Top academic

Chapter 130 This person is closer to me than my own grandson!

Huaxia, Huaqing University, Qiuzhai.

Yuan Zhengxin was in the office reviewing the plan for the Elite Class. The old man read very slowly, checking every detail very carefully, and also considering whether the curriculum needed to be adjusted and how to maximize the teaching staff.

The old man is the same age as the Republic. It is easy to imagine how difficult it was to come out of that era of poverty, not to mention that Yuan Lao's family was very poor when he was young.

It is easy to imagine how difficult it is for students from poor families to succeed.

It can be said that it is because of his extraordinary talent and extraordinary efforts that he has achieved his current status.

The experiences in his childhood have also made the old man slightly stubborn, and he cannot tolerate any injustice. His ideas are often incompatible with the young people of the new era who are more willing to express their individuality. He may even be considered old-fashioned, so he often comes up with some actions and regulations that are criticized.

In fact, what the old man wants to do is to tell all the young people that building a country is not enough to be cynical. The post-90s and post-00s are the hope of the Chinese mathematics community! Let Chinese mathematics catch up with the world, and it is placed on the shoulders of two generations.

Young people cannot just sit and watch the country's mathematics lag behind in the world. China is on the road to rising national strength, and if mathematics wants to keep up with the pace of national development, it must study hard and work hard like its predecessors, so that the Chinese mathematics community can have a say in the world!
In fact, if we consider that the old man is already 76 years old, and he still insists on being at the forefront of mathematics education, it is enough to be admired. There are not many people who can do this throughout history. After all, this really requires extraordinary passion and perseverance.

The old man was thinking about whether he needed last year's feedback to make some minor adjustments to the curriculum of this year's Elite Class. Suddenly, he heard footsteps outside the door, followed by a knock on the door. The old man took off his glasses and said loudly, "Come in."

The office door was pushed open and Li Lixing walked into the old man's office.

After hanging up Ronald's video, Li Lixing wanted to call Yuan Lao directly to inform him, but after thinking about it, he decided to come in person.

For some things, expressing gratitude in person can better show your sincerity.

"Professor Li is here. Please sit down and have some tea." When Yuan Zhengxin saw that it was Li Lixing, he stood up and a smile appeared on his face.

Li Lixing quickly took two steps forward and said, "Mr. Yuan, please sit down and don't worry about me. To be honest, I came here just to thank you. After thanking you, I have to go back quickly to make plans for the next stage and discuss it with everyone at the group meeting tonight."

"Thank me?" The old man was a little confused.

Li Lixing immediately explained: "Of course I have to thank you. If you hadn't recommended Qiao Yu to join our large research group, we might still be troubled by that problem. In fact, today Qiao Yu successfully proved a theorem that has troubled our research group for half a year!
I just deduced Qiao Yu's proof with Professor Ronald, and we both agree that Qiao Yu's proof is completely correct. Professor Ronald also asked me to apologize to you, because he thought you had selfish motives in recommending Qiao Yu to join our research group. "

Yuan Zhengxin looked at Li Lixing, thought for a moment, smiled, and said, "Actually, what Ronald said is right. I had selfish motives when I introduced Qiao Yu to your research group. I wanted him to see the world with you and understand the way of international research collaboration.

Although I expected him to make some achievements in the research group, I never thought he could achieve this level. Professor Li, you are not helping Qiao Yu to make some achievements to make me happy, right? "

Li Lixing pulled the corner of his mouth and smiled bitterly: "Mr. Yuan, you really think too much this time. To be honest, if I wanted to do this, I wouldn't choose this time. In such a short time, I doubt he has even read all the information I gave him.

Moreover, he had hardly communicated with us about this issue during this period. He did raise some opinions during the group meeting, but most of them were methods we had tried before. Today, I received an email from him for the first time. It was the proof process of this proposition. "

Yuan Zhengxin's expression turned serious, and he said, "He really solved the problem you encountered recently by himself? Do you have the original manuscript? I'd like to take a look."

