We all have to breathe, but what kind of breathing method is good for our health, have you ever thought about it? Learn the correct breathing methods, what methods does Chinese medicine have?

　　How can I learn to breathe correctly?

　　There are two key points. First, it is necessary to ease the inhalation, that is, when inhaling, it should be even and slow, and try to inhale deeply so that the gas can fill the alveoli. The second is to vomit hard and clean, so that all the waste can be discharged from the body and more gas can be exchanged. The most scientific breathing method is: "Breathe-stop (hold your breath for 10-20 seconds)-breathe", which can enhance the excitability of parasympathetic nerves and increase the number of bowel sounds, which is beneficial to digestion and absorption, thus benefiting health and longevity.

　　Another advocated breathing method is the "total breathing method" based on deep and long abdominal breathing, which gradually makes the muscle groups such as lungs, ribs and diaphragm move to the maximum extent when breathing, so that the air fills the lungs. Although you have to practice deliberately at first, the ultimate goal is to integrate into life, and all kinds of postures and movements are combined with breathing. This will better grasp the strength and rhythm of the body and improve efficiency. For example, when climbing a mountain by breathing, there will be no mountain symptoms such as headache; You can swing farther in golf. This breathing method can be practiced on the bus, when walking, during work, or in front of the trees in the park. Especially in the face of sudden negative situations, breathing can adjust body and mind and stabilize emotions in a timely manner.

　　In the fresh air outdoors, you can also take more deep breaths consciously. The specific method of breathing is to inhale slowly through the nostrils. During the inhalation, the chest is lifted, and the abdomen will bulge slowly, and then continue to inhale, so that the whole lung will be filled with air. At this time, the ribs will be lifted and the chest will be enlarged. This process usually takes 5-10 seconds, then hold your breath for 5-10 seconds, pause for 2-3 seconds, and start a new breath. Repeated practice will become a correct breathing method.

　　Long-term physical exercise can also improve breathing. For example, swimming can make people’s vital capacity as high as 5000-7000 ml; Far greater than the average person’s 3000-4000 ml; Long-distance running has the most obvious improvement on the maximum oxygen uptake; Push-ups can improve the muscle ability around the chest wall and increase the strength of respiratory muscles.

　　Chinese medicine teaches you to learn abdominal breathing.

　　"Breathing to the navel, longevity and harmony with the sky" is a high evaluation of abdominal breathing by health care experts. Ancient Chinese doctors have long recognized that abdominal breathing has the wonderful function of eliminating diseases and prolonging life, and created fitness methods such as "breathing", "turtle breathing", "qi sinking into the abdomen" and "fetal breathing". Sun Simiao, a famous doctor in the Tang Dynasty, especially praised abdominal deep breathing. He practiced the method of regulating qi every day between dawn and noon, lying on his back in bed. In the Ming Dynasty, Leng Qian, a health care expert, wrote a 16-character health care order in "Essentials of Aging": "When you inhale, you will lift it, and the qi will return to your navel; When you mention it, you will swallow, and you will meet with fire and water. " These 16-character secrets include three health-care training methods: lifting anus, swallowing body fluid and abdominal breathing, which are magic weapons for eliminating diseases, keeping fit and prolonging life.

　　Traditional Chinese medicine believes that the abdomen lives in the middle of the human body and is the place where many important meridians converge. Abdominal breathing, with the ups and downs of abdominal muscles, strengthens the operation of qi and blood, makes the human body in the best state of relaxation and freedom, and is also the best state of menstrual flow, which is very beneficial to physical and mental health.

　　Abdominal breathing method:

　　Inhale deeply, consciously feel that the whole chest and abdomen are full when inhaling, then exhale slowly, and try to spit out the air in your body when exhaling, feeling that your chest and abdomen are flat. Inhale with your nose and exhale with your mouth.

　　When doing abdominal breathing, you can stand, sit and lie down, and you can practice it anytime and anywhere, but lying in bed is the best way to practice. Lie on your back in bed, loosen your belt, relax your limbs, concentrate your thoughts and get rid of other thoughts. Put your right hand on your belly button and your left hand on your chest. When inhaling, expand the abdomen outward to the maximum extent and keep the chest still. When exhaling, contract the abdomen inward as much as possible and keep the chest still. Cycle back and forth, keep the rhythm of each breath consistent, and carefully experience the ups and downs of the abdomen together.

　　The specific exercise method is: supine, according to 5 ~ 6 times per minute, the abdominal wall bulges when inhaling through the nose, and sinks when exhaling through the mouth. Abdominal breathing exercises should vary from person to person, according to one’s ability. The key is to do one’s best in the range of abdominal depression when inhaling and exhaling, but we should not rush into it. We should start from shallow to deep, and exercise at our own discretion every time and every day. Generally, we should practice once every morning and evening for 10 minutes.

　　For people in good health, the breath holding time can be appropriately extended, and the breathing rhythm should be slowed down and deepened as much as possible. People who are in poor health can not hold their breath, but they should absorb enough gas. If body fluid overflows during breathing, it can be swallowed slowly.

　　Principles when doing abdominal breathing

　　First, breathe deeply, long and slowly.

　　Second, breathe through your nose instead of your mouth.

　　Third, breathe in and breathe in for about 15 seconds, that is, breathe in deeply (bulge your stomach) for 3-5 seconds, hold your breath for 1 second, then exhale slowly (retract your stomach) for 3-5 seconds, hold your breath for 1 second.

　　Fourth, do it for 5 ~ 15 minutes at a time, and 30 minutes is the best.

　　Fifth, people who are in good health can hold their breath for a longer time and try to slow down and deepen their breathing rhythm; If you are in poor health, you don’t have to hold your breath, but you should inhale enough and exhale thoroughly.

　　Practice 1 ~ 2 times a day, and you can choose sitting, horizontal, walking and running. Practice until it is slightly hot and sweaty, and try to bulge and retract the abdomen for 50 ~ 100 times. You can also help with your hands. If there is overflow of oral fluid during breathing, do not spit it out, but swallow it slowly.

　　Method for relieve dyspnea by massage

　　1. Touch your chest. Keep underwear, lie on your back, relax all over, press your palms against your breasts, put your fingers together, and touch your chest with your fingers. At the same time, your right hand rotates 50 times to the right and your left hand rotates 50 times to the left. Then rotate 50 times in the opposite direction. Note: This section can relieve chest tightness, angina pectoris, asthma and shortness of breath. However, if you don’t get better, even persistent chest symptoms such as crushing pain and dyspnea behind the sternum may be acute myocardial infarction for more than 30 minutes. Go to a big hospital for rescue.

　　2, palms overlap massage chest and abdomen. With the abdomen between the two breasts as the center, the palms overlap. First, put the right hand under it and rotate it clockwise for 50 turns, then change the left hand under it and rotate it counterclockwise for 50 turns. Repeat, push out and pull in, gradually expand the scope, and the action should be slow and powerful.

　　3. Take a deep breath and massage your chest and abdomen with your palms crossed. Press on the right flank with the palm of your right hand, and press on the left flank with the left palm. At the same time, lift and rub (Dabao, Qimen, Tianchi, Xiongxiang, Zhou Rong, etc.) with both hands to the chest (inhale deeply at the same time), and push the palms alternately, with the right hand pushing up (Zhongfu, Yunmen, Yufu, Xuanji, etc.) and the left hand pushing down (fake window). When inhaling, let the chest expand as much as possible and bulge slowly; When exhaling, make the chest as narrow as possible and the abdominal muscles contract. (Hold your breath for a moment) Breathe through the nose repeatedly for 1 minute. Inhale oxygen and exhale carbon dioxide, enhance vital capacity and improve heart and lung function.

　　4, alternating hands, patting the chest and rubbing the back. When sitting or standing, first slap the left chest with the palm of your right hand, and at the same time beat the left back with the backhand of your left arm, and then beat the back (body column, Feishu, Xinshu, etc.) for 1 minute with alternating hands.

