Following Shanghai and Beijing, Guangzhou, a first-tier city, has also implemented the provident fund policy of "recognizing housing but not loans". In addition, compared with Beijing and Shanghai, Guangzhou’s policy went further. For the first home, the minimum down payment ratio was reduced from 30% to 20%.

　　On November 14th, Guangzhou Housing Provident Fund Management Center issued the Notice on Optimizing Personal Housing Provident Fund Loans (hereinafter referred to as the Notice). The "Notice" mentioned that the number of housing units under the family name is accounted for by the "Guangzhou Natural Person Real Estate (Land, Housing) Information Query Results" provided by the Guangzhou Real Estate Registration Agency. In other words, families without housing who have had a loan or purchase record before can now buy a house for the first time and enjoy a preferential down payment ratio for the first time. For example, for families with "sell one and buy one" replacement needs, they can already enjoy the low down payment ratio discount for the first purchase through provident fund loans when replacing houses.

　　The "Notice" clarifies that the minimum down payment ratio of provident fund loans is 20% (originally 30%) for buyers who purchase the first home in Guangzhou; The minimum down payment ratio of provident fund loans is 30% for the families of buyers who have no housing loans (including commercial housing loans and provident fund loans, the same below) or whose housing loan records have been settled and own a house in Guangzhou; The minimum down payment ratio of provident fund loans is 40% for the families of buyers who have outstanding housing loan records and own one house in Guangzhou. The Notice shall come into force as of the date of issuance and shall be valid for 5 years.

　　In addition, the official has also interpreted the contents of the Notice: the number of housing units under the family name is only calculated in Guangzhou, but not in other places; The nationwide housing loan records (whether settled or not) no longer affect the identification of housing units; Those who buy the third and above houses in Guangzhou will not be granted housing provident fund loans; When calculating the number of housing units under the family name, the houses that have been sold and are no longer under the family name are not included; There is no difference in the minimum down payment ratio between ordinary housing and non-ordinary housing, and the same minimum down payment ratio applies; For the housing provident fund loans being handled, if the housing provident fund loans have not been mortgaged, you can apply to the original loan handling outlets according to the "Notice" policy, modify the information or cancel the loans and re-apply.

　　Yan Yuejin, research director of Yiju Research Institute, said that "admitting housing but not lending" was mainly reflected in housing commercial loans. After the promulgation of this policy, "admitting housing but not lending" has covered the field of provident fund loans, which will help to release the demand for improved housing.

　　Since the introduction of the new real estate policy in late August and mid-September, the transaction area of commercial housing in Guangzhou has obviously rebounded. According to the data of the Central Finger Research Institute, in October 2023, the transaction area of new houses in Guangzhou was about 712,000 ㎡, up by 35.2% year-on-year. However, in November, the policy influence began to weaken, and the market enthusiasm of new houses decreased. The transaction area of new houses in Zhou Du has been declining for two consecutive weeks.

　　Yang Hongxia, general manager of the South China Branch of the Central Finger Research Institute, said that the release of the new provident fund loan policy in Guangzhou will further promote the market rigidity and the effective release of improved demand. The introduction of the new policy of Guangzhou provident fund will release a positive signal to the market, which will help stabilize market expectations, boost the sentiment of buyers and promote the stable and healthy development of Guangzhou real estate market.

　　"The decline in real estate sales and the payment of employee provident fund as usual have led to a relatively high water level in the provident fund pool. From the perspective of policy formulation, it is inevitable to consider how to make better use of this part of inefficient or even idle funds." Li Yujia, a researcher at the Guangdong Housing Policy Research Center, said that the low interest rate of provident fund loans can stimulate the enthusiasm of buying houses, and the implementation of the optimization policy of provident fund loans is a general trend.

　　In contrast, Guangzhou Provident Fund has taken a bigger step than commercial loans in the implementation of the policy of "recognizing houses but not loans", because at present, the down payment ratio of the first commercial housing loan in Guangzhou generally needs 30%, and only a few banks can 20%; For families who already own a house and buy a house again, the down payment for commercial loans needs 40%. "Because local governments have greater autonomy in the provident fund policy." Li Yujia said.

