Nowadays, there are more and more new energy sources. For many concerned car owners, how to carry out car maintenance, especially battery maintenance, has become a hot topic. Broadly speaking, charging is divided into three categories.

First, slow charging: almost all household charging piles belong to this category, because considering the overall voltage distribution of the community, it is generally controlled below 10w (Tesla is slightly higher). This method has relatively slow charging speed and takes a long time to fully charge the battery, but it has high charging efficiency and less loss on battery life.

The second is fast charging: the charging speed is very fast, and it usually takes about half an hour to fully charge the battery. However, the fast charging method has a great loss on battery life and needs to be used with caution.

Third, intelligent charging: intelligent charging is a charging method that can be automatically adjusted according to the battery state, charging voltage and charging current. This charging method can avoid the problems of overcharge and overdischarge to the greatest extent and protect the life of the battery.

The practice of stopping charging when charging to 80%-90% or the remaining 20% is mainly aimed at battery maintenance. In this case, keeping the battery in the range of 20%-80% is beneficial to the health of the battery. Because in this range, the state of charge (SOC) of the battery fluctuates little, which can effectively avoid deep discharge and full charge storage, thus delaying the aging speed of the battery.

For some new battery management systems, charging to 100% and discharging can give full play to the performance of batteries. The function of this management system includes actively balancing the battery charge to ensure that the SOC of each battery cell is consistent. In this way, the overall performance of the battery can be better played. For example, some electric bicycles feel that their battery life drops after being placed for a period of time, but after being used for a period of time, they feel that their battery life is back, which is the same reason. In the final analysis, new energy trams are electrical appliances, and for electrical appliances, they still need to be maintained frequently.

The correct charging method depends on your usage scenario and the function of the battery management system. If you pay attention to the life of the battery, it is a better choice to control the battery charge at 20% to 80%. But if you pursue the performance of the battery, charging to 100% and discharging it are more suitable for you.

At the same time, it is also very important to ensure that the charging environment of electric vehicles is dry, well ventilated and free of sundries, and to avoid charging in high temperature environment. Try to use original chargers, and avoid using poor quality chargers or non-original chargers. Inferior chargers or non-original chargers may have safety problems, which may lead to battery explosion and spontaneous combustion.

It is helpful to maintain the battery by deep discharge on a regular basis. In addition, frequent disassembly and assembly of the battery may lead to improper use of the battery and shorten its service life.

　　Xinhua News Agency, Washington, June 13 th, financial observation: Trade policy is "fiercer than tiger" and American enterprises are miserable and embarrassed

　　Xinhua News Agency reporter Xu Yuan

　　The destructive trade policy of the American government is becoming the biggest threat to the development of American enterprises. In recent days, from enterprises to trade associations, from large companies to small and medium-sized enterprises, business people have criticized the US government’s protectionist measures.

　　On behalf of 661 American enterprises and trade associations, the American lobbying organization "Tariffs Hurt the Hinterland of the United States" sent a letter to US President Trump on 13th, urging the US government not to impose tariffs on goods imported from China, and to return to the negotiating table to reach a solution with China.

　　The open letter warns that American enterprises and trade associations are worried about the situation of tariff escalation. The increase in tariffs and the uncertainty surrounding Sino-US trade negotiations have caused market turmoil and posed a threat to the US economy.

　　According to the survey released by the Business Roundtable composed of executives of large American enterprises on the 12th, the "Economic Outlook Index" fell by 5.7 points to 89.5 points in the second quarter. This index reflects the sales expectations, capital expenditures and recruitment plans of American business executives for the next six months, and shows that American business circles are increasingly uneasy about the direction of US trade policy.

　　"(The US government’s trade policy) is increasing the risk of bad economic results," said Jamie Dimon, CEO of JPMorgan Chase and chairman of the Business Roundtable at the press conference that day. "The uncertainty of trade policy, the weak global economic growth and the inaction of the US government on other urgent public policy issues are worrying."

　　Tom Linebarger, chairman and CEO of Cummins, an American engine manufacturer, said that "trade (policy) is the most terrible threat to enterprise growth". He said that imposing tariffs on China’s goods exported to the United States would increase consumers’ costs and reduce the competitiveness of American enterprises.

　　American financial data software company predicts that due to the uncertain tariff policy and global economic prospects, for those multinational companies whose sales are more than half from outside the United States, their profits in the second quarter may drop by 9.3%. The company expects that Apple’s profit may drop by 14.6% in the second quarter, and Boeing’s profit may drop by as much as 43.7%.

　　The U.S. government previously announced that the tariff rate on the $200 billion list goods imported from China will be increased from 10% to 25% from May 10, 2019. The U.S. government also threatened to impose a 25% tariff on the remaining about $300 billion of goods exported from China to the United States, involving many end consumer goods.

　　Lorraine Hutchinson, an analyst at Bank of America Merrill Lynch, predicts that tariff escalation will lead to growth risks for American retail enterprises such as clothing. According to the semi-annual survey recently released by institute for supply management, about 59% of American enterprises indicated that increasing tariffs would lead to higher product prices. Wal-Mart, an American retail giant, also said that tariffs will force it to raise the retail price of goods.

　　Tariffs not only hit large enterprises, but also make life more difficult for small enterprises. USA Today reported a few days ago that the negative impact of tariffs has exhausted the energy of many small American enterprises because their cost digestion ability is worse than that of large enterprises. Adjusting the supply chain will cost hundreds of thousands or even millions of dollars, which is unbearable for many small enterprises.

Vaccination is the most economical and effective measure to prevent and control infectious diseases.,To this end,Heilongjiang ProvinceProvincial CDCPublish 61 articlesCommon knowledge of vaccinationquestions and answers.

Data Map Source: vision china

　　1 Q: What is a vaccine?

　　A: It refers to the preventive biological products used for human immunization in order to prevent and control the occurrence and epidemic of diseases, including immunization planning vaccines and non-immunization planning vaccines.

　　Q: What is an EPI vaccine?

　　A: It refers to the vaccines that residents should be vaccinated according to government regulations, including those determined by the national immunization program, those added by the people’s governments of provinces, autonomous regions and municipalities directly under the Central Government when implementing the national immunization program, and those used by the people’s governments at or above the county level or their health authorities for emergency vaccination or mass vaccination.

　　Q: What is a non-EPI vaccine?

　　A: It refers to other vaccines voluntarily vaccinated by residents.

　　Q: What is a vaccine marketing license holder?

　　A: It refers to an enterprise that has obtained the registration certificate of vaccine drugs and the drug production license according to law.

　　Q: What is immunization program?

　　A: Immunization planning refers to the plans, plans and strategies formulated by using effective vaccines to vaccinate susceptible people according to the national infectious disease prevention and control plan, and to vaccinate people in a planned way according to the vaccine varieties, immunization procedures or vaccination programs determined by the state or provinces, autonomous regions and municipalities directly under the Central Government, so as to prevent and control the occurrence and prevalence of specific infectious diseases, and to improve people’s health level and health civilization level through the implementation of national immunization planning.

　　Q: What kind of immunization planning system does the country implement?

　　A: Residents living in China have the right to be vaccinated with EPI according to law and fulfill their obligations to be vaccinated with EPI. The government provides free immunization program vaccines to residents. The people’s governments at or above the county level and their relevant departments shall ensure that school-age children are vaccinated with immunization programs. The guardian shall ensure that school-age children are vaccinated with EPI vaccine on time according to law.

　　7 Q: What are the immunization program vaccines for school-age children in our province?

　　A: At present, the immunization programs for school-age children in our province include hepatitis B vaccine, BCG vaccine, inactivated polio vaccine, live attenuated polio vaccine, DTP vaccine, measles vaccine, live attenuated hepatitis A vaccine, live attenuated Japanese encephalitis vaccine, group A meningococcal polysaccharide vaccine and group A+C meningococcal polysaccharide vaccine.

　　Q: What is routine vaccination?

　　Answer: It refers to the vaccination service provided by the vaccination unit for the vaccinated object within a relatively fixed vaccination service cycle time in accordance with the national immunization program, vaccine use guidelines and vaccine use instructions.

　　Q: What is mass vaccination?

　　A: It refers to the organized and centralized vaccination activities for a specific group of people who may be threatened by an infectious disease within a specific scope and time. Supplementary immunization (formerly called "booster immunization") is a commonly used form of mass vaccination.

　　Q: What is emergency vaccination?

　　Answer: When the epidemic situation of infectious diseases begins or has an epidemic trend, vaccination activities are carried out for the target population in order to control the spread of infectious diseases.

　　Q: Why can vaccination prevent diseases?

　　A: Scientific research shows that when bacteria or viruses invade the human body, the body will produce a substance that resists the bacteria or viruses. This substance is called antibody. Different bacteria or viruses will produce different antibodies, which are called specific antibodies. After recovery, this specific antibody still remains in the body. If the corresponding bacteria or viruses invade the body again, this specific antibody can protect the body from these bacteria or viruses. Vaccination is to artificially inoculate a small amount of bacteria or viruses and their metabolites after being attenuated or inactivated, so that the body can produce specific antibodies or cellular immune responses, thus producing resistance against this pathogen.

　　Q: Why do you have to take vaccination according to the immunization program?

　　A: Different vaccines have different immunization procedures, which are based on clinical trials and years of scientific practice. Such as hepatitis B vaccine, pertussis-diphtheria-tetanus combined vaccine, polio vaccine, etc., at least three doses of vaccination are needed to make children have sufficient immunity. As children grow up, the immunity acquired by vaccination in the body will gradually decline. Therefore, some vaccines need to be strengthened.

　　Q: Can different vaccines be vaccinated at the same time?

