　　"You must plant this year ‘ Longken 2021’ Rice, the effect is very good. Last year, I had a bumper harvest after trial planting, with an average yield of more than 1,300 kilograms per mu. " At present, it is the season of preparing for farming, and Zhang Jinghui, a big planter in Qixing Farm, will recommend it to everyone.

　　In Nanfan Base of Kenfeng Seed Industry, Sanya City, Hainan Province, 4,000 kilometers away, Xu Xide, the chief rice breeding expert, wore rain boots, camouflage clothes and a big straw hat to observe the growth of rice with the research team in the scorching sun. "Conventional breeding of a new variety takes about 10 to 12 years from hybridization to test to variety approval. Southern breeding can speed up breeding and shorten breeding time." Xu Xide took off his straw hat and wiped a handful of bean-sized sweat on his forehead.

　　Seed is the "chip" of agriculture. In order to solve the technical problem of "sticking the neck" of provenance, Kenfeng Seed Industry of Beidahuang increased investment in scientific research, built a high-level R&D talent team and introduced high-level scientific research personnel through various channels. In 2013, Xu Xide joined Kenfeng Seed Industry to form a rice breeding innovation team.

　　"Here, we don’t talk about heroes by the number of papers, but by the achievements of scientific research and innovation. We put all our energy into scientific research, relying on the rich germplasm resources bank of enterprises and modern breeding laboratories to combine conventional breeding with biological breeding, with remarkable results. At present, the team can approve 10 to 15 varieties a year." Rooted in the land of three rivers, in the past 10 years, Xu Xide led the scientific research team to cultivate more than 20 high-quality rice varieties.

　　In order to encourage researchers to industrialize scientific research achievements, Kenfeng Seed Industry will give certain rewards to researchers according to the transformation amount of scientific research achievements and variety sales. This incentive policy enables "Longken 2021" to be quickly transformed into "Kenchuanxiang" brand.

　　"Ken is made up of roots and soil, Sichuan represents water, and incense is made up of grain and sun, which means the vast Sanjiang Plain at the foot of Wanda Mountain in the south of Xiaoxing ‘an Mountains. The rivers are vertical and horizontal, and the soil is fertile, which is fertile ground for the growth of high-quality rice." From the design of brand name, it shows Xu Xide’s intention and love. "In the future, we will ‘ Kenchuanxiang ’ It has become the core product of high-quality rice in the Great Northern Wilderness Group, which has promoted the industrialization of rice in the central and eastern parts of Heilongjiang Province and made the rice in the Great Northern Wilderness float across the country and even the world. "

　　Xu Xide has been engaged in rice breeding for 35 years since he joined the work in 1988. "A grain of rice not only provides life energy for human beings, but also is the basis for breeding the next generation. In the future, we will cultivate more high-yield and high-quality varieties, so that China rice bowls can contain more China grain. " Xu Xide said that year after year, seeing the seeds he cultivated flourish in the fields, his heart is full of vitality and strength.

　　2.“‘ Tukela ’ It’s full of high technology. "

　　In the Soil Laboratory of Sanjiang National Agricultural Science and Technology Park in Beidahuang, Han Bangdong, the head of the fertilizer testing project, is making a "soil testing formula fertilization card" for growers: "After the autumn harvest, we collect black soil samples from different plots to test and analyze the organic matter content. Not only can accurate fertilization be achieved, but also soil hardening caused by excessive fertilization can be avoided, thus protecting black land. "

　　Han Bangdong, born in 1994, can be regarded as "three generations of cultivation". Seeing the hard work of grandfather and father, Han Bangdong was determined to learn advanced agricultural technology from an early age to make farming less hard. He volunteered for the college entrance examination, and he filled in the agronomy major.

