The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 189, Liu Xiaoli (More updates, please subscribe)

In the handheld game console project department office, Wang Duoyu played the game for nearly ten minutes before he began to inquire about the details of this product.

Just now, Yin Wenjie and Zhang Jikang, the two heads of the software and hardware departments, have briefly introduced some basic parameters of this game console, such as battery life and size, but they did not mention the most critical game content, whether there will be screen problems, whether the game console will heat up, etc.

A high-quality product must naturally be able to withstand multiple tests and inspections.

"If a game console runs continuously for 30 hours, or even longer, will there be any accidents? If the product leaves the laboratory and goes through the factory production stage, what is the pass rate?"

"Is the battery stable? If it is continuously connected to an AC power source, will there be other safety issues? Have you tested these?"

"Also, I don't know if it's a problem with the sound processor or the speakers themselves. When I was playing games, the sound was a little laggy and delayed. I also don't know if the game cartridge is working."

Wang Duoyu asked a series of questions, which made Yin Wenjie and others hurriedly write them down.

The handheld game console project is a very important product. For Huashun Company, it is the new product that will be promoted this year or next year.

If this game console is successful, it will definitely earn more foreign exchange.

For Harbin Institute of Technology, this is not only an honor, but also the lifeline and the hope for rise.

"Professor Wang, don't worry, we will definitely complete these tests as soon as possible and try not to delay the release of next year's game console."

After finishing the recording, Yin Wenjie patted his chest and made a promise.

In response, Wang Duoyu just nodded and said, "I hope so."

A project lasted for nearly a year and a half. To be honest, it was a long time and it should have borne fruit.

If he has to wait another year or two, Wang Duoyu might really lose his patience.

The "China Cube" cartridge was already on the market in March this year, but the handheld game console still needs to wait for another half a year. Even so, it is not known whether it will be available at the end of this year or the beginning of next year.

After leaving the handheld game console project department, Wang Duoyu went to the lithography machine project again.

Among so many projects, the lithography machine is the most difficult and also the one that requires the most investment.

Other projects have gradually seen the light of day, but the progress of the lithography machine project is only around 70%, and it is not known whether a product can be produced before the end of this year?

However, the lithography machine project is starting from scratch after all, so it is normal to be slow.

When Wang Duoyu finished his work and returned to the office, there was actually someone waiting at the door.

Several foreigners were waiting at the door very stubbornly. When they saw Wang Duoyu, they rushed over with great surprise and couldn't wait to ask their questions.

"I understand your question. I will definitely answer it on the day of the lecture, but right now, I need to be busy."

Wang Duoyu smiled and refused.

He would not explain it repeatedly, and the new mathematical tools would take at least half an hour to explain. Most importantly, these people would probably need more than ten or twenty class hours to understand it.

So it was impossible for Wang Duoyu to explain these things to them individually.

After saying this, he also reminded the two security staff members standing guard at the door not to waste time waiting at the door in vain for such things in the future.

As soon as he finished speaking, the doctors couldn't help but say:
"Professor Wang, we respect you very much. We have come all the way to Harbin Institute of Technology. Why wouldn't you explain it to us?"

Isn’t this just moral kidnapping?

Wang Duoyu keeps smiling:
"I'm not looking down on you. I've published this paper five months ago, and you still haven't understood this mathematical tool. I can only say that your mathematical talent is indeed a little lacking."

"Trust me, you won't understand the lecture in half a month. If you really want to understand this paper and learn these mathematical tools, you can sign up for my course starting in mid-October."

Wang Duoyu would naturally not let the foreigners who came to him leave easily.

One thing that is very obvious is that after the lecture, most people will leave Ice City. This is inevitable.

But if Wang Duoyu started two courses at this time, one would be specifically for the ABC conjecture, and the other would be for the previous Fermat conjecture.

Then there will definitely be many people willing to stay.

Especially regarding Fermat's conjecture, Wang Duoyu guessed that some people would come to study with a purpose, and some were even students directly funded by those code-breaking institutions.

Because the biggest application of Fermat's conjecture is about keys, encryption algorithms, etc., this is a huge matter for code-breaking institutions such as special agencies.