　　A: Two or more injectable vaccines should be inoculated in different parts. It is forbidden to mix two or more vaccines and inhale them into the same syringe for inoculation. At present, all the vaccines in the national immunization program can be vaccinated at the same time according to the immunization procedure or the principle of replanting. Immunization planning vaccine and non-immunization planning vaccine can be vaccinated at the same time. If you choose not to vaccinate at the same time, priority should be given to ensuring immunization planning vaccine vaccination.

　　Q: How long does it take for different vaccines not to be vaccinated at the same time?

　　A: If two or more live attenuated vaccines for injection are not vaccinated at the same time, they should be vaccinated at an interval of ≥28 days. Inactivated vaccine and oral attenuated live vaccine, if they are not inoculated at the same time with other kinds of vaccines (including attenuated and inactivated), there is no restriction on the inoculation interval.

　　Q: How do migrant children get vaccinated?

　　A: In China, the vaccination of floating children is managed locally (that is, where they live), and floating children enjoy the same vaccination services as local children. If children under 6 years old move to other cities (regions) and counties (districts), they can directly carry the vaccination certificate issued by the health department of their original place of residence to the vaccination unit where they live now. If the vaccination certificate has not been handled before or is lost, the vaccination certificate can be reissued at the vaccination unit in the current residence.

　　Q: Which is better, imported vaccine or domestic vaccine?

　　A: Both domestic and imported vaccines have strict quality control systems to ensure the safety and effectiveness of vaccines. There is no obvious difference in performance between domestic vaccines and imported vaccines. No matter domestic or imported vaccines, all vaccines will have a certain level of adverse reactions, and there is no obvious difference in the level of adverse reactions between imported vaccines and domestic vaccines. Compared with domestic vaccines, imported vaccines have higher investment in R&D, and there is a certain gap between the prices of imported vaccines and domestic vaccines due to factors such as tariffs, freight and marketing costs. The choice of domestic vaccine or imported vaccine depends on the importance that individuals attach to the performance and price of the vaccine. If economic conditions permit, you can choose to vaccinate imported vaccines at your own expense, but if you consider the cost performance, it is also good to choose domestic vaccines. Don’t fall into the misunderstanding that the higher the price, the better.

　　Q: Why should BCG be vaccinated at birth?

　　Answer: After inoculation with BCG, the body can have specific immunity to Mycobacterium tuberculosis, which can prevent the reproduction and spread of Mycobacterium tuberculosis in the human body, so it has a good effect on preventing tuberculous meningitis and miliary tuberculosis. The World Health Organization suggests that newborns should be vaccinated with BCG as soon as possible in areas with high and moderate tuberculosis prevalence. China’s immunization program is to vaccinate newborns with one dose of BCG at birth.

　　Q: Why should newborns be vaccinated with hepatitis B vaccine within 24 hours after birth?

　　A: Most carriers of hepatitis B virus surface antigen in China come from vertical transmission from mother to child and early childhood infection. Because newborns have no immunity to hepatitis B virus and their immune function is not perfect, once they are infected with hepatitis B virus, they will easily become carriers of hepatitis B virus surface antigen. After infants less than one year old are infected with hepatitis B virus, more than 90% of them will become chronic hepatitis B virus surface antigen carriers. Thus, it is particularly important for newborns to prevent hepatitis B. All newborns should be vaccinated with the first dose of hepatitis B vaccine as soon as possible within 24 hours after birth, and complete the whole course of three doses of hepatitis B vaccine according to the immunization program of 0, 1 and 6 months old.

　　Q: Is it necessary to strengthen immunization after the whole vaccination of hepatitis B vaccine is completed?

　　A: At present, neither the World Health Organization nor China advocates the complete vaccination of hepatitis B vaccine and the booster immunization after successful immunization. This is because: after the successful initial immunization of hepatitis B vaccine, the immune persistence is good. According to domestic observation, the protection rate is still as high as 88.6% 15 years after vaccination. After natural exposure to hepatitis B virus (HBV), the memory B lymphocytes of successful immunization recipients inoculated with hepatitis B vaccine can rapidly proliferate, differentiate and produce specific antibodies after being attacked by HBV. It has been proved that humoral immune memory reaction still exists even among immunocompetents with low antibody or no antibody after 5 years. There is cellular immunity, and it has been observed that there is also specific cellular immune memory in addition to humoral immune memory response after vaccination with hepatitis B vaccine. Under the protection of hepatitis B vaccine, children can safely pass through the high-risk period of HBV infection (1 ~ 3 years old) without strengthening immunization, and with the function of immune barrier, the chances of infection of immunized children are greatly reduced. However, high-risk groups (such as hemodialysis patients, medical staff, etc.) should be tested for antibodies every 6 ~ 12 months, and when anti-HBS is less than 10 miu/ml, intensive vaccination can be carried out.

　　Q: How long will it take to have antibodies after hepatitis B vaccination? How long can it be protected?

　　A: Vaccination with hepatitis B vaccine is the most effective measure to prevent HBV infection. The effective component of hepatitis B vaccine is HBsAg, which induces human body to produce anti -HBs (hepatitis B surface antibody) and plays a role. After the first vaccination, most anti -HBs were still negative or below the lower limit of detection value; Anti -HBs turned positive about 1 week after the second injection, that is, it was immune to HBV 35-40 days after the start of inoculation; Inoculation with the third dose can significantly increase the level of anti -HBs and prolong the protection period. The positive conversion rate of anti -HBs is as high as 95%-100% after the whole vaccination of newborns, and the protection period can reach more than 22 years. After the human body actively produces anti -HBs, it has immune memory. Even if the anti -HBs turns negative and is exposed to HBV again, the body can produce anti -HBs in a short time. Therefore, it is not necessary for non-high-risk people to strengthen hepatitis B vaccination.

　　Q: What should adults do if they don’t produce antibodies after hepatitis B vaccination?

　　Answer: For those who fail to respond after three doses of hepatitis B vaccine, they can be vaccinated with one dose of 60μg or three doses of 20μg hepatitis B vaccine, and their serum anti -HBs will be detected 1-2 months after the second dose of hepatitis B vaccine. If there is still no response, they can be vaccinated with one dose of 60μg recombinant yeast hepatitis B vaccine.

　　Q: Can newborns of pregnant women infected with hepatitis B virus (HBV) breastfeed?

　　A: Although HBsAg and HBV DNA can be detected in the milk of pregnant women infected with hepatitis B virus, and some scholars believe that chapped nipples, excessive sucking of infants and even biting of nipples may transmit the virus to infants, these are theoretical analysis and lack of evidence-based medical evidence. Even without immunization, the infection rate of breast-fed and artificially fed newborns is almost the same. More evidence proves that even if pregnant women are HBeAg positive, breastfeeding does not increase the risk of infection. Therefore, after formal prevention, whether pregnant women are HBsAg positive or negative, their newborns can breastfeed, and there is no need to test whether there is HBV DNA in the milk.

　　Q: What should medical staff and others who accidentally expose hepatitis B virus do?

　　Answer: (1) Squeeze gently around the wound to discharge the blood in the wound, then rinse the wound with 0.9%NaCl solution, and then treat it with disinfectant. (2) HBV DNA and HBsAg should be detected immediately and rechecked after 3-6 months. (3) Those who have been vaccinated with hepatitis B vaccine and are known to be positive for anti -HBs (anti -HBs≥10mIU/ml) may not be treated. If you have not been vaccinated with hepatitis B vaccine, or if you have been vaccinated with hepatitis B vaccine, but the anti -HBs is less than 10 miu/ml or the anti-HBS is unknown, you should immediately inject 200-400 IU of HBIG, and at the same time, inoculate one dose of hepatitis B vaccine (20μg) in different parts, and then inoculate the second and third doses of hepatitis B vaccine (20μg) one month and six months later, respectively.

　　Q: Why should I stay on observation for at least 30 minutes after vaccination?

　　A: After vaccination, due to individual reasons, very few people may have allergic reactions. Monitoring data show that anaphylactic shock mostly occurs within 30 minutes after inoculation. After anaphylactic shock, if it is not under the supervision of medical staff, it is easy to be life-threatening. Therefore, doctors and first-aid drugs must be equipped at the inoculation site, mainly to prevent accidents. If the guardian suspects that his child has an adverse reaction to vaccination, he should consult or report to the vaccinator or the Center for Disease Control and Prevention in time.

　　Q: What is a suspected adverse reaction to vaccination?

　　A: It refers to the reaction or event that is suspected to be related to vaccination after vaccination.

　　Q: What are the classifications of suspected adverse reactions to vaccination?

　　A: It includes adverse reactions (general reactions and abnormal reactions), vaccine quality accidents, vaccination accidents, coupling diseases and psychogenic reactions.

　　Q: What are the conditions that do not belong to the abnormal reaction of vaccination?

　　A: The abnormal reaction of vaccination refers to the adverse drug reaction caused by the qualified vaccine in the process of implementing the standardized vaccination or after implementing the standardized vaccination, and the relevant parties have no fault.

　　The following situations do not belong to the abnormal reaction of vaccination:

　　(a) the general reaction after vaccination caused by the characteristics of the vaccine itself;

　　(2) Damage caused to the recipients due to vaccine quality problems;

　　(three) the damage caused to the recipients by the vaccination unit’s violation of the vaccination work norms, immunization procedures, guiding principles for vaccine use, and vaccination programs;

　　(four) the recipient is in the incubation period or precursor period of a disease at the time of inoculation, and the disease is coupled after inoculation;

　　(5) The recipient has vaccination contraindications specified in the vaccine instructions, and the recipient or his guardian failed to truthfully provide the health status and vaccination contraindications of the recipient before vaccination, and the original disease of the recipient has an acute recurrence or aggravation after vaccination;

　　(6) Psychogenic reactions of individuals or groups due to psychological factors.

　　Q: Why do some recipients have redness and inflammation in the injection area after vaccination?

