On December 29th, the Beijing Municipal Health and Health Commission issued the Expert Guideline for Health Management of novel coronavirus Infected Persons in Recovery Period (First Edition).

Remind the public that during the recovery period of infection in Covid-19, although the test results of nucleic acid and antigen have turned negative, the body has not recovered to the pre-disease level, and it will take 1 to 2 weeks or even longer to completely relieve. At this stage, personal protection, daily life, daily exercise, return to work and other aspects should be based on the principle of step by step and do what you can, and gradually return to normal.

Infected in novel coronavirus

Guidelines for health management experts in recovery period

(first edition)

This guideline brings together the opinions of experts and scholars in different fields and summarizes relevant clinical experience, aiming at helping and guiding the self-health management of novel coronavirus infected people in recovery period. If you are infected with Covid-19 and are in the recovery stage, please read this guide carefully and follow it, and be the first person responsible for your health.

First, the applicable population

According to the "novel coronavirus Diagnosis and Treatment Plan (Trial Ninth Edition)" and experts’ suggestions, when novel coronavirus infected people meet any of the following criteria and other symptoms are obviously improved, they have entered the recovery period: 1. Two consecutive nucleic acid tests are negative, and the Ct values are ≥ 35; 2. The results of antigen testing for three consecutive days were negative; 3. After 7 days of isolation at home, the fever symptoms subsided for more than 24 hours without using antipyretics.

Second, the main health problems and rehabilitation suggestions in the recovery period

According to the World Health Organization’s Guide to Personal Rehabilitation in COVID-19, combined with clinical observation and population survey, the convalescent population of Covid-19 infected people currently has the following health problems: shortness of breath, limited physical activity and exercise, physical decline and fatigue, hoarseness and cough, swallowing problems, smell and taste problems, anxiety and depression, sleep problems, physical pain and so on.

(1) Shortness of breath (shortness of breath)

Shortness of breath after infection in Covid-19 is more common. Suggestions on the problem of shortness of breath: You can try various postures to relieve shortness of breath to determine which one is effective.

Prone position: lying flat with the abdomen down (prone position) can help relieve shortness of breath;

Leaning forward: Sit next to a table, leaning forward above the waist, with your head and neck on the pillow on the table, your arms on the table, or sitting in a chair, leaning forward, and your arms on your knees or chair armrests;

Leaning forward for standing position: in standing position, lean forward and lie on the windowsill or other stable supporting surface;

Stand with your back leaning against the wall, with your hands at your sides, your feet about 30cm away from the wall, and your legs apart.

In addition, we should pay attention to the following situations that need timely medical treatment: after slight activity, there is very obvious shortness of breath, which cannot be improved after adopting any posture to relieve shortness of breath; The degree of shortness of breath changes at rest, and it cannot be improved after using any breathing control technology; Feeling chest pain, rapid heartbeat or dizziness during certain postures, activities or exercises; There is weakness in the face, arms and legs, especially on one side of the body.

(2) Cough

Cough is an important defensive reflex of the body, which is beneficial to remove respiratory secretions and harmful factors.

Suggestion on cough: general mild cough can be treated without treatment. If phlegm is too much or difficult to cough up, you can take acetylcysteine, ambroxol hydrochloride, eucalyptus citrulline capsules, carboxymethyl stane and other expectorants. If the cough is mainly dry cough, you can take dextromethorphan, compound methoxyphenamine capsules and antihistamines.

In traditional Chinese medicine, if there is throat pain or cough (especially dry cough) and there are no other symptoms, you can take Jingfangbaidu powder, Yinqiao powder and Sangju drink to turn heat into fluid, moisten the lungs and relieve cough, and you can also use external treatment methods such as scrapping. If the cough is serious, affects daily work or sleep, or lasts for more than 3 weeks, it is recommended to go to the hospital for treatment.

(3) fatigue

Feeling weak or consciously tired, with no obvious relief after rest, is the most frequently reported symptom in the recovery period of Covid-19 infection.

Suggestions on fatigue: keep the rhythm of daily life, determine the priority of activities, and make a reasonable work plan. Symptoms are mild and there is no dyspnea. Routine treatment of basic diseases can be accompanied by appropriate treatment of qi-invigorating drugs, such as lily and platycodon grandiflorum, which can replenish lung qi and promote qi-flowing. If dyspnea cannot be relieved, you need to go to the hospital in time.

Traditional Chinese medicine external treatment methods such as soaking and washing can be used. Take 3 slices of ginger (about the size of a one-yuan coin), add 5 grams of moxa and 5 grams of salt, boil for 10 minutes, add water above the ankle joint, control the temperature at 40-43℃, and keep this temperature for about 30 minutes, once a day. It is advisable to sweat slightly, not to sweat profusely. If you have heart disease, the soaking time needs to be halved, and it must not be too long. If dyspnea cannot be relieved, you need to go to the hospital in time.

(D) Insomnia

Symptoms such as difficulty in falling asleep, short sleep time, shallow sleep, and dreaminess may appear during the recovery process of Covid-19 infection.

Suggestions on insomnia: sleep and get up regularly. Make sure there are no distractions in your environment, such as excessive light or noise; Try to stop using electronic devices such as mobile phones and tablets one hour before going to bed; Minimize the intake of nicotine (such as smoking), caffeine and alcohol; Try relaxation techniques to help you fall asleep, such as meditation, mindfulness decompression therapy, thinking or bathing, aromatherapy, Tai Chi, yoga and music. You can also use traditional Chinese medicine to soak and wash.

(5) Pain

In the process of Covid-19’s infection and recovery, there are often pain manifestations such as bone and joint pain, muscle soreness and sore throat.

Suggestions on pain: For joint, muscle or whole body pain, you can take analgesic drugs such as paracetamol or ibuprofen with meals. For sore throat, you can use Jin Houjian, mint buccal tablets and other drugs to treat it. A good sleep helps to relieve the pain symptoms. Listening to relaxing music or meditation can also help relieve pain. Adjusting the rhythm of daily activities is one of the keys to controlling pain. You can also use hot compress, scraping and other external treatments of traditional Chinese medicine. If you have obvious chest pain, you should go to a medical institution in time.

