After calming down, Professor Wang said, "Although this is just a joke told by Chen Qiaoshan, the joke itself has a certain economics theory."

There was a burst of laughter from below, but fortunately, it was not long and it soon became quiet again.

"The family itself is an important research object in economics, and it is a cross-disciplinary topic of sociology and behavioral economics research."

"In 1992, Professor Gary Becker of the University of Chicago won the Nobel Prize in Economics for his pioneering definition of family economics. Of course, this is just one aspect of economics research."

"At present, economics has perfectly explained issues such as parent-child relationships, husband-wife relationships, and even problems such as extramarital affairs have been published. However, the economic issues involved in sibling relationships are still a private place."

"If you are interested, you can put some effort into this area and you may be able to achieve considerable results."

There was another burst of laughter below, and Chen Qiaoshan could only smile bitterly. After all, he had made mistakes first, so it was reasonable to be teased.

Professor Wang took out a piece of materials from the lesson plan and flipped through it, then continued: "Student Chen, you should know the attendance rate this semester. Did Teacher Zhou talk to you, right?"

Chen Qiaoshan had no choice but to nod.

"That's good. Since even your counselors have pleaded for you, I am willing to give you a chance. According to Teacher Zhou's conditions, as long as you meet the requirements, I will not pursue your absence from class."

Chen Qiaoshan was prepared in his heart, so he could only do his best this time, otherwise he might be warned by his studies.

When something happened, if I really wanted to warn again, maybe there would be another storm.

"Also, I have great expectations for you. If you can go further, I can consider letting you get rid of the exam in this course." After that, Professor Wang added with a smile, which seemed to be a joke, but anyone could hear the affirmative meaning in his words.

The two of them were playing a puzzle, and the students below were confused when they heard it, but as soon as the following sentence came out, the classroom suddenly became noisy again.

The excellence rate of each course is limited. On a campus full of academic masters, competition is fierce, especially for those who are preparing to study abroad or promote research, grades are an unavoidable topic.

It is definitely a huge temptation to be exempted from the exam.

Professor Wang raised his hand to stop the discussion below and said with a smile: "I know you have questions in your heart. I will tell you about the specific requirements and publish a Chinese-type economics paper. I can give you the qualification to be exempted from the exam."

"I would like to emphasize first that I treat everyone equally. No matter who you are interested, you can try it."

After saying that, Professor Wang did not mention anything else and started teaching this class directly, leaving only a room of dumbfounded students.

Chen Qiaoshan once again became the focus of everyone's attention, and he had no special feeling. Sooner or later, the paper will be known, and it will definitely not be concealed.

"Brother, okay, now we're going to start writing papers." A listener sitting next to Chen Qiaoshan took the initiative to mess with him, "Hey, no, your name sounds very familiar. Have we seen it somewhere?"

Chen Qiaoshan glanced at the man, just smiled, and didn't explain anything. He even made a fuss and couldn't be famous, and he didn't know whether it was a good or a bad thing.

The two classes ended soon, and Chen Qiaoshan was surrounded by a group of classmates.

"Dashan, don't lose your chain. This semester's professional English exam is out of the exam. Just work hard to get economics together."

"That's right, I'm optimistic about you, isn't it just a journal? That's not a problem. The professors next door have made you mess up, so this time it will definitely be fine."

...

Facing a group of classmates who were not interested in the big deal, Chen Qiaoshan was also tired of dealing with it. He finally got out of the crowd, but was stopped by Li Xiaolin.

Chen Qiaoshan had long wanted to talk to her. This person was very strange. He seemed to be paying attention to him all the time, which made people feel uncomfortable. There was also the girl who looked very similar to Xiaowu when I saw her last time.

Although Li Xiaolin said that he didn't know Zhang Yiyi, Chen Qiaoshan always felt something was wrong. The man looked so much like Xiaowu, and it was a big doubt that he didn't even tell Yan Xiaoqin about entering the police station, but Li Xiaolin knew it again.

Li Xiao-Lin glanced at him and asked, "Are you okay?"

"What can I do?" Chen Qiaoshan was a little confused. After thinking about it, he realized that she should be asking Xinhua. He couldn't help but wonder: "How do you know about me entering the police station?"

"What do you think?"

Chen Qiaoshan didn't want to go around the corner, but he had no choice but to say, "What Zhou Sheng told you?"

Li Xiaolin didn't comment. She looked around and said, "Why don't we go out and talk."

There were people coming and going around, and it was really not suitable to stay here. Chen Qiaoshan looked at his watch and had plenty of time. "Okay, find a place to chat."

"Where is Yan Xiaoqin, she won't come here, right?"

Chen Qiaoshan said: "Come on, do we still need to keep the matter confidential?"

"That's not necessarily." Li Xiaolin seemed to be smiling, as if she suddenly remembered something. She suddenly asked: "By the way, Zhang Yiyi you mentioned last time, who is she you are?"

"Do you know her?" Chen Qiaoshan was a little surprised. She took the initiative to raise this topic. It seemed that she was prepared for it.

Li Xiaolin didn't say anything and walked out first. There was no way, so Chen Qiaoshan had to follow him.

"Find a place to sit down and chat?" Li Xiaolin asked on his own initiative after leaving Guanghua Tower.

"Forget it, just have a walk." Chen Qiaoshan refused. He heard Zhang Yiyi's name again. He really didn't want to waste his time.

Chen Qiaoshan did not intend to pursue the events that happened to the Chen family in the past.

Twenty years have passed since the grudge between the Zhang family and the Chen family. The two families have long cut off contacts, and the only thing they are involved is Zhang Yiyi.

Chen Qiaoshan was just curious about this nominal sister, but as for other emotions, he really owed nothing.