　　However, what needs to be pointed out here is that massage is only a "technique" and a "method"; The "Tao" is not angry, emotional stability and so on.

　　Learn the above breathing methods to benefit your body more.

　

CCTV News:According to WeChat official account, Beijing Center for Disease Control and Prevention, Japan announced that it would start discharging nuclear polluted water from Fukushima into the sea on the afternoon of August 24th, which caused global concern and heated discussion. Many citizens in Beijing also started to snap up edible salt. Some citizens think that "iodized salt can prevent nuclear radiation", which is incorrect. Many citizens want to know whether iodized salt can prevent the accumulation of radioactive iodine in the thyroid gland, so as to protect the thyroid gland.

The purpose of iodizing salt in China is to prevent and treat iodine deficiency disorders. Because Beijing is an iodine-deficient area in the environment, iodization with salt can supplement iodine nutrition for the whole people safely, conveniently and for a long time, so as to avoid iodine deficiency affecting the health of residents. According to China’s "National Food Safety Standard Iodine Content of Edible Salt", the iodine content in iodized salt is 20-30mg per kilogram. In a nuclear pollution accident, radioactive iodine is mainly accumulated in the thyroid gland. In the early stage of the accident, it is necessary to take 100mg of "stable iodine" once, which is equivalent to taking 3-5kg of edible iodized salt once. The Dietary Guidelines for China Residents (2022) clearly states that "adults should not consume more than 5g of salt every day". If excessive intake occurs, it will cause serious burden to various organs of the human body, induce or aggravate cardiovascular and cerebrovascular diseases and chronic nephropathy, and even cause dehydration and even death in severe cases.

Therefore, it is not advisable to prevent nuclear radiation by eating iodized salt!

　　Xinhua News Agency, Tianjin, June 9 (Reporter Guo Fangda, Song Rui) Put up shelves, hang up the slogan of "Micro Store", and decorate small colored lights around to create an atmosphere … … As night falls, the RV camping park in Qihe Village, Zhongtian, Tianjin is gradually becoming lively.

　　"Every weekend night, there are more than 70 stalls in the park, and the goods are dazzling." Bin Chen, head of the camping park, said. This kind of market has low operating costs and flexible venues, and has become an exchange platform for many young people to display personalized creative products, hand-made and fashionable products.

　　Xu Yan, a 30-year-old "office worker", used her spare time to "micro-start a business" to run a small handmade jewelry business in a night market. Xu Yan told reporters that many friends around her couldn’t hold back and became "small bosses" in the night market.

　　The 14th Five-Year Plan for Cultural Development proposes to "promote cultural consumption in an all-round way, speed up the development of new cultural consumption patterns and develop night economy".

　　From traditional barbecue snacks to novel urban camping experience, the flow of people along the Tianta Lake, one of Tianjin’s landmark buildings, is increasing.

　　"New sports such as Frisbee and All-Armored Fighting are the key projects for our investment negotiation." Ma Teng, head of Tianta Lake camping night market project, said that consumers are not only satisfied with filling their stomachs, but also rich consumption scenes can attract more people.

　　A number of new formats, such as interactive drama catering and cultural teahouse, are one of the early adopters for young consumers. "Many young people regard their hobbies as ‘ Micro-entrepreneurship ’ The means not only enriches the service form, but also stimulates actual consumption. " Ma Teng said.

　　Before the meal, I extracted my identity from the blind box, interacted with the actors during the meal to become a "person in the play", and tasted the market culture of Tianjin from the play and the plate. The "a good play" of Tianjin Impression City Old Wharf Restaurant recently attracted many guests.

　　"Integration is the key." Jing Wong, project manager of Tianjin North Performing Arts Group’s Business (Cultural Travel) Development Center, said, "We tell about Tianjin’s food culture in the form of drama, and many viewers are very much looking forward to what kind of food they will eat in the drama. At the same time, through the live with the actors ‘ Dragging ’ Diners can enjoy a feast of sight, hearing and taste. "

　　The audience enjoyed the interactive drama "Old Wharf Inside and Outside the Play". (Xinhua News Agency)

　　One is consumption, and the other is employment. The relationship between night economic vitality and employment can be seen from the data.

　　Cloud Account (Tianjin) Sharing Economic Information Consulting Co., Ltd. provides flexible employment services such as industrial and commercial tax agency, income verification and settlement, commercial insurance protection, etc. for more than 84 million workers with new employment forms, and a considerable part of the settlement takes place at night.

　　"In May of this year, the number of settlement people in cloud accounts at night (from 20: 00 to 24: 00) accounted for 27% of the whole day, of which 24: 00 settlement people accounted for 6%, which was one of the peaks of the whole day." Yang Hui, chairman of the enterprise, believes that the continuous enrichment of new employment forms is just an echo of the emerging consumer demand.

　　The "pulse" of night consumption is inseparable from urban characteristics. For example, Datang City, Xi ‘an, relies on cultural tourism resources to build a business matrix along the street, and many catering and cultural and creative brands have settled in, which has formed a sustainable "culture+"block. Nanjing’s Qinhuai River, Confucius Temple, Ming City Wall, Jiangnan Gongyuan and other cultural resorts complement each other, forming a unique landscape with a thousand-year-old charm and modern commerce.

　　"The development of night economy needs a breakthrough ‘ One side of a thousand cities ’ Deeply cultivate new models, new scenarios and new formats. " Gao Nan, a professor at Tianjin University of Finance and Economics, believes that with the injection of diversified forces, the night consumption market in various places will become more prosperous, and more cities will find the development code of organic integration of night economy and urban culture.

　　The report on the implementation of monetary policy in China in the first quarter of 2023 issued by the People’s Bank of China said that there is no deflation in China’s economy at present, and there is no basis for long-term deflation or inflation in the medium and long term.

　　According to data recently released by the National Bureau of Statistics, in April 2023, the national consumer price (CPI) rose by 0.1% year-on-year and decreased by 0.1% quarter-on-quarter; The national producer price (PPI) decreased by 3.6% year-on-year and 0.5% quarter-on-quarter. The year-on-year increase of CPI continued to fall, hitting a new low in April since March 2021. How to treat the current domestic price situation correctly? What will be the next price trend?

　　Affected by many factors, prices are falling.

　　Careful consumers will find that with the blooming of spring, vegetables and fruits on the market are not only more abundant, but also more and more "close to the people", and the latest statistics also reflect this change. In April, a large number of fresh vegetables and fresh fruits were put on the market, and the prices dropped by 6.1% and 0.7% respectively. The production capacity of live pigs is sufficient, and the price of pork decreased by 3.8% due to the influence of off-season consumption.

　　Dong Lijuan, chief statistician of the Urban Department of the National Bureau of Statistics, said that in April, the market supply was generally sufficient, and consumer demand gradually recovered. The core CPI excluding food and energy prices changed from flat last month to 0.1%, up 0.7% year-on-year, and the increase was the same as last month.

　　Dong Lijuan analyzed that from the ring comparison, in April, the travel demand increased during the small holiday, and the transportation rental fees, air tickets, hotel accommodation and tourism prices all rose, with the increase rate ranging from 4.6% to 8.1%; Affected by the fluctuation of international crude oil prices, domestic gasoline and diesel prices both fell by 1.7%; Merchants cut prices to promote sales, and the prices of fuel cars, new energy cars and household appliances dropped by 1%, 0.9% and 0.6% respectively.

　　Zhang Xuewu, director of the Analysis and Forecast Division of the Price Monitoring Center of the National Development and Reform Commission, said that fresh vegetables, gasoline and diesel, and fuel cars together affected the CPI by about 0.9 percentage points, which was the main reason for the low CPI operation. In April, PPI decreased by 0.5% month-on-month and 3.6% year-on-year. Zhang Xuewu believes that due to the international tension last year, the central banks of cardinal utility, the United States and Europe continued to raise interest rates, which led to the slowdown of economic growth and the financial risk spillover of some major developed economies. The international commodity price volatility was weak and had an import impact on China.

