The Magic Trading System

Zheng Hao looked in the direction that Li Yan pointed to, but saw a few men and women sitting at a table not far away. It seemed like a family gathering.

Sitting at the top of the table was an old man with gray hair, ruddy complexion and vigorous spirit.

Does the old man look at least sixty years old? With bright eyes and a smile on his face, he was talking to an old lady next to him.

Zheng Haoxin said, is this old man Professor Qian Kaiyuan?

It doesn't look like it's hard to deal with.

"Zheng Hao, do you see it? Professor Qian is the old man who sits at the top with pale hair and a good face and sharp eyes Li Yan said in a low voice.

"It looks good." Zheng Hao smiles.

"Yes, the old man is very kind and has no airs, but he is very principled. If the students offend him and can't give a reasonable explanation, the possibility of failing in the course is almost 100%." Li Yan said.

"Oh, Li Yan, do you think I'll go and say hello to Professor Qian?" Zheng Hao blinked.

"It's OK to say hello. Let's go there together later. We'll have a toast with him and say a few compliments to make a good impression on him first. Then, you can visit him at his home. I think it will be much better." Li Yan said.

"You're right." Zheng Hao nodded.

In a short time, their food was on the table.

In order to facilitate the toast, Zheng Hao specially ordered a bottle of the best red wine in the shop.

Zheng Hao saw that Qian Kaiyuan had already begun to eat, so he said to Li Yan, "shall we go now?"

Li Yan said, "good."

Zheng Hao opened the bottle of red wine. He wanted to pour some for Li Yan first. Li Yan shook her head and said no, she only drank boiled water. Zheng Hao shrugged and had to pour half a cup into his tall cup.

They went over with cups.

Li Yan and Qian Kaiyuan have dealt with each other. Naturally, she takes the lead.

"Hello, Miss Qian! Your family is eating here, too! " Li Yan with a faint smile bows to Qian Kaiyuan.

Zheng Hao was also smiling and nodded to Qian Kaiyuan.

Zheng Haoxin said that Li Yan didn't have any social skills.

"Oh! It's Li Yan! Hello, hello! I haven't seen you for a long time. How's it going? " Qian Kaiyuan saw Li Yan and stood up happily.

"I'm ok. Mr. Qian is as elegant and handsome as before." Li Yan exchanged greetings with Qian Kaiyuan with a smile.

Qian Kaiyuan looks at Zheng Hao.

"Who is this? It looks a little familiar. " Qian Kaiyuan nodded to Zheng Hao with a smile.

As soon as Zheng Hao wanted to introduce himself, Li Yan said, "Mr. Qian, this is Zheng Hao. He got full marks in the college entrance examination this year. He is also the only student with full marks since the implementation of the college entrance examination system. He was admitted to the Chemistry Department of Tsinghua University. No, the freshmen are about to start school. He came to report."

When Qian Kaiyuan heard Li Yan's introduction, he frowned first.

The old man looked at Zheng Hao and said, "no wonder I'm familiar with you. I've read nearly 100 reports about you recently. They've blown you too high. It's the first day that they've blown you into a nobody before and after! If you don't learn it, you can learn the most difficult parts of higher mathematics such as differential geometry and algebraic geometry by self-study. To be honest, at the beginning, my expectation for you was quite high! But then my opinion of you changed. Do you know why? "

Zheng Hao said respectfully, "I don't know. Please ask Mr. Qian for advice."

"Ha ha! How dare I teach you? You said, as a student, what is the most urgent thing? Shouldn't it be learning? And you? What are you doing? You even ask the school to give you complete freedom. When you come to Tsinghua University, if you want to come to the school, just turn around. If you don't want to come, just don't come. What do you think of the school as? Is it a gilded place? What knowledge can you learn in this way? What makes me especially dissatisfied is that the leaders of your chemistry department take you too seriously and they are too accommodating to you! In order to make you not listen to my class, director Chu called me personally to explain the situation. I hope I can accommodate you. Zheng Hao, do you know how I responded to director Chu? I told him, I said, as long as Zheng Hao is late for my class even once, I will let him fail! " Qian Kaiyuan said very sternly.

Zheng Hao rubbed his nose.

He said to himself, the teacher Qian seems to have a big prejudice against himself.

"Mr. Qian, you are a responsible teacher. I must praise you. However, I think that in the matter of educating students, we should teach students according to their own characteristics rather than adhering to rigid principles. " Zheng Hao posture more and more modest, said.

He was thinking about how to make the old man change his mind.

A little thought, Zheng Hao knows that there is no other way, he can only use strength to conquer the old man."Oh! You came to educate me? Let's argue. I'll tell you why I must adhere to my principles and ask students to come to my class! That's because I think I can make students learn mathematics faster and better, and my teaching can be more efficient than students' self-study! Although college students focus on self-study, they also need to cultivate self-study ability, but you also need teachers with rich experience and scientific research theory to guide you in the direction of learning, so that you can get a glimpse of science faster! " Qian Kaiyuan said.

"Miss Qian, if I say that I have learned the course you want to teach well? Do I still need to sit in class and listen to you? " Zheng Hao also asked.

"Do you think you've learned all the math I taught you?" Qian Kaiyuan had an incredible look on his face.

"Yes, I think that I have learned mathematics well, at least enough for my subsequent research work." Zheng Hao nodded.

"Don't you understand the reason of boundless learning? Mathematics is a broad and profound subject. Even the most excellent mathematicians in the world dare not claim to have learned mathematics well. The more they learn, the more they realize their own shortcomings and deficiencies. It is often you who only learn a little bit that are so proud, and even claim that you have completely mastered mathematics. Zheng Hao, to be honest, your words will make you really happy People who know mathematics laugh at you Qian Kaiyuan taught Zheng Hao seriously.

"Of course, I also know that it is impossible to master mathematics completely. I mean, my knowledge of mathematics is enough for me to use in the field of chemistry." Zheng Hao said.

"Well, do you still insist on not going to my class?" Qian Kaiyuan looks at Zheng Hao and asks.
