Recently, with the further implementation of the new ten epidemic prevention regulations, how to prevent and control Covid-19 has attracted much attention, and some rumors are also waiting for opportunities. Rumors such as "canned yellow peach can relieve COVID-19’s symptoms", "multiple drugs can be eaten together quickly" and "negative antigen test means no infection" spread rapidly on social networks.

　　To this end, the Hangzhou rumor platform focuses on the topics that have attracted much attention during the epidemic, such as masks, vaccines, drugs, symptoms, antigen detection, oxygen/hydrogen generators, health codes, disinfection, diet (folk prescription for COVID-19), and key groups (elderly people, pregnant women, children, patients with cardiovascular diseases, and patients with liver diseases), etc., and sorts out various rumors in a classified manner, and attaches relevant expert suggestions and scientific answers to improve the quality of life. At the same time, we sorted out the recent public inquiries about the fever clinic in Hangzhou, the nucleic acid results were not available, the mixed tube was positive, and the yellow code was changed. We tried our best to help the public in Hangzhou effectively solve the problem of medical treatment.

First, masks

　　1. Wearing a mask for a long time can lead to pulmonary nodules?

　　Lung nodules are mostly benign, and the causes are varied, including air pollution, bacterial infection, vascular diseases, inflammatory diseases, etc., which have nothing to do with masks! Under the normal use of qualified medical surgical masks, the ethylene oxide gas in the masks will not be sold until it is analyzed and qualified, which will not cause lung harm.

　　2. Can the mask be reused?

　　The cumulative wearing time of each mask shall not exceed 8 hours, and the continuous use shall not exceed 4 hours. If it is dirty, deformed or damaged, it shall be replaced in time. Masks used in public places are not recommended to be reused. Keep your hands clean when wearing a mask. Wash your hands or disinfect your hands before removing the mask, and don’t touch the outer layer of the mask. Wash your hands or disinfect your hands after removing the mask.

　　3. The thicker the mask, the better?

　　Although the medical mask is thin to the touch, it has a high filtering effect. The three layers of water barrier, filter layer and moisture absorption layer effectively prevent the virus from invading and ensure the comfort of wearing. Although the cotton masks on the market are thick, they do not have the function of preventing infectious diseases.

　　4. Can I wear multiple masks to prevent the virus?

　　Just use one mask. When the protective materials are insufficient, the medical staff will use KN95+ surgical mask and wear it in a special way to ensure the protection of the nose and mouth.

　　Mask identification guide:

　　Disposable medical masks and surgical masks belong to Class II medical devices and are subject to product registration management. The product registration number and production standard will be marked on the outer packaging of masks produced by regular production enterprises. Only five codes can meet the epidemic prevention requirements: medical protective mask (GB19083-2010), medical surgical mask (YY0469-2011), disposable medical mask (YY/T 0969-2013), daily protective mask (GB/T 32610-2016) and children’s mask (GB/T 336).

　　Log on to the website "china food and drug administration-Data Inquiry", click "Medical Devices", select "Domestic Devices", and enter the registration number marked on the mask package to inquire.

Second, the vaccine

　　1. Is it useless to get a vaccine?

　　Xia Gang, Director of the Department of Health and Immunity of the National CDC: Vaccination still has a good effect in preventing serious illness and death. For the elderly over 80 years old, if one dose of vaccine is not vaccinated, the risk of death will be 14.7%, and if three doses of vaccine are vaccinated, the risk of death will be reduced to 1.5%. Compared with no vaccination, the risk of death will be reduced by 9.3 times after three doses of vaccine.

　　2, vaccination is not as good as infection once?

　　Vaccination can prevent infection, disease, serious illness and death. At present, the effect of Covid-19 vaccine in preventing severe illness and death is still very remarkable. A large number of monitoring and research have shown that the risk of severe illness and death is very high compared with the vaccinated people, especially among the elderly and people with chronic basic diseases.

　　3. Is it too late for vaccination at present?

　　Wang Huaqing, chief expert of immunization program of China CDC, said that it really takes some time to produce protective effect after vaccination. Generally, it takes one to two weeks to produce antibodies after vaccination, but if a relatively high level of antibodies is to be produced, it will take about four weeks after full immunization. He said that the time to produce antibodies after strengthening immunization is faster and shorter, and the level of antibodies produced is also higher.

　　4. Can I claim compensation for COVID-19 vaccine?

　　Recently, a net post said that "COVID-19 vaccine can be compensated on the national civil administration website", with a link to the website and a notice of payment, so as to induce people to pay attention to forwarding. In fact, the so-called "national civil affairs website" in the net post does not exist at all. Through the official website of the Ministry of Civil Affairs, the relevant information of "receiving vaccine compensation" does not exist. The news on the Internet is purely a rumor.

Third, diet

　　1. Can drinking high alcohol cure COVID-19?

　　Li Lanjuan, an academician of China Academy of Engineering, said that alcohol with a medical concentration of 75% can be used to disinfect medical devices, but drinking alcohol cannot prevent and treat COVID-19. Long-term drinking will lead to the decline of immune function, but increase the risk of infection.

　　2, eating oranges as antigens will turn yang?

　　Antigen detection is not a sample collection of the oral cavity and throat, so it has nothing to do with the substances in the oral cavity. Generally, daily diet will not affect the antigen detection results.

　　3. Can canned yellow peaches relieve COVID-19’s symptoms?

　　Canned yellow peaches are rich in nutrition. For many people who have poor appetite due to colds and fever, a proper amount of yellow peaches can also help to replenish energy and boost appetite. But it cannot relieve the symptoms of the disease. Especially when coughing, do not eat it, which may aggravate the symptoms.

　　4. Garlic, ginger and pepper can prevent Covid-19 infection?　

　　The World Health Organization made it clear in official website that there is no evidence that ginger, garlic and pepper can prevent COVID-19 virus; Although these foods have certain antibacterial and anti-inflammatory properties.

　　5, salt water gargle can prevent Covid-19 infection?

　　As early as January 22nd, 2020, Zhong Nanshan team publicly denied that "gargling with salt water can prevent COVID-19". At that time, Zhong Nanshan’s team made it clear that gargling with salt water is good for cleaning the mouth and throat, and helpful for pharyngitis. However, the part invaded by novel coronavirus is in the respiratory tract, and gargling can’t clean the respiratory tract. Moreover, there is no research result suggesting that salt water can kill novel coronavirus.

　　6. Electrolyte water is also out of stock? Does it really work?

　　The product introduction of electrolyte water shows that this product is an ordinary electrolyte beverage, which has no medicinal value or health care function. It is recommended to drink no more than 3 bottles per day. Kai Zhong, director of Kexin Food and Health Information Exchange Center, said that in some cases, electrolyte water is really needed, but it is not necessary and irreplaceable. He pointed out that when there are symptoms such as fever, if you can eat normally, you don’t need to supplement electrolytes. If you don’t eat all day and sweat or have severe diarrhea and vomiting, you need to pay attention to supplementing electrolytes. He suggested that eating fruit, drinking porridge, medical rehydration salts or electrolyte drinks are all ways to supplement the electrolyte lost by the human body.

　　7. Do you need to hoard vitamin C effervescent tablets?

　　Vitamin C, also known as ascorbic acid, can cause adverse reactions in urinary system, digestive system or blood system if taken in excess. Experts suggest that healthy people recommend food supplements, and it is not recommended or necessary to drink effervescent tablets every day.

Fourth, drugs

　　1. Take a variety of medicines together, increase the dosage, and recover quickly?

　　Cui Hongsheng, Director of Respiratory Department of the Third Affiliated Hospital of Beijing University of Chinese Medicine: Just choose one kind of western medicine antipyretic, such as ibuprofen or acetaminophen. We should grasp the principle of "stop the disease in the middle" and try not to use it together. Pay attention not to exceed the daily dose, otherwise it will damage the liver.