　　A: Red swelling is a manifestation of inflammation and a common phenomenon in vaccination. It is the body’s responsive response to various damaging stimuli. It is characterized by local tissue deterioration, exudation and proliferation. When vaccinating, injection is often used, which itself can stimulate the human body to cause minor trauma and cause inflammation; At the same time, the vaccine itself is a foreign body and has certain toxicity. The pH, osmotic pressure and preservatives contained in the vaccine can cause inflammatory reactions to varying degrees. In addition, the inoculation of live vaccine is essentially a mild artificial infection, which can not only cause a mild infection process similar to the virulence of the microorganism, but also be accompanied by inflammatory reaction.

　　From the immunological point of view, inflammatory reaction is caused by the interaction between antigen and antibody or sensitized lymphocytes, which leads to the release of various inflammatory mediators by cells or the activation of inflammatory mediators in plasma or tissue fluid. Although the inflammation caused by vaccination may cause damage to the recipients, it is also conducive to the exudation of complement and antibody in the blood and strengthen the defense function.

　　Q: How to deal with the general reaction after vaccination?

　　A: After vaccination, you should stay in the vaccination unit for at least 30 minutes. Some children will have some reactions after vaccination, such as low fever, local redness and swelling, and may be accompanied by general discomfort, such as burnout, loss of appetite and fatigue. The above symptoms usually last for 1 ~ 2 days and disappear without any treatment. Children who have the above reactions after vaccination should take a proper rest, drink plenty of boiled water and keep warm to prevent other diseases from secondary. If there is a serious reaction, you should seek medical advice in time.

　　Q: Can children with neonatal jaundice be vaccinated?

　　A: Jaundice is a common clinical symptom in neonatal period, which can be divided into two types: physiological jaundice and pathological jaundice.

　　Physiological jaundice refers to the newborn’s 2 ~ 3 days after birth, which first appears on the face and neck, and then spreads all over the skin of trunk and limbs, with slight yellow staining and yellow sclera, but the palms and soles are not yellow, and the blood bilirubin is less than 12 mg/L, which reaches its peak on the 4 ~ 6 days after birth. Full-term infants mostly subside within 7 ~ 10 days after birth, and premature infants can delay to the 3 ~ 4 weeks. Children with physiological jaundice, except jaundice, are in good health, without other clinical symptoms, have normal urine and stool color, do not need treatment, have a good prognosis, and can be vaccinated with various vaccines.

　　Pathological jaundice can be divided into infectious jaundice and non-infectious jaundice (hemolytic disease of newborn, biliary atresia, breast-feeding jaundice, genetic diseases and drug-induced jaundice). If neonatal jaundice occurs in one of the following situations, it should be considered whether it is pathological jaundice: jaundice occurs within 24 hours; The degree of jaundice is deep and progresses rapidly, exceeding 6 mg/d L； in one day; Blood bilirubin > 12 mg/l; Jaundice lasts more than 2 weeks or reappears after it subsides. Pathological jaundice is the manifestation of the disease, and it should be treated in time, and vaccination is not allowed.

　　Q: Can allergic constitution be vaccinated?

　　A: The so-called "allergic constitution" is not a contraindication for vaccination. Allergic reactions are mild and severe, and serious allergic reactions caused by vaccines are rare. Compared with the risk of illness without vaccination, the benefit of vaccination is greater. The so-called "allergic constitution" can be observed after vaccination. If there are allergic manifestations, they can be treated in time, which generally will not affect health (nor affect the vaccination effect). If you are seriously allergic to the known vaccine ingredients or have laryngeal edema, anaphylactic shock and other serious systemic allergic reactions due to vaccination in the past, it is forbidden to continue to vaccinate the same vaccine.

　　Q: What common diseases are not taboo for vaccination at present?

　　A: Physiological and breast-feeding jaundice, history of simple febrile convulsion, stable epilepsy control, congenital inherited metabolic diseases (congenital hypothyroidism, phenylketonuria, trisomy 21 syndrome, etc.), stable brain diseases, congenital heart disease, congenital infection (syphilis, cytomegalovirus and rubella virus), etc.

　　Q: Is it necessary to vaccinate Covid-19 vaccine?

　　A: It is necessary. On the one hand, most people in our country have no immunity against Covid-19, and they are susceptible to Covid-19. After the onset of infection, some people will develop into critical illness and even cause death. After vaccination, on the one hand, most people can gain immunity, thus effectively reducing the risk of illness, severe illness and death; On the other hand, through the orderly vaccination of Covid-19 vaccine, we can gradually establish an immune barrier among the population, stop the epidemic of COVID-19, and restore the normal operation of China’s social economy and residents’ life as soon as possible.

　　Q: How does Covid-19 vaccine work in human body?

　　A: After vaccination, the human body will produce protective antibodies, and some vaccines will also make the human body have cellular immunity and form corresponding immune memory. In this way, the human body has immunity against diseases. Once Covid-19 invades the human body, antibodies produced by vaccines and cytokines released by cellular immunity can identify, neutralize or kill the virus, and immune memory can quickly mobilize the immune system to play a role, so that the virus cannot continue to proliferate in the body, thus achieving the purpose of preventing diseases.

　　Q: At present, how many kinds of Covid-19 vaccines have been approved for conditional marketing or emergency use in China?

　　A: Covid-19 vaccines from five manufacturers in China have been approved for conditional marketing or emergency use. Among them, there are 3 inactivated vaccines and 1 adenovirus vector vaccine approved for marketing conditionally; In addition, one recombinant Covid-19 vaccine (CHO cells) was approved for emergency use.

　　Q: Who are the approved vaccine manufacturers in Covid-19?

　　A: The three Covid-19 inactivated vaccine products that have been conditionally approved for marketing are produced by Sinopharm China Bio-Beijing Institute of Biological Products (Beijing Institute), Wuhan Institute of Biological Products (Wuhan Institute) and Beijing Kexing Zhongwei Biotechnology Co., Ltd. (Kexing Zhongwei).

　　The adenovirus vector vaccine approved for marketing conditionally is produced by Kangxinuo Bio-stock Company (Kangxinuo).

　　The recombinant subunit vaccine approved for emergency use is produced by Anhui Zhifeilong Kema Biopharmaceutical Co., Ltd. (Zhifeilong Kema).

　　Q: At this stage, who is the target of Covid-19 vaccine?

　　A: The vaccination target of Covid-19 vaccine in China is people aged 18 and above.

　　Q: At present, how many doses of Covid-19 vaccine are required to be used in China? How long is the interval?

　　A: At present, Covid-19 inactivated vaccine needs to be inoculated with two doses; The interval between the first dose and the second dose should be 3 weeks or more, and the second dose should be completed as soon as possible within 8 weeks after the first dose.

　　Adenovirus vector vaccine needs 1 dose.

　　The recombinant subunit vaccine needs 3 doses; The interval between the first dose and the second dose, and the interval between the second dose and the third dose are suggested to be 4 weeks or more. The second dose should be completed within 8 weeks after the first dose and the third dose should be completed within 6 months after the first dose.

　　Q: Where can I get the Covid-19 vaccine?

　　A: Vaccination in Covid-19 is carried out in vaccination units approved by local health administrative departments. Usually, the inoculation unit is located in the health service center, township health center or general hospital in the jurisdiction. If vaccination involves some departments or enterprises with relatively concentrated key targets, some temporary vaccination units will be set up locally according to the situation.

　　The health administrative department or disease prevention and control institution in the jurisdiction will also announce the vaccination units that can carry out Covid-19 vaccination as required, including the location and service hours. Please pay attention to the relevant information release platform.

　　Q: What are the contraindications for COVID-19 vaccination?

　　A: The taboo of vaccination refers to the situation that vaccination should not be given. According to the Technical Guide for Vaccination in Covid-19 (First Edition), the common taboos for vaccination include: 1. Those who are allergic to the active ingredients, any inactive ingredients and substances used in the production process, or those who have been allergic to similar vaccines before; 2. Those who have had severe allergic reactions to vaccines in the past (such as acute allergic reactions, angioneurotic edema, dyspnea, etc.); 3. People with uncontrolled epilepsy and other serious nervous system diseases (such as transverse myelitis, guillain-barre syndrome, demyelinating diseases, etc.); 4. Those who are suffering from fever, or acute diseases, or acute attacks of chronic diseases, or patients with uncontrolled serious chronic diseases; 5. Pregnant women. Some taboos, such as fever, are temporary. When the situation that caused the taboo no longer exists, you can vaccinate later.

　　Q: How to find and grasp the taboo of vaccination?

　　A: During the operation, if the first dose of vaccine causes severe allergic reaction, and it cannot be ruled out that it is caused by the vaccine, it is not recommended to vaccinate the second dose. To understand the ingredients of the vaccine, people who have been allergic to the ingredients of the vaccine in the past cannot be vaccinated.

　　At the time of vaccination, the recipient should truthfully report the physical health status, disease history and allergy history to the vaccination doctor; The vaccination doctor will ask about the health status and past allergy history of the recipient.

　　Q: Can Covid-19 vaccines from different manufacturers replace vaccination?

　　A: According to the Technical Guide for Vaccination in Covid-19 (First Edition), it is suggested to complete the whole vaccination with inactivated Covid-19 vaccine from the same company at this stage. In case of special circumstances, such as the vaccine can’t continue to be supplied, the recipients are inoculated in different places, and the whole process of vaccination can’t be completed with the inactivated vaccine of Covid-19 from the same enterprise, the inactivated vaccine produced by other enterprises can be used to complete the vaccination.

　　Q: Where and how to vaccinate Covid-19 vaccine?

　　A: At present, the five Covid-19 vaccines have been approved for inoculation in deltoid muscle of upper arm, and the inoculation route is intramuscular injection.

　　Q: What should we pay attention to in the process of vaccination in Covid-19?

　　A: During the vaccination process, the recipients should pay attention to and cooperate with the following matters:

　　Before vaccination, you should know about COVID-19’s disease, Covid-19’s vaccine and vaccination process in advance.

