From top stream to scholar

"Professor." Yu Wanzhou sat on the chair, "You look for me."

"When are you going back to Princeton?"

"Hmm... probably in March." Yu Wanzhou thought for a while, "Professor, do you need anything for me?"

"Yes." Professor Chen Yuan nodded, "How is your research on NP-complete problems?"

"It's not bad, the progress is relatively smooth, but I haven't studied it for the past few days, and I will continue to study this problem immediately." Yu Wanzhou thought for a while, "Professor, what is this?"

"It's nothing serious, I just want to ask you what you did at Princeton University." Professor Chen Yuan stared at Yu Wanzhou with a smile, "I heard that your chemistry paper has been published on jacs, right? ?”

"Uh, I just saw the email yesterday, and it is true that jacs has already replied to me, that it has passed the review and published the paper." Yu Wanzhou scratched her head and said, "I actually didn't come up with this thing because NP completely guessed it. , so I went to do a chemical experiment, I didn't expect that a blind cat met a dead mouse, and it was done."

"I plan to continue to stay in the mathematics department in the future, right?"

"Yes." Yu Wanzhou nodded with certainty. He definitely wants to stay in the Department of Mathematics, otherwise, where else can he go.

"I read your paper, and I think you should have some unique ideas in material chemistry."

"Um, it's just a small idea." Yu Wanzhou smiled, "The most important thing now is to solve the NP-complete problem."

"How long do you plan to stay at Princeton University? I heard from Lin Wei that you can complete NP-complete problems as early as next year, and you plan to apply for a doctoral degree after completion?"

"I have this plan. If it can be completed next year, it is best to be able to apply for graduation." Yu Wanzhou said in a deep voice, "Then I may stay in Princeton for a few more years, which is quite good for my academics. Helpful, especially in theoretical physics."

Professor Chen Yuan looked at Yu Wanzhou, nodded slightly and said, "It's good to stay there for a few more years, but if, I mean, if you want to go back to China, where are you going to go?"

"It should be back to Yucheng." Yu Wanzhou thought for a while, "But there are not many research institutes in Yucheng, which is more troublesome."

"You mean, we should set up a mathematics institute?"

"Comprehensive research institute is also possible." Yu Wanzhou said with a smile, "However, it should be difficult to get approved."

"It's really difficult. Even if you are a Fields Medal winner, your suggestions may not be adopted. Unless...you can win the Nobel Prize." Professor Chen Yuan said with a smile, "If only the Institute of Mathematics , based on your academic reputation for winning the Fields Medal, you should be able to approve it."

"Oh, but what I want to study is not just mathematics." Yu Wanzhou scratched her head, "Forget it, let's take a step at a time."

Yu Wanzhou smiled wryly, "I may enter the Institute for Advanced Study in Princeton to stay for a while, but I should be very busy. I think Brother Lin Wei is always busy."

"After all, that's where Einstein stayed." Professor Chen Yuan also agreed with Yu Wanzhou's views, but he also made some comments, "However, Wanzhou, since you are going back to China, you must remember to meet you and leave. Accept. It’s not that I want conspiracy theory, I always feel that you have been there for a long time. You are not an American citizen, I guess it will be difficult for them not to attack you..."

"Especially the field of your research is too broad. You are studying mathematics, physics, and chemistry. I think they don't want Mr. Qian to appear in Huaguo."

Regarding this point, even if Professor Chen Yuan didn't tell him, Yu Wanzhou would pay attention to it.

What America looks like, he knows very well.No, there are really some people in this world who think that America is a lighthouse, right?

Yu Wanzhou talked with the professor for a long time. Xie Qing was wandering alone in Yucheng University, but was kicked out by the professor. He didn't know what he said to Senior Brother Yu in the office.

"What's the matter? Junior brother is here alone?" Yu Wanzhou walked up to Xie Qing with a smile, and said to him, "The professor asked you to go back to do the project. If you don't go back, the professor should be angry. "

"Hey." Xie Qing thanked Yu Wanzhou and hurried back.

Seeing his appearance, Yu Wanzhou shook her head.

When she got home, Yu Wanzhou was about to enter her room to continue working when she saw her sister-in-law packing something.

Yu Wanzhou asked curiously, "Sister-in-law, what's the matter? Did my brother offend you?"

"What are you thinking?" Wu Tong laughed, "Your sister and brother-in-law are going to your brother-in-law's place for the Chinese New Year, am I packing something for them?"

"Oh." Yu Wanzhou nodded and didn't take it seriously, "What about my parents? Did you come to Yucheng for the Chinese New Year this year?"

"Follow your sister and brother-in-law to go there too, and your brother-in-law's parents invited you to go. They say it's just to relax, don't think too much." Yu Wanzhou said again, "So we're celebrating the holiday this year, and the rest My brother, sister-in-law, and nephew live together?"

"It should be you alone. Doesn't the whole family have to go there?" Wu Tong said with a smile, "You are alone at home, take good care of the house."

"No way." Yu Wanzhou was taken aback, "I'm alone?"

