More than 30,000 people in Wenchuan were evacuated due to mountain torrents and mudslides.

On August 20, rescuers sent life jackets to the affected people in Xinzhuang Village, Keku Township, Wenchuan County. Xinhua news agency

Transfer tourists.

Transfer the affected people. According to China forest fire official micro

　　Sanjiang town mobile phone signal has been restored, and tourists are being evacuated.

　　Affected by mountain torrents and mudslides, sanjiang town, Wenchuan County was once interrupted by traffic and communication.

　　After five hours’ hard journey, at 7: 00 pm on the 20th, the reporter followed the rescue vehicle of Sichuan Fire and Rescue Corps and finally arrived in sanjiang town Town. At this time, the flood has receded, a thick layer of silt is piled up on the streets, and branches and other sundries are piled up on both sides of the roads, and the edges of many roads have been washed away.

　　It is understood that sanjiang town is organizing the evacuation of tourists in an orderly manner, but due to the interruption of national and provincial roads, the only way to transfer tourists abroad is to borrow the Yaozishan Village Road. With the rescue workers scrambling for communication, power supply and other infrastructure, the cell phone signal has gradually recovered.

　　Siniangshan town police relay escort to persuade stranded tourists to return

　　Xiaojin County, Aba Prefecture — Wenchuan County — The first-line road in Chengdu was interrupted, and the construction of Siguniang Mountain road could not pass normally, which led to tourists being stranded in Siguniang Mountain Town.

　　Upon hearing the news, Xiaojin police immediately arranged the Siguniang Mountain traffic police squadron to the Siguniang Mountain card point to persuade the stranded tourists to return, and at the same time communicated and coordinated with the construction party to release the stranded vehicles in advance. All police stations and traffic police squadrons along the highway set up two service persuasion points (Siguniang Mountain Card Point and Jiajin Mountains Qiaotou) to carry out persuasion, and Xiaojin traffic police squadrons escorted the stranded tourists from Siguniang Mountain Town in batches by relay — Meixing Town, Xiaojin County — Danba County, Ganzi Prefecture, safely escorted out of the country.

　　As of press time, the traffic police squadron of Siguniang Mountain persuaded more than 1,200 vehicles and more than 4,000 people to return. At present, except the tourists who are visiting Siguniang Mountain, all the other tourists have been persuaded to return.

　　Wenchuan police car clears the way and 100 buses are diverted to Beichuan.

　　In the early morning of August 20, heavy rains in Wenchuan County, Aba Prefecture, Sichuan Province caused many roads to be interrupted, so a large number of vehicles had to be diverted. They entered Beichuan from Maoxian County and borrowed Provincial Highway 302 to Mianyang, including hundreds of tourist buses.

　　Since Maoxian to Beichuan are all mountainous roads, Aba police and Mianyang police adopt a joint escort mechanism to implement traffic control on the roads and use police cars to clear the way to ensure the safe passage of all types of vehicles.

　　At the request of the Provincial Emergency Department, the Transportation Management Bureau of the Sichuan Provincial Department of Transportation arranged to mobilize the Chengdu Transportation General Vehicle to leave in batches and go to Wenchuan Shuimo to evacuate the stranded passengers. The first batch of 11 buses left around 5 pm, and the second batch of 9 buses also left at 17: 40.

According to Sichuan Online

　　Three policemen in Chengdu lost contact in disaster relief.

　　The two have confirmed their sacrifice.

　　Huaxi Dushi Bao (Reporter Zhong Xiaotong) In the early morning of August 21st, the reporter learned from the Dayi County Public Security Bureau in Chengdu that a deputy director and an auxiliary police officer of the Xiling Police Station of Dayi County Public Security Bureau died due to rescue, and another auxiliary police officer still lost contact.

　　At 2: 11 am on August 20, a flash flood broke out in Yunhua Village, Xiling Town, Sichuan Province, which caused some roads to collapse and was seriously damaged. Vehicles and personnel could not pass through and were in urgent need of rescue.

　　After receiving the police from Xiling Police Station, li ke (male, 34 years old), deputy director, led Zhou Zhengliang (male, 39 years old) and Luo Yonghong (male, 36 years old), the auxiliary police officers, to drive the police car for disposal.

　　At 3: 10 pm on the 20th, after the command center of Dayi County Public Security Bureau lost contact with li ke and others, it immediately ordered the surrounding police to search. At the same time, the follow-up forces were organized to rescue the help-seeking personnel, and the trapped personnel were successfully rescued.

　　At about 14 o’clock, searchers found the bodies of li ke and Zhou Zhengliang in Lianghekou and Huashuiwan Dam respectively. At about 20 o’clock, due to the weather, the search and rescue work for Luo Yonghong, a lost auxiliary police officer, was suspended, and the search and rescue will continue on the 21st.

Heavy! The tenth edition of COVID-19 diagnosis and treatment plan adjustment points.

　　Recently, the National Health and Wellness Commission and state administration of traditional chinese medicine organized the revision of the novel coronavirus Diagnosis and Treatment Plan (Trial Ninth Edition) and formed the novel coronavirus Infection Diagnosis and Treatment Plan (Trial Tenth Edition). The key revisions are as follows:

　　The name of the disease has been adjusted.

　　According to the "Overall Plan for Implementing" Class B and B Management "for novel coronavirus Infection by the Comprehensive Group of the State Council Joint Prevention and Control Mechanism, the name of the disease was changed from" novel coronavirus "Renamed "novel coronavirus Infection". With the continuous variation of Covid-19, the virulence of Omicron virus weakened after it became the main epidemic strain. The main symptoms of human infection were cough, fever, sore throat and so on, and only a few infected people would progress to pneumonia.

　　No longer judge "suspected cases"

　　With the increasing richness of diagnostic methods and the continuous improvement of diagnostic efficiency,At present, Covid-19 infection can be diagnosed promptly, quickly and accurately by nucleic acid and antigen detection.In most cases, there will be no cases where the epidemiological history and clinical manifestations are consistent with the characteristics of the disease, but the pathogen detection can not be clear for a long time.

　　Increase the positive test of Covid-19 antigen as diagnostic criteria.

　　Antigen detection has good detection sensitivity for infected people with high viral load.With the maturity of antigen detection technology and the improvement of detection accuracy, Covid-19 infected people, especially those with strong infectivity, can be diagnosed in time through antigen detection.Considering that most infected people are treated at home, the antigen detection operation is simple and convenient, which is convenient for infected people to carry out rapid self-detection.