　　Xiong Yuan, chief economist of Guosheng Securities, believes that the recent decline in China’s prices is due to various factors such as the decline in pork prices, the slow recovery of service prices, and the weakening of commodity prices.

　　Zhang Xuewu said that the current downward trend of prices is mainly caused by the disturbance of high base, which is staged and temporary, and should be treated objectively and rationally and analyzed comprehensively and accurately. On the one hand, due to the influence of import, seasonal factors and high cardinal utility, the prices of some commodities have fallen more, which is the main reason for the current CPI decline; Affected by international geopolitics and other input factors, PPI has declined, but these factors are temporary. On the other hand, at present, China’s demand has recovered rapidly, and the overall economy has rebounded. In the first quarter, China’s GDP increased by 4.5%, and the growth rate was 1.6 percentage points faster than that in the fourth quarter of last year. This year’s "May 1" holiday tourism consumption recovery momentum is very strong.

　　China’s economy has not experienced deflation.

　　Prices are closely related to people’s lives. Low prices mean less living expenses, which can reduce the pressure of life. However, the relatively low price movement has also caused some people’s concern. Is deflation coming?

　　The report of the People’s Bank of China clearly indicates that there is no deflation in China’s economy at present. Deflation mainly refers to the continuous negative growth of prices and the downward trend of money supply, which is usually accompanied by economic recession. China’s prices are still rising moderately, especially the core CPI is stable at about 0.7% year-on-year, M2 and social finance are growing relatively fast, and the economic operation continues to improve, which is not in line with the characteristics of deflation. In the medium and long term, China’s total economic supply and demand are basically balanced, monetary conditions are reasonable and moderate, residents’ expectations are stable, and there is no basis for long-term deflation or inflation.

　　Wang Yuanhong, deputy director of the Economic Forecasting Department of the National Information Center, said that at present, the overall price level in China has not yet declined generally and continuously, so there has not been deflation.

　　Zhong Zhengsheng, chief economist of Ping An Securities, said that China’s GDP deflator rose in the first quarter compared with the fourth quarter of last year, which confirmed that deflation is a false proposition. The GDP deflator is not only a weighted average of CPI and PPI, but also a more comprehensive and comprehensive indicator. The highlight of China’s economy in the first quarter was the tertiary industry, which was fully reflected in the GDP deflator.

　　Wang Jinbin, deputy dean of the School of Economics of Renmin University of China, believes that China’s economic development situation determines that deflation is impossible. China’s economic output gap is narrowing, which determines that there will be no deflation. Estimates of China’s potential economic growth rate are mostly in the range of 5.0%~6.0%, while the GDP growth rate in the first quarter is 4.5%, and the output gap is converging. Although the PMI index was below the critical point of 50 in April, the production index was 50.2%, which continued to be above the critical point, indicating that manufacturing production maintained expansion.

　　Guan Tao, global chief economist of Bank of China Securities, said that at present, China’s CPI and core CPI inflation levels are low, but there has not been a continuous decline in the overall price level and the money supply, and there has not been a negative economic growth, which does not meet the definition of deflation. Low inflation is only because China’s economy is in a recovery period, and the anti-inflation force is strong, and the force to promote price recovery is gradually accumulating strength. Although the recent year-on-year decline in China’s PPI reflects the fall of commodity prices in cardinal utility and the world, it does not conform to the definition of deflation.

　　Moderate price level provides space for expanding demand.

　　How long will the current price decline last? What will be the trend of price operation throughout the year? How to expand domestic demand and stabilize growth in the next step?

　　The report of the People’s Bank of China predicts that CPI will fluctuate within a narrow range at a low level in the coming months due to the influence of a high base. From May to July this year, CPI will remain low in stages, mainly due to the high base of CPI increase of about 2.5% in the same period last year. With the reduction of the base, especially the policy effect, the gap between supply and demand is expected to close. It is expected that the CPI center may rise moderately in the second half of the year and may rise to near the average level in recent years at the end of the year.

　　Guo Liyan, director of the Comprehensive Situation Office of China Macroeconomic Research Institute, said that the analysis of prices should not only look at the "shape" of the month, but also comprehensively look at the "potential" of the quarter and the year. In April, the overall domestic price level was in a reasonable range, and the relatively low operation was only a seasonal and temporary phenomenon, not a trend feature. At present, China’s economy has a solid foundation of "stability" and a strong momentum of "progress". The endogenous kinetic energy is constantly increasing, and the supply and demand sides are recovering towards equilibrium. In particular, the consumption of contact services has rebounded significantly, which has led to an increase in employment and income, and the upward trend of the economy will gradually show up in prices. Looking forward to the whole year, the overall domestic price level will fluctuate slightly and moderately within a reasonable range.

　　According to Wang Yuanhong, after calculation, the low point of CPI and PPI increase in the year is in the second quarter. With the gradual recovery of the economy and the weakening of cardinal utility, the CPI and PPI increase will gradually increase in the third and fourth quarters, and the annual price may show a "V-shaped" trend.

　　Zhong Zhengsheng believes that the economic recovery is reflected in the price breakdown data, but the kinetic energy of household consumption growth needs to be further consolidated, and the current price level can create a better environment for further efforts to stabilize the growth policy.

　　Guan Tao believes that it is necessary to combine the implementation of the strategy of expanding domestic demand with deepening the supply-side structural reform, giving play to the effectiveness of policies and stimulating the vitality of business entities.

　　Wang Yuanhong suggested that in the next step, we should continue to implement a proactive fiscal policy and a prudent monetary policy, maintain macro-policy control, strengthen coordination and cooperation of various policies, and give priority to restoring and expanding consumption. Through government investment and policy incentives, we will effectively promote the investment of the whole society, give play to the supporting role of exports in the economy, and promote the overall improvement of economic operation.

　　Wang Jinbin said that the core of China’s high-quality economic development is innovation. A moderate price level can avoid excessive investment, and resources will be concentrated in long-term innovation areas. The moderate price level also provides space for the macro-policy of expanding demand. He suggested that a number of policies should be introduced to boost consumer confidence, focusing on supporting the consumption of end products with long industrial chains, and supporting local governments to introduce policies to expand household consumption and enhance residents’ sense of acquisition and happiness, so as to further consolidate the important role of consumption in steady growth.

　　There are problems such as drug resistance and drug toxicity, and it is impossible to completely reverse the damaged bone — — There are still some defects in the conventional anti-bone resorption drugs and bone anabolic drugs that have been used at present. For the elderly with declining organ function, it is difficult to bear the whole course of treatment, which restricts the overall effect of conventional anti-osteoporosis treatment.

　　On the eve of the World Osteoporosis Day on October 20th, Professor Fan Shunwu, Director of Orthopedics of sir run run shaw hospital, and the research team of Professor Tang Ruikang from the Department of Chemistry of Zhejiang University published a research result in the international authoritative magazine JACS. Through a new nano-material, baking soda (sodium bicarbonate) can be adsorbed on the bone surface in a targeted way, which can inhibit osteoclasts and fundamentally prevent osteoporosis. The team proved that it can inhibit the bone destruction of osteoclasts safely and intelligently through the in vivo experiments of mouse osteoporosis model.

　　The "termite disease" that eats bones needs to be cured urgently.

　　Osteoporosis is a kind of senile bone disease with decreased bone density and bone quality due to various reasons. With the acceleration of social aging in China, its incidence rate is getting higher and higher. In 2018, National Health Commission released the epidemiological survey of osteoporosis in China for the first time. The results show that China is 40-mdash; The prevalence rate of osteoporosis in 49-year-old population is 3.2%, that in 50-year-old population is 19.2%, and that in 65-year-old population is 32%. The bone health problems of middle-aged and elderly people in China are serious, and the population with low bone mass is huge, especially women.

