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

Chapter 148, Auditor Qualification and Lu Jiaxi (Happy New Year!)

On July 10, 1979, on the campus of Harbin Institute of Technology, many students came to the auditorium.

Because many people came here because of its reputation, more students from other departments who stayed on campus came.

The class originally scheduled for 10 o'clock has been postponed by ten minutes.

Wang Duoyu didn't expect that so many people would want to come and listen to his lectures. To be honest, he felt very surprised and speechless.

On the podium, he looked at the huge crowd below and couldn't help but say:
"There are so many people attending my lecture today. This isn't something to be happy about. Although you've come with such enthusiasm, I should be happy. But actually, my main topic today is the Poincare conjecture in four-dimensional space, which is a problem in mathematics."

"Not to mention students from other departments, even in our Department of Computational Mathematics, over 70% of us probably wouldn't understand."

"So, in today's first class, I won't waste everyone's time. If anyone doesn't understand, please speak quietly. It's best not to make any noise and just leave quietly. Don't disturb the class discipline."

"I give lectures for the first 45 minutes, and the last 15 minutes are for questions."

"Okay, enough of the nonsense, let's get started with the lecture."

He did not repeat what he had said before, but went straight to the first paragraph of the first page of the paper.

Most of the students in the Department of Computational Mathematics here have certainly read his paper, so there is no need to elaborate on it.

Most of the people under the podium listened to the lecture seriously, only a few thought that Wang Duoyu was too pretentious.

Many students who were not from the Department of Computational Mathematics were quite arrogant at first, but after Wang Duoyu spoke for less than ten minutes, they were completely confused:

What is Professor Wang talking about?
Where am I?

What’s the difference between this and the Book of Heaven?
However, even though they didn't understand, they stayed and didn't rush to leave.

Not long after, some students from the Department of Computational Mathematics also became confused. They also didn't understand.

It's normal. Some people really don't understand because it touches upon their blind spots in knowledge.

For example, some students who are still in the basic class are trying very hard to keep up, but their talents are limited. If they can't do it, they just can't do it, and they can't force themselves to do it.

Lou Jianguo also began to find it a bit difficult to listen, but he still listened carefully.

Lou Jianguo had not attended the previous lecture at Tsinghua University or the academic conference at Peking University. It was a good thing that he did not go, otherwise it would have been a waste of time.

This time, Wang Duoyu spoke in great detail, spending forty-five minutes explaining the first page of the paper.

Then it's time for questions.

When it was time to ask questions, some students from other departments began to leave because they really didn't understand and there was no point in staying.

Although they were asking questions, in fact, the questions everyone asked were very simple, which made Wang Duoyu want to give up.

Because the Poincare conjecture is really not suitable for everyone, simply because it is really too difficult.

So, after the fifteen-minute question period, Wang Duoyu reminded everyone again:

"For those students who don't understand, I advise you to leave first. The paper on the Poincare conjecture in four-dimensional space is still too difficult for you."

"Well, we won't have a lecture tomorrow morning. I'll give you a test. As long as you pass it, you can come to my class. Otherwise, it would be a waste of everyone's time."

hiss!
In the auditorium, many people gasped, and some students looked at each other in surprise: This world is too crazy, you actually need certain qualifications to attend lectures?
Regardless of whether it is crazy or not, at least it can screen out some students, so Wang Duoyu is suitable to continue the lecture.

And even if people can come to his class, he believes that there will not be many people who can stick to it to the end and still understand it.

Teachers such as Wu Congxin, Liu Taoshun, Su Zhenghuai, Yang Xiuhua, and Shao Zongjian had different reactions when they heard this. In the opinion of Wu Congxin and Liu Taoshun, Wang Duoyu's move was a bit too hasty.

Confucius said, there is no distinction in teaching!

There is absolutely no need to set thresholds to eliminate students who are extremely passionate about mathematics, right?

