Why did the explosion of Crimea Bridge become a ＂landmark event＂ in the conflict between Russia and Ukraine？

[Global Times-Global Network Reporter Bai Yiyi Chen Qingqing] According to Russian news agencies and other Russian media reports on the 8th, a tanker fire accident occurred on the Crimean Bridge across the Kerch Strait in the early hours of local time, and some sections of the bridge were destroyed. According to the Russian Counter-Terrorism Committee, the accident was caused by the explosion of a truck, which caused the tanker to catch fire. The investigation commission of the Russian Federation said that it had filed a case for the explosion accident.

Analysts told the Global Times reporter on the 8th that the destruction of the Crimea Bridge will become a landmark event in the Russian-Ukrainian war, which may cause Russia to launch high-intensity retaliation against Ukraine. The incident means the spiral escalation of the conflict, and both sides of the war have been hostile to each other. It is worth mentioning that the Crimean Bridge incident is another destruction of key infrastructure after the leakage of the "Beixi" pipeline. Once this means becomes the norm, it will mean the security risks and global tensions faced by all countries will rise linearly.
According to the video image released by RIA Novosti on the 8th, after the incident, the fire over the Crimea Bridge rose several meters high, many cars were filled with smoke, and the bridge deck collapsed and fell into the sea. According to the assessment of the All-Russian Insurance Union, the loss caused by the Crimean Bridge incident is 200 million to 500 million rubles. Peskov, press secretary of the Russian President, said that it is impossible to predict the time for repairing the Crimean Bridge.
According to officials of the Crimean authorities, the Ukrainian side should be responsible for this. Up to now, Ukrainian officials have not publicly admitted that the Ukrainian army launched the attack. However, the Ukrainian Air Force posted on social media that "in the morning on the Crimean Bridge, the fuel tank caught fire. Part of the road was destroyed! Everything will belong to Ukraine! " The director of the Ukrainian President’s Office also issued a tweet saying, "The Crimean Bridge incident is only the beginning, all illegal things will be destroyed, all stolen things will be returned to Ukraine, and the Russian occupation will be completely expelled."
Cui Heng, an assistant researcher at the Russian Research Center of East China Normal University, told the Global Times reporter that the destruction of the Crimea Bridge may lead to "high-intensity retaliation" by Russia. He explained that because of the importance of the Crimea Bridge, Russia had issued warnings and delineated a "red line" many times before. If the Crimean Bridge explosion is finally proved to be a deliberate attack, it will be a test of whether Russia can keep the "red line". "In some people’s view, Russia has no choice but to use high-intensity retaliation to convince the outside world of Russia’s determination to draw the" red line "and stick to it."
Wang Xiaoquan, a researcher at the Russian Institute of Eastern Europe and Central Asia of the China Academy of Social Sciences, also believes that Russia may take strong retaliatory measures. He analyzed the Global Times reporter and thought that this means that the risk of attack on the civilian infrastructure in the rear of Russia and Ukraine will greatly increase in the future, and the war wounds of both sides will be more difficult to heal. In contrast, Ukraine’s ability to protect and repair civil infrastructure is weak, and people’s lives will be even more difficult in the event of an attack.
According to public information, the Crimea Bridge is a railway and highway bridge, which is the traffic lifeline connecting Russia and Crimea. It is 19 kilometers long and 7.5 kilometers across the sea. It was opened in May 2018, and Russian President Vladimir Putin attended the opening ceremony of the bridge. In Russia’s special military operations, the Crimean Bridge has been playing a key role in logistics support and troop transport. The bridge is also considered as a symbol of Russia’s control of Crimea.
Recently, with the intensification of the conflict between Russia and Ukraine, the Crimean Bridge has become one of the focuses of confrontation between the two sides. In August this year, there was an explosion near the Crimea Bridge, and Kerch started the air defense system. In August this year, Podolyak, chief adviser to the Office of the President of Ukraine, said in an interview that the Crimean Bridge was a "legitimate target" for the Ukrainian armed forces. Earlier, danilov, secretary of Ukraine’s National Security and Defense Committee, also said that if Russian supplies and equipment are reinforced through the route of the Crimea Bridge, Ukraine will definitely attack the Crimea Bridge once the opportunity arises. In response, peskov, the press secretary of the Russian President, said at that time that the Ukrainian side’s relevant remarks were unacceptable.
How will the destruction of the Crimean Bridge affect the trend and strength comparison of the Russian-Ukrainian battlefield? Cui Heng told the Global Times reporter that the Crimea Bridge provided supplies and troops for Russian troops in the direction of Hellson and Nikolayevsk, and the destruction of the bridge directly affected Russia’s current defense in Hellson and its attack in Nikolayevsk, which was the main purpose of attacking the Crimea Bridge. "More importantly, in Russia’s view, the Crimean Bridge is symbolic, representing Putin’s prestige, the centripetal force of the Crimean people towards Russia and the pride of Russians. The attack on the bridge is intended to hit the morale of the Russian people. "
However, Wang Xiaoquan believes that the headquarters of the Russian Black Sea Fleet is located in Sevastopol on the Crimean Peninsula, but the main logistics support and force transportation of the Russian Army on the battlefield in eastern Ukraine are not from the Crimean Peninsula, and the Crimean Bridge is only one of the transportation channels connecting the Crimean Peninsula with the mainland, and it can also be transported by ferry. The damage to the Crimean Bridge has a very limited impact on the battlefield situation and power contrast.
According to media reports from Tass and RIA Novosti, the traffic on the Crimea Bridge will be blocked until October 31st. After the bridge fire accident, the Crimean authorities released a message on the 8 th local time that the local basic necessities inventory can meet the consumption for two months, but in order to avoid snapping up, the sales of food groceries will be restricted. According to the Russian Ministry of Energy on the 8 th, the supply of automobile fuel in Crimea is sufficient, and the supply is enough to last for 15 days. At present, relevant departments are working to ensure the continuous supply of local fuel.
It is worth noting that the explosion of the Crimea Bridge is another destruction of key infrastructure after the recent "Beixi" pipeline leak. Analysts pointed out to the Global Times reporter that the above two incidents were "off-the-counter moves" outside the conventional military operations. "These" off-the-counter moves "were used, which is a very bad signal that the parties involved in the conflict broke the rules."
"In the short term, this means a spiral escalation of the conflict, and both Russia and Ukraine have already waged endless hostility. From a broader perspective, once the destruction of key infrastructure becomes the norm in the future, the national security risks faced by all countries will rise, and the tension of the global situation will rise linearly. " Cui Wei analyzed this way.

JD.COM consumption observation： advanced beauty and skin care consumption from immediate effect to long-term pursuit, from external modification to natural health, from follow-up consumption to demand

From immediate effect to long-term, from external modification to internal health, from following the trend to rational decision-making, after experiencing the development stage of rapid growth and concept flooding, the beauty and skin care market in China is entering a more mature and calm new cycle. Today’s consumers in China no longer blindly follow the trend and are not easily moved by marketing words, but slow down, examine the real needs and return to the essence of products.

Recently, JD.COM Consumer and Industry Development Research Institute and JD.COM Beauty launched a topic research, and through the dialogue with 1,000 consumers, we learned about the current pursuit and use concept of beauty and skin care products. The Research Report on Beauty Consumption Trends shows that consumers’ understanding of beauty is being reconstructed, and their pursuit of beauty and skin care products points to three core keywords: long-term, natural and streamlined. Behind the change is not only the diversification of aesthetic concepts, but also the overall awakening of health awareness. Everyone’s pursuit of "from the inside out" health status has extended to the field of beauty and skin care.

Specifically, in terms of consumer demands for beauty and skin care products, consumers’ core demands for beauty and skin care focus on health, nature and anti-aging, while paying attention to the emotional value and social attributes of products. The survey shows that 44.4% of the respondents choose "long-term skin care" and 39.0% choose "healthy beauty from the inside out", both of which emphasize the long-term management of skin health, which shows that long-term healthy skin care has become the mainstream demand. In terms of beauty cosmetics, more consumers prefer natural makeup effect, with 33.0% of the respondents choosing "no makeup is better than makeup" and 24.9% choosing "mother gives birth to good skin". They refuse the over-decorated "false face" and pursue "natural good state". On the whole, the demand for anti-aging also shows an obvious trend of "pre-positioning", and 34.8% of the respondents pursue "anti-aging before showing old age". 22.7% of the respondents pursue "self-pleasure" and 21.9% pay attention to "social soft power", which reflects the psychological and social attributes of beauty and skin care consumption.

In terms of consumption concept, the overall consumption of skin care and beauty cosmetics presents three characteristics: "long-term, naturalism and minimalism". The survey shows that 43.3% of the respondents pursue "the effect of daily maintenance is greater than beauty", and 39.2% choose "long-term". Consumers are more willing to pursue simple ingredients and long-term effects, and pay attention to the matching of products with their own needs. They are not obsessed with improving the "immediate state" but pursuing the promotion of "long-term state". At the same time, 30.1% of the respondents are more willing to present "natural makeup", 27.0% of the respondents recognize "precision and simplicity", and generally prefer to pay less attention to makeup effect and skin care methods and pursue "simple beauty".

