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

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

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

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

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

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

As always, thank parents for their consent before sharing.

01

Case 1

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

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

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

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

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

Through this case, we can draw the following conclusions:

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

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

Why is there a false positive?

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

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

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

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

02

Case 2

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

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

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

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

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

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

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

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

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

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

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

Through this case, we can draw the following conclusions:

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

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

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

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

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

03

Is home nucleic acid testing accurate or not?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

　　70 years of hard work, 70 years of change, 70 years of ambition.

　　Artists bathed in the bright morning sun, embraced the fields of hope, felt the leap of the times, and couldn’t help calling: All days, all days come, let me weave you, weave you with the golden thread of youth and the wreaths of happiness! I want to dedicate the most beautiful songs to you, my mother and my motherland!

　　With love for the motherland and sincerity to the people, artists not only jump and sing on every branch like birds, but also soar from the sky like eagles. They sing about the great times, the beautiful life and the most beautiful strugglers.

　　就这样，70年光阴化作一首深情的歌，一支蹁跹的舞，一幅多彩的画，一句动人的诗。岁月如歌，歌也浓缩了岁月。

　　在举国欢庆的幸福时刻，艺术家们向伟大祖国献上最崇高的敬意和最真诚的祝福！

　　——编者

　　见证历史 再创美好未来

　　1949年，我参加了开国大典群众游行。随后，作为中央美术学院一年级学生，我根据开国大典之夜人们在天安门前提灯游行的情景，创作了有生以来第一幅作品《新中国的旗帜升起来了》，这幅作品还获得学校创作竞赛奖。从那时起，在国家培养下，我逐渐成长为一名油画家，融入新中国油画艺术发展进程，参加和组织很多重要活动、重要工作。

　　新中国成立以来这70年间，因为国家重视、画家进取，油画家队伍迅速壮大，艺术水平大大提高。如今，中国油画已成为新中国美术事业中一支重要力量，广为人民所喜爱，也受到世界各国观众和评论家高度评价和热情赞扬。在庆祝新中国成立70周年之际，我为我们国家在各个领域取得的伟大成就感到自豪，衷心祝愿我们的祖国一天比一天更加繁荣富强！

　　(Zhan Jianjun, painter, professor of Central Academy of Fine Arts)

　　Concentrate on creating and telling the story of China

　　This year is my 60th year as an artist. I caught up with the good times, and the cultivation of the party and the country made me grow from an ordinary folk artist’s son to a new China folk art professional actor; It is the audience’s love for storytelling, which makes me feel the unremitting motivation to do this career well. Today, I am full of gratitude, thanks to the party, thanks to the country and thanks to the audience.

　　Since the founding of New China, China’s Quyi has made great progress. Quyi people have changed from folk artists to new China literary and art workers, and their social status has been greatly improved, becoming an important force in the construction of socialist spiritual civilization.

　　On the occasion of the 70th anniversary of the founding of New China, as an old actor who has been an artist for 60 years, I sincerely wish the motherland prosperity and development. As a Quyi actor trained in New China, I want to write more books, speak more books, tell the story of China in the form of storytelling, and do a good job in the promotion and inheritance of Chinese excellent traditional culture; I also want to sum up the experience of storytelling creation and performance, arrange excellent bibliographies for future generations, train storytelling talents, and contribute to the development of Quyi.

　　(Liu Lanfang, storyteller, former chairman of Chinese Quyi Artists Association)

　　Create with passion and describe the times.

　　As an artist, how lucky I am to share the same fate with New China!

　　This year marks the 70th anniversary of the founding of New China. Personally, it is also the most memorable year in my life: at this time 40 years ago, I started to create the oil painting Father. At that time, the most simple and sincere initial intention was to pay attention to reality, reflect life and describe the largest field of China society — — Rural areas and the largest groups — — Farmers.

　　As the first batch of art students to study abroad after the resumption of the college entrance examination, I have the honor to witness the historical process of China’s reform and opening up for more than 40 years; I am fortunate to learn from China’s history, culture and tradition, and at the same time learn from the rich resources of global art history in the era of opening up the country and facing the world; Fortunately, while taking root in China’s real life, it is also in line with the era of globalization … … It is this background of the times that has made our generation of literary and art workers so that we can use our creativity and imagination to write footnotes for the times with our own brushes.