　　Further optimize "clinical typing"

　　With the constant variation of the virus, especially since the epidemic of Omicron strain, the pathogenicity of the virus has been gradually weakened, and the characteristics of the disease have changed obviously. Most infected people have mild symptoms and the proportion of pneumonia has been greatly reduced.In order to better reflect the characteristics of the disease, the tenth edition of the plan adjusted the clinical classification, mainly according to the severity of the infected person’s illness, divided into "light, medium, heavy and critical", which is more in line with clinical practice.

　　Cases are no longer required to be "centralized and isolated"

　　With the implementation of Class B and B management measures, Covid-19 infected people can choose home treatment or medical institutions according to the needs of treatment, and all kinds of medical institutions can treat Covid-19 infected people.

　　Further improved the treatment method.

　　The anti-Covid-19 drugs that have been approved for marketing in China will be included in the new diagnosis and treatment plan to further enrich the antiviral treatment methods.

　　Further improve the diagnostic criteria and early warning indicators for severe and critical cases, and scientifically and accurately judge severe cases of infection in Covid-19. At the same time,The elderly who have not been vaccinated in the whole process will be added to the high-risk group of severe diseases, and the monitoring of vital signs, especially the monitoring index of finger oxygen saturation after rest and activity, will be added to the early warning index of severe diseases..

　　Further strengthening the concept of co-treatment of Covid-19’s infection and basic diseases, emphasizing the need to strengthen the monitoring of related indicators of infected people’s basic diseases and give corresponding treatment for basic diseases, which is more conducive to promoting patients’ comprehensive recovery.

　　Further optimize the clinical manifestations and treatment-related contents of children’s cases, put forward the characteristics of children infected with Omicron strain in combination with clinical practice, and improved the early warning indicators of severe cases in children.It provides a treatment plan for special situations such as acute laryngitis and nervous system complications that may occur in children infected.

　　Further improved the related content of Chinese medicine treatment.Strengthen the guidance of traditional Chinese medicine treatment for severe and critical cases, and increase the method of medication with symptoms, which is more suitable for clinical practice.On this basis, the Chinese medicine treatment plan for children’s cases is further improved, acupuncture treatment methods are added, and corresponding Chinese medicine treatment measures are provided in combination with the obvious cough of some patients in recovery period.

　　Adjust the "discharge standard"

　　The tenth version of the plan no longer requires the results of nucleic acid detection when the infected person leaves the hospital, but the clinician makes a comprehensive judgment based on the patient’s Covid-19 infection, diagnosis and treatment of basic diseases or other diseases, and health recovery.

　　When the patient’s condition is obviously improved, his vital signs are stable, his body temperature is normal for more than 24 hours, lung imaging shows that acute exudative lesions are obviously improved, and he can be converted to oral medication, and there are no complications that need further treatment, he can consider leaving the hospital.

　　Adjust the prevention and control of infection in medical institutions

　　After the adjustment of the epidemic prevention and control policy, all medical institutions have the possibility to accept cases of Covid-19 infection. The tenth edition of the diagnosis and treatment plan has adjusted the relevant contents of infection prevention and control in medical institutions.

　　Further implement the system of pre-examination and triage for outpatient and emergency departments and do a good job of patient diversion. At the same time, instruct patients and accompanying personnel to wear medical surgical masks or medical protective masks, and provide instructions on hand hygiene, respiratory hygiene and cough etiquette.

　　Strengthen the cleaning, disinfection and ventilation of consultation rooms, wards, offices and duty rooms.

　　Implement personal protection requirements of medical staff according to exposure risks.

　　Standardize the treatment of medical waste and implement terminal disinfection after patients are transferred out or discharged from hospital.

Some lesions in the annual physical examination can’t be found？ Expert： Physical examination needs a ＂sense of design＂

　　Medical Guidance/Professor Wang Fangjun from the First Affiliated Hospital of Guangzhou University of Chinese Medicine

　　No matter on the Internet or in real life, I can always hear people asking similar questions angrily and helplessly: one of my relatives and friends has a physical examination every year, and no problems have been found. Who knows that lung cancer has been found recently, or it is in the advanced stage! Therefore, people often ask bluntly: What is the use of physical examination? Why are some diseases still undetected? The reporter interviewed Professor Wang Fangjun from the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine.

　　Text, Figure/Guangzhou Daily All-Media Reporter Weng Shuxian Correspondent Fang Ning and Zhang Qiuxia

　　Don’t wait for the body to "hold on" before doing the examination.

　　"Physical examination is of course useful! The use is not small! " Wang Fangjun explained that the so-called physical examination is the abbreviation of "physical examination", which is a process in which doctors use their own senses, auxiliary examination instruments and experimental equipment to collect objective information on the health of patients or normal people and conduct health assessment.

　　In the past, many people went to the hospital after they felt obvious symptoms of the disease, or even "unbearable". As everyone knows, many diseases have no discomfort in the early or even the middle stage, especially cancer. When the symptoms are obvious, they often have developed to a serious stage, and the treatment effect is difficult to guarantee, even for life. Physical examination is a process in which people take the initiative to evaluate the health status of their bodies. Without waiting for the body to send out an obvious "unbearable" signal, they can find hidden dangers of diseases as early as possible and block the progress of diseases in time.

　　Why didn’t the physical examination find early lesions?

　　Why do you insist on physical examination every year, or are some early lesions not found in time? What do you think about this problem that puzzles many people?

　　"We should be clear about the fact that the health examination of normal people is not the same as the disease examination of patients who go to the hospital to see a doctor!" Wang Fangjun said that the examination of diseases is clear-cut, targeted, accurate and meticulous, and will make a relatively accurate diagnosis of diseases in a "positioning, quantitative, qualitative and regular" manner; The physical examination is only a screening process, and we don’t know whether the body is sick or not, which is equivalent to "casting a net". Therefore, we usually only choose some simple and cheap items that can reflect important organ functions.

　　If we sort out these "casting a net" health examination items, he thinks they can be roughly divided into three categories:

　　1. General examination: It belongs to the most basic examination items, and usually includes blood pressure measurement, heart and lung examination, electrocardiogram examination, palpation of liver, gallbladder, spleen and lymph nodes, etc., so as to roughly judge whether there are diseases of organs such as hypertension, heart disease, lung disease and liver and gallbladder.

　　2. Laboratory examination: generally including blood analysis (blood routine), urine routine, liver and kidney function, blood lipid analysis, tumor markers and thyroid function, to judge whether there are anemia, infection, hepatitis, nephritis, hyperlipidemia, tumor, leukemia and hyperthyroidism.

　　3. Imaging examination: it is essential in the current physical examination, which usually includes chest X-ray photos, B-ultrasound (liver, gallbladder, spleen, kidney, thyroid, etc.) and other items.

