From the appearance, it incorporates many mature design elements. Generally speaking, the front design of the new generation Cadillac CT5 has become more simple and atmospheric, and some protruding lines have been added to the hood, which looks quite muscular, with sharp headlights on both sides, and the internal light groups are patchy and bright when lit. From the waist line, the new car adopts the design that looks like the side, which lengthens the visual effect of the car to a certain extent. The rim shape is atmospheric and the visual effect is acceptable. At the same time, Founder’s tail shape echoes the front, and the split taillights of the new car are more exquisite.

The interior of Cadillac CT5 is full of luxury and layering. The new car is also equipped with three models of Cadillac’s latest style, and it is also equipped with shift paddles, which is very fun to drive. In the center console and the door handle, a lot of plastic and leather materials are used to cover and wrap it, which is rich in touch. It is equipped with a 10.0-inch center console suspended LCD screen, which is clear in display and trendy in design. The front row is also equipped with a dual-temperature automatic air conditioning control system to freely debug the most comfortable space atmosphere. Leather seats give passengers just the right support and a soft and comfortable touch.

The length, width and height are 4930×1883×1445mm respectively, and the wheelbase has reached 2947 mm. In the same class, the wheelbase of Cadillac CT5 ranks third. As a medium-sized car, its body size does not occupy much advantage in its class, and its internal seating space is only basically enough. After all, it is limited by the length and shape of the body. The design of skylight also increases the subjective space feeling of front and rear passengers. Among the models of the same price and class, the trunk volume of Cadillac CT5 ranks 9th. The space is relatively regular, without obvious protrusions, and the overall loading capacity is good.

Recently, Harvard University announced that starting from the fall semester, the self-developed language model CS50 Bot will be used as the teaching assistant of the popular course Introduction to Computer Science, so the new students will become the "first batch to eat crabs". This move has caused heated discussion on the Internet, and some people worry that AI will undermine students’ motivation to learn; Professor Harvard said that AI teaching assistants can alleviate the real teaching dilemma and improve the learning experience.

Wen, Luna, Jennifer

Since last year, the popularity of the AI topic has not diminished. However, it is still surprising to see that Harvard will "hire" AI in the ace elective course: "Has the application of AI evolved so fast?"

The news came from Harvard Crimson. David Malan, the lecturer of CS50 (Introduction to Computer Science), confirmed that this course will start from the autumn semester, and AI will serve students with 50 Course Assistant and Teaching Fellow (TF is a more advanced teaching assistant than CA).

The headline of Harvard Crimson &Malan’s Twitter response

The AI used this time is not the familiar GPT-3.5 or GPT-4, but a language model CS50 Bot developed by Harvard itself. It will be responsible for answering some common questions in the course, giving suggestions for revising students’ homework, and answering students’ questions at any time outside the working hours of other teaching assistants.

The CS50 course, in which AI is a teaching assistant, is a popular course at Harvard. In the past decade, the number of students enrolled in the course ranges from 500 to 800 each year. There are even students from other majors who have switched to computer science or engaged in related work in this major after finishing classes.

CS50 Statistics on the number of students who choose courses every year

Such a popular course, when Harvard has not launched a complete educational application scheme for AI, directly introduces AI teaching assistants, which makes people sigh, "How dare Harvard!"

The hot discussion on the Internet also has different ideas:

Some people think that the function of AI is too powerful, and worry that this is the beginning of AI replacing human beings?

Some people also question the ability of AI, and ask Harvard that the annual tuition fee is as high as $50,000. Is it fooling students with AI?

Some people also worry that AI will make students no longer motivated to learn, and even completely subvert human cognitive development.

So, as one of the representatives of the top universities in the United States, what does Harvard applied AI assistant think? What kind of thinking does Harvard have in the face of all kinds of doubts about the AI crisis?

Harvard’s hottest CS50 also has bad reviews.

AI teaching assistants are here to "put out the fire"

Will AI replace human teachers? This is the first reaction of many people after seeing Harvard news.

However, if you look through the report in Harvard Crimson, you will find that CS50 Bot, the teaching assistant, is more like "fighting fire" than replacing human teaching assistants and professors.