　　Soil testing, formula fertilization, variable fertilization, and non-stirring technology for drought leveling & HELIP; … Han Bangdong has worked in the construction of Sanjiang National Agricultural Science and Technology Park in Beidahuang for 6 years, and participated in more than ten scientific research experiments and popularization. "Don’t underestimate farming, now this ‘ Tukela ’ The school is full of high technology. " He said.

　　Qixing Farm of Beidahuang Group attaches great importance to the reserve of scientific research talents and team building, builds Sanjiang National Agricultural Science and Technology Park on the basis of Beidahuang, selects outstanding scientific and technological talents, makes job planning for young scientific researchers, and realizes the best use of talents. Over the past ten years, the park has completed more than 750 scientific research projects, introduced more than 800 new varieties, popularized 29 practical new technologies such as leaf age diagnosis, lateral deep fertilization and blanket seedling raising, and trained more than 50,000 farmers.

　　The park is not only a place to promote agricultural science and technology research and development, but also a reservoir for the growth of scientific and technological talents. "Park and ‘ Green super rice ’ Academician Workstation, China Agricultural University, Northeast Agricultural University and other research institutes have cooperated in joint research, which has built a very good platform for young researchers to participate in major project research and development. " Zhang Shaobo, the person in charge of the park, is also a native of the Great Northern Wilderness. "The average age of the team is only 33 years old. In recent years, new people have been joining in, and everyone is working hard, full of energy and making rapid progress."

　　"Inheriting the spirit of the Great Northern Wilderness and continuing to struggle, I hope that through the efforts of our generation, children can see an intelligent and modern Great Northern Wilderness." Han Bangdong often thinks like this.

　　3. The vast world makes talent learning useful.

　　A year’s plan starts with spring. Liao Yongxia, deputy director of agricultural development department and director of agricultural science and technology service center of Daxijiang Farm Co., Ltd. of Beidahuang Group, is busy planning this year’s scientific research project these days.

　　"There are more than ten items such as the renewal of planting varieties, the prevention and control of pests and diseases, and the optimization of fertilization technology in low-yield fields, mainly to solve the problems encountered in agricultural production last year." Liao Yongxia said.

　　"Yongxia, this is a good opportunity to stay in Beijing. Not only is it well paid, but it can also solve the Beijing hukou." When she graduated from college, her tutor felt sorry for Liao Yongxia when she learned that she had given up a Beijing enterprise she recommended and chose to work in a grass-roots farm in Beidahuang.

　　"The Great Northern Wilderness, as the vanguard of agricultural modernization in China, represents the direction of agricultural development in China, where the vast world can give me a stage to display what I have learned." This is Liao Yongxia’s prudent decision.

　　When he first arrived at the Agricultural Department of the Farm, Liao Yongxia was sent to the Science and Technology Park to participate in scientific research and experiments, and was responsible for insect monitoring. He got up at 5 o’clock every morning and went to the field to observe and record the number of adults. The dew in the morning soaked the pants, and the hot sun at noon made people sweat.

　　It’s nothing to suffer a little, but I’m most afraid of being distrusted by growers when doing technology promotion. "Is it possible to have fewer seedlings and higher yields?" When Liao Yongxia first began to promote the technology of sowing and density reduction on farms, growers questioned: "It’s okay for you college students to do research in the laboratory, but we have decades of experience in farming."

　　"speak with data and output." Liao Yongxia and the research team concentrated on the comparative experiment of planting density, and compared the output data before and after the application of technology to farmers, which won everyone’s recognition: "You can plant it in the future."

　　Engaged in agricultural science and technology for more than ten years, Liao Yongxia has collected more than 10,000 pictures of pests and diseases and crop growth, accumulated more than 20 agricultural diaries, and led scientific and technological teams to carry out more than 50 key scientific and technological research projects. In 2022, the output of the three main crops of soybean, corn and sorghum in Daxijiang Farm all set a record in the field.