　　At the same time, Li Yujia said that it is necessary to look at the effects of the above policies objectively. "Some demand will be released, but the scale of this demand is not particularly large." Li Yujia believes that whether the new Guangzhou provident fund loan policy can play a greater role in the property market depends on whether the paid employees can get enough loans. In the case of limited personal and family loans (the maximum personal loan is 600,000 yuan and the maximum family loan is 1 million yuan), the high probability of buying a house in Guangzhou still needs to take the form of "provident fund+business" combined loan, and the effect of the policy may not be so high. In addition, most of the people who can get such a high loan amount are staff in the system or employees of state-owned enterprises and institutions. Most of these people have already bought houses (mainly new employees will release some demand), but those who really need provident fund, low-interest loans are mainly new citizens, young people and migrants, but these people have a small deposit balance and a low deposit ratio, so it is difficult to get full loans.

　　Compared with the down payment ratio of commercial loans, the current down payment ratio of Guangzhou provident fund loans is relatively low. It is not clear whether the down payment ratio of portfolio loans is implemented according to the standards stipulated by provident fund loans or commercial loans. A real estate agent told CBN that it depends on how the bank implements it, and it will only be known after consulting the housing provident fund center. In addition, some real estate agents said that portfolio loans should be implemented in accordance with the standards of commercial loans, and the down payment of 20% needs pure provident fund loans to be implemented.

　　Because the loan amount of many houses in Guangzhou will exceed the maximum amount of provident fund loans, it is necessary to adopt combined loans. Some real estate agents said that if the down payment ratio is implemented according to the standards of commercial loans, this policy will not have much impact on real estate transactions with mortgage loans exceeding 1 million yuan, and it will not have much impact on the property market.

　　In addition, according to the statistics of the Central Finger Research Institute, as of November 13th, more than 250 policies related to provident fund have been issued in various places this year, and more than 30 cities have optimized the standard of "recognizing housing and repaying loans" for provident fund loans, among which more than 20 cities have implemented "recognizing housing but not repaying loans" for provident fund loans (including Shanghai and Beijing), and reduced the down payment ratio of provident fund loans in many places.

　　Cctv news: Chang ‘an Street in Beijing, known as "the first street in China", on the eve of the "Belt and Road" international cooperation summit forum, the CCTV aerial report team used drones to have a bird’s eye view of Chang ‘an Street in the air, and felt that history and modernity complemented each other here.

　　The eastern section of Chang ‘an Avenue, a piece of beijing central business district, is the headquarters of many Fortune 500 companies in China, the cradle of numerous small and medium-sized enterprises’ entrepreneurship and growth, and the vibrant area of Beijing.

　　Chang ‘an Avenue is north of guomao bridge. Now you can see the Chinese statue under construction, which will become the tallest landmark building in Beijing after completion. At present, its building height has exceeded 500 meters.

　　Adjacent to China Zun is the Guanghua Road office area of CCTV. On May 14th and 15th, when the "Belt and Road" international cooperation summit forum is held, all the live broadcast signals from the venue will gather here, and then CCTV channels will report the grand event for the first time.

　　From east to west, follow our lens, and now we come to Jianguomen overpass on Chang ‘an Avenue, which connects Beijing’s Second Ring Road. The traffic is busy, and there is an ancient city wall in the southwest corner of the overpass, which is the ancient observatory of Beijing. It is one of the oldest observatories in the world, which was founded in the Ming Dynasty. These eight astronomical instruments not only have the traditional characteristics of China in modeling and ornamentation, but also reflect the progress and achievements of western astronomical instruments after the Renaissance in terms of scale and structure. This is an example of cultural exchange between the East and the West.

　　Chang ‘an Street has witnessed the passage of time and historical changes. The Beijing Telegraph Building, located at No.11 West Chang ‘an Avenue, was once the first new telegraph building in New China. Until today, its bell will still ring when it strikes the hour. People used to send and receive telegrams and make long-distance calls here. However, with the development of communication, it is now possible to connect with the world by a mobile phone without leaving home. The telegraph building has become a historical witness of the rapid development of communication in China.