On the one hand, Malan, the lecturer, has always positioned CS50 Bot as a learning tool for students, and never mentioned that Bot should be the lecturer. Even as a teaching assistant, Bot is "inferior", and its advice can only be considered "accurate" after being confirmed by other teaching assistants.

On the other hand, Malan urgently hopes that AI can improve students’ learning experience, so that this big class of nearly 1,000 students can also provide 24-hour one-on-one tutoring. In the past, this was an impossible task.

Professor Malan gave a lecture on Introduction to Computer Science.

Malan is not only planning a large-scale AI test, but also considering the dilemma of real teaching.

In many people’s impression, Harvard’s ace course has its own aura-in the YouTube recording of CS50, David Malan stood on the spacious stage of Sanders Theatre and explained those complex computer concepts like a drama.

If you are lucky enough to study at Harvard, you will also know that this course also has a huge teaching assistant group to provide reference materials and homework guidance for students.

But in March this year, another report in Harvard Crimson, Undervalued, but Highly Utilized, revealed the bitterness behind the brilliance of these large-scale introductory courses.

The Harvard Crimson Report on Teaching Assistants

"Professor Malan gave a wonderful lecture on the stage, but other studies depend on teaching assistants." Fernandes, a former CS50 teaching assistant, expressed his opinion. "In essence, it is the teaching assistant who propped up this course."

Managing the professor’s office hours, leading small tutoring and attending weekly staff meetings are still reasonable jobs for teaching assistants. Nowadays, they have to answer questions for a long time after class and prepare most of the course materials.

These burdens have far exceeded the provisions of the school agreement-teaching assistants can be paid up to 10 hours a week, and course assistants can only calculate up to 4 hours. According to this standard, Fernandes leaves only three hours for homework review every week. Even if there are dozens of people in the teaching assistant group, each person is too busy for three hours.

Leggett, the current teaching assistant of CS50, added a "slot": "The teaching assistant has to support the exhibition of CS50′ s works, but often the day after tomorrow is our own final exam of advanced computer science. The agreement never mentioned this time conflict, and the consequences can only be borne by ourselves."

In this case, CS50 is no exception. Introduction to probability and comprehensive introduction to life science are all the same.

In addition to the dissatisfaction of the student teaching assistants, the students of elective courses also suffered a lot of "dumb losses".

Harvard’s admissions website reads, "As world-class educators, professors work side by side with students to encourage them to look at problems with new eyes." However, many Harvard students feel that they are just the audience who listen to the professor’s lectures. If you really want to say that students work side by side, it is still the teaching assistant.

"Although it is indeed possible for students to have direct contact with some of the greatest scholars in the world, this opportunity is much smaller than it seems." "Harvard Crimson" commented.

What’s more, teaching assistants are students after all. No matter how much they love their subjects, there is a real gap between them and professors in knowledge, thinking and teaching.

Some students who have taken the introductory biology course complain that the teaching assistant knows a lot, but the level of counseling is worrying, and she can’t paraphrase complex concepts into expressions that she can understand. Finally, she is left to recite and memorize.

There are also teaching assistants who are limited by knowledge storage and understanding, and their opinions are contradictory to those of professors, which is simply worse for students who have doubts.

Kyle Waldman, who is studying for a doctorate, said that unless it is a small class or the students themselves are extroverted, it is "difficult for professors to interact with students continuously". Compared with smaller schools, Harvard students are "disadvantaged".

Students want more counseling, teaching assistants call for less work, and professors find it difficult to find a balance between research and teaching. The contradiction between students’ needs and the cost of manpower and time is becoming more and more prominent.

Since students cannot be banned from using AI,

It’s better to "turn an enemy into a friend" and take advantage of AI.

Malan asked AI teaching assistants to "put out the fire", so the way of using AI is also more "radical" among Harvard professors. But in fact, this is already slow.

Students’ hands and feet are faster than professors’ countermeasures. At the end of last year, just after ChatGPT came out of the circle, there were Harvard students driving ChatGPT and taking online open-book exams, and it was not a case.

It was not until late January that the email from the undergraduate education office arrived late, asking teachers to pay attention to the influence of ChatGPT, but no specific regulations were given, and the decision-making power was handed over to teachers.