Is beauty more important or skin care more important? What do they mean to consumers? For the vast majority of consumers, both of them are "indispensable", but they also have their own emphasis. However, whether it is beauty or skin care, consumers want to improve their own state. Beauty and skin care is no longer just a step for "remediation", but a set of long-term systematic projects of "prevention+repair+maintenance".

In addition, the survey results have more findings about the consumption trend of beauty and skin care:

· Basic nursing is the mainstream, and the demand for advanced efficacy is rising. Research shows that facial cleansing, lotion/cream and sunscreen products are the "golden triangle" of basic skin care. The increase in the frequency of use of facial essence and lotion indicates that consumption is advanced to functional products. In the pursuit of efficacy, moisturizing and hydrating are still the core, and advanced needs such as anti-aging/anti-wrinkle, whitening and oil control are obvious. In addition to basic care, consumers’ product selection and skin care concepts have become more focused, focusing on long-term use effects.

· Consumers will pay attention to the matching degree between different product ingredients and their actual needs, and pursue the long-term health of the skin. According to the survey, only 4% of the respondents never pay attention to ingredients. At the same time, consumers pay attention to multi-angle segmentation of their own needs and "matching on demand" has become an important trend. The survey shows that 54.9% of the respondents will subdivide "efficacy (such as moisturizing, whitening, anti-aging and barrier repair)", nearly half of the respondents will subdivide "skin type (such as oily skin, dry skin, sensitive muscles and acne muscles)" and 44.6% of the respondents will subdivide "skin feeling (such as moisturizing and refreshing)".

· "Medical beauty" and "cinema-level" skin care products gradually gained a certain market recognition. In the choice of functional products consumption, 74.4% of the respondents used functional products such as acids and alcohol. At the same time, consumers pay great attention to "safety and reliability", "use effect" and "cost performance" when choosing "medical beauty" products. From the perspective of "long-term doctrine", consumers pay more attention to whether "medical beauty" skin care products can help them get long-term quality experience rather than immediate obvious effect, and safety surpasses others and becomes the most important decision-making factor.

· The pursuit of makeup has become the core demand of this consumer’s beauty products consumption, and daily and efficient products have become the core category of beauty products consumption. The survey shows that commuter makeup and pseudo-plain makeup are the most frequently pursued makeup styles, and they prefer clear and natural makeup and even skin color. In the process of purchasing, 47.6% of the respondents emphasized the "skin feeling" experience, preferred low-cost beauty products and looked forward to a more natural feeling.

· In addition to pursuing the efficacy of products, consumers are also very concerned about the purchase channels when purchasing, and choose a more trusted platform to ensure the product’s "integrity and fidelity". The survey shows that "authentic" is one of the important factors that affect the decision-making of most consumers. 92.4% of the respondents attach importance to authentic products, and 60.6% of them regard it as a "decisive factor". The emphasis on "genuine products" is also reflected in the choice of consumption channels. 81.0% of users buy beauty and skin care products through JD.COM, and 67.6% of the respondents choose this channel because of "genuine protection".

· Domestic beauty and skin care brands have risen. According to the survey, among the skin care brands, the domestic head brand has the highest vote rate, accounting for 42.5%; In the choice of make-up, domestic head brands and imported high-end brands have the same votes, accounting for 33.2% and 35.2% respectively. In the survey, consumers believe that the advantages of domestic beauty and skin care products are "more suitable for Chinese skin" (56.8% of the votes) and "high cost performance" (52.8% of the votes).

· Consumer behavior is becoming highly scene-oriented. Gifts, as an important consumption scene, drive the consumption growth of beauty and skin care product gift boxes. In addition, early adopters and travel drive the consumption growth of sample beauty products. According to the survey, 72.1% of the respondents have bought beauty and skin care gift boxes, the main purpose of which is to give gifts; At the same time, many consumers will choose to buy small packaging products, and 82.2% of the respondents have bought samples/trial packages. In the usage scenario, 45.6% of the respondents travel and 42.3% of the respondents use them for tasting new products.

Long-term pursuit, advanced skin care and on-demand segmentation

Skin care needs from basic care to anti-aging needs.

Cinema-level skin care products are gradually moving from "niche" to "mass"

The development of the times drives the change of ideas. When skin care becomes an important part of life, consumers trust data, respect science, and pursue a scientific skin care system with traceable ingredients, visible efficacy and sensible experience. At the same time, skin care has also been given more emotional value-from "daily task" to "self-ritual".

Generally speaking, basic care is still the ballast stone in the skin care market, but consumers are no longer satisfied with single moisturizing and hydrating, and advanced needs such as anti-aging, whitening, anti-aging and repair are rising, which also promotes the development of skin care products in the direction of refined functions to better meet the diversified needs of consumers. According to the survey, among the skin care products most commonly used by consumers, "facial cleansing", "lotion/cream" and "sunscreen" rank in the top three, which constitute the "golden triangle" of basic skin care, accounting for 54.2%, 50.8% and 48.1% respectively. 43.6% of "facial essence" and 41.2% of "make-up water" followed closely, showing that they gradually advanced to functional products on the basis of basic nursing.

The same advancement is also reflected in the use target of skin care products, which is above the mainstream demand of "moisturizing" (51.1%) and "hydrating" (50.0%). 36.8% of the respondents chose "anti-aging/anti-wrinkle", 35.0% chose "whitening", 32.4% chose "oil control" and 31. This is also in line with the skin care feeling that consumers expect. According to the survey, 36.6% of the respondents expect the feeling of "youthful skin" in addition to the basic "refreshing and non-greasy", "water-oil balance" and "safety without burden".

In addition to the functional needs of skin care, consumers also pay attention to the sensory experience and emotional resonance brought by skin care, and the skin care experience of "healing system" is very important for this session of consumers. According to the survey, 65.8% of the respondents expect skin care products to bring "comfortable texture and touch", while 49.9% choose "pleasant smell", which is much higher than the "packaging design" chosen by 23.8% and the "sense of using ceremony" chosen by 33.2%. Most consumers expect the emotional value provided by skin care products from "self-feeling".

At the same time, 47.6% of the respondents regard skin care products as "necessities to maintain skin health", and 41.0% of the respondents expect skin care products to be "functional solutions for specific skin problems"; 41.1% of the respondents believe that skin care products can help them "improve their external image and internal self-confidence", and 35.5% of the respondents believe that they can "relax and heal themselves through skin care". It is not difficult to find that the "practicality" and "feeling" of skin care products are equally important to consumers.

Facing all kinds of skin care products, consumers’ attitude is becoming more and more professional, and "transparent ingredients" and "scientific proportion" have become the cornerstones of trust, and they think that clinical data or expert endorsement is more reliable. It has become a normal state for consumers to rationally choose skin care products by paying attention to ingredients and understanding the ratio. According to the survey, 62.1% of the respondents always pay attention to ingredients, and only 4% of the respondents never pay attention to ingredients. Among the users who pay attention to ingredients, 46.5% of the respondents want to "avoid harmful ingredients", 40.3% want to "avoid allergens" and 33.6% want to "confirm effective ingredients".

Consumers are more clear about their actual needs through multi-angle segmentation, so as to make rational decisions and choose skin care products that better match their actual needs, and the choice is more clear and systematic. The survey shows that 54.9% of the respondents will subdivide "efficacy (such as moisturizing, whitening, anti-aging and barrier repair)", nearly half of the respondents will subdivide "skin type (such as oily skin, dry skin, sensitive muscles and acne muscles)" and 44.6% of the respondents will subdivide "skin feeling (such as moisturizing and refreshing)".

Focusing on functional products, 74.4% of the respondents used functional products such as acids and alcohol A, which had a wide audience. "Medical beauty" skin care is in the stage of market education. Consumers are willing to pay a premium to get "real and effective" and "safe and reliable" in the consumption decision of "medical beauty" and "cinema level" skin care products. The data shows that when choosing medical beauty products, 49.2% of the respondents are most concerned about whether they are safe and reliable, 34.7% are concerned about the effect and speed of use, and 30.8% are concerned about the price and cost performance, which is the most important decision-making factor for consumers to choose medical beauty products and cinema-level skin care products.

Simplification of ingredients, light burden on skin, and high adaptation have become the new criteria.

Make-up demand returns to "true beauty"

Make-up consumption pays attention to natural makeup effect, pragmatism and self-satisfaction.

Reject the "mask feeling" and embrace the "original feeling". The makeup effect should be natural, the function should be practical, and the experience should be pleasant-for this consumer, the natural makeup effect is really popular. The consumption of beauty products is shifting from "concealer" to the carrier of "self-confidence expression" and "self-pleasure", showing a trend of coexistence of complexity, practicality and emotional value.

