Since the outbreak of COVID-19 last year, the topic of high false negative rate of nucleic acid detection has been the focus of attention. It has been reported that the positive rate of Covid-19 detection by fluorescence quantitative RT-PCR is only 30%-50% at present, which leads to extremely high false negative rate.

For Hongge, who doesn’t know much about the test, this paper analyzes the relatively high false negative test by searching articles and documents, and summarizes some reasons to discuss with you.

First, the incidence of COVID-19 suggests that it is highly possible to collect positive samples in a proper time.

Academician Yuan Guoyong’s team conducted this cohort study in Hong Kong Princess Margaret Hospital and Queen Mary Hospital. From January 22 to February 12, 2020, 23 hospitalized patients who were diagnosed as COVID-19 by laboratory examination of nasopharyngeal or sputum specimens were screened in the two hospitals.

A total of 173 respiratory specimens were collected from 23 patients. The researchers used RT-QCPR to determine the viral load in the samples. The results showed that the median viral load of respiratory tract samples was 5.2 log10 copies /mL (interquartile range was 4.1-7.0), and only 3 patients (13%) did not detect Covid-19 RNA in saliva samples.

The researchers observed that,The viral load in saliva was the highest in the first week after the patient developed symptoms, and then gradually decreased.Eight days after the patient developed symptoms, airway extracts were collected, and there was no obvious downward trend in viral load. Of the 21 patients who did not die,Seven people (33%) could still detect viral RNA after 20 days of symptoms, but this was not related to the severity of the disease.

▲ Changes of viral load in saliva (blue line) and airway extract (red line) of all 23 patients. Abscissa D- days after symptoms appear; S/E- number of saliva/airway samples.

AprilAccording to a study published in Nature Medicine, COVID-19 patients are most infectious before symptoms appear, and they begin to shed SARS-CoV-2 2 2-3 days before the first symptoms appear.

https://doi.org/10.1038/s41591-020-0869-5

The study, led by Eric Lau of the University of Hong Kong, involved 94 patients with COVID-19 admitted to the Eighth People’s Hospital of Guangzhou, China, 50% of whom were male, with a median age of 47 years. Among them, 61 of 93 patients were mild. Specifically, the researchers collected the throat swabs of 94 COVID-19 patients who were treated in the Eighth People’s Hospital of Guangzhou, China from January 21st to February 14th. From the onset of symptoms to 23 days after onset, 414 throat swabs were collected.

The results show that the researchers areThe high viral load was detected shortly after the patient developed symptoms, and then gradually decreased to the detection limit around the 21st day.There is no significant difference in viral load among different sexes, age groups and disease severity.

In addition, the researchers also analyzed 77 samples of "transmission pairs" from public data to assess how much time passed between the onset of symptoms in each patient. It assumes that the median incubation period (the time from infection to symptoms) is 5.2 days.The research team concluded that infectivity began 2.3 days before symptoms appeared, and peaked 0.7 days before symptoms appeared.

In the sensitivity analysis, the same estimation procedure is used, but assuming that the infectious attack is unchanged 1-7 days before the symptom occurs, thenIt was found that the infectivity reached its peak 0-2 days before the onset of symptoms, and the transmission ratio before the onset of symptoms was 46% to 55%.

The study also found that,The virus may start shedding 2-3 days before the first symptoms appear.After the symptoms appear, the viral load in the patient’s body decreases faster. This is consistent with the results of two recent studies. On April 1st, teams from Munich, Germany, Berlin and Cambridge, England published the article "Viro logical assessment of hospital patients with Covid-2019" on Nature. It was found that the shedding peak of Covid-19 occurred in the early upper respiratory tract infection.This shows that virus carriers may be the most infectious when they have mild symptoms or almost no obvious symptoms.

Brother Hong:From the above two documents, we can draw a conclusion that the virus shed and spread 2-3 days before the symptoms appear after infection, and after the symptoms appear, with the passage of time,The viral load of throat swab decreases gradually, and the viral load detected within 7 days after symptoms. If symptoms have existed for more than 20 days, the reliability of negative conclusion of throat swab is poor.

Solution:We need to publicize the law of the new crown to the people and medical workers, and improve our vigilance against COVID-19. It is best for patients to see a doctor in time, and doctors can also suspect this possibility. Only at the right time can we collect high-content samples and diagnose and control them in time.

Second, accurate sampling strategy is the best means to reduce false negative results.

In February, a study published by Medrxir, a pre-printed website, collected respiratory tract samples such as nasal swab, throat swab, sputum and bronchoalveolar lavage fluid (BALF) from patients diagnosed with COVID-19, and included 213 Covid-19-infected patients admitted to the Third People’s Hospital of Shenzhen from January 11th to February 3rd, 2020, who were diagnosed by Guangdong CDC. A total of 866 respiratory tract samples, including 490 nasal swabs, 205 throat swabs, 142 sputum samples and 29 BALF samples, were collected at the time of admission and after each time point. According to the collection date, the samples were divided into 0~7 days, 8~14 days and ≥15 days after onset. According to the guidelines on prevention and treatment of Covid-19 infection issued by National Health Commission, patients were divided into severe and mild cases.

Three groups were divided according to the sample collection time after onset, and the viral nucleic acid was quantitatively determined.The positive rate of viral nucleic acid in sputum samples was the highest in the group of 0~7 days after onset.The positive rates of severe and mild cases were 88.9% and 82.2% respectively.Followed by a nasal swab.(73.3% and 72.1% respectively),The throat swab again.(60.0% and 61.3% respectively). In mild cases, the positive rate of nasal swab and sputum samples is similar.

The positive rate of BLAF samples collected from 8 to 14 days after the onset of severe cases was 100%.However, the BALF samples of 3 mild cases were negative. In all cases, the positive rate of sputum samples was the highest in the 8~14 days after onset, which was much higher than that of nasal swab and throat swab. It is worth noting that the positive rate of throat swab in severe patients is only 50%, and that in mild patients is only 29.6%.

In the group ≥15 days after onset,The positive rates of BALF, sputum and nasal swab from severe cases were similar. In mild cases, the positive rate of sputum and nasal swab is similar, which is much higher than that of throat swab.

For the diagnosis of viral nucleic acid in COVID-19’s patients,Sputum samples are the most accurate, followed by nasal swabs. It is not recommended to collect throat swabs for diagnosis.

The difference between oropharyngeal swab and nasopharyngeal swab

anusswab

Brother Hong:

1. Oropharyngeal swab is the least painful and most acceptable, but it has to bear the consequences of high false negative results. My suggestion is to use it according to the epidemic risk in the first epidemic area.

2. The positive rate of nasopharyngeal swab is higher than that of oropharyngeal swab, which is why nasopharyngeal swab is introduced into laboratory examination in the fifth edition of Diagnosis and Treatment Plan for Pneumonia Infected by Covid-19 (the fourth edition is still pharyngeal swab). If we want to pursue accuracy, it is suggested to use it, or to use it when screening people in close contact or sub-close contact. At present, the examination of returnees in domestic reports seems to be nasopharyngeal swab method.