Most professors in Harvard have a negative attitude towards the influence of AI technology, so many classes are forbidden to use ChatGPT, such as religion, Spanish and physics.

More teachers realize that it is impossible to ban it completely, so they try their best to reduce students’ chances of using ChatGPT and push them to learn by themselves.

Previously, the main assessment of French classes was done in the classroom, which restricted students from using Google Translate as a tool. After the popularity of ChatGPT, Amanda Gann, a lecturer, changed the final evaluation to "paper+dialogue", asking questions at any time to prevent students from writing a draft in advance with ChatGPT.

Gann admits that if it weren’t for ChatGPT, oral evaluation wouldn’t have such an important position as it is now. This also inspired her to reflect on her homework: "Is this something that only humans can do?" "How to make students not want to use AI to complete it from the beginning?"

As heroes think, so thought Bruce. Boaz Barak, a professor of computer science, also made homework and exams more difficult.

In the past, writing a simple neural network code was enough to complete an assignment; But now, students should reproduce a more complex code inspired by cutting-edge research. "Since students have access to more advanced tools, I naturally have to ask for more."

Professor Maria Dikcis of "English: The Dark Side of Big Data" went one step further and encouraged students to use ChatGPT critically. In her homework, she tried to make students compete with machine intelligence: the students wrote a short analysis article first, then generated a paper on the same topic with ChatGPT, and then compared the two articles. She hopes that students can see the shortcomings behind the brilliant appearance of AI and think about the significance and value of these shortcomings.

In contrast, the AI teaching assistants of CS50 have a feeling of "turning enemies into friends". Teachers are worried that students use AI because ChatGPT is so easy to use, so it is better to use this in turn and make AI a 24-hour online teaching assistant.

This idea is also in line with the personalized learning experience that Malan has been exploring. In order to keep students with different levels interested in CS50 all the time, Malan and teaching assistants designed assignments with different difficulties.

Statistics of Students’ Learning Feeling in CS50 Course & Hierarchical Homework Design

For example, students with weak ability to design filters for pictures can write a black-and-white filter, while students with strong ability can challenge the filter of film negative+reverse color.

Students of different levels can freely choose the difficulty of homework.

But the problem of students has been solved, and the time contradiction of teaching assistants still exists. They spend a lot of time commenting on homework. It takes less than 14 seconds for students to read the comments. After revision, it takes a long time to get a reply. "This is not an efficient way for teaching assistants and students to use their time." Malan said.

And the convenience of AI is like the missing piece of puzzle. Therefore, Malan makes AI teaching assistants undertake a lot of procedural and repetitive work. Although the revised opinions of AI teaching assistants still smell like robots, they hit the nail on the head to find the problem and give a detailed explanation, but they also got the evaluation of "weirdly informative".

CS50 Bot under test

AI teaching assistant is a large-scale technical test, and it also shows students how to use AI reasonably. After that, Malan also hopes to integrate AI technology into other STEM classes and even humanities classes, bringing some changes to teaching.

Be the master of learning or the puppet of technology?

AI is a sword of Damocles.

However, the change of teaching methods still seems to be unable to solve a question-AI is coming, can human beings hold their ground and not be replaced?

The experience of Steven Pinker, a psychology professor at Harvard University, is a very intuitive answer:

As the speaker of the introductory psychology course, he was once worried that ChatGPT was strong enough to take his place until he discovered the cognitive difference between AI and human beings.

"I asked ChatGPT,’ If Mabel is alive at 9 am and 5 pm, is she still alive at noon?’ We all know that once a person dies, he can’t be resurrected, but ChatGPT replied,’ There is no information to clearly indicate whether Mabel is still alive at noon.’ It can be seen that AI does not grasp the basic facts of the world operation and lacks common sense and logic on which human beings depend. "

"Human memory and computing power are limited, and it must be admitted that AI is stronger in retrieving a large amount of information." Pinker said, but AI’s "cognition" comes from the collection of massive information, and it has not developed logical ability, which is completely different from human beings.

Steven Pinker said in an interview with Harvard Gazette.