From the perspective of makeup style, 55.8% of the respondents prefer "commuting daily makeup" and 38.2% prefer "pseudo-plain makeup". From the two dominant makeup styles, consumers prefer natural and efficient makeup. In daily commuting scenes, makeup and lipstick are most frequently used. Specifically, lipstick accounts for 40.3%, liquid foundation/cream accounts for 36.7%, makeup remover accounts for 36.4%, followed by air cushion for 31.0% and concealer for 29.1%.

In terms of specific makeup effect, most consumers are more pursuing "clear and natural" makeup effect. The survey shows that 39.3% of the respondents prefer "clearness and naturalness" and 32.5% attach importance to "even skin color". Consumers hope that make-up "looks like no make-up" and highlights the true beauty, rather than just covering up the true state of skin through make-up products, which also drives consumers to choose more light and natural beauty products.

In the process of use, consumers value the actual value of make-up products and expect a pleasant experience in the process of use. According to the survey, 42.4% of the respondents expect to bring "pleasant experience (such as no powder, easy to use)" through make-up products, and 47.6% of the respondents pay attention to "skin feeling (such as lightness, durability and no dryness)" when buying make-up products, which shows that "practicality" has become an important decision-making factor for consumers when facing make-up products.

Make-up products are not "face-changing tools", but "self-confidence blessing devices", which are an important carrier of consumers’ self-expression and emotional management, and an important tool to highlight self-confidence and increase "social capital". According to the survey, consumers are more looking forward to "pleasing themselves" by using make-up products, more than half of the respondents are looking forward to "improving their color and looking more energetic", 42.3% of the respondents are looking forward to "enhancing their self-confidence and making themselves more comfortable in social interaction" and 38.8% of the respondents are looking forward to "self-pleasure and the ceremony of making up to please themselves". 23.5% of the respondents often adjust their makeup, and 45.7% of the respondents occasionally adjust their makeup. This year’s consumers are willing to adjust according to the actual needs, and makeup has become an important part of improving their own state and gaining a sense of healing.

"practicality" and "sensibility" in the consumption of beauty cosmetics and skin care products

Imported high-end brands firmly occupy the technical highland, and domestic brands break through with "high cost performance"

Scenario demand-driven gift box and sample consumption growth

In the process of consumption of beauty and skin care products, consumers not only pay attention to the practical and tangible parts such as ingredients, efficacy, price, channels and packaging, but also care about the high-dimensional feelings of brand stories, use experience and emotional identity. Consumers are becoming more rational, professional, emotional and scene-sensitive. They not only pursue the balance between efficacy and experience, but also pay attention to the safety of ingredients and the guarantee of authenticity, and are also willing to pay for emotional value and self-expression. Driven by the change of consumer demand, domestic brands have risen rapidly with the advantages of cost performance and localization, but in high-end markets and international brands, they still have advantages in ingredient technology and brand accumulation, and consumer behavior is also highly scene-oriented.

In the purchase decision, consumers become more rational, thinking that "efficacy is the starting point of purchase, and genuine products are the bottom line of transaction", and consumers are still "pragmatists". The survey shows that "efficacy", "skin feeling" and "authentic" are the three core factors, and the proportion of respondents is 52.4%, 47.5% and 43.1% respectively. "Authentic" is extremely important to consumers’ decision-making. Over 90% of consumers will pay attention to whether beauty and skin care products are genuine or not. Among them, 60.6% of the respondents think that "authentic" is a "decisive factor" in the decision-making of beauty and skin care products, and 31.8% of the respondents think that this is an "important factor". In order to meet the demand of "buying genuine products", 81.0% of the respondents are used to buying beauty and skin care products through the platform of JD.COM, and 67.6% of the respondents believe that the main purpose is to choose platforms such as JD.COM to run their own "genuine products protection". It can be seen that for the vast majority of consumers, channel trust and genuine guarantee are unshakable bottom lines.

Values are also an important factor affecting consumption decision-making. Social responsibility, environmental protection concept and cultural self-confidence have all become components of a brand and a product, and brand values will gradually affect consumption choices. According to the survey, 24.5% of the respondents will "give priority to brands with values", and 16.7% of the respondents refuse to buy products that do not meet their own values. It can be seen that values are becoming a filter for consumption decisions of beauty and skin care products.

In the process of using beauty and skin care products, consumers want not only the results, but also the process. Experience upgrading and emotional resonance have become an important concern of consumers. In terms of product meaning, 51.5% of the respondents regard beauty and skin care products as "daily necessities to care for the skin and enhance the image", 41.2% of the respondents think that it is a source of happiness that can "please oneself and bring happiness and satisfaction", and 34.8% of the respondents think that it can "help improve self-confidence". In terms of use value, in addition to the actual efficacy, 51.4% of the respondents expect a "more comfortable experience" and 45.1% of the respondents hope that the product can "relieve stress and bring pleasure".

This has also affected consumers’ consumption expectation of beauty and skin care products. According to the survey, 30.7% of the respondents expect that "the product effect will reach or even exceed expectations" and 24.7% of the respondents expect that "the purchase and use process will make them feel happy and satisfied". It is not difficult to find that the product strength is always the absolute core, and the consumption always revolves around whether the product is really effective and whether it brings a pleasant experience.

When consumers buy beauty and skin care products, they will not only pay attention to the efficacy and price of the products themselves, but also pay attention to the brands. In terms of skin care products, 42.5% people tend to choose domestic head brands. Respondents believe that the products of these brands can achieve the effect of "more suitable for Chinese’s skin", and the products mainly focus on basic cleaning, face cream and other daily high-frequency use categories. In the choice of domestic brand products, there are still some people who tend to choose cutting-edge domestic brands, and are willing to try brand products that are newly listed or have never experienced themselves. The reasons for choosing products are "cost performance" and "new ingredients". The proportion of people who tend to choose imported high-end brands such as SK-II and Hailan Mystery is 36.7%, and more than half of the respondents think that high-end imported brands have "guaranteed product quality" and "guaranteed technology accumulation and word-of-mouth in efficacy". These consumers are highly sensitive to the actual effect and safety of products, and will pay more attention to imported high-end brands in products such as facial essence and eye cream/eye essence. Different from skin care products, the votes of imported high-end brands in cosmetics are slightly higher than those of domestic brands, among which the proportion of imported high-end brands in perfume/fragrance and base makeup products is higher, and lipstick/lipstick products made in China are more concerned.

Consumer behavior is becoming highly scene-oriented. Gift scenes drive the consumption growth of beauty and skin care products gift boxes, while early adopters and travel drive the consumption growth of sample beauty products. According to the survey, 72.1% of the respondents have bought gift boxes. For the purpose of purchase, 50.8% of the respondents are for their own use and 35.7% are gifts, which are two important consumption scenarios of beauty and skin care product gift boxes. "High cost performance" and "efficient decision-making" are two important reasons for consumers to buy beauty and skin care product gift boxes, accounting for 46.7% and 39.6% of the respondents respectively. The sample/trial outfit is widely accepted. Over 80% of the respondents have bought the sample/trial outfit, and their main motives are "traveling" and "trying something new", accounting for 45.6% and 42.3% respectively. The consumption of beauty and skin care products is changing with the scene and the demand. And more than 90% of users think that if the sample/trial experience is good, they will buy formal clothes. "Try before you buy" has become a popular choice, and "experience" has been placed as one of the core links of consumption decision-making. In essence, consumers vote of confidence for products through personal trial.

The beauty and skin care market in China is undergoing a profound change from external modification to internal health, from passionate pursuit to rational choice, from functional satisfaction to emotional resonance. Consumers are willing to actively study ingredients, rationally compare efficacy, attach importance to genuine products, and are also eager for products to bring emotional value and realize self-expression.

When consumers talk about beauty and skin care products, they expect the actual efficacy and experience brought by beauty and skin care products, and refuse the extra burden and pressure. Beauty and skin care is a life behavior, but also an independent and sober attitude-not perfect, but healthy and natural; Not an instant change, but a long-term companionship; Instead of following the trend with passion, it is concise and effective, which essentially stems from consumers’ respect and recognition of self-demand, and others’ recognition and second, self-acceptance is the way home.

China’s beauty and skin care market is entering a new stage of paying equal attention to rationality and emotion, which is a more rational, delicate and confident consumption era. It belongs to consumers who clearly know what they want and are willing to pay for truth, health and self-pleasure. Let’s participate together and be better ourselves in the new era of beauty and skin care consumption.

　　On the morning of November 18th, the second group interview of the third world internet conference entrepreneurs was held in Wuzhen Internet International Convention and Exhibition Center Network Theater. Wang Xing, CEO of Meituan Review, Yao Jinbo, CEO of 58 Group, Li Ya, CEO of Little Information, Kelly Y Zhou, founder and CEO of Zhihu, Wang Xiaofeng, co-founder and CEO of mobike Science and Technology, Liu Chengcheng, founder and CEO of 36Kr, and other representatives of Internet companies answered reporters’ questions on the theme of "innovation drives the benefit of mankind". The group interview was presided over by Jiang Jun, director of the Network News and Information Dissemination Bureau of the National Internet Information Office.