　　It’s the 70th anniversary of the founding of New China, and I hope I can make more and better artistic creations to present my motherland!

　　(Luo Zhongli, painter, Professor sichuan fine arts institute)

　　Start from me and build a beautiful home together.

　　In the 1990s, I went to Hollywood to film, where no one knew me. They would ask "Who is Jackie Chan", and few of them had seen China movies, let alone understood the development of China. After more than 20 years, great changes have taken place in China. Take China’s films as an example. Now many countries value China’s film market and respect China’s filmmakers, because we are supported by the great China people and the increasingly powerful motherland. Film is the language of the world. Chinese filmmakers are knowledgeable and broad-minded. Through cooperation and strengthening research and development, the future of China films is limitless.

　　China has a population of nearly 1.4 billion, and it is the best patriotic action for everyone to do their job well. Before Hong Kong’s return to China, I was making films to promote China culture. Now, I am doing all the work in cultural relics protection, environmental protection and poverty alleviation, hoping to play a role. Just like that song: "China is my country, home is my home, I love my country, I love my home!" " I love my country, we should join hands to build a beautiful home!

　　(Jackie Chan, film and television actor, vice chairman of China Film Association)

　　The era of singing calls for new miracles.

　　The establishment of People’s Republic of China (PRC) is one of the most important events in the 20th century. It rewrote the historical process of world development, completely changed the fate of people of all ethnic groups in China since modern times, and made our nation stand in the east of the world after countless hardships and vicissitudes. As a poet who lived and grew up in the embrace of this great country, my works have been marked with distinct Chinese culture since I wrote my first poem. My poems have always been linked with the land, rivers, forests, mountains and endless sky of the motherland. I will always praise and sing the industrious, simple, kind and intelligent people in this land. This great country, composed of 56 nationalities, is creating one great miracle after another in human history. As a poet, I am fortunate to live in such a new era. The vivid practice of the people to create a better new life has provided us with unlimited possibilities for writing new epics. The poet should not only be a witness but also a participant in this glorious cause that the people of China are engaged in. More importantly, he should use his poems to record and praise this era that has created miracles and will continue to create miracles.

　　更上层楼 迎接新的辉煌

　　1949年，“解放区的天是明朗的天”处处响起，然后是“五星红旗迎风飘扬”的歌声唱遍神州。10月1日，我敲着腰鼓来到天安门广场，当阅兵开始的时候，我再一次告诉自己，“这是我们的军队，我们的共和国！”

　　中国共产党是个为人民谋幸福的党，中华人民共和国是个朝阳般求新求发展的大国！70年生聚，70年经验，70年奋战，人民的奋斗创造了历史奇迹。今日之中国，已经是日月新天，日益振兴，中国梦正在变成人民共和国的现实。

　　新中国70年是人民的70年，也是我的成长、我的坎坷、我的努力、我的50卷1800万字作品的70年。新中国70年，就是我的主题，我的激情，我的歌唱，我的纪念，我的祝愿！

　　此刻，更让人想起先行者们破壁图强、以血荐国的初心。梁启超先生说：“空言爱国，无救于国，若思救之，必藉人才。”孙中山先生说：“革命尚未成功，同志仍需努力。”鲁迅先生说：“我以我血荐轩辕。”毛泽东同志吟咏的是：“春风杨柳万千条，六亿神州尽舜尧”！

　　最高领袖总书记指出：“我们要以识才的慧眼、爱才的诚意、用才的胆识、容才的雅量、聚才的良方，广开进贤之路”。

　　70年成就辉煌，未来更上层楼。聚才进贤是重要保证，也是我对伟大祖国的祝愿。

　　（王蒙，作家，原文化部部长）

　　团结实干 成就伟大复兴

　　每到国庆，心中都会生出一种美好的家国情感。我珍惜和深爱我的祖国，因为我伴随着新中国一起成长，我的命运与新中国历程已经融为一体。我关切着国家，更关切国家的未来。我对未来充满信心。

　　In the past 70 years, I am proud of the strong vitality and lasting and unique charm of our national culture, proud of the tenacity, diligence, enterprising and endless creativity of our people, and moved by every outstanding new achievement of our country today.