　　When vaccinating, you need to bring relevant certificates (ID card, passport, etc.), do personal protection according to local prevention and control requirements, cooperate with the on-site vaccination staff to ask, and truthfully provide information such as my health status and vaccination contraindications.

　　After inoculation, you need to stay for 30 minutes; Keep the skin of the inoculated area clean and avoid scratching the inoculated area with your hands; If there is any suspected adverse reaction, report it to the inoculation unit and seek medical treatment in time if necessary.

　　Q: Why do you have to stay on observation for half an hour after vaccination?

　　A: After vaccination, very few people may have acute allergic reactions and syncope. Acute allergic reactions that seriously endanger life safety often occur within 30 minutes after vaccination. In case of acute allergic reaction, you can take timely treatment measures at the scene. Syncope also occurs mostly within half an hour after inoculation. If you leave the observation site immediately after inoculation, you may cause accidental injury to the recipient due to syncope. Therefore, the recipients need to stay in the designated area of the vaccination unit for half an hour after vaccination.

　　Q: Why do you need a certain interval between doses of inactivated vaccine in Covid-19?

　　A: Usually, inactivated vaccines need to be vaccinated several times to achieve better immune effect. According to the clinical trial data, the first dose of inactivated vaccine in COVID-19 can stimulate the body to produce partial immune response, and the second dose can produce better immune effect. The interval between doses generally needs to be determined according to the results of clinical trials. If two doses of inoculation are not completed within the time required by the program interval, replanting should be done as soon as possible.

　　Q: How to replant those who have not completed the whole immunization program? Do you need to start over?

　　Answer: For vaccines with two or three doses of immunization, those who have not been vaccinated in the whole process are advised to replant the unfinished doses as soon as possible, and there is no need to restart vaccination according to the immunization program.

　　Q: Do people whose interval between two doses of inactivated Covid-19 vaccine is less than 3 weeks need replanting?

　　Answer: For those who have completed two doses of inactivated vaccine in Covid-19 within 14 days, one dose of inactivated vaccine should be replanted as soon as possible three weeks after the second dose. For those who complete 2 doses of inactivated Covid-19 vaccine in 14-21 days, there is no need to replant.

　　Q: Is it necessary to strengthen immunization after the whole vaccination of inactivated vaccine in Covid-19 at this stage?

　　A: Strengthening immunization is not recommended at this stage.

　　Q: It was suggested that HPV vaccine and Covid-19 vaccine should not be vaccinated at the same time. How long should the interval be?

　　A: Covid-19 vaccine is a new vaccine. In order to identify or distinguish possible suspected adverse reactions of vaccine, it is not recommended to vaccinate Covid-19 vaccine together with other vaccines (including HPV vaccine) at present. However, it doesn’t mean that you can’t vaccinate other vaccines after Covid-19 vaccination, but it is suggested that Covid-19 vaccine and other vaccines should be vaccinated more than two weeks apart. It must be noted that when rabies vaccine, tetanus vaccine and immunoglobulin need to be vaccinated urgently due to animal injury, trauma and other reasons, the vaccination interval with Covid-19 vaccine may not be considered.

　　Q: Can women of childbearing age and lactation be vaccinated with Covid-19 vaccine?

　　A: If you are pregnant after vaccination or have been vaccinated in the case of unknown pregnancy, based on the understanding of vaccine safety, it is not recommended to take special medical measures (such as termination of pregnancy) just because you have been vaccinated with Covid-19 vaccine. It is recommended to do a good job in pregnancy examination and follow-up. For women who have a pregnancy plan, it is not necessary to delay the pregnancy plan just because of Covid-19 vaccination.

　　Although there is no clinical research data on the effect of Covid-19 vaccine on lactating infants, based on the understanding of vaccine safety, it is suggested to vaccinate lactating women (such as medical staff) who are at high risk of Covid-19 infection. Considering the importance of breast-feeding for infants’ nutrition and health, and referring to the international practice, it is suggested that breast-feeding should be continued after breast-feeding women are vaccinated with Covid-19 vaccine.

　　Q: Can people aged 60 and above be vaccinated with Covid-19 vaccine?

　　A: People aged 60 and above are at high risk of severe illness and death after being infected with Covid-19. At present, the number of four phase III clinical trials of Covid-19 vaccine approved for marketing is limited, and the phase III trial of recombinant subunit vaccine is still in progress, and there is no data on the protective efficacy of the vaccine for this population. However, the data of the above-mentioned phase I/II clinical study of the vaccine show that the vaccination safety of this population is good. Compared with the population aged 18-59, the titer of neutralizing antibody after vaccination is slightly lower, but the positive conversion rate of neutralizing antibody is similar, suggesting that the vaccine will also have a certain protective effect on people over 60 years old, so vaccination is recommended.

　　Q: Can people with chronic diseases be vaccinated with Covid-19 vaccine?

　　A: People with chronic diseases are people with high risk of severe illness and death after being infected with Covid-19. People with chronic diseases with stable health and good drug control should not be considered as the taboo population for vaccination in Covid-19, so vaccination is recommended.

　　Q: Can people with impaired immune function be vaccinated with Covid-19 vaccine?

　　A: People with impaired immune function are people with high risk of severe illness and death after Covid-19 infection. At present, there is no data on the safety and effectiveness of Covid-19 vaccine for this population (such as malignant tumor, nephrotic syndrome, AIDS patients) and human immunodeficiency virus (HIV) infected people. The immune response and protective effect of this group of people may be reduced after vaccination. For inactivated vaccine and recombinant subunit vaccine, according to the safety characteristics of the same type of vaccine in the past, vaccination is recommended; For adenovirus vector vaccine, although the vector virus used is replication-deficient, there is no safety data of the same type of vaccine in the past. It is recommended to vaccinate after being fully informed that the benefits outweigh the risks.

　　Q: Do I need to get Covid-19 vaccine if I have been infected with Covid-19?

　　A: The existing research data show that it is rare to get reinfected in Covid-19 within 6 months after infection. Previous COVID-19 virus-infected people (patients or asymptomatic infected people) can receive one dose after 6 months on the basis of full notification.

　　Q: How long will it take to produce antibodies against Covid-19 after Covid-19 inactivated vaccine is inoculated?

　　A: According to the previous clinical trial of inactivated vaccine in Covid-19, the vaccinated population can have a good immune effect about two weeks after the second dose of inactivated vaccine is inoculated.

　　Q: Is it necessary to test antibodies before and after vaccination?

　　A: There is no need to carry out Covid-19 nucleic acid and antibody testing before vaccination; Routine antibody detection after vaccination is not recommended as the basis for successful immunization.

　　Q: Do I still need to do nucleic acid testing after Covid-19 vaccination? Can vaccination certificate replace nucleic acid test report?

　　Answer: After vaccination with Covid-19 vaccine, a very small number of the recipients still have positive nucleic acid test or illness due to protection failure: 1. After the whole vaccination, some people failed to get effective protection due to immune failure. After exposure to Covid-19, this group of people may be infected with Covid-19 and have positive nucleic acid test or illness. 2. It takes some time to produce protective effect after vaccination. If you are infected with Covid-19 during this period, you may detect nucleic acid positive or get sick. 3. Patients who are in the incubation period of the disease or asymptomatic infected people may still detect nucleic acid positive or get sick because they have been infected even after vaccination.

　　These people may become infected persons. When the prevention and control of epidemic situation in COVID-19 needs to be screened for nucleic acid, Covid-19 vaccination certificate cannot replace the nucleic acid test report, and it is necessary to cooperate with relevant departments to carry out nucleic acid test.

　　Q: After the mutation in Covid-19, is Covid-19 vaccine still effective?

　　A: According to the global monitoring of Covid-19 mutation, there is no evidence that virus mutation will invalidate the existing Covid-19 vaccine. Virus is one of the simplest organisms, and its proliferation depends on living cells. In the process of proliferation, the virus will mutate. The World Health Organization, research institutions in various countries, vaccine manufacturers, etc. are paying close attention to the mutation situation in Covid-19, and are also carrying out related research, which will provide early warning and scientific analysis basis for the follow-up vaccine development and application.

　　Q: What are the common adverse reactions of vaccination in Covid-19?

　　A: According to the results of the previous clinical trial of Covid-19 vaccine and the information collected during emergency use, the common adverse reactions of Covid-19 vaccine in China are basically similar to those of other vaccines that have been widely used. Common adverse reactions are mainly manifested as redness, induration and pain at the inoculation site, as well as clinical manifestations such as fever, fatigue, nausea, headache and muscle soreness. Relevant departments will continue to strengthen the real-time monitoring and evaluation of adverse reactions.

　　Q: Will our prevention and control measures be adjusted after vaccination in COVID-19?

　　A: For individuals, the protective effect of vaccination is not 100%, and it takes some time to produce protective antibodies. For the population, Covid-19 is still easy to spread without forming an immune barrier. Therefore, in order to prevent the COVID-19 epidemic from rebounding, some prevention and control measures should still be adhered to at this stage, including wearing masks, keeping social distance, washing hands frequently, ventilation and other protective measures. The prevention and control measures for COVID-19 epidemic will be adjusted in time with the improvement of vaccine coverage rate in COVID-19 and the change of epidemic situation at home and abroad.

　　Graduates enter the Chiudaba Gymnasium on a department-by-department basis, while Ernest & Young Rui is only one person. During his four years as an undergraduate, he has become accustomed to such a scene.

　　The college leaders plucked the ears for Ernest & Young Rui, and the end of this session meant that he had officially graduated from Peking University with a happy expression on his face.

　　While waiting in line to take graduation photos, students from the school joked with him: "For a graduation ceremony alone, you are popular, and this bouquet of flowers is for you."

　　He was preparing to leave the school around July 10, and was going to pack his things in the dormitory into cardboard boxes. Because he was about to stay on campus for graduate school, his luggage could also be stored in the dormitory during the holidays.

