Just turned over a new leaf and became a wise and intelligent student

Chapter 67: The Pearl is Covered in Dust, You Were Born Late
Neither Xu Qingshan nor Teacher Ji was aware of the changes in external things.

The first-year high school students are also well-behaved. With these two big Buddhas here, they don’t make any noise or noise.

"Phew, okay."

Xu Qingshan stopped writing, let out a long breath, subconsciously looked up at the clock, and was stunned for a moment.

He didn't even notice the passage of time just now, and it turned out that more than an hour had passed.

Normally at this time, their senior year classes were over and he had already finished running.

"hiss"

Teacher Ji took a deep breath, and the students sitting in the front row under the podium felt the temperature around them drop by several degrees.

"The inequality recursion is changed to the equality recursion, but because the scaling can only get the upper bound that cannot be equal, it does not conform to the convex sequence. Therefore, it is analyzed that all the numbers of bk should reach the same minimum when n tends to infinity, and then the recursive relationship of ak can be minimized in steps."

Teacher Ji's eyes moved rapidly and repeatedly, and he muttered rapidly something that the freshmen around him could not understand at all.

"In the same order, use Chebyshev's inequality to reduce the size. The goal is to prove that max(1≤i≤n)bi tends to 0 when n tends to infinity."

"I split the main part and the small part, calculated the sum of the two parts, and controlled the sum to zero, so I used a simple limit."

Teacher Ji slapped his palm on the paper full of formulas.

"This idea is so clear, so clear indeed."

"Xu Qingshan, have you really never studied mathematics competition?"

"Really? I didn't study hard before. Is it a bit late now?"

Xu Qingshan took a look at the test paper. After Teacher Ji had explained the knowledge points and simple ideas of mathematical analysis to him, he felt that this question was quite routine.

Teacher Ji stared at Xu Qingshan with sharp eyes, but when he remembered the identity of the boy in front of him, his eyes darkened.

"It's too late, alas."

Teacher Ji sighed regretfully.

He believed that he had met a mathematical genius with great potential.

But the timing of this encounter was not auspicious.

October of the first semester of senior year meant that Xu Qingshan no longer had the opportunity to participate in the competition.

The process of high school mathematics competition is very long.

The preliminary round is held from April to September each year and is organized by each province at different times. Each province has approximately tens of thousands of participants, and the number of contestants who ultimately enter the semi-finals varies.

In the league stage, in September of each year, each province will select the provincial first, second and third prizes, and the province will grade the papers. The first prize will be sent to the organizer for re-evaluation, and the final result will be announced by the China Association for Science and Technology. At the same time, each province will select provincial team members based on the ranking, and the number of provincial team members will be determined by the performance and results of each province in the CMO (China Mathematical Olympiad) last year.

The finals stage, also known as CMO, is held in November. The first, second and third national awards are commonly known as gold, silver and bronze medals, and the top 11 in the national competition can enter the national training team.

During the training phase, in March of the following year, the national training team will conduct two rounds of extremely difficult internal selections to determine a 3-member national team to participate in the IMO (International Olympiad).

The final IMO will be held in June-July of the following year, with a maximum of six contestants and two team leaders from each country.

Although the student requirements are to be under 20 years old and have a high school education, the contestants are basically in the first and second year of high school.

Longjiang Experimental has put a lot of effort into establishing a competition team, from nothing to now steadily winning provincial awards and aiming to win medals. The development can be described as difficult.

Teacher Ji is also the founder and head of the Longjiang Experimental Mathematical Competition Team.

He looked at Xu Qingshan in front of him, as if he was looking at a bright pearl covered in dust, meeting the right person at the wrong time.

Although it's not quite right to say that.

But as a science student who is not good at love, Teacher Ji finally understood the sincere emotion contained in the sentence "I was born before you were born, and you were born when I was old."

If I had discovered Xu Qingshan when he was in the first year of high school.

If, this year's senior high school math teacher is him.

如果
Damn Duan Yongming!