Li Lixing had long anticipated that the old man would definitely make this request and was well prepared.

He placed the bag on the old man's desk, took out a stack of manuscripts with a printed paper on it, and handed them to Yuan Zhengxin: "The printed copy is Qiao Yu's proof process. He only provided a brief idea. These manuscripts were just completed by Professor Ronald and I."

"How about you sit down for a while?"

"No, no, you just watch first. I really have to be busy. In the afternoon, I plan to let those useless students take a look at Qiao Yu's proof. Alas, we are all students, but the gap is too big."

Yuan Zhengxin, who always advocated strict requirements for students, heard this and said from the student's perspective, "Haha, we can't be too harsh on students. After all, children like Qiao Yu are a minority."

"Oh... I understand, but there's nothing we can do! Every time a genius appears in an era, how can other mathematicians keep up with the genius if they don't push themselves?" Li Lixing said with emotion.

When mathematician Peter Schulz was 24 years old, he became a W3 professor at the University of Bonn. When he was 30 years old, he won the Fields Medal. How many Western mathematicians envied him? Now there is a student with such potential around me. I understand that feeling.

Li Lixing even suspected that Qiao Yu didn't need to be 24 years old. Maybe after he became an adult, he would be given the title of full professor by Yanbei directly, and no one would complain about it.

One independently completed paper has been confirmed to be published in Ann.Math, and another has been submitted to Invent. Math. Given the influence of the geometric Langlands conjecture and Qiao Yu's wild imagination, Li Lixing feels that there is a high probability that the paper will be published.

This paper from their research group will definitely be published in one of the four top journals within two years, and it now seems that Qiao Yu will at least be the third author.

Next, I will give a 30-minute report at the World Congress on Algebraic Geometry.

Apart from other things, even if Qiao Yu did nothing in the next two years, no one would be able to complain if he was promoted to associate professor at Huaqing University based on his achievements this year. The only thing that affected Qiao Yu now was his age.

A sixteen-year-old university professor is so outrageous that it may even spark controversy in the legal community.

For example, is this about valuing talent or employing child labor?
It feels difficult to define.

"Oh, so...a genius!" Yuan Zhengxin also sighed.

However, what the old man was thinking about at this time was not Qiao Yu's talent, but Qiao Yu's efforts.

How many children in the gifted class can sit there quietly and concentrate on reading for an entire afternoon like Qiao Yu? How many of them can fill several pages with their handwritten manuscripts?
Whenever Qiao Yu came to this office, it was always like this, without exception.

The noise outside didn't affect him at all.

So these professors are still short-sighted. They just think Qiao Yu is a genius, but they don’t delve into the sweat and hard work behind the genius!
In this world, apart from the capital gained through blood ties, is there any glory that can be easily obtained?
When a group of students complain about having one less day of rest, have they ever thought about the people who are more capable than them and are still working hard silently?
Li Lixing saw that the old man was a little sentimental, so he said goodbye at the right time: "Mr. Yuan, I'll be busy now."

"Okay, go ahead." The old man nodded slightly.

After watching Li Lixing turn and leave, the old man put on his glasses again and began to examine Qiao Yu's proof process and the supplementary process of Professors Li Lixing and Ronald.

The process is wonderful!
But what is most striking is Qiao Yu's six lines of concise and exquisite argument.

It directly constructs an exquisite and rigorous logical framework, showing the profound relationship between global functions and transformation groups.

By defining the invariance of the Whittaker layer, the properties of the feature layer are clearly introduced, and its invariance is revealed through mapping. Using the categorization contraction principle, the endomorphism property of the mapping is proved, and finally the global function is connected with the endomorphism of the Whittaker layer, showing the harmonious unity between mathematical structures.

No wonder Li Lixing emphasized Qiao Yu's talent, because the most valuable thing is the mathematical thinking he embodied, which is abstract and concise, like a sword that directly penetrates the core of the problem. Even the old man couldn't help but applaud.