Although many people are very reluctant, they need to understand one thing, that is, Fermat's conjecture has been proved by Wang Duoyu.

If they want to find out, they can only send people to Harbin Institute of Technology to study.

"Thank you, Professor Wang. We understand."

Upon hearing this, the foreigners were not angry, but left happily.

why?
Because what Wang Duoyu said just now was already polite enough. If it were any other professor, he would have probably cursed.

Chinese people may not be very clear about this, but foreigners know one thing best: the world's mathematical center is undergoing tremendous changes.

As Wang Duoyu successively proved world-class top problems such as the Poincare conjecture, Fermat conjecture, and ABC conjecture, the global center of mathematics seemed to have changed.

Haven’t you seen that in the past few years, many foreign mathematicians have been rushing to China’s Ice City?

Although from the current perspective, neither Gerd Faltings nor Andrew Wiles have produced any impressive scientific research results, there is no doubt that Wang Duoyu, this cheater, has influenced many people.

Among them, Yang Nianzhen, Yorks and other six people who were called lucky ones by foreign media, after they became Wang Duoyu's students, the topics they studied were thoroughly analyzed by foreign media.

Hundreds of media outlets used more than three pages of articles to analyze the situations and research topics of their six students.

Some people even started private auctions to bet on which student would be the first to complete the research projects and produce top-notch results.

The project of this doctoral student, Bocherz, has been delayed for more than ten years. Many people do not think it can be solved within ten years because this problem is the Monster Moonlight Conjecture.

However, if he could prove the problem within fifteen years, Borchers would have a chance of winning the Fields Medal.

Fifteen years would be impossible if Bocherz only relied on himself.

But what about adding Wang Duoyu?
You know, Bochers is only 22 years old this year, and he will only be 37 years old in 15 years. He will definitely win the Fields Medal before he turns 40.

In this context, and because of the lecture, many foreigners naturally came to Harbin Institute of Technology.

Life is nothing but fame and fortune, and foreigners are more realistic.

Otherwise, the American soldier in his previous life would not have run to the streets of the peninsula and randomly picked an Oppa to beat him up just because of a joke made by a Chinese netizen.

After watching the foreigners leave happily, Wang Duoyu shook his head and laughed, then turned around and went back to the office.

After get off work in the afternoon, when he returned home, his sister Lao Shiyi suddenly said:

"Brother Jiu, Baoyin and Jianchao called us and they want to come visit us tomorrow."

"Come on, why are you asking me?"

Wang Duoyu asked curiously. His two younger sisters were quite righteous and usually made decisions on many things on their own. As an older brother, he didn't need to worry too much.

Even some time ago, regarding the education of his son Wang Junhong, his two sisters made many suggestions. Although Wang Duoyu did not adopt any of them, they did have a lot of ideas.

Wang Meili saw that her sister was still very shy, so she rushed to say:

"Brother Jiu, Baoyin and Jianchao got into a fight with someone and are broke. They want to borrow some from us."

After hearing what Old Twelve said, Wang Duoyu suddenly understood.

When they were celebrating the Spring Festival in their hometown at the beginning of the year, Zheng Baoyin and Wang Jianchao mentioned to Wang Duoyu that they wanted to work as workers in Diao Pai Company, but were rejected by the latter.

At that time, Wang Duoyu suggested that they set up stalls and go out to try their luck. Being a worker had no future, and they did not have the academic qualifications.

So they really came to Bingcheng to make a living. Once, Wang Duoyu saw them both at Bingcheng Railway Station.

From March to September now, I have been "wandering" outside for more than half a year. Unexpectedly, I got into trouble this time and actually got into a fight with someone.

"You should have money, so just lend it to me if you want. I don't think their injuries from the fight are serious, right?"

"It's not serious, but we don't want to lend them money."

The two sisters' expressions changed slightly when they heard this.

Although Zheng Baoyin and Wang Jianchao are both their nephews and nieces, they don't want to borrow money from them.

Because it is not easy for them to make money, and Zheng Baoyin and the other two are not very stable. They can only brag but are not reliable at all when it comes to doing things.

If we really lend them money, it will definitely be a waste of money. Otherwise, how could the money they brought in at the beginning of the year be gone?
If they still have money, why would they need to borrow money from them?
Wang Duoyu was immediately amused and said, "Then you can ask them to come to me. I will find time to talk to them tomorrow."

