Chapter 86 Chengjiazhuang Tutoring School
I called for two minutes, waited for more than ten minutes, and was watched for more than half an hour.
After coming out of the post office, Cheng Xuyuan breathed a sigh of relief. It was really uncomfortable to be surrounded by people.
Originally, he came to Liguotun Commune and planned to buy some things, but in this situation, he didn't buy anything and rode his bike directly back home.
The winter sun shines on the fields, and the fields of winter wheat droop their heads, looking listless.
Occasionally, someone would pass by on a bicycle on the bumpy dirt road, but most of the time, the surroundings were deserted.
When I got home, my mother Wang Guilan complained, "Why did you go to the commune in such a cold weather? Come inside and warm yourself by the fire."
"Look at your face, it's all red from the cold!" Hearing this kind of happy complaint, Cheng Xuyuan smiled and did not argue.
Just as he came to the stove to warm his hands, he heard someone say, "Excuse me, is Cheng Xuyuan home?"
Hearing this, Cheng Xuyuan walked out of the room and saw two young men in khaki Zhongshan suits standing in his yard.
Cheng Xuyuan had an impression of these two people. They were educated youth at the educated youth point.
One of the two people is called Liu Jiankai and the other is called Ma Guangzhong.
But Cheng Xuyuan didn't have much friendship with the two people, so why did they come to visit at this time? "Do you have something to ask me?" Cheng Xuyuan asked with a smile.
Liu Jiankai was holding a book in his hand. When he saw Cheng Xuyuan coming out, he hesitated for a moment, then forced a smile and said, "Cheng... Cheng Xuyuan, we are learning math today, and there is a problem that we can't solve, so I would like to ask you for help."
At this point, he said with a hint of pleading: "Just help us explain it. It won't take up too much of your time."
When someone came to ask for help with math problems, Cheng Xuyuan did not refuse: "What's the problem? Let me see if I can answer it."
Liu Jiankai quickly opened the book and said, "It's this problem of finding the area of a triangle. No matter how hard we try, we can't find all the conditions."
Cheng Xuyuan took two glances at the question and immediately understood.
This is a geometry problem, and in terms of difficulty, it is only at the junior high school level in later generations.
He did not give an answer immediately, but after a moment's hesitation, he said, "The difficulty of this question lies in the lack of the length of one side."
"It's hard to find it directly, but if we draw an auxiliary line here, then next..."
Liu Jiankai and Ma Guangzhong listened to Cheng Xuyuan quietly, and from time to time, they would ask a few questions.
These questions were not difficult, so Cheng Xuyuan answered them one by one.
It only took five minutes for Ma Guangzhong and the others to understand the question.
After checking the calculation himself, Ma Guangzhong couldn't help but say, "Cheng Xuyuan, no wonder you scored so high in math! We spent the whole morning trying to figure this out, but now that you've explained it, we understand everything."
At this point, he glanced at Liu Jiankai and continued, "In fact, we don't know whether we got one of the questions right or wrong. How about you show it to us again?"
Facing Ma Guangzhong's uneasy eyes, Cheng Xuyuan sighed.
Although he was not an educated youth, he knew very well what these young people were thinking through his memories.
They study hard, they work hard, all because they want to change their own destiny.
Cheng Xuyuan really couldn't say no to such a young man.
"Let's study together. This is not the place to talk. Let's go inside. It's warmer there."
In response to Cheng Xuyuan's invitation, Ma Guangzhong and Liu Jiankai looked at each other and followed Cheng Xuyuan into the room.
Wang Guilan was cooking in the house. When she saw two people coming in, she greeted them. The two people also greeted Wang Guilan very politely.
More than forty minutes later, the two people left Cheng Xuyuan's house contentedly.
All their questions were answered, and both of them looked at Cheng Xuyuan with admiration.
The difficult problem that had troubled the two people for a long time was easily solved by Cheng Xuyuan. Moreover, after Cheng Xuyuan's explanation, the two people were able to apply the solution to other problems by analogy.
"No wonder Cheng Xuyuan was able to be admitted to Yenching University. He is indeed much better than us." Ma Guangzhong sighed as he walked out of Cheng Xuyuan's house.
Liu Jiankai said: "Who said it wasn't true? I used to doubt whether he had some luck involved, but now it seems that he really has the ability."
"How did he learn all this knowledge?"
Ma Guangzhong waved the book in his hand and said, "Don't talk about this now. I think the most important thing for us now is to take advantage of the time when Cheng Xuyuan is home to tutor him."
"Once he leaves, there will be no such opportunity."
"Yes, yes, you are right." Liu Jiankai said, "Let's go back and find all the problems that we couldn't solve before, and ask him for advice."
Ma Guangzhong was a little excited at first, but after hearing what Liu Jiankai said, he suddenly seemed to have thought of something and said, "Cheng Xuyuan has an average relationship with us. It's a favor for him to explain two questions to us. Why should we let him explain questions to us all the time?"
Liu Jiankai frowned, he didn't know how to answer this question.
"My family sent me some cookies a few days ago. How about I bring some to him? It will be a token of our appreciation."
Liu Jiankai said with a hint of reluctance. After all, those biscuits were very rare and he usually couldn't bear to eat them.
Ma Guangzhong said: "My mother asked someone to bring me some dried fish from our place. I will bring some back later."