(6) palpitation

In the rehabilitation stage of Covid-19 infection, some patients have symptoms of palpitation and palpitation. At this time, it is suggested that we should pay more attention to rest, adjust our daily routine, keep enough sleep, and at the same time, we should strengthen our own nutrition and eat more foods rich in protein and vitamins to improve the body’s disease resistance. If the symptoms of palpitation are obvious, the pulse lasts more than 100 times per minute and less than 60 times, or irregular pulse occurs, it is necessary to be alert to the occurrence of viral myocarditis. It is recommended to go to the hospital for examination in time to find out the cause and take measures.

(7) Sound problems

Covid-19 infection can cause sore throat, irritating cough and the feeling of phlegm accumulation in the throat, so it is necessary to clear your throat frequently. There may also be a weak voice, wheezing or hoarseness, especially after using a ventilator in a hospital.

Suggestions on sound problems: replenish enough water and inject water several times a day to keep the sound as normal as possible. Don’t make your voice tense. Don’t speak in a whisper, because it will strain the vocal cords, and try not to speak or shout loudly. Inhale steam (cover your head with a towel and inhale steam from a cup filled with boiling water) for 10-15 minutes, which can relieve dryness and moisten the vocal tract. It is recommended to stop smoking.

(VIII) Swallowing problems

It is difficult to swallow food and drink because the muscles that help swallow may be weakened.

Suggestions on swallowing: keep your body straight when eating and drinking, and never eat or drink lying down. Stay upright (sit, stand, walk) for at least 30 minutes after meals. Try foods with different textures. You can choose soft, smooth or moist foods, or cut solid foods into very small pieces to eat. You should chew slowly when eating, and don’t wolf it down. Pay attention when eating or drinking water. Try to choose a quiet place to eat. Avoid talking while eating or drinking water. Make sure there is no food in your mouth before eating or drinking a bite. If necessary, swallow once first. If you feel tired after eating a whole meal, you can eat less and more meals in a day. Keep your mouth clean by brushing your teeth and drinking water. If you cough or choke when eating or drinking water, please consult a medical staff, because food or drink may have entered your lungs by mistake.

(9) Decreased sense of smell and taste

If the sense of smell or taste declines, it is recommended to try the following: brush your teeth twice a day to ensure oral hygiene. Conduct olfactory training, including smelling lemon, rose, clove or eucalyptus twice a day for 20 seconds each time. Try adding herbs and spices to food, such as lemon juice and fresh herbs. Most sense of smell and taste decline and will recover within one month after Covid-19 infection.

Third, psychological adjustment and nutritional support in recovery period

(A) psychological debugging in recovery period

In the process of Covid-19’s infection and recovery, it is natural to feel fear, tension and anxiety, so there is no need to be overly nervous. To overcome fear, tension and anxiety, we can start from the following aspects:

1. To keep a regular schedule, ensure adequate sleep, moderate exercise, reading, listening to music, etc., and ensure a healthy diet. Don’t take negative coping styles, such as denial, avoiding retreat, relying too much on others, accusing and complaining, transferring emotions, losing temper, impulsiveness, etc., especially don’t try to relieve tension through alcohol and tobacco.

2. Actively carry out psychological adjustment, communicate with others, encourage each other, support each other psychologically, and divert attention.

3. Breathing relaxation training, aerobic exercise, mindfulness meditation and meditation can be carried out to adjust emotions.

(2) Nutritional support in recovery period

You can eat a small amount of meals, pay attention to the regular and quantitative diet, and the food is diverse and reasonably matched. Keep the variety of food, pay attention to both meat and vegetables, and match the thickness; Eat more fresh vegetables, fruits, soybeans, milk and cereals; Eat fish, poultry, eggs and lean meat in moderation, preferably fish, shrimp, poultry and lean meat, and eat less fat. The diet is light and not greasy. Avoid spicy and irritating foods and fried and greasy foods. To ensure the amount of drinking water, boiled water is the first choice, and sugary drinks are less or not.

Rational use of medicinal diet for food maintenance and dietotherapy, combined with the winter climate characteristics, it is recommended to use traditional Chinese medicine dietary therapy such as Sydney Siraitia grosvenorii water, corn silk orange peel water, white radish honey water, walnut onion and ginger soup, pear soup, yam, melon and lotus seed porridge, coix seed and poria cocos yam porridge.

Fourth, matters needing attention in daily life

During the recovery period of Covid-19 infection, although the test results of nucleic acid and antigen have turned negative, the body has not recovered to the pre-disease level, and it will take 1-2 weeks or even longer to completely relieve. At this stage, personal protection, daily life, daily exercise, return to work and other aspects should be based on the principle of step by step and do what you can, and gradually return to normal.

(1) Matters needing attention in daily life

1. At present, it is in the period of high incidence of respiratory infectious diseases in winter, and the risk of overlapping epidemic of Covid-19 infection with influenza, common cold and other respiratory infectious diseases in winter and spring cannot be ruled out, and the standard of self-protection cannot be lowered because of "Yang Kang". When going out, we should continue to wear masks scientifically, reduce gathering, and do not go to crowded places and closed spaces unless necessary. Hand hygiene should be done at all times, especially after contact with suspicious pollutants or the surface of public objects with high frequency.

2. Ensure adequate nutrition, regular work and rest and good sleep. Pay attention to eating more high-protein and nutritious food in diet. Smoking and drinking habits, especially those with risk factors, will aggravate the basic diseases. It is suggested that it is best to quit smoking and limit alcohol after "Yangkang". For those who have a bad appetite or taste disorder after "Yangkang", it is recommended to eat less and eat more meals. Diabetic patients should keep a regular diet to avoid large fluctuations in blood sugar.

3. After the symptoms of acute fever subside, you can take a bath if your physical strength allows, but you should avoid steaming sauna. When bathing, you must avoid catching cold, pay attention to the indoor temperature, and the bath water temperature should not be too high.

(2) Matters needing attention in daily exercise

1. On the basis of regular daily life, ensuring adequate nutrition and sleep, start with low-intensity activities, such as walking, eight-segment brocade, simple daily housework, etc. If there is no obvious discomfort, you can gradually increase the intensity of activities within a few weeks, such as going up and down stairs, brisk walking, jogging, cycling, swimming and dancing until you return to your normal activity state before you get sick.