　　I am over 70 years old and still full of passion for life. I would like to do more work for children’s tomorrow, tell them the essence of traditional culture and encourage them to carry it forward. As an intellectual, I am responsible for the healthy development of society and the progress of civilization, and I will spare no effort to do so. Only by uniting and working hard can we usher in the great rejuvenation of the Chinese nation.

　　(Feng Jicai, writer and painter, Dean of Feng Jicai Institute of Literature and Art, Tianjin University)

　　Strengthening academics and boosting literary and artistic construction

　　Systematic research and comments on modern literature began after the founding of New China. Yaoyao’s Draft of China’s New Literature History is the foundation work in this field. After the reform and opening up, we "green peppers" dare to write Thirty Years of Modern Literature in China, which is also driven by the tide of ideological emancipation. I think it is really emotional.

　　Over the past 70 years, this discipline has always been advancing, linked with the national destiny, and now it has extended to the study of contemporary literature, forming a relatively mature discipline pattern and making outstanding contributions to university literature education and contemporary literature creation. 70 years of wind and rain have cultivated the discipline’s character of "stressing" and "grounding", and it is following the drums of the People’s Republic of China and embarking on a new journey of literary and artistic construction.

　　锻造文学 提升文明高度

　　文化是立国之本。

　　我从童年开始用汉字阅读，青年时代开始用汉语创作，我对“祖国”一词有真切的认同感。汉语是流淌于华夏土地几千年的天然乳汁，我的心灵所需要的所有养分，都是由她一滴一滴、一个字一个字喂养给我。汉语是我的精神文化之母，倚仗她的抚育和教诲，我得以自立成人。我用母语写作，在写作中度过我的大半生。我要把我的母语编成故事、变成人物、化成情感，回报我的读者们——所有读者都是我的兄弟姊妹。

　　文学和语言的命运也反映国家命运。新中国成立70年来，文学书写与新中国一起，经历曲折发展、不断更新的多个阶段，文学作品语言越来越鲜活、真实、生动，显示着我们文明程度正在不断提高。

　　（张抗抗，作家，中国作家协会副主席）

　　稳中求进 继续乘风破浪

　　新中国迎来70华诞，我们这一代人见证伟大祖国繁荣发展、日新月异。从新中国成立初期艰苦奋斗、筚路蓝缕，到改革开放后开拓创新、蒸蒸日上，中国迈向前进的每一个步伐，都凝聚着中国共产党的智慧与气魄，都饱含着亿万中国人民的勤劳与拼搏。

　　Under the correct leadership of the CPC Central Committee with the Supreme Leader as the core, all the people of China rolled up their sleeves and worked hard to overcome difficulties and deepen reforms, so that China, the great ship of the East, could ride the wind and waves and make progress steadily! In order to realize the "Chinese Dream", hundreds of millions of people in China are striving for a new era and welcoming the great rejuvenation! Bless the great motherland for its new glory!

　　(Gong Hanlin, actor of China Radio Art Troupe)

　　Sharpen art and promote national integrity

　　On the occasion of the 70th anniversary of the founding of New China, as a Peking Opera actor who has been an artist for 47 years, I am filled with emotion. The establishment of New China 70 years ago was a new life for Peking Opera, and Peking Opera also participated in and witnessed the vicissitudes of New China 70 years ago.

　　Our generation of Peking Opera people grew up in the new China, and walked with the reform and opening up. Our life choices and the road to art are closely related to the national development and reform, and our destiny is shared. The reform and opening up have strengthened our development path of Peking Opera, and the rapid economic and social development has brought us dignity and honor. The policies and measures to carry forward China’s excellent traditional culture have prompted us to continue to inherit and innovate, and the persistence and advocacy of cultural self-confidence have spurred us to push Peking Opera to the world. Looking forward to the future, Peking Opera will certainly play a more important role in the historical process of the great rejuvenation of the Chinese nation. We Peking Opera people will also integrate into the great era and into the historical torrent with excellent works that eulogize patriotism and promote national integrity.