　　"Young people should also pay attention to early prevention. Unhealthy lifestyles such as unbalanced diet, long-term meditation, smoking and drinking, and too little sunshine will affect the accumulation of basic bone mass, and bone mass is more likely to be lost after entering middle-aged and elderly people. " Lin Xianfeng, the first author of the above research paper and the attending physician of the Department of Orthopaedics, Run Run Shaw Hospital of Zhejiang University, said that it is conservatively estimated that the population of osteoporosis in China is close to 90 million.

　　According to the existing research, the primary cause of osteoporosis is the abnormal activation of osteoclasts, and the "acid" secreted by osteoclasts is considered to be the key initial factor of osteoclasts’ bone destruction and a necessary prerequisite for their degradation of bone tissue.

　　"If human bones are compared to a big tree, then osteoclasts are termites in the big tree. Once the activities of termites become active for various reasons, even the towering trees will collapse due to long-term decay." Fan Shunwu explained.

　　At present, the main drugs for the treatment of osteoporosis in clinic can achieve the purpose of anti-bone absorption and promoting bone synthesis and metabolism by focusing on the biological regulation of osteoclasts or osteoblasts, which can slow down the loss of bone mass in the elderly to a certain extent, but there is no key initial step of killing the external acid environment formed by osteoclasts from the source.

　　"Therefore, the existing drugs cannot completely reverse the bone destruction that has occurred, and non-bone selective administration will also lead to off-target and other organ toxic side effects." Fan Shunwu said that this series of problems has led to the poor clinical treatment effect of osteoporosis.

　　After acid and alkali neutralization, it is made into "biological armor"

　　Amazingly, baking soda reacts with acid, consuming hydrogen ions and producing carbon dioxide — — The "acid-base neutralization reaction" that people can learn in middle school has been unlocked by the research team.

　　According to reports, although osteoclasts are the source of osteoporosis, many studies show that they can promote bone formation and blood vessel formation as "precursor cells" before acid secretion, so it is very important to accurately target and inhibit osteoclasts.

　　Based on the basic chemical principle of acid-base neutralization, the research team has packed nontoxic and harmless baking soda (sodium bicarbonate) into a safe nanocapsule (liposome), and loaded tetracycline with bone binding force on the surface to enable it to be targeted and adsorbed on the bone surface. When osteoclasts secrete acid to destroy bone tissue, they will immediately release sodium bicarbonate, inhibit the function of osteoclasts, and achieve the goal of fundamentally preventing osteoporosis.

　　Tang Ruikang explained that, generally speaking, after the baking soda alkaline liposome material enters the body, it will form an alkaline "biological armor" for the bone and maintain the acid-base balance of the local microenvironment of the bone.

　　Lin Xianfeng introduced that this armor is more like the "soft armor" in martial arts novels. It has no interference with ordinary cells, but it has intelligent and long-term defense effects on cells that actively attack bone tissue like osteoclasts.

　　Studies have fully confirmed that sodium bicarbonate liposome material can completely prevent osteoclasts of osteoporosis mice from secreting acidic substances and dissolving bones in animals, and it has been confirmed by a series of observation methods such as micro-CT that it can preventively prevent the loss of bone mass, so that the bone mass can be preserved to a nearly normal and healthy level.

　　"We also confirmed the safety of this study on non-acid-secreting cells (osteoblasts, chondrocytes, mesenchymal stem cells, etc.) in the main organs and bone tissues of mice." Lin Xianfeng said.

　　"The new intelligent material used in the research is not a scarce object. The key synthetic raw materials it uses, such as sodium bicarbonate, liposomes and tetracycline, are all safe substances that have been widely used in clinic for a long time." Fan Shunwu believes that this is a favorable condition for the results to be put into clinical application.

　　"This study has opened up a new idea for the treatment of osteoporosis with new nano-drugs through its precise and intelligent effect on osteoclasts." Lin Xianfeng said that on the whole, this study shows a good prospect of clinical transformation and follows the treatment concept of "from biology" that we have always admired.

Special feature of 1905 film network In the past week, the film circle has been very lively.filmExposeJing Bo RanandRonghao LiIn the tidbits of the set, the shapes of the two were also exposed. It is understood that the film was successfully filmed in Harbin in May.

Recently, the film also shot in Northeast China was announced to be successful, while the film also exposed the tidbits of Zhou Dongyu and Haoran Liu.

In fact, the two films are full of many things in common: they both involve crime themes, and the directors are both newcomers to meet the audience.Are these same elements just coincidences?

　

When we carefully observe the box office of Chinese movies in the past two years, we can find that among the top ten Chinese movie box offices in 2019, three works were directed by newcomers, especially the first and second.

　

In the top ten box office of Chinese movies in 2018, the works directed by newcomers accounted for almost half. On the contrary, those veteran directors who once led the market have not achieved the expected market results of their new works.

　

In today’s market, when the audience is waiting for the new director’s work to come out, it seems that they expect the new director to be like a "dark horse" and bring us freshness and changes.Tao Tao, a film critic, has served as a judge of many new director awards and activities.variousIt tells us that when he watched the works of young Chinese directors, he found that these directors were intentionally turning from the previous thinking of art films to the creative orientation of genre films.

　

Undoubtedly, these young directors, especially the post-80s directors, are bringing fresh blood to Chinese films with their own efforts.

Creative transformation of business types

Typing.This keyword is frequently mentioned in our interview.Due to the Beijing International Film Festival andShanghai International Film FestivalIt was postponed one after another, and the venture capital meeting of the FIRST Youth Film Festival became the first venture capital meeting in China to announce the project plan this year.According to official data, in this year’s FIRST Venture Capital Fair, the proportion of crime, fantasy, comedy and other types of films has been the highest in the past three years.

Although there are still many themes such as family and youth in the official proposals, in these works, most creators are no longer satisfied with telling a story of pure family and youth, but instead begin to explore the development of other types of elements and the upgrading of the author’s expression under this theme framework.

　

It can be seen that the creative thinking of young creators is changing in this era.

　

This change has the momentum that the back wave impacts the front wave. When we look back on the fifth and sixth generation directors, we can find that their first films have laid the foundation for their subsequent creation. Today, most of them are still interested in staying away from genre films and commercial film systems and paying attention to the artistic expression of the authors.

　

Of course, the possibility of change is mostly guided by the market.After the National Day in 2015, a group of new directors’ works were released together. At that time, many movies ended up with word of mouth and no box office, onlyXin YukunThe director’s first filmSurprised everyone.

At that time, it was predicted that the success of this film would bring more possibilities for subsequent types of films; Of course, some people lament that it may only become a successful orphan.

　

Five years have passed, and it has been proved that after the Labyrinth of the Heart, there have been many films in the market that combine comedy, crime and other elements.

　

In the venture capital unit of Shanghai International Film Festival last year, low-cost black suspense film projects were particularly favored by investors. According to Shen Yun, the judge of venture capital unit, such films may become the investment trend in the next few years, because they have established a bridge between the author’s expression and the market to some extent. When the realistic theme gradually becomes the mainstream of today’s market, this kind of realistic or magical realistic project with personal expression will naturally be welcomed by the market.

　

Kick for, the film marketing director of the FIRST Youth Film Festival, also told us that after the success of films such as Heart Labyrinth, they will receive some very imitative projects in recent years, which may be borrowed from the characters, story background and story structure, but it is difficult to see the special and stylized parts, which is an obvious change.

Wu, CEO of the film and television copyright trading platform "Yunlaiwu", also revealed to us that on this platform, the multi-line narrative structure is quite popular among young screenwriters, and the number of such scripts is also quite large.It can be seen that a number of small and beautiful works in the past have become popular in the market, which has also stimulated more young filmmakers to create similar themes.