It would have been better if Teacher Ji didn't think about it in detail. The more he thought about it, the angrier he became.

In Mr. Ji's opinion, if a genius like Xu Qingshan who showed such potential and learning ability was well trained by this sweeping monk, he would at least be a rising star in the competition who could secure bronze, silver and strive for gold.

This is the person who can establish himself as the first person in the history of Longjiang Experimental Mathematical Competition Team!

Wow ya ya!

Duan Gou and I will never coexist!

When Xu Qingshan heard what Teacher Ji said, and saw that his face was uncertain and there was anger burning in his eyes, he was a little unsure.

"It's okay if it's late. I can just learn some simple basics to exercise my thinking. In fact, this is the first time I found that mathematics is actually quite interesting."

Xu Qingshan took the initiative to enlighten Teacher Ji. This teacher is actually quite good. Although he is a little bald, he is still very serious when explaining knowledge points and questions to himself.

Xu Qingshan was not lying. He had never studied mathematics seriously in his previous life. After graduation, he even had to use a mobile phone calculator to do addition, subtraction, multiplication and division, and he had to count the dates with his fingers.
It’s no wonder that some people say that most people’s academic peak is the college entrance examination.

"You and me. Sigh."

After listening to Xu Qingshan's words, Teacher Ji wanted to say something, but something was stuck in his throat.

He was already adjusting his mindset.

Xu Qingshan's words upset him again.

"Teacher, what do you think of the material cost?"

Xu Qingshan asked tentatively, these materials are not cheap.

"No thanks, just take them all. I'll give you new ones when you're done. Do you have a phone number?"

"Have."

"Okay, here's my phone number. If you have any questions while doing the test, you can always call me. If you have a lot of questions, you can always come to Houde Building to find me."

Teacher Ji wrote his name and phone number on the paper, and Xu Qingshan took a look at the name.

Teacher Ji’s name is very poetic: Bai Yang.

Xu Qingshan subconsciously glanced at Teacher Ji Baiyang's extreme intelligence again, and suddenly felt that there was indeed a kind of beauty of the Baiyang tree rooted in the Northwest.

"Go ahead, it's about the same time. I happen to be here to teach evening classes."

"Teacher, don't you need to go eat?"

"I'm not hungry. You should go back and eat. Your family must be waiting anxiously. They know you can do it right after listening to it, so they let you come for evening self-study."

Ji Baiyang was very melancholy.

Putting aside his anger towards Duan Yongming, Teacher Ji is still quite gentle.

"It's okay, I'm not hungry either. Then teacher, I'll leave first?"

Xu Qingshan had already spotted the girl sneaking around outside the Grade 1 Class classroom.

"Go ahead, I just want to be alone."

Jingjing? Miss our beautiful class teacher?

Xu Qingshan interpreted it in a distorted way and made malicious criticisms.

I have already walked out the door.

"Oh, that's right."

Teacher Ji seemed to have just remembered something and was about to call Xu Qingshan, but he saw a girl outside the classroom looking up and handing the wrap in her hand to the boy with both hands.

He withdrew his hand and stopped talking.

"Ugh."

Unable to help but sigh again, Teacher Ji continued to correct his students' homework.

After the boy outside the classroom left, he looked at the girl who brought food to the boy and was a little surprised.

"Tong Tong, come here."

Teacher Ji called out softly to Tong Tong who was about to return to his seat.

Tong Tong was a little reserved.

"teacher."

"Do you know Xu Qingshan?"

"Well he is my brother."

"Oh"

The conversation between teacher and student was a little awkward, but Teacher Ji didn't care why Tong Tong's surname was Tong and Xu Qingshan's surname was Xu.

Teacher Ji's eyes suddenly moved and he pushed up his glasses.

"Come on, Tong Tong, I remember you got full marks in math for both the entrance exam and the monthly exam. I'll explain the key points of this question to you, and you can try to do it."

Teacher Ji pulled out another paper from the side, which was exactly the same as the one he had just given to Xu Qingshan.

He put his fingers on the paper and looked at Tong Tong hopefully.