　　2. Is the online transmission of "COVID-19’s medication sequence chart" reliable?

　　When taking drugs, we should consider the symptoms of patients and the climate at that time. There are taboos when taking drugs, and we should not blindly take drugs. Pay attention to the adverse reactions and shelf life of drugs when using drugs. Patients with chronic diseases can consult a doctor in advance to avoid blindly "hoarding medicine".

　　Who reminds COVID-19 to avoid using ibuprofen?

　　The news first came from a study published in the sub-issue of The Lancet in March 2020. At that time, the World Health Organization quickly clarified that the proposal was not against the use of ibuprofen. With the passage of time, more and more evidences show that ibuprofen can be used for COVID-19 infection.

　　4. Can taking medicine prevent colds/flu or COVID-19?

　　Antipyrets, cold medicines, cough medicines and phlegm-resolving medicines are all common family medicines, but these medicines can only relieve symptoms instead of preventing diseases. You should not take medicine when there are no symptoms. Although many drugs are over-the-counter drugs (OTC), improper use will cause side effects and damage to liver and kidney functions. Be sure to read the instructions carefully before taking the medicine.

　　5. Take antibiotics after infection?

　　Antibiotics such as cephalosporin and Archie have corresponding indications of infectious diseases caused by various pathogenic bacteria. Antibiotics have no antiviral effect on virus infection, whether in Covid-19 or other viruses. In fact, the role of antibiotics is to relieve the related symptoms in the process of anti-bacterial and anti-inflammatory when treating all kinds of sensitive bacterial infections, rather than directly relieving these uncomfortable symptoms by antibiotics.

　　Therefore, whether positive infection is found, or symptoms such as sore throat and cough appear after infection, antibiotics are generally not needed, and antibiotics are only necessary when viral infection leads to complications of bacterial infection.

　　6. Can Chinese medicine and western medicine be eaten together?

　　Academician Zhang Boli: If you are infected, western medicine antipyretics and traditional Chinese medicine cold medicines should not be taken together as far as possible. For example, Chinese patent medicines with antipyretic effects such as Lianhua Qingwen, Jinhua Qinggan and Xuanfei Baidu Granules will not be taken together. Other traditional Chinese medicine and western medicine should be taken at intervals of 1 hour to avoid mutual influence. Of course, if you take cold Chinese medicine, but the sore throat is obvious, you can take Liushen Pill, Qingyan Dropping Pill and other symptomatic drugs. At the same time, we should grasp the principle of "stopping the disease in the middle" and stop taking the medicine in time after the symptoms disappear.

　　Try to take only one kind of Chinese medicine for cold, and it is not necessary to take two or three kinds together. Most of these medicines contain bitter and cold medicines for clearing away heat and toxic materials, which are easy to hurt the spleen and stomach and are not conducive to recovery. The same is true for western medicine antipyretics, so you can choose one, avoid combined medication, and pay attention to not exceeding the daily dosage, otherwise it may cause damage to the liver.

　　7. How do families prepare medicines scientifically? Do I have to buy all the medicines in the First Edition of the Catalogue of Drugs for Infected Persons in Covid-19?

　　Zhao Qingwei, director of the Clinical Pharmacy Department of the First Affiliated Hospital of Zhejiang University School of Medicine, said that the publication of this catalogue does not mean that so many drugs need to be prepared. Most families only need to prepare one or two drugs for the symptoms that may occur after COVID-19’s infection. In view of the possible symptoms such as fever and cough after infection, it is suggested that the family can prepare an antipyretic analgesic and a cough medicine, and the amount should be 3 to 7 days. For children, children over 6 months can choose ibuprofen or acetaminophen, one of which is enough; Children from 2 months to 6 months are advised to choose acetaminophen; It is not recommended to take two antipyretics alternately or at the same time, so as not to increase the burden on children’s liver and kidney and cause adverse reactions. The dosage should be adjusted according to the child’s age and weight. It is not recommended for infants to take drugs blindly within 2 months. It is recommended to cool down physically and seek medical advice in time when the symptoms are serious.

　　8. Is it necessary to buy "COVID-19 Oral Medicine" with a price of 2980 yuan?

　　Paxlovid is an oral small molecule COVID-19 therapeutic drug, which is used to treat adult patients with mild to moderate novel coronavirus (Covid-19) with high risk factors for progression to severe diseases, such as the elderly, chronic kidney diseases, diabetes, cardiovascular diseases, chronic lung diseases and other severe high risk factors, and is taken under the guidance of a doctor. In response to the hot sale of therapeutic drugs in COVID-19, Yu Chengbo, chief physician of the Department of Infectious Diseases of the First Affiliated Hospital of Zhejiang University School of Medicine, said: "It is not excluded that the market is blindly obedient." Yu Chengbo said that according to research, more than 95% of COVID-19 infected people are asymptomatic, and such people do not need medication; A small number of them are mild symptoms, so it is enough to take drugs for symptomatic treatment.

　　At the same time, the drug also has contraindications, drug interactions and adverse reactions. It is recommended to take it under the guidance of a doctor and not to use it at will.

Five, antigen detection

　　1, antigen self-test box "a box is hard to find"? Do you want to hoard it?

　　Feng Zhanchun, a professor at the School of Medicine and Health Management of Huazhong University of Science and Technology, said that antigen testing is generally used in acute infection, that is, sample testing within 7 days of symptoms of suspected people. If you find flu-like symptoms, such as fever, dry cough, muscle aches, etc., you can conduct self-testing and screening. Antigen positive, that is, "two bars", is mostly detected after two days of fever. Therefore, the antigen should be tested two days after flu-like symptoms such as fever and cough, and then again after the symptoms basically disappear.

　　2. What is the accuracy of antigen detection? Is it different from nucleic acid testing? Does negative antigen test mean no infection?

　　As an effective means of rapid screening, antigen detection may produce some false positive or false negative results. Because the principle of antigen detection is to indicate the existence of virus through the combination of virus protein antigen and specific antibody, scientifically speaking, there will be a certain probability of cross-reaction, which will lead to false positive.

　　In addition, the sensitivity of antigen detection is slightly lower than that of nucleic acid detection. When the virus concentration is still very low in the early stage of infection, the existence of virus may not be accurately detected by antigen detection kit, which will lead to false negative. The probability of this false negative depends on the sensitivity of the antigen reagent used, which may be around 1%-5% under normal circumstances.

　　3. The darker the color of antigen detection lines, the more virus content in the body?

　　Antigen detection is a qualitative judgment of virus protein antigen, that is, to judge whether there is a virus or not, but not directly to judge whether the virus load is more or less. Therefore, the color depth of the lines on the antigen detection board can not accurately explain the concentration of the virus.

Six, oxygen generator/hydrogen generator

　　Can a family prepare an oxygen/hydrogen generator to cope with infection?

　　Only severe and critical patients need oxygen. But in this scene, the oxygen generator at home can’t play a therapeutic role. Moreover, too high concentration or too long time of oxygen inhalation will lead to oxygen poisoning, so oxygen inhalation treatment should be carried out under the guidance of medical staff or professionals.

　　The hydrogen generator is also unnecessary. In the latest ninth edition of the diagnosis and treatment plan, this treatment method no longer exists. Because the role of hydrogen in the treatment of lung diseases is mainly to improve the utilization rate of oxygen and drugs, it does not mean that hydrogen itself can treat lung diseases.

