How to balance the diet? Expert Interpretation of Reference Intake of Dietary Nutrients for China Residents (2023 Edition)

  On October 26th, an exclusive interview with DRIs was held in Beijing.

  Yang Yuexin, Chairman of China DRIs Revision Expert Committee and Chairman of China Nutrition Society, Ma Aiguo, Deputy Chairman of the Revision Committee and Executive Vice Chairman of China Nutrition Society, Ding Gangqiang, Deputy Chairman of the Revision Committee, Secretary of the Party Committee of China Nutrition Society and Director of the Institute of Nutrition and Health of China CDC, Yang Xiaoguang, Vice Chairman of China Nutrition Society and researcher of the Institute of Nutrition and Health of China Center for Disease Control and Prevention, Peng Xianwu, the supporting unit of DRIs revision and general manager of Amway (China) Science and Technology Innovation Center, attended the interview and interpreted the new revision.

Expert Interpretation of Reference Intake of Dietary Nutrients for China Residents (2023 Edition)

  Yang Yuexin introduced that the 2023 edition of China DRIs is the ninth edition. The revised expert committee and technical working group composed of nearly 100 nutrition experts lasted for three years. Based on the four basic principles of scientificity, advancement, integrity and continuity, the different reference intakes of 20 age groups including energy, nutrients and other dietary ingredients and pregnant women and lactating mothers totaled more than 70 nutrients and other dietary ingredients, which were revised and confirmed, and were held at the 14th Asian Nutrition Conference in September 2023.

  The revision of DRIs in 2023 mainly includes four aspects. First, the concepts and procedures have been improved and perfected. Different procedures for determining different reference values of nutrients have been newly formulated, and the technical points of each link of the formulation procedures have been uniformly determined. The concepts and connotations of recommended intake and specific recommended values for reducing the risk of diet-related non-communicable diseases have been further clarified and improved. Secondly, the basic reference values of China population were formulated and revised, including age grouping, representative weight, reference value of breast milk composition, recommended weight gain of pregnant women, PAL of physical activity level, etc. Thirdly, the new research results of nutrients and other dietary components in the past decade at home and abroad in the fields of function, evaluation, requirement, safety and prevention of chronic diseases have been included, and more research results targeting China residents have been included. Fourth, from the writing framework, format and other styles, it highlights the positioning of reference books centered on quantitative values.

Reference Intake of Dietary Nutrients for China Residents (2023 Edition) (DRIs)

  Peng Xianwu believes that this revision has far-reaching guiding significance for the big health industry, such as the data of newly added plant nutrients such as coenzyme Q10 and Lycium barbarum polysaccharide, and the quantification of nutrients such as proanthocyanidins, which will help Amway and industry to develop products and guide consumers to use them.

  Peng Xianwu introduced that in 2022, Amway and China Nutrition Society established Nutrilite Special Fund for Plant Functional Components and Health Research, aiming at attracting more research institutions and personnel to participate in the research direction of plant nutrients, opening up production, learning and research, transforming research results into products faster, and making more scientific research results benefit the public.

  This revision has greatly changed the protein intake of the elderly and the calcium supplement standard for adults. Yang Xiaoguang believes that China has entered an aging society, and the elderly and ordinary people can’t meet the demand for protein, which is easy to lead to sarcopenia. Therefore, it is necessary to improve the dietary structure of the elderly and increase the intake of protein. Yang Xiaoguang introduced: "The 2023 edition of DRIs revised the requirement of protein for the elderly aged 65 and above in China, and its recommended intake increased from 0.98 g/(kg day) to 1.17 g/(kg day), which is an important achievement".

  Ding Gangqiang said that in recent years, the health awareness of Chinese residents has been continuously strengthened, and dietary nutrition and healthy behaviors have been continuously formed, but chronic diseases related to nutrition are still increasing. It is hoped that the release of the 2023 edition of DRIs will further guide the needs of China residents in all aspects of dietary nutrition, especially how to achieve a reasonable and balanced diet, and complete the objectives of the second largest action of Healthy China Action-Reasonable Diet Action.

  The revision of DRIs has a wide range of significance and value. First, it has scientific value, which determines the types and quantities of nutrients that each person should consume every day qualitatively and quantitatively. Second, social value is an important basic data support for formulating relevant policies, regulations and standards; The third is the value of technical support, which plays an important guiding role in the dietary design and evaluation of collective feeding units such as schools and nursing homes, the nutrition labeling of prepackaged foods, and the product research and development of food enterprises.

Global news: US stocks fell across the board, gold continued to refresh, and Tesla’s share price fell by nearly 30% during the year.

  On Tuesday (April 2), Eastern Time, the second quarter of the US stock market seemed to have a bad start. The three major indexes of the US stock market fell across the board overnight. They all fell more than 1% in intraday trading, and the Dow fell nearly 400 points to a two-week low, the biggest daily decline in four weeks with S&P. The expectation of interest rate cuts in the first half of the year was frustrated, and the yield of US bonds rose again, which suppressed the market to some extent. However, the performance of gold is still strong and continues to refresh.

  At the close, the S&P 500 index fell 0.72% to 5205.81 points; The Dow Jones index fell 1.00% to 39,170.24 points; The Nasdaq index fell 0.95% to 16,240.45.

  In terms of US bond yield, the 10-year US bond yield once rushed above 4.4% to close at 4.36%, and the 2-year US bond yield, which is most sensitive to the Fed’s policy interest rate, closed at 4.70%.

  Since Powell reiterated last week that he was in no hurry to cut interest rates, the market sentiment has not been high. And overnight, internal officials of the Federal Reserve once again consolidated this statement, and market sentiment was once again hit.