　

The influence of the shadow complex

In the interview, Zhang Pu, director of Grey Monkey, never stinted on Quentin and guy ritchie. Wang Yichun’s and Dong Yue’s "Blizzard is Coming" do not shy away from paying tribute to them; Director Xin Yukun also draws lessons from and refers to the Korean crime theme … …

　

It can be seen that these young directors are all influenced by genre films in the world.

　

Tao Taolin told us that in his exchange experience with young directors, it was found that compared with the worship of Tarkovsky, antonioni, Bergman and other art masters by the fifth and sixth generation directors, the idols of these young directors have also changed.

　

"Compared with our predecessors, our generation has the honor to watch all kinds of master classics and genre masterpieces from all over the world in acquiring film knowledge, making Cohen Brothers, quentin tarantino, Park Chan-wook, Bong Joon ho, guy ritchie and other directors with strong styles become idols of a new generation of fans."

This group of directors who grew up in the Internet era have more opportunities to embrace genre films. Compared with their predecessors, they are more sensitive to the internet and are more keen on entertaining expression.

Of course, this influence is like a double-edged sword. The theme of crime has become the first choice in the creation of young directors.Xiaolian, who is in charge of film copyright sales on a video platform, told us that in the works of young directors they contacted in the past, crime films accounted for 80% of the genre films.

In Tao Taolin’s view, "the crime film has a strong genre model, and various elements such as suspense, action and murder are more convenient to implant, which makes it the first choice for young directors."

　

However, the Chinese genre films directed by young directors are still in a stage of reference and imitation. "Whether it is the image style, the film language and the narrative style, there are particularly obvious reference and reference traces, and it has not really formed its own style."

　

At the same time, the success of The Wandering Earth has emboldened many creators. The project planning of a head film company tells us that since the middle of last year, the number of projects with sci-fi themes or involving sci-fi elements has been much higher than in the past. Moreover, in the introduction of these projects, their benchmarking works are directed by Nolan.

　

In fact, genre films are likely to usher in more diversified development under the change of market wind direction. Although most of them are still in the primary stage of imitation and reference, as these directors polish their works one by one, they will gradually find their own style.

Ning Hao and Chen Sicheng are good examples. From the stage of learning and using for reference, they gradually realized the localization of genre and incorporated a lot of China folk culture into genre films.

　

Break the kidnapping of capital

Many people in the industry believe that although literary films are more easily recognized by film festivals, excellent genre films are actually more difficult. On the one hand, they need more investment support, on the other hand, they need more professional teams to intervene.

　

Weihao Cheng, director of "The Pursuit of Witnesses", admits that genre films will test the ability of young directors. He has said more than once that as a newcomer, the filming budget is limited, but the technical content of many scenes in genre films will be high, so it takes a lot of energy to prepare in the early stage, especially to test how we can show a stronger atmosphere with a small cost.

　

It is precisely because of these successful experiences in the past that Weihao Cheng has the opportunity to cooperate with Zhang zhen and Zhang Junning to shoot a new film "Seizing the Soul" with higher cost.

This kind of control actually lies in the director’s control over the budget, which can create infinite possibilities in the limited. Detective pu SonglingdirectorJia YanIn an interview with the media, I made a reply to the reasons for the failure of the work. He said, "These failures are all related to the budget. I can only tell you that the budget must be prepared before shooting, and it must be confirmed with the producer. "

It can be seen that the cooperative relationship between directors and producers also affects the quality of a work. When the new director is inexperienced, it will bring a lot of convenience to film creation if there are experienced producers involved. CarnivaldirectorVivian QuAlso said that the new director should not worry about lack of money, money can help improve production, but it is by no means a decisive factor.

At the same time, as a producer, she also gave her another level of thinking. "The director can be unconstrained, but the producer must predict the feasibility and can only allow a very small range of accidents. It cannot be said that the whole thing is an accident. The film should be presented in its best appearance, and at the same time, how to control the return in business should be considered. After all, the film is also a commodity. If the front is well controlled, there is no need to market it like that. "

　

It is true that it is an era of new directors, and various venture capital clubs and film companies have provided opportunities for new directors to show themselves through various support programs. However, under these opportunities, they can only create a truly universal film if they make a good story and integrate localized content into the film genre.

　　[car home Professional Evaluation] In the past two years, Honda and Toyota have been doing the same thing, that is, putting another car between their compact and medium-sized SUV models. The prices of these cars are cheaper than their big brother, but the workmanship configuration has surpassed that of the compact younger brother. Once these cars came out, they were basically well received and sold well. Toyota’s Lingfang is one of them. Today, I brought the test report of the flagship version of FAW Toyota-Lingfang HARRIER 2022 dual-engine 2.5L CVT four-wheel drive, which is the top model of the whole department with a guide price of 297,800 yuan.

●　Comfort evaluation

　　Lingfang’s seat is wide and thick, which is more comfortable to sit on. The inner padding of the seat cushion and backrest is soft and has no support or wrapping, but it is very comfortable to sit on. The front functional area is clear, and there is a physical air conditioning control area, so it is convenient to adjust the temperature and air volume.

　　The experiencer is 180cm, weighs 62kg, and the front seat is adjusted to the lowest position and the appropriate sitting posture. The front head space is left with one punch, and the front row remains unchanged and comes to the back row. The head space is left with four fingers, and the leg space is left with one punch and four fingers. The performance is not bad.

　　The storage space in the Lingfang car is quite satisfactory. The only small problem is that the size of the storage slot in the front row is a little small, and after putting the mobile phone, almost everything else can’t fit.

　　The size of the trunk of Lingfang is similar to that of Rongfang. After all, the wheelbase is almost the same. It is worth mentioning that the height of the trunk from the ground has reached 800mm, so it must be a bit laborious to carry large items.

　　Lingfang HARRIER 2022 dual-engine 2.5L CVT Four-wheel Drive Flagship Edition performs fairly well. As the top model of the whole system, all comfort configurations such as front/rear parking radar, panoramic image, reversing car side warning system, electric/inductive trunk, keyless entry, adaptive far and near lights, automatic air conditioning, front seat heating/ventilation, steering wheel heating, JBL stereo and so on are fully equipped.

　　Lingfang’s center console and door elbow are all wrapped in leather fabric, and the steering wheel and seat are all made of leather, which feels delicate. Overall, the materials used in the car are very good, which is much better than RAV4 Rongfang.

　　The configuration of the front seats is very high, the ventilation and heating are all complete, the comfort of the seats is also good, and the length of the seat cushion is in place for supporting the legs; However, the comfort of the rear seats is average, the sitting height is low, the length of the seat cushion is not enough, and the leg support is not good. Secondly, the configuration is not high, only the air conditioning outlet is provided, and there is no temperature and air volume adjustment system.

　　Lingfang’s noise test performance is remarkable. If it is not a strong power request, the driver and passenger can hardly hear the noise of the engine. During daily driving, the tire noise can still be heard obviously in the car. If the speed rises, the wind noise will be a little big, but the final measured data is ok, and the results at low and medium speeds are lower than the recommended values.

●　Dynamic evaluation

More exciting videos are all on the car home video platform.

　　In the acceleration test, the acceleration momentum of Lingfang was very strong at the moment when the brake was released. With good torque release and the blessing of the four-wheel drive system, there was no slippage in the initial stage, and the acceleration momentum in the middle and later stages remained very good. The 2.5L hybrid system did not disappoint, and the final acceleration score of 0-100km/h was 7.75 seconds.

　　The smoothness of the E-CVT gearbox is very good, and the vehicle power is very linear. In addition to the normal mode, Toyota also provides this car with ECO and SPORT modes. In the sports mode, the dynamic response of this car will be more intense, and the basic speed will be higher. Compared with the ordinary and ECO modes, we can still feel obvious differences. There is a small detail that I like very much. I like the feeling of the accelerator pedal very much. Its damping spring is very strong, so it won’t be very tired when driving in traffic jams. You can take advantage of the pedal.

