Since the second half of 2023, Meituan and JD.COM Platform have carried out rapid home nucleic acid detection in some cities. At present, the testing items are as follows:

There are always parents who ask me: Is the quick test of nucleic acid at home accurate or not?

In fact, doctors and colleagues and I often discuss this issue. Our feeling is that sometimes it is accurate and sometimes it is not.

Through nearly half a year’s contact, we found that the rapid detection of nucleic acid at home is helpful to analyze the cause of upper respiratory tract infection in the community. In particular, the newly added pertussis test is convenient for early investigation and is really useful.

However, the detection rate of individual pathogens is doubtful, and some testing items seem unnecessary.

Here are two valuable cases. These two children not only did a quick home nucleic acid test, but also measured a very accurate tNGS (targeting high-throughput sequencing), which can be compared and analyzed.

As always, thank parents for their consent before sharing.

01

Case 1

A 7-year-old child saw a doctor at 12 noon on June 21st. The medical history is as follows:

When I saw a doctor, I had been coughing for 5 days. Because his deskmate was recently diagnosed with whooping cough, according to the clinical diagnosis standard B of CDC in the United States, if other diseases are excluded, whooping cough can be clinically diagnosed without laboratory tests.

Considering the 14-day course of antibiotic treatment and whether the family members take post-exposure prevention, after discussion with parents, it was decided that the presence of pertussis should be determined by rapid examination in JD.COM, and the drug-resistant pertussis infection should be evaluated by targeted sequencing. The specific plan is as follows:

At 15: 16 (more than 2 hours after sampling), the quick test results show that:

At noon on June 22nd (the second day after seeing a doctor), targeted sequencing showed that:

Through this case, we can draw the following conclusions:

1. The Bordetella pertussis detected this time is accurate (confirmed by sequencing).

2. The Streptococcus pneumoniae strain detected this time is false positive (negated by sequencing).

Why is there a false positive?

It is speculated that the primer design for rapid detection of Streptococcus pneumoniae in laboratory has defects and insufficient specificity, and Streptococcus angina with similar nucleic acid sequence is mistaken for Streptococcus pneumoniae.

3. The Haemophilus influenzae detected this time is accurate (confirmed by sequencing).

4. Targeted sequencing can identify whether there is drug resistance gene mutation in Bordetella pertussis, which is convenient for drug selection.

Reminder again: We must seize the opportunity to treat pertussis, because at present, drug-resistant pertussis is the main epidemic in China, so compound sulfamethoxazole is recommended as the first choice for empirical treatment.

Case 2

3 years and 7 months, I saw a doctor on July 13th (Day 2), and my medical history is as follows:

Initial diagnosis of acute laryngitis (mild). Because the symptoms suggest viral infection (especially parainfluenza virus), no pathogenic test was made at the first diagnosis.

The children returned home with high fever that day, and the parents made a quick inspection of the US delegation. The results are as follows:

You see, the US Mission has detected three kinds of "conditional pathogens" quickly, but there is no parainfluenza virus detection project, which makes parents feel strange.

In the next few days, the progress of this child’s illness is worrying.

On the 14th (Day 3), repeated high fever, the highest is 40.1℃.

On the 15th (Day 4), the highest temperature was 40.7℃. I went back to the clinic for targeted sequencing.

On the 16th (Day 5), sequencing showed that:

On the 16th (Day 5), the child developed yellow tears. His body temperature was 39.7℃ during the day and nearly 40.1℃ at 10 pm. My parents contacted me.

Combined with the sequencing results and the change of symptoms, I considered the virus combined with bacterial infection, and started amoxicillin and clavulanate potassium that night.

On the morning of the 17th (Day 6), the body temperature gradually dropped and pus increased. My temperature has been normal since the afternoon of the 17th.

Through this case, we can draw the following conclusions:

1. The Streptococcus pneumoniae strain detected this time is false positive (negated by sequencing).

2. The Pseudomonas aeruginosa detected this time is false positive (negated by sequencing).

3. The Haemophilus influenzae detected this time is accurate (confirmed by sequencing).

4. The parainfluenza virus detected by sequencing is the pathogenic pathogen that causes the initial symptoms of children, but the detection project has been cancelled by Meituan (which has been kept by JD.COM Quick Inspection so far).

5. The sequencing results are helpful for judging the virus combined with bacterial infection, and this result is also the basis for my difficult decision to start antibiotic treatment at 11 o’clock on the 16th.

03

Is home nucleic acid testing accurate or not?

Any new thing can’t be perfect, there will always be some problems that need to be constantly improved and improved.

Since it is an improvement, it should be improved as possible.

For example, it is very good to add pertussis and group A streptococcus detection items to the home quick inspection.

However, the US Mission cancelled the parainfluenza virus detection and increased the detection of Pseudomonas aeruginosa and Klebsiella pneumoniae with low value, which is puzzling.

Pathogen detection is very important for the management of some infectious diseases, so we should have higher requirements, which is not too much.

If the test results are inaccurate, some pathogens will always be false positive, which will not only lead to patients’ (or their families’) worries, but also lead to wrong intervention, increase the doctor’s interpretation cost and waste the doctor’s time.

The two cases I cited earlier are just cases, which are not convincing enough. Whether home nucleic acid is accurate or not depends on a large sample survey.

We can collect enough home nucleic acid and targeted sequencing results, and then analyze the difference of pathogen positive rate; If a patient has done home nucleic acid and targeted sequencing at the same time, the control analysis is more valuable.

Ben WeChat official account plans to write a series of articles to discuss how to manage common upper respiratory tract infectious diseases by home quick check-up.

Here, I especially hope that the testing organization will make this product better. For example, quality control personnel should carefully analyze the test data, find out the reasons for the high detection rate of pathogens such as Streptococcus pneumoniae, resume the detection of parainfluenza virus, and cancel some unnecessary tests.

In order to make a more rigorous evaluation, we collect home nucleic acid test results from readers, and the requirements are as follows:

1. Provide a complete test report screenshot. If there are other pathogen detection reports (such as targeted sequencing or antibody detection results), they can also be provided together. Please cover the patient’s name.

2. Sampling sites (such as throat swab and nasopharyngeal swab) can be provided.

3. Can inform the patient’s age, main symptoms (such as fever, cough, runny nose) and city.

Build a strong public health system and increase the supply of high-quality medical resources
Health of the whole people and enhancement of people’s happiness.

The construction of county medical community has been accelerated, the quality medical resources have been expanded, the public health protection network has been woven tightly, and the health has been guaranteed … This is the personal experience of the broad masses.