Although Wang Duoyu really wants to be an angel investor, it also depends on whether Zheng Baoyin and Wang Jianchao are worthy of investment.

It cannot be said that just because they are relatives of the Wang family, Wang Duoyu trusts them unconditionally. It is not like that.

The two sisters were immediately overjoyed. As long as their ninth brother was willing to take care of this matter, they wouldn't have to worry about it.

The next day, in the evening, Zheng Baoyin and Wang Jianchao came to Wang Duoyu's house again.

They looked at the delicious fish and meat on the table, and their eyes suddenly flashed with green wolf light.

"Eat, and then we'll chat after you're full," Wang Duoyu said happily.

On weekdays, he eats more vegetarian dishes. He eats meat at every meal, but not much at each meal.

The reason why there are so many fish, shrimp, chicken, pork, etc. today is all because of Zheng Baoyin and Wang Jianchao.

"Uncle Jiu, are those liquors? Can I have a glass?" Wang Jianchao saw the Wuliangye liquor on the shelf in the living room and asked with a flattering face.

They hadn't had a drop of alcohol for more than half a year since they left their hometown in early March, so they were really craving for this.

"Sure, but after you finish drinking, forget about borrowing money from me."

The smiles of Zheng Baoyin and Wang Jianchao froze for a moment, and the next moment they asked in unison in ecstasy:
"Uncle Jiu (Ninth Uncle), are you willing to lend us some money?"

They were almost in tears. Only they themselves knew what they had been through in the past six months.

Especially the time when I set up a stall at the train station, it was such a torture.

Zheng Baoyin and Wang Jianchao are just authentic farmers, very honest people.

Despite taking every precaution, they still had all their belongings taken away after only half a month of setting up a stall at the train station.

Then they began their long journey of revenge, wandering back and forth between the righteous path and the gray area, almost falling into the abyss and embarking on the dark path.

Those who have not experienced this kind of suffering have no idea what it is like.

At the same time, they also understood that money is the most important thing.

They had heard the saying "Money makes the world go round" before, but they had never imagined that it would be so painful when it happened to them over and over again.

"Haha, when did I ever say I'd lend you money? Let's eat first, then we'll talk."

Wang Duoyu smiled and said to everyone.

"Nerd" Zheng Baodong was also at the dinner table, but he was really silent. Apart from greeting his brother and Wang Jianchao at the beginning, and calling them Wang Duoyu at most, he remained silent at other times.

Zheng Baoyin and the other man looked at each other and knew that now was not the time to chat, so they picked up their bowls and chopsticks and started to eat voraciously.

After a hearty meal, Zheng Baoyin couldn't wait to ask about borrowing money, but was interrupted by Wang Duoyu.

"First, tell me what you've been doing in the past six months. What have you done? Don't lie or exaggerate. Just tell me the truth."

Wang Duoyu wanted to understand their situation clearly first before giving targeted advice.

He told Zheng Baoyin and others about it when he was in his hometown after the Spring Festival, but they were still young at that time and didn't listen at all.

After all, in their opinion, Wang Duoyu is a scholar, and in terms of social experience, he may not be inferior to them.

There is no need to ask now, they have already regretted it.

It’s a pity that there is no such thing as medicine for regret in this world.

After Zheng Baoyin and the others finished speaking, Wang Duoyu pondered for a moment and said:
"You guys deserve it!"

"Forget it half a year ago. There's no point in saying this now. Now, I'm going to give you some advice. Can you listen to it?"

The two nodded like rattles, without a moment's hesitation.

The next suggestion Wang Duoyu gave them was to go to the south to purchase goods, sell those nice-looking electronic watches and other products, and bring them back to Beijing, Ice City and other places for sale.

But one thing to note is that these goods cannot be stolen or caught by anyone.

Because even though it is 1981 now, the social atmosphere in many places seems to be simple and honest, but in fact it is extremely fierce.

Especially public places like trains, which are definitely the favorite places for thieves and other scumbags.

So in addition to being extremely careful when transporting goods, you also need to be careful of those in official uniforms.