3. Alveolar lavage fluid can’t be used for screening in the general population, so it is suggested that hospitals with ICU should use it for screening severe pneumonia patients living in ICU for COVID-19 patients.

4. Deep expectoration seems to be the best sample, but many patients in COVID-19 have a dry cough, which may not be possible.

5、anusSwabs were used in Daxing epidemic in Beijing, which is the first time to use this method in the screening process. In some literatures,anusAlthough the positive rate of swabs is not high, as I remember, it seems to be more than 10%, but it does not seem to coincide with the patients with oropharyngeal swabs, suggesting that the virus may attack the gastrointestinal tract, and also suggesting that there may be the possibility of gastrointestinal transmission in Covid-19. Although the initial symptoms of some patients are gastrointestinal symptoms such as abdominal pain and diarrhea, there are also ACE2 receptors in the digestive tract, which is theoretically possible, but it has not been confirmed at present. So,anusMy suggestion is that swabs can only be used as a supplement to nasopharyngeal swabs, and it is better to select patients whose first symptoms are digestive tract symptoms more accurately, which is unlikely to be used as a means of large-scale screening.

Solution:It is best for National Health Commission to issue a guiding document for large-scale screening, and make detailed regulations on what population and what sampling methods to adopt under what circumstances.,When local governments encounter an outbreak in COVID-19, it’s best to ask professionals to act as consultants and make choices according to the actual situation.

Third, the consistency of sampling ability of sampling personnel affects the sampling results.

Garbage in, garbage out (garbage samples produce garbage results), which is a sentence that inspectors often say.

The sampling team is huge, and the ability of sampling personnel must be uneven. In addition, people may have such fears about sampling, which often leads to unqualified samples.

Generally, there is an internal standard in the molecular diagnostic reagent to monitor the detection process, for example, RNaseP is used as the internal standard. If both the sample response curve and the internal standard response curve displayed by the fluorescence PCR platform do not jump, it means that the quality of the collected samples may have problems or false negatives may occur due to improper experimental operation, which needs to attract the attention of medical workers. The RNaseP internal standard can monitor the sample collection and ensure the accuracy of the test results.

Note: RNaseP is ribonuclease P, which is one of the most important ribozymes in human body. It is ubiquitous in all organs, tissues and cells of human body, and can detect RNA nucleic acid fragments from human body samples, and can also be used as an internal standard.

And I privately asked the relevant person in charge of our city’s temporary inspection center. He told me that every day in our hospital, some samples were told that they needed to be re-sampled because the internal standard did not jump. Imagine that you didn’t wipe down a few cells in your throat swab collection, so will the negative of this nucleic acid be accurate?

Solution:Consistency training for nucleic acid sampling personnel will greatly reduce the human influence, and it is easier to standardize the sampling process by taking such sampling methods as nasopharyngeal swab. Our city seems to have trained the nucleic acid emergency sampling team very early. What about your city?

In addition, if in the environment of large-scale nucleic acid sampling, when testing under the standard of 5-mixed 1 and 10-mixed 1, according to the above principle of internal standard, it seems that there is no single-tube ability in the quality control of internal standard. Therefore, especially those in the emergency sampling team, we must pay attention to the standard sampling methods and remember to collect qualified samples as much as possible.

Fourth, choose the right oneSampling device

The virus preservation tube mainly consists of a sampling swab and a virus nucleic acid preservation tube (containing virus nucleic acid preservation solution). There are many kinds of virus preservation tubes on the market at present.It is very important for epidemic prevention and disease diagnosis to choose the appropriate virus preservation tube, reduce the infection risk of medical inspectors as much as possible, and keep the virus RNA stable without degradation..

The preservation solution UTM used in traditional virus collection tubes is based on Hank’s solution, with gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids added. Its main purpose is to maintain the virus activity within a certain temperature range, so that it is convenient for health and epidemic prevention departments to further isolate, culture and trace the virus and determine the pathogen. This kind of non-inactivated tube, which I call it, is good for further work, but the sameLive virus increases the infection risk of medical staff in the whole process of sample collection, transportation and testing!Personally, I think this kind of sampling tube for inactivated virus should be a better choice for disease control sampling.

And clinicalIn order to achieve the purpose of rapid detection, it is not necessary to cultivate the virus, but only to crack the virus, so as long as the integrity and stability of the virus nucleic acid can be guaranteed.nowCommonly known as inactivation tube.Many inactivation tubes in China are used.The inactivation component is guanidine salt, which is in this inactivation tube in our hospital.Guanidine salt can crack the virus, but it can’t protect the integrity of nucleic acid for a long time.The virus nucleic acid may have been degraded during the delivery of the sample to the laboratory, which will also cause a "false negative" in the detection. Many studies show that both temperature and time can affect the test results, so the COVID-19 Laboratory Testing Guide has clear requirements for samples to be tested within 24 hours after collection and transported at 4 degrees Celsius. If it is necessary to exceed 24 hours, it should be stored at -70 degrees Celsius.

And some manufacturers put forward another inactivation tube, a kind of.containNon-guanidine saltThe virus preservation tube containing protein denaturant can inactivate the virus and ensure the preservation of virus nucleic acid at room temperature.And the virus nucleic acid is stably stored for 7 days.Does not degrade.

Solution:

1, from sampling to testing, it is necessary to mark the time, so that quality control can be carried out on the preservation time, which is basically no problem in a better hospital.

2. For the front-line staff to do the corresponding training, they should know the advantages and disadvantages of various types of preservation tubes and adopt the best sampling tubes suitable for local conditions.

3. It is best for the country to recommend the selection of sampling tubes with the support of relevant experimental data.

5. Failure of reagents caused by virus mutation?

After the virus mutation in South Africa, Britain, Brazil and other places, there have been cases that turned positive after ten tests in various parts of the world, including China.The FDA recently warned that virus mutation has caused some reagents to fail, and listed several kits that may be affected by mutation. This means that virus mutation may have led to the failure of some nucleic acid detection or persistent false negative.

The FDA listed several kits that may be affected by mutation:

Accula SARS-Cov-2 detection (Mesa Biotech): If the virus mutates at the 28881st base (GGG to AAC), the detection of this kit will be affected;

TaqPath COVID-19 Combo Kit (Thermo Fisher Scientific): This kit detects three genes at the same time, and the variant B.1.1.7 appearing in Britain will affect one of the detection results;

Linea COVID-19 detection (Applied DNA Sciences): This kit detects two genes at the same time, and the variant B.1.1.7 appearing in Britain will affect one of the detection results;

Helix, an American company doing nucleic acid detection, also noticed the influence of virus mutation on detection. The company’s nucleic acid detection simultaneously detected three Covid-19 genes: ORF1ab, N, and S. Because the B.1.1.7 strain that appeared in Britain had deletion mutation in S gene, ORF1ab and N could be detected in the detection, but S gene could not be detected (4). This phenomenon is called "S gene withdrawal".

In addition, the sensitivity of reagents from different manufacturers to COVID-19 is different, and the country also organized a national evaluation of reagents last year. butIn an evaluation study on the consistency and detection ability of seven domestic novel coronavirus nucleic acid detection kits published by Chinese Journal of Laboratory Medicine in July, 2020, it was proposed that "some kits have poor detection ability for weakly positive samples,It is suggested that weak positive samples should be rechecked by kits from at least two manufacturers to ensure the accuracy of the results."