What if there are students among them who have great mathematical talent but are late bloomers?
Isn’t Shing-Tung Yau a living example?
Before proving the Calabi conjecture, Shing-Tung Yau's mathematical talent was not particularly outstanding. He could only be considered a leader among all mathematics PhDs, but he was not exceptionally talented and far surpassed everyone else.

For Su Zhenghuai, Yang Xiuhua and others, it would naturally be better if more students could be eliminated.

why?
Students who have been to college know that when taking classes in a lecture hall, students tend to be more inattentive because there are too many people. Only professional courses are taught in the classroom.

There is of course a big difference between one-on-one training and one-to-many teaching.

Xue Xiaoling, Rong Guangxia and others were also very happy because they were confident that they could pass Wang Duoyu's test.

In particular, they also knew the basic topology textbooks mentioned by Wang Duoyu before. They had taught themselves topology-related knowledge and had read the first few pages of the paper on the Poincare conjecture in four-dimensional space. They should have no major problems passing the lecture assessment.

Students like Jian Xianglan and Zhu Hanting, who have already obtained the qualifications to study in the United States, are feeling the most complicated at this moment.

Foreign scholars all came to China to listen to Wang Duoyu's report. They clearly had such an opportunity, but at this critical time they went to study in the United States.

Is this like picking up sesame seeds and losing watermelons?
I guess it’s just barely true!
However, there are also many opportunities in the United States, and I hope to learn more there.

The next morning, Wang Duoyu did not bring the test paper. Instead, he wrote ten questions directly on the blackboard, then put down the chalk and let everyone do the questions on their own.

Zhu Hanting’s eyes suddenly widened: Is this too difficult?

Rong Guangxia, Xue Xiaoling, Yuan Jigang and other students also couldn't believe their eyes after seeing the questions.

They were all long questions, and there was not a single simple question like multiple choice or fill-in-the-blank question.

So, if you don’t know how to do it, then you don’t know how to do it. It’s impossible to take shortcuts!
"During the three-hour exam, you can look up the text in your textbooks, but you are not allowed to discuss or make any noise. You just need to maintain discipline in the exam room."

When people heard Wang Duoyu's words, they were not happy but terrified.

If it were a liberal arts subject, you would definitely be able to find the answer by flipping through a book, but this is mathematics, so flipping through a book is useless.

Open-book exams are completely useless for mathematics because there are no answers in the book.

Lou Jianguo and his classmates are all students majoring in mathematics. They have also read the books related to topology that Wang Duoyu told them about a few months ago.

Not to mention that they didn't bring all the books to the classroom, even if they did, it would be useless.

Many students from other departments were immediately amazed when they heard Wang Duoyu's words: "Is there such a good thing? It's actually an open-book exam, that's too good to be true! Only ten questions, and three hours to finish. If I can't get all of them right, I can at least get eight right, right?"
Soon, the students began to flip through the books.

But they made too much noise when flipping through the books, so Wang Duoyu scolded them directly.

After more than half an hour, they had finished flipping through all the books they brought, but they still couldn't find any symbols related to the ones on the blackboard.

Then a classmate couldn't help but raise his hand. Wang Duoyu was reading a book. Only after being reminded did he realize that a classmate had a question.

"whats the matter?"

Wang Duoyu came up to the other party and asked patiently.

Finally, the other party stood up and said:

"Professor Wang, how come none of the ten questions you gave are related to the textbook? Aren't you making things difficult for us?"

At this time, many classmates cast curious glances at him, and everyone felt the same way when they heard the classmate's question.

"The Poincaré conjecture is a problem in basic mathematical theory. As a non-mathematics student, you shouldn't be attending my class. I set the question so as not to waste your time."

After a pause, Wang Duoyu continued:

"I told you to look it up in the book, but I didn't say the answer is in the book. Look at the other students. They still have my paper, but don't they all look like you, scratching their heads and frowning?"

"Math is like this. If you don't know something, you don't know it. If you don't understand something, you don't understand it. I advise you to put math aside and learn your own major as soon as possible."