In case of particularly serious public health emergencies or other emergencies that seriously threaten public health in domestic emergency use, it can be used for emergency use within a certain scope and time limit with the consent of the drug supervision and administration department of the State Council.

Second, COVID-19 vaccine which effect is better?

1. Beijing Biological COVID-19 Vaccine

The WHO Advisory Expert Group on Immunization Strategy has completed the review of the vaccine. A large multinational phase III clinical trial showed that the effective rate of preventing symptomatic Covid-19 infection 14 days or longer after vaccination was 79%, and the effective rate of preventing hospitalization was 79%. Because there are very few elderly people over 60 who participate in clinical trials, it is impossible to estimate the effectiveness of this age group; Despite this, WHO does not recommend setting an upper age limit for the vaccine, because preliminary data and immunogenicity auxiliary data indicate that the vaccine may also have a protective effect on the elderly.

2. Kexing Zhongxin Crown Vaccine

The WHO Advisory Expert Group on Immunization Strategy has completed the review of the vaccine. The results of vaccine efficacy research show that the vaccine can prevent 51% of the vaccinated people from developing disease symptoms, and prevent 100% of the research population from developing severe Covid-19’s disease and hospitalization. Because there are very few elderly people over 60 who participate in clinical trials, it is impossible to estimate the effectiveness of this age group; Nevertheless, WHO does not recommend setting an upper age limit for the vaccine, because the data and immunogenicity auxiliary data collected during the subsequent use in many countries indicate that the vaccine may also have a protective effect on the elderly.

3. Wuhan Biological COVID-19 Vaccine

The interim analysis data of the international multi-center, randomized, double-blind, placebo-controlled phase III clinical trial in the United Arab Emirates and other countries showed that the protection rate of the vaccine against the diagnosed moderate and severe diseases reached 100%, and the total protection efficacy was 72.51%. The vaccine is currently awaiting approval from WHO.

4. Kangxinuo COVID-19 vaccine

The data of Phase III clinical trials of more than 40,000 subjects in 78 clinical research centers in five countries (Mexican, Russian, Pakistani, Argentine and Chilean) showed that the protective effect of the vaccine on severe COVID-19 was 90.98% after 28 days of single-needle vaccination, and the overall protective effect was 65.7%. The vaccine is currently awaiting approval from WHO.

5. Zhifei COVID-19 vaccine

The results of two clinical trials involving 950 healthy adults aged 18-59 in Chongqing, Beijing and Hunan provinces in China showed that 76% and 97% of people could produce neutralizing antibodies after two doses and three doses of vaccine respectively. At present, no phase III clinical trial data has been published.

6. Kangtai COVID-19 vaccine

Phase II clinical trials showed that the median GMT of live virus neutralizing antibody in the vaccine group was 131.7 IU/ml 28 days after the 18-59-year-old subjects completed the whole immunization, which indicated that the vaccine could induce a strong antibody response in adults aged 18-59. At present, no phase III clinical trial data has been published.

7. COVID-19 vaccine of Institute of Biology, Chinese Academy of Medical Sciences.

The results of phase ⅰ and ⅱ clinical trials showed that the positive conversion rates of neutralizing antibody and anti-S protein antibody reached 96% and 99.33% respectively 14 days after the whole vaccination. At present, no phase III clinical trial data has been published.

To sum up, every COVID-19 vaccine brand is good and has its own characteristics.

Generally speaking, at present, there are seven COVID-19 vaccines approved by the state in China, each of which has its advantages. Therefore, it is ok to fight any one, and there is no need to wait for any brand of vaccine.

On May 10th, the 8th China Brand Day, a series of activities of 2024 China Brand Day-"Super Convergence is Super Hybrid" DMH technology brands Conference, sponsored by Xinhua News Agency Shanghai Branch and China Economic Information Agency, and jointly sponsored by SAIC Innovation Research and Development Institute and Roewe brand of SAIC passenger cars, was held in Shanghai. Jiang Wei, Party Secretary of Xinhua News Agency Shanghai Branch, Party Secretary of China Economic Information Agency Shanghai Headquarters, Zu Sijie, Vice President and Chief Engineer of SAIC, Alvin Wong, General Manager of SAIC Passenger Car Company, Lian Ping, Chairman of China Chief Economist Forum, Yao Chunde, Professor of Tianjin University and Deputy Director of "China Heart" Top Ten Engine Judges, and other guests attended the meeting to discuss the new breakthrough of hybrid technology in China and how to accelerate the cultivation of new quality productivity in new energy automobile industry.