Several targets of nucleic acid detection in Covid-19 are ORF1ab gene, N gene and S gene.

In the Technical Guide for Laboratory Detection of Pneumonia Infected in novel coronavirus issued by China CDC (hereinafter referred to as the Technical Guide), the two targets of nucleic acid detection in Covid-19 are ORF1ab gene and N gene respectively.

On January 6th, the Weekly Report of China Center for Disease Control and Prevention published the results of gene sequencing analysis of two cases of Covid-19 infection in Shijiazhuang and Xingtai. According to the published results, the strain prevalent in Gaocheng, Hebei Province, is different from the strain found in other places in China recently, and is homologous to the strain reported in Russia last July, belonging to strain B.1.1.123

Coincidentally, the mutation happened at the 28881 ~ 28883 bases of the virus gene of this strain, and this is exactly the position of the forward primer of the N gene!

This also explains why there were many negative results at that time.

I guess this is one of the reasons why the criteria for judging nucleic acid positivity have also changed.The judgment position that the single target is still positive after retest is positive.

Figure/Current Criteria for Judging Positive Cases in Technical Guide

Solution:

1. Require manufacturers of nucleic acid reagents to conduct confirmatory experiments on the current mutant strains and propose technical solutions.

2, all localities should introduce at least two kinds of better quality detection reagents, for control use.

3. Information about the failure of test reagents that may be caused by mutated viruses should be effectively and widely reported in domestic laboratories.

Six, the standard implementation in the process of laboratory testing

the pastAccording to the guidelines issued by relevant institutions, the collected samples need to be inactivated at 56℃ before nucleic acid detection, which is very likely to degrade the Covid-19 nucleic acid, which will lead to the failure of normal detection and ultimately improve the false negative rate.In the early daysInactivation treatment is carried out for the sake of biological safety, to protect the staff engaged in testing from virus infection.

But later, there were many voices of doubt in the academic circles, becauseViral RNA is easily degraded by ribonuclease, because this enzyme has the highest activity at 60℃. Ribonuclease comes from two aspects, one is the sample cells, and the other is the foreign pollutants in the process of collection, preservation and transportation.

Last February, there was a similar research article.The high-temperature inactivation process before virus nucleic acid extraction significantly reduces the amount of detectable virus nucleic acid templates, which has been pre-published on the platform of scientific papers of China Academy of Sciences.

And last May,The Journal of Clinical Chemistry published the research of Chinese scholars on Covid-19’s false negative test.The study confirmed that,Thermal inactivation can cause the increase of Ct value reflected by PCR and cause false negative results.Specifically, 46.7%(7/15) of the weakly positive samples were false negative after inactivation (a surprising proportion). Another inactivation method is to inactivate the virus by dissolving the virus protein with guanidine hydrochloride. This study confirmed that guanidine hydrochloride had little effect on PCR reaction, and the false negative rate was low, although there was also a false negative rate of 13.3%(2/15).

Related address: https://academic.oup.com/clinchem/article/66/6/794/5815979

I also inquired whether there was a 56-degree inactivation step in the detection process of CDC in the United States. Although my English ability was poor, I didn’t see this step by machine translation.

Including some other documents retrieved, it is also very clear that 56-degree inactivation does have a great influence on weakly positive specimens.

No matter the Manual of Nucleic Acid Detection in Medical Institutions in novel coronavirus (Trial) on July 13th, 2020 or the Manual of Nucleic Acid Detection in Medical Institutions in novel coronavirus (Trial 2nd Edition) on December 30th, 2020, there are corresponding descriptions.For the laboratory that has been inactivated with the sampling tube containing guanidine salt, there is no need to inactivate at 56 degrees for 30 minutes.This is only true if non-inactivated sampling tubes are used.

However, I learned from the familiar laboratory leaders that this is not the case. Many laboratories still require samples to be pretreated at 56 degrees for 30 minutes regardless of whether the tubes are inactivated or not. I can understand that they are worried about hospital infection and laboratory exposure. But generally speaking, reducing the false negative rate, increasing the detection amount and taking corresponding measures to control the epidemic situation as soon as possible, I think the corresponding suggestions in the corresponding guidelines are also the best choice from the overall situation and supported by data.

Our laboratory should not control the occurrence of hospital sensation and laboratory exposure at the expense of reducing the detection rate, but should focus on stricter control of experimental steps, more cautious PPE wear and higher laboratory environment.

Solution:

1. It is suggested that the state give special instructions to laboratories at all levels on this matter.

2. It is suggested that the country should further study the preservation solution of sampling tubes, and if there is any preservation solution that can not reduce the detection rate at 56 degrees for 30 minutes, it can also be recommended.

The above zero zero always said a lot of points, mainly about how to reduce false negative conclusions, hoping to give you a reference.

It’s been many days since I wrote this afternoon, mainly considering Spring Festival travel rush. Although the scale of Spring Festival travel rush is reported to have dropped by more than 75% this year compared with previous years, the population flow is still very strong. We may face the rising trend of an epidemic after Spring Festival travel rush, and how to make the work better may be a more urgent need before us.

Xinhua News Agency, Beijing, September 2ndQuestion: How to upgrade consumers’ enjoyment of trade-in support of overweight in various places?

Xinhua News Agency reporters Xie Xiyao, Li Xiaoting and Gong Liankang.

Recently, the "upgraded version" policy of promoting the trade-in of automobiles and home appliances at the central level has been introduced one after another. The reporter recently visited markets in Beijing, Hubei, Chongqing, Fujian and other places, and learned that all localities have introduced detailed rules for the replacement of old consumer goods in light of local actual conditions, expanded the coverage of subsidized products, upgraded subsidies, made the application process more convenient, and increased consumers’ willingness to purchase.

Government subsidies are superimposed on enterprises to make profits, and new subsidies for automobile replacement and renewal are added.

On the evening of August 27th, the reporter went to the Geely Yinhe Wuhan Star Experience Center in Hanyang District, Wuhan. The slogan of "trade-in" subsidy for cars in the store was everywhere, and many citizens went to the store to see cars and consult preferential policies.

The salesperson took the store’s best-selling model Geely Yinhe E8 as an example and calculated a "detailed account" for the reporter:

For a new car with an original price of 165,800 yuan, if the customer’s old car meets the scrapping conditions, the maximum state subsidy can be 20,000 yuan; Or transfer the car under his name, you can get a replacement subsidy of 12,000 yuan. During this period, you can also apply for a trade-in coupon of up to 2,000 yuan in Wuhan at the same time, plus a discount of more than 10,000 yuan from manufacturers and 4S stores, and the maximum superimposed discount for buying this new car can reach more than 30,000 yuan.

According to the national policy, for individual consumers who meet the provisions of the Detailed Rules for the Implementation of Vehicle Trade-in Subsidies and scrap old cars and buy new ones, the subsidy standard will be increased from 10,000 yuan for new energy passenger cars and 7,000 yuan for fuel passenger cars to 20,000 yuan and 15,000 yuan respectively. In addition to scrapping and updating, this policy will also include replacement and updating in the scope of subsidies, and support local governments to carry out replacement and updating independently.

