Pei Zhi's voice on the phone seemed to echo in Lin Zhaoxi's ears again.
She began to worry again.
Today is Friday, and the next day is the weekend. According to the agreement between Lao Lin and Pei Zhi, Pei Zhi would come to the Red Star Welfare Institute all day on weekends. And she is going to start her first class as a Math Olympiad teacher.
Saturday, 7:00 am.
Lin Zhaoxi and Lao Lin were sitting opposite each other in the office of his Red Star Welfare Institute, each eating a fried dough stick in his mouth.
Lin Zhaoxi took a sip of soy milk, saw the clock hit 7, and subconsciously looked towards the door, worried that Pei Zhi would no longer come to the Red Star Welfare Institute just like the school's Mathematical Olympiad class.
"Student Lin Zhaoxi." Lao Lin said.
"ah?"
"What did you do again?" Lao Lin asked suddenly after taking a sip of soy milk carefully.
"I have both character and learning, what can I do?"
"Let me tell you, two days ago, I kept a student down, and he was playing some kind of chess in my class. Your face now evokes my memory."
"What memory?"
"What kind of face do children have when they wait for their parents?"
Lin Zhaoxi was still looking at the door, wondering why Lao Lin suddenly asked the children to call him parents, and only then did he understand what he was talking about.
"Hi!" she yelled over her shoulder.
Lao Lin looked at the door and said, "Here we come."
Lin Zhaoxi knew that Lao Lin was teasing her again: "I'll tell you Comrade Lao Lin, do you think I'll believe you?"
"What do you believe?" Pei Zhi's voice sounded.
Lin Zhaoxi jumped up: "You're here, so, so early!"
Pei Zhi stood at the door with a relaxed expression. He was wearing his school uniform as always, with sweat on his forehead, panting slightly, as if he came running.
"Morning." Pei Zhi greeted them and walked in.
Only then did Lin Zhaoxi notice that he was carrying two plastic bags, which contained her and Lao Lin's favorite egg pancakes.
Pei Zhi also noticed the leftover soy milk and fried dough sticks on the table, but he still put them down: "Can you still eat?" He asked.
Lin Zhaoxi and Lao Lin nodded at the same time.
—
The arrival of Pei Zhi made the whole morning "classroom" full of vitality.
Although Lin Zhaoxi always believed that she was responsible for the vitality, she had to admit that when Pei Zhi sat down in this small office, although the atmosphere was peaceful, the study atmosphere became intense.
"Master, I have an idea. I wonder if you are interested in participating." Lao Lin took a bite of the omelette with double eggs in it, and he said this with satisfaction
"have."
Pei Zhi said "yes" without asking what he thought, and Lao Lin took a sip of the soy milk, "Then, check these to see if there is any problem."
Lao Lin moved a stack of papers from the table and placed them in front of Pei Zhi, very simply.
Pei Zhi nodded, thinking that it was Lao Lin's student's homework that he asked him to correct. But when he saw the first page, his expression rarely changed.
That was the draft written by Lao Lin yesterday, and it was filled with "mathematical language" such as g/h, graph=(v, e).
Pei Zhi read a few pages intently, while Lin Zhaoxi rested her chin. Pei Zhi, a high school student, is even more handsome, with a straight nose, and a deep and quiet expression in his eyes.
He can obviously read better, and read it carefully.
To be honest, generally speaking, it is the teacher who checks the homework for the students, or the big cow of the same generation gives the papers to the same generation. It is really strange that Lao Lin asks the students to check the homework for themselves.
Pei Zhi looked at it for a long time, and finally said: "There are many things I can't understand."
"If you don't understand, of course you should learn by yourself." Lao Lin said.
Pei Zhi raised his head: "Okay."
Lin Zhaoxi thinks that your conversation is really concise and to the point.
Lao Lin brought a few books over, and Pei Zhi just flipped through them. He does things in a down-to-earth manner, and when it comes to learning, he doesn't start reading at places he doesn't know, but takes a pen and starts from the beginning.
"Dad, can I check on you too?"
Lin Zhaoxi's eyes suddenly lit up. She was still worrying about how to pass the information to Lao Lin yesterday, but now she has a perfect opportunity.
"The European clothes are dead." Lao Lin dragged out a sentence in English.
Lin Zhaoxi wasn't in the mood to joke with him, so she took the stack of drafts that Pei Zhi had finished flipping through, and read them too.
In fact, she knew that what she was doing now was a little out of control.
Pei Zhi is a genius, and Lao Lin is even more so, and she is just a high school student who is good at mathematics, so it is ridiculous for her to check Lao Lin's draft.