　　"In recent years, farms have seized the ‘ Niubi ’ Strengthen the construction of agricultural technicians, set up professional teams, recruit college graduates to enrich scientific research strength, purchase advanced experimental equipment, improve office conditions, and let us invest in scientific research experiments and technology promotion with more peace of mind. " Liao Yongxia said, "No, two college students we recruited from Bayi Agricultural University are studying for master’s degree. The vast world of the Great Northern Wilderness has witnessed my growth, and I believe they will certainly make a difference here. "

Organization Department: General Administration of Quality Supervision, Inspection and Quarantine.
Spot check scope: 73 products produced by 59 enterprises in 9 provinces and cities including Beijing, Tianjin, Hebei, Jiangsu, Hubei, Guangdong, Zhejiang, Shanghai and Fujian.
Spot check time: the third quarter of 2006
General situation of spot check: the qualified rate of product sampling is 78.1%, and 14 kinds of national inspection-free products produced by 9 enterprises are all qualified.
Main problems: microbial indicators and pH value exceeded the standard; Identification and labeling are not standardized.

Sanitary napkins should be stored in a dry and sterile environment and have a certain expiration date. If the sanitary towel is wet or stored for a long time, it will deteriorate and pollute even if it is not opened.
Generally, sanitary napkins are made of non-woven fabrics and are made of fiber materials. After being wetted, the materials deteriorate and bacteria are easy to invade and multiply. Sanitary napkins are sterilized by high-temperature disinfection. After all, the effective period of one-time disinfection and sterilization is limited, and there is no guarantee of sterility beyond the time limit. Therefore, when using sanitary napkins, we should pay attention to the expiration date, and don’t buy too much at one time, which is not suitable for families to hide for a long time.
The unpacked sanitary napkins should be placed in a dry, clean and sterile environment, and should not be used after being wet and expired.

BG hint

▲ It is best to wash your hands before use, and try not to touch the surface of sanitary napkins with your hands to avoid secondary pollution. In addition, when using sanitary napkins, they should be replaced in time.

Expert purchase advice

□ Bouwing Lo, Deputy Director of National Paper Quality Inspection Center and Senior Engineer.

■ Look at the product identification. The sanitary napkin packaging should have information such as hygiene license number, production date, shelf life or validity period, standard number, manufacturer’s name and address. And try to choose products produced recently.
■ Choose brand-name products. The first choice is brand-name products produced by well-known enterprises with high market share in large shopping malls and supermarkets.
■ Pay attention to your own feelings. At present, there are many kinds of sanitary napkins, including cotton surface, mesh surface, fragrant sanitary napkins and medicinal sanitary napkins. You should choose the most suitable sanitary napkin according to your actual feelings.
■ See that the sealing of each outer package and independent small package of the package should be smooth and free from air leakage; A good sanitary towel should have a clean surface, uniform thickness and intact sealing. In addition, from the point of hand feeling, a good sanitary towel is made of fluff pulp, which is absorbent and fluffy, so it is light and soft. Sanitary napkins mixed with other pulp and scraps are heavy and hard.
■ According to the physiological stage, the menstrual period of general women can be divided into three stages, and different types of sanitary napkins can be selected according to these three stages. When the menstrual flow is large, we need to use wing protection during the day and night safety at night; Usually you can use the standard type; Ultra-thin or pads can be used before and after menstruation. On the one hand, this collocation choice is for safety and comfort, on the other hand, it is also for saving menstrual expenses.
■ It is not appropriate to buy large packaged products. Under normal circumstances, it is difficult to ensure that a whole package of sanitary napkins can be used up every time. Especially, office women often need to carry one or two tablets with them, and once the whole package of sanitary napkins is opened, it is easy to cause pollution. Therefore, from a health point of view, it is advisable to buy sanitary napkins in independent packages. If you want to consider economic factors, you can buy sanitary napkins without independent packaging, but with fewer tablets per package.