In an instant, the classmate's face turned red with embarrassment, then he stood up and ran away.

Shame on Dafa.

Inside the examination room, a chuckle suddenly rang out, and Wang Duoyu immediately shouted:
"Keep quiet and don't disturb other people taking the exam."

He felt very calm when being called Professor Wang. After all, he had heard of it countless times in his previous life.

Back at the podium, Wang Duoyu sat down and continued to invigilate, well, actually just read a book.

The whole thing about invigilation and no invigilation is totally a lie.

It's just an open-book exam, why does it need an invigilator?

In the following time, everyone had no questions and the examination room was unusually quiet.

After solving two questions, Qin Zhouping really couldn't solve any more and had to give up temporarily because he was feeling very anxious.

There are three urgent things for people!

After he came back from squatting in the pit, he wanted to continue to complete the next questions, but even after three hours, he still hadn't found the answer.

In fact, it wasn't just him. Others also completed one or two questions. Most of them just wrote the word "solution" and couldn't write any more.

It's so hard!

"Everyone can put down their pens and stop answering questions. Students who have solved one or more questions can hand in their answers. Other students can leave the classroom."

On the podium, Wang Duoyu stood up and said so.

The classroom suddenly became lively. Many students had sad faces, as if their confession had been rejected, and their faces were full of resentment.

Many students passed by the podium and complained to Wang Duoyu before leaving the classroom:

"Professor Wang, you're too harsh! These ten questions are all very difficult. I can't answer any of them. I don't think anyone can get 60 points, right?"

"Yes, Professor Wang, there is absolutely no difference between an open-book exam and a closed-book exam. It's even worse than a closed-book exam."

"It was so hard. The exam lasted three hours and there were ten questions in total, and I only finished seven. Professor Wang, please don't give such difficult questions next time."

Someone was being too Versailles, which immediately caused strong dissatisfaction among other students, and they all stared at the person who was pretending to be cool.

Upon hearing this, Wang Duoyu looked at everyone with a smile, but had no intention of talking to them.

Although he did not go down to check on everyone's exam results, he only needed to glance at the podium to know who had answered the questions seriously.

The ten questions on the blackboard are all related to topology. If you can't answer any of them, then you are really not qualified to attend his class.

After all, this is not a basic course, but a course about the Poincare conjecture in four-dimensional space.

If the report is a condensed version, then the course he is currently teaching is an expanded and complete version. The content will be so detailed that anyone with a PhD in mathematics can understand it.

Soon, Wang Duoyu received nearly one hundred answer sheets.

After seeing these answer sheets, Wang Duoyu immediately picked up a red pen and started correcting them.

Jian Xianglan, Zhu Hanting, Yuan Jigang and others who were originally preparing to leave did not leave after seeing Wang Duoyu's actions. They all stayed and surrounded the latter to see how he would score.

There is no need to ask for the result. Each question is worth 10 points, and the total score is 100 points.

Needless to say, those who couldn't answer any questions got no points at all. Those who answered one or two questions could only get a few points or a dozen points at most, or even zero points.

After all, there are always people who just write and copy randomly.

When Wang Duoyu saw this answer, he showed no mercy and circled a zero on the other person's test paper.

"Zero points? Duoyu, you're too cruel, aren't you going to give me any marks for the paper?"

Lou Jianguo was astonished, and Yuan Jigang and the others were trembling with fear, because some of them had answered all ten questions, but they were confused in answering the last few big questions and had no answers at all.

Wang Duoyu ignored Lou Jianguo's opinion and continued to mark the papers.

In less than thirty minutes, he finished grading the test papers. Only three people scored full marks, namely Zhu Hanting, Jian Xianglan and Rong Guangxia, while eight people scored 90 points or above.

Only thirty-four people scored above 60 points, and the rest scored below 60 points.

Looking up, it seemed that no one had left, so Wang Duoyu stood up and said:

"The test papers have been graded. I've noted down the students who scored 60 or above. There are 34 of them in total. However, excluding a few international students, the total number is 32."