　　At the same time, compressed hydrogen, compressed oxygen, etc. are commonly used dangerous chemicals, which may cause danger if the storage conditions are not suitable (such as high temperature or damaged containers).

Seven, symptoms

　　1. Can you tell COVID-19 by coughing?

　　Recently, a small program called "Intelligent Voice Recognition" can automatically recognize "normal" or "suspected COVID-19" results after recording. Experts said that the effectiveness of this method needs further verification, and at the same time, we should be alert to the abuse of related technologies. Nucleic acid detection is the "gold standard" of diagnosis, and faster and more convenient antigen detection can be used as a supplementary means.

　　2, COVID-19 infection will have serious sequelae?

　　Academician Zhong Nanshan said that there is a strict definition of sequela in medicine, which means that the damage caused by the disease exists for life. Some COVID-19’s symptoms will gradually disappear, so we don’t call them sequelae. I haven’t seen any particularly obvious cases of long-term dysfunction of organs. COVID-19 patients are generally not contagious after rehabilitation.

　　3, a fever is infected with Covid-19?

　　Zhong Nanshan, an academician of China Academy of Engineering, said that the recent fever was caused not only by COVID-19 infection, but also by the flu, and a few people may have double infection. At this time, it is also in the high incidence of influenza in winter. Therefore, patients with fever should be isolated at home according to their own situation, or go to the hospital for further examination.

　　Zhong Nanshan also suggested that patients with fever should generally pay attention to the first day and the second day. If the fever has not gone down in a day or two, they can do COVID-19 antigen test at home. If it is negative, they can wait. If COVID-19’s antigen is positive and you don’t feel anything else, you don’t need to go to the hospital first, just stay at home.

　　4. Are Covid-19-positive people asymptomatic if they just cough and have a fever?

　　If the positive infected person only has a cough and fever, and there is no lung infection, it can be classified as a mild case, but it is not asymptomatic. From the current national case data, asymptomatic and mild cases after Omicron infection account for more than 90%.

　　According to the current definition, an asymptomatic infected person refers to a person who is positive for Covid-19’s pathogen test and has no related clinical manifestations, such as fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea and other symptoms and signs that can be self-perceived or clinically recognized, and whose CT imaging has no COVID-19 imaging characteristics.

　　Mild patients may show symptoms of upper respiratory tract infection such as moderate and low fever, dry throat, sore throat, stuffy nose and runny nose, as well as symptoms such as fatigue and olfactory dysfunction, but there is no pneumonia.

　　5. "Good morning to Erwin Engst"? Will "Yang" be "Yang" again after once? How long is it possible to have a secondary infection?

　　After being infected with Covid-19 once, the immunity formed by human body will play a certain protective role. However, Omicron may rapidly mutate into new sub-branches and have strong immune escape ability, and the recovered people cannot completely avoid secondary infection. Once infected, you can’t be immune for life!

　　However, foreign statistics show that the probability of secondary infection within three to six months is quite low after being infected with Omicron, regardless of symptoms, and most people will not be infected with Omicron again for a long time.

　　For individuals, the best way during the epidemic period is to implement protective measures, including wearing masks, paying attention to hand hygiene, keeping social distance, and actively vaccinating Covid-19 vaccine to reduce the risk of infection.

　　6. Will repeated infection make the symptoms worse?

　　At present, there is no conclusion that repeated infection will lead to more serious clinical results. Judging from the current cases, even if individual patients have a tendency to aggravate their symptoms when they are repeatedly infected, this ratio is very low. The pathogenicity of Omicron virus is weakening. No matter whether it is the first infection or reinfection, the probability of serious illness is very low.

Eight, health code/nucleic acid proof

　　The health code is going to be invalid? Can’t find the personal vaccination certificate?

　　As of 12: 00 on December 13th, no province or city in China has issued a notice on the invalidation of health codes. Vaccination records will not be deleted.

Nine, disinfection

　　1, ultraviolet light 0.3 seconds to eliminate Covid-19?

　　Ultraviolet ray has a good sterilization effect, but its penetration is poor. The effective area of air disinfection is 1.5 -2 meters around the lamp tube, and the surface of the object should not be more than 1 meter away from the polluted surface when disinfecting, so it needs to be used within the applicable range to ensure the disinfection effect. The surface of the ultraviolet lamp tube must be kept clean, and the irradiation time depends on the intensity of the lamp tube and the pathogenic microorganisms killed. Generally, the irradiation time of the traditional ultraviolet lamp on the market is not less than 30 minutes. High-intensity, low-ozone ultraviolet germicidal lamp can be irradiated for 30 s to 60 s, but it is expensive, and the general medical high-intensity ultraviolet lamp needs several hundred thousand yuan.

　　2. The higher the concentration of disinfectant, the better?

　　Excessive concentration of disinfectants, especially chlorine-containing disinfectants, will cause discomfort to people’s mouth, respiratory tract and lungs, and may even cause damage to organs and tissues. At the same time, it will also cause corrosion, rust and discoloration of disinfected objects. When using disinfectant, it should be used according to the product instructions, including the scope of use (such as air, table, tableware or food, etc.), concentration and dosage. Do not adjust these parameters yourself.

X. Key population

　　1. Pregnant women are more likely to be infected with Covid-19?　

　　Qiao Jie, Dean of Peking University Third Hospital, pointed out that the Omicron infection rate of pregnant women is close to that of the general population. The types of symptoms are similar to those of the general population, such as dry throat, cough, runny nose, aches all over, fever and so on. Generally speaking, compared with the general population, infection has not brought more impact on the health of pregnant women.

　　Pregnant women with basic diseases such as hypertension and diabetes should strengthen self-protection. Women with pregnancy plans had better get Covid-19 vaccine before pregnancy to enhance their immunity. Try to adjust your physical condition before you get pregnant.

　　2. What should the elderly do if they are infected with COVID-19?

　　Wang Meihua, chief physician of respiratory medicine of Xixi Hospital in Hangzhou, said that those who are asymptomatic or have mild symptoms without serious underlying diseases, and those whose underlying diseases are in a stable stage, and those who need hospitalization, such as serious organ dysfunction such as heartless lungs, kidneys and brains, can be treated at home. During the period, patients should take temperature measurement and self-health monitoring once every morning and evening. Asymptomatic people do not need oral medication. Zhao Qingwei, director of the Clinical Pharmacy Department of the First Affiliated Hospital of Zhejiang University School of Medicine, said that after taking the medicine, the body temperature remained higher than 38.5℃ for more than 3 days, and the old people whose original basic diseases were obviously aggravated and uncontrollable should be referred for medical treatment in time. It should be noted that elderly people who usually take aspirin should avoid using antipyretics containing ibuprofen; Patients with hypertension should pay attention to monitoring their blood pressure when taking cold medicine containing ephedrine.

　　3. How can children judge whether they are infected with COVID-19? How to use medicine?

　　The simplest judgment principle is to look at the child’s mental state. If children have a good mental reaction, they should eat, drink and play, and generally do not need to worry.

　　If the following conditions occur, you should seek medical attention in time: the child has a fever for more than 3 days, and his mental state is poor after fever. He always wants to sleep, even if his body temperature drops, his spirit is not good; Children are always fidgety and crying, unable to appease; Frequent coughing affects daily life and sleep; Frequent vomiting, loss of appetite, and even rejection of milk by small babies; Breathing increases rapidly, even breathing is difficult, and infants groan and gasp; Decreased urine volume, increased stool frequency or purulent bloody stool; Fever accompanied by a new rash; Describe the pain in the fixed part or the mass in the abdomen; There is disturbance of consciousness and convulsion. Special reminder: children under 3 months should seek medical attention as long as they have fever. In terms of medication, children over 6 months old can prepare ibuprofen or acetaminophen at home, and choose one of them. Children under 6 months and over 2 months can prepare acetaminophen without ibuprofen. Children under 2 months generally do not take antipyretics, and they should seek medical advice in time after they have fever.