After reading it, the old man picked up his phone and took a look.

The little guy who likes to report everything has achieved such great results, but no one asked him for credit?

Ha... Is he afraid that I will praise him again and make him proud?
I wanted to ask a question on WeChat, but suddenly an idea came to my mind, and I stood up from my seat and walked out of the office.

"Arrange a car to take me to the International Mathematical Research Center across the street."

"Ah? Mr. Yuan, Yanbei International Mathematics Research Center?"

"Are there others on the other side?"

"Well...should we notify the other side first?"

"No need, I'll just go over and take a look."

The old man waved his hand and refused.

If Tian Yanzhen can come to Huaqing, why can't he go to Yanbei?
……

Half an hour later, Mr. Yuan appeared at the door of Yanbei International Center for Mathematical Research.

Walking into the gate of the Mathematical Research Center, Yuan Zhengxin hesitated for a moment.

Qiao Yu did say that he lived in a corner of a research center, but he didn't say the exact location.

Just when I was considering whether to call this guy to pick me up, I was recognized by someone.

"Mr. Yuan?"

Yuan Zhengxin glanced sideways and saw that the man looked like a young professor.

"Yes, it's me. May I ask who you are?"

"Hello, Professor Yuan. I'm Xue Song, an associate professor at the Mathematical Research Center."

Yes, the professor who recognized Yuan Zhengxin was Xue Song.

He was just about to go out to do something, and as soon as he arrived at the door, he saw Yuan Zhengxin standing at the gate.

"Oh, Professor Xue, hello. I heard Qiao Yu mention you. Were you at Yujiang University?" Yuan Zhengxin nodded and asked.

"Yes, I was transferred here this year." Xue Song answered nervously.

He also didn't know how Qiao Yu introduced him to the old man in front of him.

If this kid Qiao Yu happened to tell Xue Song the reason why he wanted to be Tian Yanzhen's disciple, Xue Song felt that the old man probably wouldn't like him very much.

Of course, Xue Song felt that this could not be entirely blamed on him.

At that time, he only had Tian Yanzhen's contact information in his phone, but not Yuan Zhengxin's. If he had both, he might have made the same choice as Qiao Yu, sending two copies of the paper, and then seeing which big shot would be interested in such a student.

Fortunately, the old man didn't look strange. He just smiled and said, "Yes, I heard from Qiao Yu that you gave him a lot of advice. You took the trouble."

Xue Song quickly replied: "Actually, Qiao Yu doesn't need any instructions. I just helped him plan his future. By the way, are you here to see Academician Tian? I'll take you there?"

Yuan Zhengxin shook his head and replied, "No, I just came to see Qiao Yu. I heard from the children that he lives here, so I came to see what his living environment is like. If Professor Xue is not busy, you can take me to see Qiao Yu."

"No hurry, no hurry, just follow me."

After saying that, Xue Song took the old man towards the building in the corner of the research center where Qiao Yu was.

"By the way, didn't you inform him before you came?" Xue Song asked as he took the old man there.

If he had been notified in advance and this guy didn't come out to greet him, he would be too arrogant. He would have to criticize this guy severely later.

"No, I just suddenly became interested. I haven't come to see this place since it was built." The old man answered while looking at the scenery around him.

"Oh, I don't know if he is here. Qiao Yu will choose to attend some classes recently."

"It's okay, let's go check it out first, and then we'll talk if she's not here."

"Ok."

The yard was so small, and even though Xue Song deliberately slowed down his pace, it only took him a few minutes to reach the building where Qiao Yu lived.

Seeing through the window that the young man in the room was reading a book seriously, Xue Song breathed a sigh of relief.

It’s good that this kid didn’t go out.

Even though the old man certainly said that he didn't care, but after coming here with great difficulty and coming back empty-handed, he would still be somewhat disappointed, right?
"It's right here." Xue Song paused and pointed at the hut.