　　(Yu Kuizhi, actor of China National Peking Opera Theatre)

　　The official Tik Tok account of Ne Zha’s orthodox sequel "The Devil’s Child in Nezha" has been officially launched recently, which may imply that the film will be announced in the near future.

　　Today, the topic of "Nezha 2 is coming" also appeared on a hot search in Weibo, which caused many netizens to discuss it hotly. Some netizens said, "It’s finally coming, and I’m looking forward to it. I’ll graduate from my sophomore year to my senior year." "My lotus root cake will meet again." "Is Nezha already a movie five years ago?" And so on.

　　It is understood that in March this year, Wang Changtian, chairman of Light Media, revealed in an internal letter to the staff of Light Media that "Nezha 2" is expected to be released next year.

　　At present, "Nezha’s Devil Children Naughting the Sea" is likely to be released in the Spring Festival in 2024.

　　It is reported that Ne Zha’s box office reached 5 billion yuan, making it the second film to break 5 billion yuan after Wolf Warriors 2. It is worth looking forward to whether Nezha 2 can recreate the box office myth of 5 billion yuan.

　　It is worth mentioning that this year’s National Day movie "I am the Return of the Hero of Nezha 2" caused many netizens to vomit, mainly because many people thought it was a sequel to Ne Zha, but after watching it, they called it "cheated".

Speaking of it, in the eyes of most consumers, it is an out-and-out family car. Because every update is very suitable for the current car demand, its sales performance is good, and it has left the title of "sales king" in the market. In 2018, its annual sales volume reached 463,000, winning the first place in the passenger car market in China. In the past 2019, its monthly sales volume exceeded 50,000 for many times, making it a car field. However, for me, the status of the king today is not achieved overnight, but has undergone 13 transformations.

13 transmutations in exchange for 14 more mature generations.

The "civilian BMW" developed to the extreme by the 1st-8th generation sports.

In 1959, the first generation was born, but it was not called at that time. It was a 5-seat small passenger car under the name of "BLUEBIRD". It used a 4-cylinder 1.2-liter engine and conquered American consumers with its brisk driving experience. The second to fourth generation Nissan uses deeper technology research and development and better adjustment ability to maximize the performance of cars. The third-generation 1.6L four-speed manual transmission model launched in 1967 officially opened the best-selling road, and its excellent suspension and excellent chassis adjustment were also called "civilian BMW" by fans. The 8th generation, which came out in 1987, has a smoother and lower profile. It is equipped with the famous ATTESA four-wheel drive system, which can provide 1.8L turbocharged power option. On the suspension system, the basic design of front McPherson and rear strut suspension is adopted, and the body weight is optimized. The sports performance can be described as the ultimate development.

9 th -11 th generation technology armed to teeth

The ninth generation and the tenth generation focused on the configuration of science and technology. At the turn of the century, the ninth generation achieved great success with the "E" configuration as its selling point. At that time, the car was equipped with mobile hands-free phone, intelligent rearview mirror and HUD, which could project the speed on the corner of the front windshield. It was full of science and technology. After the tenth generation, e-devices were further increased, including satellite navigation, reversing image monitoring, car video/audio and car phone Bluetooth, which can be said to arm technology to the teeth.

The 12th-13th generation opened the era of sedan chair king.

In 2006, the 12th generation entered the China market with the concept of "entertaining family members", which set a brand-new benchmark for car models in comfort and economy, and at the same time brought out the title of "Nissan Big Sofa". By 2012, the 13th generation went on the market, achieving an overall improvement in technology configuration, and meeting the needs of families in the new era with more humanized and practical intelligent configuration.

The 14th generation of comprehensive innovation continues to be king.