2. If you have chest pain, palpitation, dizziness and other uncomfortable symptoms during exercise, you should immediately stop exercising and seek medical advice if necessary. For hospitalized rehabilitation patients, patients with original cardiopulmonary diseases and patients with symptoms such as fatigue, chest tightness and dyspnea, strenuous exercise or heavy work should be avoided within 2 weeks, and low-intensity exercise can be maintained for at least 1-2 weeks, and then higher-intensity exercise should be carried out after the body gradually adapts.

(III) Matters needing attention in returning to work

1. At the beginning of returning to work, start from the lighter work and gradually return to the normal workload and working state to avoid nervousness, overtime, staying up late and other behaviors.

2. If possible, take a lunch break for 20-30 minutes.

3. Because there are differences in individual constitution, age and illness, there will be differences in recovery time, so the recovery work is gradual, and the intensity is based on not feeling tired.

V. Suggestions on home disinfection

Covid-19 infected people should strengthen indoor ventilation after entering the recovery period, and disinfect key areas and used items on the basis of cleanliness and hygiene. Physical disinfection methods such as sun exposure and heat are preferred as disinfection methods, and chemical disinfectants can be used to wipe the surface of home environment. Disinfectants, such as chlorine-containing disinfectants, quaternary ammonium salt disinfectants, hand disinfectants, etc., can also be used to disinfect wet wipes with alcohol or quaternary ammonium salt.

(A) disinfection methods for different objects

1. Indoor air. Open the window regularly every day to keep indoor air circulation. If there is no natural ventilation condition, mechanical ventilation can be carried out by exhaust fan and air conditioning system.

2. the surface of the object. When there are pollutants on the surfaces of tables, chairs, furniture, door handles, faucets, etc., clean them first, and then wipe them with 500mg/L chlorine-containing disinfectant. You can also choose quaternary ammonium salt disinfectant with little irritation, and clean them with water after 30 minutes. Small items such as mobile phones, remote controllers and mice can be wiped and disinfected with alcohol wipes.

3. Surfaces such as the ground and walls that may be polluted. If there are pollutants, they should be completely cleaned before disinfection, and can be wiped or sprayed with 500mg/L chlorine-containing disinfectant for disinfection, and the disinfection time is not less than 30 minutes.

4. Dining (drinking) utensils. First clean and then disinfect, preferably boil and disinfect for 15 minutes, or soak in 500mg/L chlorine-containing disinfectant for 15 minutes, and then clean with water.

5. Textiles such as clothes, bedding and towels. It can be boiled and disinfected for 15 minutes or washed with heated water, and kept above 56℃ for 30 minutes. It can also be soaked in 1000mg/L quaternary ammonium salt disinfectant or other clothing disinfectant for 30 minutes, and then cleaned as usual. For fabrics that can’t be washed with water, they can stand at room temperature for 7-10 days.

6. Sanitary appliances such as mops and rags. It should be used exclusively in the special area to avoid cross-cutting. After use, it should be soaked and disinfected with 1000mg/L chlorine-containing disinfectant, rinsed with clean water after 30 minutes, and dried for storage.

7. the bathroom. After the toilet seat cushion and its surroundings can be cleaned, wipe and disinfect with disinfectant containing 1000mg/L-2000mg/L of available chlorine, and wipe and disinfect toilet door handles, faucets, hand-washing countertops and other parts that are often contacted by hands with disinfectant containing 500mg/L of available chlorine. After 30 minutes, wipe them with clean water to strengthen the exhaust of the toilet.

8. Refrigerators and frozen foods. If the frozen food stored in the refrigerator is polluted, it is recommended to treat it as garbage; If you need to eat it, you can also eat it after it is cooked thoroughly. During the food processing, do a good job of personal protection, wear masks and gloves, and strictly observe hand hygiene. If the inner wall of the refrigerator is polluted, it is suggested to refer to the disinfection method of "object surface" after the temperature in the refrigerator returns to normal temperature.

9. Domestic garbage. Garbage should be collected and cleaned in time. It is suggested that the outer surface of the garbage bag should be sprayed with chlorine-containing disinfectant containing 500mg/L-1000mg/L of effective chlorine after the double-layer plastic bag is tightly bound, and then transported to the garbage dropping point.

10. Other items. Articles that are not suitable for disinfection, such as books and valuables, can be treated by sealing and standing at room temperature for 5-7 days.

(2) Precautions related to disinfection

1. Disinfectant should be prepared now. Take a chlorine-containing disinfectant with the effective chlorine content of 5% as an example: when preparing 500mg/L, take 1 part of disinfectant and add 99 parts of water to mix well; When preparing 1000mg/L, take 1 part of disinfectant, add 49 parts of water and mix well.

2. Disinfectants, especially chlorine-containing disinfectants, are irritating to some extent, so personal protection should be paid attention to when preparing and using them, and splash to eyes should be prevented. At the same time, the disinfectant is corrosive to a certain extent, so it should be wiped with clean water after reaching the disinfection time to prevent damage to articles.

3. Disinfectant should be used alone and not mixed with other chemical components. Before use, read disinfection products’s instructions carefully and use it correctly in strict accordance with the scope of use, method of use, action concentration and action time specified in the instructions.

4. Disinfection at home should be scientific and standardized, avoiding over-disinfection, not directly using disinfectants to disinfect the human body, not disinfecting indoor air under manned conditions, not using alcohol to disinfect the air, and not carrying out large-scale disinfection.

5. Disinfectant should be stored in a cool and dark place to avoid children’s touch.

Six, the key population health guidance

(a) the elderly

1. Old people often still have a certain degree of fatigue after the nucleic acid or antigen turns negative, even lasting for several weeks. If you feel tired, please rest as much as possible. Try to adjust the daily pace of doing things and don’t do too many things at once.

2. If energy permits, please ask your old friends to gradually resume your daily routine and make a daily schedule for yourself, including sleeping, eating and activities.

3. Exercise safely and without fatigue to restore strength and endurance. If walking is difficult for you, consider exercising on the bed or chair, starting with stretching, and gradually increasing the amount of activities, such as doing housework, walking, Tai Chi, Ba Duan Jin and so on. When you start exercising, start with 5-10 minutes, and then add one minute every day. If you are worried about falling, please exercise when you have family or friends. If you feel dizzy, chest pain or dyspnea during or after exercise, please stop to rest and consult your doctor.