At present, following the rhythm of national policies, local governments have successively launched trade-in schemes focusing on the local automobile market.

The national dicing and matching funds in Hubei Province are more than six times the size of the funds before the afterburner measures. The maximum subsidy for car scrapping and renewal is 20,000 yuan, and the maximum subsidy for replacement and renewal is 16,000 yuan.

Beijing has made it clear that the newly purchased new energy vehicles after replacement include not only pure electric vehicles, but also plug-in hybrid vehicles (including extended-range vehicles) and fuel cell vehicles, and all of them can enjoy replacement subsidies if they are transferred inside and outside Beijing.

Shanghai puts used cars in an important position in the trade-in policy, encourages the development of used car distribution business, and makes it clear that the average age of used cars will be reduced by one year by 2027 …

Government subsidies are superimposed on enterprises to make profits, new replacement and renewal subsidies are added, and consumers’ willingness to buy new cars is increased.

Up to now, the trade-in of consumer goods in Hubei has benefited more than 400,000 consumers, driving the sales of new cars and home appliances to 12 billion yuan. Wuhan has achieved the goal of trade-in of automobiles for the whole year ahead of schedule; As of mid-July, Hunan has received more than 8,600 applications for automobile scrapping and renewal subsidies, and more than 23,000 applications for replacement and renewal subsidies, which has driven automobile sales to exceed 5.5 billion yuan. From the release of the National New Deal to September 1st, the cumulative amount of old-for-new subsidies in Chongqing reached 9,748, and the cumulative sales of automobiles exceeded 1.837 billion yuan.

According to the data of the Ministry of Commerce, as of 10: 00 a.m. on September 1, more than 810,000 applications for car scrapping and renewal subsidies were received. From January to July, the national automobile retail sales reached 11.556 million, up 2.3% year-on-year. Among them, the retail sales of new energy passenger cars was 4.988 million, a year-on-year increase of 33.7%; The number of used cars was 10.992 million, a year-on-year increase of 6.3%.

The subsidy for home appliance replacement will be expanded, and the on-site application will be reduced immediately.

Mr. Zhou of Nanchuan District, Chongqing recently bought a Haier Class 1 energy-efficient air conditioner with a price of 2,499 yuan and enjoyed a government subsidy of 499.8 yuan for trade-in. "Government subsidies are very cost-effective, and it is very convenient to apply for money immediately." Mr. Zhou said.

On August 26th, Chongqing’s "upgraded version" green smart home appliances trade-in subsidy policy landed. On the first day of the implementation of the policy, the city issued a government subsidy of 8.165 million yuan, which directly led to the sales of home appliances of 42.6335 million yuan.

The reporter learned from the Chongqing Municipal Commission of Commerce that at present, the state’s pre-allocated funds to support trade-in have been issued to Chongqing, and the local governments will match the funds in proportion to jointly promote the trade-in of consumer goods.

The state has made it clear that eight types of household appliances enjoy a subsidy standard of 15% to 20% of the sales price, with a maximum subsidy of 2,000 yuan per piece. At the same time, support local governments to independently determine the varieties of subsidized "8+N" household appliances. Up to now, many places have successively issued implementation rules for the implementation of home appliance trade-in.

Chongqing has made it clear that individual consumers will enjoy 15% to 20% of the sales price of each type of household appliances when they purchase 11 types of household appliances with energy efficiency or water efficiency standards of Grade 2 or above; In terms of superimposed subsidies for enterprises, consumers can enjoy a 2% trade-in subsidy if they sell nine categories of old household appliances and buy any kind of products with energy efficiency or water efficiency of Grade 2 or above.

Beijing consumers can access the "Jingtong" applet through Alipay, WeChat, Baidu, Meituan and other channels, and receive the subsidy qualification codes of more than 10,000 household appliances in 8 categories, and enjoy preferential treatment in the payment link.

On the basis of eight types of household appliances, Guangdong has added three types of products, such as mobile phones, tablets and smart wearable devices, as well as other N-type products that are actually included in the scope of subsidies in various cities, forming an "8+3+N" product category.

From the central government to the local government, the subsidy policy has clearly defined the energy efficiency standards, and only subsidizes energy efficiency products of Grade 2 and above. "Trade-in is not a simple replacement of similar products, but a demand that tends to be higher-end, smarter, more environmentally friendly and more personalized, and supports the transformation and upgrading of household consumption through trade-in." Chen Yaoting, a professor at the Business School of Minnan Normal University, said.

Continue to open up new blocking points and smooth the resource circulation chain.

Recycling has always been a blocking point that affects trade-in consumption, and it is also the key to smooth the recycling of resources.

Fujian Quantong Resource Recycling Industrial Park, located in Zhangzhou Development Zone, Fujian Province, has a truckload of used household appliances entering the factory, weighing, unloading, acceptance, bar coding and warehousing, and then entering the dismantling process. Every day, about 2000 sets of waste household appliances are treated here in a standardized way.

Driven by the trade-in policy, Quantong has established strategic cooperation with recycling enterprises under Midea Group to realize the recycling system of products from sales, recycling to standardized dismantling.

The national policy is clear, all localities should strengthen the construction of digital platforms, learn from each other’s experience, strengthen data analysis, and timely and accurately grasp the information of the whole process of home appliances replacement, purchase and disassembly. The reporter visited and learned that under the guidance of the trade-in policy, the diversified recycling pattern of used household appliances is accelerating.

"Old household appliances are not limited to brands and years, and they can provide one-stop trade-in services such as free door-to-door dismantling of old machines and free transportation." He Yuanlin, general manager of Dahai Daming Trading Co., Ltd., a distributor of Haier Zhangzhou, said that the company is docking with dismantling enterprises with relevant qualifications, establishing a standardized recycling system for used household appliances, and at the same time promoting the development of community services for household appliances.

On September 2, Haier Zhijia Recycling Interconnection Factory was completed and put into operation in Laixi, Qingdao, with an annual dismantling capacity of 3 million units. Shijiazhuang city has perfected the comprehensive utilization system of renewable resources by the mode of "government+property+third party"; Hunan will include the recycling outlets of renewable resources such as waste household appliances into the construction of a convenient living circle for a quarter of an hour; Gree, Changhong and other home appliance companies actively adopt the "internet plus Recycling" method to provide professional old machine recycling services …

Insiders pointed out that with the increase in the number of places to promote the implementation of the old-for-new policy, it will drive the government, enterprises, platforms and other forces to join the field of recycling, and work together to improve the construction of the recycling network of used household appliances, so that consumers are "easier to get rid of the old and more willing to get new ones".

When taking takeout, you can bring disposable gloves, or use paper towels to separate your hands from the packaging bag. After taking the takeaway, you can remove the layers of packaging under the protection of gloves or paper towels and throw them into the trash can. Then use the soapbox flowing water to absorb it at the first time, or use antibacterial hand gel containing alcohol to clean your hands. However, we still suggest cooking by yourself and bringing meals. If you go to a restaurant or order takeout, it is recommended to order hot food instead of cold food; If possible, reheat the food before eating to ensure it is cooked thoroughly; Always remember to maintain hand hygiene, wash your hands before and after meals and after touching easily contaminated items.