It’s hard to say whether it’s a human or a ghost!
When you are out, you need to speak the truth to people and lies to ghosts.

If it really doesn't work, then we can only rely on money to pave the way.

Zheng Baoyin and the other man nodded repeatedly, and Wang Duoyu continued:

"I'll only give you 100 yuan as a starting point. If you can make 5,000 yuan before the Spring Festival, then after the Spring Festival next year, I'll arrange a good big project for you."

As soon as these words were spoken, the two of them immediately counted on their fingers, and then felt despair.

A hundred-yuan capital will take more than three months, less than four months, from mid-to-late September to the New Year's Eve on January 24th next year.

How is it possible to make 5,000 yuan in such a short time?
Even the sisters Wang Meili and Wang Meihe widened their eyes and exclaimed that it was impossible!
However, Wang Duoyu looked at Zheng Baodong with a smile and asked:

"Xiaodong, tell me what you think."

The latter suddenly became nervous because he knew that his ninth uncle was testing him.

If it was just a simple math problem, Zheng Baodong thought he would have no problem, but this kind of real business problem was extremely difficult.

Seeing that he hesitated for a long time and didn't say anything, Wang Duoyu was not disappointed, but chuckled and said:
"Baoyin, Jianchao, you two are so ambitious and have been struggling outside for more than half a year. Don't you have any ideas at all? You know how to borrow money from me, so why not ask others for money?"

Zheng Baoyin's face lit up with joy when he heard this, and he suddenly realized:

"Uncle, do you mean that when we have a little capital, we can borrow money from others? And then we can grow bigger and bigger?"

Wang Duoyu nodded slightly and continued:

"Borrowing money is just the simplest method. Go ahead and do it. Once you've completed two sales tasks, come back to me."

"Remember, this is a profitable business. Don't disclose it to anyone easily, regardless of whether they are trustworthy or not. You must not tell anyone. I believe you should understand what I mean, right?"

Both of them had experienced the beatings of society, so they immediately understood this truth.

If they tell trustworthy people, such as their brothers and sisters, those relatives will probably go into the business themselves, or they may ask them to guide them.

Even if the result is good, Zheng Baoyin and others may not be happy. If the result is bad, for example, those relatives' electronic watches were taken away on the way, or their money was stolen, etc.

Then at that time, Zheng Baoyin and others will definitely bear part of the losses, or come and accuse them of being dishonest.

As for informing those so-called "good brothers and friends" about this matter, that goes without saying. Therefore, it is best for them to do their best.

"Uncle Jiu (Ninth Uncle), your words reassure us. We will definitely listen to you. If you tell us to go east, we will definitely not go west. If you tell us to catch chickens, we will definitely not chase dogs."

"In a word, we are the gun in your hand, shooting wherever you point it."

Zheng Baoyin and Wang Jianchao nodded repeatedly, indicating that they would definitely listen to Wang Duoyu and would not make any concessions.

In response to this, Wang Duoyu smiled without comment.

Just at this moment, the phone at home rang. Wang Meili hurried to answer it. She thought it was Zhu Ling calling.

Since the beginning of August, when Zhu Ling cruelly left her child to Wang Duoyu, she called him every day for the first half month, and then only every two or three days.

It's September now, and she only makes a phone call about once every four or five days. According to Zhu Ling herself, she has been very busy recently, trying to lose weight on the one hand and learning acting on the other.

Because she has received an invitation from the director, she will probably join the crew in October.

Wang Duoyu didn't want to say anything, and there was nothing much to say. The child's mother wanted to pursue her dreams, and there was nothing much to say.

He couldn't stop it, so he just turned a blind eye.

"Ah? You are not my sister-in-law? Then who are you?" Wang Meili's words immediately made everyone in the living room look at her.

Liu Xiaoli, who was on the other end of the phone, couldn't help feeling sour when she first heard a woman's voice. She thought the woman who answered the phone was Zhu Ling.

As a result, Wang Meili introduced herself and asked Liu Xiaoli if she was her sister-in-law, which made Liu Xiaoli very happy.

However, before Liu Xiaoli could deny it, Wang Meili recognized it again. After all, what the former said was a bit irrelevant, which made Wang Meili realize that this was definitely not Zhu Ling's sister-in-law.