"So starting tomorrow, the thirty-two of you who have achieved a passing score can come to my classroom to attend the class. Students who scored fifty points or above can also audit."

"However, students with scores below 50 don't need to audit the class. It's pointless. I doubt you'll understand. Don't waste your time."

After saying that, Wang Duoyu left.

Behind him, a group of people began to wail.

Qin Zhouping didn't expect that he didn't even have the qualifications to attend the class as an auditor. Damn!

The gap between people is too big, isn't it?

In dormitory 303, Zhu Hanting and the other seven had returned. Zhu Hanting looked a little hesitant. Yu Xinyao asked curiously:
"Old Zhu, didn't you get full marks? Why do you still have that expression?"

"That's right, Lao Zhu, you are really awesome. You actually got full marks. I only got 75 points. The next three questions are really hellishly difficult."

Tian Maohua also echoed.

In their dormitory 303, except for Yuan Jigang, the other six people's mathematical talents are not bad.

Even Yuan Jigang scored 55 points this time and got the qualification to audit the class.

So to be honest, Yuan Jigang’s mathematical talent is not that bad.

The candidates for the college entrance examinations in 1977 and 1978 were actually not much different, because there was only half a year between them. Many people only reviewed for half a year, or even just a few months.

Therefore, the qualifications of these two classes of students are not bad.

"What's the point of getting a perfect score? I can't continue attending Duoyu's classes anymore, oh no"

Zhu Hanting sighed and said this. Yu Xinyao laughed and said, "It's okay. We'll listen for you. You're leaving for Beijing the day after tomorrow. When you go to the United States, study hard and see for us how developed capitalist society is."

"The United States is developed, that's their business. It has nothing to do with us. I regret signing up to study in the United States now."

Hearing Zhu Hanting's words, Lou Jianguo and the others twitched their lips, and Rong Guangxia couldn't help but say sourly:

"Old Zhu, if you keep pretending like this, do you believe we will deal with you right now?"

Yuan Jigang immediately looked at Zhu Hanting with ill intention. The latter shuddered and shook his head quickly.

However, he felt more and more depressed.

To be honest, he was really in a dilemma. On the one hand, he wanted to stay, but on the other hand, he wanted to study in the United States.

Ugh!
No matter how Zhu Hanting struggled, what was coming would come.

The next morning, Zhu Hanting, Rong Guangxia and others went to the teaching building of the Department of Computational Mathematics for class, but Jian Xianglan did not come. She probably had something to do.

Xue Xiaoling was very active. She was the first to arrive at the classroom and took the initiative to wipe the blackboard and keep the podium clean.

In fact, she knew that Wang Duoyu was already married, and her previous plans had fallen through. Now she could only rely on herself to achieve the highest level in the field of mathematics.

But deep down, she still hoped that Wang Duoyu would get divorced and then get married for the third time.

This expectation is reasonable, because Wang Duoyu and his wife live apart, so their relationship is indeed unstable.

Therefore, in some cases, Xue Xiaoling still has the opportunity to take advantage of the opportunity, but she has her own bottom line and principles and will not take the initiative to destroy Wang Duoyu's marriage.

Otherwise, with Wang Duoyu's intelligence, he would not choose her even if he got divorced.

There were more than 40 students attending today's class, including many who were auditors, and even some who had scored more than 30 points in the exam yesterday. These students were asked to leave by Wang Duoyu.

"If you want to audit the course, then work hard. Topology is not something that everyone can learn."

Wang Duoyu earnestly counseled these students several times. Although his tone was harsh and hurtful, he had no other choice. Mathematics is like this. Those who don't understand it will never understand it.

Two hours later, the course ended successfully. Wang Duoyu picked up the aerospace book, stood up and walked out of the classroom.

He didn't need to bring any textbooks or papers to class. The reason he brought aerospace books was because he needed to compile aerospace textbooks, and he had to finish reading those books before he could continue compiling.