　　　 Hong Kong Book Fair: A Carnival for Common People to Read.

　　The special status of Hong Kong has made the sales characteristics of Hong Kong’s book industry, which can’t be copied by mainland or overseas book industry.

　　Our reporter/Chen Xiaoping

　　On July 21st, when Typhoon No.3 "Candu" formed in the South China Sea, the 21st Hong Kong Book Fair, which lasted for one week, kicked off at the Hong Kong Convention and Exhibition Center in Victoria Harbour. The coming typhoon has not stopped Hong Kong people’s great enthusiasm for participation. On the overpass leading to the Convention and Exhibition Center in Central Square, Hong Kong people who came to buy books with carts and suitcases jostled each other. Security guards need to take measures to restrict the release, so as to control the flow of people at any time and maintain order.

　　From the 200,000-person attendance of the first book fair in 1990 to the 920,000-person attendance this year, the annual attendance of the Hong Kong Book Fair has been hitting a new high-today, almost one in every seven Hong Kong people goes to the book fair-although this has made the Hong Kong Book Fair a "fair" for books. The Hong Kong Trade Development Council has made this book business stronger and stronger, and such a lively scene is unmatched by Beijing, Shanghai and Chengdu book fairs.

　　Visit book fairs and buy books once a year.

　　From the Wan Chai subway station to the Convention and Exhibition Center, there are all kinds of publishers’ advertisements, book exhibition posters and flags. At the entrance to the venue, people have to wait for the people in front to fully enter the exhibition before releasing the next batch of visitors. It is said that the longest time, the queue was one kilometer, and citizens had to wait for more than 40 minutes to enter the venue.

　　"I really don’t know what supports the enthusiasm of Hong Kong people to visit the book fair," said a Beijing reporter who participated in the Hong Kong book fair for the first time. Seeing such a scene makes people dizzy, and if the goal of buying books is not clear, it is very painful to find a book in the book fair, just like looking for a needle in a haystack.

　　Including Chinese and English booksellers (bookstores) across the Taiwan Strait and three places, as well as foreign language books from many countries, all publishing houses and bookstores directly enter the venue to set up booths to sell books. Just like the temple fair in Beijing, there are constant shouting and selling in the venue, and there are even booths selling books with banners of "20% off for one book, 30% off for six books and 6.5% off for ten books".

　　On the 22nd, the second day of the book fair, the storm, accompanied by lightning, did not stop Hong Kong people from buying books at the book fair. From time to time, I see book buyers with suitcases, and most of them are mainstream bestsellers. Teenagers prefer "light novels", while the elderly prefer health books. The so-called "light novel" refers to the combination of novels and cartoons. It is a kind of entertaining literary book, which tells stories with cartoons, pays attention to pictures and has shots, and is mostly imported from Japan.

　　During the summer vacation, the main force during the day is middle school students, and some "light novels" are even sold in bundles. In the evening, the age of book buyers goes up. After dinner on Friday, office workers become the main force of the book fair. On the weekend, married with children’s parent-child group appears at the book fair, and Hong Kong people enjoy the seven-day book carnival as a holiday.

　　It has been 21 years since the Hong Kong Book Fair. Visiting the book fair in these seven days has become an annual habit of Hong Kong people. Many young people don’t usually visit bookstores to buy books. They will save a sum of money to buy books at the annual book fair, and even compare with friends.

　　For this phenomenon, Ma Jiahui, a Hong Kong cultural person, explained: "This is a tragedy in Hong Kong. In Hong Kong, there is not even a decent bookstore, and the usual pace of life is very tight. Ordinary people read and buy books less frequently."

　　Hong Kong people advocate fast food culture, and newspapers and periodicals are the main reading contents of the citizens. Young people in Hong Kong usually don’t like reading, and they are not encouraged to read. They don’t know which bookstore to buy books. Therefore, as Ma Jiahui said, if there is no book fair, young people in Hong Kong may not buy books 365 days a year.

　　Hong Kong Commercial Press is a publishing house with the largest retail bookstore in Hong Kong. It has 21 bookstores in Hong Kong and Macao, and also has a professional English law bookstore. The annual turnover of the whole bookstore is 600 million Hong Kong dollars. However, in charge of such a leading enterprise in the book industry in Hong Kong, managing director Lu Guo also lamented that the book market was difficult to do. Although the flagship store of Hong Kong Commercial Press in Tsim Sha Tsui is one of the bookstores that mainland scholars like to visit in Hong Kong, the bookstore has suffered the fate of moving three times in five years because of the high rent and the owner’s failure to renew the contract.

　　Ma Jiahui said that Hong Kong bookstores were all killed by real estate developers.

　　Readers inside and outside the book fair

　　In February, 1923, Sun Yat-sen gave a speech at the University of Hong Kong, saying that his thought originated in Hong Kong. But four years later, when Lu Xun went to Hong Kong to give a speech, a group of literary youths complained to Lu Xun that Hong Kong was a "desert area" ideologically, and the statement that Hong Kong was a "cultural desert" was widely spread.

　　All along, the Hong Kong Trade Development Council has been organizing book fairs with the idea and concept of business management. From asking stars to take the lead in reading and writing books as a marketing tool, to "the second kind of books and periodicals" with pornographic and violent content becoming the focus of the book fair, and then to the invasion of the tender model photo album into the book fair, which also makes the negative news about the book fair continue every year, and the book fair also expands constantly every year, with the increase of exhibition halls, booths and sales figures of books.

　　In 2005, Fred Lam, the new president of the Hong Kong Trade Development Council, proposed that the Hong Kong Book Fair should pay equal attention to culture and commerce. Fred Lam suggested that the TDC is a commercial organization, not a cultural organization, and it is not good at doing cultural things. "We should find excellent cultural institutions and groups in Hong Kong to do this.". Later, they hired the Hong Kong Arts Development Council, Ming Pao Group, Asia Weekly and other cultural organizations as staff officers, and finally decided to cooperate with Asia Weekly to invite writers and cultural celebrities from three places across the Taiwan Straits to give lectures at the book fair.

　　This year’s book fair also opened the "Hong Kong Writers’ Tour 2010" exhibition area for the first time to promote outstanding local writers in Hong Kong, and followed the example of Frankfurt Book Fair to join the works recitation.

　　This year’s book fair invited more than 90 writers to participate in more than 270 cultural and outreach activities. Among them, invited lecturers from the Mainland include Feng Jicai, He Weifang, Pan Shiyi, Zhang Yihe and Han Han. In addition, the speakers of the "Famous Lectures" include Zhou Guangqian, Ge Liang and Lin Peili from Hongkong, Chen Wenxi, Liu Kexiang, Lan Bozhou and Tang Nuo from Taiwan Province, jade y. chen living in Germany and Du Weiming from the United States.

　　In a lecture hall with less than 200 people, Liang Wendao, a Hong Kong writer, is sharing his creative experience with readers. The audience included old people with white hair, peers from Liang Wendao, and more young people, many of whom came from Guangdong to attend the Hong Kong Book Fair.