"Okay, give me the phone." Wang Duoyu had already guessed something, so he hurried over to answer the phone.

After a few nods, Wang Duoyu rejected Liu Xiaoli's invitation and hung up the phone.

Liu Xiaoli wanted to ask Wang Duoyu to meet at the old place, but it was so late, it was definitely not suitable, and the meeting should be in daytime.

But he is not free during the day tomorrow, so let's talk about it later.

In fact, Wang Duoyu wanted to ask Liu Xiaoli how she got his home phone number, but Zheng Baoyin and the others were there, so he gave up the idea.

The next day, Zheng Baoyin and Wang Jianchao took a hundred yuan and started their life as street vendors.

They found a fellow villager named San Ye, whom they had known for a long time, near the train station and borrowed 300 yuan from him, with the promise of returning 400 yuan within a month.

It's definitely usury.

The third master was originally from Qingshan Township, Shuanghe County. He naturally knew the Wang family in Dahonggou Village, so he dared to lend money at such high interest rates.

After borrowing 300 yuan, Zheng Baoyin and his companion immediately bought train tickets to Baiyun City in the south and arrived in Baiyun City the next day.

A few days later, they arrived at Baiyun City. Without taking a rest, they immediately began to inquire about the news.

After confirming the situation, I spent two days purchasing the goods and then bought a train ticket north.

This time when they came back, they did not go directly to Ice City, but came to the capital.

Unlike their previous miserable experience of setting up a stall at the Ice City Railway Station, this time they had experience and quickly sold all the goods in their hands.

"Achao, is this true? In just over a week, we've already made 537 yuan? Isn't that too much of a profit?"

The total amount of money they brought with them was a little over three hundred, because train tickets were quite expensive.

Ah!
Suddenly, Zheng Baoyin couldn't help but scream because Wang Jianchao twisted his arm and he grimaced in pain.

Suddenly, angry curses came from the next room. After all, it was night time and it would disturb people's sleep.

"Fuck, Ah Chao, you're too cruel! You're using so much force that your skin is all red and swollen."

Zheng Baoyin was a little angry and slapped Wang Jianchao, but he soon came to his senses because everything he saw was real.

It's incredible that you can make so much money by buying those imported goods from Baiyun City in the south and reselling them.

After counting the money again, Zheng Baoyin discussed with Wang Jianchao and decided to go to Baiyun City again and return quickly. They should be able to make more money.

In this way, they don’t even need to talk to Wang Duoyu about this, and the two of them can quickly earn 5,000 yuan before the Spring Festival.

The two of them quickly left the capital and headed for Baiyun City in the south. When they arrived at the Beijing train station and were about to board the train, they saw many foreigners and were immediately very surprised.

"Are all these foreigners going to Ice City? I remember Xiaodong saying that their school is going to hold a meeting in October and listen to Uncle Jiu's lecture or something."

Hearing Wang Jianchao's words, Zheng Baoyin nodded, feeling very proud.

Unfortunately, neither of them knew what this meant and could only guess.

On the other side, the campus of Harbin Institute of Technology has become a little more lively.

Banners had already been hung at the main gate of the school, and there were even a lot of flowers placed at the gate.

These flowers are new varieties of flowers cultivated with the help of the nearby Academy of Agricultural Sciences and have been reserved by Harbin Institute of Technology.

This is the first time in the history of Harbin Institute of Technology that such a large-scale international academic exchange meeting has been held. Although it is not National Day yet, more than 300 foreign mathematicians have arrived at Harbin Institute of Technology.

That’s not even counting the mathematics professors and graduate students in other domestic universities.

In short, this conference will be a grand event in the global mathematics community, and its popularity will be almost the same as the one held at Princeton University last year.

The teaching building of the Department of Mathematics at Harbin Institute of Technology seemed to be gradually occupied by foreigners.

If there weren't a lot of students with Chinese faces, many people would have thought this was a foreign university when they walked into the Department of Mathematics building.

There are many people coming and going, but it seems that all this has nothing to do with Wang Duoyu. He still does what he should do.

There is a notice posted on the bulletin board on the first floor of the teaching building a week ago, and it has not been removed until now.