At the meeting, SAIC Roewe released the "DMH Super Hybrid Technology" technology brands, which has accumulated the profound technology of SAIC in the hybrid field for more than ten years. It is a hybrid product for users all over the world, showing the world the vigorous power of China automobile brands in the new energy era.

Blending is an indispensable starting point for the transformation of automobile industry chain.

By the end of 2023, the production and sales of new energy vehicles in China ranked first in the world for nine consecutive years, and became the world’s largest automobile exporter for the first time. Under the wave of new energy, whether from the perspective of solving the pain points of users’ actual car use or from the height of the transformation and upgrading of the entire automobile industry chain, blending is an indispensable key. Yao Chunde believes that the development of hybrid technology is the general trend.

Yao Chunde, a professor at Tianjin University and deputy director of the "China Heart" Top Ten Engine Judges.

On the one hand, there is a strong user demand to promote the hybrid technology in China. The market environment and users’ demand in China provide a natural "fertile ground" for car companies to develop hybrid technology. On the other hand, the breakthrough of China car companies in the plug-in technology is not to show off their skills, but based on real usage scenarios, which integrates the advantages of traditional fuel vehicles and electric vehicles and brings users real travel solutions. Taking the DMH super hybrid system as an example, Yao Chunde innovatively improved the off-axis P1 motor into a coaxial structure for the current mainstream P1+P3 hybrid configuration, which greatly improved the transmission efficiency, optimized the NVH performance, and made the whole system more efficient and the driving experience smoother and quieter. It can be seen that the plug-in technology is not a transitional technology, but a key technology to drive the traditional automobile to realize electric transformation and comprehensively improve the user’s travel experience, and it is also an indispensable technical support for China automobile to "grow from big to strong".

Roewe DMH: Super fusion is super hybrid.

"At the moment, hybrid technologies are blooming, products are emerging one after another, and user acceptance is getting higher and higher. It is predicted that by 2025, there will be a 1:1 situation between pure electricity and plug-in. The spring of plug-in and hybrid is already around us. " Lu Yong, deputy general manager of SAIC Passenger Car Company, executive vice president of SAIC Innovation Research and Development Institute and executive deputy director of technology center, said.

Lu Yong, Deputy General Manager of SAIC Passenger Car Company, Executive Vice President of SAIC Innovation Research and Development Institute and Executive Deputy Director of Technology Center.

The greatest advantage of any technology with long-term value is that it can withstand precipitation and carry long-term optimization iteration. As early as 2010, SAIC proactively laid out the field of plug-in hybrid technology and regarded it as a technology worthy of long-term investment. In 2017, the first generation of EDU hybrid technology independently developed by SAIC won the second prize of the National Science and Technology Progress Award. Thanks to SAIC’s in-depth self-research on the core technology of powertrain, SAIC will also exceed 46% in the key index of engine thermal efficiency that affects the performance of hybrid system. After long-term technical accumulation and market verification, the DMH super hybrid technology released at this conference, with by going up one flight of stairs integration and intelligence, is a new kinetic energy for SAIC’s own brand to maintain its long-term competitiveness.

DMH super hybrid technology has three technical characteristics: modularization, integration and specialization. According to the modular design and serial configuration, the system matches different hybrid routes such as PHEV/EREV/HEV through a set of systems, which can cover the driving needs and fuel consumption regulations of different users around the world. At the same time, the system has many leading technologies such as "energy domain" global thermal management, powertrain brain PICU, engine +P1 motor coaxial structure, etc., with software algorithm as the core, matching special hardware such as hybrid high-efficiency engine, gearbox and long-life battery.