　　Although Lingfang is a domestic SUV, the configuration of the power part of the top version is not low, and the hardware of motor+four-wheel drive is placed here, so its dynamic response speed and the force in the middle and rear sections are online, overtaking and merging within the legal speed limit is effortless, and the acceleration of 40-80km/h is better, which takes 3.78 seconds, and the performance of 80-120km/h is even more outstanding, which takes only 5.38 seconds.

　　Lingfang’s steering feel is heavy, and there are some empty positions in the middle, and the reaction and directivity of the front of the car are also somewhat blurred, but fortunately, the steering wheel will be slightly lighter at low speed, and parking will not be too laborious. On the whole, if the steering force is lighter, it may be more comfortable to drive every day.

　　Although Lingfang’s throttle responds quickly and accelerates smoothly, there will be no torque steering and suspension feeling when starting the car with full strength.

　　The suspension is still the calibration of the domestic SUV. The initial stage is relatively soft, and it filters well the fine bumps on the road surface, but its middle and rear stages are still relatively hard. In the past few days of testing, when I passed a relatively large ditch or speed bump, its suspension was not sloppy, and bang bang passed twice, which was very simple.

　　The overall texture of the chassis is very good, and the overall feeling is very strong. Its level is indeed higher than RAV4, and there is not much vibration introduced into the car. When passing through a large area or deep potholes, the car does not have abnormal sound or loose feeling, and the overall feeling is in line with the level that this price should have.

　　Like RAV4, the 2.5L hybrid version of Lingfang uses the E-Four four-wheel drive system. This set of electric four-wheel drive has a general ability to get rid of difficulties, and its horsepower and torque are also insufficient. First, the test of double front wheels and double rear wheels, Lingfang’s performance is not good enough, which is a little more laborious than many four-wheel drive models we tested, but it finally passed. Followed by the test of the cross axle, the vehicle did not hesitate too much, and the wheels did not slip obviously, and passed smoothly. It did not perform well in the test of single front wheel and single rear wheel. After a series of outputs, it could not get out of trouble, and the speed of limiting slip was a little slow and the strength was not enough, which failed the challenge.

　　The approach angle and departure angle of Lingfang are both 24 degrees, the bottom ground clearance is 19cm, the minimum ground clearance is 19cm, and the turning diameter is 11.75m m..

　　　The following is the test of cross-country field. First, it is a 36-degree slope. Compared with its eldest brother Lu Fang, Ling Fang’s performance in this project is good. Although the process is a little laborious, he finally succeeded in climbing to the top. The reason is that it is light in weight, and the pressure on the rear of the vehicle with a weight of 1760kg will be much less. However, the 42-degree slope is still the same. After the angle becomes larger, the lower rear wheel torque and grip are not enough for the vehicle to climb the slope, and the challenge fails.

　　The test performance of the roll slope is good, and there is no obvious sliding phenomenon at the front and rear of the car, and the direction can pass smoothly without too much correction. In the Butterfly Valley test, Lingfang performed well, and the vehicle did not support the bottom in the process of uphill. It was easier to do cross-axis movements at the top of the slope, and the challenge was successful.

　　In the continuous cannonball pit project, there was an obvious bottoming phenomenon in Lingfang, and it was ok when passing through the first steamed bun bag, but the vehicle was directly supported on the steamed bun bag at the second cannonball pit position, and the challenge failed.

　　Lingfang is not equipped with functions such as off-road mode and steep slope descent. Generally speaking, Lingfang’s four-wheel drive system and body size setting are more for highway four-wheel drive and bad roads. It will be more difficult to use it for some moderate off-road projects.

●　Safety evaluation

More exciting videos are all on the car home video platform.

　　Ling Fang’s performance in the brake test is not satisfactory. First, the vehicle’s posture is not good when fully braking, and the vehicle leans forward obviously. Second, the grip of the four tires is not very good, but the braking force is released evenly, the braking G value fluctuates unobvious, and the foot feel is also very good. This is reflected in this generation of Highlander, and the final braking distance of the vehicle at 100-0km/h is 40.62 meters.

　　Except for the steering damping, the overall handling of Lingfang is poor. When Zone A enters Zone B, the suspension support is very general, the car body has a large roll, the tire grip is not good, and the front of the car responds slowly when changing lanes urgently, so the driver needs to adapt for many times before finding the best turning opportunity. After entering Zone B, the intervention of electronic stability control system is not strong enough, which leads to the speed of Zone B entering Zone C is still too fast, and the braking process will be accompanied by the harsh sound of hub motor, and the highest passing speed is only 68.2 km/h.

More exciting videos are all on the car home video platform.

　　Lingfang has a moderate sitting posture in the front row, a good view, and a good view of the external rearview mirror. The internal rearview mirror is a streaming media rearview mirror, which has a good visual range and clarity, and it will be safer to drive at night.

　　The passive safety configuration of Lingfang is very comprehensive. The whole system comes standard with front airbags, front side airbags, front and rear head air curtains and knee airbags. It feels good to treat them equally.

●　Economic evaluation

　　The car we actually measured is the top model of Lingfang, with a guide price of 297,800 yuan. Generally speaking, it is still a little expensive, but at present, this car should have a discount of about 21,000-25,000 yuan, so the final landing price is ok. If you think it is still expensive, it is enough to buy a luxury version or a premium version, and the configuration can also meet the needs of home use.

　　　This fuel consumption test runs 104.5km, with an average speed of 31 km/h. Under this working condition, we test between congestion, urban roads and expressways, and start the ECO mode and engine start-stop function all the time. Because it is a summer test, the air conditioner is turned on all the time, and the actual filling of No.92 gasoline is 5.92L, and the measured fuel consumption is 5.7L/100km.

●　Intelligent evaluation

　　Similarly, the active safety configuration of Lingfang is also very complete. The whole system comes standard with a full-speed adaptive cruise system, including parallel line assistance, lane departure warning, lane keeping assistance system and lane keeping function. I like it.

　　Compared with the central control panels of most Toyota models I have tested before, Lingfang’s car system has indeed made great progress. First of all, the shape, including the thickness of the frame, is relatively thin. Second, its sensitivity and clarity are also online. In addition, the intelligence of the car machine is also very good. In addition to providing basic functions such as online navigation and online music, it also provides functions such as hotel reservation, online video, hotel reservation and take-away reservation.

●　Full text summary:

　　Lingfang’s performance in the performance test is not very good. Besides good acceleration performance, poor tire grip affects the performance of braking and elk test. If a set of tires with better performance can be replaced, the final test result will definitely be better. Off-road is also its weak part. The weak rear wheel power and general limited slip ability can’t help this car get out of trouble. But its advantage is actually not here. Urban roads are its home. It is actually very comfortable to drive every day. The power is very good, the noise of the engine is not very big, and the fuel consumption is still very low. Coupled with sufficient comfort and active and passive safety configuration, this car is definitely qualified as a home SUV.

　　Regarding the market of this car, I also visited several 4S shops and inquired about the current preferential price of Lingfang. Some of them gave the following policies: the fuel version discount is 15,000 yuan, the hybrid discount is 20,000 yuan, the installment car purchase rate is 0 for 2 years, the down payment is 60%, the installment car purchase discount is 23,000 yuan, the white car needs to be increased by 2,000 yuan, the vehicle is given a basic maintenance of 100,000 kilometers for 4 years, and the adhesive pad is all negotiable, but there is a 4S shop.

●　Comfort evaluation

　　The two main points are deducted. First, the information such as the average speed and subtotal time on the dashboard and the central control panel will be automatically erased after each restart of the vehicle, which is not conducive to the driver’s statistics of daily fuel consumption performance. I deducted points at the dashboard scoring point. Secondly, the tire noise is high at low speed, and the engine noise is high at high speed, and the subjective noise perception part is also deducted.

