　　 In high math class, Yang Rui listened very carefully.

　　 Although some people can learn advanced math through self-study, it is really only some people. In fact, there are many ways to learn mathematics, but they are only suitable for very few people.

For example, the famous Mr. Hua Luogeng, his reading method is very distinctive. When he got a large mathematics book, Hua Luogeng’s method is to read the first few pages first, then close the book, close his eyes and meditate, and then turn directly to the book. Look at the answer on the last page of the script. If the answer is correct, the book is considered to have been read.

　　This kind of reading method cannot be more efficient. Hua Luogeng himself has read countless books in this way, but in reality, there are really very few people who can use this method.

　　 Yang Rui has no mathematical talent, nor does he pursue high-level mathematical skills. He just needs to reserve some mathematics.

　　In history, although there are some creatures who are very mathematics, this is not a necessary condition.

In Yang Rui’s view, although mathematics geniuses are rare, they are not uncommon on college campuses. You can find them whenever you use them. For example, ordinary geniuses like Zhao Pingchuan who don’t even major in mathematics are enough for ordinary biological experiments. Room used.

　　 However, Yang Rui's own mathematics reserve distance is not enough. Fortunately, he will not waste the opportunity to study at Peking University. No matter how busy the laboratory is, high-level math classes will always come.

Now Peking University, the focus of education is undoubtedly the undergraduate class. Almost the best professors, including the former academician Da Ben, will try their best to give lectures to the undergraduate class. This is only the elite education in the 1980s-the most open attitude , The freest thoughts, the best students, the top professors, and the most concentrated resources.

　　 This quality of education is difficult for future generations to enjoy even for doctoral students. In fact, doctoral students no longer attend classes. In most cases, doctoral students study in the process of research and work during the learning process. It is no different from lecturers and assistants in universities, but after 30 years, think again If you enjoy small classes with high-level professors in the 1980s, you can only go to Cambridge Harvard.

　　 Yang Rui is very keen on advanced mathematics courses, and he will also do exercises when he has time. In terms of progress, he is also superhuman. At the end of a class, he went to the podium to question the professor.

　　 After all, Yang Rui is a person who has studied for a while, and then there is no problem in the short-term for the freshman level of advanced mathematics.

　　 The current professors are also happy to answer, and they leave in a hurry if they don’t have classes. It’s only four or five years before the college entrance examination is resumed. Many professors have just returned to school, which is the time when the enthusiasm burst...

　　 Yang Rui stayed in the classroom for a long time, but Chen Yi and others outside were anxious, and had to hide behind the classroom to confirm Yang Rui's deeds.

　　 When Yang Rui ended the problem and went out, Chen Yi was panicked again, and ran at a short pace before catching up with him.

　　 "Mr. Yang." Chen Yi panted behind Yang Rui: "I have found out about the stamps. I have made a list. Would you like to take a look."

　　 "Walking and watching."

　　 "Wait a minute." Chen Yi flipped through his shoulder bag and handed a notebook to Yang Rui.

　　 20 sets of "Mei Lanfang" and 100 sets of "Love of Science since I was a Child"...Although they are relatively ordinary stamps, they are indeed of relatively high value. For example, a set of Mei Yanfang can sell for hundreds of dollars in the 1980s.

　　 However, there is still a big gap between the stamps and the number of such stamps and Yang Rui's expectations.

　　 He turned down casually, until he saw a few words about the full set of military mail, and then stopped.

In the philatelic industry, military postage usually refers to "Yellow Army Post", "Purple Army Post" and "Blue Army Post". The most famous of these is the Blue Army Post. The price is as high as one or two million.

　　 In Xiao Chen's notebook, the price of this set of stamps is 6000 yuan, which is more expensive than 20 sets of Mei Lanfang, but there is much room for appreciation.

　　 Of course, such a full set of military mail can be met but not sought, and it is also excellent to stay.

　　 Yang Rui closed the notebook and asked: "Are these the other party confirmed to sell?"

　　 "Of course, sure to sell."

　　 "I only want the whole product and the price is 20% off. I want all of it. If possible, I will come to the transaction." Yang Rui handed the notebook back to Xiao Chen and walked away.

　　 Xiao Chen froze for a while, and didn't know if it was good or not, so he hurried back to report.

　　 The next day, there was another round of bargaining. Yang Rui bought all of the other's full-quality stamps at a price of 85 percent, which made everyone excited.

　　 For a transaction of more than 30,000 yuan, I took out the money in one breath, and even the counter-offer was not particularly powerful. Such a local tyrant naturally makes people feel the flavor of stupid money coming quickly.

　　Furthermore, the original owner of the stamp also bought two thousand yuan of national debt to show his gratitude. For the bank director who sold the national debt and sold the heart disease, this is better than any special medicine. At the same time, he plans to introduce more stamp collectors to Yang Rui.

　　 And in school, rumors that Yang Rui earned money to buy national debts are also widespread.

　　 Since the New Year's Day party, the super-looking Yang Rui has silently received attention from the school grass. If someone else bought the national debt, at most it would be a discussion in the class or the department.

　　 Said that Yang Rui bought the national debt~www.NovelMTL.com~ Everyone doesn't care if he actually bought it or not, but the news flew out all at once.

　　 Moreover, this has become a hot topic in the next few days.

　　 On Friday, Yang Rui was simply blocked in the dormitory by the chairman of the student union.

"Join the student union." The chairman also wears a woolen coat with his hands in his pockets. He is very handsome and said: "The student union is a student organization and the link between the school and the students. I think Yang Rui, you are very suitable to join. From the Student Union..."

　　 He talked a lot about it, and then looked at Yang Rui with dark eyes, as if waiting for him to accept his head and worship.

　　 For current students, joining the Student Union is indeed an excellent choice. Because it is still a distribution system, the student union first has the advantage of good distribution. Although it may not necessarily be assigned to a good unit, when there is a choice, the student union cadres can always get a better choice.

　　 This is a direct benefit, which is completely different from the indirect benefit of the later student union.

　　 However, Yang Rui didn't pursue this at all, and said with a smile: "I am busy in the laboratory, I am afraid I won't have time in the student union, sorry."

　　Laboratory work is an extremely useful privilege, especially Professor Tang Ji's management is relatively loose, and Yang Rui raises his banner almost casually.

Your Excellency seems to have never expected that he would go out in person and be rejected. He was taken aback and smiled again. He said, "You'd better think about it again, so be it. If you have time, our students will turn around. I'll give you a call." ."