　　After the graduation ceremony, Ernest & Young Rui went to meet their graduate advisor and left a selfie while passing by Peking University Library. He said that in the next five years, it will be his most frequent place.

　　Holding up his phone, looking up, looking up, smiling, this summer, on the banks of Weiming Lake, under the Boya Tower, in front of the library, and at the entrance of Yuanpei College, Ernest & Young Rui, a paleontology major at Peking University, completed one "graduation photo after another" in a standard selfie pose.

　　Like his senior sister Xue Yifan, who graduated two years ago, these photos also made Ernest & Young angry. Four years ago, when he was admitted to Yanyuan with the top 20 results in Guizhou Province, he did not expect that the future experience would be so special.

　　During high school, this boy from Guiyang was interested in physics, biology, Chinese, and history. After the college entrance examination, it was difficult to choose a professional direction, so he chose Yuanpei College as an experimental field for thorough training.

　　In the first two years of college, like other students in the college, he took a large number of general education courses. After studying courses such as "Paleontology", his interest in this direction gradually became stronger, so he chose to major in paleontology in his junior year and became the "only seedling" of this major. Since Peking University established this direction in 2008, only six graduates have graduated in total, which is known as "six generations of single biography".

　　On June 9th, the crew of the film "Feng Shen Part I" appeared at the red carpet ceremony of the 25th Shanghai International Film Festival. Xinhua News Agency reporter Xin Mengchen photo

　　Xinhua News Agency, Beijing, August 28th (Reporter Leon, Zhang Manzi) As of 22: 00 on August 26th, the summer box office of China film market in 2023 exceeded 20 billion yuan, setting a new record for the summer box office. China’s summer box office jumped from nearly 17.8 billion yuan in 2019 to a new height of 20 billion yuan, injecting more confidence into the recovery of China and the global film industry.

　　China film industry is used to calling the three natural months from June to August every year as summer files. As the first summer file after China adjusted and optimized epidemic prevention and control measures, why did this summer file break the record? Analysts pointed out that cultural consumption, including movies, has gradually recovered. The types and themes of summer movies this year are diverse and rich, and popular works frequently appear, meeting the diverse needs of watching movies.

　　Yu Chao, deputy general manager of Capital Cinema, has the most outstanding feeling that "there are more outstanding films".

　　According to the data of the Lighthouse Professional Edition of the film data platform as of the morning of August 27th, the suspense film "She Disappeared" and the crime film "Put All Your Eggs on One Egg" ranked first and second in the summer box office list with 3.5 billion yuan and 3.3 billion yuan, followed by the mythical epic film "Goddess Part I" and the realistic film "The Octagon Cage", with box office of 2.4 billion yuan and 2.2 billion yuan respectively.

　　On April 21st, the cast members of "She Disappeared" were at the red carpet ceremony for the opening of the 13th Beijing International Film Festival. Xinhua News Agency reporter Chen Zhongyu photo

　　In the eyes of the industry, such a box office array is more healthy and stable than the box office champion of previous years, and the box office of the second or third place on the list has dropped to more than 1 billion yuan, showing that the overall quality of this summer’s movies is higher.

　　Chen Xuguang, director of Peking University Film and Television Drama Research Center, believes that the biggest feature of this year’s summer file is that the types and themes of films are more diverse, meeting the needs of audiences of different ages, "instead of simply focusing on student groups as before".

　　There are movies based on myths, legends and history, such as "The First Goddess" and "Three Wan Li in Chang ‘an", and there are movies with realistic themes, such as "Put all your eggs in one basket" and "In an octagonal cage", which play the role of "window" and let the audience better understand the society and protect themselves.

　　A good box office first stems from the excellent quality of the film. "China filmmakers pay more attention to ‘ Use money on the cutting edge ’ It also pays more attention to the quality of movies, and a number of domestic masterpieces have emerged. " Chen Xuguang said that there are a large number of movie audiences in China, and the types of movies should be as diverse as possible. "We are not afraid of no audience, but we are afraid that there are not enough good works.".

　　From June 21st to August 27th, the single-day box office of China film market broke through 100 million for 68 consecutive days, reaching a new high. Chen Jin, a data analyst of Lighthouse Professional Edition, pointed out that this sustained and stable box office performance has laid a sufficient foundation for the market to restore confidence, and the film industry has obvious signs of accelerating recovery. As of the afternoon of August 27th, the total number of screenings of this year’s summer file reached 33.7 million, setting a new record for the summer file.

　　The top six films in China’s summer box office this year are all domestic films, accounting for about 70% of the total box office. "Both the audience and the upstream and downstream of the industry have more confidence in the China film market after this summer file." Chen Jin said.

　　The Fifth Plenary Session of the 18th Central Committee of the Communist Party of China (CPC) was held in Beijing from October 26th to 29th, 2015, and General Secretary of the Supreme Leader made an important speech. The plenary session stressed that to achieve the development goals during the Thirteenth Five-Year Plan period, we must firmly establish and earnestly implement the development concept of innovation, coordination, green, openness and sharing.

　　This year is an important year for the implementation of the 13 th Five-Year Plan and the deepening of supply-side structural reform.

　　Whether the development goals of the "Thirteenth Five-Year Plan" can be achieved, there are 10 words that are crucial — — Five development concepts of "innovation, coordination, green, openness and sharing".

　　How important are the five development concepts for the current and future development of China? According to the Supreme Leader, the new development concept is baton and traffic light, which embodies the development ideas, development direction and development focus of China in the "Thirteenth Five-Year Plan" and even in a longer period.

　　Since the 18th National Congress of the Communist Party of China, the five development concepts have run through the economic and social development of China, and have really influenced our lives.

　　Advocating innovation: "China artifact" swipes the screen network, which has greatly improved my country.

　　In recent years, China’s economic growth has slowed down and its development has entered a "new normal", but some people think that China’s economy is dying! In response to this question, the attitude of the supreme leader is very clear. "I have firm confidence in the sustained and healthy development of China’s economy." At the same time, he also gave a "prescription" for the problems in development: the fundamental way out for China’s economic development to break through the bottleneck and solve deep-seated contradictions and problems lies in innovation.

　　How effective has this medicine been in the past five years? For ordinary people, the China artifacts that have been swiped on the Internet may have the deepest feelings: Beidou, the world’s most accurate navigation satellite system; Tiangong-2, the first real space laboratory; the world’s fastest supercomputer, Shenwei Light of Taihu Lake; Mozi, the world’s first quantum science experimental satellite; C919, a large domestic aircraft with international mainstream standards; and advanced world level. …

　　When we sigh "awesome, my country" again and again, we really feel the "welfare" brought by innovation and development. People in China who have these "artifacts" have a more convenient life, a more secure life and a harder waist abroad!

　　In the ranking of global innovation index published by the World Intellectual Property Organization in 2017, China rose from 35th in 2013 to 22nd, ranking first among middle-income economies.

　　Whether China’s economy will work or not, don’t fight a war of words, just prove it to you with tangible innovation achievements!

　　Pay attention to coordination: a well-off society in an all-round way is indispensable, and the promise to the people must be fulfilled.

　　In history, there are many examples of countries falling into a "trap" and stagnating because of unbalanced development. After China’s economic development has entered the "new normal", all kinds of speculations and worries about the "middle income trap" are rampant!

　　Undeniably, there are some unbalanced problems in the development of China, for example, in some places, "cities are like Europe, and rural areas are like Africa", and in some places, people are "pocketed and empty-headed" and so on. The proposal of coordinated development is an effective way to face up to and solve problems.

　　In the past five years, many achievements in the coordinated development of regions, urban and rural areas, economy and society can be personally experienced by ordinary people: the construction of rural teachers has been placed in a strategic position of giving priority to development, benefiting more than 3.3 million rural teachers and more than 40 million rural students; More than 31 provinces have introduced implementation plans for household registration system reform, and generally proposed to cancel the distinction between agricultural registered permanent residence and non-agricultural registered permanent residence and relax restrictions on settlement; The reimbursement rate of medical insurance for employees and residents is above 80% and 50% respectively … …

　　Coordinated development is not only to avoid falling into the trap, but also a solemn commitment made by the party to the people — — Build a well-off society in an all-round way by 2020. I believe that as long as we implement the concept of coordinated development and make up the weak areas, weak areas and weak links, an all-round well-off society will be realized as scheduled.

　　Advocating Green: "Lucid waters and lush mountains are invaluable assets" has become the consensus of the whole people.

　　While China has become the second largest economy in the world, the deteriorating ecological environment has also become the biggest "worry" for the people.

　　For economic growth, sacrifice the environment and ecology! For Jinshan Yinshan, I lost green mountains and green hills! This "GDP-only" development concept will never be agreed by ordinary people.

　　The supreme leader saw the crux of the problem and decisively put forward that "it is better to have green mountains and green hills than Jinshan Yinshan".

　　On the one hand, we will remove the curse from leading cadres at all levels. "Even if the GDP slips to the seventh and eighth places, it has made progress in green development and contributed to controlling air pollution and solving smog, then you can hang red flowers and be a hero."

　　On the other hand, the central environmental protection inspector has covered 23 provinces, put 1,183 cases on file for investigation, detained 1,103 people and held 11,390 people accountable.

　　Although, there is still a long way to go to solve environmental problems. But fortunately, after five years of hard work, the concept of "Lucid waters and lush mountains are invaluable assets" has become the consensus of the whole people. As long as China society continues to exert its strength from top to bottom, the "beautiful China" with clear sky and clear water will not be far away.

　　Thick planting and opening up: China has gained consensus and won respect in the international community

　　Nearly 40 years of reform and opening up, China’s social outlook, people’s living standards and international status … … Have undergone earth-shaking changes. And the occurrence of this series of changes, as the supreme leader said, "depends on unremitting efforts to promote reform and opening up."