  San Francisco Fed President Daley said that three interest rate cuts this year are a baseline forecast and can be increased or decreased if necessary. The former "big hawk" and Cleveland Fed President Meister also expect to cut interest rates three times this year, and it is not excluded to cut interest rates in June, and the reasons for cutting interest rates in May are insufficient; Both warned of the risk of cutting interest rates prematurely.

  It is worth noting that the economic data of the United States even triggered speculation about whether the Fed will cut interest rates three times this year. The data released on Tuesday showed that the number of job vacancies in the United States has not changed much compared with the previous value, or it indicates that the labor demand is still stable at a high level in the high interest rate environment.

  LPL Financial analysts pointed out that although the Fed does expect to cut interest rates sometime this year, the argument that interest rates will be higher for a longer period of time is playing a role again, so this worries the market. He also explained from another angle why the market will pull back. A healthy market really needs to pull back. The current trend is not necessarily a bad thing. The S&P 500 index has still risen by about 9% so far this year. Therefore, the market outlook still needs to keep a close eye on the US economic data.

  On the enterprise side, Tesla released the latest car delivery data, which was not as good as the market expectation. The share price fell by 4.9% overnight, and it has fallen by nearly one-third during the year, and its market value has been erased by 260 billion US dollars. The data shows that Tesla’s delivery volume in the first quarter decreased by 8.5% year-on-year to about 386,800 vehicles, which was far lower than the analyst’s previous average expectation of 449,080 vehicles, which was the biggest worse than expected in history. During the same period, about 433,400 vehicles were produced, which was also lower than expected.

  This is also the first time that Tesla has fallen below the 400,000-vehicle mark since the third quarter of 2022, a decrease of over 8.5% compared with the delivery of 422,875 vehicles in the first quarter of last year, recording the first year-on-year decline since the second quarter of 2020.

  In the first quarter, Tesla faced a double blow of reduced demand for electric vehicles and high interest rates. Analysts had previously lowered their expectations for Tesla’s delivery. Some analysts pointed out that Tesla would experience the first year-on-year sales decline since the early days of the epidemic.

  In addition, Tesla also faced many obstacles in the first quarter, such as the interruption of the supply of spare parts in the Red Sea caused by the attack of Houthi militia and the temporary suspension of production in the German factory. Although the next generation model is the key to growth, the production of this model is not expected to start until late next year, which means that the company may face the risk of slowing down growth before this.

  [Hot stocks]

  Among the popular US stocks, Microsoft fell by 0.74%, Google A by 0.60%, NVIDIA by 1.01%, Amazon by 0.16%, Apple by 0.70%, Meta by 1.23%, AMD by 2.53%, Arm Holdings by 2.07% and Netflix by 0.02%.

  Due to the delivery of Q1 far less than expected, Tesla fell by 4.9%, and has fallen by nearly one-third during the year.

  Global stock index

  In the European stock market, the FTSE 100 index in Britain fell slightly by 0.22% to 7935 points. The French CAC40 index fell slightly by 0.92% to 8130 points. Germany’s DAX index fell 1.13% to 18,283 points.

  In Asian stock markets, the Hang Seng Index rose 2.36% to 16,932 points. The index of state-owned enterprises rose 2.58% to 5961 points. The Nikkei 225 index fell 0.73% to 39,625 points.

  [China Stock Market]

  Nasdaq China Jinlong Index closed up 0.32%. In terms of popular Chinese stocks, Pinduoduo fell by 0.77%, TSMC by 0.88%, Weilai by 2.16%, Xpeng Motors by 2.26%, Alibaba by 0.61%, Baidu by 0.08% and Netease by 1.88%.

  [foreign exchange commodities]

  The US dollar index rose first and then fell, once standing above the 105 mark in intraday trading, and once fell to an intraday low of 104.67 during the US session, then rebounded and finally closed down by 0.19% to 104.81.

  Gold futures for June delivery in the New York Mercantile Exchange closed up 1.09% at $2,281.80 an ounce, a record closing high, having risen to $2,297.70 an ounce in intraday trading. May silver futures closed up 3.39% at $25.923 an ounce.

  Geopolitical risks have enhanced the attractiveness of gold, while traders have avoided the shadow cast by the strong economic data of the United States on the prospect of the Fed raising interest rates.

  Oil prices continue to rise due to supply concerns. WTI crude oil rushed above $85 in intraday trading, rising more than 2% in the day, and continued to hit a new high since October last year, finally closing up 1.76% to $85.47/barrel; Brent crude oil also hit a new high since October last year, and finally closed up 2.12% to $89.27/barrel.

  [Highlights]

  The Fed reiterated that it is not in a hurry to cut interest rates, but it is still possible to start in June?

  San Francisco Fed President Daley said that three interest rate cuts this year are a baseline forecast and can be increased or decreased if necessary. Regardless of changing the inflation target, the continuous rise in oil prices will become a problem; The former "Great Hawk" and Cleveland Fed President Meister also expect to cut interest rates three times this year, and it is not excluded to cut interest rates in June, and the reasons for cutting interest rates in May are insufficient; Both warned of the risk of cutting interest rates prematurely.

  Job vacancies in the United States in February were slightly higher than expected

  The voluntary turnover rate is the lowest since 2020, and the number of layoffs is the highest in nearly a year. The number of JOLTS vacancies in the United States in February was 8.756 million, slightly better than expected, and the value was revised down to 8.748 million before January. The voluntary turnover rate in February was 2.2%, the lowest level since 2020. Due to the increase in layoffs in the leisure and hotel industries, the number of layoffs has risen to the highest level in the past year.