It can be said that thinking ability is a unique advantage of human beings, and logical ability is only one of them. Whether students can exercise various thinking abilities in their study determines the result of "confrontation" with AI. On this issue, Harvard professors also emphasized the weaknesses of AI thinking ability.

Lack of critical thinking is another obvious weakness of AI at present.

The MIT Science and Technology Review issued an early reminder that because there are a lot of biased and hateful languages on the Internet, AI as a training set will further amplify these prejudices.

In addition, generating false content has always been an obvious problem for AI. In March of this year, experts from NewsGuard found that GPT-4 responded to false news 100%, and GPT-3.5 could reply to at least 20% of false news that "these statements are groundless".

NewsGuard’s report on GPT-4

In addition, GPT-4 is less "good" at programming than before, and the introduction of AI teaching assistants on CS50 has also caused some doubts. Malan himself predicted that AI teaching assistants might "occasionally perform poorly or even make mistakes" at the beginning.

However, he believes that this is precisely the opportunity for students to exercise their thinking ability. He tells students that "when receiving information, whether it is from AI or human beings, we must always think critically. Identify the authenticity of the information, evaluate the credibility, and then decide whether to accept the other party’s information. "

The ability of reasoning and thinking is also the weakness of AI, although it is very confusing.

Some students use ChatGPT to summarize the general idea of reading materials, and its word-for-word output makes people feel that it is really thinking. But is this really the case?

Soroush Saghafian, an associate professor of public policy at Harvard’s Kenny School of Politics, called this a flaw in AI. "People think that AI can think, reason, and even think that it is omnipotent, which is the result of commercial speculation."

Frankle, the chief scientist of MosaicML, an artificial intelligence startup, also verified this statement: "The purpose of developing AI by startups has always been to build a great language model product, rather than publishing and sharing knowledge, which is only an incidental effect."

Saghafian believes that students should actively interact with ChatGPT, but also understand the disadvantages of AI itself. "At that time in 2000, teachers taught students to understand the shortcomings of search engines like Google in thinking, and now they need to treat ChatGPT as well. Students should understand the difference between reasoning and simply outputting content. "

Where does human thinking ability come from? It must be in the process of learning. However, when high scores and GPA are especially needed, students will inevitably use ChatGPT to be lazy. Even Harvard professors have limited means to use, and the decision to study is ultimately in the hands of students.

Nevertheless, Harvard University and professors try their best to inspire students:

Harvard calls the meaning of learning the value of intellectual transformation.

"It will be difficult to change yourself. To learn the principles of quantum mechanics or to understand the society before the industrial revolution, we need to deconstruct and reconstruct our world view. Therefore, Harvard University not only emphasizes academic ethics, but also expects students to experience this difficult process. "

John Hamilton, a professor of German and Comparative Literature at Harvard, said something more profound:

Technology has broken all kinds of restrictions and made our life easier and more convenient. We can fly across the world, scan literacy maps, or search keywords in Google to learn anything. However, what can give us meaning in life is limitation.

If there is enough gold, we won’t care about it; If we can live forever, we won’t care too much about life. Our concern comes from our limited ability. Life without limits will eventually be worthless.

Cards folded from thick paper on the top cover of cigarette boxes have become new toys for primary and secondary school students. Children put their hands together and beat the ground with their empty palms. These rectangular cards, called "smoke cards", won even if they were hit by the palm wind, and became a popular game. Cigarette cards have even become social tools for some children.

What is the magic of "cigarette card" to attract a large number of primary school students? For parents and schools, how to "cut off the card" is more worthy of attention.

Family "War" Caused by "Cigarette Card"

The boy Xiaojun has been playing with the "cigarette card" for a long time. How to make the child bid farewell to the "cigarette card" has caused his mother Liu Li a headache so far. "I remember the first time I found him playing, I was so angry that I tore up all his’ cigarette cards’ in front of him." Liu Li’s behavior of "tearing the card" was firm and decisive. She thought that the child would be "shocked" and then bid farewell to the "cigarette card".

But her idea was wrong. After about a month, she found Xiaojun still playing the "cigarette card" and the card was hidden in a hidden position at home. This time, Liu Li didn’t break into a furious rage in front of the children, but quietly picked up the "cigarette card" he saw and threw it away. "He must know that I threw it, and he also knew that I opposed him to play. He didn’t ask about it after throwing it away."