General Secretary of the Supreme Leader pointed out: "The most important indicator of modernization is people’s health, which is the basis of people’s happy life. Grasping this matter, people first and life first should be an idea that the whole party and society must firmly establish. "

The pace of building a healthy China is steady. China insists on giving priority to people’s health, promoting the balanced distribution of high-quality medical resources, strengthening the construction of national medical centers, regional medical centers, medical associations and medical associations, continuously improving the service capacity of primary medical institutions, building a strong public health system, striving to ensure people’s health in all directions and throughout the cycle, and constantly enhancing people’s sense of acquisition, happiness and security.

Weave tightly and densely the public health protection net.

"When taking public transportation or going to public places, you can see strict epidemic prevention and control measures." Ms. Zhou, who works in Beijing, said.

In the face of the epidemic in the century, we adhere to the people first, life first, external defense input, internal defense rebound, dynamic zero clearing, constantly adjusting prevention and control measures according to the situation, maximizing the protection of people’s life safety and health, and coordinating economic development and epidemic prevention and control to achieve the best results in the world.

Weave a well-knit public health protection network, and issue the novel coronavirus Prevention and Control Plan (9th Edition). According to the characteristics of the mutant strain in Omicron, the epidemic monitoring, the isolation management of risk personnel, and the demarcation standard of middle and high risk areas were adjusted according to the situation, so as to effectively coordinate the epidemic prevention and control and economic and social development.

Strengthen scientific and technological research on vaccines, rapid detection reagents and drug research and development, carry out emergency examination and approval of vaccines in Covid-19, and actively promote the research and development of therapeutic drugs in Covid-19. Carry out vaccination work in a scientific, standardized, safe and orderly manner, and start the sequential immunization of vaccines in COVID-19.

Promote the establishment of 320,000 village (neighborhood) committees and public health committees to lay a solid foundation for community prevention and control of COVID-19 epidemic. At the end of last year, the Ministry of Civil Affairs, National Health Commission and other four departments jointly issued guidance, requiring all localities to strive to achieve full coverage of the mechanism of public health committees, generally improve their capabilities and effectively play their roles in about two years, and initially establish a grass-roots public health management mechanism that dynamically connects normal management with emergency management.

Improve the level of equalization of basic public health services. This year, China’s per capita financial subsidy standard for basic public health service funds reached 84 yuan, and 5 yuan was added as a whole for basic public health services and epidemic prevention and control in primary medical and health institutions. We will continue to provide all urban and rural residents with 12 categories of national basic public health services and 19 services, including prevention and treatment of endemic diseases, prevention and treatment of occupational diseases, maternal and child health, and combination of medical care and nursing.

Carry out the patriotic health campaign in depth. Since the beginning of this year, the activities of "building a healthy home" have been widely carried out in various places, guiding the residents to develop a civilized, healthy, green and environmentally friendly lifestyle and creating a clean, civilized, orderly, healthy and peaceful environment. The environmental quality in urban and rural areas has improved significantly, and various health and environmental indicators have continued to improve.

Accelerate the implementation of the Healthy China Action. Focus on all-round intervention of health influencing factors, maintenance of life cycle health, prevention and control of major diseases, and promote the transformation from treating diseases as the center to people’s health as the center. At present, the average life expectancy of Chinese residents has reached 78.2 years.

Accelerate the expansion of high-quality medical resources

A few days ago, Yangyang, a 9-month-old child, was taken to Ningxia Children’s Hospital for fever of unknown reasons. After diagnosis, Yangyang needs surgery as soon as possible. However, the hospital does not yet have the relevant surgical conditions. At this time, the experts from the First Hospital of Peking University, who are helping their counterparts in this hospital, immediately turned to the "rear area" for help. On the same day, the First Hospital of Peking University decided to open a green channel and directly refer the children to Beijing for surgery. After 14 hours of transshipment, the child arrived in Beijing. The children’s intensive care unit team of Peking University Hospital completed the preoperative evaluation and preparation that night, and the next day completed the surgical debridement and subarachnoid drainage of spinal cord infection focus. After the operation, the child returned to the ward safely and was in good mental state. The parents of the children said excitedly, "I can’t believe I finished the operation so soon!"

In May this year, Ningxia Women and Children’s Hospital, the first hospital in Peking University, was listed as the third batch of national regional medical center construction projects. The hospital was jointly established by the People’s Government of Ningxia Hui Autonomous Region and the First Hospital of Peking University, and is located in the hospital of Ningxia Maternal and Child Health Hospital (Ningxia Children’s Hospital).

The joint efforts of the two places to treat difficult and severe patients fully reflect the advantages of the national regional medical center.

In recent years, relying on high-level hospitals, China has set up national medical centers and national regional medical centers to improve the overall and regional medical service capabilities. In view of the flow of people seeking medical treatment in different places and key diseases, 10 national medical centers with professional categories have been set up, 50 national regional medical centers have been built, and 15,000 medical associations have been established.

Xu Shuqiang, director of the Department of Economic Restructuring of National Health Commission, said that China will continue to promote the expansion, sinking and balanced distribution of quality medical resources. At the national level, promote the establishment and construction of national medical centers and national regional medical centers, and reduce cross-regional medical treatment. The construction of national regional medical centers will strive to cover all provinces in China by the end of this year. At the provincial level, 120 provincial regional medical centers will be built to improve the provincial diagnosis and treatment capacity.

Tamp the bottom of primary health care network

Not long ago, a villager in meishan town, Datian County, Sanming City, Fujian Province had a sudden myocardial infarction. The medical staff of Meishan Branch of Datian County General Hospital uploaded the description records and electrocardiogram of the patient’s family members to the chest pain center of the general hospital. The first-aid team of the general hospital instructed local doctors to thrombolysis for patients and successfully implemented telemedicine treatment.

The remote ECG diagnosis system of Datian County General Hospital covers all grass-roots branches, and county hospitals provide ECG diagnosis reports for grass-roots branches, which better solves the problem of insufficient diagnosis experts in grass-roots medical and health institutions. Datian County has broken the administrative barriers of medical and health institutions at the county, township and village levels, integrated medical and health resources at the county level, and undertaken basic medical and public health services for the residents of the county, thus consolidating the basic medical and health service network.