  Tesla’s quarterly delivery dropped for the first time in nearly four years, and its market value has evaporated by $260 billion in the year.

  On Tuesday, Tesla Corporation, an American electric vehicle manufacturer, released a report on automobile production and delivery in the first quarter of 2024. According to the specific data, Tesla delivered a total of 386,810 vehicles in the first three months of this year, far below the analyst’s previous average expectation of 449,080 vehicles, which was the biggest worse than expected. This is also the first time that the company has fallen below the 400,000-vehicle mark since the third quarter of 2022, which is over 8.5% lower than the delivery of 422,875 vehicles in the first quarter of last year, recording the first year-on-year decline since the second quarter of 2020.

  Intel’s report shows that the loss of its foundry business expanded in 2023.

  In a document submitted by Intel on Tuesday, Intel said that the sales of its new manufacturing division, Intel Foundry, in 2023 were $18.9 billion, down from $27.5 billion in the previous year, and the operating loss increased from $5.2 billion in 2022 to $7 billion. It is estimated that the loss will reach its peak in 2024 and will be realized at the operational level "in the middle of now to the end of 2030". Intel shares fell more than 2% after the report was released. Intel’s entry into outsourcing chip production is one of the biggest transformations in the company’s history. CEO Pat Gelsinge’s recovery plan also includes restoring the company’s once impeccable technological advantage, which the chip giant lost in the years before he took office in 2021.

  A major breakthrough in AI pharmaceutical! Stanford SyntheMol model develops new antibiotics

  According to a report by Stanford Medical College on March 28th, researchers from Stanford Medical College and McMaster University have made important progress in this field. They have developed an AI model called SyntheMol, which can synthesize drugs and create formulas for chemists in the laboratory.

  The model creatively designed six new drugs for drug-resistant bacterial strain Acinetobacter baumannii, which is one of the main pathogens causing antibiotic resistance-related deaths. The model not only created a new drug structure, but also provided a detailed formula for chemical synthesis, enabling chemists to synthesize these drugs in the laboratory.

  Abbott’s heart valve repair system has been approved by FDA to provide patients with new treatment options.

  On Tuesday, US medical and health company Abbott announced that its heart valve repair system has been approved by the US Food and Drug Administration (FDA), which is suitable for patients with potentially fatal heart disease. Abbott’s minimally invasive transcatheter TriClip repair system aims to treat tricuspid regurgitation (TR), which is a disease in which the valve between the right ventricle and the right atrium of the heart cannot be closed normally, resulting in blood reflux. Abbott has incorporated TriClip into its so-called "Fab 5" () equipment portfolio, which is expected to promote the company’s sales growth in the next few years, representing Abbott’s technological innovation and market leadership in their respective fields.

Seven membership systems in the era of e-commerce

In the retail circle, the membership system has been iterative, so we might as well look at the membership logic from Amazon, Nike, Sephora, Starbucks and Xiaomi.

This article comes from WeChat WeChat official account:Retail Watch (ID: On Retail), author: Wang Ziwei

For retailers, the membership system is basically unavoidable. Let’s take a look at what the most mainstream membership system in the e-commerce era is like.

From a global perspective, there are seven most common forms:

1. Integral-hierarchy system

2. Service subscription system

3. Entity subscription system

4. Charity system

5. Sharing cooperation system

6. Community system

7. TOKEN system

I. Integral-Hierarchy System

This is almost the simplest one. In short, every time you spend X yuan, you get Y points. The more you spend, the higher the score.The only variable seems to be that there may be reward points at different times and through different channels, such as 5 times points for in-store consumption during the celebration period and 10 times points for e-commerce consumption during the Black Five/double 11 period.

Let’s take a foreign example, that is, the clothing brand "North"(North Face)",its integral system is called" VIPeak ".

For consumers, understanding this system is also very simple, that is, for every dollar spent, they get 10 points-whether online or offline, if they spend at outlets, they get 5 points for every dollar.

These points can be used in future consumption. To this end, North Face allows users to manage their accounts, buy goods, see points and redeem rewards through the App.

This is the simplest point system, through which consumers are willing to continue to shop. North Face is a typical single-level membership system.

Based on this logic, there will be a multi-level membership system, generally and periodically.(e.g. 1 year)The consumption amount or points are positively related.The characteristic of hierarchical system is that the higher consumers spend, the more rewards they get.

This level itself is also a gamification system, which links consumption with "playing". In the United States, a classic case is the beauty brand e.l.f

Consumers with 0-100 points are at the first level, consumers with 101-400 points are at the second level, and those with 401 points or above are at the highest level-the more membership points, the more unique the rewards.The uniqueness of the highest level is an important factor that urges consumers to buy more goods.

From the point of view of points, the first-level consumers get 2 points for spending 1 dollar, the second-level consumers get 4 points for spending 1 dollar, and the third-level consumers get 6 points for spending 1 dollar, and consumers can get corresponding services by using points.

Similarly, Starbucks in the United States also has this hierarchical system, which is divided into green card levels.(Green Level)And gold card level(Gold Level).

When the user has less than 299 stars, it is a green card level, and will enjoy the privileges of getting 2 stars for every $1 spent, birthday gifts, mobile payment, placing orders in advance, and free refills in the store; When the number of stars reaches 300 or above, the user will be upgraded to the gold card level. At this time, he will not only enjoy all the green card level permissions, but also double the star accumulation day every month, get a gold card membership card with his name printed on it, and exchange free food or coffee every 125 stars.

In addition to getting stars through consumption, there are also some activities in Starbucks APP, such as going to the store for consumption at a specific time, getting extra stars, and buying specific goods to get extra star rewards.