　　How much does reform and opening up weigh in the hearts of the supreme leader? After taking office as general secretary, he left Beijing for his first inspection tour and came to Guangdong. At that time, he clearly pointed out that "reform will not stop and opening up will not stop". In the past five years, from the implementation of the FTZ strategy to the construction of the Belt and Road Initiative, from the G20 Hangzhou Summit to the upcoming meeting of BRICS leaders in Xiamen, from becoming one of the largest foreign investors in the world to China, which has contributed over 30% to the world economic growth annually and is already the "first engine of world economic growth", the pace of opening up has never stopped.

　　Adhering to the concept of open development has also enabled China to gain consensus and win respect in the international community. After the Belt and Road Initiative was launched, more than 100 countries (regions) and international organizations expressed their active support and participation, and 40 countries and international organizations signed cooperation agreements with China.

　　China’s opening to the outside world does not seek hegemony or expansion, but seeks win-win cooperation. At the same time of its rapid development, it has also provided development opportunities for all countries in the world and promoted world economic growth.

　　Promote sharing: strive to turn the "concern" of ordinary people into reality.

　　"Sense of gain" is a word that people are very concerned about now. The working class is concerned about whether the salary can be higher, the retirees are concerned about whether the pension can be higher, and the rural people are concerned about whether the income gap with the city people can be smaller … …

　　In fact, these are not only the concerns of ordinary people, but also the concerns of the CPC Central Committee.

　　In the past five years, the CPC Central Committee with the Supreme Leader as the core has never forgotten the solemn commitment of "making people have more sense of reform" and strived to turn the "care" of the people into reality: in 2016, the per capita disposable income of the national residents increased by 44.3% compared with 2012; Pensions have achieved "twelve consecutive rises"; The income gap between urban and rural residents has dropped to about 2.8 times; The rural poor population is decreasing by more than 10 million people every year … …

　　China’s economic development has achieved today’s achievements thanks to more than 1.3 billion people, and the fruits of development should be shared by more than 1.3 billion people. In the future, whether it is to build a well-off society in an all-round way or to realize the great rejuvenation of the nation, it is inseparable from the support of the concept of shared development.

　　In the past five years, China has solved many problems through development, but it still faces some problems. The five development concepts are put forward in view of the outstanding contradictions and problems in China’s development. Unswervingly implementing the five development concepts will surely lead China to approach the goal of national rejuvenation step by step and step by step to the center of the world stage.

China has 41,179 movie screens, ranking first in the world.

　　In 2016, the total box office of national movies was 45.712 billion, up 3.73% year-on-year. Compared with the growth rate of 48.7% last year, the good momentum has come to an abrupt end. In addition to the steady growth in the first quarter (Spring Festival file) last year, the box office was negative for five months in the next nine months.

　　Nearly 60% of the films made were not released.

　　In 2016, the number of cinema visitors in the city was 1.372 billion, an increase of 8.89% year-on-year. The growth rate of movie attendance is greater than that of box office, indicating that the average fare has decreased, and the national average fare is about 33.32 yuan.

　　In 2001, there were 84 films with box office exceeding 100 million yuan, including domestic movie 43 films. The box office of domestic films was 26.663 billion, accounting for 58.33% of the total box office, once again exceeding that of imported films. This year, many imported films are actually sponsored by domestic investors, such as Kung Fu Panda 3, Crouching Tiger, Hidden Dragon 2, or participated in the project, such as Warcraft, Bourne ultimatum 5, Star Trek 3, revenant, Hacksaw Ridge, Billy Lynn’s Long Halftime Walk and Nine Lives.

　　In the whole year, 772 feature films, 49 animated films, 67 science and education films, 32 documentary films and 24 special films were produced, totaling 944. Among them, less than 400 films have been shown in cinemas, accounting for 42%. In other words, nearly 60% of the films made have not been shown.

　　In 2016, there were 1,612 new cinemas and 9,552 new screens. At present, the total number of screens in China has reached 41,179 (more than 7,600 cinemas), surpassing the North American market (about 39,000) and becoming the country with the largest number of movie screens in the world. Last year, the number of screens in the world increased by 11,260, an increase of 8%, totaling 152,000. Among them, the number of screens in China increased by 8035, accounting for 71.36%. Judging from the changes in the past two years, the proportion of China’s screens in the world should be 21%-25%.

　　Hollywood blockbusters rely on China to attract gold.

　　In 2016, 724 movies were released in North America, with a box office of $11.25 billion, which was basically the same as last year. In fact, for many years, the mature North American market has maintained a stable state, and the number of people watching movies and the box office have not increased or decreased by more than 10%.

　　Therefore, overseas, especially China, has become a key market for major Hollywood film companies. Hollywood has been doing well, too. Many blockbusters have far more overseas box office than those in North America. For example, Captain America: Civil War, which has the highest box office in the world this year, has 64.6% overseas box office. For example, Kung Fu Panda 3 and Warcraft, the overseas box office accounts for 72.5% and 89.1% respectively. And a large part of these overseas box offices are sold in China. For example, the box office of Warcraft in China is as high as 1.472 billion RMB, which is equivalent to 212 million US dollars at the current exchange rate, accounting for 55% of the overseas box office of 386.3 million US dollars.

　　Because the China market is too big, the box office of a Mermaid in Stephen Chow is as high as 3.393 billion, ranking 12th in the global box office list in terms of US dollars. Compared with China, its North American box office is only $3.23 million, accounting for 0.6% of the global total box office. (According to Sohu)

　　What do you think of when you mention sinkholes? Mysterious, dark, strange and exotic animals and plants. The discovery of the Hanzhong Tiankeng Group in Shaanxi, China in recent two years has attracted the attention of the world. Tiankeng Group has become another beautiful business card in Hanzhong after the Han culture of "Two Han and Three Kingdoms".

　　The discovery of the sinkholes in Hanzhong increased the number of sinkholes in China from 84 to 138, accounting for 39%, and increased the number of sinkholes discovered and confirmed in the world from 117 to 171, accounting for 31.6%, making it a well-deserved "first sinkhole group in the world". Jean Bottazzi, an internationally renowned cave explorer, praised the Shanjiayan Cave River Tiankeng in Ningqiang, Hanzhong as "the most beautiful Tiankeng in the world".

　　On March 13th, the academic seminar of Tiankeng Group in Hanzhong, Shaanxi Province, hosted by Shaanxi Geological Survey Institute, was held in Xi ‘an. Famous experts, scholars and government officials from home and abroad discuss practical issues such as the future development mode, protection and development strategy of Hanzhong Tiankeng Group, and plan the blueprint for the future road of Hanzhong Tiankeng Group.

　　The other side of the beauty of Hanzhong in Tiankeng Group

　　When it comes to Hanzhong, the mysterious, beautiful and unknown sinkholes will show another side of Hanzhong. Let the ancient Hanzhong be more aura and beautiful than the rigid and serious history.

　　What is a sinkhole? Luo Gan Zhou, director of Shaanxi Geological Survey Center, gave his own answer to this question in a relatively easy-to-understand language. Tiankeng refers to a geomorphological feature that the steep walls around it have a certain scale (generally more than 100 meters in depth and width) and develop in carbonate rock areas.

　　"It is inferred that the sinkholes in Hanzhong Tiankeng Group were formed 180,000 to 120,000 years ago, and the oldest can be traced back to 680,000 years ago. By studying the sinkholes, we can study the ancient geographical environment and climate, which can help us better understand the past. Unique terrain and special ecological environment under negative terrain are the best places for people to understand geological and climate changes. " Luo Ganzhou expressed the significance of tiankeng to the contemporary era.

　　Li Yichao, a senior engineer of Shaanxi Geological Survey Institute who has been engaged in tiankeng investigation for a long time, went deep into the bottom of tiankeng for exploration and research many times. Speaking of the exploration of the Tiankeng Group in Hanzhong, Li Yichao has endless stories. Interest and hardship coexist, and the tiankeng, which is rare on weekdays, is really charming but full of challenges.

　　"Most of the traffic in tiankeng is not very convenient. After getting off the bus, the team members have to carry more than 100 kilograms of equipment and food to walk for five or six hours. Generally speaking, we may walk for two minutes at most at a distance of more than 300 meters, but it will take more than an hour to go down the sinkhole. It takes more time to get up, it takes more than three hours to get up, and you can only get up and down with the help of lifting and rescue equipment. The degree of hardship can be imagined. Professional climbing gloves, our team members can wear out three pairs a month. It can be seen that this is difficult. The investigation is very hard, but our contribution is worth it. " Li Yichao said.

　　Luo Gan Zhou Xiang told Uncle Fang a little detail: "Once I went down the sinkhole, the road was very steep. I walked downhill for several hours, and my toenails were against my shoes. When I got back, I felt that my toenails were very painful and the color was a little black. A few days later, the toenail cover of my big toe fell off directly, which was particularly painful." Luo Ganzhou, who is over 50 years old, speaks lightly, but the dangers and pains may only be known to him.

　　Of course, the hardships are also full of fun. The light in the sinkhole is insufficient, and the darkness is beyond imagination. When two people sit face to face, they don’t move, and you may not feel anyone around you. But in the sinkhole, you can see transparent fish, meet all kinds of strange animals and plants, strange stalactites, and all kinds of strange geological structures and climate phenomena that are hard to see on weekdays.

　　Through many photos taken by investigators, it is not difficult to find that there are many spacious cave halls, mysterious and strange underground rivers, magnificent stalactites, stalagmites, edge stone dams and many other ingenious works from nature. For thousands of years, a unique primitive microclimate has been formed in the sinkhole, and the animal food chain and unique habitat in it are irreplaceable. In addition to these peculiar geological products, there are many animals and creatures, among which thousands of richness such as "Shafei Colored Grey Butterfly", "Blooming Pink Butterfly", "Elephant Cicada", "Green Scarab" and "Liliaceae Big Lily" were photographed by the respondents alone.