The announcement states that Professor Wang Duoyu will open registration for courses on the ABC conjecture and Fermat's conjecture after the lecture. Students who want to participate, please register in advance and be prepared.

Experienced sophomores, juniors, and seniors must know that if you want to take Wang Duoyu’s courses, you need to take an exam, and only after passing the exam can you attend the class.

If it were other professors in other departments, students’ attitude would be that if they wanted to listen, they could listen, and if they didn’t want to listen, that was fine too.

Do I have to take an exam and pass the assessment before I can attend classes?

It's crazy!

This is a thoughtful arrangement, not something cruel that drives students out. After all, Confucius said that there is no distinction between people in education.

This announcement did not cause much sensation among students in their sophomore year and above, but it caused a huge wave among the freshman year.

However, while the freshmen were busy registering and looking forward to taking the exam, many people abroad had already received this news.

When Theodore Wagner of the U.S. Security Agency's Special Office learned that Wang Duoyu was actually going to teach, he stood up in surprise:
"Are you telling the truth?"

The agent nodded, indicating that it was absolutely true!
It has been posted on the bulletin board of the teaching building of the Department of Mathematics at Harbin Institute of Technology, and all the teachers and students in the department are discussing this matter. How could it be fake?

"Good good!"

After receiving confirmation again, Theodor Wagner was overjoyed.

This is a godsend!

The papers proving Fermat's conjecture have been thoroughly studied by them. These two papers are naturally not a big problem for top mathematicians, but for special firms, it is not such a simple matter.

Even Brutus Freke, the chief expert of the special agency, took a very long time to decipher the first paper. The reason why it took so long was that he was no longer an expert in pure theoretical mathematics. In addition, he was old and also needed to study theories related to encryption algorithms, which made it even more time-consuming and laborious.

Therefore, if it were someone else, it would definitely be more difficult.

It would undoubtedly be difficult for Brutus Freke to teach others.

But now Wang Duoyu actually took the initiative to suggest that I could sign up for such a course, which was really great.

After confirming the news, Theodor Wagner immediately mobilized some personnel and gave them $200,000 to go to Harbin Institute of Technology, with only one requirement: they must learn the two papers on Fermat's conjecture.

As for the mission of kidnapping or assassinating Wang Duoyu, forget it.

On the campus of Harbin Institute of Technology, they have no chance at all.

Even outside of school, they have no chance now.

What's more, since July, when Wang Duoyu returned to Harbin Institute of Technology from Mohe, he has become a stay-at-home and rarely leaves the campus.

When Theodor Wagner sent twelve 'interns' to Ice City, other countries such as Great Britain, the Polar Bear Empire, France, and Japan also sent their own 'students' there.

Today in 1981, cryptography is still a very important means, especially in the field of information transmission.

The Internet is just emerging now, and information transmission relies more on radio and telephone because it is faster, more convenient and more efficient.

Not to mention phone calls, eavesdropping is inevitable, and encryption methods, signal shielding, etc. are also necessary.

The most critical aspect of radio information transmission is how to encrypt it.

All countries knew that there was a big secret hidden in the two papers in which Wang Duoyu proved Fermat's conjecture. Although the papers were public, there was nothing they could do. Wang Duoyu's teaching ability was obvious to all, so everyone worked hard and sent people to Harbin Institute of Technology.

In order to get more people to come to Harbin Institute of Technology to attend this lecture, Wang Duoyu really put a lot of thought into it.

He has already made his thesis public, so is he still afraid of these people coming to attend his lectures?

Fermat's Last Theorem is completely different from the strong solution of the Navier-Stokes equations. Although the encryption algorithm of the former is also very powerful, it is not completely without countermeasures, and other encryption algorithms can also surpass Fermat's Last Theorem.

The proof paper of the ABC conjecture also involves elliptic curves, modular forms, L functions, etc. Even the Magic Group Moonlight Conjecture has a certain connection, not to mention other more complex encryption methods.

So, if Wang Duoyu wants to encrypt, foreigners will not be able to continue playing.

In the blink of an eye, it is October 1st, which is National Day.

There was no military parade that year, so Wang Duoyu did not go to Beijing, but he still took his son to attend the school's flag-raising ceremony.