Since the beginning of this year, China has accelerated the construction of an orderly new pattern of medical treatment and diagnosis. The capacity of primary medical and health services has been continuously enhanced, and the proportion of primary diagnosis and treatment has remained above 50%. The people have a 15-minute medical and health service circle around them, and more experts are sitting at their doorsteps, making it more convenient, more affordable, more efficient and smoother to see a doctor. It has gradually become a reality that serious illness is solved in this province, general diseases are solved in cities and counties, and headaches and brain fever are solved in rural areas.

The construction of a close county medical community has been fully promoted. Pilots were carried out in more than 800 counties (cities, districts) across the country, and medical insurance was packaged and paid, which promoted the sinking of resources and promoted the integration of medical care and prevention. While guiding the medical community to improve its medical capacity, it will shift more work to disease prevention, and the proportion of inpatients in the county and the proportion of residents’ medical insurance reimbursement will increase steadily. Strengthen telemedicine and informatization construction, and gradually realize grassroots inspection, superior diagnosis and service homogeneity. The efficiency of medical services in the pilot counties has been improved, and the rate of medical treatment within the county has exceeded 90%. The role of "strengthening the county and strengthening the grassroots" has begun to appear.

Innovative development of family doctor contract service. All cities and counties (cities, districts) in China have basically implemented family doctor contract service, and more than 420,000 family doctor teams have been set up to provide medical and health services including long-term prescriptions and on-site services for contracted residents, especially the chronically ill and the elderly. Promote the high-quality development of family doctor contracting services, and the coverage rate of family doctors in key populations exceeds 70%.

The construction of community hospitals is in full swing. By the end of 2021, more than 2,600 community hospitals had been built in China. National Health Commission proposed to continue to develop community hospitals this year, promote the construction of about 500 new community hospitals, select and strengthen the capacity building of a number of central hospitals, and strive to achieve the basic standards of service capacity in grassroots medical and health institutions during the Tenth Five-Year Plan period, and strive to narrow the gap between urban and rural development, so as to facilitate the people to obtain convenient, efficient and high-quality services nearby.

People’s health is the foundation of social civilization and progress, and it is an important symbol of national prosperity and national prosperity. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, more than 1.4 billion people in China are full of yearning for a healthy and beautiful life, and are marching towards a new journey of building a healthy China with a more high-spirited attitude. (Reporter Bai Jianfeng)

　　On the afternoon of September 27th, the State Council Press Office held a routine briefing on the State Council policy, introducing the situation of supporting the stable development of foreign trade and answering reporters’ questions.

　　Wang Shouwen, international trade negotiator and vice minister of the Ministry of Commerce, said that from January to August, China’s foreign trade import and export reached 27.3 trillion yuan, a record high. However, foreign trade is facing some new uncertainties, and the growth of external demand is slowing down, which is the biggest uncertainty facing foreign trade at present. This is reflected in the slowdown in the economic growth of major economies such as the United States and Europe, and the decline in the growth rate of global trade in goods.

　　In order to cope with this background and promote the steady growth of foreign trade, the CPC Central Committee and the State Council made timely arrangements to create a good environment for foreign trade enterprises and create good conditions for the goal of maintaining stability and improving quality of foreign trade.

　　From January to August, China’s mechanical and electrical products accounted for 56.5% of foreign trade exports, while automobile exports increased by 57.6% and solar cell exports increased by 92.6%. It is worth noting that in August, the export growth of China to other RCEP member countries reached 23%, which was 11.2 percentage points higher than the overall foreign trade export growth rate in August. Free trade agreements, including RCEP, came into effect on January 1st this year, which played a very important role in promoting the development of China’s foreign trade.

　　Generally speaking, despite the background of slowing or even weakening external demand, we are confident that foreign trade will achieve positive growth in the second half of the year and make positive contributions to the recovery of the national economy through the growth of foreign trade.

The unfinished building was once a special group with 82 scars in the city, and a case was vigorously rectified to help it regain its life.

A luxurious office building surrounded by 16 huge Roman columns among the overgrown weeds; The modern intelligent office building in a prime location has been established for more than 10 years, but it just stays on the drawings, and the site is still a muddy construction site …

Like many cities in China, many commercial development projects in Guangzhou came to a standstill in the 1990s due to the break of the capital chain and other reasons, and became "unfinished buildings" covered with moss, like a dazzling "scar" in the bustling downtown area.

Solving the problem of uncompleted residential flats and healing urban scars has become a key livelihood project that successive governments in Guangzhou have attached great importance to. City leaders personally took the lead and set up special work leading groups twice to vigorously promote the disposal of "uncompleted residential flats" and untie the deadlock one by one in batches on the basis of respecting history and complying with laws and regulations. At present, 90% of the 82 "uncompleted residential flats" in Guangzhou have been revitalized and become a beautiful landscape in the city.

Cause:

Capital chain fracture

It’s a rotten tail commonality

According to an urban construction person, at that time, a large number of overseas businessmen were optimistic about Guangzhou’s prospects and came to invest. Some local investors also aimed at development opportunities and bought land for real estate development. Guangzhou ushered in a real estate development boom. "Some developers have no financial strength and want to borrow project financing or even empty hands. The break of capital chain is a commonality of these properties."

The reporter learned that Conghua Hot Spring Villa was put on sale in the 1990s. In 1996, it was the first to "buy a villa and send it to a villa". At that time, the price of the villa was about 5,000 yuan/square meter. After the sale, it was not ideal, and the investor withdrew its capital and then it was unfinished. After the outbreak of the financial crisis in 1997, the developer’s capital chain was broken. After Zhongcheng Plaza, now known as Guangzhou Sinopec Building, completed 80% of the glass curtain wall on the external wall, the construction unit was in arrears with tens of millions of yuan, and the building stopped working. The building entered the "unfinished mode".

In the prosperous commercial area of Changgang Road in Haizhu District, the name of Darby International Business Center was "Hong Kong and Macao Jiangnan Center" before it was revitalized, which is also an unfinished building that has stood for many years. In 1993, the foundation was laid, and it was stopped when it was built on the 29th floor. Then it changed hands many times and changed its name many times. After it changed hands again in 2006, it ended badly because of problems in the capital chain.

Some people say that every unfinished building can be made into a movie: some investors have lost their lives for it. In 1995, a partner jumped down from the unfinished Jiangnan Center in Hong Kong and Macao and made a sensation. Zhongcheng Plaza, once known as "the first unfinished building in China", dismounted Huang Songyou, former vice president of the Supreme People’s Court, and Yang Xiancai, former director of the Executive Board of Guangdong Higher People’s Court. Hailian Building, which was unfinished shortly after the foundation of scenery, also sent Xu Yunian, former vice minister of Guangdong United Front Work Department, to prison. Every time I look at these unfinished buildings from afar, many people who have experienced them are crying.