The 14th generation has become an "ideal car for a new generation of families". Relying on the advantages of Nissan CMF super modular platform, the product strength has been improved in an all-round way. The appearance adopts the latest V-motion 2.0 design language of the family, and it adopts a slip-back shape, which is handsome and compelling. At the same time, it also reaches the low drag coefficient of 0.26Cd of the GTR level of Nissan super sports car, which reduces the air resistance by 14% compared with the previous generation. The central control design and intelligent technology have been greatly improved, and you can still feel the taste of home when you sit in it, but with a little more technology, the unique IFCW over-the-horizon collision warning at the same level, EAPM accelerator misplacement correction, IDA intelligent fatigue driving warning system and IDM intelligent highway stability system have not been compromised in space, and the comfort of the rear seats is still satisfactory. The power part is equipped with the brand-new 3rd generation HR16 intelligent engine, which highlights the four cutting-edge engine technologies, and emphasizes that the advantages of the whole powertrain are economy and stability, and the fuel consumption of 4.9L/100km is comparable to that of hybrid vehicles.

Summary:

The king is never achieved overnight. From 1959 to 2019, every generation always faces every consumption evolution, and builds family cars that conform to the times according to the needs of users and their own cutting-edge technology, thus bringing the best partners to every family, climbing from 80,000 units/year to 470,000 units/year, and winning the "2018 China Auto Market Championship". As of April this year, domestic sales have already been achieved.

When the car is constantly pursuing more seats, it shows a different side in the market segment. In the same spacious carriage, the less, the more advanced the product positioning. Therefore, in some mid-to-high-end products that have been or will be listed in the near future, many products are not limited to launching regular 7-seat models, and fewer 6-seat or even 4-seat models have begun to be welcomed by consumers.

In the new generation of product planning, there are three versions of 7 seats, 6 seats and 4 seats. At present, the main models on the market are 7-seat models, even the GL8 Avenir Avia models with high-end positioning are 7-seat models. However, recently, the official map of a new generation of GL8 Avenir Avia six-seat version has been officially released, which also indicates that it is a step closer to the launch of this new car.

Configuration is more luxurious than the current Avenir.

It is worth mentioning that the new generation GL8 Avenir Avia six-seat version is not just as simple as replacing the current model with two independent seats. From the seven-seat version to the six-seat version, it is obviously upgraded from the perspective of product positioning, so we see that the configuration of the new car has also been greatly upgraded from the inside out, showing the style of luxury.

The new generation GL8 six-seat model is classified as Avenir Avia series, so all the unique designs of the current Avenir Avia series have been preserved in new cars, such as chain mail-style China Net and exclusive Merlot wine red. At the same time, the new car has also been upgraded. At first glance, the new car is equipped with a brand-new Matrix all-crystal diamond headlight composed of eight "diamond crystals". This upgrade not only improves the visual effect, but also realizes eight intelligent lighting modes in actual lighting function. In addition, ADB’s anti-glare high beam function has 18 high beam lighting zones, which cooperate with high-definition wide-view forward camera to help improve driving safety at night. As an echo, the taillight style of the new car has also become a suspended arrangement style of 11 spar, which is like a stretched wing after lighting.

In order to show luxury, the new generation GL8 Avenir Avia six-seat model also provides exclusive dynamic concierge lights with rich styles. At the moment when the electric door is opened, Avenir Avia’s exclusive welcome blanket shines out, and with Avenir Avia’s exclusive lighting welcome pedal, every boarding is honored.

Inside the car, the second row of seats is consistent with the current model with high standards. Different from the 7-seat model, the 6-seat model also provides independent seats with high comfort for the third row passengers. The seat can adjust the front and rear distance by 160mm, and is equipped with 6-speed adjustable independent handrails, 146-degree super-large chair back inclination angle, heating/ventilation function and dual USB charging interfaces.

The six-seat version is a more practical choice.

From the perspective of improving the sense of luxury, the new generation GL8 Avenir Avia six-seat model with higher positioning will obviously be better than the seven-seat model. But this is not just the only purpose of the six-seat model.