Netizens exposed a large number of cigarette cards from their children’s schoolbags on a certain platform, and the mother said that she was very angry.

This was finally over, but it didn’t take long for Liu Li to find a stack of "cigarette cards" in Xiaojun’s schoolbag! Time and again, Liu Li felt a little collapsed. "I really don’t know what to do. For the sake of harmonious mother-child relationship, I pretended not to see it. I have torn it, I have received it, and I have been educated as a parent. It is useless. " Liu Li also found that after playing the "cigarette card", the child’s behavior changed. "I noticed that he would imitate smoking when eating some strip biscuits."

Schools prohibit students from playing "cigarette cards" secretly.

In addition to parents, schools are also worried about playing "cigarette cards" for primary school students. Xu Yan (pseudonym), who works as a teacher in a school in Nan ‘an District, has regulations in her school that students are forbidden to bring any toys into the campus, and "cigarette cards" are also on the list, not to mention playing "card-tapping" games at school, but they still secretly bring "cigarette cards" with them.

"You can’t play in school. If the teacher sees a student playing, it will be confiscated for the first time. I have received it several times. But they will play in the neighborhood near the school after school, and several times they see students playing on their way home from work. Some shoot on the table in the community, and some simply squat on the ground. " Xu Yan said.

Another primary school teacher, Wang Ting (a pseudonym), also said that he did not allow children in the class to play, and as long as any students brought to the school, they would be confiscated. Because she found that children "shoot cigarette cards" not just for games, "some will gamble. In short, it is very bad for the losing party to agree to the requirements put forward by the winning party."

Physical and mental harm

Speaking of the harm of playing "cigarette card", Yu Chunmei, deputy director of pediatrics of Chongqing Fifth People’s Hospital, analyzed it and divided it into psychology and physiology.

Media reports of children playing with "cigarette cards" resulting in finger injuries.

In terms of health, playing "cigarette cards" is also risky. "Children are at risk of getting their hands scratched when slapping the’ cigarette card’. If it is not treated in time, it may lead to wound infection and even necrosis of related parts. If you slap your palm too hard when playing games, there is a risk of fracture of your child’s metacarpal and phalanx. The’ cigarette card’ smells like cigarettes. For children with asthma, it may cause asthma and should be avoided as much as possible. Children with allergies should also try not to contact them. If children have allergies, they may not think that the allergic source is a’ cigarette card’. In addition, children looking for cigarette cases from garbage dumps must have poor sanitary conditions, and there are also health and safety hazards, which may lead to respiratory and digestive tract infections. "

Liu Jun, a national second-level psychological counselor, believes that children playing "cigarette cards" mainly have the following five potential risks.

The "cigarette card" game is based on real cigarettes, which easily makes children mistakenly think that smoking is a normal and universal behavior, which will make children form wrong values in the process of growing up and even try to really smoke.

Second, among some students, "smoking cards" have been divorced from the game level and are being upgraded to "gambling".

Third, in the "cigarette card" game, children often compare who owns more "cigarette cards" and higher-level cigarette brands. This kind of comparison will affect their interpersonal relationship, and may make them become vain and impetuous, and excessively pursue material enjoyment.

Fourthly, because of the attraction and addiction of the "cigarette card" game, many children are easily addicted, which seriously affects their academic performance and physical health, and even has a negative impact on their psychological development, increasing the risk of behavioral problems in the future.

Fifth, the "cigarette card" game often contains the content of imitating smoking. Although it does not contain tobacco, long-term imitation of smoking may cause potential harm to children’s respiratory system and cardiovascular health. In addition, eating harmful substances on cigarette cards by mistake may also cause harm to children’s health.

Liu Jun went to the community to tell children and parents about the dangers of cigarette cards.

Parents with broken cards can do this.

How to keep children away from "cigarette cards" is a headache for parents, and Liu Jun also gives suggestions.