"Okay." Yu Wanshen came out and said, "Don't tease Xiaozhou, you should clean up Xiaozhou too. We are not going to Jiang's house for the New Year. We are traveling for the New Year. We are going to Qiong Province, and we just rented a house there for a short period of time. Yes Brother Song entrusted you with the rent, and it happened that Jiang Yi said that he wanted to take his parents to Qiong Province, so don’t we also want to take our parents to Qiong Province to relax? We hit it off and decided to celebrate the New Year there.”

"Uh..." So that's what happened.Yu Wanzhou nodded to show that she knew, "Then I'll go clean up first, it's quite hot over there." After Yu Wanzhou finished speaking, she turned and went back to the room to pack up.Fortunately, he has received half of them now, and he hardly needs to find any documents and materials on arXiv. "

"By the way." Yu Wanzhou thought of the most important question, "Did my parents agree?"

"It's not going abroad, can you disagree? Isn't it just that they want to go out to relax? That's why they dragged your senior brother to rent a house there. It's quite wide, it's a villa, your senior brother said it's cheap, so Just rent it out."

Yu Wanzhou thought for a while, "Could it be my senior brother's villa."

"Although he's not from Qiong province, his family is quite rich. Good guy, maybe it's his family's villa." Yu Wanzhou complained, "How much."

"You don't care, you shouldn't pay the money, it's fine for me, your brother-in-law, and Jiang Yi to pay."

"Okay." Yu Wanzhou didn't have any objection to this, packed her luggage, took her unfinished NP complete problem, and the family headed to Qiong Province.When they came to Qiong Province, Song Hui specially drove a car that could accommodate many people to pick them up.

Yu Wanzhou greeted Song Hui and said, "Senior Brother Song."

Song Hui turned to Yu Wanzhou and said, "Damn! Do you still have the face to see me?"

Then he said to Yu Wanzhou's parents with a professional smile, "Hello, uncle and aunt. My name is Song Hui, and I am Yu Wanzhou's senior brother."

"Hello."

"I told you on the phone, maybe you can't find it, so I'll pick you up."

"Thank you, Teacher Song."

"It's okay." Song Hui hurriedly stopped, Yu Wanzhou winked at Song Hui, and said to Yu Wanshen, "Brother, I'm Associate Professor Song now."

"Huh?" Yu Wan was stunned for a moment, "Ms. Song is already an associate professor?"

"I just graduated with a Ph.D." Song Hui said shyly, "After returning to Yucheng University after the summer vacation, I can be an associate professor."

"That's amazing, Associate Professor Song." Yu Wanzhou never beat around the bush when talking with people he knew, not to mention spending a lot of time with Song Hui.For Yu Wanzhou, Song Hui is his senior brother, the kind who is close to him.

"That's enough, you scare me enough." Song Hui glared at Yu Wanzhou. After getting into the car, Jiang Xi asked, "Mr. Song, did Xiaozhou cause you trouble again?"

"It's not to cause trouble. This guy is making trouble again. It can't scare me."

"What? Xiaozhou, what are you doing at Princeton?" Yu Wanrong said, "Why did you get Teacher Song?"

"Hey, you don't know. This guy, some time ago, suddenly published a chemistry paper. The popularity of our mathematics circle in Huaguo was so great that the professor's phone kept ringing that day, and he thought this guy was just playing around in mathematics." I'm tired, and I'm going to the Chemistry Department." Song Hui took a breath and continued, "I was also anxious at the time, and when I saw that paper, I went to the professor directly, but the professor was also frightened."

Jiang Xi tapped Yu Wanzhou's head lightly, "I won't tell you anymore, I tell you not to make troubles, just make troubles."

"Don't tell me, I actually saw this paper on jacs a few days ago." Song Hui screamed and said, "Junior Brother, can you spare me, and accept the supernatural powers. Do you know how many people there are in Huaguo?" If you want to submit a paper on jacs, you can't pass it. The group of people in the chemistry department are already eyeing you, threatening to beat you with a sack every time they see you. Please do me a favor, hurry up and study your mathematics, don't mess around It's over."

"Don't tell me, the more I look at Xiao Zhou, the more I think he deserves a beating." Jiang Xi said with a smile, and the whole car was filled with a cheerful atmosphere.

When they arrived at the villa, Yu Wanzhou got out of the car and looked around, and it was quite good.This environment is also quite elegant, and there is no one living nearby, and it seems to be very quiet.There was even a big swimming pool, Yu Wanshen and the others went in first, while Yu Wanzhou and Song Hui stood outside the door.

"Brother, I didn't realize that your family is so rich." Yu Wanzhou said in amazement, "You are so rich and yet so stingy, is it plausible?"

"Hehe." Song Hui sneered, "I make my own money and spend it on my own. If I don't work hard, I will go home and inherit billions of dollars. You don't understand this kind of pain."

"Give me a chance, let me understand your heartache, okay?"

"Get out!" Song Hui waved his hand, "Go ahead and play, I'll go first, enjoy your wonderful vacation here."

Song Hui walked to the car, and said as if remembering something, "This villa has internet, so it's very convenient for you to check information."

"Thank you!" Yu Wanzhou waved Song Hui and made a goodbye gesture.