Second, the paid subscription system-service category

In the payment system, consumers need to pay a monthly fee or an annual fee to become a VIP. Generally speaking, there must be a solid consumer base.After all, it is difficult for you to make a new user become a paying member with little contact with you, so this payment system is basically used to maintain experienced users.

In addition, this payment system must have membership benefits, otherwise users don’t have to pay you in vain.

The most classic case is Amazon. Now Prime with an annual fee of $119 only needs $79 at the earliest, but only one problem was solved in that year, that is, it was guaranteed to be delivered free of charge within 2 days. This was the biggest problem of e-commerce in that year, otherwise a product would only be available in 2-3 weeks, and even if the price was superior, it could not wait.

Later, many functions were added to Prime for free, such as Amazon music, Amazon photos (unlimited storage of photos) and Amazon videos.(Watch all kinds of movies, dramas and original dramas at will)Wait a minute. In 2018, according to data from investment bank JP Morgan, the annual membership fee of $119 is worth about $784, which can be said to be over-valued.

The extreme, even extreme, is Costco.After covering the cost of goods, personnel and management expenses, the income generated by its goods is almost used up, so that its final profit returned to shareholders and membership fees are almost equal.

Third, the paid subscription system-commodity category

Another logic of the payment system is, "subscription box.(Subscription Box)Type ",that is, the subscription of physical items such as products/commodities.

The goods in the "subscription box" generally need to be purchased repeatedly. Take Bean Box as an example, it is the subscription of coffee-normal purchase is the normal price, but if you subscribe, you can always receive coffee on schedule within a cycle, and you can enjoy a discount.The essence is a behavior of directly locking consumers and locking demand, and then it may be the reverse supply chain.

Another advantage of this subscription is that it can increase the lifetime value of customers-from the case of Bean Box, can it be the same if you let consumers buy once and realize repeated service for six months, and let consumers buy for one month and one month?

Amazon has a similar service, and some products can be "subscribed" directly on the purchase page-usually with a discount of about 5%.

Fourth, the charity system

Discount can be a component of the membership system, but it is not necessary.

Therefore,The logic of the charity system is that you are attracting consumers with your own values, thus establishing a stronger relationship.The more common way is that enterprises donate a percentage of their income to charity, such as donating the money to charities, disease research institutions, animal protection organizations and so on.

A small evolutionary version here is that the enterprise will give you several optional donor institutions, and you can choose the one you are willing to donate. This is the case with The Body Shop in America, which introduced animal welfare into its membership system.

In addition to receiving rewards and VIP treatment, consumers can also choose to donate a percentage of their spending to Born Free USA, an animal welfare institution. This is also because The Body Shop has always emphasized environmental responsibility.

This logic lies in that the communication with consumers is not only the exchange of goods and services, but also the integration of values, which in turn makes the loyalty of consumers come to a different and uncontested field.It can be said to be a "blue ocean strategy of values".

V. Sharing cooperation system

A consumer will not only have a membership card, so the demand is also diverse. It can be said that consumers’ spending time is very idle, and the core is whether businesses from different formats can "cut leeks" together-buy electronic products from you, shoes from me and snacks from him.

Therefore, consumers will also want more flexibility in rewards. At this time, what is needed is cross-industry cooperation, which is equivalent to consumer sharing. After all, every enterprise has private domain traffic and data is single-segmented. If(Where permitted by law)Realize the docking of data, then almost draw the whole life of consumers.

In the United States, Nike’s membership system is like this. It has cooperated with Apple, Classpass and Headspace. These companies are not randomly selected, but can be linked to sports. They belong to the cooperation of several enterprises with sports as their core values.

At the same time, Nike also has a variety of apps for different sports to help members achieve their exercise goals. Then as long as the consumer’s behavior can be recorded by the App, then you can get a reward.

Japan’s Sakya Bookstore is also this logic, which focuses on life: through the T-card system, the parent company of Sakya Bookstore has opened 887,000 stores in 179 Japanese companies in May 2018, realizing the universality of points, and the profit does not come from the points themselves, but from the big data insight of consumers. Because consumer data is no longer just a single book purchase, eating, shopping, but all the synthesis.

In China, this kind of cross-industry cooperation is also gradually emerging. For example, JD.COM Plus can give you an iQiyi member.It is also the opening of data and traffic sharing between the two parties, which in turn turns traffic into "reservation".

VI. Community system

Beauty cosmetics brand Sephora(Sephora)Beauty Insider, a membership system, must be said. On the one hand, this system can be upgraded to three grades based on consumption, and every dollar spent in each grade can get different grades of points feedback.(1 dollar for 1 point, 1.25 points, 1.5 points respectively)At the same time, there are opportunities to get more exclusive services with the improvement of grades in the traditional "hierarchical system".

Besides,The biggest feature of Sephora’s membership system is the establishment of a community-to communicate with various members, find inspiration, participate in exclusive activities and so on.At this time, members of Sephora come to the brand community, and Sephora can understand the needs of consumers and then optimize its product design.

This logic also exists in China, that is, in Xiaomi’s community, a group of fans gather in the community to communicate with each other and put forward their own needs, and Xiaomi’s product manager can collect relevant information and update the corresponding system: users feel that they are valued, and Xiaomi has obtained consumer demand and met consumer demand, and both sides are happy.