　　Wang Xing said that the value of life service in internet plus lies in the combination of network technology and traditional business, making everyone’s life more comfortable and convenient. He believes that for the O2O industry, after the breadth of users reaches a certain level, it is more important to tap the depth of users. He suggested that there are three ways to deepen internet plus at this stage: the first is to launch a search method with updated interface and more efficient algorithm based on artificial intelligence and big data; The second is deep integration with traditional industries; The third is to seek international development.

　　Yao Jinbo believes that the mission of "58 City" is to make people’s lives more convenient through the Internet. For users, the quality of service they get is the most important. Only when the enterprise service is well done can the growth rate of the number of users be guaranteed. In the process of seeking development, enterprises continue to give back to society and benefit mankind, which is the value and due responsibility of Internet enterprises.

　　Kelly Y Zhou believes that it is becoming a trend for users to pay for knowledge. Practice has proved that knowledge sharing has high market value, and useful information can become customized and personalized knowledge goods, so that knowledge providers and sharers can obtain direct benefits. This is an innovation based on the change of information consumption demand. Information providers and demanders have their own needs, which is beneficial to everyone.

　　In response to a reporter’s question, Li Ya said that personalized reading has become a standard in the era of mobile Internet. He believes that although the information pushed based on simple intelligent recommendation algorithm can cater to users’ interests, it lacks value. The combination of "personal tailor" and "value reading" is the future direction of reading evolution and network culture development. While encouraging users to actively express their interests through search, subscription, etc., it can help users better obtain truly valuable content for their work and life.

　　Wang Xiaofeng believes that when many people encounter problems like traffic congestion and air pollution, they mostly consider seeking solutions from the government or other angles. However, as entrepreneurs, we should improve people’s living environment, make our life simple and healthy, and make the relationship between people more harmonious through the application of innovative technology.

    In response to a reporter’s question, Liu Chengcheng said, the data show that as of the third quarter of this year, the Internet entrepreneurial innovation situation in various places has maintained a high level of activity, but entrepreneurs must better combine the Internet with the real economy and truly create value before they can get investors’ attention.

Decheng District： 35 high-frequency government affairs services can be ＂done nearby＂ in Wanda Business Circle.

Qilu Evening News Qilu Yidian reporter Zhang Lei correspondent Ai Min Zhang Lixin
"Going to the mall is not only for shopping, but also for the convenience of the people. I really didn’t expect it!" On September 27th, Ms. Xie, a citizen who was shopping in wanda plaza, Texas, found that she wanted to run the business license registration in the government service hall before she happened to see the guidance catalogue of "political-business cooperation" set up by the service desk of Dezhou wanda plaza Commercial Management Co., Ltd., and she came to consult the relevant materials with an attitude of asking by the way. When she was told that she could be assisted by the agent of Wanda Service Desk all the time, and the materials were fully prepared and submitted to the examination and approval bureau, the postal staff could directly submit the license after the examination and approval. The convenience of all this benefits from the strategic cooperation agreement of "political and business cooperation" signed by Decheng District Administrative Examination and Approval Service Bureau and Dezhou wanda plaza Commercial Management Co., Ltd.
In order to further deepen the "one-time success", around the structural reform of the supply side in the field of government services, we will further expand the cooperation field according to the principles of "mass point, commercial super-connection, postal operation and government operation", and integrate the service modes of "running nearby" and "running from home" to "running at most once". On September 27th, Decheng District Administrative Examination and Approval Service Bureau held a signing ceremony for the strategic cooperation agreement of "political and business cooperation" with Dezhou wanda plaza Commercial Management Co., Ltd., which unveiled the "Government Convenience Service Point" in wanda plaza. Since then, the District Administrative Examination and Approval Service Bureau has delegated the first batch of 35 high-frequency items (see the guidance catalogue for details) including business licenses, food business licenses and public places hygiene licenses to the "Government Convenience Service Point" in Wanda Shopping Mall, realizing that government services can be handled nearby and more.
The people who handle affairs can take the way of doing things nearby, bring materials to the staff of the "Government Convenience Service Point" at the wanda plaza General Service Desk for consulting services, and at the same time call the postal telephone Commissioner’s hotlines 0534-12345, 0534-228675 and 15954777187, and the postal staff will respond within 5 minutes, and arrive in wanda plaza within 30 minutes after the response to handle the uploading of materials for the people, and accept the materials for administrative examination and approval.
At the same time, the people who handle affairs can also adopt the "530 door-to-door service" home-based mode, and the people who handle affairs in wanda plaza business district can also call the above-mentioned hotline of postal telephone Commissioner immediately to make an appointment for door-to-door service by telephone. The telephone attendant will inform the application materials at one time and immediately distribute the order to the political and postal service Commissioner after confirming that the materials are complete. The postal service Commissioner will respond within 5 minutes and confirm the time and address with the people who handle affairs, and make a door-to-door preliminary examination and receipt of materials within 30 minutes, and the accepted materials will be delivered to the administrative examination and approval department. By taking advantage of the advantages of supermarkets and postal terminal outlets, we adopt the mode of "530 door-to-door service" and implement a new model of government service of "mass point, supermarket access, postal service and government office", so that the masses can run from "at most once" to "don’t run at all" and realize that government services can be done nearby and at multiple points.
Setting up a "government convenience service point" in Shangchao to create a "political and business cooperation" service system for the coordinated development of the government and enterprises is an innovative convenience move in Decheng. "The implementation of the’ political and business cooperation’ service has achieved a win-win situation for many parties. Citizens can do things conveniently nearby, which also increases the potential customers of shopping malls, and at the same time diverts people who go to government service centers and other related units to do things, thus reducing their pressure. This service model has lasting vitality. " Guan Jinghua, general manager of Dezhou wanda plaza Commercial Management Co., Ltd. told reporters.
The relevant person in charge of the Decheng District Administrative Examination and Approval Service Bureau also said that relying on Wanda Shopping Mall’s "government convenience service point" can not only bring tangible convenience to the masses and enterprises, but also bring more customer flow and business volume to the shopping mall through expanding services, which can attract the masses to take the initiative to go to the shopping mall to handle government service business and promote the growth of shopping mall business circle. It is a beneficial practice for the government and shopping mall institutions to complement each other and integrate development. In the next step, the district examination and approval bureau will take this cooperation as an opportunity to actively promote the refined, integrated and personalized development of the "political-business cooperation" model, actively explore new measures, new ways and new mechanisms to optimize services, further tap the potential of political-business cooperation, enhance the level of cooperation, deepen the level of cooperation, adjust and increase service items in a timely manner according to the needs of the masses and the maturity of matters, continue to introduce more convenience service measures, and achieve win-win cooperation among the people serving Decheng. Make every effort to create a first-class ecological environment for government affairs and consumption, and make new and greater contributions to promoting high-quality economic and social development and building a new era modern new Dezhou demonstration zone that is "rich, beautiful and strong"!

[Li Xiang China] Deeply understand and grasp the mission and task of comprehensively promoting the great rejuvenation of the Chinese nation with Chinese modernization.

　　General Secretary of the Supreme Leader pointed out in the Party’s Report to the 20th CPC National Congress that on the basis of long-term exploration and practice since the founding of New China, especially since the reform and opening-up, our Party has successfully promoted and expanded Chinese modernization through theoretical and practical breakthroughs since the 18th National Congress. Based on the mission of the new era and new journey, our party solemnly declares that from now on, the central task of the Communist Party of China (CPC) is to unite and lead the people of all ethnic groups in building a socialist modernization power in an all-round way, realize the goal of the second century, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization.

　　The Communist Party of China (CPC)’s exploration and practice of leading and promoting Chinese modernization.

　　The development model of any country and society will not come into being out of thin air, but is the product of its own social and historical movement. Since modern times, China’s struggle to save the nation from extinction has been faced with the choice of modernization road from the very beginning. The Westernization Movement, the Reform Movement of 1898 and the Revolution of 1911 all attempted to promote modernization in China, but these explorations and attempts failed.

　　The failure of China’s modernization movement in modern times profoundly illustrates a truth: it is not feasible to take the capitalist road in semi-colonial and semi-feudal China, and it is also not feasible to take the westernized modernization road. The birth of the Communist Party of China (CPC) is a major historical turning point in the development of China’s modernization. Since then, China’s modernization has a strong leadership and a correct direction, and the people of China have a bright development prospect for their hard work for modernization and the great rejuvenation of the Chinese nation.