But fortunately, Lao Lin and Pei Zhi were sitting next to her, neither of them would care about such things.
Lin Zhaoxi lowered her head and focused her attention, not thinking about anything else.
From seven o'clock in the morning to nearly eight o'clock, the small office has been very quiet.
She forcibly memorized a lot of content in Strawberry World, and what she has to do now is to find those that are similar to the content she forcibly memorized, compare and correct errors.
This matter is not too difficult for Pei Zhi, who has a good memory, or anyone who has a deep understanding of the problem of graph isomorphism.
But she didn't know much about the relevant content, and suddenly faced with complicated proofs, she couldn't tell where it was.
She can only clumsily recall and compare forcibly, find similarities, and then read them over and over again.
The problem this creates is that she is very slow. It was Lao Lin who said "Mr. Xiao Lin" that made Lin Zhaoxi realize that it was time for her to go to class.
She was still in a state of confusion, she stood up dumbly, and Pei Zhi also looked up at her.
Looking at the boy's questioning gaze, Lin Zhaoxi smiled: "Come on!"
—
Lao Lin's junior high school mathematics Olympiad class... was forced to start a new class because it was too popular.
Lin Zhaoxi used to be a student in a normal school, and she went to the podium in the morning.
Before she stepped onto the podium, she always thought that taking a Math Olympiad class would not be a big problem for her.
But in fact, even though the students Lao Lin taught were only a few short lessons, they were really different.
"Who are you?"
"What are you doing standing on the podium?"
"Where's Lao Lin?"
"I am your new math teacher, my name is Lin Zhaoxi."
"Why are you teaching us?"
"Because I'm good at math."
"We want to test you!"
Lin Zhaoxi: "..."
She always felt that there was a trick in it, but she could only say, "Okay."
It was too late to say it, and every child took out the paper at the same time. Chirping voices came and went: "I'll ask first, I'll ask first!"
Lin Zhaoxi scanned the few rows in front of her, and found a question written on the paper that the children were holding up or putting down. They obviously had been prepared for a long time, rather than impromptu.
"What did Lao Lin ask you to do?" Lin Zhaoxi slandered inwardly, and even asked her to teach graph theory. Isn't that bullshit.
"Old Lin won't let us say it's him!"
"Yes! Old Lin won't let us talk!"
"All right..." Lin Zhaoxi said, "Write your own names on each piece of paper and hand it in. I'll take a look."
The children were very obedient, they wrote their names in a swish, and handed them in in a swarm.
Lin Zhaoxi sorted out the 30 sheets of paper and flipped through them from beginning to end. The Mathematical Olympiad questions that elementary school students can come into contact with at most are only in junior high school. It is not difficult, but some are quite interesting.
The classroom started to be noisy, and the children obviously felt that it would take a lot of work for her to complete the 30 questions, and she would definitely not have to attend this class.
She roughly classified the topics, turned around, picked up the chalk, and wrote down the first question, and then the second question...
The chalk rubbed against the blackboard, making a creaking sound, and the classroom gradually became quiet.
Lin Zhaoxi wrote 6 questions on the blackboard in one go, and when she turned her head, the children all stared at her.
"Then let's start doing the questions. These 6 questions were provided by Jiang Ran, Qu Ting, Xu Xu, Chen Mu, Wang Xiaoxiao, and Bao Yi. Let us thank them."
The children clapped dumbly.
There are also shrewd little students shouting: "Teacher, what are you doing?"
"Let's do the questions together." Lin Zhaoxi smiled, "Of course the questions that everyone worked hard to find should be shared together."
"Ah... shall we do it too?"
"Um."
"But I'm testing you!"
"But I'm done."
"Liar!"
"Really, I've done it all in my head." Lin Zhaoxi smiled, "This class is over half an hour away, you guys try to think about these 6 questions. As for me, write down the answers to all 30 questions , hand it over to each test maker, and let you judge the test paper, is that okay?"
"It seems... can..."
"But I came up with the fifth question, and I know the answer!"
"That's right, so next, you will be the one to answer the fifth question, so you should think about it carefully." Lin Zhaoxi paused, "Every kid who came up with a question has to come on stage and tell others about the question you came up with. Oh question."
"I... I don't know how to do it. This question is so difficult!"
"It doesn't matter. What I did was the correct answer. You can try to understand it. If you don't understand, I will teach you." Lin Zhaoxi smiled.
"Teacher, you are a bit like Lao Lin." A student said.
"Where is the image?"