4. Drink 1500-2000ml of water every day, three meals a day are not lacking, and you can add meals appropriately. It is recommended to record daily food to help you know whether you are eating healthily.

5. Keep in touch socially. Talk to relatives and people you trust by phone, video call or other means of communication as much as possible every day.

6. Try to think three happy things every day, try to repeat the words "relax" and "calm" when taking a deep breath, and try to avoid negative or unhealthy thoughts; If stress, worry, fear and sadness interfere with daily activities for several days, please contact your doctor for psychosocial support.

7. List emergency telephone numbers: such as the telephone numbers of nearby medical institutions, social and psychological support helplines, family doctors, family members and friends.

8. After the elderly with basic diseases are infected with Covid-19, the basic diseases will get worse. For example, elderly people with hypertension may have unstable blood pressure after infection, elderly people with diabetes may have unstable blood sugar after infection, elderly people with cerebrovascular disease may have the risk of cerebral infarction or bleeding after infection, and elderly people with chronic obstructive pulmonary disease may have cough and dyspnea after infection. The elderly turn negative after treatment with nucleic acid or antigen test, but the aggravated basic disease may not be stable with it, so it is necessary to closely monitor blood pressure, blood sugar, finger oxygen saturation, etc. If the condition is unstable for a long time, please go to the hospital in time and adjust the treatment plan for the basic disease.

(2) Pregnant women

1. No matter what gestational age, pregnant women should pay attention to rest within 1-2 weeks after recovery from Covid-19 infection, and can take appropriate exercise, but the intensity of exercise should not be too large, and the time should not be too long, step by step. Warm up well before exercise, and replenish water properly before and after exercise. If threatened abortion, placenta previa and other conditions are not suitable for exercise, you should follow the doctor’s advice.

2. Pay attention to ensure reasonable and adequate nutrition intake throughout pregnancy.

3. To maintain a happy mood and emotional stability, there is no need to worry too much about the adverse effects of Covid-19 infection on the fetus. At present, it is considered that the probability of intrauterine infection caused by vertical transmission of Covid-19 to the fetus is extremely small, and generally it will not lead to malformation.

4. Pregnant women should have regular pregnancy tests, and pregnant women in the second and third trimesters should monitor their own fetal movements. If you have abnormal fetal movement, abdominal pain, abdominal discomfort, vaginal bleeding and other symptoms, you should go to the hospital immediately.

(3) Children and adolescents

Generally speaking, most children and adolescents infected with Covid-19 have a good prognosis, showing a self-limited course of disease, and the probability of serious complications and sequelae is extremely low. Parents should first keep a calm mind, understand the natural course of Covid-19 infection, and not be overly anxious.

1. Continue to do a good job of protection and develop good hygiene habits.

(1) Don’t take children and adolescents to crowded places, poorly ventilated rooms or contact with others for a long time. Wear a mask when going out (children over 3 years old) and try to keep a distance from others.

(2) When staying at home for a long time, indoor ventilation should be done. Try to choose ventilation when children and adolescents go out for activities, or ventilate each room separately.

(3) After going home, family members should wash their hands, wash their faces, change clothes, and then get in touch with their children. If there are respiratory tract infections at home, they should be isolated from their children and wear masks.

(4) Guide children and adolescents to develop good hygiene habits, and wash their hands before and after meals, after sneezing, coughing and cleaning their noses, and after going out.

2. Develop good living habits and enhance your own resistance.

(1) Regular work and rest and adequate sleep. Go to bed and get up on time, sleep at least 12 hours a day within one year old, 11 hours before kindergarten, 10 hours in kindergarten, at least 9 hours a day for primary school students and 8 hours for middle school students.

(2) Step by step, exercise. After Covid-19 recovered from infection, it is suggested that outdoor activities and physical exercise should be gradually increased, and the intensity should be suitable for children without discomfort.

(3) Regular meals and balanced diet. Do not be partial or picky about food, and cultivate healthy eating habits.

(4) Others: reasonably increase or decrease clothes and pay attention to mental health.

3. Correctly treat the recovery symptoms. Some children and adolescents will continue to cough for some time after Covid-19 infection. If the general situation is good, it does not affect daily life and does not need special treatment, it is usually not recommended to use antitussive drugs. However, if the child originally had bronchial asthma, allergic rhinitis, etc., and the cough time was not recovered for more than 3 weeks, and the cough was mainly at night, he should also seek medical attention in time.

4. Parents should be vigilant against high-risk groups such as congenital heart disease, chronic lung disease, nervous system disease, severe malnutrition, tumor, obesity, diabetes or hereditary diseases, immunodeficiency or long-term use of immunosuppressants, premature infants or newborns. When the child continues to have high fever for more than 3 days, shortness of breath, listlessness, persistent chest tightness or chest pain, or the condition worsens, he should seek medical attention in time.

The 28 pillars at the south gate of the memorial symbolize the Communist Party of China (CPC)’s 28-year struggle from the founding of the Party to the establishment of a new China.

Pay attention to the protection of ancient trees during the construction of memorial hall.

The second floor of the east gate of the memorial hall is designed with four beams and eight columns.

The preface hall of the solemn and magnificent memorial hall.

The facade of the memorial hall is made of gold rust stone.

　　Upside down and generous! "Beijing ‘ Catch the exam ’ " "Entering Xiangshan", "Continuing to command the liberation of China", "Preparing for the construction of a new China" and "Do not forget your initiative mind keeps in mind its mission and strives forever" are solid steps for the people of the Communist Party of China (CPC) to advance all the way in the past 70 years.

　　In the past few days, if you have been to the foot of Xiangshan Mountain, you must have heard of this magnificent history and seen a building built to inherit and remember this red memory — — Xiangshan revolutionary memorial hall. The Xiangshan Revolutionary Memorial Hall, covering an area of 2.4 hectares and a building area of 17,985 square meters, is an ancient and new building. With modern technology and traditional elements such as sloping roof and bucket arch, it is more solemn and solemn, and it also adheres to the concept of green thrift. The pattern of depending on the mountain makes the building grow naturally in the mountains and forests, and it is as natural as the environment, just like a beauty. If one point is increased, it will be long, and if one point is reduced, it will be short.

　　How on earth was this building completed? The Beijing Evening News reporter made a special visit to record the bit by bit of the Xiangshan Revolutionary Memorial Hall.