　　The Communist Party of China (CPC) united and led the people of all ethnic groups in China to win the great victory of the new-democratic revolution, broke the old system that hindered the development of modernization, realized the national independence needed by modernization, fundamentally changed the development direction of China society, cleared the obstacles and created the necessary premise for promoting the development of China’s modernization.

　　After the founding of New China, marked by the establishment of the basic socialist system, China entered a new stage of modernization. In December 1953, Comrade Mao Zedong initially put forward the idea of realizing the four modernizations. With the continuous enrichment and development of knowledge and practice, at the first meeting of the Third National People’s Congress held from the end of 1964 to the beginning of 1965, Comrade Zhou Enlai officially announced to the people of the whole country the strategic goal of realizing the "four modernizations" of agriculture, industry, national defense and science and technology. The strategic goal of "four modernizations" has clearly outlined the grand blueprint of China’s modernization for the first time and pointed out the direction of struggle for the people of the whole country. In order to realize the strategic goal of "four modernizations", the CPC Central Committee put forward two steps of development: "The first step is to establish an independent and relatively complete industrial system and national economic system; The second step is to fully realize the modernization of agriculture, industry, national defense and science and technology, so that China’s economy will be at the forefront of the world. " Through unremitting efforts, by the end of 1970s, China had achieved the first stage goal of two steps, which "laid a solid material foundation and created a reliable forward position" for China’s development.

　　After the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, the Party and the country rose again from the crisis, but it is not easy to achieve the strategic goal of "four modernizations" at the end of the 20th century. Comrade Deng Xiaoping pointed out that "now we have to seek truth from facts in order to realize the four modernizations". With the practice of creating a new situation in reform, opening up and socialist modernization, in March 1979, Comrade Deng Xiaoping first put forward the concept of "four modernizations in Chinese style", and at the subsequent retreat of the party’s theoretical work, he further pointed out that "the democratic revolution in the past should be suitable for China’s situation" and "the construction now should also be suitable for China’s situation and embark on a Chinese modernization road". In December of the same year, Comrade Deng Xiaoping used "a well-off family" to describe the development goal of Chinese modernization for the first time when meeting foreign guests.

　　According to Comrade Deng Xiaoping’s strategic vision, the Twelfth National Congress of the Communist Party of China formulated the goal and strategic deployment of "people’s material and cultural life reaching a well-off level" by the end of the 20th century. The 13th National Congress of the Communist Party of China clearly made a "three-step" development strategic arrangement. Through the hard work of the whole party and people, in 1997, China achieved the first and second steps of the "three-step" strategic goal ahead of schedule. Subsequently, the 15th National Congress of the Communist Party of China further concretized the third step of the "three-step" strategic goal and put forward three phased goals. The 16th National Congress of the Communist Party of China officially declared that people’s life has reached a well-off level on the whole, and put forward the goal of building a well-off society at a higher level that benefits more than one billion people in the first 20 years of the 21st century. The 17th National Congress of the Communist Party of China put forward new and higher requirements for the goal of building a well-off society in an all-round way. The 18th National Congress of the Communist Party of China adjusted "building a well-off society in an all-round way" to "building a well-off society in an all-round way", and put forward the grand goal of ensuring building a well-off society in an all-round way by 2020, which pointed out the direction for accelerating socialist modernization.

　　China has embarked on a new journey of building a socialist modern country in an all-round way.

　　Since the 18th National Congress of the Communist Party of China, Socialism with Chinese characteristics has entered a new era. The CPC Central Committee with the Supreme Leader as the core scientifically summed up the practical experience of China’s socialist modernization, constantly promoted the practical development of Chinese modernization, constantly expanded the rich connotation of Chinese modernization, and opened up a new realm of comprehensively promoting the great rejuvenation of the Chinese nation with Chinese modernization.

　　In the new era of ten years, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the whole party, the whole army and the people of all ethnic groups throughout the country have worked in unity to overcome difficulties, and pushed forward Socialism with Chinese characteristics in the new era with a spirit of hard work, providing a more perfect institutional guarantee, a more solid material foundation and a more active spiritual force for realizing the great rejuvenation of the Chinese nation. In this decade, we are celebrating the centenary of the founding of the Communist Party of China (CPC). Push Socialism with Chinese characteristics into a new era; Accomplishing the historical task of getting rid of poverty and building a well-off society in an all-round way, and realizing the goal of the first century, the United struggle of the people of the Communist Party of China (CPC) and China won a historic victory that stood out in the history of the development of the Chinese nation and had a far-reaching impact on the world. In the past ten years, we have fully implemented the Party’s basic theory, basic line and general plan, adopted a series of strategic measures, promoted a series of revolutionary practices, achieved a series of breakthrough progress, achieved a series of landmark achievements, founded the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, comprehensively strengthened the Party’s leadership, made scientific and complete strategic arrangements for the development of the Party and the country in the new era, and realized the Millennium dream of a well-off society as a Chinese nation. Put forward and implement new development concepts, comprehensively deepen reform with great political courage, implement a more proactive opening strategy, adhere to the road of political development in Socialism with Chinese characteristics, establish and adhere to the fundamental system of Marxism’s guiding position in the ideological field, thoroughly implement the people-centered development thought, and adhere to Lucid waters and lush mountains are invaluable assets’s concept.Implementing the overall concept of national security, establishing the party’s goal of strengthening the military in the new era, comprehensively and accurately promoting the practice of "one country, two systems", comprehensively promoting the diplomacy of a big country with China characteristics, and deepening the comprehensive and strict administration of the party, etc., the party and the state have made historic achievements and undergone historic changes, pushing China to embark on a new journey of building a socialist modern country in an all-round way.

　　The great achievements of the decade in the new era were achieved under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, under the scientific guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, and through joint efforts of the Party and the people. Practice has fully proved that the "two establishment" is the most significant political achievement in the new era, the decisive factor to promote the historic achievements and changes in the cause of the party and the state, and the greatest certainty, confidence and guarantee for the party to deal with all uncertainties. In the new era and journey, to push forward the cause of Socialism with Chinese characteristics and promote the great rejuvenation of the Chinese nation in an all-round way with Chinese modernization, the most important thing is to deeply understand the decisive significance of "two establishment", strengthen "four consciousnesses", strengthen "four self-confidences" and achieve "two maintenance", and consciously maintain a high degree of consistency with the CPC Central Committee with the supreme leader as the core.

　　The fundamental follow-up to comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization

　　In the great practice of the new era, with a broad international vision, a lofty strategic vision and a firm mission, General Secretary of the Supreme Leader made profound thinking and scientific judgment on major theoretical and practical issues of Chinese modernization, put forward a series of original new ideas, new ideas and new strategies, and formed a series of important expositions of General Secretary of the Supreme Leader on Chinese modernization.

　　The first is the China characteristics of Chinese modernization.. This is: Chinese modernization is a modernization with a huge population; Chinese-style modernization is the modernization of common prosperity for all people; Chinese modernization is a modernization in which material civilization and spiritual civilization are coordinated; Chinese modernization is the modernization of harmonious coexistence between man and nature; Chinese modernization is the modernization that takes the road of peaceful development. In the world, there is neither a model of modernization based on one respect nor a universal standard of modernization. Chinese-style modernization is the socialist modernization led by the Communist Party of China (CPC), which has both the common features of modernization in all countries and the characteristics of China based on its own national conditions. General Secretary of the Supreme Leader pointed out: "China is the largest socialist country in the world. When China becomes the first socialist modernization power in the world, it will take the socialist road instead of the capitalist road to successfully build a modern power. The great social revolution led by our party in China will more fully demonstrate its historical significance."

　　The second is the essential requirement of Chinese modernization.. That is, adhere to the leadership of the Communist Party of China (CPC) and Socialism with Chinese characteristics, achieve high-quality development, develop people’s democracy in the whole process, enrich people’s spiritual world, achieve common prosperity for all people, promote harmonious coexistence between man and nature, promote the construction of a community of human destiny and create a new form of human civilization. This summary is concise and rich in connotation, which emphasizes the fundamental requirements of adhering to the leadership of the Party and the Socialism with Chinese characteristics system, covers the goal of prosperity, democracy, civilization, harmony and beauty, and also highlights the world significance and contribution of Chinese modernization.

　　Third, the major principles that must be firmly grasped in promoting Chinese modernization.. That is, to uphold and strengthen the Party’s overall leadership, adhere to the Socialism with Chinese characteristics Road, adhere to the people-centered development thought, persist in deepening reform and opening up, and persist in carrying forward the spirit of struggle. To ensure the socialist direction of modernization, the most fundamental and crucial thing is to uphold and strengthen the overall leadership of the party; To promote Chinese-style modernization, we must stick to the same goal and road, neither take the old road of being closed and rigid, nor take the evil road of changing the flag, and always follow the road of Socialism with Chinese characteristics; The essence of modernization is people’s modernization, people are the main body to promote modernization, and realizing people’s yearning for a better life is the starting point and the end result of modernization. From solving the problem of food and clothing to overall well-off society and then to overall well-off society, we have come to this day step by step through reform and opening up. In the future, we will basically realize socialist modernization and build a socialist modernization power in an all-round way, and we still have to rely on reform and opening up to become a reality step by step; Promoting Chinese-style modernization is not a smooth road, and it will not be smooth sailing. This requires carrying forward the spirit of struggle, enhancing the skills of struggle, rallying the will and strength of the whole party and people, and overcoming all foreseeable and unpredictable risk challenges. The five major principles, which condense the valuable experience of the party and the people in their long-term struggle, embody the party’s basic theory, line and strategy, and are major issues related to the overall situation of socialist modernization.

