Chapter 220 Returning to China

Looking at the four students who were tangled in front of him, Xu Chuan smiled and said, "You don't have to give me the answer now. You can think more."

"Whether you follow me to China or stay at Princeton, I have no objection and am happy to accept it."

"Go ahead, go back and think about it."

He did not let the four of them make a choice now. The resignation of the supervisor during the PhD program was indeed a big deal for the students, especially for a supervisor like him who needed to change countries. Not everyone could accept leaving with the supervisor.

After sending away several students, Xu Chuan thought about who would go back with him.

Among these four students, the most likely one is Gu Bing.

Of course, Gu Bing may not return to China with him, but the possibility is greater than that of the other three.

He didn't really care about this.

If you can follow him, he will be happy; if you don't follow him, he will just make arrangements.

The last two days of the report meeting passed quickly.

On August 9, under the arrangement of the organizer Brazil, and with a cultural performance full of unique culture, the nine-day International Congress of Mathematicians finally came to an end.

It is worth mentioning that nine days after the report meeting, the Brazilian police still failed to recover Professor Coucher’s mobile phone and medal.

Finally, at the closing ceremony, the International Mathematical Union held a special awards ceremony and re-awarded Professor Kaucher Birkar a medal, which left no regrets.

"The security situation in Rio de Janeiro is really bad. A thief sneaked in at the International Mathematics Conference and stole the Fields Medal. This has never happened at any exchange meeting before."

At the closing award ceremony, sitting next to Xu Chuan, Fefferman sighed and said.

In terms of dynamical system mathematics, South America is very strong, and can even be said to be at the forefront of the world. There are also many famous mathematicians who have come from here.

For example, top mathematicians such as Jacob Paris, Artur Avila, and Da Costa are all.

This is one of the reasons why this mathematics conference was held in Rio de Janeiro.

Although the International Union of Mathematicians was also concerned about the security situation in Rio de Janeiro, it did not expect it to be so serious.

Unexpectedly, the gold medal of the Fields Medal winner was stolen on the first day.

The attitude of the Brazilian police is such that even dogs will shake their heads after looking at it.

After the staff of the International Mathematical Union called the police, the Brazilian police only arranged for one police officer to come over to understand the situation and made a simple registration. They did not even call for surveillance, and they seemed completely unwilling to handle the case.

Such a rotten attitude made many scholars participating in the conference completely disappointed with Brazil.

It is estimated that for a long time in the future, mathematicians and even scholars in other fields will not vote to hold conferences here.

Xu Chuan smiled and said: "The security is indeed terrible, but for Professor Coucher, this may be memorable. After all, he is the first person in history to win the Fields Medal twice."

"Of course, this will also remind him to take care of his belongings when going out in the future."

Fefferman was stunned for a moment, then smiled and said: "You are right. Winning the Fields Medal twice is definitely worth remembering. Maybe Professor Coucher should treat us to a feast?"

After a pause, he continued: "How have you considered the immigration matter?"

Xu Chuan thought for a while and said, "I need to go back first, and we'll talk about it then."

Fefferman: "I still hope to continue to cooperate with you. The NS equation is a very good research direction. Even if we cannot prove it, we can get a lot from it."

Xu Chuan shrugged and said: "Cooperation has nothing to do with anything else. Now that the Internet and transportation are so developed, we can do it even from the ends of the world."

"That's true." Fefferman nodded and continued: "It's just that there are some differences between communicating in person and over the Internet."

"Besides, I feel like you actually already have the answer in your mind."

Hearing this, Xu Chuan smiled and said, "The day I make up my mind, I will definitely call you and tell you."

Fefferman: "I'll wait."

After the International Mathematics Conference ended, Xu Chuan was also preparing to pack up and return to China.

After staying abroad for three years, it would be a lie to say that I miss home.

"Professor, are you still in the hotel?"

In the room, Xu Chuan was packing his things when his cell phone rang on the table. The call was answered and it was his student Gu Bing calling. It seemed that he had made a choice.

"Well, we're still in the hotel now." Xu Chuan responded.

"Okay, I'll be right over. Professor, please wait for me." Gu Bing said and then hung up the phone.

Xu Chuan didn't pay attention and continued to pack his luggage.

After a while, the doorbell rang.