　　　　Mayday’s new album "Poetry after Puberty" recently released a brand-new title song "You are not really happy" after the inspiring Taiwanese strong-hearted song "Early Days". Known as "the most tearful lyric song of the year", the monster named "the first melancholy niche in our group" was recommended by Mayday as the leading actor to perform a difficult inner drama, playing a street performer who lives by telling jokes and making passers-by laugh at the cost of "50 yuan a piece" every day? Relieve your depression, but you don’t have enough for others? No one can tell the inner difficulties, but in the face of the external disturbances, we still have to smile.

　　The story shows that the current world is "unhappy"

　　　　Directed by director Chen Yuxun, you are not really happy, MV, in order to fully interpret the key lyrics of "The world laughed, so you laughed together in groups", the director played his best signature style of "laughing till tears", telling the story of young people starring monsters, making a living by telling jokes in the street, and it is his job to pass on happiness to everyone who needs it. He hopes to repair every sadness through jokes. How long has it been since you smiled happily? How long has it been since "real happiness"? Although it seems that I can bring happiness to everyone, I can’t do anything about my terminally ill girlfriend, and I can’t bring her a little happiness. I can only smile day after day. The director condensed the "unhappiness" hanging over the world with such a story of "listening to the monster telling jokes sadly", and also fully tested the multi-level acting skills of the head of the monster, which was laughed by the other four members of Mayday as the most difficult inner drama since the film was released.

　　　　The director also specially invited Zhou Caishi, the heroine of the idol drama "basketball fire", to challenge the inner drama with the monster. She filmed the MV of "Perfume" for Mayday before her debut. As soon as she heard that it was Mayday’s invitation, she did not say that she would cancel all the notices without compensation and resume her career with Mayday.

　　Member monsters turned into "Taiwanese version of Tony Leung Chiu Wai"

　　　　After the completion of the MV, the monster’s natural and introverted melancholy temperament was praised by director Chen Yuxun as "Taiwan Tony Leung Chiu Wai", and he said that the touching story of "You are not really happy" could actually be extended into a movie, and he also encouraged the monster to try to be an actor and develop towards "singing amphibious". As soon as the monster heard the director’s praise, he immediately retreated three steps shyly and shouted, "Wow, I dare not!" " The staff on the side also joked: Next time, we should break through the bottom line and challenge the ultra-bold bed play in Tony Leung Chiu Wai’s Lust, Caution. The monster quickly refused to finish laughing and said, "The romantic literary film is OK, but I really can’t do the action film." As a matter of fact, such a natural melancholy expression was due to the fact that "Poetry after Puberty" was in the final stage of full swing at that time. Monsters stayed in the studio almost every day and stayed up all night, and immediately went straight to the scene to shoot the MV the next day. Instead, it just presented the most natural and appropriate brand style of "Monsters with misty eyes".

　　　　You Are Not Really Happy, the title song described as "tears from the first note of the prelude string to the last note of the lead singer A Xin", was premiered on the radio a few days ago, and deeply moved fans enthusiastically discussed the meaning of words on the Internet. Many people even started to "listen to songs and make up stories" themselves. Some people were worried about A Xin and asked him not to think too much and be overly depressed. There are also fans who think that this song must be A Xin’s tailor-made song for the monster after learning that the monster is the leading actor in the MV, revealing the unknown secret of the monster. After the exposure of the MV premiere announcement in just 15 seconds, more fans and netizens expressed their eagerness to hear what jokes the monster said in everyone’s ear.

In terms of sectors, automobile disassembly concept, humanoid robot, metal copper and silicone were among the top gainers, while coal, Sora concept and CRO were among the top losers.

On the whole, stocks rose more and fell less, with more than 4,300 stocks in the whole market rising. The turnover of Shanghai and Shenzhen stock markets today was 944.5 billion, 62.7 billion less than that of the previous trading day, and the turnover fell below one trillion.

Northbound funds bought 10.326 billion yuan in the whole day, of which Shanghai Stock Connect bought 6.792 billion yuan and Shenzhen Stock Connect bought 3.534 billion yuan.