　　Memorial hall pattern

　　At 13: 00 on September 11th, taking advantage of lunch break, worker Han Kai walked to the Xiangshan Revolutionary Memorial Hall at the foot of the mountain, and went up the stairs from the East Square. He pointed to the stones under his feet and said softly, "They are all whole, and there is no ‘ Broken live ’ " Under the corners of my mouth, I can’t hide my pride.

　　Breaking is a jargon in engineering, which means that there is no place that is cut into small pieces of stones. This detail, which is basically impossible for ordinary people to notice, is precisely the gap between high-quality projects and ordinary projects.

　　■ Reduce the volume

　　Three sides are embedded underground with the terrain.

　　Xiangshan, 557 meters above sea level, has many historical sites, and pavilions are scattered among the mountains like stars. The newly completed Xiangshan Revolutionary Memorial Hall, just like growing out of the mountains, is natural with the surrounding environment. People standing on the street looking east can only see the sloping roof surrounded by green trees and a faint half-story facade, and they can never imagine that there is a world under the green trees.

　　"This is to use the height difference of Xiangshan itself to make the whole building embedded in the mountain." Zhuang Weimin, the chief designer and dean of the School of Architecture of Tsinghua University, told the reporter that Xiangshan, located in the area of three mountains and five gardens, belongs to a scenic spot in Beijing. From the perspective of urban planning, all buildings must follow the "moderate reduction". "How can a Xiangshan Revolutionary Memorial Hall with an area of nearly 18,000 square meters be integrated with the environment? We borrowed the method of blanking, so that the south, north and west sides are embedded into the ground with the terrain, and the fifth facade formed by the sloping roof, thus resolving the sense of awkwardness brought by the volume and outline of the building. "

　　■ profound meaning

　　Building Four Beams and Eight Columns for New China

　　While reducing the building volume, Xiangshan Revolutionary Memorial Hall has also formed two unique axes. From the exhibition hall to the South Square, it is spread along the north-south axis, facing south, creating a sense of ceremony of traditional memorial buildings in China. From the entrance of the audience to the West Square, it is spread along the east-west axis, sitting west to east, looking at the incense burner peak in the west and facing the Beijing City in the east, which is convenient for the audience’s activities, and also conforms to the history of the CPC Central Committee’s "going to Beijing to take the exam" and liberating all China in Xiangshan.

　　There are many similar meanings. The canopy shape of "four beams and eight pillars" implies that the CPC Central Committee built four beams and eight pillars for the new China in Xiangshan. The 28 colonnades symbolize the Communist Party of China (CPC)’s 28-year struggle from the founding of the Party to the establishment of a new China. On the South Square stands the flag pole with a height of 19.49 meters, which means that People’s Republic of China (PRC) was born in 1949.

　　Memorial hall jiangxin

　　Metal carved bucket arch, four-beam and eight-column dome, antique Han-Tang pottery tile, semi-new and semi-old dry-hung stone, natural courtyard with ventilation and light transmission & HELIP; … As a newly completed modern and contemporary building, the Xiangshan Revolutionary Memorial Hall is full of simple and solemn traditional beauty.

　　■ Respect for tradition

　　Traditional elements are integrated into modern techniques

　　"Architecture should respect tradition and nature, and form a natural relationship with nature." Zhuang Weimin said, taking the dry hanging stone on the facade as an example, the design team has done a lot of research on what material to choose, and compared several domestic stone materials, such as gold rust stone, golden hemp, Suizhou yellow stone and Kaman stone, and chose the most suitable gold rust stone.

　　Of course, respecting tradition does not mean 100% conformity. The reporter noticed that although the elements of the arch and cornice are traditional and historical, the material of the arch and the pattern of the cornice are all new techniques. Here, the traditional wooden materials are replaced by modern aluminum alloy and stainless steel, with a more stable structure, a deeper tone and lower cost. Only the main gate retains the brass commonly used in ancient buildings, so that the audience can feel the continuation of time in touch.

　　■ Careful everywhere

　　Practicing economy and choosing antique pottery tiles

　　"In order to produce these 58,000 pieces of antique Han and Tang pottery tiles for the roof, it is really not easy to go back and forth." Liu Xionggeng, deputy manager of the decoration of Xiangshan Revolutionary Memorial Hall of Beijing Urban Construction Group, remembers that copper tiles were considered at first, but considering the high cost, pottery tiles with the same effect but more economical were selected later. Then, the color that is most suitable for the environment is selected from the three alternative colors.

　　Set the color, mass production is also a particular job. The factory producing pottery tiles is located in a small town under the jurisdiction of Foshan City, Guangdong Province. The simple hotel in the town is 6 kilometers away from the factory site. Every day, Liu Xionggeng rides three hops between the hotel and the factory, and stays for 31 days. Appearance, strength, arch height, diagonal, every time the mold is fired, Liu Xionggeng will pull a ruler to test each value one by one, and any unqualified one will have to be returned to the furnace and rebuilt. In this way, after repeated firing for six or seven times, the satisfactory mold can be considered before entering the mass production stage. "Because we were worried about damage in transportation, we gave up the usual land transportation and changed to water transportation. We transported Taowa to Tianjin Port first and then pulled it back to Beijing from Tianjin."

　　The same is true of stone production on the facade. 16,000 square meters of gold rust stone are prefabricated and pasted in the factory, and then pulled to the engineering site for hanging. "Among them, the largest stone has an area of 2.5 square meters and consists of 8 sub-parts." Liu Xionggeng told reporters that the bonding angle of stone can be varied, 90 degrees, 110 degrees, 130 degrees, 135 degrees, 160 degrees … … Every angle must be exactly the same, otherwise it will not be straight when pasted together. "In the factory, we first make a model wall according to the full-scale ratio, and every stone in the wall is numbered one by one." Liu Xionggeng said that from 58,000 pieces of Han and Tang pottery tiles and 104 metal arches to 16,000 square meters of dry hanging stone, 3,600 square meters of glass curtain wall and Xiangshan Revolutionary Memorial Hall, every material in the project can be described as elaborate.

　　Memorial Hall Wisdom

　　In addition to care and care, engineering construction is also inseparable from wisdom. At the same time, in line with the concept of being green, frugal and close to the people, Xiangshan Revolutionary Memorial Hall also attaches great importance to green and energy conservation in its construction.