"It seems a bit shameless."
"Inherited." Lin Zhaoxi said.
The author of the fifth question named Wang Xiaoxiao said "but" for a while, and the other children seemed to have given up resistance and looked down at their own question.
After all, they were students taught by Lao Lin, and most of them should be accustomed to this sudden routine.
Lin Zhaoxi also moved a chair, sat in front of the podium, borrowed a table from the children in the first row, and began to answer questions.
For a while, there were only small-scale discussions and head scratching in the classroom.
In fact, Lin Zhaoxi probably knew that the reason why Lao Lin asked the children to prepare questions for her was because she was afraid that she would not be able to calm down the students in the first class.
So he chose this form similar to free thinking and discussion classes, to let the students understand her strength, and let her and the students gradually become familiar.

Lao Lin's Mathematics Olympiad class usually takes the whole morning.
During the lunch break, Lin Zhaoxi returned to Lao Lin's office with a handful of chalk dust. Pei Zhi and Lao Lin were still immersed in their work, which lasted for several hours.
The shadows of the trees in the yard are dark green, and there are still very light cicadas singing in early autumn.
When they heard footsteps, they put down their pens and looked up.
"Are you back?" Lao Lin said casually.
"Thank you." Pei Zhi said.
Lin Zhaoxi clapped the ashes on his hands, and looked like he had worked hard: "I'm going to eat wontons. I want two bowls, one with shrimp and one with mustard greens."
"Bring me a bowl of mustard greens." After ordering, Lao Lin waved his hand to signal her to leave, probably because he was in a state of work and wanted to work for a while.
"What does Teacher Pei want?" Lin Zhaoxi asked.
"I'll accompany you." Pei Zhi said.
The wonton shop is the one they have loved since elementary school.
After so many years, it is rare that the taste has not changed, and it is still hot at noon.
The only problem is that because the business is getting better and better, the boss has forced an extra third of the tables in the small shop.
Pei Zhi had long legs, Lin Zhaoxi and him sat facing each other, their legs were almost close together.
When the wontons came up, Pei Zhi ate them quietly.
Anyway, they are so familiar, Lin Zhaoxi is not shy, scooping up wontons, while looking at Pei Zhi with his chin.
From the beginning to the end today, Pei Zhi's performance was normal. But Lin Zhaoxi really wanted to ask him, "Does your mother know that you go out to study mathematics?"
This question swirled around her lips several times, but she didn't think of the right time to ask it.
Even after they finished eating the wontons, she was still thinking. Pei Zhi stretched out his hand for the waiter to come over, and ordered two more bottles of Coke.
"Are you still drinking?" Lin Zhaoxi didn't quite understand.
"Let you watch it for a while."
"!!!" Lin Zhaoxi blushed instantly.
Maybe it was because Pei Zhi saw her anxiety, so he made this joke.
Lin Zhaoxi was still a little nervous at first, but soon calmed down a lot. Holding the half-drinked Coke, she chatted with Pei Zhi as they walked.
"What do you think of Comrade Lao Lin's homework?" she asked.
"It's okay." Pei Zhi thought for a while, and then said, "Verification is a meticulous job and it takes time."
"Then do you have time?" Lin Zhaoxi paused, "If you come out today, don't you need to accompany your mother?"
Pei Zhi stopped and looked at her.
"Why didn't you tell me at summer camp?"
"The incident happened suddenly, and I didn't think it through." Pei Zhi said.
"No." Lin Zhaoxi shook her head, "My Brother Pei is not the kind of person who would 'think about it'."
Pei Zhi took a sip of Coca-Cola and continued to walk forward: "You want to tell the truth?"
"The European service is dead!"
"At that time, you were very busy and worked hard every day. If I told you this, you would obviously have to devote a lot of thought to caring for me." Pei Zhi said.
"You think that for problems that cannot be solved, caring itself can't solve the problem, so let me not waste all these time and thoughts on you?"
"That's right."
Lin Zhaoxi stopped and looked at Pei Zhi seriously.
She didn't know if what Pei Zhi said was the truth, or if he chose a seemingly reasonable explanation to cover up the promise he made to his mother.
She thought for a while, hooked her fingers at Pei Zhi, and said, "Come with me."
She took the lead, walked into the street store, spent a huge sum of 6 yuan, and bought the most expensive cold drink Menglong at the moment, and handed it to Pei Zhi: "Please eat."
Pei Zhi held the cold drink and looked at it for a while, then took money out of his pocket.
"You have to learn to accept other people's kindness." She said seriously.
Like you told me in the future.