　　4. How to diagnose and treat patients with cardiovascular disease?

　　The clinical treatment of cardiovascular patients infected with Covid-19 is not much different from conventional treatment.

　　Patients with cardiovascular diseases don’t have to worry too much after infection. The key point is to continue to control basic diseases such as coronary heart disease and hypertension so that their original diseases will not be induced and aggravated.

　　Long-term use of cardiovascular disease prevention and control drugs should not be stopped, which may induce or aggravate the disease. If cardiovascular disease attacks, don’t be afraid and anxious, and be sure to take medicine in time. If you have persistent chest pain, you need to go to the hospital for further diagnosis and treatment.

　　5. Can patients with liver disease take medicine after being positive?

　　Fu Xiaoqing, director of the Department of Severe Hepatology, Xixi Hospital, Hangzhou, said that if you have high fever, headache, sore throat and muscle pain after being infected with Covid-19, you can take nonsteroidal antipyretic and analgesic drugs, such as acetaminophen and ibuprofen. Acetaminophen, also known as paracetamol, may cause liver damage if taken improperly, and even lead to liver failure and death in severe cases, so it cannot be abused. Antipyretic drugs should not be combined with other compound cold preparations, and similar drugs should not be used in combination or alternately. The dosage should be small rather than large, and those who have a history of acetaminophen liver damage should be banned. Patients with liver disease are a special group because their liver detoxification function is limited. Hepatitis B patients who take antiviral drugs orally daily must not stop taking drugs. Those with body temperature over 38.5℃ or obvious body aches can take acetaminophen or ibuprofen appropriately, with fewer doses and times. Those with severe liver disease should seek medical advice in time if they are infected.

XI. Hang Cheng hits directly.

　　1. Where can I find a fever clinic in Hangzhou?

　　"fever clinic inquiry" provides citizens with retrieval and navigation services for medical institutions that carry out fever clinics in Hangzhou. Click on the specific medical institution, and you can also view the busy and idle situation of the fever clinic of the institution, such as the total registration volume of the day, the current waiting number, the current call number and other information.

　　Query path:

　　Zheli Office App: Healthy Hangzhou-fever clinic inquiry

　　Alipay App: health code-fever clinic inquiry

　　Gaode map App: Home search fever clinic

　　2. How to classify the fever clinic in Hangzhou?

　　The first category is positive patients (nucleic acids or antigens). Among them, mild patients are mainly treated according to symptoms, given corresponding drug treatment, generally isolated at home, or voluntarily selected for centralized treatment. Ordinary, severe, critical and patients with severe risk factors are hospitalized in corresponding medical institutions according to their illness.

　　The second category is patients with fever (whether or not they have negative nucleic acid reports within 48 hours). It is up to the doctor to decide whether to do antigen. If the antigen is positive, it needs to be treated in a centralized way before doing nucleic acid. Patients with mild nucleic acid positive condition can go to the centralized isolation point by themselves, and patients with ordinary, severe, critical and serious risk factors can be hospitalized in the corresponding medical institutions according to their illness.

　　3. Can Internet hospitals in major hospitals in Hang Cheng pay and settle accounts with medical insurance?

　　At present, Internet Hospital of Zhejiang People’s Hospital, Internet Hospital of Tongde Hospital of Zhejiang Province, Internet Hospital of Zhejiang Provincial Hospital of Traditional Chinese Medicine, Internet Hospital of Hangzhou Hospital of Traditional Chinese Medicine, and Internet Hospital of Run Run Run Shaw Hospital of Zhejiang University have all opened medical insurance payment and settlement.

　　Internet Hospital of Zhejiang Provincial People’s Hospital: Zhejiang/municipal medical insurance patients can make mobile payment in the Internet Hospital of Zhejiang Provincial People’s Hospital. Medical insurance patients outside the province who can make medical insurance settlement online can also make mobile payment online. Need to be reminded that it is necessary to bind the electronic medical insurance certificate in Alipay/Zheli in advance.

　　Internet Hospital of Provincial Tongde Hospital: At present, the registration fee for online outpatient service of Internet Hospital of Provincial Tongde Hospital is temporarily at its own expense; Online outpatient dispensing can be done at one’s own expense or by medical insurance. If you swipe your medical insurance card, you need to go to the hospital to complete the payment on the self-service checkout machine and get the medicine. Chinese herbal medicine can be delivered by courier and western medicine can be taken to the pharmacy. It is expected that one week later, the Internet Hospital of Tongde Hospital will be able to open mobile payment for medical insurance, becoming the first mobile payment unit for medical insurance in the hospital of integrated traditional Chinese and western medicine in Zhejiang Province, which is universal for medical insurance in provinces and cities.

　　Internet Hospital of Zhejiang Provincial Hospital of Traditional Chinese Medicine: At present, convenient drug purchase, follow-up visit and other related functions have been connected with medical insurance.

　　Internet Hospital of Hangzhou Traditional Chinese Medicine Hospital: The Internet Hospital of Hangzhou Traditional Chinese Medicine Hospital covers all clinical departments of the hospital, such as internal medicine, surgery, gynecology, pediatrics, etc., and many provincial and municipal famous doctors and big coffees that are hard to find even on the first day of peacetime also "join" them. More famous doctors will join in the future. On the basis of the original prescription of western medicine and finished medicine, the upgraded Internet hospital diagnosis and treatment system has added the functions of prescription of Chinese medicine for follow-up visit and distribution of decoction, and also launched a special prescription service. At present, the prescription for quenching thirst, the prescription for eliminating fat, the prescription for gout, the prescription for invigorating spleen and moistening lung, the prescription for nourishing yin and calming liver, the prescription for dispelling cold and removing blood stasis, the prescription for warming yang and the prescription for external use have been launched, all of which are the experienced prescriptions of famous Chinese medicine experts in the hospital. Mobile payment for medical insurance will be opened soon.

　　Internet Hospital of Run Run Shaw Hospital of Zhejiang University: Support medical insurance settlement. 1. Online dispensing is only applicable to patients who return to visit; 2. Online follow-up fees and corresponding drug fees support medical insurance payment (medical insurance payment is only settled in Alipay applet "Run Run Run Shaw Hospital of Zhejiang University"; If you need a refund after medical insurance settlement, only offline refund is supported; If you need a refund, you can contact 4006138688 customer service hotline for a refund); 3. The specific delivery time of drug distribution shall be subject to the distributor; 4. Chinese herbal medicines cannot be prescribed for the time being.

　　4. Hangzhou has started the "fourth needle"! Do you want to make an appointment?

　　At present, the second dose of "booster needle" is mainly aimed at four key groups: 1. People at high risk of infection; 2. Older people over 60 years old; 3. People with low immunity; 4. People with serious basic diseases. If you meet the above categories, you can log in to Zheli Office APP, search for "vaccination" and click "COVID-19 Vaccine" to make relevant appointments. It should be noted that the time interval between the second dose of booster immunization and the first dose of booster immunization is more than 6 months.

　　5, nucleic acid results out, mixed tube positive, yellow code … What should I do?

　　Situation 1: No nucleic acid results.

　　Solution: self-antigen test, upload the results to Hangzhou antigen APP, which will be displayed in the health code interface; Or check the nucleic acid at the sampling point, and the negative result, the health code will be displayed.

　　Situation 2: mixed tube positive

　　Solution: It is suggested that the antigen should be self-checked, and the antigen results should be uploaded to the Hangzhou Antigen APP, or the sampling points should be checked separately. If the results are negative, the health code will be displayed.