　　■ Strict control

　　600 columns are cast at one time.

　　Liu Kuisheng, the project manager, told the reporter that when the structure of Xiangshan Revolutionary Memorial Hall was under construction, it was in the peak season of tourism, and tourists came to Xiangshan in an endless stream, reaching 100,000 at the peak of daily passenger flow. In order not to affect tourists, the construction will be carried out at night. "In the earthwork excavation, in order to save time, we adopted ‘ Dig the heart ’ Tactics, excavation from the center, slope support around, and double-row piles as supporting structure. "

　　Due to the limited area of the site, the construction site was completely occupied by construction equipment, so the project department adopted sports warfare, "shooting one gun for another place", the office area was moved three times, the road was changed every few days, and the material processing shed was arranged wherever there was open space. "The raw materials came in in the middle of the night, and the inspection was also completed in the middle of the night, and nothing happened in the whole process ‘ Waiting for people ’ The situation. "

　　At the same time, as a project with a design service life of 100 years, in order to ensure the bearing capacity and the durability of the century-old building, 4,500 tons of steel bars and 26,000 cubic meters of concrete are used in the structure of Xiangshan Revolution Memorial Hall. "The diameter of the main reinforcement of the column is 32 mm, and the design is particularly dense. There are more than 70 steel bars in the most column." Liu Kuisheng said that it is not difficult to pour a column with a cross-sectional diameter of 1.2 meters and a height of 8 meters. In addition, it is often constructed at night, and the lighting conditions are poor. If you are not careful, quality problems will occur. "Under the strict control of the project department, more than 600 columns are all poured at one time, and no quality problems have occurred."

　　In order to build a high-quality project, builders never complain about hardship and tiredness. Chen Yanjun, who is taking wedding photos in Hangzhou, went to Beijing without saying anything. Rao Ze, who was newly married, left his pregnant wife at home and lived and ate at the construction site. When his wife was hospitalized with an operation on her right lung, Liu Xinwen only stayed with her for one day and then returned to the construction site to continue her work.

　　■ "Give way" ancient trees

　　The whole memorial hall moves 5 meters eastward.

　　It is understood that the building materials used in the construction of Xiangshan Revolutionary Memorial Hall, even small and micro materials including a small nail, are all domestic products; Earthwork uses local materials, and about 70% of the excavated earthwork is reused on site, which not only saves materials but also avoids dust. The air conditioning system adopts frequency conversion speed regulation and self-sensing temperature control, while the lighting system adopts intelligent control and LED energy-saving lamps.

　　There is also the protection of trees. Zhuang Weimin introduced that since the beginning of the design, the team has made a detailed investigation on all the trees in order to preserve the original ecology as much as possible. In order to protect several ancient trees such as Pinus tabulaeformis and Luanshu, the whole building has moved 5 meters to the east. "When we first entered the site, there were more than 400 trees in the foundation pit on the east side, including 136 precious Eucommia trees and more than ten ancient trees such as Luan tree, Sophora japonica and Pinus tabulaeformis."

　　Liu Kuisheng also remembers that in order to protect these more than 400 trees, everyone was cautious, and everything that could not be moved was not moved, and everything that had to be moved was transplanted to the maintenance base within 48 hours. It is also thanks to this that the audience who enter the Xiangshan Revolutionary Memorial Hall can see a green landscape from mountains, lawns, water gardens to courtyards.

The Ministry of Commerce introduces the relevant information of the Implementation Opinions on Supporting Export Products to Domestic Sales-
Help enterprises solve the problem of domestic sales and promote the effective penetration of domestic and foreign trade

On June 30th, the Ministry of Commerce held a special online conference to introduce the implementation opinions on supporting export products to domestic sales recently issued by the General Office of the State Council. Yang Guoliang, deputy director of the Foreign Trade Department of the Ministry of Commerce, said that in the short term, supporting export products to domestic sales is an emergency measure to help foreign trade enterprises solve the problem of domestic sales and promote the basic stability of foreign trade. In the long run, supporting the export products to domestic sales is also a long-term way to promote the effective integration of domestic and foreign trade, make full use of the domestic and international dual cycle, and cultivate new advantages in participating in international cooperation and competition.

According to a survey conducted by the Ministry of Commerce, foreign trade enterprises also face some difficulties in transferring to domestic sales, mainly because some products have different standards at home and abroad. For example, the size of clothing exported to Europe and America is different from the domestic standard, and the style is also different from the domestic market demand. The export of some export products to domestic market often involves brand and trademark issues and needs to be authorized by the foreign party. Some foreign trade enterprises produce according to orders for a long time, lack domestic marketing experience and specialized teams, and their brand awareness is not high.

Yang Guoliang stressed that there should be great growth potential for exporting products to domestic market. From the perspective of domestic consumption, the national epidemic prevention and control war has achieved significant strategic results, and the domestic market demand has been accelerated. From the perspective of investment, the promotion of new infrastructure, new urbanization and major projects in various places has brought new opportunities. From the perspective of consumption upgrading, some foreign trade enterprises are shifting from traditional mass production to personalized customization, and new consumption modes such as online sales and live delivery are developing rapidly, which has opened up sales channels for foreign trade enterprises directly facing consumer groups.

Li Danghui, deputy director of the Consumption Promotion Department of the Ministry of Commerce, said that the transfer of high-quality export products to domestic sales is not just a substitute relationship for the domestic market, but will further enrich the supply of the domestic market, increase consumers’ choices, accurately meet demand, and promote consumption upgrading.

It is understood that since the beginning of this year, China’s consumer market has been warming up month by month, the consumption of basic daily necessities has continued to grow, upgraded commodities have been more active, and the retail sales of housing and transportation commodities have been improved. This shows that under the normalization of epidemic prevention and control, the demand and pursuit of a better life of ordinary people are still growing, reflecting the great development potential and strong resilience of China’s consumer market.

At the same time, the Li Party will emphasize that the long-term common rules in the international market will also help to improve and enhance the domestic business environment, "which will help us fully release the advantages of super-large market scale and domestic demand potential, promote the formation of a large domestic cycle, and promote the mutual promotion of domestic and international double cycles".