　　"Whether you apply for a medical examination on your own initiative or a medical examination organized by your work unit, you only choose a few inspection items to do." Wang Fangjun said that even "people who are not poor in money" have designed an expensive "luxury medical examination package" according to their own requirements, and in fact it is impossible to include all kinds of examination items in the hospital. Therefore, in theory, it is impossible for physical examination to "exhaust all items", and there will always be some early lesions that will be missed. Some people only check a few small items, and they are not necessarily targeted. Therefore, some early lesions have failed to be detected.

　　Tips: Optimize physical examination items to improve inspection efficiency.

　　So, how to improve the effect of physical examination more pertinently?

　　"In fact, the physical examination is also ‘ Technical work ’ , also need to have ‘ Sense of design ’ 。” Wang Fangjun analyzed that the above-mentioned physical examination items can be regarded as the preferred basic items, and it is recommended that all the subjects can be seriously examined. In addition, some targeted projects should be optimized according to the characteristics of age, gender and occupation, so as to improve the inspection efficiency. And how to choose the best, it is suggested that we can communicate with the doctor appropriately and design the best physical examination plan with the help of the doctor.

　　For example, he said that people over the age of 40 should appropriately increase items such as bladder, prostate, uterus and accessories when doing basic B-ultrasound (liver, gallbladder, spleen, kidney, thyroid, etc.) during physical examination; Women at risk of breast cancer should increase mammography and breast ultrasound; People at risk of heart disease can add items such as cardiac color Doppler ultrasound on the basis of ECG. If you are an older "smoker" or a patient with other high-risk factors of lung cancer, you should "upgrade" the chest X-ray photos to a low-dose CT examination of the chest to avoid missing the diagnosis of early lung cancer.

　　If some parts of the body are obviously uncomfortable, that is to say, some symptoms or signs have appeared, then the goal of the examination is more clear. Wang Fangjun reminded that the physical examination at this time may wish to refer to the contents of "disease examination" and ask the specialist to "tailor-made" the examination items, so as not to miss the early or even middle and late lesions.

Science popularization： five kinds of particles that ＂don’t exist＂ but can change the world

　　Particles refer to the smallest component of matter that can exist in a free state, including electrons and neutrons. The cornerstone of modern physics — — The physical standard model is essentially a "family tree" of a particle family, and its members are familiar to everyone. The Higgs boson, which finally revealed its beauty, was sought after by scientists from all walks of life as soon as it came out.

　　But there is an equally important class of particles that nobody cares about Of course, this is understandable, because these "quasi-particles" do not really exist, but their unique physical properties are enough to change modern science and technology. In a recent report, the British magazine New Scientist listed five quasi-particles that "don’t exist" but can change the face of the world.

　　Phonon: electric cowboy

　　In 2012, the Large Hadron Collider (LHC) at CERN discovered the Higgs boson, which is the mass source of other particles. So far, all 62 kinds of elementary particles have been discovered, and the standard model of particle physics has been perfected.

　　But without phonon, all this would not have happened.

　　The concept of phonon is developed in the process of studying lattice vibration. Li Baowen, director of the Center for Phononics and Thermal Energy Science of Tongji University, once explained that phonons are not real particles, but quasi-particles, which are quantized lattice vibrations. It is called a phonon because the essence of "sound" is the "vibration" of an object. In fact, the Greek word for phonon means sound.

　　The name phonon was first put forward by Igor Tamm, a physicist in the former Soviet Union, in 1932. He pointed out that just as light corresponds to electrons, sound waves can be associated with some particles we call "phonons". In solids, especially in semiconductors and insulators, "heat" is conducted through lattice vibration, that is, "phonons" are carriers of heat.

　　At room temperature, phonons are quasi-particles, and the heat conduction of solid materials is mainly realized by phonons. But at extremely low temperature, these quasi-particles "incarnate" into a group of "cowboys", driving away the "cattle" composed of electrons. These electrons act uniformly, and their resistance is almost zero, which is the principle of low temperature superconductivity.

　　It is the huge electromagnetic field created by superconducting magnets that makes protons bend in the large circular orbit of LHC. In the magnetic resonance imaging (MRI) scanner, these superconducting magnets "transform" as a command, guiding oxygen atoms in human tissues to "dance" and releasing traceable radio signals. In addition, phonons also play an important role in the field of thermoelectric materials. These thermoelectric materials can convert thermal energy into electrical energy, and it is also expected to realize scientists’ dream of reusing waste heat from automobile engines to supply power for electronic products.

　　Magneton: the king of spin

　　Since Tam put forward the concept of "phonon", scientists have gradually found many such quasi-particles in solids. Another such particle originates from spin, a quantum property that is the basis of magnetism. Spin is like an arrow on an atom, pointing south or north; When all spins in matter are aligned, a magnetic field appears. However, when this spin state is constantly reversed, a wave effect is created, which scientists call "magnon".

　　Ordinary computers and smart phones need electricity to store information, but the information of equipment power failure cannot be obtained. If a magnon is used, the information storage will depend entirely on the magnetic field without electricity, which is called Spintronics. The advantage of this method is that it consumes little power — — Excessive power consumption is one of the main problems encountered in miniaturization of transistor chips. If the magnetic oscillator is controlled by electromagnetic waves, the computer can completely get rid of the shackles of wires and electricity.

　　Exciton: the secret weapon of plants

　　The earth gets more energy from the sun in an hour than all mankind consumes in a year. Plants play the role of energy catchers, and excitons are the "secret weapons" for plants to perform this task.

　　In any substance, electrons exist in different energy levels. When a photon strikes the surface of an object, it will excite electrons to a higher energy level, leaving a hole. Electrons are negatively charged and holes are positively charged. Under certain conditions, the Coulomb attraction between them will bind them together in space, so the complex formed is called excitons.

　　The leaves of plants contain light-trapping proteins, and the electrons in the light-trapping proteins will be excited to absorb photons and leave their positions, leaving a hole, electrons — Excitons formed by hole pairs will float around the photosynthesis production line of plants.

　　When excitons arrive at specific positions where they are needed, electrons recombine with holes and release energy, which plants use to decompose water into hydrogen and oxygen.

　　This photosynthesis is the root of life on earth, and human beings have been looking forward to simulating this reaction in solar cells. In 2013, researchers at the Massachusetts Institute of Technology found a way to "photograph" excitons directly, which took a key step towards the ultimate goal.

　　According to the online edition of Science magazine in 2009, Leonid Butov, a physics professor at the University of California, San Diego, and his colleagues have made several transistors based on excitons. These transistors are expected to become the basic modules of new computers, and the circuits assembled by them will become the first computing device using excitons in the world.