Old rumors and new speculation, out of thin air, exaggerating the disaster situation, and cheating for profit … Recently, online rumors have emerged in an endless stream and have been refurbished. How to reduce the living space of rumors? Chongqing Municipal Committee Network Information Office has made a real move! On October 24, the "Chongqing Rumor" series of accounts hosted by the Chongqing Municipal Party Committee Network Office was officially launched. The series of accounts will be launched simultaneously on the five platforms, releasing authoritative rumor information, clearing the source, stirring up confusion and clearing up, actively responding to the concerns of the masses, effectively blocking the spread of online rumors and creating a clear cyberspace.

Weave a "protective net" to refute rumors

Construction of "1541+N" Propagation Matrix

Rumors spread everywhere, and rumors also need the efforts of the whole network. On the 24th, "Chongqing Rumor" opened official accounts on five platforms, namely WeChat WeChat official account, Today Headline, Tik Tok, WeChat Video Number and Weibo, and officially started operation. The five major accounts will not only release authoritative rumor information on the whole network for the first time, but also have the functions of one-click query and clue reporting of rumor content, providing all-round rumor information services for netizens.

Next, the Network Information Office of Chongqing Municipal Committee will also promote the construction of the "1541+N" joint rumor matrix in the city, namely, a Chongqing Internet joint rumor platform, five "Chongqing Rumor" large-scale online accounts, 41 district and county rumor matrices, and a Chongqing joint rumor matrix jointly built and managed by N units, news media, commercial website platforms and other parties, so as to create an authoritative channel for Chongqing to publish rumors, an open window for the masses to participate in cyberspace governance, and a multi-party linkage platform to jointly crack down on online rumors.

Innovate the form of rumors

　　Who can carry it to the end in two hours without fading?

　　The specific evaluation method is to apply a layer of lip glaze normally, wait for 10 minutes to dry and then put on a mask. Then take off the mask immediately to see the instant blooming degree of the lip glaze. The test shows that the six lip glazes are basically uncontaminated when they are just put on the mask, and the instant color locking effect is excellent.

　　After that, the editor applied six kinds of lip glazes and put on a mask for two hours, during which he spoke and drank water normally, and then took off the mask to evaluate the makeup retention of the six kinds of lip glazes, and the results were slightly different.

　　Please see the details below for the specific results:

　　GIORGIO ARMANI Armani Xiaopang Ding dyed lip lotion.

　　Moisturizing chubby cubes are particularly light and thin when applied to the mouth, and the color rendering is super good. When you put on a mask, you can take them off immediately and observe almost 0 smudges. After two hours, I took off my mask. There were some faded masks in some areas, especially at the tip of my lips, but there was no large area of blooming makeup.

　　CHANEL Chanel double-effect color-holding lip glaze

　　Chanel double-effect color-holding lip glaze has two brush heads, one is rich color-developing lip glaze, and the other is transparent gel texture, which is used to cover the lip glaze to enhance moisturizing and color locking. Sure enough, the color locking effect is excellent. When the mask is just painted and put on, the color does not rub on the mask at all. After two hours, the mask is only slightly stained at the lip peak, and the color locking and makeup holding are excellent.

　　NARS matte lip gloss liquid with color retention and fog feeling

　　NARS matte lip gloss liquid with color and fog feeling is extremely moist and rich, which is a matte texture with good coverage. In the immediate contamination test of wearing a mask, only a slight linear smudge is found on the mask. After taking off the mask two hours later, it can be seen that the lip color has some overall contamination, but the degree of contamination is relatively light, and only a thin layer floats on the mask.

　　MAC durable matte liquid lipstick

　　MAC durable matte liquid lipstick is silky and velvet in texture, relatively thick, with excellent color rendering, and quickly forms a film and dries after application. Put on the mask and take it off immediately for observation, almost 0 smudges. After two hours, the contamination at the lip peak is obvious, and there are some slight smudges on both sides of the lips, which may be related to the rich texture of liquid lipstick, or some makeup is removed.　

　　L’Oreal Paris l’ oreal small pen

　　The thin and moist L ‘Oré al small pen is easy to smear, with super hiding power and bright and misty color. When I first put on the mask, there was some slight contamination at the tip of my lips. What is more touching is that after two hours, the contaminated area is only slightly expanded, and the smudge on the mask is not aggravated. The effect of holding makeup and locking color is still very good.

　　MAYBELLINE Maybelline kissing stick

　　Finally, let’s talk about Maybelline kissing stick, which is rich and sticky, but it dries quickly. No matter the test immediately after putting on the mask or taking off the mask two hours later, the mask was not stained with any color and was completely smudged.

　　Let’s take another look at the final result with animation:

　　Have you been planted with grass after reading this issue of beauty lab? Summer is here, put on beautiful lip glaze to get high!

　　At the end of this year, Alipay’s money-making red envelope activity is still in full swing: not only the merchants in offline stores spare no effort to invite everyone to pay with Alipay red envelopes, but also the circle of friends in WeChat is occupied by various news of Alipay red envelopes, and the invitation text messages under the banner of Alipay red envelopes are even uninvited every day.

　　The original intention of this red envelope campaign launched by Alipay is to popularize mobile payment, attract more new users, and at the same time attract a large number of "wool parties" without any suspense. Now, it seems that the "Wool Party" is indeed rich in harvest: according to the screenshots circulated on the Internet, some Alipay users got 1.378 million yuan red envelopes in a short time, and some got 525,000 yuan red envelopes, showing that there are still 100,000+red envelopes on their way.

　　Alipay official said recently that it has been found that some people promote this function through spamming, and even worse, they use [Alipay] as a signature to spamming, which destroys the user’s experience of participating in activities and affects Alipay’s brand image. The Beijing Youth Daily reporter learned that there are currently 800 abusive SMS accounts that Alipay has caught and handled. Alipay will continue to use technical means to prevent and deal with this kind of behavior.

　　Netizens make red envelopes and earn more than 100 yuan a month.

　　On November 15th this year, Alipay announced the launch of the first free red envelope that can make money. According to the activity rules, users can invite other users to use Alipay in the physical store by clicking passwords, QR code pictures, activity posters, links, etc. After success, they can get a reward. Users can generate a tickle password through Alipay APP, and they can share it with WeChat friends, throw it into WeChat group and share it with friends. Friends can copy this tickle password, and then open Alipay to receive a red envelope. When friends pay offline, they use this red envelope, and the owner of the tickle password can also get the corresponding reward.

　　Alipay said that the activity of scanning code to receive red envelopes, that is, "making money red envelopes", was mainly launched for small businesses. When users pay online, merchants can recommend users to scan the code to get red envelopes, and merchants will get corresponding rewards after users use them. The red envelope money received by users and the bounty received by merchants are all borne by Alipay, which is to further popularize mobile payment among small businessmen. At present, there are tens of millions of offline businesses using red envelope codes to promote mobile payment to users, so that more middle-aged and elderly groups and urban and rural residents can accept and use mobile payment.

　　For the majority of users, this Alipay red envelope activity is tantamount to picking up money. Other apps send red envelopes either to invite friends or to register new members. This time, Alipay issued a cash-filled red envelopes without a threshold, without any additional conditions. Just copy it and use it with a brush. Some new Alipay users also found that it is easy to receive a red envelope of more than ten dollars. Even if the red envelope is only a few cents, one per day, it will accumulate over time.

　　People who issue red envelope passwords are also more "ways to make money." Netizen Ms. Wang said that this activity can really make money. For more than 20 days, she has forwarded relevant information through the WeChat circle of friends, and has received nearly 300 bounty so far, earning more than 100 yuan. She can also see who received the red envelope, because it was sent in a circle of friends, so it was basically someone she knew. The lowest is 1.1 yuan and the highest is 3.9 yuan.

