"Yes, let's see if my calculation is correct. The calculation of this problem is very heavy. Many of my steps are mental calculation, and there is no formula at all." Zheng Hao said to Qian Kaiyuan.

"Well, let me see!"

Qian Kaiyuan began to take Zheng Hao's steps seriously.

The more he looked, the more frightened he was, and the more incredible he felt.

Zheng Hao's problem really saves a lot of steps that need a lot of calculation, but there are no less important steps to solve the problem. The steps to solve the problem are clear.

Looking at the complete solution, Qian Kaiyuan was silent.

He said, this child is really talented in mathematics.

Before he began to go to university, he had mastered so skillfully the field of mathematics, which is so difficult in algebra and geometry. In time, if he had been trained seriously, what would he have achieved in mathematics?

It's hard to imagine.

Qian Kaiyuan was excited.

It's not difficult to find a student with good mathematics in Tsinghua University. However, there are few talents who want to find a talent in mathematics and expand their academic research in mathematics.

"Old man, is he right? Why are you so stupid? " Qian Kaiyuan's wife saw that his wife was in a daze after reading the question, so she couldn't help asking him.

Qian Kaiyuan found that he seemed to be silent for a long time. He quickly said with a smile: "the answer is very good. It's not easy to finish this problem in such a short time! As you said just now, this problem is really too much computation. When my doctoral students do this problem, it takes the shortest student more than an hour to finish it. "

Li Yan is a happy, busy to Zheng Hao said: "teacher Qian said so, but in praise of you, I had three lessons of teacher Qian, but he did not praise it once."

Zheng Hao nodded to Li Yan with a smile. Then he said to Qian Kaiyuan, "Mr. Qian, thank you for your affirmation."

At this time, Qian Kaiyuan said, "it's a pity that you study in the Department of chemistry! I think you should go to the math department. Your talent in mathematics is really amazing. If you study in our mathematics department, I can guarantee that you will grow into a first-class mathematician in China or even in the world in the future! "

Zheng Haoxin said, why do I study mathematics? Mathematics is only a basic subject, it can not bring huge economic benefits, it can only give other subjects a hand.

He thought so in his heart and said, "chemistry is what I am most interested in, Mr. Qian. I think learning chemistry can bring me more sense of achievement."

Qian Kaiyuan sighed, shook his head and nodded: "you're right. I can understand that. I'm just sorry that such a good mathematical seedling can't contribute to the development of mathematics. Well, if you can learn mathematics to the present level, you really don't need to come to my class again. You just need to come to take the exam at the end of the semester. I will give you a high score. "

Zheng Hao listened, in the heart a joy, his heart said, good! Finally, I don't have to worry about it.

"Thank you, Miss Qian! Here's to you Zheng Hao raised his glass to Qian Kaiyuan.

Qian Kaiyuan picked up his glass and touched Zheng Hao.

Then, Zheng Hao said a few polite words, and then he left and went back to his table to eat.

"Zheng Hao, you must be the first student who can get a pardon from teacher Qian and get credit without taking his class." Li Yan said with admiration.

"I'm lucky, to say the least." Zheng Hao picked up a piece of mutton roll from the small pot in front of him and said.

"It has nothing to do with luck, or you are more powerful! There are so few freshmen like you. I think you will become a famous person in Tsinghua soon. " Li Yan said.

They eat as they talk. They eat fast.

The main reason is that they are all fast-paced athletes, and they will not be able to eat for three or four hours like others.

After dinner, they said hello to Qian Kaiyuan, and then they left to check out.

At the time of checking out, Zheng Haoshun also settled the account at the table of Qian Kaiyuan, which is also a kind gesture to Qian Kaiyuan.

Coming out of jingfuhua, Zheng Hao took a look at Li Yan and asked, "Xuejie, where are you going? I'll see you off. "

Li Yan said, "I'll go to the library and read some more books."

Zheng Haoxin said, this girl is really a learning maniac. Can't she relax?

"Well, I'll take you to the library." Zheng Hao said.

"No, if you want to do your own business, do it. I'll do it myself." Li Yan shook her head.

"Sister, don't refuse. Anyway, I'm fine. I'll just walk and eat. In addition, I'll go to school to pick up my car."

Zheng Hao said.

"All right." Li Yan agreed.

They walked into the school side by side.As soon as they got to the gate, a black Maserati "swish" came quickly, and "creak" almost wiped Zheng Hao and Li Yan's bodies and stopped.

Zheng Hao frowned.

He said, "how do you drive this special car?"?

Maserati's car window opened, and a greasy faced man showed his head to Li Yan and said, "Li Yan, you are very free and easy today. You have a lively chat with the handsome guy!"

Zheng Hao a listen, heart said, is there a story between this man and Li Yan?

He did not speak for the time being, listening to Li Yan's response.

"You Yang, are you a little too lenient? I'll have dinner with my friends and have a chat, so what? This is my freedom! You have no right to interfere! " Li Yan frowned and said in a cold voice.

"Ha ha! You think I'm too lenient? You are my fiancee. I care more about you. Is that too much? If I don't care about you and allow you to associate with other wild men, what will you do if you give me a green hat? Li Yan, I think we need to have a good talk. Please get in my car, OK The greasy faced man said with a laugh.

Zheng Hao was surprised, he said, this product is Li Yan's fiance?

A look at the relationship between the two people is not very normal!

If they are girlfriends and girlfriends, shouldn't their relationship be so tense? Li Yan didn't have a good look at him at all.

"It's disgusting that you should say such a thing to me! I won't get in your car, and I won't talk to you about anything. Please leave Li Yan said angrily.

You Yang opened the door and got out of the car. He pulled out a cigarette, put it in his mouth, lit the fire, took a hard puff and sneered: "what's up? Do you want to repent? "

Li Yan's eyes were red. She bit her lips and was silent for a moment. She said with great difficulty, "I will follow the agreement and marry you, but it won't be now!"