"Parents can look for alternative games. For example, help children develop more hobbies, such as playing ball and swimming. Encourage children to participate in some games that require innovative thinking, such as programming or scientific experiments. You can also take your children to participate in outdoor games, outdoor research, etc. to meet the different interests and needs of children. "

She also suggested that parents can also try to increase their children’s social practical experience. For example, let children participate in some scientific groups or social volunteer organizations to simulate social roles, such as simulating traffic police and firefighters, and cultivate their sense of social responsibility and practical ability. You can also make full use of social public resources and visit and study in public free places such as libraries, natural museums and science and technology museums.

Parents should also cultivate and strengthen children’s mental health education, strengthen their awareness of children’s health, help children avoid bad habits such as smoking and excessive use of electronic equipment through family rules and role models, and create a family environment that supports children’s all-round development, including physical, psychological and social adaptability.

"When implementing these suggestions, parents should adjust their methods according to their children’s age, personality and interests to ensure that the implementation of the suggestions is both effective and suitable for their children’s development needs. At the same time, parents themselves should become role models for their children and influence and educate their children through their own behaviors. " Liu Jun said.

Guide children away from cigarettes. They’re on the move.

On August 15th, Qin Qing, the prosecutor of Sister Sha from the Procuratorate of Shapingba District, Chongqing, went to the summer care class in Longtai Community, Zengjia Town, Shapingba District with a "cigarette card" and a pony Baolika, and gave a "class" to the children and their parents who are about to usher in the new semester. She asked the children in detail about the situation of everyone playing "cigarette cards" and told them about the possible harm of indulging in "cigarette cards".

"Sister Sha" prosecutor holds a "cigarette card" to explain its harm to children.

She told the children that "cigarette cards" can also lead to comparison psychology. Some children look for cigarette cases from the garbage dump and shoot "cigarette cards" on the ground may affect their health; Focusing on playing "cigarette cards" will affect learning and may lead to children’s curiosity and interest in cigarettes; The "smoke card" game may also lead to children’s gambling psychology, etc., calling on everyone to stay away from smoke cards and study hard after school starts.

Liu Jun, a national second-level psychological counselor, also made a special trip to tell the harm of children playing "cigarette cards" and how to guide parents.

This year, the Shapingba District Procuratorate also made a special trip to investigate around more than 10 primary and secondary schools in the district, and according to the results of the investigation, it delivered the pre-litigation procuratorial suggestions for administrative public interest litigation to relevant departments. Subsequently, the relevant departments launched special actions to control the sales of "cigarette cards" around the campus, such as issuing the "Proposal on Preventing Primary and Secondary School Students from Addicting to the" Cigarette Card "Game" to shops.

After consulting the relevant news reports, the upstream journalists found that the relevant departments in Jiulongpo District, Yuzhong District, Yubei District, Chengkou County, Wanzhou District and other places have taken control measures on the sales of "cigarette cards".

Yidong is a historic model of Chang ‘an, and its brand-new image gives people a brand-new feeling, which is not only in appearance, interior and configuration, but also in power. After the launch of the 1.6L model at the end of March, and the news that the 1.5T turbocharged model will be launched in the future, the relevant media recently got the spy photos of the 1.8T version of Changan Yidong model.

　　　　For the 1.6L model that has been put on the market, we can feel that this model tends to be used at home during driving, which is very valuable as a compact model with its own brand. The power output in the acceleration process is very linear, which is only enough for its vehicle weight of about 1.3 tons. During the test drive, when the speed reaches about 130km/h, the stability of the vehicle is also excellent, and there is no obvious feeling of drifting. It can be seen that Yidong’s driving performance is still good, which has laid the groundwork for the later 1.5T and 1.8T models.

　　　　Therefore, it is very exciting to launch a 1.8T model in the future, which reminds people of Volkswagen Bora and sagitar, which have both a 1.6L model for home use and a 1.8T top model for driving performance, and Changan Yidong has also taken such a route. At present, there is no more data on the power parameters of the new model, but the power performance must be good with such a displacement and an escaping body.