Yuan Zhengxin nodded. In fact, he had just seen it. Although it was not in his office, he could see through the window that Qiao Yu was still so serious when reading.

He didn't go to class and chose to read on his own without any supervision, and he was still so self-disciplined.

Especially when you have just made some achievements, you can still maintain this state of mind, not taking credit for it, not being proud, and being calm and natural.

Still maintain the thirst for knowledge and ambition...

Even some professors at Huaqing University cannot compare with his ambition.

He was so proud of his achievements that he held a celebration banquet and even invited him here...

How can the gap between people be so big?

……

Qiao Yu, who was reading a book in the house with great interest, would never have imagined that his master outside the house was praising him a thousand times in his heart.

I even dislike some people even more.

Really, he had been planning to go out today to celebrate for solving a difficult problem, but Yu Wei suddenly popped up and showed off the strength that a rich second-generation should have, which made him give up the idea of ​​relaxing.

After all, people need to have a balance between tension and relaxation.

But many times it's just a coincidence.

Especially for an old man like Yuan Zhengxin, his eyes that see through the world have long been tired of hearing all kinds of assurances. Most of the time, he only believes what he sees, whether it is good or bad.

"Bang bang bang."

The sudden knock on the door woke Qiao Yu from his deep reading. He subconsciously looked out the window, then immediately stood up and opened the door.

"Hey, Master, Professor Xue, how come you two are meeting each other?"

Opening the door, Qiao Yu asked in surprise.

It was common for Old Xue to come to his place, but it was different for Old Yuan.

This can be seen from the fact that Senior Brother Chen has been in the research center for five years and has never met his own master once. This shows how rare this situation is.

"Mr. Yuan came to see you. I happened to meet him at the gate and showed him the way." Xue Song explained.

"Oh, I see. Grandmaster, Professor Xue, please come in." Qiao Yu quickly vacated his seat.

"I just want to bring Mr. Yuan here. I have other things to do in the afternoon, so I won't go in. You just need to take good care of Mr. Yuan. Mr. Yuan, I'll be leaving first." Xue Song said hurriedly.

The master and his apprentice were chatting happily, and as an outsider he had nothing to do, he didn't intend to get involved.

"Well, thank you, Professor Xue."

"You're welcome."

After saying that, Xue Song turned and left.

After turning the corner, he thought for a while and took out his cell phone to call Tian Yanzhen. After the call was connected, he told the other party that Mr. Yuan had come here specifically to visit Qiao Yu.

"Oh, I see. I'm in a meeting outside. I'll see if Mr. Yuan has left when I come back."

"Well, I'm just telling you."

"Thank you, Professor Xue."

After hanging up the phone, Xue Song suddenly felt that he seemed to be influenced by Qiao Yu...

He seemed to be disdainful of doing these things before.

But ever since I met Qiao Yu, seeing this young genius calling him Director Tian and Grandpa Master all the time, a string in my head seemed to suddenly loosen.

Think about it, such a talented young man, who spared no effort to coax the boss, the little achievements he has made are nothing! What's so noble about it? !
……

In the room, the boy was scratching his head.

"Um, Grandpa, I don't have any tea leaves here. Um...how about you wait for a while and I'll go to Director Tian's office and steal a bag of his good tea to make you a cup?"

Just one sentence made the old man laugh happily: "Haha, no need, no need, I just came to see how you are living, and I will go back after chatting with you for a few minutes. Grandpa also has a lot of things to do."

Qiao Yu said seriously, "I think you should leave those trivial matters to others. You just need to grasp the general direction. Huaqing has so many professors. At your age, the most important thing is to take care of your health."

"Don't worry, I'm in good health. I'll definitely live another ten or eight years. No matter what, I want to see you receive the Fields Medal with my own eyes." The old man said happily.

Qiao Yu nodded and said seriously, "Don't worry, Grandpa. I will wait until I am forty to receive the award."