In the afternoon, Lin Dehong came and this time he brought a lot of books.

"Duoyu, the higher-ups have approved your previous application. Here, these are the documents you need. It's best for you to just look at them yourself and not show them to anyone else."

Lin Dehong pointed at the two large boxes and said:
"Once you have sorted out the information and compiled it, you must submit it to me immediately. The superiors said that we need to wait for them to review it before we can submit it to Harbin Institute of Technology for review. Otherwise, it will be considered a data leak."

"It's you, and this is Harbin Institute of Technology. If it were anyone else, they wouldn't be able to produce this information."

Upon hearing this, Wang Duoyu nodded silently and flipped through the information in his hands.

These materials were all applied for by him from the army before. They were information related to aircraft and missiles. This part was very critical.

He wanted to compile a book that encyclopedias of the world's aircraft and missiles, so that students majoring in aerospace, college students, and even the entire society would know these basic common sense.

In this day and age, it is very difficult to obtain some information.

As a result, information gap always exists, but Wang Duoyu traveled from the future. In that era, information was overwhelming and it was easy to get the information you wanted.

This caused him to be very uncomfortable after traveling through time, and even now, he is still a little uncomfortable with it.

Of course, no matter how uncomfortable he is, there are some things he really wants to do.

"Okay, now that we're done with business, how about a drink later? I got two bottles of Wuliangye today, hehe, produced five years ago."

After hearing Lin Dehong's words, Wang Duoyu did not refuse.

Lin Dehong really had nothing to say about him. No matter what request he made, Lin Dehong would try his best to satisfy it.

Of course, Wang Duoyu is also a person who knows how to return a favor. With his hard work and help, Lin Dehong was promoted smoothly.

He used to be a staff officer, and now he is a supervisor. According to the job level, he should have two bars and three stars on his shoulders, but there is no such thing as military rank now, as it has not been restored yet.

Anyway, regardless of anything else, Lin Dehong is now the leader with real power and can barely be called the chief.

It is said that people feel refreshed when good things happen to them. Lin Dehong has just been confirmed by the higher authorities and has not officially taken up his post yet. Anyway, he can take office after the procedures are completed.

In the evening, in a small room in the cafeteria of a unit in the center of Bingcheng City, Lin Dehong brought Wang Duoyu here to eat, but they were not the only two there, there were actually other people there.

"Duoyu, let me introduce you. This is Lao Fei, full name Fei Qidong. He's a regimental commander and used to be the most formidable on the plateau battlefield."

"This 'young man' with prematurely gray hair is Gong Wenjie. We all call him Little Gong. He will take over my previous position."

"And this guy's called Zhang Shouhua. You can definitely call him Old Zhang. He used to be a buddy of ours, but later moved to another job. He now works for the Bingcheng government. If you have any trouble in Bingcheng, just go find him. If he dares to shirk responsibility, call me and I'll take care of him."

Following Lin Dehong's introduction, Wang Duoyu shook hands with these people one by one, and that meant they were acquainted with each other.

However, from the expressions of Zhang Shouhua and others, Wang Duoyu saw some overly enthusiastic flattery.

I don't know if it was his imagination.

After all, any one of these three is a leader.

Even among everyone present, Lin Dehong has the highest position. After all, two bars and three stars are not an ordinary level. Especially in the current context of military layoffs, he can still go against the current. He is truly not an ordinary person.

But Zhang Shouhua, Fei Qidong and Gong Wenjie, given their social status and positions, should not need to please Wang Duoyu at all.

After the warm greetings, the warm-up session immediately began, which actually made the event even more lively.

After three rounds of wine and five dishes, the atmosphere in the small room became even more lively.

Wang Duoyu raised his hand to check the time and decided to go back to school.

Lin Dehong did not try to persuade him to stay, but instead arranged for Xiao Fang to send Wang Duoyu back to school.

After Wang Duoyu left, the slightly drunk state of Zhang Shouhua and the other two immediately disappeared.