　　Mayorana Fermion: Quantum Hero

　　If you want to have a real multi-process computer, you can turn to a quantum computer for help. The quantum computer, which is still in its infancy, makes use of subtle and uncertain quantum states and can give multiple solutions to the same problem at the same time. As long as the external environment does not disturb the "magic" of the quantum computer, it can run stably.

　　Majorana quasiparticles can provide "qubits" for quantum operations, which makes quantum computers more powerful.

　　The information in an ordinary computer is stored in "bits", and each bit is coded as 0 or 1; Information bits in a quantum computer can exist as 0 and 1 at the same time, but this superposition state is very fragile. For this reason, physicists have been looking for ways to make qubits more stable.

　　In 1930s, Italian theoretical physicist ettore majorana predicted that there must be a particle, which is the same as its antiparticle. The concept of "majorana particle" was born. It has no mass and no charge. It is its own antiparticle and always appears in pairs. Because of its special properties, majorana particles are electrically neutral and rarely interact with the environment, so it becomes an ideal carrier for quantum information coding.

　　Since majorana particles always appear in pairs, which means that there are two copies of the information they contain, theoretically speaking, majorana qubits are more tolerant to external noise. However, according to Attila Geresdi of QuTech Institute in the Netherlands, these qubits exist in the background of huge electronic effects, and it is very tricky to extract the information of majorana quasiparticles.

　　In June this year, the research team of Jia Jinfeng of Shanghai Jiaotong University wrote in the Physical Review Express that they had successfully captured the Mayorana fermion in the laboratory through a special artificial film composed of topological insulator materials and superconductor materials, which not only contributed to the development of quantum computers, but also helped to further uncover the mystery of dark matter.

　　Wilfermion: Double-faced Jiaowa

　　"Weyl fermions" are like shy "cousins" of electrons. In 1929, the German scientist H. Weyl proposed that there is a kind of electron with no "mass" and can be divided into two different "chirality" of left-handed and right-handed, and this electron is called "Wilfermion".

　　The fermion has two key characteristics: massless and chiral. The lack of mass means that it can move at high speed, and at the same time, it is extremely resistant to interference that is inconsistent with its chirality, which makes it difficult to scatter: two different types of fermion streams can be close together without interaction. It has been suggested that these properties can make it the basis of computers beyond spintronics computing power.

　　However, for more than 80 years, scientists have not observed the fermion in the experiment, and the semi-metallic materials with the characteristics of fermion have only recently appeared. On July 16, last year, Science magazine published the experimental results of the team of physicist Zaid Hassan of Princeton University. The team announced that they found "Waier Fermion" in "Waier Semimetal"; On July 20th, official website, Institute of Physics, Chinese Academy of Sciences, announced that the research team led by Fang Zhong, a researcher from the Institute, had successfully discovered the Verfermion in TaAs crystal for the first time. Therefore, the era of "Weyl Weyltronics" has appeared on the horizon, but there is still a long way to go.

Press conference of the State Council Office： Natural resources help build a well-off society in an all-round way

　　Cctv news(News broadcast): The State Council Office held a press conference today (October 29th), and the relevant person in charge of the Ministry of Natural Resources introduced the positive contribution made by the field of natural resources to building a well-off society in an all-round way.

　　According to the Ministry of Natural Resources, cultivated land is the lifeblood of grain production. According to the results of the third national land survey, we have kept the red line of 1.8 billion mu of cultivated land protection set by the state and completed the task of 1.865 billion mu of cultivated land in 2020 set by the state plan.

　　At the same time, China’s geological survey has also made great progress. During the "Thirteenth Five-Year Plan" period, eight 100 million-ton oil fields, five 100 billion cubic meters of natural gas fields, five 100 billion cubic meters of shale gas fields and 311 large and medium-sized mineral fields were newly discovered. The Ministry of Natural Resources also said that in the past 10 years, China has made great achievements in ecological protection and construction, with a total net increase of 260 million mu in woodland, grassland, wetland, river surface and lakes with strong ecological functions. China has also issued institutional documents such as coastal wetland protection, grassland protection and restoration, and wetland protection and restoration, initially forming a new pattern of ecological restoration.

Meteorological heat index sends out small ＂shade＂

Release date: July 29, 2010 at 10:56

Intern reporter of China Meteorological News Sun Nan Anjia

　　Hot! With the arrival of the dog days, the high temperature in the whole country has come back again. On July 26th, the Beijing Meteorological Observatory issued the yellow warning signal of high temperature again. The citizens in Beijing complained: "The highest temperature in the weather forecast is only 35℃, but it feels like it is almost catching up with the high temperature of 40℃ a few weeks ago!"

　　Why is there always a gap between the temperature people feel and the temperature predicted by the meteorological department? Is the data monitored in the louver box discounted to the temperature?

Record the history of air temperature

The standard temperature is measured in the louver.

　　Taking the pulse for the sky is a scientific and rigorous work. Li Xiaoquan, the chief expert of China Weather Network and former director of the Central Meteorological Observatory, told us that there are strict standards for the setting of louver boxes, which are set according to the regulations of the World Meteorological Organization and the norms of meteorological observation.

　　The thermometer should be erected at a height of 1.5 meters from the ground and installed in a louver box with ventilation on six sides. It should not only ensure that it can communicate with the outside air, but also ensure that it will not be excessively affected by the wind, and at the same time avoid direct sunlight. In addition, the environment around the louver box also has strict requirements. It is internationally unified that the observation field must be empty and flat, and there should be no trees and tall buildings around it, and it should be placed on the lawn with a thickness of no more than 20 cm.

　　Only in this way can we ensure that the global meteorological observation data are representative, accurate and comparative, facilitate the global sharing of temperature data, correctly analyze the changes of weather systems and provide reliable weather forecasting services.
Every day, at a fixed time, observers should observe the temperature of the louver. Stations that switch to automatic meteorological observation will also regularly transmit observation data to forecasters for weather analysis and forecast.

　　Li Xiaoquan said that the temperature forecast mentioned in the weather forecast refers to the forecast of air temperature. The air temperature is very local, which is related to altitude and surrounding environment. Human activities are generally at the height of 1 meter to 2 meters. Therefore, the air temperature in the 1.5-meter-high louver box can reflect the real atmospheric situation of the human activity layer, which represents the undisturbed standard air temperature in the natural state.

Different feelings under the same sky

The difference of somatosensory temperature caused by many influences

　　The somatosensory temperature refers to the temperature that people feel. Due to the differences of regions, environments and individuals, there is a gap between the somatosensory temperature and the actual temperature.