Opening the door, Gu Bing walked in from inside.

"Professor, will you work at the university after you return, or will you go somewhere else?"

Xu Chuan: “I should be a professor at NTU.”

Hearing this, Gu Bing nodded and said, "In this case, can I go back with you?"

Xu Chuan stopped his movements and asked: "Have you considered it? In fact, continuing to study with Professor Deligne at Princeton is also a very good choice, and with a Princeton diploma, it will be easier to find a job when you return to China in the future. "

Gu Bing smiled and said, "It's almost the same. If it weren't for you, I wouldn't be able to get into Princeton. I applied to Princeton three times, but no one chose me."

After a pause, he continued, "What's more, you are a Fields Medal winner. Following you, I can have a good life in China."

Before Gu Bing finished speaking, the doorbell in the room rang again.

Xu Chuan walked over and opened the door. The person standing outside the door surprised him.

"Amelia, why are you here?" Looking at the student standing at the door, Xu Chuan asked curiously.

At the door, Amelia curved her crescent moon and said with a smile: "Of course I'm looking for you, the instructor. Is there anyone else here?"

"Uh" Xu Chuan was stunned for a moment, then smiled and said: "Come in first."

"Brother Gu, you are here too."

Walking into the room and looking at Gu Bing, Amelia greeted him and then asked curiously: "Brother Gu, are you going back to China with the instructor?"

"Me too?"

Gu Bing looked at the youngest sister in surprise, paused for a moment, and then said: "Do you also want to go to China with the instructor?"

Amelia nodded and said with a smile: "I am very interested in China. I heard that there are many delicious foods and giant pandas there. I will just go there to study abroad."

Gu Bing looked at Amelia in silence, not knowing what to say.

It was reasonable for him to go back with Xu Chuan, after all, China was his home.

It was a bit puzzling that Amelia followed him.

Not only is her father a professor at Princeton, Xu Chuan also arranged Edward Witten as his subsequent mentor. Plus, Princeton is obviously better than Nanjing University. I don't understand why she chose to go to Nanjing University instead of staying in Princeton.

"You want to go to China with me?" Xu Chuan just closed the door and walked over. After hearing Amelia's words, he almost tripped and fell to the ground.

"Of course!" Amelia nodded.

Xu Chuan's mouth twitched, and he said, "Don't make a fuss. Your father is in Princeton, and I have already made an agreement with Witten. Why are you going to China with me?"

"I'm not making a fuss." Amelia replied seriously, "I have already thought about it, and my father has agreed."

Xu Chuan's mouth twitched again, and he said helplessly, "No, why are you going to China with me? Princeton is great, it suits you better than China."

Amelia waved her hand and said, "It doesn't matter whether it's suitable or not. What's important is to learn more. I think it's more promising to follow you than to follow Professor Witten."

After a pause, she continued, "Besides, I can speak Chinese."

As she spoke, she said in Chinese, "I heard that there are many delicious foods in China. I want to eat all over China in the next few years!"

When Amelia spoke, Xu Chuan and Gu Bing were stunned.

Good guy, this is still real Mandarin. Although it is not so standard, it is intermittent and has no rules, but it is no problem to use it for communication in China.

"When did you learn Chinese?" Xu Chuan asked in surprise. He had taught this student for several months, but he had never heard that she could speak Chinese.

When I was at IPHO before, I never saw Amelia speak Chinese.

"I started learning more than three or four months ago. I watched some teaching videos." Amelia smiled and said, "By the way, there is a website called bilibili in China. I watched a lot of videos on it. Chinese is really interesting. One word can express many meanings."

"For example, when I watched a quarrel video, many of the meanings in it were not meanings, but they were also meanings, and there were also many meaningless ones. So is it interesting or not?"

Amelia opened her blue eyes and looked at Xu Chuan with interest: "I still haven't figured out what the meaning of the video is. Chinese is really interesting. Maybe I should go to China to study and figure it out."

For a moment, Xu Chuan didn't know what to say.

If you can understand what the meaning is, it would be too amazing.

It only takes three or four months to master a foreign language, especially Chinese, which is extremely difficult. Amelia is so talented that she can master dozens of languages ​​if she is given time.

This is probably a quantum computer core brain, right?