"Old Lin, we've already met him. This Little Wang isn't as mysterious as you say."

Hearing Fei Qidong's words, Gong Wenjie immediately echoed:
"Yes, Lao Lin, we are all family members in this room now. If you have anything else to say, please speak up immediately. Otherwise, don't blame us for taking turns to get you drunk."

Zhang Shouhua, who was relatively shrewd, just smiled and said, "Old Lin will definitely keep us in suspense. Haha, he must not have drunk enough. Come on, let's toast him a glass."

However, Lin Dehong reached out to stop the three of them from toasting, and the smile on his face faded a lot. He said:

"I've told you before that my promotion has a lot to do with Comrade Wang Duoyu. You all know now that it's unlikely that I'll be able to move up in the next five, or even ten years."

"But you still have a chance, a very good chance. If we weren't close friends, I wouldn't have introduced him to you."

"Wang Duoyu may seem young, but he's actually incredibly talented and incredibly capable. You've all read the news, so you must know a lot about him. Without going into details, the opportunity is right in front of you; it depends on whether you can seize it."

"He's already started compiling aerospace materials. I suspect he might be planning to conduct aerospace research projects in the future. That's all you need to know. I don't know anything else."

After hearing Lin Dehong's words, Zhang Shouhua and the other two suddenly had question marks on their faces.

What the hell?

Wang Duoyu is busy with aerospace research projects, what does it have to do with them?

Is it possible that they can get some share of this credit?
Seeing this, Lin Dehong did not continue to speak. After all, whether they could understand it or not was their own business.

It can be said that he introduced Wang Duoyu to Zhang Shouhua and the other three simply because he hoped that they could cooperate with each other.

If we can cooperate, it will be mutually beneficial and progress.

The next day, Wang Duoyu came to the school gate. He wanted to see Zhu Hanting off today because the latter was going to the capital.

"Old Zhu, take care on your journey!"

At the school gate, Zhu Hanting forced a smile, Rong Guangxia and others were full of envy, and only Wang Duoyu looked calm.

I'm just going to the United States, not anywhere else.

However, to be honest, Wang Duoyu has never studied abroad. In his previous life, he was only on business trips abroad and did not stay for a long time, so he does not have a very deep understanding of foreign countries.

Of course, the situation in China will only get better.

Jian Xianglan glanced at Wang Duoyu, then suddenly walked up to him and handed him a book:

"Professor Wang, I will definitely catch up with you!"

"I wish you a safe journey, and that you will still be young when you return."

Like Zhu Hanting, Wang Duoyu also gave the other party a notebook with this sentence on it, and everyone was the same.

After watching Zhu Hanting and the others get on the car, Wang Duoyu turned around and went back to the teaching building.

The departure of Zhu Hanting and other international students made Rong Guangxia and the others feel a little fluctuating, but Wang Duoyu didn't say anything.

That afternoon, two letters were delivered from the Security Department.

Ever since he mailed the three papers proving the Poincare conjecture from an off-campus post office, which attracted the attention of school leaders, his correspondence has been taken over by the security department.

Whether sending or receiving, the Security Department will come to the teaching building of the Department of Computational Mathematics.

Although this has invisibly reduced Wang Duoyu's workload, he has also lost a lot of time for fun and exercise.

Because he spends most of his time sitting throughout the day, sending and receiving letters is the time he usually spends taking a walk, but now he doesn't have that time anymore.

So he had to find time to take a walk.

I received two letters today. One was from Liu Xiaoli, who I hadn't contacted for a long time. She described her recent situation and then asked how Wang Duoyu was doing recently.
She also said that she saw the reports in People's Daily and was very happy for him.

After reading the letter, Wang Duoyu was silent for more than ten minutes.

What does Liu Xiaoli want to do?

Just break up, be decisive, isn't it?
The second letter was written to him by Su Buqing, the editor-in-chief of the Journal of Mathematics, regarding the review of a paper by Lu Jiaxi.