　　Flying cats are unique animals in Hanzhong Tiankeng. The flying cat’s scientific name is the flying squirrel, also known as "six unlike". It has a face like a fox, eyes like a cat, a rat with a pointed mouth, ears like a rabbit, paws like a duck, and a tail like a squirrel. Its wide fins between the front and rear legs can glide between cliffs and trees, with a maximum head and tail length of 1 meter and a weight of more than 7 kg. This kind of animal is very shy. It lies in the daytime and comes out at night. In addition, it is increasingly rare. It is not easy to see a living flying cat with one’s own eyes.

　　It is understood that the Hanzhong Tiankeng Group is the first tiankeng group with the highest latitude in the world discovered in the range of 32 ~ 33 north latitude. This discovery has important scientific value and fills the gap in the world karst geology research. There are 54 Tiankeng Groups in Hanzhong discovered this time, which are mainly distributed in Chanjiayan Town, ningqiang county, Hanzhong City, Xiaonanhai Town, Nanzheng County, Luojiaba Town, Xixiang County and Sanyuan Town, zhenba county. This discovery has increased the number of sinkholes in the world from 117 to 171, accounting for 1/3 of the global number of sinkholes, including 2 super sinkholes, 7 large sinkholes, 45 conventional sinkholes and 473 other geological relics.

　　Academician Yuan Daoxian of Chinese Academy of Sciences believes that the Hanzhong Tiankeng Group is located at latitude 32-mdash; — It was discovered for the first time in the range of 33 degrees, which made China moist in the tropics — The boundary of subtropical karst landform area has obviously moved northward, which has important scientific value. Reasonable protection, development and utilization of geological relics resources of Tiankeng Group will play an important role in promoting local economic development.

　　The important value of the discovery of the rare "Tiankeng Group" in Hanzhong lies in that it not only greatly enriches the tourism resources of geological relics in China and even the world, but also fills the blank of karst geology research in the world and increases the original samples of biological research. Through the study of its formation mechanism, conditions and evolution law, it will be of great scientific value to the study of paleogeographic environment and climate change in the north and south of China and even the whole world, and it will be praised by experts as a world-class "natural museum" that rewrites geological history.

　　Ambition to declare world geoparks and natural heritage

　　The geological park selected by UNESCO is a natural park with its geological scientific significance, exotic beauty and unique geological landscape, which integrates natural landscape and human landscape. The goal of UNESCO is to select more than 500 geological landscapes worthy of preservation and strengthen protection. At present, 35 geoparks in China have entered the UNESCO World Geopark Network List.

　　Whether it is a geopark or a world natural heritage, it is a leader in the global natural landscape, and its scientific significance and tourism appreciation significance are self-evident.

　　The reporter learned from different channels that at present, all parties are actively preparing for the world geopark and natural heritage declaration for the unique geological relic of Hanzhong Tiankeng Group.

　　The Hanzhong Municipal Government specially issued the Interim Measures for the Protection and Management of Geological Relics of Tiankeng Group in Hanzhong City, which made specific provisions on the scope of geological relics protection, regional management and protection measures, and legal responsibilities. Hanzhong will conscientiously do a good job in the protection of geological relics of Tiankeng Group in Hanzhong.

　　Hanzhong Municipal Bureau of Land and Resources said in a reply that Hanzhong will gradually promote the declaration of national and even world geoparks and natural heritage in due course.

　　It is understood that in October 2016, the Shaanxi Provincial Department of Land and Resources has awarded the provincial geological park construction qualification of Hanzhong Tiankeng Group; According to the provincial geological park planning to complete the construction task, Shaanxi Provincial Department of Land and Resources acceptance before the provincial geological park can be named. Provincial geoparks can only be declared as national geoparks after they are officially named for two years. Hanzhong will do a good job in basic work and declare national and even world-class geological parks and natural heritage according to relevant procedures.

　　Mao Xiaochang, a senior engineer of China Geological Survey, said in his speech that the formation mechanism of Hanzhong Tiankeng Group is different from that of South Tiankeng Group, and its biodiversity is also unique. Therefore, Hanzhong Tiankeng Group has the conditions to become a world-class in terms of rarity, scientificity, aesthetics and protection.

　　How to make good use of high-quality resources in developing and protecting economically underdeveloped areas

　　Tiankeng is a unique natural wonder, unique to karst conditions. In the natural landscape, it has a series of special tourism ornamental values and sensory attributes, such as rarity, strangeness, precipitousness, grandeur, beauty and unique ecological environment. At the same time, tiankeng always coexists with caves, underground rivers, strange peaks and rocks and other tourism resources, so it is undoubtedly a special super tourism resource.

　　It is understood that Chongqing Xiaozhai Tiankeng was opened to tourists in 1999, and Guangxi Leye Dashiwei Tiankeng Group is in the process of tourism development planning. In the future, the karst tiankeng scenic spot will add a bright spot to the world tourism industry.

　　How can Hanzhong miss such a good opportunity? In May, 2017, Hanzhong Municipal Bureau of Land and Resources and Hanzhong Municipal Bureau of Cultural Relics and Tourism jointly reported the topic to Hanzhong Municipal Government, suggesting that the world-class planning units should be selected, and in accordance with the principle of "development in protection and protection in development", Hanzhong Tiankeng Group’s geological relics protection and tourism development and utilization plan should be actively worked out, combining Tiankeng tourism with new formats such as culture, leisure, recreation, sports and research, and steadily promoting the geological relics protection and tourism development of Hanzhong Tiankeng Group.

　　Faced with such world-class tourism resources, it is reasonable for Hanzhong, which is economically underdeveloped, to have the impulse to develop and utilize it. However, tiankeng resources belong to non-renewable natural heritage resources, and once improperly developed, it will bring irreparable losses.

　　At the seminar, the reporter also heard different voices, but the voice of "protection first and moderate development" still dominated. For Hanzhong, where the economic strength is not strong and the pressure of getting rid of poverty is great, how to use the resources of Tiankeng Group to promote regional economic development and promote the local people to get rich and increase their income has become the main problem faced by the politicians.

　　The reporter had a detailed exchange with the deputy county (district) governors of zhenba county, Nanzheng District and ningqiang county. The conclusion is that everyone wants to use Tiankeng resources to promote the development of county economy, but this kind of utilization must be based on strict protection, and we should avoid rough development and homogeneous development of four counties, and start with high-end tourism and take a sustainable development path.

　　Zhou Qingfu, deputy county magistrate of zhenba county, told reporters that zhenba county will make rational use of Tiankeng, a high-quality resource, publicize Zhenba’s good ecological environment advantages on the basis of strict protection and reasonable planning, develop the Chinese herbal medicine industry around the high-quality ecological environment, and build Zhenba into a high-quality health care, pension, sports and experience base.

　　Wang Jun, the deputy head of Nanzheng District, also put forward his own views on the development of Hanzhong Tiankeng Group. Hanzhong Tiankeng Group should avoid large-scale development and give priority to protection. At present, it is difficult to develop Tiankeng with the ability of counties and districts, and it is easy to cause homogenization. Tiankeng is ecologically fragile and unrecoverable, and its safety is poor, so the development of Tiankeng should take the road of high-quality development.

　　Wang Longqing, chairman of Hanzhong CPPCC, believes that Tiankeng Group is the most precious, valuable and internationally influential resource discovered in Hanzhong so far. Establishing a research base for Tiankeng Group in Hanzhong is beneficial to the investigation, scientific management and development, geological monitoring and protection of Tiankeng Group in Hanzhong. Hanzhong City should take this opportunity, rely on the scientific research base as the platform, fully support the geological exploration work of the Provincial Geological Survey Institute, make overall consideration of the construction of the research base and geological museum, as well as security measures, attract world-class high-level talents to come to China for extensive exchanges, hire international professional teams to carry out development planning, and promote the scientific research and tourism development and utilization of Hanzhong Tiankeng resources in an orderly manner.

　　Mao Xiaochang, a senior engineer of China Geological Survey, also put forward his own views on the development of tiankeng. First, priority should be given to protection, and a high-end tiankeng adventure tour can be explored under the premise of protection. Tiankeng, a tourist resource, is not suitable for large-scale development. The location of the sinkhole should explore the mode of high-end in-depth tour, and professionals can be explored to explain professional geological and geographical knowledge to tourists, so that tourists can fully feel the unique charm of the sinkhole through five or six hours of in-depth tour. In addition, we can try to involve villagers in tourism, and develop some special projects such as geological and cultural villages and towns in the periphery to promote the development of local people.

　　Facing high-quality natural resources development and protection are not contradictory opposites. If we cling to the principle of protection and don’t make rational use of it, it will only be a good opportunity to delay development. If Jiuzhaigou clung to protection and didn’t seek development, it would be difficult to achieve such great achievements in local economic development today. However, development is not a kind of quick success and instant benefit, and it is a rational development path for the protection and local development of Tiankeng Group in Hanzhong to make long-term planning and rational utilization from the perspective of future generations’ long-term development. Presenting the most beautiful side of Hanzhong to the world may be the best protection for Hanzhong Tiankeng Group.

Recently, one of Qian Aunt’s franchisees, the "Third Sister", broke the news on the Internet, saying that she had been losing money since she joined two Qian Aunt’s houses with an investment of 1.7 million yuan, and she was forced to close the store out of stock, so she had no choice but to speak online to defend her rights and accuse Qian Aunt of unreasonable joining policies and management problems, which caused widespread concern.

△ The Tik Tok account of "Silly Third Sister" is now "no such person"

In fact, this franchisee’s experience is not a case. On Baidu Post Bar, Tik Tok and other platforms, there are a lot of franchisees’ information about Aunt Qian.

Some people say that the store has been losing money since joining Qian Aunt, and the investment has reached 800,000 yuan. There are also franchisees who broke the news that they joined Qian Aunt, and they lost more than 200,000 yuan in two months of opening. Together with the previous investment, the overall loss has exceeded 700,000 yuan. At present, the store is in the process of transfer.