　　A local young man in Hong Kong, wearing glasses, T-shirt shorts and a pair of straw flip-flops on his feet, listened carefully and took notes on a single piece of paper. It can be seen that young people like Liang Wendao very much, and listen to the lectures carefully.

　　Liang Wendao said that the characteristic of Hong Kong writers is to do their own things silently and write their own books. It seems that the readers in Hong Kong are the same.

　　But more readers are actually outside the book fair. "I haven’t been to the book fair for a long time. My writing doesn’t need to deal with modern people, but is related to the dead." On the other end of the phone, Huang Canran, a Hong Kong poet and translator, told China Newsweek. He goes to work at five o’clock every afternoon and writes in the early hours of the morning. For him, in this busy morning, the day has just ended.

　　In Hongkong, there is also a group of English-reading people. No one has counted the size of this group, but Ma Jiahui told a story: once he made an appointment for a book review and introduced the Chinese version of Said’s books on music. Later, his friend in the Hong Kong Commercial Press told him that the bookstore kept the original English version of the book for one year and hardly sold a few copies. However, after the book review, the original English version sold 20 copies within a week, while the Chinese translation only sold a few more.

　　Hong Kong books export to domestic market.

　　Since 2003, when the mainland opened free travel for tourists to visit Hong Kong, the Hong Kong Book Fair began to welcome mainland readers. Subsequently, the Hong Kong Book Fair set up a "visiting channel", through which you can get preferential ticket purchase. Through these measures, the organizers attract mainland readers to buy books in Hong Kong. According to the statistics of the Hong Kong Trade Development Council, the number of people who entered the 20th Hong Kong Book Fair through the "visiting channel" reached 10,000 last year, and the organizers thought that a considerable number of mainland tourists should follow Hong Kong friends or queue up for admission. In fact, the number of people from the mainland who went to the Hong Kong Book Fair was far more than that.

　　"Export to domestic market" is one of the characteristics of Hong Kong books. Most of the authors of Chinese works in Hong Kong, especially academic works, come from mainland scholars, and these academic works have returned to the mainland, which has formed a big market, except for local and overseas research institutions. Scholars’ "export" and works’ "domestic sales" are an intriguing structure of the Hong Kong book market.

　　The Chinese University of Hong Kong Press, which has published the works of mainland scholars such as How the Red Sun Rises: The ins and outs of Yan ‘an Rectification Movement by Gao Hua, a professor of history at Nanjing University, and Xu Qingquan, deputy editor-in-chief of Yanhuang Chunqiu, the case of Ding Ling and Chen Qixia’s "anti-Party clique", has gathered a group of excellent mainland scholars’ resources. This university publishing house, which aims at "promoting Chinese and Western cultures and spreading ancient and modern knowledge", is a non-profit academic publishing institution. In the past 30 years, it has published a large number of academic works in both Chinese and English, with authors ranging from Qian Mu and Xu Zhongyue to William Theodore de Bary and Needham. Its topics span from traditional China culture to contemporary China studies, and it has established a stable global sales channel.

　　Gan Qi, president of The Chinese University of Hong Kong Press, told China Newsweek that the press followed the anonymous review system of western university press, and the manuscripts of academic works provided by scholars all over the world must be anonymously reviewed by at least two experts in the industry and submitted to the Academic Books Editorial Committee for final approval before they can be accepted for publication or published after being revised by the author. The editorial department, reviewers and academic committees are integrated to ensure that the manuscript has new ideas or new materials, and in short, it has promoted and contributed on the basis of research in the same field. It is under the guarantee of this system that the publications of this society can maintain the content quality and diversified positions for a long time, which has stimulated the academic thoughts in the mainland.

　　The booths of The Chinese University of Hong Kong Press, Hong Kong Oxford University Press, Hong Kong Commercial Press and Hong Kong Sanlian Bookstore are still the favorite bookstall for mainland readers. ★

　　At 17: 00 on December 28th, the Information Office of Xi ‘an Municipal Government held a press conference on the joint prevention and control of epidemic situation in COVID-19 (Game 39), attended by Lv Yongpeng, deputy director of Xi ‘an Health and Wellness Committee, Yang Yongtao, deputy head of Chang ‘an District Government, and Guo Xiaohui, deputy director of High-tech Zone Management Committee, to report the latest situation of epidemic prevention and control in Xi ‘an.

　　The press conference revealed that starting from December 28, Yanta District, Chang ‘an District and High-tech Zone will conduct a regional nucleic acid screening every day.

　　At the press conference, Lv Yongpeng, deputy director of Xi ‘an Health and Health Commission, introduced that at 12 o’clock on December 27th, Xi ‘an started a new round of nucleic acid screening. By 12 o’clock on the 28th, a total of 12,317,000 people had been sampled, and the result was 11,347,800.

　　In this round of nucleic acid screening, a total of 5,077 sampling points and 11,669 sampling stations were set up, with more than 31,000 sampling personnel and 132,900 service support personnel, with a daily detection capacity of 1.6 million tubes. The workflow of each sampling point is standardized, guiding and persuading the masses to keep "one meter line" and scanning code, so that the sampling work runs efficiently.

　　With the effective organization of staff and the active cooperation of citizens and friends, the efficiency of nucleic acid sampling has been greatly improved. From 12: 00 to 20: 00 on the 27th, a total of 11,080,800 people were sampled, and more than 11 million people were sampled in 8 hours. Yanta District, Chang ‘an District and High-tech Zone will conduct nucleic acid screening once a day from December 28th. According to the situation, Lianhu District will increase the frequency of nucleic acid screening in the whole region; 1250 sampling personnel were transferred from other districts, counties and development zones to support nucleic acid screening in the above four districts, counties and development zones.

　　According to the spirit of the Notice on Adjusting Relevant Measures for Epidemic Prevention and Control in Our City (No.58 [2022] of Great Epidemic), all citizens will carry out nucleic acid testing twice a week from September 20th, and fulfill the requirements of normalized nucleic acid testing, which does not leak one person, but should be thoroughly checked. The relevant matters are hereby notified as follows:

　　First, the centralized sampling time for normalized nucleic acid detection is from 6: 00 to 18: 00 every Tuesday and Friday.

　　Two, the normalization of nucleic acid detection by the district, city and county (pilot area) unified organization, full participation. Please follow the arrangement of the street (township) and community (village) where you are located, go to the nearby sampling point at the wrong peak, wear a mask throughout the sampling, keep a distance of more than 1 meter from others, and do not talk or gather.

　　Three, all kinds of key populations in accordance with the requirements of the city headquarters to determine the frequency of nucleic acid detection, in the designated time to participate in the sampling and testing of nucleic acid sampling points of key populations.

　　Nucleic acid detection is an important means of epidemic prevention and control. The general public should take the initiative to participate in the detection, actively cooperate with the "site code" inspection, and jointly build a barrier for epidemic prevention and control to protect the hard-won epidemic prevention achievements!

Many people have had this feeling that their chest suddenly "thumped" as if their heart had stopped. This situation is likely to be premature beats.

