The old man walked away with anger, and by the time Chen Qiaoshan chased him out, the old man had already arrived downstairs and was pushing an old bicycle and preparing to leave.

After his retirement, except for some official activities and off-campus academic exchanges, Professor Yan usually went around the Economic Research Center at home, and rarely even came to the Scholastic Academy.

The old man has a special car, and the treatment is similar to that of Li shares, but he usually counts on the old permanent, and there is a bamboo children's chair tied to the back seat of the car, which is Yan Yan's special seat.

The little girl is the top of the Yan family, she is not very old, but she is really not light, the old man has reached the age of ancient times, and it is a little difficult to hold, and occasionally he will take the little girl to walk around the campus, which is a rare family.

Seeing Chen Qiaoshan come out, Professor Yan's face was a little pale, but he didn't pay attention to it, and rode away, looking at the direction should have gone to the Economic Research Center, Qiao Shan had no choice but to follow.

The mentor-apprentice duo of one old and one young was not conspicuous on campus, and it was not until he entered the office that Professor Yan sat behind his desk and asked, "I heard that you read books when you are idle at home?"

Chen Qiaoshan was stunned for a moment, and then said with a wry smile: "Yes, old man, it is said that the fortress was breached from the inside, but I didn't expect someone to report to you." ”

The most familiar with Chen Qiaoshan's situation is Xiao Wu except Yan Xiaoqin, the former is doing the final debugging preparations for the launch of the website, he is busier than him, and the one who can chat with the old man is Xiao Wu.

Professor Yan said: "Xiao Wu is much more intimate than you, at least he knows to come and talk to us every weekend, you are good, you can't see a figure in your spare time, and you don't know what you are busy with." ”

I don't know what the old man thinks, Chen Qiaoshan is really stupid, this should be dissatisfied with his attitude towards studying, this is also a helpless thing, he has so many investment projects in his hands, although he doesn't have to stare at it personally, but he doesn't have much time left, how can he be at ease with academics.

Just thinking about how to deal with it, Professor Yan didn't pursue it further, but asked, "Tell me, what books are you usually reading?"

"Teacher, I've been learning about regression analysis lately. ”

"Oh?" Hearing this answer, Professor Yan's face changed a little better.

Regression analysis is a predictive modeling technique, which is a quantitative study of the economy by mathematical statistical methods, and studies the potential relationship between dependent and independent variables, which belongs to the category of econometrics and is an extremely important economic tool.

So far, undergraduate education, including Guanghua and Scholasticism, has not included econometrics in the teaching plan, and only at the graduate level will research in subdivided fields be conducted.

Although this disciple seems to have no intention of learning, he is still conscious, at least the progress of learning is not slow, Professor Yan is also relieved at this time, and there is finally room for salvation, "In this way, you just need to come to me once a week in Yanjing and talk to me about the progress of learning, what do you think?"

Talking about progress is fake, I'm afraid that the teaching exam is real, although Chen Qiaoshan knew the old man's intentions, he couldn't refuse, so he had to accept it.

Seeing that the disciple should be down, Professor Yan didn't say anything more, got up and rummaged through the bookshelf behind him for a while, and finally took out a long paper tube from the top layer.

Chen Qiaoshan looked at it, it should have been some years, and there were layers of old newspapers wrapped outside, and he didn't know what was in it.

Professor Yan checked it quite solemnly, and saw that the packaging was still in good condition, so he sighed, put the things on the desk and said: "This is a painting given by my economist when I stayed at Peking University to teach, and now I have only one student like you left in my door, so I will transfer it to you today." ”

Chen Qiaoshan was overjoyed, but he still excused himself and said, "Old man, this is not appropriate, or you should leave it to Brother Yan." ”

Professor Yan glared at him when he heard this, and said, "Don't think about it, since it's given to you, you can continue, okay, don't waste time with me, take your things and go." ”

Chen Qiaoshan happily picked up the pair of words, feeling light and fluttering, and it didn't have much weight, so he put things away, and then he left the old man's office.

Outside the door, Chen Qiaoshan was also curious, the old man has been in Peking University all his life, according to the time calculation, his husband is at least a figure in the Ming period, since it can be handed down, it is not good that there is an antique calligraphy and painting in his hand, thinking of this, he is very warm, and is thinking about going home to take a good look, but he received a call from the cheap brother.

Thinking that he still had something to talk to Dean Liu, Chen Qiaoshan had to put away his curiosity and turned his head and went to the academy again.

The signing ceremony was over, and Chen Qiaoshan went straight to the hospital office and entered the dean's office familiarly.

"I heard Professor Chen say that you made the old man angry and left? Tell me, what's going on?" Liu Wei was very curious, the old man would not get angry easily, especially in front of people, and he would not throw face at the student, at least he knew that the situation was like this.

Chen Qiaoshan sat down casually, although Liu Wei is the head of the first hospital, but there is a relationship between the senior brothers, and the two have no real entanglement of interests, so it is easy to get along, "No, the teacher is just in a bad mood, and he doesn't like to get involved in this kind of collusion between officials and businessmen." ”

"How do you speak?" Liu Wei's face was a little unsightly, this time in cooperation with the Yabuli Forum, the scholastic court got the largest corporate sponsorship in history, not only that, but the real estate center was also successfully listed, it is said that Guanghua has already had such intentions, but unfortunately limited to funds, the scholastic academy finally won a city this time.