"You want to go to China with me just for food and learning Chinese?" Xu Chuan suddenly asked curiously.

Amelia nodded, her eyes bright, and replied with a smile: "Of course, but food and Chinese are just one of the goals. In the past few months, I have learned a lot from you. Whether it is mathematics or physics, you can perfectly answer my questions."

After a pause, she looked at Xu Chuan and continued: "And I always feel that you are better than Professor Witten."

Xu Chuan sighed: "I think you should think about it carefully. This is not a trivial matter."

In the end, Xu Chuan still couldn't beat Amelia, just like when the other party pestered to be his student.

Four students, Amelia and Gu Bing chose to go to China with him to continue studying, while Shashi Perez and Roger Dean chose to stay in Princeton.

Everyone has their own ambitions, and Xu Chuan has no objection.

Before leaving, the four students sent him to the airport and said goodbye to him.

"Roger, Shashi, even if I leave, remember to study hard." At Rio de Janeiro International Airport, Xu Chuan patted the shoulders of the two students and said goodbye with a smile.

"I will work hard, mentor." Roger Dean nodded vigorously. Although Xu Chuan only taught them for a few months, a teacher is a teacher for life.

What's more, with their original conditions, it is highly likely that they would not be able to apply for Princeton. It was Xu Chuan who gave them this opportunity. Not only did they enter Princeton, the holy land of mathematics, but they also had two Fields Medal winners as mentors.

"Roger and I will remember to visit you, professor." On the side, Shashi Perez, who was usually not serious, also calmed down.

"I hope to see you standing on the stage and giving a report in St. Petersburg in four years."

Xu Chuan smiled and waved, and after saying goodbye to the four people, he turned around and walked into the terminal hall.

Not long after, a silver-white passenger plane slowly slid towards the runway and finally disappeared in the sky.

After a transfer, from Brazil to Europe, and then to Beijing, more than ten hours of travel passed. Xu Chuan looked at the prosperous city under his feet, and his heart was filled with a little ripple.

From the past life to this life, to this day, those memories are still deeply imprinted in his mind, and will not be erased by time.

The plane slowly descended and stopped at the end of the runway.

Xu Chuan dragged his luggage and walked towards the exit with other passengers.

In the reception hall, a group of people in suits and leather shoes stood, looking at him with a smile on their faces.

Seeing this group of people, Xu Chuan was slightly stunned.

Before returning to China, he knew that he would be picked up at the airport, but he didn't expect there would be so many.

At a rough glance, there were probably thirty or forty people in the reception hall. And there were many people in the crowd that he was quite familiar with.

Looking at Xu Chuan in the hall, Academician Pan Deming, who was standing in front of the group of people who were picking up the plane, walked over quickly with a smile on his face, leading others to move forward together.

"Professor Xu, welcome back." Academician Pan Deming extended his right hand enthusiastically with a bright smile on his face.

"Academician Pan." Xu Chuan released the suitcase and shook hands with the old man in front of him with a smile.

On the side, in the crowd of people welcoming him, another old man who seemed to be of high status came over with a smile.

"Professor Xu, welcome home." The old man walked up to Xu Chuan and extended his hands enthusiastically.

Although Xu Chuan had never seen him, he guessed that this person's status was not low, because Mu Liangcai, who had flown to Brazil before, was standing on the side, and Mu Liangcai was a deputy-level leader of the Organization Department, and could only stand on the side to accompany him.

"Professor Xu, this is Qin Anguo, director of the Science and Technology Department." Pan Deming introduced with a smile on the side.

Hearing this, Xu Chuan suddenly understood that the top leader of the Science and Technology Department, this status needs no further explanation. He smiled and stretched out his hand, shook his hand and said: "Hello, Director Qin."

The reason why he flew to Beijing today, instead of Jinling or Modu, was because this person asked Mu Liangcai to bring a message.

Qin Anguo waved his hand with a friendly smile on his face: "Don't be so polite, we are all family, if you don't mind, just call me Uncle Qin."

Xu Chuan smiled and glanced at Mu Liangcai next to him. The two routines are the same.

Mu Liangcai didn't pay attention to Xu Chuan's eyes, and said with a smile: "Professor Xu, you must be tired after sitting on the plane for so long. Let's get in the car and go to the hotel first, and then have a good chat and welcome you."