At present, DMH super hybrid technology has taken the lead in the Roewe D7 DMH and the Roewe D5X DMH, the new mainstream hybrid SUV with long battery life, and the product strength has been widely recognized. Not long ago, Roewe D7 DMH, on behalf of its own brand B-class car, challenged the extreme endurance of 2,000 km, and finally overcame the influence of bad weather, achieving a long endurance of 1962km and an average fuel consumption of 2.8L per 100 km, realizing the technical value transformation from technical strength to scene application, and showing the strength of China brand.

Qiu Jie, Vice President of SAIC Innovation Research and Development Institute and General Manager of Jieneng Automobile Company.

Qiu Jie, vice president of Innovation Research and Development Institute of SAIC and general manager of Jieneng Automobile Company, said that in the next three years, DMH super hybrid technology brands will carry out higher-dimensional performance improvement in five key areas: engine, gearbox, battery, motor and energy control brain. For example, the thermal efficiency of the engine will break through to 46%, and it will take the lead in reaching the "Euro 7" emission standard in China; In terms of gearbox technology, the target carbon dioxide emission of the oil-electric hybrid route will not exceed 95g/km, and the plug-in hybrid and extended-range electric routes will adopt a new configuration of dual coaxial scheme; The energy control brain is continuously optimized, and the concept of the next generation vehicle energy center is expected to be released in 2025.

Start SAIC brand

With the joint efforts of the upstream and downstream of the industrial chain, automobiles have become a shining business card for China brands to go global. Among them, SAIC has won the "Double Champion" in domestic sales and vehicle export for eight consecutive years, and has become an excellent sample for actively practicing the "three transformations" in brand building.

Zu Sijie said at the conference: "Brand building is an important support for further developing China’s intelligent networked new energy automobile industry. At present, SAIC is building a world-class enterprise by benchmarking, making every effort to build itself into a trillion-dollar automobile industry group with global industrial competitiveness and brand international influence, and constantly making SAIC brand famous by building technology SAIC, quality SAIC and responsibility SAIC. The launch of DMH super hybrid technology is the’ super integration’ of technology SAIC, quality SAIC and responsibility SAIC, and it is also an important practice to start the SAIC brand. "

Zu Sijie, Vice President and Chief Engineer of SAIC.

SAIC has always adhered to technological innovation as the core drive, accurately grasped the market development trend, and actively laid out forward-looking technical fields. After long-term unremitting investment and deep cultivation, the "turn" from technology introduction to technology reverse output has been basically completed. Facing the new round of global competition, SAIC Innovation Research and Development Institute, the research and development platform of SAIC’s own brand of passenger cars, has made full preparations in the fields of forward-looking technology, R&D personnel, hardware and equipment, and effectively supported the product development of Roewe, MG, Zhiji and Feifan and overseas markets.

In terms of talent reserve, SAIC Innovation Research and Development Institute is committed to building a research and development team with global vision and competitiveness. Not long ago, Joseph Kaban, a world-renowned automobile designer, officially joined SAIC, which will further promote SAIC’s design upgrade, vigorously enhance the competitiveness and internationalization level of SAIC’s design, and empower its own brands such as Roewe.

The release of DMH Super Hybrid technology brands indicates that SAIC Roewe will launch the quality war and value war of its own brand "National Team" in the new energy market with more confident brand image and stronger product competitiveness, and help the high-quality development of China’s new energy automobile industry. In the future, relying on DMH super hybrid technology brands, Roewe will also gather the superior resources of all parties, accelerate the creation of "the first camp of blending", and provide users around the world with a new choice of China brand.

　　(Reporter Ping Liu Meng Ruobing) On the 3rd, Wang Changsong, Chairman of the CPPCC, led some CPPCC members to Tianjin University to conduct research on accelerating scientific and technological innovation to drive Tianjin’s high-quality development.

Kaiyi Xuanjie uses a 1.5-liter naturally aspirated four-cylinder engine, which has excellent performance. As a compact SUV, Kaiyi Xuanjie has a length, width and height of 4,400 mm, 1,831 mm and 1,653 mm respectively, and a wheelbase of 2,632 mm. This model has a five-door and five-seat design and is very practical.