●　Dynamic evaluation

　　There are several main penalty points in this part. First, in terms of steering and driving stability, Lingfang’s steering feel is not accurate and heavy, and its controllability in the elk test and the performance of the vehicle when shifting its center of gravity are not very good. Secondly, the performance of cross-country venues is not good, except for the objective passing or not, the subjective experience is not very good, and points are deducted in these projects.

●　Safety evaluation

　　In this part, the performance of Lingfang is high and low, and the low part is that the performance of the brakes is really bad. Besides the actual performance, the subjective feeling is not good, but the car is very good in vision and the number of airbags, and the scores are all higher than the average score of the same level.

●　Economic evaluation

　　The total score of Lingfang in the economic evaluation part is 9.42, and the main reason for the high score is its fuel consumption performance. The measured fuel consumption per 100 kilometers is only 5.7L/100km.

●　Intelligent evaluation

　　The intelligent part got a score of 19.20, which was better than that of competitors of the same level, especially the active safety part, which was fully equipped and could fully meet the daily use requirements.

●　Total score of AH-100

In addition, Tanks expects to set up 30 overseas clubs this year, covering Southeast Asia, the Middle East, Australia, Russia and other regions.

It is a traditional folk custom in China to greet the New Year during the Spring Festival. It is a way for people to bid farewell to the old and welcome the new, and express their good wishes to each other. This traditional custom, which has lasted for thousands of years, is still an indispensable event on the first day of the Lunar New Year. It is called "New Year’s greetings" that "the elders and the young worship their relatives, and those who are close to each other congratulate each other". In ancient times, it was generally that the younger generation knelt down, kowtowed or bowed to their elders to pay New Year greetings, and then paid New Year greetings to their elders, relatives and neighbors in the village. On the way, when New Year greeting people meet, they all exchange greetings and say auspicious words such as "Congratulations on getting rich" and "All the best".

At the dawn of the first day of the first month, the whole family got up early, put on new clothes, and every household set off firecrackers, scrambling to "open the door". Then open the door and choose the direction of "Italy", and take a hundred steps to meet "XiShen", which is called "travel". After welcoming XiShen, the whole family gathered for dinner. After breakfast, I began to pay New Year greetings in the traditional way, but now I don’t have to kowtow and bow down.

Nowadays, the use of smart phones has gradually been given a new form of network New Year greetings by the Internet age, including various New Year greetings pictures, New Year greetings emoticons and New Year greetings to electronic red-envelope. Some expression packs are still animated after they are opened, with firecrackers and music sounds, just like a micro-movie. Before the Spring Festival in 2019, New Year’s greeting expression packs and New Year’s greeting languages appeared on the Internet, such as: Wangquan has returned to send money, and the golden pig is also coming; New year, new scenery, new atmosphere, new spring besides old cloth, and so on. Although these messages lack their own personality and thoughts, they are full of love and blessings, which is an important reason why netizens are willing to accept and forward them.

With the increasing material wealth and the continuous improvement of people’s income level, many people feel that the taste of the New Year is getting weaker and weaker. Because of the material abundance in daily life, the desire to have a "big meal" in childhood has become history. As long as your stomach can stand it, you can eat "New Year’s Eve" almost every day. Because of the development of internet, science and technology, media and performing arts, people can enjoy all kinds of cultural and entertainment feasts as they please 365 days a year, so there is no need to wait for the Spring Festival Gala only once a year. Because of the rapid development of communication and transportation, "one message from home is worth a ton of gold" has long been a thing of the past. Now, who can write a letter and go anywhere you want? It is easy for relatives to meet, and even if they don’t meet, they can chat by video.??

"After a busy year, the family has a big New Year’s Eve dinner together and keeps the old age together, enjoying the happiness of family and the beauty of life." At the Spring Festival group meeting in 2019, the General Secretary of the Supreme Leader talked about "New Year’s Eve" and "Keeping the Year" in a homely way, and further pointed out that "filial piety at home and loyalty to the country are the fine traditions of the Chinese nation".Paying New Year’s greetings is a traditional folk custom in China. Blessing the elders is the promotion of the filial piety culture of the Chinese nation; Thanks to relatives and friends, it is the admiration of knowing how to report German culture; Greetings to neighbors are the inheritance of Chinese civilization and etiquette culture … New Year greetings show simple but sincere emotional communication and exchange of ideas between people.

Although everyone feels that the taste of the year is getting weaker and weaker now, the Spring Festival still affects the hearts of hundreds of millions of Chinese; Although the telephone and the Internet have narrowed the distance between time and space, Spring Festival travel rush is still "unstoppable by human beings". Some people cross half of China just to have dinner with their families; Although new clothes can be taken off the hanger at any time, the brand-new look during the Chinese New Year still has a different meaning. This festival embodies family ties and nostalgia. No matter what way it is taken, its purpose and nature will never change. This is the beautiful yearning and prayer for the new year. The traditional flavor of the year is fading away, but what changes is its external form, and what remains unchanged is its internal essence. No matter globalization, informationization or modernization, we can’t lose the soul of traditional culture.

　　Guests who do not need to provide ID cards, face recognition or even register any information … … This kind of "three no-net appointments" can be described as frequent chaos.

　　The so-called "online room appointment" has the characteristics of online room selection, electronic payment, password unlocking, no need to meet, and high cost performance. A few days ago, the reporter of China Youth Daily and China Youth Network investigated in Guangzhou, Guangdong, Nantong, Jiangsu and other places, and found that with the rapid development of "online booking room" in the past two years, there are loopholes in the supervision of "online booking room", and it is impossible to implement the "four realities" system such as real name, real number, real time and facts. In addition, without effective supervision, "online appointment rooms" can easily breed illegal crimes. In addition to public security, problems such as fire control and sanitation have also become hidden dangers behind the rapid development of "online booking rooms".

　　Does "self-check-in" mean that registration is not required?

　　Open the life software such as Meituan, and the reporter of Zhongqingbao Zhongqingwang clicks to enter the "Hotel B&B" page. After checking the "B&B" option, a large number of houses come into view. What makes people feel strange is that, unlike the interface of hotel reservation, "online booking room" usually does not display information such as the name of the merchant in an obvious position.

　　"Exclusive whole house, 1 room, 1 bed, 2 people" and "2 rooms, 4 people" are the most eye-catching slogans of "online booking room" when it is sold online. In Panyu District, Guangzhou, the reporter randomly opened Meituan software, and searched the webpage information in a sales page called "Baby B&B". The reporter only knew that the B&B was located near Guangzhou South Railway Station. The specific address, house number and other information is vague. After paying 245 yuan, the software displays "Booking Successful".

　　Within a few minutes, the reporter received a text message on his mobile phone. "Online booking room" merchants inform the specific location, house number, electronic lock password and other information of the room through SMS. According to the information provided by the owner, the reporter went to Vanke Huibo Commercial Center near Guangzhou South Railway Station.

　　The reporter found that there was no sign clearly marked "B&B" or "online booking room" in the commercial center. The so-called "online booking room" is the apartment of the commercial center. Within a whole floor, more than 20 rooms are lined up in turn. The room number is marked on the light wooden door. Although it looks like a hotel, this "hotel" has no front desk.

　　After checking in, the reporter searched several times before finding the cleaning staff of the "hotel" in the corridor. After asking whether it is necessary to provide identity documents, Auntie stressed that her job is sanitation and cleaning, as long as she has successfully checked in.

　　The reporter found that the room not only provides washing machines and other equipment, but also has a pool and a console for customers to cook. This is also convenient for customers to stay here for a long time. Until the check-out, the store owner never showed up and the phone never got through.

　　In the check-in instructions of Meituan platform, the store has always emphasized self-service check-in and real-name registration, and reminded customers to "bring their ID cards to facilitate the check-in registration with the landlord". But in the actual operation, the check-in registration disappeared.