In order to further relax the restrictions on domestic sales of processing trade enterprises, the "Implementation Opinions" proposed to further relax the time limit for domestic sales taxation, and adjust it from monthly declaration to quarterly declaration at the longest, which saved the cost of enterprises. Lin Shaobin, deputy director of the Enterprise Management and Inspection Department of the General Administration of Customs, said that this will greatly improve the overall efficiency of enterprises in handling domestic sales and play a positive role in exploring the domestic market. The data shows that in 2019, the domestic sales value of processing trade in China was about 338.3 billion yuan, up 8.4% year-on-year.

In addition, the Ministry of Commerce will hold a nationwide consumption promotion activity in the second half of this year, and use the advantages of pedestrian streets and key business districts in brand agglomeration, channel integration and market popularity to broaden the domestic sales channels of marketable export products. Help foreign trade enterprises to further connect with domestic large-scale commercial and trade circulation enterprises and e-commerce platform enterprises, and support all localities to include export-to-domestic products in the scope of consumption promotion activities.

　　[US stocks close]

　　Before the US stock market opened yesterday, the US non-agricultural report was released! The data shows that the number of non-agricultural employees increased by 209,000 in June, which was less than the expected increase of 230,000.

　　However, the average hourly wage in the United States in June increased by 4.4% year-on-year, higher than the expected 4.2%; The hourly wage increased by 0.4% from the previous month, which was also higher than the expected 0.3%; The unemployment rate dropped by 0.1 percentage point from the previous month to 3.6%, which was the same as expected.

　　After the non-agricultural report was released, the market thought that the possibility of the Fed raising interest rates by 25 basis points at the end of July was as high as 92%, which was roughly the same as before the non-agricultural announcement.

　　The faster-than-expected growth rate of hourly wages strengthened the Fed’s expectation of raising interest rates in July, and US stocks closed down across the board. At the close, the Dow Jones index fell 0.55%; The S&P 500 index fell by 0.29%; The Nasdaq index fell 0.13%.

　　The three major US stock indexes all recorded declines this week, with the S&P 500 index down 1.16%, Nasdaq down 0.92% and Dow down 1.96%.

　　Large technology stocks in the United States were mixed, with the semiconductor sector performing relatively strongly, while NVIDIA and TSMC both closed up. Among FAANMGT’s seven technology stocks, only Amazon closed red.

　　Popular Chinese stocks generally rose, with Nasdaq China Jinlong Index rising by 3.19%, Alibaba rising by 8%, Tencent ADR rising by 4.10%, and other Chinese stocks also floating across the board.

　　[futures closing]

　　The US dollar index fell sharply on Friday, boosting commodity prices. Metal futures generally rose, and silver rose by nearly 2%.

　　In terms of energy and chemical industry, only natural gas futures fell by nearly 2%, and the rest of the varieties were all red.

　　Agricultural futures are mixed. Cotton and sugar receive red; Soybean, corn and wheat, the three staple food varieties, closed down across the board.

　　In terms of financial futures, short-term US bonds closed up, while 10-year and long-term US bonds closed down.

　　[Economic data]

　　The United States’ non-agricultural production in June was less than expected, but the hourly wage growth rate exceeded expectations, which was difficult to stop the Fed from raising interest rates.

　　Under the continuous aggressive interest rate hike by the Federal Reserve, the signs of a slowdown in the US job market are gradually emerging.

　　According to data released by the Bureau of Labor Statistics last night, there were 209,000 new non-agricultural employees in June, the smallest increase since December 2020, which was lower than the market expectation of 240,000. At the same time, the number of non-agricultural new jobs in April and May was also revised downwards. The latest revised data shows that in the past six months, the average monthly employment increased by 278,000, far below the monthly average of 399,000 in 2022.

　　In June, new jobs in non-agricultural sectors mainly came from government, medical and health care, social assistance and construction.

　　However, it is worth noting that the average hourly wage in the United States in June increased by 4.4% year-on-year, higher than the expected 4.2%; The hourly wage increased by 0.4% from the previous month, which was also higher than the expected 0.3%; The unemployment rate dropped by 0.1 percentage point from the previous month to 3.6%, which was the same as expected.

　　What do analysts think?

　　Analysts generally believe that although the new employment slowed down in June, the unemployment rate is still at an extremely low level, the wage growth rate of workers exceeded expectations, and the Fed’s interest rate hike in July was almost "nailed".

　　"The labor market in the United States is slowing down, but the possibility of a sharp deterioration seems unlikely, and there are cracks in the job market. However, we believe that the risk of a sharp decline in the employment situation is low. Most leading indicators show that the current pace of employment growth is positive, but it is still far above the sustainable level." Aichi Amemiya, a senior American economist at Nomura, said, "As long as the overall employment remains high, the Fed may think that the risk of insufficient interest rate hikes is greater."

　　"Enterprises tried to correct the problem of over-recruitment during the epidemic by laying off employees, but by May this year, this trend seemed to be stable. The high-profile layoffs in the technology industry in the first half of this year did not point to broader signs of recession. In the past six months, we have not seen layoffs spread to other sectors of the economy. However, in view of the decrease in available funds, enterprises may continue to make personnel adjustments. " Layla O’Kane, a senior economist at Lightcast, a job market analysis agency, said.

　　"The slowdown in recruitment in June and the downward revision of employment in the past few months are not enough to reassure the Fed. Although the supply and demand of labor are tending to be balanced, the monthly increase of hourly wages and working hours has aggravated the inflation impulse. In view of the Fed’s concern about the inflation of’ super core services’, it is necessary to further raise interest rates to curb strong inflation. Bloomberg economists Stuart Paul and Eliza Winger analyzed.

　　Next week, the two major economies of China and the United States will release June CPI data. In addition, the second quarter earnings season of U.S. stocks will also kick off, with Pepsi firing the first shot and bank stocks following suit.

CCTV News:According to the Announcement of WeChat official account of the National Development and Reform Commission, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Commerce and the General Administration of Market Supervision (hereinafter referred to as the Announcement), it is emphasized that operators such as hotels and restaurants should comply with the same regulatory requirements as other operators such as Shangchao when processing, making and selling moon cakes.

　　In recent years, many hotels and restaurants have launched their own moon cake products during the Mid-Autumn Festival, providing consumers with more diversified and personalized choices and enriching the holiday market. However, a few high-end hotels and restaurants have become important channels for selling "sky-high" moon cakes. On the one hand, these enterprises use rare and precious ingredients, tie or mix high-priced goods, and over-luxury packaging, and create luxury goods in moon cakes with the help of brand advantages; On the other hand, the price of moon cakes is included in accommodation and meals to facilitate corruption.