　　General Secretary Supreme Leader’s series of important expositions on Chinese-style modernization further profoundly answered the topic of "what kind of socialist modernization power to build and how to build a socialist modernization power", which is a scientific summary of China’s long-term exploration and practice of socialist modernization, a significant enrichment and development of world modernization theory, and an important part of Supreme Leader’s Socialism with Chinese characteristics Thought in the new era.

　　Under the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, the 20th National Congress of the Communist Party of China, on the basis of the "two-step" strategic arrangement for building a socialist modernized country in an all-round way made by the 19th National Congress of the Communist Party of China, further made a macro outlook on the development goals in 2035 and the middle of this century, made key arrangements for the strategic tasks and major initiatives in the critical period of building a socialist modernized country in an all-round way in the next five years, and clearly outlined the timetable and road map for continuing to promote Chinese modernization in the new era.

　　General Secretary Supreme Leader’s series of important expositions on Chinese modernization are the theoretical support for the strategic layout of building a socialist modernized country in an all-round way, and the strategic layout of building a socialist modernized country in an all-round way is the practice of this theory. In the magnificent historical process of integrating theory with practice, building a socialist modern country in an all-round way will surely write a new glorious chapter.

　　The great significance of the innovation breakthrough of Chinese modernization in the new era

　　The Chinese-style modernization road is a modernization road that not only conforms to the reality of China, but also embodies the law of socialist development and the law of human society development. It has written its own modern civilization and made great achievements that attract worldwide attention.

　　Chinese-style modernization has opened up a brand-new road for the governance of socialist countries and made scientific socialism glow with great vitality in China in the 21st century. General Secretary of the Supreme Leader pointed out: "In fact, how to govern a brand-new society like a socialist society was not well solved in the past world socialism." In the new era, the CPC Central Committee with the Supreme Leader as the core has made Socialism with Chinese characteristics’s system mature and stereotyped, advanced the modernization of the national governance system and governance capacity, achieved unprecedented theoretical achievements, practical achievements and institutional achievements, and embarked on a new road to solve the world socialist problem of national governance.

　　Chinese-style modernization has expanded the way for developing countries to modernize. The General Secretary of the Supreme Leader pointed out: "To govern a country and promote a country’s modernization, there is not only the western system model, but all countries can go out of their own way." The diversity of historical conditions and realistic national conditions determines the diversity of development paths chosen by countries. In the process of human modernization, there are no more than 30 industrialized countries with a population of no more than 1 billion. Moreover, the modernization of these countries is mostly based on the primitive accumulation of bloody foreign colonial plunder and cruel exploitation of people at home, and it took more than 200 years to reach the current level. Chinese-style modernization is the modernization of a late-developing country. The pace of building modernization and catching up with the times in a developing country with relatively backward economy and culture is doomed to make it impossible for us to keep pace with the development of modernization in western developed countries. Under the leadership of the Party, we have taken advantage of our backwardness, based on the reality of China, adhered to independence and eclecticism, embarked on a new road of Chinese modernization, and provided new choices for those countries and nations in the world who want to accelerate their development and maintain their independence.

　　Chinese-style modernization has contributed China’s wisdom and China’s plan to solving human problems. Chinese modernization pays attention to the future and destiny of mankind, and advocates working hand in hand with all progressive forces in the world to develop itself and benefit the world. China’s successful road to modernization of "being strong but not hegemonic" has proved to the world with practical actions that a strong China is not a threat to world peace, but the backbone of maintaining world peace and promoting world development. Along the road of Chinese modernization, China, together with all peace-loving countries and people, actively promotes the construction of new international relations, the building of a community of human destiny, the high-quality development of the "Belt and Road", the promotion of the common values of peace, development, fairness, justice, democracy and freedom of all mankind, the contribution of China wisdom, China’s plan and China’s strength to solving human problems, and the new and greater contribution to creating a better future for human society.

　　Chinese modernization is a great and arduous undertaking. Only it is arduous, so it is great; Only it is arduous and more glorious. On the new journey, we must unite more closely around the CPC Central Committee with the Supreme Leader as the core, fully implement the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, always maintain a high-spirited and enterprising spirit, be firm in our determination to remain unchanged, adhere to the Socialism with Chinese characteristics road, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization. We will certainly be able to complete the historical ambition of building a socialist modern country in an all-round way, create new achievements worthy of the party, the people and the times, and win even greater victories and victories.

The proportion of B flow continues to rise! Adults and children have been recruited one after another, and some people call it ＂pain in the bones.＂

After mycoplasma pneumonia and swine flu

Recently, B-stream has attracted public attention again.

Some people are online.

I shared the process of my cold and fever:

Persistent high fever

Muscle and joint aches all over the body.

Continued fatigue after turning negative.

Some netizens also said:

"B flow is Wang Zhongwang.

It hurts all over the body until it hurts in the bones. "

01

B-stream is on the rise in both north and south.

The weekly report of the 52nd week of 2023 (from December 25th, 2023 to December 31st, 2023) released by the National Influenza Center of China on January 4th shows that although influenza A is still the main stream, the proportion of influenza B is rising, and it has been rising for nine consecutive weeks in the north, from 4.2% in the 44th week to 47.3% in the 52nd week. South China has been rising for six consecutive weeks, from 11.6% in the 47th week to 26.4% in the 52nd week.

Source: China News Network

02

What are the symptoms of B-stream?

1. Simple type: There will be high fever, headache, fatigue, loss of appetite and other manifestations, and a few may have symptoms such as cough, stuffy nose, dry throat and hoarseness. Generally, the body temperature reaches the highest value in 1 ~ 2 days, gradually decreases in 3 ~ 4 days, and the symptoms gradually improve after fever.

2, gastrointestinal type: mainly manifested as vomiting, abdominal pain, diarrhea, loss of appetite and other manifestations.

3. Pneumonia type: The patient has persistent high fever, shortness of breath, cyanosis, hemoptysis, extreme fatigue and even respiratory failure.

4, poisoning type: high fever, convulsions and other systemic toxemia may occur, and in severe cases, shock or even death may occur.

Compared with A-stream, B-stream usually has a smaller outbreak range and a lighter illness. For some mild patients with strong immunity and good health, they can recover on their own.

Why does infection with B-stream hurt in the bone seam?

In fact, some people have bone headaches, whether in COVID-19 before, or in A-stream and B-stream.

Lin Hua, deputy chief physician of the Department of Respiratory Medicine, Xiangya Third Hospital, Central South University, said that patients with upper respiratory tract infectious diseases caused by rhinovirus, adenovirus, influenza virus and other pathogenic bacteria may have systemic aches and fatigue.

When pathogenic bacteria enter the body, it will destroy immunity and release inflammatory mediators, such as prostacyclin, which will spread all over the body with blood circulation. When used in bones, it will lead to bone headaches for patients. In addition, pathogenic bacteria can cause skeletal muscle spasm and contraction. If it stimulates the peripheral central nervous system, some patients will also have a bone headache, so they will have a bone headache.

03

What’s the difference between stream B and stream A?

Influenza (including influenza A and B) mainly manifests as systemic symptoms, such as high fever and sore muscles, while respiratory symptoms such as runny nose and cough will be lighter. Fever is persistent, and it often burns again after taking antipyretics for a few hours.

influenza A virus

influenza B virus

incubation period

1~3 days, up to 7 days.

Usually 1~4 days.

temperature

The body temperature is high, generally exceeding 39 C.

High fever persists, exceeding 39 C.

symptom

Muscle ache accompanied by dizziness, headache, diarrhea, vomiting and other symptoms or some of them, respiratory symptoms are mild or not obvious.

Mental malaise, mild respiratory symptoms, dry throat, sore throat, dry cough and other symptoms, sometimes accompanied by vomiting and diarrhea.

It should be reminded that there is little difference between the symptoms of A stream and B stream, so it is difficult to distinguish them according to clinical manifestations, and it is still necessary to cooperate with tests to diagnose them.

At the same time, I would like to remind you that B-stream is caused by virus. Antibiotics such as penicillin and cephalosporin we usually use are drugs against bacteria, which are useless for B-stream. Therefore, it is not recommended that you use antibiotics without authorization when you have a fever.

04

Don’t put off two things after being infected with B stream.