Kaiyi Xuanjie’s 1.5-liter naturally aspirated engine has a maximum power of 85kw, a maximum power speed of 6,150 rpm, a maximum torque of 143 Nm and a maximum torque speed of 4,000 rpm. This engine adopts multipoint injection technology, and is equipped with aluminum alloy cylinder head and cast iron cylinder block, which can improve the reliability and durability of the engine, because it can withstand higher temperatures and pressures.

This engine of Kaiyi Xuanjie is matched with a 5-speed manual gearbox or CVT gearbox. Using CVT gearbox can improve the shift smoothness and fuel economy of the car, because its internal structure is relatively simple, with only two bevel wheels and a steel chain. The steel chain can move on the bevel wheel to realize the function of speed change and torsion change. In addition, the cost of CVT gearbox is relatively low, which helps to reduce the price of the car.

The front suspension of Kaiyi Xuanjie adopts McPherson independent suspension, while the rear suspension adopts torsion beam non-independent suspension. The use of torsion beam can expand the rear seat space and trunk space, and improve the practicability of the vehicle.

CCTV News:On March 15th, the National Health and Wellness Commission and state administration of traditional chinese medicine issued the "novel coronavirus Diagnosis and Treatment Plan (Trial Ninth Edition)". The new diagnosis and treatment plan has made many major updates in detection, management and treatment, optimized the procedure of case discovery and reporting, and added antigen detection as a supplement to further improve the ability of case early detection. At the same time, the cases were classified and treated, and the light cases were changed from being admitted to hospitals to centralized isolation management.

The diagnosis and treatment plan further improves the measures of case classification and treatment

In the case treatment, the new diagnosis and treatment plan further improved the case classification treatment measures according to the opinions reflected by various places, such as "asymptomatic infected patients and mild cases are the main patients in Omicron, and most of them don’t need too much treatment, and all of them will occupy a lot of medical resources when they are admitted to designated hospitals".

Light cases changed from income hospital to centralized isolation management.

For the confirmed cases, the new version re-classifies them into light, ordinary, heavy and critical types. Light cases are subject to centralized isolation management, and relevant centralized isolation places cannot isolate people such as entry personnel and close contacts at the same time. During the period of isolation management, symptomatic treatment and condition monitoring should be done well. If the condition worsens, it should be transferred to a designated hospital for treatment.

At present, asymptomatic and mild cases account for the majority, and the new version of the diagnosis and treatment plan is expected to reduce the burden of treatment for designated hospitals and medical staff, reduce the risk of medical resources run, and achieve more accurate management. In addition, ordinary, severe and critical cases and cases with severe high-risk factors should be treated in designated hospitals, and severe and critical cases should be admitted to ICU as soon as possible.

Two new specific anti-Covid-19 drugs were added.

In terms of specific drug treatment, the new diagnosis and treatment plan has added two COVID-19 antiviral drugs newly approved by National Medical Products Administration..Revise and improve the content of TCM treatment. Combined with the clinical treatment experience in various places, the application of non-drug therapy in traditional Chinese medicine was strengthened and the content of acupuncture treatment was increased; Combined with the characteristics of children patients, the related contents of traditional Chinese medicine treatment for children were added.

The plan also adjusts the management of release from isolation, discharge standards, release from isolation and matters needing attention after discharge. For example, the "14-day isolation management and health monitoring after discharge" was changed to "release isolation management or continue home health monitoring for 7 days after discharge".

On the basis of nucleic acid, antigen detection is added as a supplement

The plan proposes to add antigen detection as a supplement on the basis of nucleic acid detection to further improve the ability of early detection of cases. The relevant person in charge of the National Health and Wellness Commission stressed that the antigen positive must be linked to the nucleic acid detection in a closed loop, and the antigen positive result can be used for early triage and rapid management of suspected people, and cannot replace the nucleic acid detection to determine whether the detected person is infected with COVID-19.

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:The specificity of antigen detection can reach 99%, but the specificity of nucleic acid detection in methodology is 100%, so nucleic acid detection has always been a basis and a "gold standard" for determining COVID-19 infection, so antigen detection cannot replace nucleic acid detection. When the antigen test is positive, you must take the nucleic acid test to confirm it; But the nucleic acid test is positive. No matter whether your antigen test is negative or positive, the examinee should take measures as an infected person or a confirmed patient in COVID-19.