Impact: Some relocated households did not move back until they died.

In 2003, Liu Liansheng, who just graduated from a university in Wuhan, was still very clear about the "wonders" of the city when he first came to Guangzhou. "As soon as I got out of Guangzhou Railway Station and turned to Huanshi Road, I saw a tall, magnificent and square building in a grassy field." "After working in Guangzhou for many years, I still see this mysterious house in its original place, surrounded by high walls, like a luxurious office building, and no one has entered."

These uncompleted residential flats once became "the scar of the city" and "the stain of the environment" in Guangzhou. The reporter inquired about the relevant information and learned that most of these unfinished buildings are concentrated in the central city, and they are located in downtown and prosperous places. Take Wanlinghui before the revitalization as an example, which is located in the core business district of Tianhe, next to Zhengjia Square, and can be described as a prime location; Zhongcheng Plaza, once known as "the largest uncompleted residential flats in China", is located at the junction of Tianhe North Road and Tiyu West Road. The surrounding CITIC Plaza, Mayor Building and Victoria Plaza are all important commercial places in Guangzhou, and the property prices are high.

"These unfinished buildings not only affect the surrounding environment and the image of the city, but also make valuable economic resources idle and wasted. More importantly, they lead to a large number of letters and visits, which can easily lead to social instability." An industry insider admits that the uncompleted real estate is most affected by the relocated households and buyers who used to live here, resulting in their long-term inability to move back and resettle. The short period is more than 10 years, and the long period is more than 20 years. "Some resettlement households have not even moved back to the new building until their death. Many unfinished buildings have pulled up banners with tens of meters of white cloth and black characters, which is heartbreaking."

Crack: as a key project, many departments work together.

In 2002, the Guangzhou Municipal Government put forward the goal of "eliminating uncompleted residential flats". In 2003, Guangzhou Municipal People’s Congress issued the resolution on the implementation plan of "Proposal on Improving Unfinished Buildings as soon as possible", which proposed that solving and preventing "Unfinished Buildings" would be an important task in urban planning, construction and management in the future. Chen Jianhua, the mayor, gave instructions on "uncompleted residential flats" twice. "The reasons for the formation of uncompleted residential flats are complicated. Please ask the Project Construction Committee to set up a task force to take the lead, analyze each project one by one, and speed up the progress of revitalization. Strive to clear the old accounts as soon as possible, and no new accounts will be owed. Standardize urban construction and project management. " "It is a major measure to take the hard bone of’ uncompleted residential flats’ to administer according to law and build a society ruled by law."

According to the person in charge of the Guangzhou Municipal Commission of Housing and Urban-Rural Development, Guangzhou has twice set up a special work leading group to deal with the "uncompleted residential flats" in Guangzhou. "Some unfinished buildings have convened more than 10 departments and held more than 10 coordination meetings. It is common to open from morning till night." A person in charge of urban construction who has participated in the revitalization project of uncompleted residential flats for many times told reporters that he has investigated almost every registered uncompleted residential flats in Guangzhou, decided on the revitalization plan, and is also responsible for follow-up implementation. "It is easy to build a new building, but it is difficult to revitalize an old building."

According to the person in charge of the Guangzhou Municipal Commission of Housing and Urban-Rural Development, the causes of the "uncompleted residential flats" are very complicated, including internal reasons, such as shutdown due to broken capital chain, unfinished residential flats due to enterprise bankruptcy, and external objective reasons, such as being sealed up by the court due to debt disputes and difficult to achieve economic balance due to planning adjustment. To untie the fast knot, we must clarify the causes of the rotten tail and put forward a targeted revitalization plan.

"Every unfinished building has commonalities and characteristics. It is necessary to jump out of the old thinking and not play cards according to the routine." The person in charge also introduced that Guangzhou’s experience in revitalizing unfinished buildings has attracted many cities such as Zhuhai to "learn from the experience". He concluded that it is not easy to revitalize these unfinished buildings in a short period of time. "It is necessary to deal with them in batches first, and it is necessary for multiple departments to work together.

The city once had

82 "uncompleted residential flats"

Revitalized 47 "uncompleted residential flats" projects

Zhengjia Oriental International, Lujingtai, Jinglong Pavilion, Fanying Pavilion, Qiaokang Building, etc.

Projects that are being revitalized

Ten projects have entered the construction or sales stage.

Hailian Building, Famous City Commercial Plaza, etc.

13 projects go through administrative approval procedures according to procedures.

Xinhao Building, Donghu Xuan, etc.

10 cases have entered the execution stage of judicial disposal.

Fudu Building has been auctioned off.

Fuxin Plaza is revitalized by new creditors.

……

Revitalize oneself through enterprise restructuring

Zhongshui Plaza was reorganized and revitalized by the parent company of the major shareholder, the Three Gorges Group. The Three Gorges Group agreed to start the procedure as soon as possible, but the progress was slow.

"This means that it is not easy for more than 90% of uncompleted residential flats in Guangzhou to be properly handled or revitalized." An urban construction person told reporters.

"The projects that have not been revitalized at present are real’ hard bones’, and there are many historical problems such as legal relations and disputes over creditor’s rights and debts, incomplete project procedures, lack of information and planning adjustments, and so on." The person in charge of the Guangzhou Municipal Commission of Housing and Urban-Rural Development said that the next step will be to coordinate the planning department to actively list the planning and approval problems of the projects concentrated in the planning and approval stage and propose solutions, and coordinate the courts at all levels to step up the judicial disposal of the projects so that the projects can enter the administrative approval and resume work as soon as possible.

Where did the uncompleted residential flats go?

9 years of unfinished business in Zhongcheng Square

Located at the junction of Tianhe North Road and Tiyu West Road, it was the Guangzhou Big Mac office building under construction. After the construction started in 1992, many Hong Kong and Macao investors snapped it up, and the price soared to more than HK$ 30,000 per square meter at that time. When the Asian financial crisis broke out in 1997, the developer’s capital chain was broken, and the project became "the first unfinished building in China". According to reports, the debt dispute of the building is complicated. In the past 15 years, more than 300 lawsuits have been fought. After several changes of hands, in mid-2006, Sinopec Group Corporation bought a tower in Zhongcheng Plaza for about 10 billion yuan, and officially renamed Zhongcheng Plaza as "Sinopec Building".

Heyin Square has been unfinished for 7 years.