Today is the third Friday in March, which is the delivery date of monthly stock index futures.

MorningThe central bank issued a notice saying that the central bank carried out a 7-day reverse repurchase operation of 13 billion yuan, and the winning bid rate was 1.8%.At the same time, a one-year medium-term loan facility (MLF) operation of 387 billion yuan was launched, and the winning bid rate was 2.5%, which was the same as before.

Wind data shows that 10 billion yuan of reverse repurchase has expired today, and 481 billion yuan of MLF has expired.

existDelivery day effectoverlayThe funds are slightly tight.Under the influence of the Shanghai Stock Exchange 50, Shanghai and Shenzhen 300, CSI 500, CSI 1000 and other major indexes have been slightly adjusted in early trading; 40 minutes before the opening in the afternoon, the decline narrowed slightly, but it continued to fluctuate.

The change node appeared at 13:42, when a sudden wave of continuous buying pulled the index up significantly.

Since then, the market sentiment has gradually warmed up. Since this wave of rebound, the Shanghai Composite Index hasFriday’s Invincible Golden BodyIt’s also maintained,The Shanghai Composite Index has even been 5 consecutive days a week.Yes.

So who was at the bottom?

According to observation,First of all, there is a high probability that the "national team" will participate.Because SSE 50, CSI 300, CSI 500 and other broad-based ETFs have almost simultaneously increased their volume in the steepest pull-up section of the index.

Secondly, it is the accelerated bargain-hunting of northbound funds.

It is worth noting that in addition to the above-mentioned "national team", the funds involved in the explosion today alsoThere is a foreign giant.The figure, that is the world’s second largest index company.FTSE Russell（FTSE Russell）。

The company had previously announced that it would transfer 76 A shares to the index, the index.Changing positions happens to be today.(March 15th).

According to the market value at the end of February this year, after this round of adjustment, A shares will increase from about 5.71% to about 6.18% in the FTSE Russell Emerging Markets Index, and from about 0.55% to about 0.61% in the FTSE Global Index.

The author noticed that among these 76 newly transferred stocks, many stocks are available today.obviousTime-sharing transaction

for exampleCapital securities、Jianyuan trustIn a certain minute, a huge amount of buying suddenly appeared.

There are also imagesHigh-tech developmentsuchIn the minutes before the close, the stock price continued to increase in volume.

And,Late bidding stageThese stocks and even the whole market have seen huge purchases.

To be sure, this adjustment willBring incremental passive allocation of funds for A shares.It is a good thing.Some media reports pointed out that since the beginning of this year, foreign investment has continued to increase.Even in the crash in early February, foreign capital was not the main force to kill the crash.

In short, today’s market bottomed out and turned red, initially ending the continuous adjustment for many days this week, and planting optimistic expectations for next week’s market.

For the market outlook, some people pointed out that,The market has entered a critical stage..

First of all, the A-share market has rebounded a lot since 2635, and the yields of many institutions are also very impressive. In the future, there are only many variables in the whole environment, so at this stage, it is normal to have a cash mood. From the perspective of the overall market structure, artificial intelligence, new energy, consumption and nonferrous metals have also had a round of gains.This stage requires chip precipitation..

Secondly,A shares are entering a performance-intensive disclosure period.. On Wednesday, Industrial Fulian plunged in late trading because the expected performance on that day may not be as good as expected. However, the diving of the stock has greatly affected the market sentiment. Tonight, Contemporary Amperex Technology Co., Limited’s annual report will make a big debut. Although the performance forecast is good, the stock price is quite depressed this morning. In other words, if there is an expected rise, it will not move, and if it is less than expected, it will plummet. At such times, funds will be "awe-stricken".