　　"Wool Party" made a profit of nearly 1,000 yuan in 3 days by texting.

　　Alipay’s activities are so kind and friendly to users that it naturally becomes a rare gold mine in the eyes of the "wool party".

　　In the last 8 days, the reporter of Beiqing Daily has received 8 short messages about receiving Alipay red envelopes. The sending numbers basically start with "106575" or "10690", and the titles are nothing more than "New Year’s Day Red Packet", "Alipay" and "Alipay Red Packet". Everyone asked to copy the SMS and open Alipay to receive the red envelope. The lowest amount of the red envelope was 200 yuan, and the highest was 888 yuan or 1225 yuan.

　　Almost all colleagues and friends around the reporter received similar text messages, and some received several messages a day. The reporter tried it, and these short messages can indeed receive Alipay red envelopes.

　　In the screenshots circulated on the Internet, some people got a super big red envelope of 1.378 million yuan, while others got a red envelope of 525,000 yuan, and at the same time showed that there were "100,000+"red envelopes on their way. Obviously, this is not something that ordinary "retail investors" can accomplish.

　　According to industry insiders, for the "wool party", using Alipay’s red envelope rules, we can find people to send marketing messages in batches to spread their passwords, so we can wait for red envelopes to roll in at home.

　　Some service providers who provide accurate short message marketing said that they can provide mass designated information services, including the information of Alipay red envelopes. As long as the short message content related to your Alipay red envelope is generated, it can be mass-sent to mobile phone users with designated segments. The price is between 3 cents and 6 cents. If you buy 1 million pieces, each piece costs only 3 cents.

　　Everyone’s current Alipay red envelope messages should be sent by these service providers. Send so many text messages, someone will always copy the red envelope, and the person who sends the text message can take advantage of it. The cost of a few cents each is exchanged for a reward that may be a few cents to tens of dollars. No wonder some people make a profit of nearly 1,000 yuan in just three days.

　　Excessive promotion of the account will greatly reduce the commission.

　　"The message that received the Alipay red envelope was not officially sent by us. We are also deeply disturbed by it. " Regarding the behavior of the "wool party", Alipay responded that Alipay would never encourage this over-promotion.

　　A few days ago, Ant Financial’s open platform issued an announcement that "it is forbidden to use spam messages and other ways to destroy the user experience": "Recently, we found that some people promoted this function through spam messages. We would like to remind you that Alipay will never encourage this over-promotion. If complaints and other adverse effects are caused by harassing users, we will take penalties that are not limited to stopping activities and canceling all rewards. If you use the [Alipay] signature without permission, you need to bear all legal responsibilities arising from it. "

　　It is understood that Alipay is preventing and dealing with it through technical means. Once it is found that someone is harassing users by spamming messages, it will take measures such as greatly reducing the commission to make it unprofitable and even revoking the qualification to participate in the event. At the same time, Alipay has also established a model to analyze improper promotion behavior. When it is found that the behavior characteristics of receiving red envelopes are different from those of receiving normal red envelopes, it will also deal with them. At present, 800 accounts with improper promotion behavior have been found and dealt with.

　　How does the "Wool Party" "bonus hunter"

　　The so-called "wool party" refers to those groups who are keen to participate in various business promotion activities and enjoy preferential benefits. Small to online stores, physical stores, bank credit card promotions, big to mutual gold platform promotion activities, such as interest rate hikes, red envelopes, etc., are all places where the "wool party" shows its talents.

　　"In the morning, I ate ice cream for free with the consumption code sent by the bank, and then I bought 300 yuan goods with 10 points in the supermarket. Credit card for lunch and a big meal at half price. After dinner, I robbed electronic coupons, and 18 yuan watched movies. When going home by subway, use ‘ Scan the code politely ’ I bought two cans of lemon tea on the vending machine, which is 2 yuan in total. I spent a total of 51 yuan today and enjoyed a consumption experience worth 463 yuan. " This is a classic description of the "happy life of the wool party" widely circulated on the Internet.

　　The "wool party" is also divided into genres. Earlier, the "Wool Party" was mainly active in the O2O platform or e-commerce platform, and also specialized in studying bank card concessions. With the development of internet finance in 2015, some online lending platforms often launch some lucrative activities to attract investors, such as registration and certification awards, recharge and cashback, and bid rebates. The "wool party" gradually developed from scattered individuals to groups.

　　In recent years, the "wool party" has increasingly shown the characteristics of specialization, gangs and regionalization. What is even more frightening is that they often wander in the gray area of law and are often only one step away from fraud.

　　In order to facilitate bonus hunter, the "Wool Party" must form a gang, and there are countless social groups of "Wool Party" sharing preferential information on the Internet.

　　How do they cooperate with each other to "bonus hunter"? For example, some P2P online lending platforms stipulate that new users will be presented to 15 yuan after real-name registration, and they can withdraw cash when they are in 20 yuan. QQ group composed of "Wool Party" will release this information from time to time, and make everyone earn enough money in 20 yuan to successfully withdraw cash by signing in, doing tasks and sharing. Generally, the commission for inviting new users to register varies from 5 yuan to 30 yuan. Some people can earn about 1,000 yuan of "wool" every month by registering for cash back and earning commissions.

　　Technical school buys a large number of cheap smartphone registration accounts.

　　After all, it is too slow to "commit crimes" by online groups. The "wool party" will also resort to technical means at great expense, for example, buying a large number of cheap smartphones to register accounts, buying a large number of small mobile phone cards, and successfully realizing the function of receiving verification codes by SMS in batches through some professional software to register and sign in.

　　SMS marketing is also a keen technical means of "Wool Party", but it may also be just a link in the huge industrial chain of "Wool Party". An online survey report on the "wool party" pointed out that in the past few years, the "wool party" has developed into a huge force, which has spawned various gray industries in the upstream, such as code receiving platforms, commercial registration machines, group control systems, agency platforms, information merchants and account merchants. In the whole "bonus hunter" industrial chain structure, mobile phone card vendors belong to the most upstream group.

　　How lethal is the "wool party"? In September 2015, a P2P platform in Guangdong made up its mind to thoroughly investigate the "wool party" and invited external technology companies to monitor it. In a promotion activity, the data provided by the external technical cooperation company showed that nearly 70% of the customers who participated in the promotion activity were "wool party".

　　Industry analysts said that although the Alipay red envelope campaign attracted a large number of "wool parties", it was still different from the P2P platform "bonus hunter". After all, the operation of the "Wool Party" on Alipay red envelopes did not harm the funds of normal users. To some extent, they helped Alipay spread widely. Of course, their short messages do cause harassment to users, but so far, there is no clear regulation on short message marketing. From sending messages in groups to buying mobile phone numbers, there are no clear legal provisions on SMS marketing at present, especially when the information receiver has not suffered property losses but has been harassed, it is difficult to defend his rights. To thoroughly punish the harassment behavior of the "wool party", in addition to the careful consideration of the activists when formulating rules, it also needs the cooperation of all sectors of society.

Poster of Ang Lee’s new work

　 　 Special feature of 1905 film network The winter is getting stronger, and the double eleven is coming again. About ten years ago, this day was named "Singles Day" by netizens led by college students, and it was a melodramatic carnival for the whole people. A few years ago, Ma Yun turned it into a "shopping festival", which was a carnival for all the people. If 2016 is called the first year of high frame rate movies, then this year’s Double Eleven has reason to become a festival related to "120 frames", because this day was officially released.