When he saw Lu Jiaxi's name, a hint of surprise flashed across Wang Duoyu's face and he raised his eyebrows: Could it be the math genius in his memory?

Without thinking too much, Wang Duoyu immediately opened the paper. Just by looking at the title "Existence Theory of Decomposable Equilibrium Incomplete Block Design", he was sure that the author was the mathematical genius he remembered.

It’s really Lu Jiaxi himself!

Wang Duoyu spent two hours reviewing the paper and found it completely suitable for publication. It is a very good theoretical research paper.

So he picked up paper and pen and wrote back to Su Buqing.

But half an hour later, he looked at the words on the reply letter, was silent for a while, suddenly stood up and went to Director Wu Congxin's office.

"Director Wu, could you please take a look at this paper?"

The latter was a little surprised and delighted, and said with a smile:

"Professor Wang, you wrote another paper? Aren't you teaching recently? How do you still have time for scientific research?"

"Director, this is not the paper I wrote. Please read it first. I will tell you after you finish reading it."

More than an hour later, Wu Congqin finished reading the paper. Although he had not carefully argued it, he believed Wang Duoyu.

So he asked Wang Duoyu's purpose with a smile.

"Director Wu, this teacher is a genius. I want him to come to our Harbin Institute of Technology, so I need you to find Secretary Li and ask him to help transfer this teacher to our school."

When Wu Congqin heard Wang Duoyu's words, he was shocked, and then he nodded happily and agreed.

Wang Duoyu has just briefly explained Lu Jiaxi's information. Wu Congqin trusts the former, so Lu Jiaxi's information should not be false.

Since it is not fake, there is absolutely no problem in transferring Lu Jiaxi to Harbin Institute of Technology.

In the principal's office, Liu Deben quickly learned the news and immediately took action.

Liu Deben never compromises on any request made by Wang Duoyu.

Moreover, according to Wang Duoyu, if Lu Jiaxi could come to Harbin Institute of Technology, it would definitely enhance the mathematical strength of Harbin Institute of Technology.

In the Steel City outside the Great Wall, it is July 1979. It is summer vacation now. Although Lu Jiaxi is on summer vacation, he still does not relax.

Every day after dinner, he would return to his room and continue his scientific research work at his small desk.

His wife Zhang Shuqin is very supportive of his scientific research, but she is also worried about his health. She always persuades him to take a walk after dinner every day and stay up no later than midnight.

Unfortunately, Lu Jiaxi was studying difficult mathematical problems, and it was difficult to stop once his ideas started. Therefore, he often ignored Zhang Shuqin's opposition and just worked hard.

That evening, the middle school leaders brought two leaders from the Gangcheng Education Bureau.

"Teacher Lu, do you know anyone at Harbin Institute of Technology?"

At this moment, Lu Jiaxi was completely confused. Harbin Institute of Technology was a very unfamiliar school to him.

Although he worked in Bingcheng for many years in the early 1950s, he had never been to Harbin Institute of Technology, let alone met anyone there.

Seeing his bewildered look, the leader became even more confused.

"Leader, is there anything I can help you with?"

Hearing Lu Jiaxi's question, the middle school principal couldn't help but exclaimed:
"Teacher Lu, Mr. Lu, you are going to be successful. Harbin Institute of Technology called and asked you to report there."

It is such a magical thing to be promoted from a middle school teacher to a university teacher.

The leader of the Gangcheng Education Bureau had already produced the telegram and said:

"Teacher Lu, Harbin Institute of Technology has sent a telegram informing you that they hope you can come to Harbin Institute of Technology to discuss this matter in detail. They currently have a vacancy in the Department of Computational Mathematics at Harbin Institute of Technology. After learning about your paper."

"According to the requirements of Harbin Institute of Technology, our Education Bureau has prepared train tickets and food coupons for you. The train leaves tomorrow afternoon."