Seven, TOKEN type

The last one is the TOKEN logic in the blockchain, or,Is similar to "asset securitization"(ABS)The idea of "assets token" should be called as a kind of "assets token"(ABT)”。

This kind of logic can be seen in China. At present, it can be simply divided into two types. The first type is "commodity tokenization", which is represented by the second-hand e-commerce enjoyment theory, and the second type is "behavior tokenization". I think the representatives are interesting headlines and today’s headlines. Let’s look at it together:

"Commodity Tokenization"

The problem with second-hand e-commerce is that the seller wants to sell an item that is "emotionally connected with himself", and based on game theory, the buyer will directly regard all second-hand goods as having a problem, forming a "lemon market effect" and paying a very low price, or, no matter how wonderful your price is and how perfect the goods are, I will ask for a 20% discount first and then post it-as long as I have sold something on idle fish once.

This will greatly reduce the efficiency of the transaction, and the seller will usually feel very uncomfortable, and finally there may be problems on the "supply side", which will have a negative effect on the market.

The logic of enjoying things is very interesting, that is, instead of introducing money, users use small red flowers. Users earn small red flowers through various behaviors, such as signing in and sharing, and then "exchange" other people’s goods with their own small red flowers. Because the little red flower is not anchored with the RMB, so,Users will participate in the purchase according to their real needs, rather than the "chopping behavior" caused by "consumerism".As a result, the pressure on both buyers and sellers is reduced, which greatly promotes the circulation efficiency of goods.

This logic actually exists in offline channels, that is, "moon cake tickets", that is, the moon cakes are placed there, and the person who finally gets the tickets goes to a specific place to pick up the goods. As for the intermediate process-the goods are not moving, and the tickets are flying around, which greatly reduces the cost. The logic of this set of freight tickets is "online" and combined with the mode of second-hand e-commerce, which forms the theory of enjoying things.

"Behavior Tokenization"

The second logic is "behavior token", which is the case with interesting headlines.

To put it simply, users can be rewarded for all their behaviors on the APP, including reading gold coins, watching videos, sharing gold coins, and rewarding users with "tokens" in a different way, and then this "token" is every cycle.(The period of interesting headlines is "1 day")Will be cleared, converted into RMB, accumulated to a certain amount, you can withdraw cash-or buy other goods directly in the APP.

The logic is simple,Retaining customers requires costs, so why not give these costs directly to customers as much as possible?And these sources of RMB are also simple, just divide the gross profit of each cycle directly. So now, we will find that many apps have this logic, such as the extreme version of today’s headlines, various headline apps, and various information apps.

Rhododendron in Liangshan Scenic Area of Sichuan was killed by tourists: the whole branch was broken and the barbecue was lit.

  In May, the alpine rhododendrons in Liangshan Prefecture, Sichuan Province bloomed one after another, and the rhododendron sea all over the mountains attracted many tourists. This weekend, the Rhododendron Sea in Haikou Ranch, Puge County, Liangshan Prefecture became popular on the Internet, and was known as "the most beautiful Rhododendron Sea in Liangshan". However, in these two days, this flower sea was "poisoned" by tourists.

  On May 6th, Haikou Ranch was crowded with tourists who heard the news. According to incomplete statistics, more than 800 self-driving cars and more than 2,000 tourists entered that day. According to the local traffic police, the roads entering the pasture were lined up for several kilometers, and the traffic was once paralyzed. Before this weekend, the azaleas in Haikou Ranch were just a "secret place" known to a few people, not known to the outside world.

  On the morning of May 7, many Liangshan netizens forwarded another scene of Haikou Ranch in the circle of friends: after the tourists dispersed, a large amount of garbage was left on the ground, and the beer bottles they drank staggered. Sadly, some tourists break the branches at will and take photos in their hands.

  According to the photos provided by netizens, in a rhododendron viewing place, some people even dug up rhododendrons by roots and put them on pickup trucks to transport them away. Some netizens posted a photo taken in the Rhododendron Sea in Longjiaoshan, Huili County. After the whole flower was broken, it was ignited and burned to make barbecue wood.

  In Liangshan, azalea is called soma flower in Yi language, which is the welcome flower of Liangshan. "Soma is crying." Seeing these acts of destroying azaleas, many Liangshan netizens and tourists are very sad and have forwarded and condemned them in the circle of friends.

  The tourism department reminded that it is hoped that tourists can take care of the environment, take away garbage, don’t start with rhododendron, and protect the pure land of Haikou Ranch. At the same time, Rhododendron in Liangshan Mountain generally grows above 2800 meters above sea level. Below this altitude or the temperature is too high, it is difficult to survive, and it is useless to dig down the mountain.

  On May 7th, Puge County convened an emergency meeting of tourism, public security, forestry, environmental protection and other departments to deal with a series of problems caused by the recent sharp increase of tourists in Haikou Ranch. At present, Puge County Forest Public Security Bureau is also involved in the investigation.

Regarding the prevention of influenza, WHO’s latest recommendation of influenza vaccine strains in 2024-2025.

Foreword

Influenza virus can cause seasonal influenza, and may even cause a pandemic outbreak. Influenza virus is a negative-strand RNA virus with complex classification, numerous subtypes and easy mutation. At present, it is recognized that the best way to prevent influenza is vaccination. In order to ensure the effectiveness of the vaccine, the World Health Organization (WHO) updates the composition of the vaccine strain every year.

Changes of influenza vaccine strains in the northern hemisphere in 2024-2025

In order to keep the vaccine effective, it is necessary to update the components of influenza virus vaccine regularly. After analyzing the global influenza virus epidemiology, etiology and vaccine serology, WHO announced the recommendation of influenza vaccine components in the northern hemisphere from 2024 to 2025 on February 23, 2024.

?

Trivalent chicken embryo culture vaccine

an A/Victoria/4897/2022 (H1N1)pdm09-like virus

an A/Thailand/8/2022 (H3N2) -like virus

a B/Austria/1359417/2021 (B/Victoria lineage)-like virus

?