The old man raised his finger and pointed at Qiao Yu, criticizing him lovingly: "What nonsense! As for you, I think 21 years old is enough! You will definitely get it."

This shows that he will achieve great success before the next World Congress of Mathematicians.

Qiao Yu smiled but didn't answer. It wasn't up to him to decide whether he could take it or not. He didn't think about things that far ahead.

He is still young and there is no rush to think about these things.

"Your place is indeed a little small. What is Tian Yan really up to? In such a big yard, you can't find a proper suite? There's not even a bathroom. The conditions are too harsh. Well, since you are a joint training student now, why don't you just live in Huaqing? I'll find a way to make room for you."

Yuan Zhengxin looked around the single room where Qiao Yu lived and said in a domineering tone.

"Ah? Grandpa, this place is actually not bad. The bathroom is on the second floor next to it, and Senior Brother Chen also helped me get a solar water heater, so it's very convenient for my life. I promised Director Tian before. How about this? I'll study here for two years, and then I'll go to Huaqing. The most important thing is, I don't think I'm old enough to enjoy it yet."

Qiao Yu said quickly.

In fact, it didn't matter to him where he lived, but his student status was now at Yanbei University, and he always felt something was wrong when he moved to Huaqing University.

Yuan Zhengxin glared at Qiao Yu, then sighed and said, "Well... okay, then I'll call Tian Yanzhen. My grandson can't be treated like this while studying in Yanbei. By the way, what book were you reading just now?"

Qiao Yu picked up the book "Principles of Algebraic Geometry" on the desk and handed it to the old man.

"It's this book, Principles of Algebraic Geometry, that you and Director Tian both recommended to me."

The old man took the book handed over by Qiao Yu, flipped through it casually, and said, "Well, this algebraic geometry book co-authored by Philip and Joseph can be said to be a classic in the field of algebraic geometry. The discussion of algebraic clusters and complex geometry is very in-depth. It is worth your careful reading."

After that, he casually said, "Professor Li came to me today to thank me for introducing you to his research group. I was puzzled for a while. If I don't come to ask you, are you going to explain to me what's going on?"

"Oh, about this!"

Qiao Yu immediately smiled and said, "Grandpa, I have indeed been thinking about this problem for a while, but I still haven't figured it out. It was a coincidence today. I went to the Philosophy School to take a class, and Brother Chen happened to call me again. Guess what? Suddenly, I got an inspiration.

As a result, I didn't even finish lunch before I ran back to write down the proof I had thought of at the time and sent it to Professor Li. Although I think there is definitely no problem with the idea, Professor Li hasn't confirmed it yet, so I'm embarrassed to tell you. If it's wrong, you'll be happy for nothing."

Yuan Zhengxin shook his head and sighed: "Professor Li and Professor Ronald have completed your proof together. They both think that your proof is fine. Otherwise, they wouldn't have thanked me specifically. Qiao Yu, how can I praise you so much?
I asked you to join Professor Li's research group in order to familiarize you with the international collaborative research model and train you to improve yourself through international exchanges. But Professor Li said that you solved the problem almost single-handedly.

I don't know if you have learned anything in the research group, but it is true that you have really made your supervisor and I proud. I am of course happy to see you working so hard, but it is also sad to think about it. Qiao Yu, you are pushing yourself too hard, you should have a balance between work and rest when studying. "

Qiao Yu felt that the old man had misunderstood something...

After all, Mr. Yuan has always been known for his strict requirements on students.

Every time they parted ways, Yuan would tell him to be modest and not to be conceited. At his age, it was the right time to study hard and not to be affected by the noisy voices from the outside world.

Today was the first time that Qiao Yu heard the words "It's better to have a balance between relaxation and intensity when studying" from an old man. It was really rare.

Well, actually, he had always thought so. He had planned to go out to relax and play ball this afternoon, but he was stimulated by the rich second generation...

"Well, Grandpa, I know. To be honest, I'm actually quite relaxed. I'm not as tired as you think every day..."