In the real use scenario, the current GL8 Avenir Avia seven-seat version can only provide the most distinguished ride experience in the second row. Although it’s okay to ride, you will never let your guests sit in the third row during business reception. However, the six-seat model is different. Although it is still slightly different from the second row, it is still equipped with many comfortable and practical configurations, which can at least realize the reception of some VIPs. In other words, the seven-seat model can only receive two VIPs, while the six-seat model can receive four VIPs, which is the practicality of the six-seat model.

If you consider more, the six-seat model can also be exempted from the annual inspection, which also makes the car more simple and worry-free.

Write it at the end

From the perspective of the new generation GL8 Avenir Avia, the author thinks that the upcoming six-seat model will be more practical than the current seven-seat model. At the same time, for the mid-to-high-end market, the launch of the new generation GL8 Avenir Avia six-seat edition will re-establish a new standard for large luxury. (Text/Zhong Yi)

　　The 21st Guangzhou International Automobile Exhibition (hereinafter referred to as "Guangzhou Auto Show") is in full swing at the Pazhou Complex of the China Import and Export Fair. On November 18, the first audience open day coincided with a Saturday, and the venue was bustling with people.

　　How to visit the auto show? How to choose your favorite vehicle? What are the highlights of the RV exhibition area? What new products and services are launched by smart cars? With these questions in mind, the reporter visited the Guangzhou Auto Show and listened to the voices of the citizens at the scene.

　　Buying a new energy vehicle or a fuel car? Citizens have different opinions

　　This year’s Guangzhou Auto Show has attracted mainstream auto brands and new energy vehicle companies from around the world. The exhibition area covers an area of 220,000 square meters, with a total of 1,132 vehicles on display, of which 469 are new energy vehicles, accounting for 40%. Various brands, rich models, preferential promotions, and diverse price ranges… Guangzhou Auto Show has attracted many citizens to come and buy their favorite models with a series of advantages.

　　In front of the Huawei Hongmeng Zhixing booth, Ms. He was listening carefully to the lecturer’s introduction of relevant technologies and products. She told reporters that she came from Shenzhen on a special trip, hoping to choose the right car here.

　　When it comes to buying traditional fuel vehicles or new energy vehicles, Ms. He said that she prefers to choose new energy vehicles out of her own considerations. "Because I am not very good at parking, I really want to know more about the function of automatic parking. In addition, intelligent driving, automatic obstacle avoidance, artificial intelligence technology, etc., are all my concerns."

　　In the field of new energy vehicles, she is more inclined to hybrid gasoline and electricity. "My budget is within 300,000, and my daily travel is mainly in the upper class and suburbs. When I am on vacation, I may drive back to my hometown. If I can charge and refuel, I will be more at ease." In addition, the car brand is also an important factor affecting Ms. He’s car purchase. "At this stage, when buying a car, I will still choose a well-known car company, and I feel that the quality and safety are more guaranteed."

　　Regarding whether they prefer to buy new energy vehicles or traditional fuel vehicles, the reporter randomly interviewed some citizens at the scene. People who intend to buy new energy vehicles often mention the following points: the price of the car is advantageous, the charging cost is lower, the model is more scientific and technological, the level of intelligence is high, and the relevant policy support; but they also mention mileage anxiety, difficult charging, and insufficient charging infrastructure.

　　Many people who choose traditional fuel vehicles mention that they prefer to use fuel vehicles, which are suitable for long-distance travel, have lower maintenance costs, and better driving experience. However, the disadvantages are that the vehicle price is relatively high, the fuel cost is more expensive, and the product update is slow, making it difficult to meet the needs of intelligent travel.

　　As the car market evolves, so do consumer choices. Mr. Cheng bought a gasoline-electric hybrid in 2017 and a gasoline-powered car three years later. "Each has its own advantages and disadvantages, and it is difficult to generalize," he says. "It is more comfortable to drive a gasoline car on high speed, but it is flatter to drive a hybrid in the city. I will definitely buy a tram in the future, but now I feel that the tram still has a lot of limitations, such as low battery life at high speed, easy to heat up when charging, and not 100% safety."