Trivalent cell culture or recombinant protein vaccine

an A/Wisconsin/67/2022 (H1N1)pdm09-like virus

an A/Massachusetts/18/2022 (H3N2)-like virus

a B/Austria/1359417/2021 (B/Victoria lineage)-like virus

?

Tetravalent chicken embryo and cell culture or recombinant protein vaccine

The following components are added on the basis of trivalent vaccine

a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus

Since March 2020, the naturally occurring B/Yamagata virus has not been confirmed. WHO thinks that it is not necessary to use B/Yamagata virus as a component of influenza vaccine, and it should be removed from the component of influenza vaccine. Where tetravalent vaccine is still used, the composition of B/Yamagata line is consistent with the previous recommendation.

Comparing the composition of influenza vaccine in the northern hemisphere from 2023 to 2024, it was found that the change of composition was mainly due to the difference of H3N2 virus strains:

Vaccine types

2023-2024

2024-2025

Trivalent chicken embryo culture vaccine

A/Darwin/9/2021 (H3N2)-like virus

A/Thailand/8/2022 (H3N2) -like virus

Trivalent cell culture or recombinant protein vaccine

A/Darwin/9/2021 (H3N2)-like virus

A/Massachusetts/18/2022 (H3N2)-like virus

Painting Jianghu’s "Wind Spell" issued a rising version of the forecast 7.13 to lift the country again.

1905 movie network news From, to, almost every summer, there will be a national ramble out of the tight encirclement. This year, the first film in the series of painting rivers and lakes — — The curse of the wind. After the trailer was released at Cannes Film Festival in 2014, five years later, The Wind Spell was finally produced and will be shown to the audience on July 13th. Let many fans sigh, and finally wait for you.

In the preview released this time, Xia Lan used the five elements of gold, wood, water, fire and earth to fight fiercely with fierce beasts. According to legend, only the power of wind can compete with it, revealing the meaning of the title "Wind Spell" and setting up a world view full of Chinese style. In the poster released together, the young volley confronted the huge gluttony, revealing a stirring story of the rise of a young hero.

 

The most valuable guoman IP The Wind Spell permeates the national wind into every detail.

From its first broadcast in 2012 to the present, the painting rivers and lakes have created many high-quality comic dramas, such as Xia Lan, Bad Man, Soul Master, Cup Don’t Stop, and Changed Students, which can be said to be the most cosmopolitan and vital national comic, and also regarded as the most valuable national comic IP in the industry. Therefore, the first movie of painting rivers and lakes was placed high hopes by anime fans to help the rise of the country.

In the preview, the mythical gluttony in this world, Xia Lan uses the power of five elements to compete, and the teenager wants to be a hero when he enters the rivers and lakes … … The setting of the whole world outlook in the Wind Mantra is full of Chinese style. The same is true of the details. Fierce beasts, which are mostly composed of curved designs, and rivers and lakes in noisy streets are trying their best to convey an oriental aesthetics, which conforms to the audience’s imagination of "national ramble". Director Liu Kuo almost "digs" these details to the extreme. "Let the China audience like it first and see it comfortably."

 

Hold back the movie dream for six years and develop the only domestic animation engine. "grab back" some audiences for Guoman

The completion of the Wind Spell took five years of preparation and three years of production. But the time behind it is far more than that. In the mind of director Liu Kuo, this movie dream has been held back for too long. "Although I had a dream of making movies long ago, I still held back. I want to make myself strong first. Because the country in my heart is made by ourselves. "

With this in mind, director Liu Kuo and the team started to develop a "Datura Engine" for animation. After six years of "darkness before dawn", China’s 3D animation finally has the original ability of the whole process. After tens of thousands of minutes of animation polishing, "Wind Spell" was finally launched. The film is about to be released, and Liu Kuo revealed his hope that "in the case that the China market has been occupied by Hollywood and Japanese animation for a long time, we can win back some audiences for domestic animated films in China"!

Low-carbon, Agriculture and Rural Areas Make Great Achievements —— On behalf of the Commissioners, talk about the low-carbon development mode of agriculture and rural areas

  "Low carbon" is one of the hottest words at the two sessions this year. CPPCC members’ proposals are piled up with "low carbon", and NPC deputies discuss "low carbon" hotly, and group discussions are also inseparable from the topic of "low carbon". "Low carbon" has become the "new favorite" that people pay attention to for a time. So, what is "low carbon" and what does agriculture and rural areas do in developing low carbon? The insights of the deputies explain the "low carbon" of agricultural and rural development from different angles.

  The meaning of the transformation of agricultural development mode

  "Low-carbon agriculture is first of all an idea and a development direction of agricultural transformation development mode. The essence of the low-carbon concept is to save energy. " Shang Xunwu, member of Chinese People’s Political Consultative Conference and deputy director of Gansu Agriculture and Animal Husbandry Department, said.

  Zhang Quanguo, member of Chinese People’s Political Consultative Conference and dean of the School of Mechanical and Electrical Engineering of Henan Agricultural University, further explained low-carbon agriculture. He said: "Agriculture, as the basic industry of the national economy, is one of the main sources of greenhouse gases, and it is also increasingly affected by the greenhouse effect. How to formulate low-carbon agricultural development policies and reduce carbon emissions in agricultural production has increasingly become the focus of attention from all walks of life and one of the key areas to be considered in regional economic development. It is imperative to change the agricultural production mode as soon as possible and develop low-carbon and high-efficiency agriculture. "

  At present, in China’s agricultural production mode, some production habits do not meet the requirements of low carbon, which is neither economical nor polluting the environment. Taking fertilization as an example, Meng Tieying, deputy stationmaster of soil and fertilizer station in Xincheng County, Guangxi Province, said that because there is a lot of local rain, heavy rain usually causes farmland to be flooded. Traditional fertilization methods make the loss of fertilizer very serious, which not only increases the cost, but also pollutes the environment. Farmers urgently need a fertilizer that can control the release rate. Data show that the low utilization rate of chemical fertilizers in China is the main reason for environmental pollution caused by chemical fertilizers. In addition to crop absorption and utilization and soil residue, more than 50% of nitrogen is not absorbed by crops and lost to farmland, which has caused a series of environmental and food safety problems, such as eutrophication of water, soil hardening, greenhouse effect and degradation of agricultural products quality.