　　　　At the time when the new power went on the market, Yidong, which was listed in advance, was equipped with a Blue Core1.6L naturally aspirated engine, matching a 5-speed manual transmission. In June this year, an automatic transmission model will be launched. It is reported that next year Yidong will also launch a model equipped with a 1.5T turbocharged direct injection engine and a dual clutch gearbox. The 1.5T engine has in-cylinder direct injection and turbocharging technology, and its maximum power will exceed 120kW, so its power is very superior. It is expected that the 1.8T model may be launched at the same time as the 1.5T model, and it will also be equipped with a dual clutch gearbox.

Northbound funds bought 10.326 billion yuan in the whole day, of which Shanghai Stock Connect bought 6.792 billion yuan and Shenzhen Stock Connect bought 3.534 billion yuan.

Today is the third Friday in March, which is the delivery date of monthly stock index futures.

MorningThe central bank issued a notice saying that the central bank carried out a 7-day reverse repurchase operation of 13 billion yuan, and the winning bid rate was 1.8%.At the same time, a one-year medium-term loan facility (MLF) operation of 387 billion yuan was launched, and the winning bid rate was 2.5%, which was the same as before.

Wind data shows that 10 billion yuan of reverse repurchase has expired today, and 481 billion yuan of MLF has expired.

existDelivery day effectoverlayThe funds are slightly tight.Under the influence of the Shanghai Stock Exchange 50, Shanghai and Shenzhen 300, CSI 500, CSI 1000 and other major indexes have been slightly adjusted in early trading; 40 minutes before the opening in the afternoon, the decline narrowed slightly, but it continued to fluctuate.

The change node appeared at 13:42, when a sudden wave of continuous buying pulled the index up significantly.

Since then, the market sentiment has gradually warmed up. Since this wave of rebound, the Shanghai Composite Index hasFriday’s Invincible Golden BodyIt’s also maintained,The Shanghai Composite Index has even been 5 consecutive days a week.Yes.

So who was at the bottom?

According to observation,First of all, there is a high probability that the "national team" will participate.Because SSE 50, CSI 300, CSI 500 and other broad-based ETFs have almost simultaneously increased their volume in the steepest pull-up section of the index.

Secondly, it is the accelerated bargain-hunting of northbound funds.

It is worth noting that in addition to the above-mentioned "national team", the funds involved in the explosion today alsoThere is a foreign giant.The figure, that is the world’s second largest index company.FTSE Russell（FTSE Russell）。

The company had previously announced that it would transfer 76 A shares to the index, the index.Changing positions happens to be today.(March 15th).

According to the market value at the end of February this year, after this round of adjustment, A shares will increase from about 5.71% to about 6.18% in the FTSE Russell Emerging Markets Index, and from about 0.55% to about 0.61% in the FTSE Global Index.

The author noticed that among these 76 newly transferred stocks, many stocks are available today.obviousTime-sharing transaction

for exampleCapital securities、Jianyuan trustIn a certain minute, a huge amount of buying suddenly appeared.

There are also imagesHigh-tech developmentsuchIn the minutes before the close, the stock price continued to increase in volume.

And,Late bidding stageThese stocks and even the whole market have seen huge purchases.

To be sure, this adjustment willBring incremental passive allocation of funds for A shares.It is a good thing.Some media reports pointed out that since the beginning of this year, foreign investment has continued to increase.Even in the crash in early February, foreign capital was not the main force to kill the crash.

In short, today’s market bottomed out and turned red, initially ending the continuous adjustment for many days this week, and planting optimistic expectations for next week’s market.

For the market outlook, some people pointed out that,The market has entered a critical stage..

First of all, the A-share market has rebounded a lot since 2635, and the yields of many institutions are also very impressive. In the future, there are only many variables in the whole environment, so at this stage, it is normal to have a cash mood. From the perspective of the overall market structure, artificial intelligence, new energy, consumption and nonferrous metals have also had a round of gains.This stage requires chip precipitation..

Secondly,A shares are entering a performance-intensive disclosure period.. On Wednesday, Industrial Fulian plunged in late trading because the expected performance on that day may not be as good as expected. However, the diving of the stock has greatly affected the market sentiment. Tonight, Contemporary Amperex Technology Co., Limited’s annual report will make a big debut. Although the performance forecast is good, the stock price is quite depressed this morning. In other words, if there is an expected rise, it will not move, and if it is less than expected, it will plummet. At such times, funds will be "awe-stricken".