　　Unexpectedly, the reporter did not fill in my ID card information when booking on the online platform. Before and after the check-in, no staff member asked to register identity information. After checking out, I didn’t ask for supplementary registration identity information.

　　Coincidentally, in October this year, the reporter found a similar situation when investigating and interviewing in Nantong City, Jiangsu Province. This time, the reporter chose to order a "network appointment room" in Gaode map software. After paying 130 yuan, the reporter received a short message instantly. The message asked the reporter to make a phone call after arriving at the address provided by the message.

　　After arriving at the designated place, the reporter found that this floor is almost all "online booking rooms". A QR code with real name registration will be posted on the door of every room. When scanning the QR code, you need to fill in your real name and ID number, and after face recognition and authentication, you can swipe your registered ID card to check in.

　　There are still loopholes in the seemingly compliant "self-check-in" method. There is no front desk in the "online appointment room", and the boss is contacted by WeChat and telephone. The owner of the shop did not show up from beginning to end.

　　When scanning the QR code to fill in the information, "Add a roommate" is also one of the columns. However, after the reporter chose "no registration", he also successfully completed the registration and successfully checked in. This also means that no matter who customers bring or how many people they bring, there will be no relevant personnel to verify their identity and manage them on the spot.

　　Stick to the bottom line of protecting the safety of minors

　　According to public information, the prosecutor of Linping District Procuratorate in Hangzhou, Zhejiang Province recently handled a case about "online booking room". After 00, the boy Li Wei (pseudonym) dropped out of school at home after graduating from junior high school. Later, he was suspected of stealing a battery car and was criminally filed and released on bail pending trial.

　　What the prosecutor didn’t expect was that Li Wei disappeared during the bail pending trial. After investigation, the prosecutor found that Li Wei was actually smoking "e-cigarettes on his head" in the "online appointment room". Li Wei didn’t get a room. The "online booking room" was booked by a drug addict.

　　From July to October, 2021, this "online appointment room" became a fixed place for drug addicts to gather to smoke "electronic cigarettes" containing synthetic cannabinoids. Encouraged and seduced by others, Li Wei also began to smoke "e-cigarettes on his head".

　　In August this year, Nantong police found in their work that Zhu, the operator of a "online booking room" in Nantong city, did not register his real name when he received minors, nor did he comply with the "five musts" requirement for minors to stay. According to the provisions of the Law of People’s Republic of China (PRC) on Public Security Administration Punishment and the Law of People’s Republic of China (PRC) on the Protection of Minors, the public security organs punished Zhu for his illegal reception of minors.

　　In June, 2021, the Ministry of Public Security put forward the "five musts" requirements around the key links of hotel reception of minors, such as check-in registration, check-in inquiry and suspicious situation report: the identity of minors must be checked and registered truthfully; The contact information of parents or other guardians of minors must be asked and recorded for the record; Must ask about the identity relationship of the people living together and record it for the record; We must strengthen safety inspection and visitor management to prevent illegal infringement on minors; Suspicious cases must be reported to the public security organs immediately, and parents or other guardians of minors should be contacted in time, and corresponding safety protection measures should be taken at the same time.

　　In the rapid expansion of "online booking rooms", homestays and e-sports hotels, there are many security and fire hazards, which are likely to lead to conflicts and disputes. In this regard, Nantong Public Security Bureau took the lead in formulating "Guiding Opinions on Regulating Public Security Management of New Accommodation Types (Trial)" in Jiangsu Province last year, strengthening supervision through "three realities and five musts", keeping the safety bottom line firmly, promoting the healthy and orderly development of the industry, and safeguarding the legitimate rights and interests of accommodation personnel and operators.

　　In this summer’s special rectification, Nantong’s public security organs arranged a total of 7,485 online rooms and 44 e-sports hotels, conducted publicity and education for 12,562 employees through online reminders, offline interviews and signing letters of responsibility for public security and safety, handled 55 cases of irregular business, and arrested 121 suspects through investigation, which greatly purified the operating order of new accommodation formats and effectively ensured the safety of minors.

　　Chen Lei, deputy detachment leader of the Public Security Detachment of Nantong Public Security Bureau, said that at present, there are five kinds of situations in which minors stay in accommodation owners: First, minors are brought to the accommodation industry by the opposite sex in a state of drunkenness; Second, minors meet with heterosexual netizens privately and stay in the accommodation industry; Third, minors run away from home or don’t go to school on time, and go to the accommodation industry alone; Fourth, many minors stay in e-sports hotels or online booking rooms that can provide computer internet access environment and play games for a long time; Fifth, a number of minor men and women live together in the accommodation industry.

　　Nantong police reminded that operators, employees and parents of the accommodation industry should earnestly enhance the awareness of minors’ protection, find suspicious situations, report them to the public security organs in time, and jointly build a good social environment for caring for and protecting minors.

　　In order to make the "online booking room" a "sunshine room", the police in Changzhou City, Jiangsu Province have done a lot of work. In March of this year, Changzhou police took the lead in implementing the "Detailed Rules for the Administration of Public Security in Changzhou Online Rooms (Trial)" in Jiangsu Province, and incorporated online rooms into the management of special industries.

　　Especially for minors staying in "online booking rooms", Changzhou police require all stores to strictly implement the "five musts" system.

　　Bluetooth door opening, face recognition … … "Self-check-in" has also become safe and efficient. Li Jun, the captain of the Second Brigade of the Public Security Detachment of Changzhou Public Security Bureau, said that after several rounds of arranging, more than 2,000 "online appointment rooms" were identified in Changzhou. These operators should not only achieve "people’s identity", but also have safety facilities such as escape masks, smoke detectors and fire extinguishers.

　　Changzhou police adopt "red, yellow and green" color separation management according to the housing situation, and most rooms are given green signs representing "qualified". Under strict supervision, in April this year, Changzhou police dug up a "money laundering convoy" to help telecom network fraud gangs withdraw money from various places through in-depth research on the management module of "network appointment room", and arrested 17 suspects in one fell swoop. Among them, the police arrested six suspects only in the "online appointment room".

　　Let the "network appointment room" get rid of the "public security depression" as soon as possible.

　　Article 57 of the Law on the Protection of Minors clearly stipulates that when hotels, guesthouses, hotels and other accommodation operators receive minors, or receive minors and adults to live together, they should ask their parents or other guardians the contact information, the identity relationship of the residents and other relevant information; Anyone who is found to be suspected of violating the law and crime shall immediately report to the public security organ and contact the parents or other guardians of minors in time.

　　Jiang Ting, the procurator of the People’s Procuratorate of suyu district City, Suqian City, has been studying the related issues of "online booking room" for a long time. Jiang Ting said that in practice, some "online booking rooms" may not have been reported to the public security organs. While the emerging business forms are booming, there are loopholes and security risks in the unregistered "online appointment room".

　　Jiang Ting said frankly that even the "online appointment room" that has been reported has irregularities and illegal acts such as accommodating minors without the permission of guardians. The current punishment measures are still in accordance with the relevant provisions of Article 56 of the Law on Public Security Administration Punishment.

　　In reality, fines above 200 yuan and below 500 yuan are obviously not enough deterrent for these operators.

　　Jiang Ting said that in judicial practice, there is a blind spot in the supervision of "online appointment rooms". The threshold for "online booking room" merchants to settle in major platforms is very low. The major platforms hardly screen the information about the qualifications, business licenses and housing types of online booking operators. This makes the "network appointment room" have security risks such as the actual situation does not match the picture.

　　Jiang Ting suggested that the development of emerging formats is a concrete manifestation of the sound and upward development of the economy, which has injected a lot of vitality into high-quality development. Therefore, relevant departments should guide the orderly and healthy development of emerging formats. Relevant departments should also promote the legislative work on "online contract housing", improve the current shortcomings, and make online contract housing get rid of "public security depression" as soon as possible and become greener and more sunny.