After hearing what their leader said, Lu Jiaxi and his wife Zhang Shuqin looked at each other in surprise. Is this really Harbin Institute of Technology?

Zhang Shuqin was very happy because if she taught at a university, she would definitely get a higher salary, right?

Four days later, Lu Jiaxi finally met Wang Duoyu in the director's office in the teaching building of the Department of Computational Mathematics at Harbin Institute of Technology.

"Professor Wang, I heard from Director Wu that you recommended me to teach at Harbin Institute of Technology, is that correct?"

Looking at Wang Duoyu's face that looked too young, Lu Jiaxi, who was actually 44 years old but looked like he was in his 50s or 60s, was dazed for a moment, but still called him Professor Wang honestly.

During the conversation with Wu Congqin just now, Lu Jiaxi already knew the identity of Wang Duoyu, who is a professor at Harbin Institute of Technology.

Wang Duoyu smiled and nodded, saying:

"Teacher Lu, you're right. I was the one who recommended you to the school. I know you have a lot of questions, but I want to say that the theoretical paper you wrote on block design is excellent."

Lu Jiaxi's face lit up with joy, but he became even more confused:
"Professor Wang, I remember I submitted my paper to the Acta Mathematica Sinica in May of this year. This journal should be from Fudan University, right? How did you know?"

"Because Editor-in-Chief Su wrote to me and asked me to be a reviewer."

Half an hour later, Lu Jiaxi finally figured it out and suddenly became very happy.

So, he agreed to join Harbin Institute of Technology and become a member of the teaching team of the Department of Computational Mathematics of Harbin Institute of Technology. His salary was based on the ninth-level standard, that is, the lecturer's salary, which was 82.5 yuan per month.

This salary is very high, especially for Lu Jiaxi, a middle school teacher.

But after joining Harbin Institute of Technology, he will not participate in any teaching, but will focus on scientific research projects.

"Teacher Lu, once you've dealt with your personal affairs, please come and report to me. I will then assign you research tasks."

After hearing what Wang Duoyu said, Lu Jiaxi looked at the other's young face. Even though he had already introduced the fact that the other party was very awesome in his mind, he still felt a little uncomfortable.

At Lu Jiaxi’s age, he could be Wang Duoyu’s father.

In the end, he still had to follow Wang Duoyu's arrangements, and of course he felt a little uncomfortable.

In fact, this was also a helpless move for Wang Duoyu.

Who made it so that many people in this era do not agree with Lu Jiaxi's scientific research results?
Otherwise, with the "Collection of Non-intersecting Steiner Ternary Systems" that Lu Jiaxi has now brought out, why is he just a physics teacher at Gangcheng No. 9 Middle School?

In China, there are not many experts in the field of combination design, and even if there are, they are not well-known.

That's why Lu Jiaxi is in such a mess now. He is just a middle school teacher.

If Wang Duoyu suddenly asked Lu Jiaxi to apply for a scientific research project on his own, he would most likely be rejected by Wu Congyin and others.

After all, Director Wu would definitely be severely scolded by his superiors for spending 82.5 yuan a month to support an idle person who specializes in theoretical mathematics.

Harbin Institute of Technology is not the Institute of Mathematics of the Chinese Academy of Sciences, and it does not have that much money to support such "idlers".

The reason why Li Rui and Liu Deben were willing to spend such a huge amount of money to support Wang Duoyu was simply because the latter solved a popular mathematical problem such as the Poincare conjecture, which had a great influence in the international community.

In the context of reform and opening up, scientific researchers like Wang Duoyu are of course talents that the country urgently needs, which is why Harbin Institute of Technology is so willing to hire them.

But Lu Jiaxi's research is on theories related to Steiner's collections, which is a bit unpopular.

In this case, Wang Duoyu could only let Lu Jiaxi stay in his scientific research team. This was also a temporary transitional solution. He believed that Lu Jiaxi would not let him down.

After Lu Jiaxi's matter was settled, Wang Duoyu received news from the capital at this time.