1. Take anti-influenza drugs as soon as possible, and don’t delay.

There is no difference between B stream and A stream in treatment, mainly using anti-influenza drugs, which can shorten the course of disease. Take the medicine as soon as possible. If you take it late, you will either get well or turn into a serious disease, and the curative effect will be greatly reduced.

Blocking virus replication at the early stage of flu symptoms has the best effect, and antiviral treatment within 48 hours can get the best effect. More than 48 hours after gold, antiviral drugs can also benefit. It is recommended to take the medicine according to the doctor’s instructions.

Note: Patients with pulmonary diseases or immunodeficiency, diabetic patients, obese patients, pregnant women, including dialysis patients, etc., are advised to go to the hospital as soon as possible.

2. Be sure to rest in time, don’t put it off.

In December 2023, a 14-year-old B-stream patient admitted to a hospital in Zhejiang Province, in just over a month, she "rotated" mycoplasma pneumonia, A-stream and B-stream. The doctor said that repeated infection with mycoplasma, A stream and B stream in a short period of time is related to low immunity and failure to recover from rest.

In addition, the measures to prevent influenza are basically the same as those to prevent COVID-19, such as avoiding going to crowded and closed places; The home environment should be ventilated frequently; Wear a mask when going out, wash your hands frequently, etc.: "We must continue to do a good job of protection, and we must not relax our vigilance." ▲

Cangzhou CDC influenza network laboratory

The first batch of influenza virus isolated from chicken embryos was successfully obtained.

The influenza network laboratory of the Municipal Center for Disease Control and Prevention has set up a number of sentinel sites in major hospitals in our city, which belongs to the national influenza detection network and undertakes the task of detecting and reporting influenza viruses in our city. Since 2017, the laboratory has used influenza viruses extracted from major hospitals to carry out the experiment of "isolating influenza viruses by chicken embryo culture" to provide antigens for the development of national influenza vaccines.

Recently, in the first batch of influenza virus isolation work of 100 eggs, they successfully obtained the strain and sent it to the provincial CDC. Now, they are involved in the new influenza virus isolation work, carefully cultivating the second batch of 50 eggs.

Original title: "The proportion of B flow continues to rise! Adults and children have been recruited one after another, and some people call it "pain in the bones".

Micro-observation of current politics ｜ The future of a country lies in the youth.

　　"Youth is like early spring, like the morning sun, like the germination of flowers, like the new development of a sharp sword, and the most precious period of life."

　　More than a hundred years ago, Youth Magazine was founded and later renamed New Youth, which had a far-reaching influence. In that stormy era, a group of new youths held high the torch of Marxist thought and searched hard for the future of national rejuvenation.

　　For more than 100 years, China has never stopped exploring the road of modernization. General Secretary of the Supreme Leader pointed out that the Chinese dream of realizing the great rejuvenation of the Chinese nation cannot be separated from the relay struggle of generations of young people.

　　On June 22nd, the 19th National Congress of the Communist Youth League of China was successfully concluded. The General Assembly mobilized and led the youth members to unite and struggle for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way.

　　It will take one or two generations to achieve the goal of the second century from now until the middle of this century. General Secretary of the Supreme Leader emphasized that the young people of China in the new era are born at the right time and shoulder heavy responsibilities.

　　What kind of young people can be so responsible? What would they look like if they painted portraits of new youth in the new era?

　　— — The appearance of fighting bravely for the first place.

△ On June 19th, 2023, local time, UNESCO held the first "Al-Fazan Award" awarding ceremony at its Paris headquarters, and China scientist Fu Qiaomei was awarded the award.

△ On June 19th, 2023, local time, UNESCO held the first "Al-Fazan Award" awarding ceremony at its Paris headquarters, and China scientist Fu Qiaomei was awarded the award.

　　On June 19th, Fu Qiaomei, a researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, was awarded UNESCO — Al-Fazan International Award for Outstanding Young Scientists in Science, Technology, Engineering and Mathematics.

　　Fu Qiaomei has been engaged in paleogenetics research for a long time, mainly focusing on ancient DNA to explore important scientific issues of human origin and evolution. As one of the leading scientists in the field of international paleogenetics, Fu Qiaomei stood out from 2,500 candidates around the world and became the first China scientist to win this prize.

△ On September 11th, 2020, General Secretary of the Supreme Leader listened to the speeches of seven representatives of scientists, including Fu Qiaomei.

△ On September 11th, 2020, General Secretary of the Supreme Leader listened to the speeches of seven representatives of scientists, including Fu Qiaomei.

　　"People often ask, ‘ What’s the use of your research ’ . When it was difficult to maintain the laboratory, I also thought about whether to do hot research. " In September, 2020, when talking with the General Secretary of the Supreme Leader, Fu Qiaomei expressed her confusion.

　　The general secretary said: "What do you think of the unpopular? Generally speaking, some unpopular things are useless. This understanding may delay the career in a field. To evaluate scientific research, we must have a long-term vision, a world vision and a scientific vision. "

　　Fu Qiaomei was deeply inspired. She led a young team and made continuous breakthroughs in research, pushing China’s ancient DNA research into the forefront of the world.

　　A generation has the fate of a generation, and a generation of young people has the mission of a generation of young people.

　　On May 4, 2013, General Secretary of the Supreme Leader came to China Academy of Space Technology of China Aerospace Science and Technology Corporation to participate in the theme group day.

　　After 90′ s, Pei Xianfeng became a skilled welding technician in just a few years through diligent study and hard practice, and won the silver medal in the welding project in the World Skills Competition, achieving a breakthrough of zero medals in Chinese.

　　The general secretary praised: "through hard work, your youth career is highly compatible with the cause of the party and the country and the cause of the people, so that the spectrum of your career will be broader and the energy will be stronger."

△ At 13: 30 on June 15th, 2023, the Long March II D carrier rocket successfully launched 41 satellites, including Jilin No.1 high-scoring 06A star, into the scheduled orbit, setting a new record for multiple satellites with one arrow in China.

　　"Mozi", "Tian Wen" and "Chang ‘e", young scientific and technological talents can be seen everywhere in these undertakings entrusted with the dream of national rejuvenation — — The average age of the core staff of Beidou satellite team is 36 years old, the average age of quantum science team is 35 years old, and the average age of Five-hundred-meter Aperture Spherical Radio Telescope (FAST) FAST R&D team is only 30 years old … …

　　The General Secretary of the Supreme Leader encouraged: "We should look at the innovation and creation of young people with appreciation and approval, actively support them to shine in life, and praise and applaud the achievements and achievements of young people."

　　— — Not afraid of hardship

　　Do you choose a stable life in Beijing, or do you choose to go back to the countryside to "suffer"?

　　Wei Qiao, a young man born in 1980s, gave her own answer: She used to be an assistant researcher at the Institute of Geography of China Academy of Sciences. Six years ago, she and her husband both quit their jobs in the Chinese Academy of Sciences and Peking University, and returned to their hometown in Jiangsu to plant more than 20,000 mu of rice. Through digital management, the yield per mu reached 1,100 Jin, which effectively promoted the surrounding farmers to become rich.

△ On March 5, 2023, General Secretary of the Supreme Leader participated in the deliberation of the Jiangsu delegation of the First Session of the 14th National People's Congress.

△ Wei Qiao spoke at the plenary session of the Jiangsu delegation at the First Session of the 14th National People's Congress.

△ Wei Qiao spoke at the plenary session of the Jiangsu delegation at the First Session of the 14th National People’s Congress.

　　During the National People’s Congress this year, Wei Qiao told the Supreme Leader General Secretary about his experience. After hearing this, the general secretary was very appreciative: "It’s good for a comrade like Wei Qiao to go to the countryside!"

　　Suffering hardships is also the choice of the supreme leader in youth. In Liangjiahe, Shaanxi Province, farming, pulling coal, damming and picking dung … … He has done almost everything. Looking back on those days, he wrote in "I am the Son of the Yellow Land", "Difficulties and hardships can temper a person’s will. The hard life of going to the countryside for seven years was a great exercise for me. Later, when I encountered any difficulties, I remembered that I could still work under such difficult conditions at that time. Why not do it now? "

　　In Zhengding, Hebei Province, he rode his bicycle all over every village in the county, got a solid and detailed understanding of the county situation, found problems and collected public opinion. He said that he was ready to enter the "sea of suffering"; In Xiamen, he volunteered to take charge of the work concerning agriculture, rural areas and farmers, and made full use of all forces to promote the development of poverty-stricken areas … …

　　Today, the young people in China in the new era are in the best period of the development of the Chinese nation, and they are faced with the rare life opportunity of making great achievements, as well as the mission of the times.

　　In youth, if you choose to suffer, you choose to gain, and if you choose to give, you choose to be noble.

　　When inspecting the Youth Cave in Hongqi Canal, Anyang, Henan Province, the General Secretary emphasized: "The younger generation should inherit and carry forward the spirit of hard work, self-reliance and hard struggle, abandon arrogance and arrogance, and engrave their youthful blood on the historical monument like our parents."