　　Different groups of people have different needs? Precise positioning of car companies

　　The competition in the car track is intense. How can car companies attract customers with high-quality products and high cost performance? At the exhibition hall, some car companies strive to attract more target customers by reducing prices for a limited time, giving discounts, live streaming, and providing customized services.

　　The needs of different groups of people vary, and automakers need accurate positioning to win customers.

　　In some booths, car companies placed camping tables and chairs, and placed bicycles on the roof to set off the product highlights with specific life scenes. Mr. Ge, who likes cycling and outdoor camping, admitted that "it is really attractive. When I see the car, I think of the outdoor camping scene. My car budget is about 150,000, and after looking around, there are many favorite products."

　　In response to the needs of some family travel, some car companies have positioned themselves as "affordable and easy to drive, comfortable space, and designed for family travel"; some car companies have proposed the concept of giving young people a more ideal "home"…

　　There are also some car companies that are ingenious and choose more niche tracks. For example, GAC Trumpchi launched the E9 Care Edition, which is equipped with electric welfare wheelchairs to facilitate the travel of the elderly, pregnant women, the disabled and other groups.

　　"This kind of innovation is really practical and humanistic," said one of the elderly on the spot. "My parents are old, and it looks good to buy this car to take them around." In this regard, a staff member of GAC Trumpchi said that the car is still in the research and development stage and is expected to be mass-produced next year.

　　Sense of technology, practicality, intelligence, personalization… At the Guangzhou Auto Show, a dazzling array of products with different positioning made the public feast their eyes. "I have been to the Guangzhou Auto Show before, and I can clearly feel the increase in the number of new energy vehicles this year. The exhibition areas of Tesla, Ideal, Xiaopeng, BYD and other new energy vehicle shows are quite cool, and the level of intelligence of the cars is also surprising. Especially the release of some concept cars makes people can’t help but imagine the future direction of automobile development." At the XPeng Motors exhibition hall, Mr. Wang, a veteran car fan, looked at Xiaopengfei’s driving suspended in the air and said.

　　At the scene, many citizens passing by the exhibition area took a group photo with the car, and some people expressed their imagination of "technology changes lives, where to go in the future".

　　RVs are expensive and can’t afford them? 300,000 or 400,000 also have options

　　When asked, how do you feel about coming to the Guangzhou Auto Show to see an RV? Many citizens invariably mentioned that the price of an RV is cheaper than expected, and there are many options for 300,000 to 400,000 yuan.

　　"I used to think that RVs were expensive and only existed in other people’s beautiful travel lives in swipe short videos. But today I came to the RV area of the Guangzhou Auto Show and found out for the first time that I could buy an RV 300,000. My friends and I just went up to experience it, and it was very comfortable. I never had the idea of buying a car before, and this moment was ignited." Ms. Wang, who is in her 30s, said with a smile.

　　Another couple echoed similar sentiments. Mr. Chen, who brought his girlfriend to the show, said: "I didn’t have the opportunity to see so many models before, but today I was really amazed. The price of the RV broke my stereotype." His girlfriend couldn’t help but sigh, "I don’t even want to buy a house with an RV. If the relevant infrastructure can keep up, that would be great."

　　At the scene, Dade RV, Yutong RV, Jiangwei RV, Great Wall RV and other brands displayed a variety of highly competitive products. According to the relevant person in charge of Yutong RV, from more than 80,000 yuan to more than 1 million yuan, they have launched different grades of RVs to meet the differentiated needs of the market. Among them, 400,000 and 500,000 yuan sold more. "Retirees and freelancers buy most of them, they have more free time and like to travel outdoors."

　　A retired couple is sitting in an RV to experience the comfort of the driver’s seat. They also checked the size of the bathroom, the size of the bed board, the length of the water pipe, the size of the water tank, etc. Aunt Huang told reporters that she and her husband have been "playing with RVs" for many years and recently plan to replace them with a new RV. "With an RV, you can travel freely, and you can have a home wherever the car is, and life is full of fun." However, Aunt Huang also recommends that you think carefully before buying a car. Do you really need it? Do you have time to travel? Can you accept problems such as parking difficulties and water and electricity supply troubles? If you just want to experience it, renting a RV is also an option.