Premature beat is that a heartbeat rhythm is advanced, and there is a long interval after beating ahead. Some patients with less premature beats have no obvious feeling, but occasionally feel some discomfort or slight palpitation in the chest. If premature beats occur frequently, it will cause symptoms such as palpitation, shortness of breath, chest tightness and fatigue, and even worsen the original heart disease, which requires active treatment.

Western medicine treatment of premature beats is mainly "anti-"

For the treatment of premature beats, the traditional western medicine treatment method is to choose antiarrhythmic drugs, which only aim at a certain level and a certain part of arrhythmia, ignoring the interaction between factors at the same level and the interaction between different levels, and then aiming at the single cause of arrhythmia, blindly adopting the "anti-"treatment method can not solve the fundamental problem. Moreover, the side effects of antiarrhythmic drugs are increasingly obvious, which not only has serious extracardiac toxicity and leads to liver and kidney damage, but also may cause more complicated arrhythmia and even worsen the original arrhythmia symptoms. Another point is that western medicine can not effectively treat bradyarrhythmia, so there is no good way to treat arrhythmia such as sinus bradycardia with ventricular premature beats.

The treatment of premature beats with traditional Chinese medicine focuses on "regulating" 　 　 　 　 　 　 　 　 　 　 　 　 　

Shensong Yangxin capsule, a traditional Chinese medicine, has realized the thinking change from "resistance" to "modulation" in clinical treatment of premature beats. "Modulation" is the whole regulation, which takes the integration of various factors and mechanisms for regulating premature beats as the core, and starts from the interrelation among molecules, cells, tissues, the whole heart and even the whole human body, so as to regulate the autonomic nervous function of the heart, block multi-ion channels, improve the metabolism of myocardial cells, and restore the whole function of the heart, and has a good curative effect on all kinds of premature beats.

In the evidence-based medical research of Shensong Yangxin Capsule, which was attended by more than 500 doctors from 36 3A hospitals in China, 188 cases of non-organic ventricular premature beats and 671 cases of organic ventricular premature beats caused by heart diseases such as coronary heart disease and myocarditis were treated with Shensong Yangxin Capsule. Compared with the curative effect of slow heart rhythm, the results of 24-hour dynamic electrocardiogram examination show that Shensong Yangxin capsule has a good therapeutic effect on both non-organic ventricular premature beats and organic ventricular premature beats, and its curative effect is significantly better than that of slow heart rhythm, and there is no adverse cardiac reaction. By taking Shensong Yangxin Capsule, the symptoms such as palpitation, shortness of breath, chest tightness, fatigue, dizziness and sweating disappeared.

In addition, the curative effect of Shensong Yangxin Capsule on sinus bradycardia with ventricular premature beats and heart failure with ventricular premature beats has also been confirmed by evidence-based medical research.

A randomized, double-blind, placebo-controlled, multi-center clinical study of Shensong Yangxin Capsule in the treatment of sinus bradycardia with ventricular premature beats, which was jointly participated by 33 3A hospitals in China, showed that the number of premature beats in the treatment group decreased by 1827 times /24 hours, the rate of decrease of premature beats was 71.01%, the heart rate increased by 6.25 times/minute, and the heart rate percentage increased by 11.38%. The research results show that Shensong Yangxin Capsule can improve ventricular premature beats safely and effectively, and at the same time, it can increase sinus heart rate, thus screening out effective and safe therapeutic drugs for patients with sinus bradycardia and ventricular premature beats at home and abroad.

Evidence-based medical research on Shensong Yangxin Capsule in the treatment of heart failure with ventricular premature beats was completed by 31 domestic 3A hospitals for two years. The results confirmed that Shensong Yangxin Capsule can significantly reduce the number of patients with 24-hour ventricular premature beats and significantly improve the decline rate of 24-hour ventricular premature beats on the basis of standardized treatment of chronic heart failure. At the same time, it can increase the left ventricular ejection fraction, improve the cardiac function classification, reduce the plasma concentration of pro-brain natriuretic peptide (NT-ProBNP), increase the walking distance of 6 minutes, improve the quality of life of patients, and have good safety.

Based on the research results of Shensong Yangxin Capsule in treating premature beats, Shensong Yangxin Capsule was recommended by China Expert Consensus of Ventricular Arrhythmia in 2020.

When the hybrid car developed into the second half, it was not the user’s taste that became higher, but the user’s eyesight became awkward. It is increasingly found that price is not the only indicator of hybrid cars, and cars with high performance, high intelligence and high safety are worthy of the money in their pockets. Cars are not toys. They will be replaced and eliminated after buying for one or two years, but will bring long-term high-value travel experience. Therefore, cars manufactured with high standards are worth starting with.

The 2025 LECK 08EM-P, which was launched on August 8, is a high-value hybrid SUV choice worthy of users’ travel and life in terms of strength and quality.

Between low price and high value, there are always people who prefer the latter.

In the former automobile market, there were always people who thought that low price was king. As users became more aware of automobiles, they tended to be more value-oriented.

The 2025 LECK 08EM-P has six models: 120 long battery life Plus version, 120 long battery life Pro version, 120 long battery life version, 245 long battery life Pro version, 245 long battery life Halo version and 220 four-wheel drive performance Halo version. The battery life in pure electric mode adopts stricter CLTC working conditions. CLTC is based on the actual driving conditions in China, including urban, suburban and high-speed driving conditions, and the battery life test is more in line with it. On the surface, the LEICK 08EM-P with a low battery life of 120km seems to be equivalent to the 121km Tang DM-i, but the Tang DM-i still uses a relatively loose NEDC working condition count. In terms of comprehensive endurance, the LECK 08EM-P with CLTC working condition of 1400km is obviously more realistic than the Tang DM-i with NEDC working condition of 1100km.

?On the power system level, the Lectra 08EM-P super extended-range electric system consists of P1 and P3 motors +P4 motor +1.5T electric hybrid engine, which together form a high-performance architecture. Specifically, the P1+P3 motor architecture is a rear-wheel drive model, and the P1+P3+P4 motor architecture is a four-wheel drive model. Logically, the engine generates electricity for P1 motor, and the rear-drive vehicle is driven by P3 motor, with a maximum power of 160 kW and a peak torque of 350 N m.. The four-wheel drive model is driven by P3+P4 motor, and the peak power of P4 motor is 156 kW. The comprehensive maximum power of the system is 436 kW, the comprehensive maximum torque is 905 N·m, and the acceleration of 100 kilometers is only 4.6 seconds.

The DHT three-speed transmission of LINKE 08EM-P can realize the flexible switching between engine and motor, and bring more accurate power distribution under different road conditions. In the specific operation experience, the driver of the 08EM-P can choose the appropriate gear in different road environments and match the power with different intensities, thus bringing a precise sense of control. And the shifting logic is very clear, and the power acceleration is not all of a sudden, but a linear acceleration experience.

In contrast, Tang DM-i’s CVT gearbox has the advantages of strong ride comfort, but its disadvantages are also quite obvious: first, CVT gearbox is prone to cold protection problems, and it may take a long time to start in cold environment, which may also lead to the inability of vehicles to speed up effectively. Secondly, the transmission belt of CVT gearbox is fragile and easy to be damaged in harsh driving environment, which requires more frequent maintenance and replacement, and the actual vehicle maintenance cost is higher. Thirdly, CVT gearbox will obviously feel the lack of power on vehicles with strong power, especially on uphill sections, which is one of the reasons why BYD plug-in and hybrid vehicles have not adopted the strategy of high power.