In 1998, Heyin Plaza, located next to Huanshi East Road Garden Hotel, was officially started. It was named "Dapeng International Plaza" and was the "Chief Office Building of Huanshi Road Business Circle in Guangzhou", which attracted a lot of Hong Kong capital. When the financial turmoil struck, the developer Dapeng Real Estate abandoned Heyin Plaza and took over Zhengjia. In 2002, the project eventually became "the second unfinished building in Guangzhou".

Hong Kong Ruian Group once announced that it planned to acquire Heyin Plaza for 1.388 billion yuan. In January 2009, Ruian Group suddenly announced that it would abandon the acquisition, and the revitalization of Heyin Plaza was frustrated. At the end of 2009, Dapeng Real Estate raised enough funds to let Heyin Plaza resume work and officially revitalize it. It officially opened in early 2011 and changed its name to Zhengjia Oriental International Plaza, which is currently one of the subsidiaries of Guangzhou Zhengjia Group.

Fanying Pavilion has been unfinished for more than 7 years.

Fanying Pavilion is located at No.130, Binjiang West Road, Haizhu District. It was originally developed by Guangzhou Hengjing Real Estate Investment Co., Ltd. (hereinafter referred to as Hengjing Company). In 2003, it stopped working. In 2010, due to debt disputes, some houses were auctioned by Guangzhou Haizhu District People’s Court, and Guangzhou Yicheng Jiangzhao Real Estate Co., Ltd. (hereinafter referred to as Jiangzhao Company) won the bid to rebuild Fanying Pavilion.

Since then, due to the non-cooperation of the executed person Hengjing Company, the buyer Jiangzhao Company was unable to go through the relevant procedures of reconstruction, such as engineering, water and electricity, fire inspection and acceptance, filing of completion inspection and filing, which affected the reconstruction, and 102 small owners who bought houses were unable to take over the building and apply for real estate licenses, causing small owners to be dissatisfied with petitions.

In 2010, the Guangzhou Municipal Construction Committee held two coordination meetings, and reached an agreement with the participating functional departments: from the overall situation of protecting the rights and interests of 102 small business owners who have purchased houses and maintaining social stability, all relevant functional departments should support the bidders to complete the procedures as soon as possible and then return to work. As Haizhu District Court has explicitly agreed to go through the formalities of applying for reconstruction in the name of Jiangzhao Company, Haizhu District People’s Court will issue a notice of assistance in execution to the relevant departments. On June 12, 2010, Guangzhou Municipal Construction Committee and Guangzhou Mediation Office jointly held another meeting on "Speeding up the related work of rebuilding the unfinished building of Fanyingge", and determined the co-organizer departments and handling methods for all aspects of the procedures for rebuilding and reporting, so that the problem could be finally solved. The building has been built and accepted, and the owner has moved in and handled the real estate license.

Xichang Electronic City has been unfinished for 9 years.

The Xichang Electronic City Project is located at No.81 Dongfeng West Road and Zhongxing Cross Section, and was developed by Guangzhou Lihong Real Estate Development Co., Ltd. The project covers an area of about 3,200 square meters, with 13 floors and a total construction area of about 23,000 square meters.

In 1995, the construction unit began to apply for construction projects. The main structure construction was completed in 2000. In 2003, due to the financial problems of the construction unit, the work was stopped, and the main building structure and external wall were completed when the work was stopped, and the equipment installation and internal decoration were not completed. In 2011, Lihong Company began to straighten out the relationship and restart the project. In 2012, the architectural design of the project was reviewed from the perspective of respecting history, coordinated by the Guangzhou task force to deal with uncompleted residential flats.

Special feature of 1905 film network As an audience, what content of a movie will you be attracted to first?Everyone will have their own answers.Perhaps the main lineup can attract audiences with the reputation of past works; Inductive posters posted everywhere can also be "brainwashed" and impressive; And take the film.ContentTrailer, relatively more concrete.After all, the trailer can more directly present a film’s style, plot and other effective information. Even many viewers learned about a movie through the film notice in the cinema, and silently planted grass.

Although in the eyes of many people, the trailer is just a propaganda material, which undertakes the function of advertising, for the staff, preview editing is the closest thing to the creation of film content among all kinds of propaganda materials at present.It seems that in many people’s cognition, the trailer is made by the director and the film editing team themselves. Of course, this situation does exist, but it is not entirely the case.

　

The so-called industry has specialization. With the development of China films, promotional materials companies are increasingly divided in the market, including poster companies and video companies, among which trailer companies, tidbits companies and short video companies are even divided. Of course, there are also many companies that can set foot in all the corresponding fields.Looking at the whole film circle, the trailer industry is still relatively young, and only full-time companies have been established since about 2010, with a development of more than 10 years. Nowadays, with the development of the film industry, the production of trailers has entered another track.

　

A heavier and shorter trailer

The word "preview cheating" often appears in some online comments. Obviously, these trailers have successfully deceived the audience into the cinema.

　

In other words, among the factors that affect the audience’s expected management of movies, trailers account for a huge proportion. A movie usually has more than four trailers, and those films in important periods such as Spring Festival and National Day have a greater demand for the number of trailers.

　

Among these trailers, which one is the most important?

　

The company "Youmingtang" has participated in other film projects. Co-founder Xu Wenbo told us that from the data given by various platforms at present, the final preview is usually the most clicked. "A big reason comes from that most viewers usually take the initiative to open a trailer to understand the film before considering buying tickets, and at this time, most of the tickets are recommended and displayed by the ticketing platform."

This phenomenon also makes the ultimate notice a "mountain" in the eyes of practitioners.

　

"It is not difficult to simply cut out the plot, but a good final preview needs to use colorful ideas and forms in a short time to make the plot catch the audience." Lin Mingtao, director of Hengye Film Video Center, pointed out the difficulties to us.

　

Liu Wenpu, the founder of Liuhe Century, who has participated in other projects, said that besides the final preview, the first preview is also not easy. "That is the first video material to meet, and the audience will have a certain understanding of the film after watching it. And the content of the video comes from the movie itself, which is absolutely impossible to fake. The most important thing is that this preview will be the longest in terms of playing cycle, and the responsibility of natural bearing will be different. "

　

He also mentioned that with the development of entertainment platform, film marketing methods are no longer routine, and each film has different needs for the definition and function of the first preview.

　

It is true that we can see from the first preview of various films released at present that some of them are still the same as in the past, and the film side seems to let the audience quickly grab the selling point of the film by determining the schedule and other information; Others let the audience remember the film first through various more innovative ways, or directly through plot fragments, and then use other contents to let everyone understand it slowly.