Chen Qiaoshan smiled, knowing that this person was also a tempered person, so he stopped flirting.

"What are you holding in your hand?" Liu Wei also noticed what Chen Qiaoshan was holding and asked.

"Oh, I just got a piece of writing from the old man. Chen Qiaoshan gestured casually, and then quietly put the object in his hand again, just outside Liu Wei's sight.

After all, it is the old man's thing, although he doesn't know the value yet, but he is also a disciple, and he doesn't suffer from widowhood but unevenness, Chen Qiaoshan doesn't want to make his senior brothers suspicious because of this.

Liu Wei is not easy to fool, noticing Chen Qiaoshan's deliberate actions, he smiled and said: "Okay, don't hide it, take it out and take a look, since it was given to you by the old man, I won't fight with you, look at your stingy appearance." ”

"That's what you said, don't blame the old man for being biased when the time comes. Chen Qiaoshan reluctantly took out the blessing word, he was actually very curious in his heart, and he wanted to see what was inside.

Liu Wei was not polite, he walked over and took the word from Chen Qiaoshan's hand, looked up and down, and then peeled off the newspaper outside layer by layer, and finally, a yellowed scroll of painting scrolls inside was exposed.

There is no need to look at it, Chen Qiaoshan can already feel the age of age, and even the shaft head is missing.

Due to poor storage, the paper on the edge has been cracked, Chen Qiaoshan is frowning, the old man seems to be a bad business, how can he keep calligraphy and paintings like this, if this is a rare book or something, it will be ruined.

Liu Wei is also knowledgeable, and after disassembling the outer layer, his movements slowed down, and he carefully put the inner painting scroll on the table, and then slowly opened it.

When the scroll is unfolded, the eight characters of "through the state to help the world, and to promote the line" will jump on the paper.

Chen Qiaoshan is a layman in calligraphy, he only thinks that these words are indulgent and elegant, and they look pleasing to the eye, as for whether it is good or not, where is the good, he can't taste it, the only thing that is certain is that he will definitely not be able to write such words.

Looking at these words, Liu Wei sighed imperceptibly.

Chen Qiaoshan was very sensitive, and hurriedly asked, "Do you know this character?"

"Don't you know?" Liu Wei was obviously angry in his heart, and couldn't help but squeeze a sentence.

Chen Qiaoshan felt a little helpless, he could feel that this character should have a history, but he just got cheap, and it is not easy to deal with others.

Liu Wei didn't say much, and continued to spread out the whole word, and a line of payment was revealed, "Brother Cheng Zun Ya belongs to Xi Jian is twenty-four years old", and then there is a seal, but unfortunately it is very old, it is difficult to identify, even if it can be recognized, Chen Qiaoshan is not recognizable, he does not know anything about seal characters.

"Unexpectedly, the old man gave you this letter. Liu Wei was a little embarrassed.

Chen Qiaoshan didn't care much at this time, and asked with a shy face, "Senior brother, whose character is this?"

Liu Wei glanced at him, although it was a pity, but he still explained: "At this time, during the Republic of China, Mr. Ma Xulun, a professor at Peking University, gave it to Mr. Zhao Yiluan. ”

At that time, there was no term for institutional economics, and this term was first proposed by Mr. Zhao in his graduation thesis at Columbia University, and was eventually widely adopted by the economics community. ”

Speaking of these past events, Liu Wei is also like a treasure, Chen Qiaoshan thought, Professor Yan should have told this history to this senior brother.

"The old man is a student of Mr. Zhao, Mr. Zhao has been teaching at Peking University for more than 50 years, I studied at Peking University, and I have seen his old man, this handwritten book, which was given to the teacher back then, you still don't know, Mr. Zhao's original graduation thesis of Columbia University is now in the hands of Li shares of Guanghua. ”

Liu Wei's tone was a little regretful and a little intriguing.

Chen Qiaoshan didn't know anything about these histories, they were all decades ago, and he didn't know anything except for the parties, but he was quite surprised when he saw this character.

Through the state to help the world, the quality of the line.

It can be said that the mission and responsibility of the economist have been fulfilled in one sentence, especially in the chaotic era of the Republic of China, which is especially rare.

"Since the old man gave you this letter, you should take it carefully, go back and think about it, how to live up to the old man's intentions. Liu Wei seemed to see it, and he had to remind a few words.

Chen Qiaoshan nodded again and again, he still understood this rule, but when he saw the payment, he couldn't help asking: "Is this Ma Xulun very famous, this painting was written in 1924?"

"He was the first Minister of Education after the liberation, is this famous?" Liu Wei's tone was a little unkind, and he said: "Twenty-four is the twenty-fourth year of the Republic of China, 1935, and you don't even understand this?

The dissatisfaction of the cheap senior brother was already overflowing, Chen Qiaoshan could understand his thoughts very well, hurriedly put away the painting, said hello and slipped away, and if he stayed any longer, he was afraid that someone would have some bad thoughts.