"Okay, you don't have to say anything. Grandpa has been through your age and knows how hard it is for you. You have to keep up with your nutrition. Look, you didn't have a good meal at noon and ran back to write a certificate. How can this be allowed? Don't do it next time. If it really doesn't work, let Tian Yanzhen arrange a small kitchen for you. Whenever you want to eat, someone will cook for you."

Yuan Zhengxin spoke very seriously, and looked so serious that Qiao Yu felt it was a bit outrageous.

I have a separate study room at Yanbei University. If I brag about it, I will get a lot of envy and jealousy, which is still a good feeling.

But if I could get special tutoring at Yanbei University... the old man's imagination is a bit too wild.

He felt that if this matter were to leak out, he might be beaten up!
After all, this is a treatment that even big professors cannot enjoy, how could he deserve it?
Director Tian often asks his assistant to go directly to the cafeteria to get a portion of food...

"Grandpa, there's no need for that. I really don't need that. The food in Yanbei Canteen is good enough, and the hours are flexible. I can eat whenever I'm hungry. I'm so young, it's only right for me to run a few more steps. Besides, if you don't want to walk, there are still campus bicycles."

"Don't you need it?" Yuan Zhengxin asked again seriously.

Qiao Yu shook his head firmly and said, "It's really not necessary. Besides, we can't have a kitchen in the research center."

The old man thought about it, probably feeling that what Qiao Yu said was right, he nodded slowly and said: "Well, forget about this, but the place you live in is indeed too simple, it must be changed. The door and window are on the side, this design is not ventilated, it is not good to live in for a long time!"

"Forehead……"

Qiao Yu was thinking about how to decline politely, but the old man waved his hand and said, "Don't worry about it. I'll talk to Tian Yanzhen about this. When you come back from France next month, you must move! If he dares to disagree, I'll scold him for you and then take you to Huaqing. It's settled."

Qiao Yu thought about it and simply kept silent.

Anyway, this was not something he asked for.

As for the master scolding the mentor...that is only natural. Anyway, he has to endure it when Director Tian scolds him.

Yuan Zhengxin didn't wait for Qiao Yu to say anything, he just stood up and said, "Okay, I'll go back first, I have something else to do at Huaqing."

"Grandpa, I'll take you there." Qiao Yu immediately stood up as well.

"Ah."

Yuan Zhengxin did not refuse. It was his own grandson who was seeing his grandfather off, so there was no need to be polite.

……

When the old man and the young boy walked out of the room, Chen Zhuoyang, who was preparing for his defense upstairs, stood up. He just stretched and saw the old man's profile as he tilted his head and whispered to Qiao Yu. He was stunned and rubbed his eyes subconsciously.

It seems that I read it correctly...

But before he could take another look to confirm, the two had already turned the corner and disappeared in front of the window.

Mr. Yuan actually came to their place?
This world is truly amazing.

……

"As I said before, study is important to you now, and your health is also important. You should combine work and rest, and go out more often when you have time. You haven't been to those scenic spots since you came to Beijing, right? So, during Labor Day, you can take two days off, and I'll find someone to take you around Beijing..."

"Well, okay, Grandpa."

"You should also take time to exercise every day, stay up less late when you are growing up, and make sure you eat enough in the future."

"Well, don't worry. To be honest, I'm a big eater now."

"Haha, okay, next time you go to grandpa's place, I'll ask someone to cook the mutton you like."

"No, no, just the ones made in the cafeteria will do."

"Okay, my car is waiting. You can go back first."

"Well, goodbye, Grandpa Master!"

……

In this way, Qiao Yu sent Yuan Zhengxin all the way to the door, watched Yuan Lao get into the car, lowered the window, waved at him, made a gesture for him to turn around, and then turned back to the center.

On the way back to the room, Qiao Yu began to reflect.

Did he coax the old man too much? He suspected that even Yuan Lao's grandson would not be able to enjoy such treatment...