He is not as entangled as the old lady of the Chen family and Chen Weiguo. He is a person he has never met. Even if he is related to blood, his emotional alienation is only a little different from strangers, let alone his situation.

The old scholar Zhang and his wife have been staying at Tsinghua University since they returned to the city. It is no secret that Zhang Ziyu's whereabouts were. She graduated from Tsinghua University and was assigned to the Capital School of Economics, which is now the University of Economics and Trade.

In this information society, it is not difficult to find out these things, especially famous scholars like the Zhang couple, but Zhang Yiyi has no news at all.

After all, Zhang Yiyi is the blood of the Chen family, and the Chen family has never forgotten this relative.

Especially the Chen family’s grandma, Chen Xi swore to take the entrance exam for Peking University, and it was also the old lady who worked hard behind the scenes. The old lady still remembered this granddaughter whom she had never seen for many years.

It is actually not difficult to find Zhang Yiyi. The easiest way is to come to him, but Chen Qiaoshan did not intend to do so.

The two families have long stopped interacting with each other, and the parties have their own lives. It is meaningless to worry about right and wrong, and it will only break the life that the two families have calmed down.

Chen Qiaoshan didn't want to act in Yanjing to recognize relatives. He had nothing to do with the Zhang family. Tao Xiuying was his biological mother and three sisters were the real relatives.

As for the Zhang family, they were just strangers, only Zhang Yiyi was an exception.

...

The two of them didn't go far, but took a turn and arrived at the Centennial Memorial Hall. The nearby area was very quiet and no one disturbed them.

"Chen Qiaoshan, do you still have a sister?" Li Xiaolin asked curiously.

"Yes." Chen Qiaoshan couldn't help laughing when he thought of his sisters.

If the jokes about no profit investment are heard in the ears of the three of them, he would have to be said again. Thinking of this, he had a few more emotions of separation. He had only son in his previous life, but suddenly had three younger sisters in his life. It felt different.

"I have three sisters, three." Chen Qiaoshan stretched out three fingers, gestured an OK gesture, and emphasized it specifically, very proud.

Chen Qiaoshan suddenly realized that the three sisters were more like three daughters, and he always wanted to plan a future for them.

"It's really three sisters, one is a mom?" Li Xiaolin was a little curious.

"Yes." Speaking of this topic, Chen Qiaoshan couldn't help but smile, "If you have a chance in the future, may you meet them?"

Li Xiao-Lin's face was a little surprised, "Is that true?"

Chen Qiaoshan glanced at her and explained with a smile: "It was a lucky thing for me to be admitted to Peking University. My sister's grades are better than me. Now she is a senior and a senior high school student. She returns to the top in the grade and has the same goal as Peking University."

Of course, Xiaowu was automatically ignored by him, and the grades were not mentioned for now. The age gap was there. A post-80s and a post-90s sister, Chen Qiaoshan sighed in his heart, and there would be trouble in the future.

But thinking about the third and fourth brothers, he became happy again: "Don't think I've also been admitted to Peking University, and I'm even worse than my sister. Look at it, they will definitely go to Peking University."

Chen Qiaoshan is full of confidence, Chen Xi and Chen Wan are already extremely outstanding and work hard. According to the current trend, even without his help, she may not be able to get into Peking University.

"Why don't you consider Tsinghua University?" Li Xiaolin asked again with a little strange.

"Our family doesn't like Tsinghua very much." Chen Qiaoshan said jokingly.

Li Xiaolin was stunned for a moment, and after a while, he asked, "Chen Qiaoshan, do you have a sister?"

Chen Qiaoshan looked at Li Xiaolin who was close to her, hoping to see something from her eyes, but except for vague curiosity and exploration, there was no other emotion.

"Yes." Chen Qiaoshan said very surely, "I have many cousins."

Li Xiao-Lin frowned, "I'm talking about my own sister, not my cousin."

"That's not." Chen Qiaoshan vetoed, "My mother gave birth to four of us brothers and sisters."

Chen Qiaoshan could see clearly that Li Xiaolin must have known something, otherwise he would not have tried it repeatedly. He was also a little curious about what her identity was.

Li Xiaolin didn't give up, and she asked again: "Can you tell me about your family?"

"What do you want to know?" Chen Qiaoshan was not in a hurry and accompanied her around in circles.

"For example, your parents, and your family."

"That's it." Chen Qiaoshan smiled and said, "My family is in the rural areas of Henan Province. Since I beat my grandfather's generation, I haven't gone out for three generations. My parents are authentic farmers. They farm at home and do all day long. There is nothing to say. Otherwise, I'd better talk about my three sisters. The three of them are very interesting."

Li Xiaolin was a little depressed. She made up her mind this time, but this guy seemed to have seen through it and kept pulling it on the three sisters, which made people anxious, but there was no way.

"Can I ask, what do you do when you skip classes often?" After thinking for a while, Li Xiaolin didn't understand it, so she simply changed the topic.

This topic is a bit changeable, and Chen Qiaoshan is a little strange. He never mentioned it on campus forums and investment in Kangsheng, so he did not hide the stock trading, but only a few people in the dormitory knew about it.

"Go outside to make money. You know that Yanjing's consumption level is not low. Besides, I have a girlfriend, and my family is not well-off, so I can only find a way for myself." Chen Qiaoshan joked.

Li Xiao-Lin muttered, "No wonder, I always see you running."

"What?" Chen Qiaoshan didn't hear it clearly and asked afterwards.

"Nothing." Li Xiaolin shook her head, "How about this. If you want to find a part-time job, I can introduce you to it. It won't delay class time, and the salary will definitely be more than you earn when you work odd jobs."

Chen Qiaoshan was speechless. He looked up and down at his clothes and couldn't help but smile bitterly. Li Xiaolin obviously took it seriously.