On platforms such as 58 City, you can also see a lot of transfer information about Aunt Qian. Some franchisees said that there were few transfers before last year, and some were internal transfers, but this situation has changed this year.

What happened to Qian Aunt, a star company that was robbed by capital and is expected to be listed on Hong Kong stocks this year?

Before answering this question, let’s take a look at how it started.

one

How did Aunt Qian get started?

Nine years ago, the founder of Qian Aunt opened a pork shop in a vegetable market in Dongguan. Because it advertised "No overnight meat", it affected other people’s business and was driven out of the vegetable market.

When Aunt Qian got off to a bad start in Dongguan, she moved to Shenzhen. In 2013, the first Qian Aunt in Shenzhen opened in Futian, and the slogan "Don’t sell overnight meat" quickly attracted the attention of local people. Since then, Aunt Qian has quickly opened more than 1,500 stores in Guangdong.

The rapid development of Aunt Qian has naturally attracted the attention of capital. During 2015-2019, Aunt Qian received five rounds of investment, including many star investment institutions. The latest financing took place in December last year, when Aunt Qian’s valuation reached 8.5 billion to 10 billion yuan.

△ Figure from the network

Driven by capital, Aunt Qian started a journey of crazy expansion. In November 2020, Aunt Qian entered Zhengzhou; In December 2020, he entered Beijing; In January 2021, she entered Tianjin, Fuzhou and other places: Aunt Qian is gradually moving from the region to the whole country.

According to official data, from July 2020 to February 2021, in seven months, the number of Qian Aunt’s stores expanded from 2,000 to 3,000, with an average of 142 stores opened every month.

Of course, the rapid expansion of Aunt Qian mainly depends on franchisees, and the proportion of its franchisees is close to 90%. Under the joining mode, Aunt Qian only needs to build a good supply chain, build a good model store and do a good job in attracting investment, so she can open a store quickly.

So, how much does it cost to join a money aunt?

2

How much does it cost to join Aunt Qian?

First of all, before opening a store, you need to pay the initial fee, deposit, decoration fee and so on. Each store has an initial fee of 30,000 yuan and a deposit of 40,000 yuan; The decoration fee is 200,000 to 300,000 yuan-some franchisees questioned that Aunt Qian’s decoration fee is too high, far exceeding the market price, which means that she wants to earn the franchisee’s money through the decoration fee.

Secondly, in order to ensure the passenger flow, Aunt Qian generally requires franchisees to find stores in prime locations, and the transfer fee of such stores is often as high as 100,000 yuan. Calculated, if a franchise store wants to open, the above expenses alone will reach 500,000 yuan.

Besides, to recruit a store manager, a division division and a shop assistant, franchisees need to pay Qian Dama a "service delivery fee" ranging from 6,000 yuan to 4,000 yuan and 800 yuan, and the wages of these people are calculated separately.

In this way, if you want to open a money aunt, you must have at least 550,000 yuan, which is obviously not a small number.

So, do you think you can make money by opening a business? Not really! And on the contrary, opening a business means paying more money!

Why did Qian Aunt’s franchisees lose blood?

After the store is opened, there will be a continuous brand use fee. For the income generated by franchisees before 19:00 every day, Aunt Qian should draw 1.5% of the turnover as the brand use fee.

For newly joined stores, three months before the opening of the store is the drainage stage, and Aunt Qian requires that the goods cannot be increased in price, but can only be "flat in and flat out". After the drainage, the price can only be raised after the sales amount reaches the standard set by the company, and the price increase is also strict.

Therefore, the phenomenon that money aunt is in the market is basically what franchisees throw out with real money every day. Moreover, such regulations have also caused a phenomenon: the more franchisees order after opening, the higher the cost, the more losses, and the faster franchisees may "die".

After the price can be raised, franchisees will face a very realistic problem: many people who buy meat and vegetables are aunts and grandmothers, who are very sensitive to the price. After the price is raised, they would rather go a little further to buy cheaper ones, resulting in a decrease in the passenger flow of Qian Aunt’s store, which in turn reduces the income.

In addition, franchisees will also face increasing "involution".

There have been media reports that at the end of 2017, Aunt Qian has shortened the minimum distance of the store from 300 meters to 250 meters. In this way, the store density of Aunt Qian has increased, and the brand has started, but the regional protection has also weakened, the competition of franchisees has also intensified, and the profitability has naturally declined.

According to Qian Aunt’s franchisee, in the past, Qian Aunt asked for at least 1,500 households to choose a community, but now many communities can open stores as long as four or five hundred households. This kind of traffic simply cannot support the normal operation of a store. What’s more exaggerated is that two money aunts have been opened in many communities, and the internal competition is fierce, which has aroused the dissatisfaction of franchisees.

According to analysis, the reason why Aunt Qian wants to open stores intensively (for example, in Guangdong, the base camp, there are nearly 1,000 stores in Shenzhen and Guangzhou alone) is because of financial pressure to rush to the market; The more stores it opens, the more it earns under the condition of ensuring a certain net interest rate, but it just passes on the costs and sacrifices to franchisees.

Therefore, for Qian Aunt’s franchisees, the investment of 550,000 yuan to open a store is only the beginning, and the continuous loss is the normal state of many franchisees.

Franchisees are dissatisfied with Aunt Qian and these six points.

According to the Dining Book, in addition to the above, franchisees are mainly dissatisfied with Aunt Qian in the following aspects:

First, there are too many "must-haves". Aunt Qian has certain products in every store. These "certain products" are unified in the whole region, but the problem is that there are a large number of "certain products", and some "certain products" are not hot-selling goods. Many stores simply can’t sell them out, and the products that can’t be sold out will be discounted, which will eventually cause losses for the stores. Take beef as an example. Some franchisees said that Aunt Qian’s beef is not a hot commodity, and his daily loss in beef is as high as that in 200 yuan.

Aunt Qian has requirements for suppliers and the amount of goods they buy every day, and they can’t be returned after 12 noon. In this case, if you are not sure about the purchase quantity, it will easily lead to inventory, and the inventory will be discounted, and a discount will consume profits.

Second, the purchase price is too high. It is understood that Qian Aunt earns the most money from pork, but its pork price is about 20% higher than the normal price of foreign mining. In addition, Qian Aunt’s dishes in many places are purchased from nearby vegetable markets and then sold to franchisees at a higher price, which makes many franchisees unbearable.

Third, the fine is unreasonable. First, according to the regulations, franchisees can only purchase goods from headquarters. Once they are found to purchase goods from outside, they will be fined 20,000 yuan. Second, Aunt Qian has strict regulations on the goods that can’t be sold out, and she can’t sell them overnight, not even eggs. The franchisee "Sanjie" at the beginning of the article, her employee was fined once for selling eggs overnight.

Interestingly, after the "Three Sisters" exposed Qian Aunt on the Internet, Qian Aunt’s South China area adjusted the fine amount the next day, and the fine amount directly dropped from 20,000 to 10,000 yuan.

Fourth, increase the amount privately. According to the franchisees, many stores of Aunt Qian have been "privately added", and no matter whether the store wants it or not, it will be added to the store privately. During the Dragon Boat Festival, many stores suffered great losses because of selling zongzi. Some stores bought two zongzi, but when they received the goods, they received more than 20 pieces, which could not be sold at all.

Fifth, order less. It is understood that the daily order quantity of the store is between 300 and 400 pieces. After being delivered to the store, the franchisee can’t check them one by one at the first time, which will cause losses. For example, four watermelons were ordered, but only three were actually delivered. This kind of scene is more common, and it also gives many franchisees a headache.

Sixth, internal corruption. According to a franchisee in Shenzhen, Qian Aunt’s shop was recommended by the company, and the price was also negotiated by the company. Finally, the rental price for the franchisee was 28,400 yuan/month, and later the franchisee directly negotiated with the landlord for 20,000 yuan/month (the price to be transferred). Because the rent of the store was raised, Aunt Qian’s development department also charged a "tea fee" of 14,000 yuan, and the franchisee had to pay the company a "site selection fee". The practice of "eating at both ends" in the development department makes franchisees very speechless.

There is not much time left for aunt Qian.

In the final analysis, the reason why franchisees don’t make money is due to the blind expansion of Aunt Qian. Its supply chain in many places is not perfect, and the cost for franchisees is too high.

Guangdong is Qian Aunt’s base camp, and there are enough stores here to form a scale effect, so that Qian Aunt has bargaining power on the upstream, which can reduce costs and leave profit space for franchisees. But in other places, this model has encountered challenges.

Aunt Qian’s crazy expansion in the country seems to be a lot, but on average, in every city, the number is not much. In this case, the bargaining power is limited when purchasing from local suppliers, and the cost cannot be suppressed. The cost can’t be suppressed, but to ensure its own profit space, it can only be passed on to franchisees.

Of course, in the base camp of Guangdong, Aunt Qian is not completely "safe". According to franchisees, many stores in Guangzhou and Shenzhen have closed this year. In the 58 cities of Guangzhou and Shenzhen, you can also see a lot of information about the transfer of Aunt Qian-the crazy expansion of Aunt Qian has begun to have an impact on her base camp.

Aunt Qian made money and gained the reputation of consumers, but many franchisees suffered miserably. This is a model that violates the basic laws of business. This irrational, inconsistent interests and unable to achieve a win-win model is doomed to be unsustainable.

All the rapid expansion is based on the premise of profit. If Aunt Qian expands crazily for listing, but regardless of whether the franchisees are profitable, there will be big problems. This kind of expansion is "stepping on the body of the franchisee", so even if it can finally go public, it is also a bloody listing.

It is reported that at present, there are franchisees who are preparing to go through legal procedures and file a lawsuit with Aunt Qian.

The time left for aunt Qian may really be running out.