  Zhang put forward a proposal to develop low-carbon agriculture. He believed that it is necessary to cultivate the management concept of low-carbon agriculture, vigorously promote the innovation of agricultural production system, implement the management assessment responsibility system for energy saving and emission reduction in agriculture-related production, and gradually develop and improve agricultural energy efficiency standards from the height of national laws and regulations. He also proposed that we should pay attention to the research on low-carbon agriculture, including the integrated application research of carbon emission reduction and carbon sink expansion technologies such as energy, environment, building structure, water supply and drainage, and green space.

  Science and technology support low carbonization of agricultural production

  Shang Xunwu said that there are many articles that can be done to develop modern agriculture and realize the development of agriculture from extensive to refined. It can be said that in the agricultural field, it is very feasible to achieve low carbon.

  He said that many aspects of agriculture can consider how to achieve low carbon. For example, he said that from the perspective of agricultural inputs, such as water resources, agriculture consumes a lot of water, but now the way of using water is unreasonable, causing great waste. Water is used for irrigation, but also consumes electricity. If water is saved, irrigation energy is saved, and it is low-carbon.

  Zhang Quanguo gave a concept of low-carbon agriculture. "Low-carbon agriculture is a modern agricultural development model. Through various means such as technological innovation, institutional innovation, industrial transformation, and new energy development and utilization, energy consumption and carbon emissions are reduced as much as possible to achieve a win-win situation for agricultural production development and ecological environment protection." He further explained that low-carbon agriculture is the further development of eco-agriculture and green agriculture, which not only advocates less use of chemical fertilizers and pesticides and efficient agricultural production like eco-agriculture, but also pays more attention to the reduction of overall agricultural energy consumption and carbon emissions in the process of planting, transportation and processing, when the use of energy such as electricity, oil and gas is increasing.

  Shang Xunwu gave his own suggestions on how to promote low-carbon agriculture. First, strengthen the role of technology and promote low-carbon technology in agriculture. The second is the innovation of production mode. For example, intensive production, through cooperatives and professional associations to promote centralized production and management, improve efficiency.

  Zhang Quanguo also holds the same view: supporting the sustainable development of agriculture by improving the technical content of low-carbon agriculture.

  Taking the scientific and technological development of fertilizer research and development as an example, China has supported the low-carbon fertilization in fertilizer technology research and development. Liu Jianwen, a representative from Agricultural Economics Center of Agriculture Bureau of Linshu County, Shandong Province, said that in recent years, fertilizer enterprises in Linshu have achieved remarkable results in research and development, production and popularization of slow-release fertilizers in low carbon. For example, he said that hundreds of slow-release fertilizer products developed and promoted by Jin Zhengda Group, the largest production base of slow-release fertilizers in Asia, are suitable for field crops in China. Xu Weigang, deputy director of Wheat Research Center of Henan Academy of Agricultural Sciences, summed up the advantages of slow-release fertilizers in low carbon: slow-release fertilizers can control nutrient release according to crop nutrient demand, which changes the shortcomings that fertilizers can not meet the different demands of crops at different growth stages because of rapid dissolution and nutrient loss, and can greatly improve the utilization rate of fertilizers, protect the environment, save energy, simplify crop production technology and help farmers reduce costs and increase income.

  For supporting the development of low-carbon agriculture with science and technology, Zhang put forward more specific suggestions. He suggested: First, improve the low-carbon agricultural infrastructure in the core grain producing areas. Intensify integration, focusing on the construction of modern facility agriculture demonstration parks, ecological animal husbandry, grain (leafy vegetables) functional areas and other projects to lay a good foundation for accelerating the development of modern agriculture. Second, strengthen the cultivation of excellent varieties adapted to low-carbon environment. At the same time, we should vigorously promote the innovation of farming system and promote a number of development models such as stable grain and high efficiency, farming-pastoral cycle, and paddy-upland rotation. Third, greatly reduce the use of chemical fertilizers and pesticides, and reduce the carbon content in agricultural development. Such as using manure, compost or organic fertilizer instead of chemical fertilizer, and increasing soil nutrients through returning straw to the field.

  The era of low-carbon rural life is coming.

  Low-carbon mode not only has great achievements in agricultural production, but also the conditions for developing low-carbon in rural areas are ripe. Zhang Quanguo said that to develop low-carbon agriculture, it is necessary to develop new energy sources in rural areas and realize the diversification of rural energy consumption structure. Such as comprehensive utilization of straw, livestock manure, solar energy and other renewable energy resources to meet the needs of rural domestic cooking energy, rural domestic electricity and domestic hot water.

  Twenty years ago, Tengtou Village, Ningbo City, Zhejiang Province, which wrote environmental protection into the villagers’ convention and established the only village-level environmental resources protection committee at that time, was the forerunner of rural low-carbon. Fu Qiping, the general secretary of the village party branch, said that building a "low-carbon" ecological village was the golden key to rural development. "To develop a’ low-carbon’ economy and achieve harmony between man and the natural environment, rural areas should also shoulder the burden." Fu Qiping believes that the future "low-carbon" life is a high-quality, healthy and civilized lifestyle.