After all, even his grandfather didn't treat him so well back then.

Of course, my heart is still warm, it’s a touching feeling, and of course a little proud…

But then again, it doesn't matter who you become my grandson to.
Really, even if you are a rich second generation, so what? Can you enjoy this kind of treatment when you come to Yanbei University? Just live in a four-person room honestly!

But today I still have to thank the rich second generation...

After all, if he hadn't suddenly exploded, he would probably have chosen to go out for a walk. People's fate is just so coincidental!

With so many emotions in my heart, I returned to the small building and saw Brother Chen wandering at the door...

"Senior Brother Chen."

"Hey, Qiao Yu, you're back. I saw you going out with an old man just now. I think the old man is Mr. Yuan, right?"

"Yes, Master came here specially to see me."

It’s confirmed, I didn’t see it wrong just now!
"Hey, Qiao Yu, you are really generous. How about, when I defend my thesis after Labor Day, can you help me invite the old man to attend my graduation defense? Anyway, the old man has read my thesis." Chen Zhuoyang said shamelessly.

The doctoral dissertation defense is supposed to involve professors from outside the school, and after the defense, the doctoral student will have to take a group photo with the professors on the defense committee.

Chen Zhuoyang felt that he could brag about it for the rest of his life when he could take a photo with Director Tian and Mr. Yuan. No matter where he went in the future, he would frame that photo and hang it in his office...

Qiao Yu glanced at Chen Zhuoyang and said with a smile: "Brother Chen, this is too much! You asked me to invite you to your graduation defense? If you become a professor at a university, can you give me your first year's salary?"

Chen Zhuoyang's eyes lit up and he said, "Really? Then it's a deal! Let's not talk about salary. All my income in the first year, whether it's salary, bonus, or performance, will be yours. Just help me invite the old man to come when I defend my thesis."

This is outrageous. Qiao Yu looked at Chen Zhuoyang with a curious look on his face and asked, "Brother, please don't tell me that you are actually a rich second-generation!"

Chen Zhuoyang shook his head and replied, "I can't say I'm a second-generation rich man, but my family is not short of money, so I'm an average middle-class person. Anyway, we have a deal. You can try to invite my senior brother. Anyway, whatever my senior brother gets in the first year is yours."

After saying that, he didn't even give Qiao Yu a chance to object and just turned around and went upstairs.

Qiao Yu curled his lips. It was obvious that Senior Brother Chen, who was about to graduate, had gone completely insane and couldn't stand money anymore.

……

On the other side, Tian Yanzhen, who had just finished a meeting and walked out of the building, his cell phone rang in his pocket.

I took it out and took a look at it, and was very surprised.

Although the two had met in the Century Auditorium of Huaqing Library, Tian Yanzhen never expected that the old man would take the initiative to call him one day.

But he soon thought of Xue Song's report in the afternoon, and a smile appeared on his face.

When the call was connected, the old man's powerful voice made his eardrums vibrate.

"Tian Yanzhen, my grandson is studying in Yanbei, and you let him live in a utility room? There's not even a bathroom in the room! Don't you know how cold it is in Beijing at night? He has to go out to use the bathroom? How can you be a tutor? If you are short of housing, take the initiative to tell the child to come to Huaqing! I will arrange it for him!"

Tian Yan was really shocked.

The moment he answered the phone, he thought of many things that the old man might say to him, but he never expected that Mr. Yuan would say these words.

To be honest, the single room that Qiao Yu lives in now is no worse than that of a doctor.

Many doctoral students had to rent houses outside because of the shortage of dormitories at school. However, Qiao Yu already had his own dorm before his student status was transferred to Yanbei University...

Really, Qiao Yu’s accommodation treatment is enough to make many doctoral students envious and jealous. Tian Yan never thought that his former teacher would pick this matter to criticize him.

Then again, as far as he knew, even for doctoral students at Huaqing University, the accommodation conditions were just so-so.