　　According to the requirements of the Announcement, hotel and restaurant operators are not allowed to use wild protected animal ingredients as mooncake fillings, tie or mix mooncakes with other commodities, or violate the mandatory standards of over-packaging. At the same time, if mooncakes are required to be settled together with accommodation fees and meals, the unit price and quantity of mooncakes should be listed separately. Relevant departments will focus on high-end hotels and restaurants, and carry out all-round supervision and inspection. Once violations of laws and regulations are found, they will be severely punished according to law.

　　Mr. Yao spent more than 30 thousand yuan online to buy a computer and issued an invoice for the unit. Unexpectedly, after the arrival of the goods, he found that there was something wrong with the computer hardware, but when he communicated with the customer service staff, he was told that because it was a corporate invoice, he could not enjoy the package return service within 7 days, and he could only handle it after being tested by the technical department. After consulting Lenovo, Apple, Huawei and other parties, the Beijing Morning Post reporter found that Lenovo has the same regulations except Dell. Experts in the legal field pointed out that producers and sellers should not be exempted from the "three guarantees" obligation just because they are purchased by enterprises.

　　Company invoices can’t be "three guarantees"?

　　Mr. Yao told the Beijing Morning Post reporter that he placed an order in Dell official website on October 6th, spent 33,137 yuan to buy the latest products, and issued an enterprise invoice. Because the other party delayed delivery, he only received the computer on November 10th, and he opened it with great joy only to find that the computer had hardware problems. "The new machine is useless and there is a problem. I feel unreliable and I will return it to the after-sales. As a result, the other party said that because I opened a corporate invoice, I could not enjoy the related services of 7-day return and 15-day exchange. "

　　This made Mr. Yao very upset. Originally, he just asked for the issuance of corporate invoices. I didn’t expect this move to cause a lot of trouble. Yesterday, the Beijing Morning Post reporter dialed the telephone number of the staff responsible for Mr. Yao’s pre-sales. The other party said that he had reminded Mr. Yao when he made an invoice for shopping, but Mr. Yao insisted on issuing a corporate invoice. "We have relevant regulations, and only consumers who issue personal invoices can enjoy ‘ Three guarantees ’ Services cannot be enjoyed by opening corporate invoices. " The staff said that they have contacted the technical department at present, and hope that Mr. Yao will cooperate with the technical department to check, confirm the computer problems and help solve them.

　　At Dell’s official customer service office, the reporter got a similar reply. The other party said that because the enterprise invoice is issued, Mr. Yao can ask the technical department to come to the door for inspection through the after-sales process. "Generally, only maintenance and exchange are supported, and no return can be made."

　　Invoice treatment is not the same.

　　Can’t you enjoy the "three guarantees" service if you open an enterprise invoice for shopping? With questions, the reporter dialed the customer service telephone numbers of many enterprises in official website as consumers, but did not get a unified answer.

　　HP customer service staff said that no matter whether the invoice is issued by individuals or enterprises, as long as the machine system is not activated, you can enjoy the "three guarantees" service. "Whether it is a personal purchase or a corporate purchase has nothing to do with returning goods."

　　Huawei’s customer service also said that consumers can choose the nature of invoicing by themselves, and it will not affect the "three guarantees" policy and other after-sales services. "Whether it is a computer or a mobile phone, corporate purchases and personal purchases enjoy the same after-sales service." In addition, Apple, LeTV and other customer service also said that issuing corporate invoices does not affect consumers’ enjoyment of the "three guarantees" service.

　　However, Lenovo and other official customer service, like Dell, said that the "three guarantees" service is only for individual consumers and does not include enterprises. If consumers issue enterprise invoices, they will not enjoy the return service within 7 days.

　　Expert: Merchants should not shirk their responsibilities.

　　Chen Yinjiang, deputy secretary-general of China Consumer Protection Law Research Association, explained that strictly speaking, the Consumer Protection Law protects consumers’ behavior of buying, using goods or receiving services for their daily consumption needs. Consumers issue enterprise invoices after buying computers, and enterprises are business activities, not the needs of daily consumption, so their rights and interests are not protected by the Consumer Law. However, products purchased by enterprises are still protected by the Product Quality Law, the Contract Law and other relevant laws and regulations.

　　Chen Yinjiang said that according to the Product Quality Law, no matter whether the enterprise users or consumers buy goods, as long as they don’t have the proper performance, they don’t explain it in advance; Does not meet the product standards indicated on the product or its packaging; The seller shall be responsible for repairing, replacing and returning goods in case of any of the above situations, which are not in conformity with the quality conditions indicated in the product description and physical samples. If losses are caused to consumers who buy products, the seller shall also compensate for the losses.

　　In real life, many consumers will issue enterprise invoices or simply do not ask for invoices after purchasing goods or receiving services. "I personally think that as long as the buyer can prove that it is really for the needs of personal life, no matter whether it is invoiced or not, its rights and interests should be protected by the Consumer Law." In Chen Yinjiang’s view, businesses should not use this as an excuse to shirk their responsibilities and obligations. At the same time, he also reminded consumers to issue invoices as truthfully as possible when purchasing goods or receiving services.

　　Xinhua News Agency, United Nations, October 21st (Reporter Wang Jiangang) Geng Shuang, Deputy Permanent Representative of China to the United Nations, said on the 21st that China welcomed the unanimous adoption of Security Council resolution 2653 on sanctions against gangs in Haiti, and stressed that Haitian political factions should reach a consensus on the national political structure and transitional arrangements as soon as possible.

China hopes that resolution 2653 will send a clear signal to Haitian political factions, demanding that they immediately stop their ties with gangs, immediately stop their party struggles, put the interests of the country and the people first, and reach a consensus on the national political structure and transitional arrangements as soon as possible. China also hopes that resolution 2653 will send a clear signal to the Haitian people, indicating that the Security Council has been paying attention to their situation and will try to help them eradicate the scourge of gangs and remove the mountains that weigh on them.

　　Geng Shuang stressed that Haiti is on the verge of collapse and needs the help of the international community. The Security Council will continue to pay attention to the development of the situation in Haiti after the adoption of resolution 2653.