　

My People，My Country’s first trailer was one of Xu Wenbo’s impressive trailers. "This trailer was released on July 28, and it actually started working in mid-June."

　

The film was a rare patchwork film at that time. "It took us quite a long time to weaken the sense of patchwork, and it also dispelled everyone’s understanding of the main theme film. In the early stage, we did a lot of research and found that the general audience was more interested in the unit, so we took it as a main body, and sang a My People，My Country to lead to other time nodes. At the same time, we rewrote the music and presented every historical moment. "

　

Judging from the later discussion, this trailer is a success.

Although the idea of trailer editing has been slightly adjusted with the changes in the current entertainment market, the purpose of finally letting the audience find better movie selling points has not changed. It is difficult to find a clear explanation for this change. The biggest consensus is that with the rise of short videos, they often face the same feedback when making them, "cut them as short as possible."

　

Make a decision! The trailer is cut like this

Most movies will be fermented after 1-2 months of publicity, which also gives the publicity team and trailer team the opportunity to "try and make mistakes".

　

Several trailer producers have told us that although they and the propaganda team will try their best to think of various selling points in the early stage, after each trailer is issued, the comments of netizens can always give them some new ideas and avoid inappropriate content in time.

　

Every time Xu Wenbo cooperates with the director, everyone will constantly use various trailers to run in with the market. "We will change our marketing strategy at any time according to various public opinions and previously released data." However, this does not mean that the film promotion depends on data algorithm analysis, but more on emotional classification, from which the audience can find the empathy points found in the film materials.

Then, who will make the final decision on the trailer production of a movie?

　

Generally speaking, the trailer production of most domestic films is often involved in the late stage and near the end of the film production. However, at present, with the changes in the film market, many projects have been involved from the shooting period and even the early stage. Liu Wenpu told us that at present, they have a team working on a film production crew.

　

Of course, such projects are often head projects, and there are very strict plans for publicity and distribution.

　

At present, many filmmakers and trailer teams cooperate in a fixed way. Except for companies such as Light Film and Hengye Film, which have their own special video vision teams, most of them are tacit understanding and trust accumulated over the years.

Of course, with the rise of the trailer industry, the strength of many young companies can not be underestimated, and it is often the case that trailer companies conduct "competitive presentation". Some filmmakers will hand over all the trailer business to a single team, while others will choose according to their plans and hand over the appropriate content to the relevant teams.

　

Usually, in the direction of the trailer, the director has the relatively main decision, but the propaganda team will still give the director relevant opinions in combination with the market situation.

　

The director doesn’t like to put the best content in the trailer, but prefers the fried content … … Every director will have his own preference. Liu Wenpu also told us that Tsui Hark is one of the few directors who can modify the content of materials by himself. "His hands-on ability is very strong."

　

And in the trailer, they have their own ideas of this generation of "online directors".

　

For example, during the publicity period, after the intensive publicity of the film in the past year, many contents have been exposed almost. When facing the release, Chen Sicheng found a non-trailer team to edit. "Even some people are not in the film circle, but in the advertising circle. These people have brought some new ideas to the film promotion."

Lin Mingtao also verified to us Chen Sicheng’s rigor and carefulness in the trailer. "He has already clearly defined the ideas of some trailers from the time of shooting, and even in the middle of filming, he has already completed the trailer shooting."

　

The trailer is not simply edited according to the feature film. At present, many head projects will be "tailor-made" for the trailer during the shooting process.

Better and more realistic trailer

Should the trailer make an illusion and trick the audience into the cinema?

　

This question was thrown to every trailer creator by us. Everyone’s point of view is still the same, "you can’t destroy the temperament of the film itself." Trailers can "cheat", but this kind of "cheat" is to strengthen the advantages of the film itself.

　

Lin Mingtao is currently serving art cinema. "When we cut it, it will be between commercial films and non-commercial films. For example, in See Nara again, we will focus on the topic of mother-daughter feelings and orphans in World War II. This is a commercial topic, but the overall style will definitely retain the original temperament of the film."

Including their past participation, "we will strengthen the legendary content of the original site in the trailer and increase the suspense, which will arouse the curiosity of the audience."

　

In addition to editing creativity, many teams will make great efforts in music and other aspects, and music copyright is also the biggest export of a trailer cost. Liu Wenpu told us that they had spent 80,000 yuan to find a suitable tune in order to edit the preview of "One Warriors"; The Xu Wenhao team also spent nearly 200,000 RMB on the production of light music for the trailer of My People My Homeland Zhonghe Unit. These expenses do not include the mixing work in the later stage of the trailer.

At first glance, these costs are already "sky-high" for a preview material with a communication cycle of only one week, but compared with the "a poster worth 100,000 yuan" that was often mentioned in the past, this cost is not so high.

With the development of China’s film industry, previews, posters and other film materials are closely related to it. With the dedication and content support of these practitioners, it is possible to further broaden and innovate the technology and concepts of filmmakers.

　　Cctv news: On May 26th, after watching the sumo competition, Japanese Prime Minister Shinzo Abe and Trumps had dinner at the stove-end restaurant in Benmu, Tokyo. According to a CBS reporter, the four enjoyed five dishes including roast beef and vanilla ice cream. The video shows that after the chef prepares the baked food, he hands it to Abe Zhaohui, Shinzo Abe, Melania and Trump in turn.

1905 movie network news Organized by the movie channel, Jackie Chan and other 100 stars initiated and participated in the "Fight Against Poverty — — The "Starlight Action" public welfare project officially launched its third stop in Jiangcheng Hani and Yi Autonomous County, Yunnan Province. Jiangcheng County is located in the south of Yunnan, which is named after Li Xianjiang, Man Laojiang and Meng Yejiang. It also borders Vietnam and Laos, hence the saying that "one city connects three countries".

On September 15th and 16th, the project team led by Cao Yin, director of the program center of the film channel, and the actor Huang Xiaoming’s team will complete the poverty alleviation research activities here. The research work of this trip is mainly divided into three parts: visiting the trail of Asian elephants to find a way to get along with each other, visiting poor families in the whole wasteland, and conducting on-the-spot and detailed investigations on the local tea industry.