The environment of Bauhinia Apartment may not be better than Qiao Yu’s accommodation conditions.

Of course, the lack of a toilet in the room is a real drawback.

But Tian Yan really understands his teacher. To be honest, hasn’t Mr. Yuan always believed that one should endure some hardships when one is young?

So he said gently: "Mr. Yuan, Qiao Yu is still young, although the temporary dormitory does have some shortcomings..."

"What do you mean by some shortcomings? I won't say anything about the small accommodation, but there is no bathroom, and the door and window are on the side. If your place is like this, I won't say anything! So, if you insist that this is no problem, I will find a decoration team to change your house into a similar layout? I will pay for it!"

Tian Yanzhen fully realized how sharp the old man could be when he was not about to start reasoning.

After thinking about it for a while, Tian Yanzhen said directly: "Okay, Mr. Yuan. You are right. Qiao Yu's current conditions are indeed a bit difficult. So, there is an office on the third floor of Qiao Yu's building, which can be vacated next month. By the way, clear out the room next to it, renovate a bathroom, and add a suite. What do you think?"

“Can ventilation be achieved from north to south?”

"can."

"Well, it needs to be renovated before he comes back from France! Use good materials and make sure there is no renovation pollution. If there is a financial shortfall on your side, Huaqing can also contribute part of it."

"No need, Mr. Yuan, don't worry, it must be the best material."

"Well, if you want to pay attention to this matter, I will go and see it."

“You are always welcome to supervise the renovation project.”

"If you can't do it, I'll take him away. Stop talking nonsense! Toot-toot-toot..."

The person on the other end hung up the phone directly, very rudely, as if it was an ultimatum.

But there was no way. Even if Tian Yanzhen wanted to say something, she no longer had the chance.

My former mentor has already hung up the phone.

Tian Yanzhen shook his head and was too lazy to greet others. After walking out of the building and getting in the car, he directly called Qiao Yu.

Based on his understanding of Mr. Yuan, he couldn't be staying well in Huaqing and suddenly want to come to Yanbei to see Qiao Yu. There must be a reason.

Otherwise, wouldn't it be better to just call Qiao Yu to Huaqing?
Soon the person on the other end answered the phone.

Qiao Yu's voice also came: "Director Tian, ​​what do you want?"

Well, this "instruction" sounds particularly heartwarming today.

"Did Mr. Yuan come to see you today?"

"Yes, Director Tian, ​​Mr. Yuan stayed with me for about twenty minutes today, asking me to study hard and make progress every day."

"Tell me, what shocking thing have you done to make Mr. Yuan come to visit you in person."

"Speaking of this, I have to thank you!"

"Thank me?"

"Yes, didn't you say in one of your lectures that we should seek the unchanging in the changing, and seek simplicity in the complex?"

"Is this... the time to talk about the principle of symmetry?"

"Yes, yes, this sentence was relayed to me by Senior Brother Chen. It was your words that inspired me, just like sunlight shining directly into my brain, and then I accidentally solved a difficult problem that Professor Li and his team were currently facing in their research.

Professor Li was not a man of honor. He didn't even thank me, but went straight to thank my master. Then my master probably thought I was doing him too much honor, so he came to encourage me and talked to me a lot. Then I sent Mr. Yuan off in the car. "

Tian Yanzhen suddenly felt very complicated.

A difficult problem may sound simple, but anyone who does math certainly knows what it means.

"What problem did you solve?"

"I helped Professor Li and his colleagues prove that on a given commutative stack, all global functions can be described by endomorphisms of the Whittaker layer, and the structure of these endomorphisms is directly related to the representation of algebraic groups."

"Are you sure there's no problem?"

"Grandmaster said that Professor Li told him that my proof was very beautiful. They completed the process and felt it was very correct! He wanted to give me a lot of thumbs up. By the way, today Grandmaster asked me to move to Huaqing, but I refused. I will be a Yanbei person all my life, right, Director Tian?"