　　In a reply to the students in the Science and Technology Academy of China Agricultural University, the General Secretary encouraged everyone: "You said in your letter that only when you go deep into the local China can you deeply understand what is seeking truth from facts and how to contact the masses, and young people will ‘ Ask for it ’ That’s very good. China youth in the new era should have this spirit. "

　　Just as General Secretary of the Supreme Leader said in a discussion with outstanding youth representatives from all walks of life ten years ago, "It is good for you to experience a little more beatings, setbacks and tests in your youth."

　　— — Aim high.

△ On February 15th, 2022, Su Yiming, a player from China, won the men's grand platform championship of snowboarding in Beijing Winter Olympics.

△ On February 15th, 2022, Su Yiming, a player from China, won the men’s grand platform championship of snowboarding in Beijing Winter Olympics.

　　Su Yiming, who won the championship in Beijing Winter Olympics, wrote a letter to the Supreme Leader General Secretary after the game.

　　Soon, he received a reply from the general secretary — — "I hope that your hearts are tied to the motherland, your ambitions are high, your feet are on the ground, you will create a wonderful life in your struggle and contribute your youth and strength to the motherland and the people."

　　The paper is short-lived and long-lasting, and the hope is infinite. Youth’s ideals and beliefs are related to the future of the nation.

　　In July, 2021, Huang Haifen, a Chaoshan girl born after 1990s, met the Supreme Leader General Secretary who was investigating in Xizang. At that moment, her heart was pounding with excitement: "I am a university student village official. I graduated from Guangdong University of Finance and Economics four years ago and always wanted to do something for the frontier, so I came to work in Linzhi."

　　The general secretary asked with concern: "Will you stay here in the future?"

　　Huang Haifen said shyly, "Stay! Settle down, my lover is in the next village and came to Xizang together. "

　　The general secretary encouraged her: "From the coast to the plateau, people are needed here. You should do well here."

　　Hearing the general secretary’s words, Huang Haifen nodded with tears in his eyes.

　　A life with faith, dreams, struggle and dedication is a meaningful life. Generation after generation of young people have integrated their "small goals" into the "big blueprint" of the cause of the party and the country.

　　"In the new era, young people in China should establish their belief in Marxism, Socialism with Chinese characteristics and the Chinese nation’s great rejuvenation of the Chinese dream, go among the people and go to a new era and a new world, so that ideals and beliefs can be sublimated in entrepreneurial struggle and youth can shine in innovation and creation!" This is the ardent expectation of the Supreme Leader General Secretary to the contemporary youth at the conference commemorating the centenary of the May 4th Movement.

Looking at power consumption through inductance loss, the calculation is not complicated at all.

Address quoted in this article: https://www.eepw.com.cn/article/201706/346888.htm.

one, overview

The power consumption of power supply is various, including switching loss, input/output capacitance loss, static power consumption of controller and. This paper mainly introduces the simple calculation. Including two aspects: one is the loss related to the magnetic core, that is, the traditional iron loss; The second is the loss associated with the inductor winding, which is commonly called copper loss.

Total Power Dissipation（W）= CopperLoss + CoreLoss

CopperLoss = IRMS2*RDC(mΩ )/1000

CoreLossGenerally, it is obtained by checking the manufacturer’s form.

2, calculation method

Take Pulse’s PA1513NL series inductor as an example, and adopt PA1513NL.321NLT. The datasheet downloaded from official website is as follows. The basic parameters are: the inductance is 320nH, and the DC resistance is 0.53 11.3%.

In the design, we use this resistor in the switching frequency of 600kHz and the load current I.LOADIn the BUCK circuit of 30A, where iripple = 30% * i.LOAD.

According to the above formula, it can be easily calculated that the maximum copper loss is:

CopperLoss = IRMS2* RDC(mΩ )/1000 =（30A）2 *(0.53*111.3% mΩ ）/1000 = 0.531W

Regarding the maximum iron loss, we must first calculate △B: (because the inductance error is a curve, we use the normal value to calculate it).

△B = .23* L(nH)* △I = 0.23 * 320（nH）* 30% * ILOAD = 662.4

Since the switching power supply works at a frequency below 600KHz, the iron loss can be found to be about 0.18W by looking up the table.

Then the total loss is as follows:

Total Power Dissipation（W）= CopperLoss + CoreLoss = 0.711W

By looking up the table, we can get that the temperature rise of the inductor is about 45 degrees Celsius under normal working conditions.

The main functions of evaluating the loss of inductance are: first, to see whether the loss of inductance will cause the overheating of inductance, which will lead to the decrease or even damage of inductance value; The second function is to adjust the parameters of inductance and improve the efficiency of the whole power conversion system.

threeAbout CoreLoss

In fact, the calculation method and curve of CoreLoss are not given on the datasheet of many inductance companies. If so, it is almost impossible to calculate the iron loss. In this case, there are two suggestions.

If this inductor is used in high-current and critical equipment, then please choose a supplier that provides iron loss, such as Pulse, Wurth, JW Miller, etc.

If the current is relatively small or the switching frequency is relatively low, the general iron loss is not the key factor. Then first evaluate whether the copper loss is OK, and leave a certain margin. If the inductance is overheated in the subsequent test, try to reduce the switching frequency of the power supply, or adopt an inductance with a smaller DCR.

Language is the key to the future.

　　As a symbol of the country and the nation, language is not only the hard power of the country’s development, but also the strong soft power of the country. The level of national language ability affects the overall strength of the country.

　　On the 14th, the 18th National Publicity Week for Promoting Putonghua was officially launched. This year’s theme is "Promoting Putonghua according to law and enhancing the country’s soft power". Its purpose is not only to mobilize resources from all aspects of society to actively participate in the popularization of the national common language, but also to apply them to many fields such as economy, society and culture. This activity also makes people further understand the importance of language and think about language problems.

　　"The reason why people are human is that they speak." Language is the basic tool for human beings to express their thoughts, acquire knowledge and communicate, and plays an important role as a bridge and link in our lives.

　　Language is the key to a country. When meeting with German sinologists, Confucius Institute teachers’ representatives and students’ representatives in Berlin in March 2014, the Chairman of the Supreme Leader pointed out that "the important tool of communication is language. The charm of a country’s culture and the cohesion of a nation are mainly expressed and transmitted through language. Mastering a language means mastering the key to a country’s culture. " Under the background of world multipolarization, economic globalization, cultural diversity and democratization of international relations, people-to-people communication plays an important role in cooperation between countries. Mastering different languages is conducive to effective communication, which enables people from different cultures, races and countries to know and understand each other in the process of feeling the profound connotation of different civilizations, thus narrowing the distance between people and countries and promoting the mutual tolerance and harmonious coexistence of world civilizations. Especially in the context of the current construction of the Belt and Road, it is as important as the interconnection of material civilization to promote the cultural exchange of countries along the Belt and Road with the exchange of languages, and then promote the "communication between the people".

　　Language is the key to wisdom. With the advent of internet plus, Industry 4.0 and new hardware era, science and technology such as big data, cloud computing, Internet of Things and mobile terminals have developed rapidly, and the intelligence of families, cities and society is getting higher and higher. In the past, many things that had to be done by hands can be easily done with a password or a button in the intelligent society. For example, to dial someone, just say the name of the other person and you can dial the phone; To buy a train ticket, just say the name of the place of origin accurately, and the self-service ticket vending machine will issue the ticket immediately; Turn off the electrical equipment at home, as long as you say the relevant password or verification code, the power will be cut off immediately … In the intelligent society, only universal, standard and standardized languages are effective, and the standardized construction and popularization of standardized languages are particularly important in our lives. It can be said that in the virtual space of the Internet, the effective expression of language plays a key role in the healthy operation of our smart home, smart city and smart society.

　　Language is the key to the future. In the future international competition, the language problem has risen from the general problem to the national level, and language has become a strategic weapon to safeguard national interests and security. As a productive force, language ability has also played a great role in promoting the development of language industry. Statistics show that there are about 1.2 million employees in China’s language industry, and the annual output value of translation and localization business is about 12 billion yuan. Facts show that the language industry has become a new growth point in the future economic development. Fully tapping and rationally utilizing the cultural and economic values of language resources, vigorously developing language resources and supporting the development of language industry will certainly provide new impetus for economic development while providing diversified language services for the society.

　　As a symbol of the country and the nation, language is not only the hard power of national development, but also the strong soft power of the country. The level of national language ability affects the overall strength of the country. The healthy development of language affects the future political, economic and cultural development of the country, and only by winning the future of language can we win the future of the country. We should re-recognize the function and function of language, and the whole society should pay more attention to language and development issues, vigorously strengthen the national and national language capacity building, build a language power, and enhance the soft power of the country. (Yao Xishuang, Director of the Language Application Management Department of the Ministry of Education)