　　There are many factors that affect the somatosensory temperature. Li Xiaoquan thinks that the most important factors that make people feel the temperature difference are relative humidity and wind power.

　　When the temperature is high and the humidity is high, the sweat on the skin surface cannot evaporate well, so the heat dissipation efficiency of the human body is low, and the somatosensory temperature is higher than the actual temperature. So even in the hot weather of 35℃, as long as the humidity is low, you will feel dry and not too uncomfortable. However, in most cities in the south and in the rainy season in the north, the relative humidity will reach more than 80%. At this time, as long as the temperature exceeds 32℃, the human body will feel sultry and unbearable.

　　Wind, like a huge fan, virtually accelerates the flow of air, and can quickly take away sweat from human skin, making people feel as if the temperature has dropped. In addition, the influence of solar radiation is also very obvious. Under the same temperature, humidity and wind speed, the temperature difference between sunlight and the somatosensory temperature in the shade can be 4℃ to 6℃.

　　The somatosensory temperature also varies from person to person: people in different regions feel different. Indian tourists who are used to the high temperature of 45℃ will not feel very hot when they come to China to see the Expo, but tourists from cold northern Europe are hard to adapt. Even in the same area, the feelings of the elderly and children will be very different. Even two adults in the same area will feel different when standing in the sun. Physical condition, clothes color, skin color and even good or bad mood can affect people’s feeling of temperature. As the saying goes, "being calm and naturally cool" is a good portrayal of the influence of people’s emotions on somatosensory temperature.

　　In the new round of high temperature, the public clearly felt the difference between the somatosensory temperature and the real temperature, and some people started the experiment of frying eggs with manhole covers. Crack, crack, crack, crack, crack, crack, crack, crack, crack, crack, crack. Under the direct sunlight, the asphalt road was baked with oil. Some people took out a thermometer to measure the ground temperature, which actually reached 70℃ to 90℃. Many netizens suspected that not predicting the road temperature was for fear of unnecessary panic caused by excessive temperature.

　　In this regard, Li Xiaoquan explained that the temperature should be representative, and the temperature of different underlying surfaces is different. It is a universal standard method to observe the ground temperature by burying the thermometer half in the soil. The meteorological department has a record of monitoring the surface temperature, but predicting the ground temperature in summer has little practical significance for citizens’ travel activities. Regardless of the ground temperature, people should choose to walk with shoes.

Thermal index forecast for weather "cooling down"

Humanized service reminds people of sun protection and heatstroke prevention

　　Meteorology affects all kinds of human activities everywhere. As people pay more and more attention to meteorology, the task before meteorologists is not only to talk to the sky, but also to talk to people.

　　Li Xiaoquan believes that meteorological departments in various regions should provide the forecast of somatosensory temperature index according to local people’s living habits, topography and landforms, not necessarily as accurate as the live temperature, but at least should distinguish grades. "I think the weather forecast in the future will tell people whether the weather tomorrow will be dry, comfortable and hot, sultry or very sultry, not just the dry’ maximum temperature of 35℃’."

　　At this year’s World Expo, the heat index forecast of the Expo site, which has been prepared for nearly a year, was launched on Shanghai Weather Online in many languages. Thermal index forecast of Expo site: Shanghai model 34, German model 39, Hong Kong model 33 … Shanghai Meteorological Bureau introduced internationally famous thermal index forecast models. This thermal index forecast product is released regularly twice a day.

　　Geng Fuhai, head of the Urban Environment Center of Shanghai Meteorological Bureau, said that the thermal index is an index describing human comfort. Use the thermal index calculation models of various countries to calculate the possible somatosensory temperatures of people in various countries. For example, the actual temperature is 33℃, the Shanghai model shows a thermal index of 34, the American model shows a thermal index of 120, and Americans know that it is 120 degrees Fahrenheit at a glance.

　　Ms Guan, a tourist visiting the Expo from Anhui, said: "The introduction of the heat index is very humanized. Although the weather has been sultry for several days, I feel very happy when I go online to see the meteorological service in the Expo Park before going out every morning."

　　"Although the thermal index has been launched, the relevant verification issues are still being discussed internationally. The somatosensory temperature is influenced by personal factors, and everyone has differences, so the operation of this model is difficult to be accurately verified. " Yan Fuhai said.

　　Tang Xu, director of the Shanghai Meteorological Bureau, also said that the meteorological forecast service is not only the Expo meteorological service, but also provides the internationally accepted standard temperature forecast, and also provides various refined products according to the needs of various units in the city and the feelings of pedestrians on the road. Tang Xu said: "our work should keep pace with the times and meet the needs of the broad masses of the people. This is the direction of our efforts. Meteorological standards should be adhered to, but follow-up services should also be strengthened. "　　　

　　Weather can also make life better. "People-oriented" is not only the ruling idea, but also the proper meaning of the meteorological department’s continuous improvement of public service level. Just as Li Xiaoquan said, under the premise of doing a good job of live temperature forecast, the forecast of somatosensory temperature index can make meteorological services icing on the cake.

It takes internal strength to stabilize this bowl of mala Tang.

Tianshui is on fire! Accompanied by the red pepper running from the nose to the brain, the string of "bouquets" in hand and the boiling soup pot bottom, Tianshui attracted thousands of netizens in front of the screen to fly and take the high-speed train to come here and experience the "YOLO" for themselves.

A bowl of mala Tang makes a city with fire. The sudden explosion of fire, netizens have shouted Tianshui Wenlv: "You have to catch this wealth!" This time, the Tianshui municipal government also focused on "listening to persuasion", and started the "pet powder mode" with the actions of the whole city: painting the walls overnight, opening the Mala Tang bus line, picking up foreign tourists free of charge at airports and stations, and holding a special meeting on Mala Tang service guarantee, so as to do a good job in health protection without dead ends … The effective experience accumulated by the predecessor "online celebrity City", Tianshui people took out all the "Tao Xin Wo Zi", just to keep this hard-won. According to the data, as of March 14th, the popularity of tourism search in Tianshui increased by 186% in the past week. According to the data from Meituan and the public, from March 16th to March 17th, the advance booking volume of Tianshui’s tourism consumption (including hotels and lodging, classic tickets, transportation, etc.) increased by about 18 times year-on-year. Since the "out of the circle" of Tianshui Mala Tang, the overall order volume of Tianshui Wenlv Market has increased by 40% year-on-year.

From the smell of "Zi" last year to the feeling of "Bin" at the beginning of this year, and today’s "Mala Tang" in Tianshui, the siphon effect triggered by the cultural tourism market has made all cities deeply feel the powerful empowerment role provided by the cultural tourism industry for urban development. However, looking at these "fire out of the circle" cities, we can turn "flow" into "reserve", which is ultimately inseparable from hard work and accumulation.