While the two were talking, they returned to the educated youth site and saw Chen Jiang and several others gathered together, as if discussing something.
"Jiankai, come here and take a look. Why can't I solve this problem?" A male educated youth shouted loudly when he saw Liu Jiankai.
Liu Jiankai walked over and found that they were actually doing the same question that he had just asked Cheng Xuyuan for help.
He said directly: "Yumo, you can't solve it by force. You should make an auxiliary line. Then the problem will be simple..."
Chen Jiang and others waited for Liu Jiankai to finish speaking, and their eyes widened.
The problem that had been bothering them for a long time was solved by Liu Jiankai. How did he become so awesome?
Especially Chen Jiang, who always felt that Liu Jiankai's math was not as good as his.
But now, he actually did it before me.
"Jiankai, you are really awesome. How did you come up with this idea?" He Yumo said excitedly to Liu Jiankai.
Liu Jiankai spread his hands and said, "Actually, I don't know the answer to the question you mentioned."
"Guangzhong and I just couldn't figure out the problem, so we went to ask Cheng Xuyuan for help. He just took a look at it and gave us a solution."
Liu Jiankai said: "He is the one who is really amazing."
He Yumo asked, "He really did it after just two glances?"
"I would lie to you about this!" Liu Jiankai said, "Guangzhong went with me. If you don't believe me, you can ask him."
Ma Guangzhong said: "It's true, Cheng Xuyuan only took two glances and then did it."
"I plan to ask him questions about the questions I can't answer."
As he spoke, Ma Guangzhong walked towards his room.
He Yumo immediately said to Chen Jiang: "Old Chen, should we also go to Cheng Xuyuan for advice?"
"After all, opportunities are rare!"
Chen Jiang snorted and said, "You go if you want to go. I, Chen Jiang, will not go to find Cheng Xuyuan."
He Yumo wanted to persuade him again, but Chen Jiang had already turned and left.
Lunch at Cheng Xuyuan's house has begun to return to normal, with salted radish and yellow flour steamed bread, plus a bowl of cabbage soup for each person.
Although he was prepared for this situation, Cheng Xuyuan still found it a little difficult to swallow. After all, the yellow flour steamed bread was really irritating to the throat.
However, seeing that even Cheng Xiumiao was eating with gusto, Cheng Xuyuan had no choice but to bite the bullet and eat the two yellow flour steamed buns.
At this moment, he suddenly doubted that his decision to stay at home until the New Year was really a test.
In the afternoon, Cheng Xuyuan spread out paper and pen, ready to write more of "Desire".
He received two months' advance on the royalties for "Things About the Ming Dynasty", which meant that after returning to Yanjing, he would have to live on his salary.
With that money, I can’t even eat more.
But before he could write two words, someone came to him. They were still educated youths from the educated youth point, and they asked about the problems they encountered in their studies.
Facing those eyes full of curiosity, Cheng Xuyuan wanted to say no but finally swallowed it back.
As a result, more and more people gathered around him, and when one left, two would come.
Throughout the afternoon, Cheng Xuyuan's house was packed with people standing.
One question after another made Cheng Xuyuan feel that he didn't even have time to go out for a rest.
As it was getting dark, Cheng Xuyuan felt physically and mentally exhausted.
After an afternoon of explanation, Cheng Xuyuan discovered that although these educated youth were studying hard, they all had the same problem: their foundation was too poor.
For this reason, many problems that should not have occurred have recurred.
It was very uncomfortable for him to speak! And those who listened to him didn't quite understand.
Unless I find a reason to hide away, otherwise, looking at the attitude of these educated youth, I will have to spend the next month with them.
Although it is easy to say no, Cheng Xuyuan really finds it hard to say no to these people who want so badly to change their destiny through their own efforts.
It seems that he is still not ruthless enough! He thought for a moment, and then said to the educated youth who were about to leave: "If we continue to talk about this in a haphazard way, I think it will only have a limited impact on everyone's improvement."
"How about this? Starting tomorrow morning, I will give you a systematic lecture on algebra and geometry from the Mathematics, Physics and Chemistry Self-Study Series in the barn of our brigade."
"It starts at 9 a.m. If you are willing to learn, just go there and attend the class on time."
Originally, the best place to give lectures was the brigade's primary school, but the school had not yet closed for vacation, so there were naturally no classrooms for Cheng Xuyuan and his friends to use.
Although the cattle shed smells bad, its advantage is that it is large and the brigade members usually hold meetings there.
After hearing what Cheng Xuyuan said, the educated youth who were about to leave were stunned for a moment.
They stared at Cheng Xuyuan in a daze, wanting to say something but unable to utter it for a moment.
After the educated youth who were talking a lot left, Cheng Xuyuan prepared to go to his second grandfather's house. After all, he had to borrow the brigade's barn to give classes, so he had to tell his second grandfather, the head of the brigade, about it.
However, just as he was about to leave the house, his second grandfather Cheng Fulai came over and said to Cheng Xuyuan, "Dayuan, your uncle sent someone to tell you that the time for the physical examination has been set in three days, and asked you to go to his house one day in advance and wait."
I have to admit my mistake to all the big guys. I stayed out playing with my children on Children's Day and stayed too late, so the update was not written in time, which delayed me by two hours. I was wrong and I sincerely apologize. I also implore everyone to let a grown-up child like me have a holiday as well. I will resume updating from tomorrow.