This "fight against poverty — — The poverty alleviation research of Starlight Action focuses on ecological poverty alleviation and industrial poverty alleviation, and discusses the benign interaction between ecological protection and economic development. The arrival of the team has been warmly welcomed by the local people. The Propaganda Department of Yunnan Provincial Party Committee and Pu ‘er Municipal Party Committee and Municipal Government attached great importance to it. They said, "Fighting poverty — — It is a good thing that "Starlight Action" focuses on local problems, attracts social attention with the help of the influence of stars, publicizes local characteristic industries and inspires people.

　

Huang Xiaoming explores the tracks of Asian wild elephants on the spot.

Name the newborn elephant baby "Nuannuan"

　

After carefully reading "The Battle against Poverty — — After the information provided by the advance team of "Operation Starlight", Huang Xiaoming chose the "wild elephant" in Jiangcheng, Yunnan Province as the research direction of precision poverty alleviation. In addition to the natural protection value of this precious and rare wild animal, Huang Xiaoming thinks that perhaps through field visits, we can further explore the eco-tourism resources and help the local people find a unique way out of poverty.

In fact, nearly a quarter of the Asian elephants in the world live in Jiangcheng. Although they are very cute as rare animals, they trample on food in the process of migration and foraging, threatening the personal safety of villagers, and indeed bringing troubles to the local government and villagers. How to protect human life and production resources while protecting Asian elephants? How people and elephants live in harmony is also the answer that Huang Xiaoming wants to pursue in this trip.

On the morning of September 15th, the poverty alleviation research team set out for Dajiaoshu Village, Kangping Town. Soon after getting off the bus, Huang Xiaoming and his party passed a field with signs of destruction. According to the inspector of the same trade, three or four days ago, a group of wild elephants "passed by" from here, gnawing the corn planted by fellow villagers, leaving big footprints on the land on both sides. Following the footprints, Huang Xiaoming felt even more distressed when he saw the trampled farmland, and repeatedly apologized to the villagers for the elephant. The elder sister of the villagers on the side said with open mind, "Although I am very distressed and even a little scared, there are so many wild elephants living here, which also shows that our environment is good, and these elephants look particularly simple and honest."

Huang Xiaoming was very moved by the villagers’ love for elephants, but he was still very concerned about whether everyone’s life and property safety had been effectively guaranteed. At present, the local authorities have strengthened the early warning and monitoring of the whereabouts of wild elephants. In addition to timely issuing notices through WeChat and other communication methods, each village group has also installed high-pitched broadcasts to timely notify the villagers to protect their personal safety.

According to the inspector’s 24-hour careful monitoring, they found that there were 23 wild elephants near the villagers’ group recently. Along their tracks, Huang Xiaoming and the research team further explored the mountains along the road. With the help of drone equipment, they successfully monitored this group of wild elephants under the canopy. At the sight of the picture, Huang Xiaoming could not but let out a scream.

In the lens, elephants are playing and foraging in the Woods. According to the drone aerial photographer, most of the elephants are females, and several males often struggle for higher ethnic status. Huang Xiaoming listened to the introduction of the aerial photographers with relish, and under the guidance of professionals, he personally piloted a drone for observation. In the process, he also found a baby elephant playing under his mother’s stomach. This is a little male elephant, which was just born four months ago.

The inspectors warmly invited Huang Xiaoming to give the baby elephant a name, which made him both surprised and caught in a little tangle. After thinking about it, Huang Xiaoming chose the name "Nuannuan", which is the deepest feeling he got from the local people after he came to Jiangcheng — — Simple, kind and warm, including in the face of wild elephants, these villagers also chose tolerance and protection, which made Huang Xiaoming very touched.

After following up for a certain distance, Huang Xiaoming and the team did not continue to approach the wild elephant for the sake of protecting the safety of the wild elephant and the personnel themselves. The data shows that in recent times, the distance between people and elephants did not exceed 100 meters. The good ecological environment and rare wild elephants made Huang Xiaoming very excited at the end of the first inspection tour, and strengthened his confidence in the poverty alleviation plan for the development of local ecological resources.

At the same time, with his personal experience and understanding of the local situation, he also thought more seriously about how to coordinate the development of "man and nature" in Jiangcheng County, especially the relationship between man and image, so as to combine nature protection with improving the lives of local people and accurately helping the poor.

　

Huang Xiaoming expressed condolences to farmers for emotional tears.

Thinking about the way of harmonious and sustainable development of human-image relationship　

　

According to the previous "fight against poverty — — According to the investigation results of the advance team of Operation Starlight, the activity area of wild elephants in Jiangcheng County is about 500 square kilometers, involving 93 villagers’ groups and more than 19,000 people of more than 4,800 households. The direct economic loss caused by wild elephants to the local people exceeds 40 million yuan, and the indirect loss is even more incalculable.

After the Asian elephant visit, Huang Xiaoming rushed to visit.The poor family in the whole wasteland group is a family that has been harassed by elephant group activities. Yang Xiaobao, a grandfather at home, is 87 years old this year, and his daughter is in poor health. Only his grandson Dao Lingqiu is left in the family, and several people rely on him to grow tea to feed.

When he arrived at the door of the poor people, Huang Xiaoming repeatedly said hello to everyone and gave them a thoughtful Mid-Autumn Festival gift. Grandpa grabbed his hand, and his simple emotion instantly infected Huang Xiaoming’s mood. He greeted "Grandpa" while holding each other tightly.

The house where the old people live is relatively old, the wooden beams have decayed and moth-eaten, and the sleeping place is often wet because of heavy rain and water leakage. On the table in the center of the main house, there are many medicine bags, which are the traditional Chinese medicine that mother Yang Huixian takes every day. For this family, which lacks labor, has a single source of income and an annual income of only 10,000 yuan, the monthly expenditure of nearly 1,000 yuan on medicine has caused a heavy economic burden. Since the establishment of archives in 2014, it has not yet achieved poverty alleviation. Talking about all kinds of difficulties, Yang Huixian and the children cried. Huang Xiaoming comforted them, but she couldn’t help crying.

Knowing that there are some problems in tea sales, such as poor promotion channels, poor popularity, and low sales price, Huang Xiaoming actively stated that he would use his own strength to help Jiangcheng County promote the tea industry and regard it as his second hometown: "Of course, my own strength is limited, and we will also use the’ tough battle against poverty — — Starlight Action’, let more people join in and find solutions together to help you solve your difficulties. "

This activity has attracted wide attention from all walks of life. The number of live viewers is nearly one million, and the number of topic discussions exceeds 47 million. Netizen’s message: "Thank you’ Starlight Action’, the outstanding Xiaoming brother, for supporting charity and guarding Yunnan."