Third,A number of policies are waiting to be introduced.. This morning, it suddenly came out that the policy details of the implementation methods and standards of the automobile trade-in action plan are being formulated. If it goes well, it is expected to be introduced in the second quarter. Subsequently, auto stocks changed. Beiqi Blue Valley approached the daily limit, and jiangling motors, Yaxing Bus, Jinlong Automobile, Jianghuai Automobile, Haima Automobile and China Heavy Duty Truck followed suit. There are many similar policies, such as the market value assessment plan of state-owned enterprises and central enterprises.

Fourth,Peripheral variables are increasing.. According to the Japanese news agency on March 14th, the Bank of Japan is expected to end the negative interest rate policy at its meeting in March, and make a final decision after the results of the spring wage negotiations are announced on Friday. The media reported that the Bank of Japan will end the negative interest rate policy at the interest rate meeting to be held next week, and pointed out that it will make a final decision after studying the preliminary findings of this year’s Spring Fight (spring salary negotiation between Japanese enterprises and trade unions, also known as "Spring Fight" by the market) on the 27th. At that time, it is not known how much impact it will bring to the global market.

Finally, let’s look at the plate.

Concept of automobile disassemblyIt rose more than 9%, ranking first in the A-share concept sector, setting off a wave of daily limit.

In the news, on March 13th, the State Council issued the Action Plan for Promoting Large-scale Equipment Renewal and Trade-in of Consumer Goods, which opened a new round of trade-in of consumer goods.The "Proposal" proposes that by 2027, the recycling volume of scrapped cars will be about doubled compared with 2023, the trading volume of used cars will increase by 45% compared with 2023, the recycling volume of used household appliances will increase by 30% compared with 2023, and the proportion of recycled materials in resource supply will be further improved.

The program also stimulatedEnvironmental protection plateToday is strong.

On the other hand,Cultivate diamondsPlate sumanthropomorphic robotThe plate is also more active when the market as a whole is weak, with the highest increase.

Regarding the former, since March, the market has been constantly spreading.Cultivate diamonds and raise pricesAccording to the news, some leading enterprises have reported that the current production and sales are full, and there is basically no inventory. The overseas demand continues to improve and the domestic recovery is also very good.

Wanlian Securities said that in the short term, the year-on-year growth rate of India’s cultivated diamond rough imports slowed down in January, and the export of cultivated diamond rough diamonds turned from negative to positive year-on-year, indicating that the demand for cultivated diamonds rebounded in January. In addition, the import of natural rough diamonds rose sharply year-on-year, and the decline of loose diamonds was narrowed year-on-year. However, the price of finished diamonds fell slightly, still fluctuating at a low level. In the medium and long term, with the gradual recovery of the macro-economy and the further popularization of the consumption concept of "please yourself", the downstream consumption demand of diamonds is expected to gradually recover. However, cultivated diamonds have the same composition and structure as natural diamonds, and have a greater advantage than natural diamonds in price. Combined with the education of downstream consumers by media and brands in recent years, the penetration rate of cultivated diamonds is expected to be further improved in the future.

As for humanoid robots,near futureThere are also new trends in the industry.

At the 2024 China Household Appliances and Consumer Electronics Expo, Haier Robot and Leju Robot jointly exhibited the first humanoid robot for family scenes in China — — Kuavo。 According to reports, Kuavo, as the first open source humanoid robot in HarmonyOS that can jump and adapt to multi-terrain walking in China, not only showed its control performance such as jumping and walking quickly, but also showed the hand operation results of washing, watering flowers, arranging flowers and drying clothes recently.

Open source securities said that there is no doubt about the prospect of humanoid robots in the case of giants entering the game. AI and software accelerate iteration, and hardware supply becomes the key to mass production of robots. Compared with the cognitive decision-making system whose performance has been greatly improved after AI empowerment, it is more difficult to acquire hardware with high reliability, high performance, light weight and low cost. No matter how the competition pattern of humanoid robot manufacturers is interpreted, mass production needs to be realized by reliable and low-cost hardware. The domestic supply chain with strong following, manufacturing and cost reduction capabilities is expected to usher in good results.
