School belle, please respect yourself: I am a serious person.

Lu Li is very big now.

One left and one right, two wolves around, forget it.

This game, it seems to be a bit different from what he thought, right?

Shouldn't this kind of international competition question be difficult?

To make this kind of question, you have to sacrifice at least a year or two of hair volume, right?

How does it seem so simple?

Is something wrong?

"What's wrong, Lu Li?" Chen Hai saw the doubt in Lu Li's eyes, and then put down the question he had been holding in his hand.

Originally, this lesson was specially given to Lu Li, but now that Lu Li has doubts, of course he has to explain it clearly to Lu Li.

After all, Lu Li will be a little more at that time, so he can worry a little less.

"No, Director Chen, is this a true question?" Lu Li quietly slapped off Nan Jinping's paw that was about to reach out to him and asked.

"That's right, the real questions of the previous years." Chen Hai nodded, "You're only a sophomore, and it's normal that you don't understand, don't be in a hurry, take your time." There are still two months to sign up. "

No, I..."

Chen Hai could understand Lu Li's feelings.

At that time, he was also admitted to Tianjing University through the National Mathematics Olympiad.

So, before he knew about the game, he was confident in himself.

However, when he actually got the question of the competition, he was dumbfounded.

That topic is completely different from the Olympiad.

At that time, he was really devastated and even doubted what he had learned in mathematics.

At that time, it took him a long time to recover.

And now, it is obvious that Lu Li is in the same predicament as he was back then.

Therefore, Chen Hai decided to give everything to help Lu Li.

Because, in Chen Hai's eyes, Lu Li is completely his younger self.

Although, he is a little more handsome than himself...

My girlfriend is also a little better looking than my daughter-in-law...

But, just a little.

This kind of detail doesn't matter!

He was sure that a mathematical genius like Lu Li must have fallen into deep self-doubt at this moment.

But fortunately, while he was studying for a master's degree, he took a degree in psychology.

Although he was thinking about how to make his girlfriend happy...

It doesn't matter either!

Isn't that just right now?

"Lu Li, I have also encountered this situation with you." Chen Hai nodded, trying to make his tone appear ordinary, "At this time, there are three sentences that are very important to you, I hope you can remember them."

"First, we must unswervingly adhere to the principle of a good attitude." Chen Hai didn't wait for Lu Li's answer, and continued.

Lu Li couldn't bear to interrupt Chen Hai.

He saw it, Chen Hai probably thought he was confused?

Forget it, it's good intentions after all.

Lu Li nodded, "Second?

"Second, regretting the past leads to depression, and being locked up for the future leads to anxiety, so you must live in the present." Chen Hai continued.

Lu Li: ?????

What the hell is this???

"Third." Chen Hai ignored Lu Li, he picked up the water glass, took a sip of water, closed his eyes and thought for a while, and then said, "When you are anxious, don't try to figure things out, don't try to sort out the cause and effect. At this point, it's not the thing itself that goes wrong, nor your logic, but your emotions. Emotions are not controlled by logic, emotions are controlled only by emotions. All your confrontations, especially thinking under emotions, add fuel to the fire. At this time, give up thinking, take a deep breath, go out for a walk, eat something you like, do something that is meaningless but can make you happy, until good emotions grow and until your heart is calm.

After finishing speaking, Chen Hai seemed to breathe a sigh of relief, picked up the cup and took another sip of water.

"No," Lu Li was a little numb, "Director Chen, why don't I think these words are important?"

"No, it's important. The first and second questions are compulsory for multiple-choice questions, and the third is a compulsory test point for question and answer questions. If you memorize these three sentences, you will get at least 15 more points if you have memorized the psychology exam. Chen Hai put down the cup and said to Lu Li seriously.

Lu Li: ...

I shouldn't have believed you!

Gan!

Chen Hai also seemed to realize that he had slipped his mouth, his face was a little embarrassed, and then he waved his hand, "Anyway, that's what it means, I know these questions are difficult, but you must not doubt your mathematical talent, we have never learned these problems Xi, so it is normal to be difficult." "

But, Director Chen..."Lu Li stopped talking, "I think... Isn't it hard? "

“？" Chen Hai's eyes widened suddenly, "You say it again?"

"It's like question F." Lu Li picked up the paper in his hand, "cost of privacy, for task one, build a comprehensive pricing model, and then develop the price point coefficient and personal property assessment if you use α and β respectively

β α..." And then use this to evaluate

...""Then, turn this function into a graph..."

"Isn't the answer obvious?"

"Then there's task two, which is a little bit more cumbersome. On the basis of the comprehensive pricing model established in task 1, add a return cost, and then build a nine-point simplified diagram..."

"Then there's task three. In fact, after the first and second tasks were made, the third task was almost given for nothing. Combine the models built from the first two tasks and build a PI reflection model..".

"Task four can be a bit more cumbersome because it uses spatial integrals. Here's what the formula looks like... Okay, it's listed. Then with the definition of the integral of the type 2 curve, it is converted into a definite integral... No, it's a bit computational, it's easier to use the Stokes formula... Well... Wait a minute, the amount of calculation is a bit large..."

Looking at Lu Li's figure holding chalk and writing and drawing on the blackboard, Chen Hai was completely stupid.

When he was competing in 18 years, this question happened to be the topic of the competition with his students, so he was very familiar with this question.

Because of this, the shock in his heart is even more incomprehensible.

The solution in front of me is clearly the solution that won the international grand prize in 18 years!

No, it's not.

Lu Li's solution is even better than the one that won the grand prize!

Whether it is the establishment of mathematical models or the optimization of the amount of calculations, all aspects have crushed the grand prize of that year!

So, there is no such thing as copying answers!!

No, it's a sophomore???

Fake barfuck????

This is a fart of its own!!

Why is there such a big gap between myself and him!!

Gan!

I even thought he was confused.

Hehe, confused P.

Listening to Lu Li's voice at this moment, Chen Hai remembered Lu Xun's words.

The joys and sorrows of people are not the same....