As the saying goes, one side of the soil and water raises one side. The local grass, trees, bricks and tiles are condensed with rich historical background and unique customs, which can not be replaced by anyone or anything. Just as the local products Longnan pepper and Gangu pepper, which make Tianshui explode, have made this bowl of mala Tang the essence. What attracts tourists to Tianshui is not only this bowl of mala Tang, but also the lonely smoke in the desert, Maijishan Grottoes and Fuxi Nuwa’s "Poetry and Distance".

In this sense, if you want to win the initiative in regional development, you need to tap regional characteristics according to local conditions, expand service projects according to the situation, and strive to create your own "highlight moment." We should actively build a catalytic holographic service system. Through a series of explosive cultural tourism projects, we will create high-quality and cost-effective services, trigger the deepening and extension of urban awareness and recognition, and realize the promotion and optimization of multi-format services such as talents, business and investment. We should actively cultivate local characteristic brands and expand brand influence. Carefully build "time-honored brands", launch unique public brands of local products, build a modern commercial core area with "both prosperity and fireworks", and stimulate potential consumption. It is necessary to keep up with market changes, closely follow the needs of tourists, further optimize the tourism environment, scientifically formulate marketing strategies, boldly innovate marketing methods, make products more "aligned", make demand more "in place" and let "small resources" trigger "big effects".

Optimizing financial resources to support scientific and technological innovation

　　Developing new quality productivity is the inherent requirement and important focus of promoting high quality development. The reporter learned from the Ministry of Finance that in 2024, the financial sector will focus on strengthening the dominant position of enterprise innovation, giving play to the role of demand traction, improving the resilience and safety level of the industrial chain supply chain, stimulating the vitality of scientific research personnel, and at the same time focus on deepening the reform of the allocation and use mechanism of financial science and technology funds and vigorously developing new quality productivity.

　　"To implement the innovation-driven development strategy and achieve high-level scientific and technological self-reliance, it is necessary to improve the new national system, optimize the allocation of innovative resources, strengthen the national strategic scientific and technological strength, and promote the deep integration of innovation chain, industrial chain, capital chain and talent chain. In recent years, the state finance has given priority to science and technology as a key area of fiscal expenditure. " Wang Dongwei, Vice Minister of Finance, said.

　　Statistics show that from 2018 to 2023, the financial expenditure on science and technology increased from 832.7 billion yuan to 1,056.7 billion yuan. At the same time, we will comprehensively use policy tools such as tax incentives, government procurement, asset management, and finance to vigorously support scientific and technological innovation. In 2023, the state’s preferential tax policies to encourage enterprises to increase R&D investment continued to be "overweight", and the policy implementation was more accurate, effectively enhancing the confidence and confidence of enterprises in R&D investment and injecting more momentum into the innovation and development of enterprises. Judging from the prepayment declaration of enterprise income tax in 2023, enterprises have accumulated 1.85 trillion yuan of R&D expenses plus deduction, up 13.6% year-on-year, of which manufacturing enterprises enjoy 1.1 trillion yuan of extra deduction, accounting for nearly 60%. With the support of a series of central policies and the strong guarantee of financial resources, a large number of innovative achievements have emerged one after another.

　　Li Xuhong, vice president and professor of Beijing National Accounting Institute, believes that the accelerated gathering of innovation kinetic energy in China has benefited from the continuous improvement of a series of preferential tax policies to support scientific and technological innovation, and implemented a series of preferential policies for innovative subjects such as high-tech enterprises, small and medium-sized scientific and technological enterprises, and R&D institutions. While encouraging enterprises to increase investment in R&D, they have fully guided innovative resources to gather in enterprises, which has provided strong support for the high-quality development of the real economy and contributed tax power to promoting industrial upgrading and transformation and cultivating new kinetic energy. On the other hand, the increase in financial investment in science and technology provides financial support for the implementation of the innovation-driven development strategy, strongly supports the development of new industries and emerging formats, and promotes industrial upgrading and innovation-driven.

　　"To promote the development of new quality productive forces, financial strength is indispensable. Under the complicated overall economic situation, the financial sector has maintained its support for investment in scientific and technological innovation, supporting the development of new quality productive forces from multiple levels and angles. A series of innovative breakthroughs in key scientific and technological fields and major application fields cannot be separated from the continuous support of financial funds. " He Daixin, director of national academy of economic strategy Finance Research Office, said.

　　Wang Dongwei said that in 2024, the financial sector will take more effective measures to promote the construction of a modern industrial system with scientific and technological innovation and vigorously develop new quality productivity.

　　On the one hand, in terms of policy orientation, we should pay attention to four aspects. First, focus on strengthening the dominant position of enterprise innovation. We will implement the structural tax reduction and fee reduction policy and focus on supporting scientific and technological innovation and manufacturing development. Give full play to the inciting role of financial funds, promote financial resources and social capital to invest more in scientific and technological innovation, and promote the gathering of various innovative resources to enterprises. The second is to pay attention to the role of demand traction. Make good use of the advantages of domestic super-large-scale market, make greater efforts to promote the application iteration of innovation achievements, implement and improve the insurance compensation policy for the first (set) of major technical equipment and new materials, and solve the initial application bottleneck in a market-oriented way. The third is to pay attention to improving the resilience and safety level of the industrial chain supply chain. Integrate and optimize relevant financial projects, focus on key industrial chains, and support research to break through a number of short-board and weak technologies. We will implement the financial support policy of "specialization and innovation" for small and medium-sized enterprises, and drive more enterprises to focus on market segmentation and take the road of "specialization and innovation". Fourth, pay attention to stimulating the vitality of researchers, support the pilot reform of salary system in universities and research institutes, accelerate the pilot reform of ownership or long-term use right of post scientific and technological achievements, and fully mobilize the enthusiasm and creativity of researchers.

　　On the other hand, in the use of funds, efforts should be made to deepen the reform of the allocation and use mechanism of financial science and technology funds and achieve the "top four". The first is a strong foundation. Increase investment in basic research, applied basic research and cutting-edge research, and support the promotion of original innovation ability. The second is to tackle key problems. Vigorously support the fight to win key core technologies, support the layout of a number of major national science and technology projects, and accelerate the seizure of the commanding heights of science and technology. The third is strong power. Focus on national laboratories, national scientific research institutions, high-level research universities and leading enterprises in science and technology, and support the strengthening of national strategic scientific and technological strength. The fourth is strong efficiency. Strengthen the overall planning of projects, funds, talents and innovative resources of the base, comprehensively strengthen performance management, and strive to improve the use effect of science and technology funds.