  "A large number of solar cookers in the western rural areas will greatly reduce greenhouse gases such as carbon dioxide produced by burning firewood (grass, wood), gas and coal." Ren Qixing, member of Chinese People’s Political Consultative Conference and deputy director of the Population, Resources and Environment Committee, said. He said that the western region of China has a long sunshine time and relatively rich solar energy resources, which is most suitable for popularizing solar cookers in large quantities. Ren Qixing suggested establishing financial support policies and giving appropriate financial subsidies to the purchase of solar cookers in rural areas. At the same time, vigorously support solar cooker manufacturers, give tax incentives, and help enterprises improve output, quality and scientific and technological content to meet the needs of promoting the use of solar cookers in rural areas.

  Coincidently with Ren Qixing, Hao Yuan, member of Chinese People’s Political Consultative Conference, vice governor of Gansu Province and chairman of the Provincial Federation of Industry and Commerce, is also very concerned about the utilization of solar energy. He put forward the Proposal of Implementing the Solar Energy "South Wall Plan" at the two sessions. Its core idea is to use the south facade of the building facing the sun, including the heat collection wall, air collector and additional sunshine room on the south facade, to convert the collected solar radiation energy into heat energy as much as possible, and then transfer it to the room to achieve the purpose of heating and warming.

  In order to promote a lower-carbon lifestyle in rural areas, Zhang also suggested that the development and application of biogas technology should be widely promoted, and at the same time, the agricultural and sideline residues should be fully utilized to improve the low-carbon utilization of straw. He said that China’s annual crop straw output is about 700 million tons, half of which can be used as energy, equivalent to 150 million tons of standard coal. He suggested focusing on the research and development of "trinity" complete technology and equipment for low-carbon utilization of straw. The core grain producing areas such as Henan Province are selected to carry out innovative research and demonstration application of low-carbon agricultural renewable energy and energy-saving engineering technology integration.

  It is understood that the purpose of the "Shui Mu Hsinchu Yingchun Cup" National Youth Mathematical Comprehensive Ability Exhibition is to promote mathematical culture, stimulate the interest of primary and secondary school students in learning mathematics, explore more outstanding mathematics talents, develop their intelligence, popularize mathematical science, help the majority of young people discover their own mathematical talents, and enable students to fully understand, like and enjoy mathematics, and constantly improve their mathematical literacy. The proposition of this activity is universal and interesting, and all the topics seem simple, but students need to think hard in the process of solving them, and there are many solutions, which are helpful for students to open up their minds and stimulate the potential of mathematical comprehensive ability. Some topics combined with real-time hot spots make mathematics, an abstruse subject, return to life, and encourage students to apply what they have learned to solve practical problems in life with mathematical thinking.

  From now on, the "Shui Mu Hsinchu Yingchun Cup" national youth mathematics comprehensive ability demonstration activity will be carried out one after another throughout the country, and the majority of young people who love mathematics can sign up for the activity.

In 2019, the Nobel Prize in Chemistry was announced, and three scientists, including the "father of lithium batteries", won the prize.

  CCTV News:On the morning of October 9, local time in Sweden, the Royal Swedish Academy of Sciences announced in Stockholm that it would award the 2019 Nobel Prize in Chemistry to John B. Goodenough, M. Stanley Wittingham and Yoshino Akira in recognition of them."developing lithium-ion batteries"The contribution of. They will share the prize of 9 million Swedish kronor (about 6.5 million yuan).

  Lithium-ion batteries have completely changed our lives and are used in all applications, from mobile phones to laptops and electric cars. Through the work of the winners, this year’s Nobel Prize winner in chemistryIt laid the foundation for a wireless and fossil fuel-free society..

  In the early 1970s, M. Stanley Wittingham, who won this year’s Nobel Prize in Chemistry, was developing.The first functional lithium batteryAt that time, the great power of lithium was used to release its external electrons.

  John B. Goodenough, winner of the 2019 chemistry prize.The potential of the lithium battery is doubled.It creates suitable conditions for more powerful and useful batteries.

  This year’s Nobel Prize winner in chemistry, Akira Yoshino, succeeded inPure lithium was removed from the battery.Instead, it is based on lithium ions that are safer than pure lithium. This makes the battery feasible in practice.

  John B. Goodenough isFather of lithium batteryHe made the lithium battery smaller, larger and more stable in use, thus realizing commercialization and at the same time starting the process of portable electronic equipment. At present, he is Professor department of mechanical engineering of the University of Texas at Austin, USA. At the age of 97, he is a famous solid physicist, the inventor of cathode materials of lithium cobaltate, lithium manganate and Ferrous lithium phosphate, and one of the founders of lithium-ion batteries. He designs new materials by studying the relationship between chemistry, structure and solid electron/ion properties, and solves material science problems. Sony produced the world’s first commercial lithium battery after adopting Goodenough theory in 1991. Since then, mobile phones, cameras, hand-held cameras and even electric vehicles have entered the era of portable new energy.

  M Stanley Whitingham is currently a professor of chemistry and director of the Institute of Materials and the Department of Materials Science and Engineering at Binghamton University, State University of New York.

  Akira Yoshino, a Japanese chemist, is currently a researcher at Asahi Kasei and a professor at meijo university. He was commended by Zi Zi. Yoshino is the inventor of modern lithium-ion batteries, and has won the highest honor in engineering, the Global Energy Award and the Charles Stark Draper Award. (CCTV reporter Hao Xiaoli)