　

　 　 Before the arrival of this day, "120 frames" has become the most IN-depth industry hot words in recent times. From the early new york test film to the wide praise of the Beijing test film on November 6, these characters with a strong elite atmosphere have almost become synonymous with the "film technology revolution". Strictly speaking, however, the visual revolution brought by Billy Lynn actually comes from the cooPeration of various parameters, and even the single proposal of "120 Frames" is incorrect, because the unit of frame rate is frame /s, or fps, that is, frames per Second … …

Director Ang Lee, joe alwyn and Mason Lee appeared on the red carpet at the premiere of Billy Lynn’s Long Halftime Walk.

　

　 　 If you are not a technical expert, I believe you can look for the fork that closes the page after reading this. Of course, in line with the people-oriented principle of science and technology, the ultimate goal of all film technology innovations will fall on human perception, otherwise it will lose its meaning. So,What different experiences can the new specifications adopted in Billy Lynn’s Long Halftime Walk bring to mankind?And can the perceptual knowledge of audio-visual experience get rid of vague adjectives and find more convincing proof? We consulted some researchers from the medical point of view, trying to get different answers.

　

The charm of afterglow: 24 squares of truth is just an illusion.

　

　 　 For a long time, the frame rate of movies was 24fps, which was derived from a method called "persistence of vision"Physiological phenomenon, this phenomenon has a nice name, calledAfterglow effect. According to Dr. Lei, an ophthalmologist,The human body is a living body full of limitations, such as the visual nerve, which requires a certain reaction time: when light shines on the retina, the resulting image will remain in the brain for a period of time, that is to say, after we see a still photo, even if the photo disappears in reality within a specified time, it has not disappeared in the brain.

Film is actually an "illusion" of human beings.

　 　 Therefore, if we take a group of photos continuously at a certain speed, and then change this group of photos constantly at this speed, our brain will think that we have seen a "moving picture" instead of a group of still photos. Film is such a set of still photos, in other words, it is actually an "illusion" of human beings.

　

　 　 The research shows that when the frame rate of moving images is at least 15fps, the human eye will feel the image continuity; At 25fps, the human eye will not feel the flicker. In the past, movies used 24fps, because it is the minimum standard that can make people think that the picture is coherent under the premise of saving costs. Because of its widespread use, some people call movies ""24 truthfulness”。 The 120fps movie, even if it is played 5 times slower, can still reach the standard of ordinary movies, and the disproof shows the smoothness of its normal speed.

　

　 　 "In fact, the results of the visual persistence function are different in different studies. Some say it is 50 milliseconds, while others say it is 0.1 to 0.4 seconds. This value is limited by other optimistic conditions, such as lighting conditions." According to Dr. Lei’s explanation, we can’t judge the acceptance effect of human eyes simply from the frame rate. Different environments and different principles of image generation will cause different visual persistence time, so the same frame rate has different impressions in movies, TV and computer games.

　

Limitation of human eyes: there is little difference between high and high frame rate.

　

　 　 At first, Peter Jackson adopted the format of 4K and 48fps, which was criticized by many people as "unlike movies like TV". This is because the high frame rate was realized earlier in the field of HDTV than movies, and the general frame rate of TV is 30fps (of course, this is the NTSL standard in the United States, which is 29.97fps, and PAL in China is 25fps), and 120 is the least common multiple of 24 and 30, that is to say, if 120fps can be popularized,

New york Daily News once commented that the high frame rate of 48FPS adopted by The Hobbit is as fake as watching a high-definition football game.

　 　 So, what is the human eye’s ability to distinguish frame rate? "In fact, our eyes are not as sensitive as we thought. Especially in modern society, there are very few people who can use their eyes healthily. Even the most idealized naked eye may not be able to see through everything. As for the human eye’s recognition limit of frame rate, at least in the medical field, there is no universally applicable conclusion. Even if there is, the experimental environment will be different from that when watching movies, televisions and computer screens. "

　

　 　 Dr. Lei believes that the human eye’s ability to recognize 24fps and 120fps is not ideal from a physiological point of view. However, according to the author’s experience of the 3D/4K/120fps version of Billy Lynn on November 6, the clarity and realism of the picture are indeed very different from those of the previous movies with ordinary formats. Dr. Lei’s point of view is: "I believe that increasing the frame rate can improve the visual experience, but can you guarantee that the two experiences are only frame rate changes? Are other technical conditions exactly the same? "

　

　 　 Yes, the 3D/4K/120fps format is a whole. Billy Lynn has brought unprecedented clarity and realism. The resolution of 4K and the projection brightness of 28fl have also contributed, but they are not like 120fps, and the limelight is covered up. The resolution of 4K makes each frame clearer, and the high brightness of the laser projector is obviously more beneficial for us to see what the picture should look like. If these "optimistic experimental conditions" are removed, 120fps will definitely be greatly reduced.

　

Side effects worry: rare and severe dizziness should be controlled for viewing time.

　

　 　 Senior video game players all know that there is a disease that bothers them called "FPS vertigo"When it was released, a word named Avatarheadche was born, which refers to the dizziness caused by 3D movies. Including the VR concept of last year’s fire, the vertigo caused by players in the game has not been perfectly solved so far. Then, when 3D movies appear in the format of 4K and 120fps, will this vertigo be aggravated or alleviated? In medicine, this is also a complicated subject. Dr. Lei said: "Some people are very excited to watch 3D, while others feel like vomiting. Everyone has a different reaction. However, this is somewhat beyond the scope of ophthalmology, and it is related to people’s sense of balance and image analysis ability. "

Avatar set off a revolution in 3D technology.

　 　 In this regard, Dr. Xu, a doctor of neurology, also said that the vertigo caused by 3D movies is complicated and cannot be generalized. "There are roughly two possibilities. One is that because the picture is very realistic and has a strong sense of movement, people’s visual nerves receive motion information, but in fact, when people are sitting in a chair, the vestibular organ in their ears does not perceive motion, and the brain receives two contradictory messages, it will produce a feeling of dizziness. Its purpose is to remind the body. Dr. Xu said that the dizziness in this situation is similar to the principle of motion sickness and seasickness. "But in fact, this reaction of the brain can be changed through repeated adaptation, and it is usually related to the specific visual information content. At least I personally think that not all pictures will give people this illusion, and it is much weaker than the feeling of motion sickness."

　

　 　 "There is another possibility. In fact, when we watch a 3D movie, we will see the so-called ghost without glasses. This is because the stereoscopic effect of the 3D movie is formed by using the distance between the left and right eyes and the difference in viewing angle, and the brain receives two overlapping image information. Sometimes the pupil distance of the glasses does not match the human eye, the images cannot be accurately overlapped, and the focal length of the human eye will become chaotic. However, the brain’s ability to fuse images is limited and has little to do with the clarity of the picture. " At the screening meeting on November 6th, Mr. Bona emphasized the 3D glasses with a cost of $100. This kind of special glasses, together with the image processing in the early and late stages of the film, can effectively solve the problem of image overlap.

　

　 　 Judging from the media comments of the day, it is rare to see the words "dizziness aggravation". This is also closely related to Ang Lee’s attitude towards 3D. First of all, he didn’t blindly pursue huge parallax like when 3D technology was born, and he flew sharp objects to the screen at every turn. Ang Lee has also said many times that 3D made him fall in love with people’s faces and eyes, and this technology is more suitable for expressing dramatic expression tension rather than big action scenes. Therefore, the film as a whole shows the smoothness and smoothness of the lens. Even if we feel immersive on the show and the battlefield, there is no unacceptable shift in perspective, which also forms the comfort that 3D movies should have.