　　"Developing new quality productivity and promoting high-quality development is a long-term process. The financial department is broadening the scope of support and strengthening support, and giving full support to researchers, key laboratories and related enterprises for a wider range of basic research and key technology research in a larger field that is in urgent need of financial support at this stage. " He Daixin said.

Old brands, new faces, which domestic new year goods are popular？

　　Customers are shopping for tonics at Yuanding Farm Store, Changying Tianjie, Beijing. Our reporter Kang Pu photo

　　Recently, Linyi City, Shandong Province opened its doors to welcome guests, and more than 300 old brands and honest businesses settled in, attracting many citizens to buy new year’s goods. Xinhua News Agency reporter Li Ziheng photo

　　As the Spring Festival approaches, people choose Spring Festival couplets, blessings, lanterns and other new year goods to greet the Spring Festival with great prosperity. The picture shows the citizens of Nanjing, Jiangsu Province, shopping for Spring Festival ornaments in a trade city on January 13th. Photo by Su Yang (People’s Vision)

　　Beijing Chaoyang District Changying Tianjie Shopping Center is crowded with people, and Yonghui Supermarket is full of people. All kinds of lanterns and Chinese knots with rich, safe and blessed characters are scattered from the ceiling, creating a festive and peaceful atmosphere.

　　The year is approaching, and the flavor of the year is getting stronger. When it comes to buying new year’s goods, eating, drinking, wearing and daily use are indispensable, and every household is busy for this.

　　Fairs, trade fairs, supermarkets, and e-commerce platforms have started the New Year Festival early, and the dazzling array of goods makes people eye-catching.

　　What do consumers have in their shopping carts? What has changed compared with previous years? Which domestic brands are favored for the new year? Reporters go in and out of supermarkets and fairs, visit e-commerce, and show you this year’s new year’s market.

　　New marketing, old brands continue to be strong.

　　"Hurry to prepare for the weekend, you can’t do it at once, supermarkets, shopping malls, and markets have to go to many places." In Yonghui Supermarket, Changtian Street, Chaoyang District, Beijing, Ms. Wang stuffed several cheap square roast duck gift boxes into an already full shopping cart. "Some time-honored brands are bought every year, and the Chinese New Year is just a familiar taste! Daoxiang Village cakes are bought for the elderly, and roast ducks bring a few boxes to relatives and friends. Everyone loves to eat old brands and has a bottom in their hearts. "

　　"From the multi-point statistics, in Beijing, Quanjude, Niulanshan and Sanyuan are the representatives of ‘ Jingwei ’ New year gift boxes sell well; In Zhejiang, consumers prefer Shaoxing Huadiao wine, and 53-degree flying Maotai is also on the list. " Liu Guihai, a partner of multipoint Dmall, said.

　　The shelves of old products are often surrounded by customers, while some unfamiliar faces are often ignored.

　　"It’s the same in our store. The new brand this year is not as good as the old brand." Zhao Pu, general manager of Super Species Beijing, told reporters frankly. "The new brand, you see and went away, very few people are willing to try, or choose the old brand more at ease. The same is true for fruits and vegetables. For example, the 17.5 orange of Nongfu Spring has been deeply loved by consumers in recent years, and the fruits of Happy Orchard have also sold well. "

　　Turn your eyes to the southwest of China. Chengdu Century City Convention and Exhibition Center in Sichuan is crowded with people, and the Spring Festival shopping festival is in full swing, just like Sichuan red oil hot pot. On January 11th, the first Saturday after the launch, the sun was shining brightly, and more than 80,000 people poured into the Convention and Exhibition Center, making people overwhelmed with all kinds of exhibition halls.

　　Pengzhou Jiuchi salted duck, Zigong cold rabbit, Jianmen native chicken, Jinhua ham, Dalian seafood, etc. The local products and old brands in Sichuan and all over the country are mouth watering, and the stable quality formed over the years has taken root in consumers’ hearts.

　　Old brands keep up with the new marketing trend, which is also an important factor for the continued strength of products.

　　"Ready, all the girls! Coming, the Great Wall is red! There are still 8,000 sets, 6,000 sets, and 1,000 sets left. Let’s go to the next one … …” In 12 seconds, a 6-bottle Great Wall Cabernet Dry Red was snapped up by fans in the live broadcast room in Li Jiaqi.

　　With the continuous reduction of tariffs in China, domestic red wine is facing more intense competition. During the New Year Festival, Great Wall Wine achieved good sales results with the help of e-commerce live broadcast and online celebrity delivery.

　　Precision marketing also contributed. Multi-point Dmall integrates online and offline through personalization and digitization, helping Wuhan Zhongbai Supermarket to increase the sales of Great Wall dry red wine by 1.4 times year-on-year.

　　In the south where there is no heating, air conditioning has become a necessity for many families in winter. How can we win consumers in the fierce competition of the New Year Festival?

　　The answer to the beautiful air conditioner is to use popular elements to match the folk culture of the year to arouse consumers’ good memories about the folk customs and tastes of the year.

　　While launching the online activity of "Making a list for the hometown customs", Midea also launched several animated short films. In the animation "Song of the twelfth lunar month", "Twenty-three, candied melons stick … … Twenty-seven, buy beauty! … … Watch the Spring Festival Evening on the 30 th night, and the beautiful air conditioner will celebrate the New Year! " The cheerful soundtrack and the adapted lyrics make people laugh, and the marketing slogan of "Beautiful New Year Festival, Warm China Year" is kept in mind.

　　Abandoning the single promotion discount and starting from the emotional needs of consumers, it is not only a new year’s promotion, but also a new attempt to build a brand by using interesting and heart-warming marketing methods to evoke people’s common memories of the new year’s customs.

　　New elements, young people lead the trend.

　　During the reunion of relatives and friends in the New Year, drinking is indispensable. Besides white wine, red wine, yellow wine and beer, what other choices are there?

　　A "post-90 s" girl is tasting several colorful fruit wines in the super species store in Changying Tianjie. "The liquor is too strong, and the taste is very strong. After drinking it, the head is stunned, the fruit wine is lower, and the taste is richer. This booth has different choices such as lychee, green plum and peach, which is very suitable for girls to drink at parties."

　　"Fanzui Flower Pavilion has not been promoted in Beijing for a long time, and the consumer market has not been fully opened, but it is more popular in the southern market." Salesman introduction.