Third,A number of policies are waiting to be introduced.. This morning, it suddenly came out that the policy details of the implementation methods and standards of the automobile trade-in action plan are being formulated. If it goes well, it is expected to be introduced in the second quarter. Subsequently, auto stocks changed. Beiqi Blue Valley approached the daily limit, and jiangling motors, Yaxing Bus, Jinlong Automobile, Jianghuai Automobile, Haima Automobile and China Heavy Duty Truck followed suit. There are many similar policies, such as the market value assessment plan of state-owned enterprises and central enterprises.

Fourth,Peripheral variables are increasing.. According to the Japanese news agency on March 14th, the Bank of Japan is expected to end the negative interest rate policy at its meeting in March, and make a final decision after the results of the spring wage negotiations are announced on Friday. The media reported that the Bank of Japan will end the negative interest rate policy at the interest rate meeting to be held next week, and pointed out that it will make a final decision after studying the preliminary findings of this year’s Spring Fight (spring salary negotiation between Japanese enterprises and trade unions, also known as "Spring Fight" by the market) on the 27th. At that time, it is not known how much impact it will bring to the global market.

Finally, let’s look at the plate.

Concept of automobile disassemblyIt rose more than 9%, ranking first in the A-share concept sector, setting off a wave of daily limit.

In the news, on March 13th, the State Council issued the Action Plan for Promoting Large-scale Equipment Renewal and Trade-in of Consumer Goods, which opened a new round of trade-in of consumer goods.The "Proposal" proposes that by 2027, the recycling volume of scrapped cars will be about doubled compared with 2023, the trading volume of used cars will increase by 45% compared with 2023, the recycling volume of used household appliances will increase by 30% compared with 2023, and the proportion of recycled materials in resource supply will be further improved.

The program also stimulatedEnvironmental protection plateToday is strong.

On the other hand,Cultivate diamondsPlate sumanthropomorphic robotThe plate is also more active when the market as a whole is weak, with the highest increase.

Regarding the former, since March, the market has been constantly spreading.Cultivate diamonds and raise pricesAccording to the news, some leading enterprises have reported that the current production and sales are full, and there is basically no inventory. The overseas demand continues to improve and the domestic recovery is also very good.

Wanlian Securities said that in the short term, the year-on-year growth rate of India’s cultivated diamond rough imports slowed down in January, and the export of cultivated diamond rough diamonds turned from negative to positive year-on-year, indicating that the demand for cultivated diamonds rebounded in January. In addition, the import of natural rough diamonds rose sharply year-on-year, and the decline of loose diamonds was narrowed year-on-year. However, the price of finished diamonds fell slightly, still fluctuating at a low level. In the medium and long term, with the gradual recovery of the macro-economy and the further popularization of the consumption concept of "please yourself", the downstream consumption demand of diamonds is expected to gradually recover. However, cultivated diamonds have the same composition and structure as natural diamonds, and have a greater advantage than natural diamonds in price. Combined with the education of downstream consumers by media and brands in recent years, the penetration rate of cultivated diamonds is expected to be further improved in the future.

As for humanoid robots,near futureThere are also new trends in the industry.

At the 2024 China Household Appliances and Consumer Electronics Expo, Haier Robot and Leju Robot jointly exhibited the first humanoid robot for family scenes in China — — Kuavo。 According to reports, Kuavo, as the first open source humanoid robot in HarmonyOS that can jump and adapt to multi-terrain walking in China, not only showed its control performance such as jumping and walking quickly, but also showed the hand operation results of washing, watering flowers, arranging flowers and drying clothes recently.

Open source securities said that there is no doubt about the prospect of humanoid robots in the case of giants entering the game. AI and software accelerate iteration, and hardware supply becomes the key to mass production of robots. Compared with the cognitive decision-making system whose performance has been greatly improved after AI empowerment, it is more difficult to acquire hardware with high reliability, high performance, light weight and low cost. No matter how the competition pattern of humanoid robot manufacturers is interpreted, mass production needs to be realized by reliable and low-cost hardware. The domestic supply chain with strong following, manufacturing and cost reduction capabilities is expected to usher in good results.