It was a very rare experience. Harbin Institute of Technology is a university under the Seventh Ministry of Machine Building, but it is also one of the Seven Sons of National Defense.

Therefore, flag-raising ceremonies are still necessary on major holidays such as National Day.

Especially since there are so many freshmen this year, more than 6,000, they should be allowed to participate.

After attending the flag-raising ceremony, Wang Duoyu prepared to ask his sister to take his son home and then go to the office himself. As a result, at this time, he ran into Liu Xiaoli.

"Why did you get in?"

It is extremely difficult for outsiders to enter Harbin Institute of Technology now.

Everyone entering Harbin Institute of Technology must have a student ID or teacher ID, and everyone must carry this ID.

Each person’s ID card has a photo, name, department, etc., which is very clear and easy to see at a glance.

Even those members of the visiting scholar exchange group who were brought in by bus had temporary documents with photos on them.

Liu Xiaoli heard this and took out her own sign with a smile:

"Well, I am now a member of Harbin Institute of Technology"

What she took out was a teacher's ID card, but when did Harbin Institute of Technology recruit dancers as teachers?
Wang Duoyu took a closer look and remembered one thing. That is, starting from September this year, the school seemed to have some performances, and temporarily recruited some teachers from outside to guide students in performing arts performances.

As the great man said, we should develop morally, intellectually, physically, aesthetically and labor-wise in an all-round way.

But in Wang Duoyu's opinion, for a science and engineering college like Harbin Institute of Technology to let students dance is pure nonsense.

"What do you want from me?"

Looking back at his two sisters who had already left with their son, Wang Duoyu looked at Liu Xiaoli again, then walked towards the mathematics department building.

Liu Xiaoli looked at the people around him, with a complicated look in her eyes, and said with a forced smile:
"I'm here to tell you about your previous readers' letters. I've opened and read them all for you. There are a total of..."

Before she could finish, Wang Duoyu interrupted:
"You don't need to tell me this, just keep it to yourself. Take one-fifth of the money and save the rest."

Although there is a high probability that he will not be able to use this money, in fact, neither he nor Liu Xiaoli has any need to use this money.

After all, daily living expenses and the like can be fully covered by the salaries of both Wang Duoyu and Liu Xiaoli, and there is even some left over.

As for using this money to buy a car for Liu Xiaoli, haha, we are not able to support private car purchases at this stage, so it is too early to talk about this.

In about three years, individuals will be able to purchase cars at will.

By that time, Wang Duoyu himself will definitely buy a car, and it would be best to buy an imported car.

It’s not that Wang Duoyu is unpatriotic, but the current domestic industrial strength is indeed too poor.

When you buy a car from abroad, you can ask someone to help you modify it, such as adding leather seats.

"Nothing else, right? I'll get back to work. Please do as you please."

"Wait a moment!"

Liu Xiaoli plucked up her courage and took a step forward, but she didn't see the two men two meters away, and her expression became nervous.

Although Liu Xiaoli was harmless and the two guards had guessed her relationship with Wang Duoyu, they were still very nervous.

Anyone who approaches Wang Duoyu is extremely cautious.

She didn't see it, but Wang Duoyu noticed it.

"I know you'll be giving a lecture in the auditorium on the 5th. Can I attend your lecture then?"

Wang Duoyu looked at her strangely when he heard this:
"Do you understand why you came to my lecture? I'm not looking down on you. Even among the freshmen in our mathematics department, the number of people who can understand the lecture can be counted on one hand. What do you mean..."

"Don't come. You won't understand even if you come, and it's a waste of your ticket!"

Liu Xiaoli immediately glared at him angrily, "You said that, and you still say you didn't look down on me?"

It's just like looking at people through the crack of the door!
Wang Duoyu did not comment on this.

Seeing that he didn't say anything, Liu Xiaoli couldn't help but feel discouraged.

She is not an idiot, so how could she not know how difficult Wang Duoyu's math paper is?

Not to mention that she was an outsider, even many university mathematics professors might not be able to understand it. She had read the news reports about the ABC conjecture that Wang Duoyu had proved before. It was said that there were only about ten people in the world who could understand this paper.