In the era of intelligent flooding, Linke 08EM-P has implemented the user’s needs.

At present, the new energy vehicle market has entered the era of intelligent flooding, which is manifested in the stacking of non-vehicle intelligent configurations, such as the "refrigerator color TV sofa" that people often vomit. On the aspect of integrated intelligence, LEEK 08EM-P upgraded the car system to OTA version 1.6.0. The overall intelligent cockpit performance of the car is different from the current flood era. It follows the principle of "making the car practical and intelligent to the extreme" and implements the needs of users.

If you are installed with the identity of "Leader 08EM-P Owner" now, you don’t need a physical key to get on the bus, and your Apple mobile phone, watch and proximity can open the door for you, realizing a feeling of unlocking/locking, and making your travel life more scientific and technological. When you sit in the driver’s seat, you don’t need to look down at your mobile phone or central control screen navigation when driving, because there is the largest 92-inch AR-HUD mass-produced in the industry, which directly presents three-lane information, AR navigation, ADAS assistance and other information on the front windshield. In terms of car experience, the LYNK Flyme Auto car system of LINKE 08EM-P is the first to take the Antola 1000 Pro computing platform, which integrates two 7nm "Longying No.1" chips independently developed in the industry, and the computing power of a single chip is comparable to that of Qualcomm 8155 car chip, and it has larger running and storage memory, which is smoother and faster in car startup and functional experience.

When you want to watch the video on a big screen, use the 15.4-inch ultra-clear full screen of LTPS LCD display technology, which has a picture quality of 2.5K and a color gamut as high as 85%, which can show more colors. The sound quality experience is even more impressive. As the only SUV model equipped with Harman Kardon 23 plus WANOS panoramic sound within 200,000, the Lectra 08EM-P has brought a million-level extreme sound experience at a price of 200,000. In terms of sound surround telepresence, the top "sky sound" surround channel is added to the Lectra 08EM-P cockpit, which enhances the depth and telepresence of the sound image compared with the two-channel stereo, and it seems to be surrounded by sound when sitting on it. In addition, the car system is equipped with WANOS Panoramic Audio APP, with its high-quality panoramic audio-visual entertainment resources to realize audio-visual synchronization, which can bring you and your family a more immersive and shocking audio-visual experience.

On the intelligent voice level, Aicy voice assistant can support four-tone recognition, which has higher understanding and execution ability, not only supports custom wake-up words, but also can customize a variety of images to make the dialogue more vivid and interesting. Crucially, Aicy voice assistant can realize multiple rounds of communication according to the context of the whole context, which really brings an intelligent experience of "seeing and speaking".

Not only that, LINKE 08EM-P also has innovative functions of sentry mode and car wash mode. Sentinel mode In the parking scene, vehicles can monitor suspicious targets by looking around the fisheye camera, rely on the acceleration sensor to detect the risk of collision, and give a double flash warning to the outside world in time. It can also record and store suspicious scenes and notify the owner. When the car wash mode is turned on, the vehicle will close the window, trunk, charging cap, fuel cap, wiper, etc., and disable the approaching vehicle to unlock and leave the vehicle, effectively preventing water seepage and ensuring vehicle safety.

In intelligent driving, LEEK 08EM-P is equipped with Lynk Co-Pilot Navi intelligent navigation assistance system, which not only performs sensitive and fast in daily adaptive cruising, overtaking, going up and down ramps and other road conditions, but also has various lane-changing functions such as autonomous lane change and voice control lane change, taking into account more scenes. It is worth mentioning that when the Lectra 08EM-P encounters a big car, it will take the initiative to avoid it, deliberately widen the front and rear distance from the big car, and in the process of overtaking, pull the horizontal distance from the big car, reduce the parallel time, relieve the driver’s driving fatigue and pressure, and ensure driving safety.

In terms of road perception, LEEK 08EM-P supports 10 perception cameras and 5 millimeter-wave radars, and relies on centimeter-level precision maps to guide navigation. Together with two black sesame intelligent Huashan A1000 chips with a cost-effective ratio of up to 116 TOPS, it realizes the algorithmic arrangement of road environment and helps vehicles realize the intelligent driving performance of L2+ high-order parking.

Whoever ignores security is the enemy of users.

Consumers want cars with lower prices, but irrational price wars will only harm the interests of users in the end. Some brands take the lead in setting off price involution, which seems to be more cost-effective. In fact, they cut corners on invisible core components and car-making technology, and use iron oil tanks, ultra-thin and ultra-short front and rear anti-collision beams, and chopsticks-slender chassis suspension, which bring great hidden dangers to the safety of the whole vehicle. Such cost-effective is not the price that users want, and such brands can also be regarded as the enemies of users.

In sharp contrast with such a brand model, the price of the Lexus 08EM-P, which is already quite ahead in terms of three-electric system and intelligence, starting from 179,800 yuan may not be cheap, but it is also within the reasonable price of high-value plug-in SUV. Crucially, LEEK 08EM-P is a benchmark in vehicle safety.

The LEICK 08EM-P is made of thermoformed steel with the maximum pressure of 2000MPa, and the proportion of high-strength steel and aluminum alloy in white body is as high as 75%. It is equipped with aerospace-grade 7 series aluminum alloy front crash beam, and the integrated thermoformed boron steel door knocker and superelastic honeycomb filling technology are adopted for the first time, which can alleviate more impact energy, and the performance of materials exceeds that of brand luxury cars.

In addition, the car is equipped with an extended head air curtain with a length of 2000mm, which runs through the ABC column and covers the whole window area. After bouncing off, the pressure can be maintained for 6 seconds, which brings longer personnel protection. Adding 120L super-large passenger airbag can further ensure the safety of the passenger’s head. Finally, in terms of battery safety that people are most concerned about, Linke 08EM-P adopts the first integrated DP1180 bottom guard plate with the tensile strength of 1200MPa, which far exceeds the safety standard of the national standard, and can realize 50ms high-voltage power failure due to collision and bid farewell to the natural danger of battery fire.

Based on its solid performance in safety, LEEK 08EM-P obtained the first domestic certification of "60km/h side impact protection of new energy passenger cars with superimposed side pillars" issued by China Automotive Research Institute.

Jianghu car review:

In the just-concluded platform test, the Lectra 08EM-P stood out among 35 models, and won the first lap time of SUV with 2 minutes and 19.87 seconds, which fully reflected the excellent handling performance of CMA Evo architecture. The 2025 Lectra 08EM-P is not the first model of Lectra 08EM-P. Since it was launched one year ago, the cumulative sales volume has exceeded 80,000, and its high-value travel quality has been recognized by users. Its brand, Linke, also rolled off the production line for the millionth vehicle in less than six years, becoming the fastest high-end automobile brand in China and the truly recognized high-end automobile brand in China. The Lexus 08-EM-P, which is built with heart, advanced technology and solid materials, is a high-end new energy SUV choice that most people can’t avoid.