　

After the investigation on 15th, Huang Xiaoming and his team will continue to learn more about the development of tea, nuts and other industries in Jiangcheng County on 16th.

　

　"Fighting poverty — — The whole activity of "Starlight Action" was broadcast exclusively by JD.COM, and supported by e-commerce platform for poverty alleviation. The whole event was sponsored by Huawei bracelet B5.

On October 4, Yang Ying was on the hot search for four consecutive days due to the "Crazy Horse Show" issue. But she herself has remained silent, neither admitting that she has seen it nor denying the incident, which makes the incident confusing. Unexpectedly, the comment section of her ex-husband Huang Xiaoming was completely blown up, and the nationality of Yang Ying’s father was also exposed. Yang Ying’s remarks about nationality have caused a lot of controversy!

Huang Xiaoming’s comment box is missing.

Huang Xiaoming originally enjoyed the National Day reunion with his family. Unexpectedly, his ex-wife Yang Ying was already on the cusp of the trend. Many netizens flocked to Huang Xiaoming’s comment area to leave a message saying: Brother, the most correct decision in your life is to divorce AB!

Some netizens lamented that Huang Xiaoming had foresight. Fortunately, he and Yang Ying separated, otherwise they would have been scolded this time.

The resources that Yang Ying and Huang Xiaoming have after their divorce are really hard to describe. She started as an 18-line model. After falling in love with Huang Xiaoming, she not only opened up the mainland market, but also ushered in a wedding of the century that shocked the entertainment industry.

Now, although Yang Ying’s case has not been clearly resolved, there is news that her show has been investigated, and even her video has been officially deleted. Even if you are not banned, your reputation and resources should be affected in the future, right?

Yang Ying’s father’s nationality exposed

Ms. Yang has said that she is of mixed Chinese-German descent and that her father is German, although some netizens have revealed that her father holds a German passport and is actually of German-Indian descent.

What made netizens angry was that although their father was obviously Indian, he deliberately ignored and blurred the concept. This kind of behavior is indeed shameful.

Now, because of a "Crazy Horse Show" farce, everyone around him has been involved, which can be said to be more gain than loss. If you really haven’t been there, wouldn’t it be better to publicly deny it?

The case has been going on for so many days and has become so ugly. Do you really not want to answer? If this goes on, the reputation is really irreparable, isn’t it?

Responsible editor:

The trend of new energy is booming. Among several types of new energy vehicles, extended-range electric vehicles have become the new favorite. Such vehicles can not only enjoy the policy benefits of new energy vehicles in most cities, but also make up for the shortage of mileage anxiety of pure electric vehicles. In the camp of extended-range electric vehicles, AITO and Ideality are representative brands. The former has launched the first technologically luxurious intelligent electric drive SUV—AITO Wenjie M5, which is being delivered in 36 cities and more than 100 user centers. The latter has a high market popularity in Li ONE, so how to choose these two models? This paper tells you the answer by comparing the hard power of the two.

Comparison of extended range platforms: AITO-bound M5 has a longer comprehensive battery life and a smoother range extender.

AITO Interface M5 comes from Celeste pure electric drive range extension platform (DE-i), which contains a 1.5T four-cylinder range extender specially built for the range extension system. It runs very smoothly, and the maximum power generation efficiency can reach 3.2 kW h/L under the action of 41% ultra-high thermal efficiency. In terms of cruising range, the pure battery life of AITO-bound M5 under WLTC condition is 150km. Under the condition of full charge and full oil, the comprehensive battery life under WLTC condition is over 1,100 km, which is superior to all pure electric vehicles. At the same time, the fuel-and-electricity charging method can better meet the needs of users in complex usage scenarios.

Li ONE also uses the extended range platform, but the specifications and structure of the range extender are different from those of AITO M5. It uses a 1.2T three-cylinder range extender. Although the dynamic parameters are good, the inherent structure of the three cylinders is not good for the ride comfort, thus affecting the NVH performance of the whole vehicle. In terms of cruising range, Li ONE’s WLTC has a comprehensive cruising range of 890km, which is far ahead of most pure electric vehicles, although it is far from AITO’s M5, and there is no mileage anxiety.

Power system comparison: all adopt dual-motor four-wheel drive, and AITO asks M5 to accelerate faster.

AITO Interface M5 adopts a dual-motor four-wheel drive scheme, the front axle is equipped with asynchronous AC motor and the rear axle is equipped with permanent magnet synchronous motor. This combination achieves a balance between performance and energy consumption. Under the strong power output, the zero-speed acceleration time of AITO’s flagship version of M5 four-wheel drive reached 4.4 seconds, which led a number of new energy vehicles.

Li ONE also adopts the dual-motor four-wheel drive scheme, but both motors are permanent magnet synchronous motors, with the maximum power of 245kW and the maximum torque of 455N·m, which is not as radical as AITO’s M5, and the acceleration time is 6.5 seconds, which is nearly 2 seconds behind AITO’s M5. This result is also expected. After all, Li ONE is positioned as a medium-and large-sized SUV for home use, which is more suitable for the daddy crowd. Even so, the acceleration performance of Li ONE is compared with that of gasoline at the same price and the same level.

Chassis specification comparison: the lightweight of AITO interface M5 is more in place, and the front suspension is higher.

As a high-end SUV, AITO Wujie M5 adopts an all-aluminum chassis, which is not only lighter but also better in rigidity and strength than the traditional steel chassis. In terms of suspension, AITO M5 also shows sincerity. The front suspension is a double wishbone structure exclusive to luxury cars, which can better restrain the roll and control the corners steadily. The rear suspension is a multi-link structure, which has good shock absorption, can absorb the vibration caused by uneven roads and improve the ride comfort.

Li ONE is a little more expensive than AITO M5, but the chassis material is not as kind as AITO M5. Although there are some aluminum alloy components, the application scope is not wide enough. In terms of suspension, Li ONE’s front suspension is a common McPherson style, which is simple in structure, small in size and more easily accepted by manufacturers. However, the curve limit is not as high as that of the double wishbone, and the rear suspension is also a multi-link structure, so the comfort is guaranteed.

As two representative players in the field of extended-range electric vehicles, both the M5 and Li ONE of AITO have good comprehensive strength, which meets the diversified car demand of users. In terms of the comprehensive cruising range, acceleration performance and chassis specifications, the performance of AITO Jiejie M5 is even better. Considering that its price is also lower than that of Li ONE, AITO Jiejie M5 is more worthy of consumers’ choice based on the car purchase concept of "spending less money to buy a better experience".