　

　 　 However, from the point of view of eye hygiene, 3D/4K/120fps format does cause some visual fatigue. Dr. Lei said frankly, "The requirements of human eyes on the environment are still relatively high. Too high and too low brightness and clarity will cause fatigue, and long-term fatigue will also cause diseases. But movies are relatively far less than our mobile phones, computers and televisions. After all, ordinary people can’t keep watching movies in the cinema every day, so there are still people in the medical field who are opposed to the popularity of 3D TV, which is also related to the duration. "

　　The Central Meteorological Observatory issued a typhoon blue warning at 18: 00 on May 29: The center of Typhoon Mawar No.2 this year (strong typhoon level) is located on the northwest Pacific Ocean about 640 kilometers southeast of Hualien City, Taiwan Province, China at 5: 00 pm today (May 29), which is 19.6 degrees north latitude and 125.7 degrees east longitude. The maximum wind force near the center is 14 (45 m/s), and the center.

　　It is predicted that Mawa will move to the northwest at a speed of 5-10 kilometers per hour, and approach the east of Taiwan Province. After 31st, it will gradually turn to the north and move to the northeast, and tend to the southern part of the Ryukyu Islands, and its intensity will gradually weaken.

　　Gale forecast: From 20: 00 on the 29th to 20: 00 on the 30th, there will be 6-8 winds in the east of Taiwan Province, bashi channel, Taiwan Province Strait, northeastern South China Sea, southern East China Sea, Taiwan Province Island and its coastal areas, and Fujian coastal areas. The winds in the southeast of Taiwan Province Island and eastern bashi channel can reach 9-10, and the gusts are 11-12. The winds in the sea near the typhoon center can reach 11-14 and the gusts are 15-16.

　　Precipitation forecast:From 20: 00 on the 29th to 20: 00 on the 30th, there will be heavy rain (50-70 mm) in some parts of eastern Taiwan Province Island.

　　Defense guide:

　　1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

　　2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

　　3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

　　4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will.

Special feature of 1905 film network Movies, sharing a better life. The film channel specially launched a series of documentary reports on "This Decade, Our Film Life". In this programme, listen to the movie story of actor and movie fan Lang Jiazi.

Looking back on the past ten years, Sophie chose growth, exploration, conviction, persistence and persistence as the key words to sum up. She feels that they are equally applicable in the past ten years or in the next ten years.

There are many predecessors who have impressed her in the past ten years, and many scenes of "Li Wan" in the movie need to break out. At that time, the director would take her to do a lot of exercises.

For example, yelling at the wall at home, or hammering the wall vigorously, vent all emotions to find the best performance state. "The director taught me a lot." Sophie said.

At school, her acting teacher, Chen Gang, often taught her how to behave. "Being an actor can only be done better by staying pure and original on this road."

Sophie said frankly, I hope the audience will be impressed by the role rather than herself in the future. "I hope that in front of Sophie, I can add the word actor."

Lang Jiazi Mi, 27, is a national intangible cultural heritage and the third generation inheritor of "Face-to-Face Lang" in Beijing.

Ten years ago, Lang Jiazi just went to college. Like many young people, when he graduated from college, he fell into confusion and hesitation.

By chance, he saw a video of his grandfather insisting on handcraft, and was deeply moved by his craftsman spirit, so he made up his mind to take dough modeling as his deep-rooted career.

In the last ten years, outstanding countries have been frequent, and the lion dance with non-legacy themes has made Lang Jiazi very resonant. "What is particularly precious is that after watching this movie, I will feel that the protagonist A Juan is a hero and admire him very much."

It took Lang Jiazi fourteen days to spontaneously create a work of the same name because he liked The Lion Boy. He deliberately added a surreal picture. A Juan went to see the scene of lion dance with her parents when she was a child, and she was skillfully integrated into her works, which made her works warmer.

Mermaid … … Many movies accompanied Lang Jiazi to grow up, and he still remembers them today.

In the past ten years, he has also made many attempts on dough modeling. Jiang Ziya, Xiao Jiu, Ao Bing and Nezha, many interesting characters in movies have become lifelike "face people" through his skillful hands.

"The place where dough is shaped is that regrets in real life or the movie world can be realized through works."

Looking to the future, Lang Jiazi said frankly that he wanted to seek opportunities to bring his favorite traditional handicrafts to the big screen. He expects that traditional handicrafts can come into everyone’s lives and that everyone will have a better understanding of traditional culture! "I’m not doing it alone. This is the energy of inheritance! "

?At present, new energy vehicles are all the rage in the mainland market. It is reported that from January to July 2024, the global sales of new energy passenger cars were about 8.48 million, of which 5.55 million were in China, accounting for 65.5% of the global market share. Therefore, automobile brands that have been deeply cultivated in the domestic market for many years, both independent brands and joint venture brands, are actively deploying new energy fields, and even BMW, an iconic high-end luxury brand of fuel vehicles, is no exception. Today, let’s talk about this 5-series pure electric model launched by BMW at the beginning of this year-and see what its experience is?

?

First of all, in terms of styling, BMW i5 still incorporates some electric elements on the basis of its classic brand image. The shape of the coupe is more popular with young consumers. The front face is still a classic kidney grille with angel eye headlights, and the two sides of the lower enclosure are decorated with L-shaped chrome trim strips, and the BMW i5 is also inlaid with the "I" logo at the closed grille, and there is also a circle of blue lines around the grille, which is different from the fuel version 5 Series.

The vehicle size is 5175x1900x1520 mm and the wheelbase is 3105 mm. Compared with the previous generation, the wheelbase is slightly shorter, but the overall size is longer.

The interior space of the BMW i5 is still very interesting, both in terms of technological attributes and luxury temperament. The configuration of the center console is very simple, with color-changing atmosphere lights and wooden decorative boards.

?

The large-size dual screen of central control, including 12.3-inch full LCD instrument and 14.9-inch central control screen, has a clear display effect and excellent overall impression, and its system fluency is not inferior to that of domestic new energy vehicles.

?

In addition, the number of physical buttons in the BMW i5 car is further reduced, and more touch operation is adopted, which is in line with the trend of the new energy era.

?

The seats of BMW i5 are all wrapped in leather, and the comfort is quite good. Although there is no seat massage, the support is sufficient. Thanks to the wheelbase of more than 3 meters, the rear leg space of this car is quite ample, and the seat filling is soft and the wrapping is good. The mobile phone in the central armrest box charges wirelessly, but it does not support fast charging.

Powered by an upgraded fifth-generation eDrive electric drive system, BMW i5 offers two power versions, eDrive 40 and M60 xDrive. Among them, the entry model is equipped with a rear motor with a maximum power of 340 HP and a peak torque of 430 Nm, with an acceleration time of 6.0 seconds from 0 to 100 km/h and a top speed of 193 km/h; The M60 xDrive with stronger performance is equipped with dual motors, with a maximum power of 601 HP and a peak torque of 820 Nm, and the acceleration time of 0-100km/h is reduced to 3.8 seconds. In terms of battery life, thanks to the 81.2kWh high-voltage battery pack, the pure electric cruising range of BMW i5 can reach 536km to 567km, which is enough to meet the needs of long-distance travel. Moreover, the suspension system and chassis of BMW i5 are also remarkable, which is very stable to control and can also bring a stable and comfortable ride experience to the rear passengers during the driving of the vehicle.

?

On the whole, the BMW i5 is still the BMW in everyone’s mind. It has the design texture precipitated by the BMW family for many years, and it has the temperament that a luxury brand should have, both in appearance and interior. In addition, its localization elements are also doing quite well, and stacking materials in the new energy era is also a full plus. Therefore, BMW i5 will be a good choice for users who want luxury driving experience and a new energy vehicle.