　　Generally speaking, fruit wine is still a new face in China. Xiao Liu and his wife, born after 1990s in Shijiazhuang, Hebei Province, created a fruit wine brand called "Buqiang", which specializes in hawthorn wine and plum wine. The output is not high, but they have accumulated a stable customer base. After several months of brewing, it will be listed in time for the coming of the Spring Festival.

　　"The wine is seriously homogenized, and we want to bring some different flavors to young people who are pursuing new ideas." Xiao Liu told reporters.

　　In addition to the online shopping festival created by e-commerce platforms such as "double 11" and "June 18th", the Spring Festival is another peak time for people to buy electronic products. Under the guidance of young people, electronic products have become an important category of new year’s goods. Especially in the past two years, mobile phone brands in China have risen collectively. In 2019, the construction progress of 5G signal base stations has been accelerated, and 5G mobile phones have become the new favorite on many young people’s shopping lists.

　　In the recently hit TV series Joy of Life, Tian Yu, an actor who plays the role of Wang Qinian and whose popularity has soared, came to the offline store of Jingdong Home to live broadcast the goods as the "Star Store Manager". Many domestic brands such as OPPO, Glory and Xiaomi were popular among consumers.

　　With the continuous enrichment of goods in 2008, the traditional new year’s goods have also been played with new tricks. Spring Festival couplets are a necessary new year’s goods for every household, but they always lack new ideas, such as "people are diligent in three spring mornings, the land is fertile and the grain is abundant", "good every year, step by step" and "post-90 s" and "post-00 s", which are unconventional, and write their unique expectations for life into the Spring Festival couplets: "Get rid of poverty without losing your hair, wear gold without wearing clothes", "Become beautiful and handsome, off the charts, and have money and leisure for promotion and salary increase". … Students, white-collar workers and programmers’ whimsy of "opening their brains wide" brings new ideas to the taste of the year, and a special customized Spring Festival couplets business is also emerging.

　　Wang Wenjie, born in 1990s, opened an online shop in Taobao to write Spring Festival couplets. He can imitate a variety of fonts, including the round body that girls like and the running script that boys like. "Now is the peak season for writing Spring Festival couplets. Tmall New Year Festival has 100 orders every day, and at most it can write more than 300 pairs." Wang Wenjie said.

　　Statistics show that in the 15 days before January 7th, 2.53 million people have searched for the keyword "Spring Festival couplets", and the sales volume of Spring Festival couplets has doubled compared with last year. The surge in sales volume of Spring Festival couplets is inseparable from young people’s demand for personalized Spring Festival couplets and customized Spring Festival couplets.

　　New explosions, "send health" continues to heat up.

　　Going home for the New Year, visiting the elderly and visiting relatives and friends can’t be empty-handed. Some people want to look good in packaging, but more and more people take health as their first choice.

　　"If you give it to the elderly with insufficient qi and blood, I suggest you pair it with Radix Astragali and Radix Angelicae Sinensis. Young white-collar workers like you, who always stay up late and have poor sleep, should have some ginseng, dogwood, Schisandra and Ziziphus jujuba seeds. They can be paired with Poria, tangerine peel, yam and radix Pseudostellariae because they are sedentary and have heavy body moisture."

　　In the store of Yuanding Farm in Tianjie, Changying, the salesman introduced several collocations to customers fluently, which aroused the interest of reporters.

　　"Can I see your formula?"

　　"There is no paper, it’s all here." The salesman pointed his finger at his head.

　　"I have been here a few times and feel that the effect is not bad. Because work is too tired, exercise is less, I don’t avoid eating, and my lifestyle is not very healthy, so I often come here with a few prescriptions to soak in water to adjust my body. " Ms. Cheng, a white-collar worker who works nearby, told reporters, "It’s almost the New Year, so I’ll buy some for the elderly at home."

　　Yuanding Farm, which originated in Shanghai, brings high-quality Chinese herbal medicines from Changbai Mountain to fast-paced modern cities and provides healthy choices for people to buy new year’s goods.

　　Many high-end nourishing health products have also been included in the new year shopping list. According to the data of JD.COM Big Data Research Institute, the turnover of bird’s nest, donkey-hide gelatin and ganoderma lucidum spore powder increased by 263%, 122% and 71% respectively this year. Time-honored domestic products have become the explosion of new year’s goods, and the turnover of Dong ‘e Ejiao 250g has increased nearly 15 times in the same period.

　　Tea is also a healthy and error-prone gift.

　　The reporter turned over the sales record of a tea shop in Longtian Street Shopping Center. Black tea such as Zhengshan Xiaozhong and Jin Junmei and oolong tea such as Dahongpao and Anxi Tieguanyin became the most popular varieties these days, while the sales of green tea such as Biluochun and Longjing were much less.

　　"Black tea warms the body and nourishes the stomach, which is suitable for drinking in winter. During the Chinese New Year, people eat a lot of big fish and meat, and there is overnutrition. Oolong has a good effect of removing oil and getting tired. " The salesperson explained.

　　Paying attention to healthy consumption is a common tendency of consumers of all ages.

　　"3, 2, 1, the link! … … No, can I add it? " In the live broadcast room of Li Jiaqi’s New Year Festival, which mainly focuses on "post-90s" and "post-00s", nearly 6,000 yuan massage chairs were sold out in a few seconds. Statistics from JD.COM show that the sales of massagers and massage chairs increased by nearly 200% year-on-year. Middle-aged people prefer cervical vertebra instruments, and the number of buyers increases the fastest, reaching 72% and 61% respectively.

　　In addition to health care, what should I do if I have a headache, brain fever, cold and fever during the Chinese New Year? I don’t want to go out, and the hospital is overcrowded. "The child told me that I can consult an expert with Ali Health App and buy medicine online and deliver it directly to my home." Ms. Zheng, a Beijing citizen, said.

　　Ali Health launched Internet medical care, minor illness consultation, chronic disease follow-up, prescription online circulation, medical insurance online payment, drug delivery to the home, and the whole process of online medical treatment and drug purchase experience, which can be called "one time without running".

　　Parents’ well-being is a child’s greatest wish. Going home during the Spring Festival, buying a "parents’ physical examination card", accompanying the elderly to do a comprehensive physical examination, and checking physical hazards have become an important way for the younger generation to show filial piety. In addition, anti-aging, oral health, hair planting, Ali Health also launched a variety of tangible goods and services to meet the demands of different groups, so that health and beauty can accompany the New Year.

　　The most beautiful thing in the world is reunion. The consumption trend is changing, and the taste of the year will be constantly innovative. However, the Chinese New Year carries people’s hopes and expectations for a better life, and Chinese’s deep-seated cultural genes and common memories have not changed. Only by seizing this opportunity can domestic brands occupy a favorable position in the Spring Festival consumer market.
