The train driver in the courtyard

Shocked the entire international mathematics community!!!
When Director Li heard these words from Professor Qin, he picked up the manuscript again and looked through it carefully. As he read, he kept shouting, "Good! Good!"

No wonder he was so excited.

These days, the country is in a state of disrepair and needs to produce results urgently to encourage the vast number of workers and scientific researchers.

And "solving a world-class mathematical problem" will become the brightest satellite.

To be honest, the meaning of the geometric conjecture proved by Li Aiguo and the "1+2" ​​proved by Chen Zihua later are almost the same.

Director Li finally calmed down from his excitement and looked at Li Aiguo with admiration in his eyes: "Brother Li, you have quietly created such a big thing. This is the best gift you can give me."

After thinking for a while, Director Li asked Professor Qin: "What do you mean by pointing out that verification is still needed?"

Professor Qin said: "We have used the method of proof to obtain the specific number of tiles. As long as it is consistent with the number obtained by the calculation team, it can be proved that the proof process is correct and Li Aiguo's theory is indeed valid."

Director Li nodded: "This is a good idea."

He looked at Li Aiguo again: "But isn't this Li Aiguo style a bit too much?"

Although Director Li did not say it explicitly, Li Aiguo knew what he meant: if you add the word "rogue" to "Li Aiguo", it becomes a negative word.

Li Aiguo explained: "Flow refers to a phenomenon or process related to the flow of liquid, which involves fluid dynamics. It is a professional term."

Director Li nodded: "It's a professional term. I suddenly feel that this term has an academic flavor."

Li Aiguo: "."

After reporting their work, Li Aiguo and Professor Qin were about to leave when Director Li suddenly stopped them again.

"It just so happens that Secretary Liang returned from the capital the day before yesterday. Who among you would like to go with me to announce the good news?"

Professor Qin smiled and said, "Aiguo, you want us to go together?"

Li Aiguo shook his head: "The results have not been verified yet. Lao Qin, you are from the Ninth Bureau, you can go alone to explain the situation."

Li Aiguo's meaning was very clear, he wanted Professor Qin to go alone to show his face in front of Secretary Liang.

The honor of Factory 221 is of no use to Li Aiguo, and there is no need to steal Professor Qin's limelight.

What's more, I still have to show up at the final check time.

In addition, Li Aiguo had another meaning. However, he felt that an old scholar like Professor Qin would not be able to understand it, so he did not bring it up.

Professor Qin sensed Li Aiguo's good intentions and nodded knowingly: "Aiguo is cautious in his work. Don't worry, I know how to report it."

Director Li took Professor Qin to see Director Liang, while Li Aiguo took the two professors and Zhou Xiaomeng back to the office.

He wanted to compile these drafts into a formal mathematical paper as soon as possible.

In Secretary Liang's office, after listening to the report, he picked up the draft and took a look at it as usual, with a happy look on his face: "Great! If we can really solve this difficult math problem, then the pressure on our 221 Factory will be reduced a lot."

There were no outsiders here, and Secretary Liang did not hide anything. Director Li knew what he meant.

Since its establishment, Factory 221 has invested countless funds, manpower and material resources.

All we have obtained so far are a few equations, and there is not even a shadow of the big mushroom.

Some comrades have begun to question whether the existence of Factory 221 is really meaningful.

Professor Qin said modestly: "I just cooperated with Comrade Li Aiguo's work. The main ideas and important tools of the proof, the Li Aiguo School, were all proposed by Comrade Li Ai."

Secretary Liang knows the relationship between Li Aiguo and the Ninth Bureau.

He had been in Beijing a while ago to coordinate and resolve various issues that occurred in the Ninth Bureau.

He also knew Li Aiguo's position and the role he played in those matters.

Secretary Liang had a vague guess about Li Aiguo's identity and situation, but Professor Qin, on the other hand, wanted to praise him more.

Praising Professor Qin is equivalent to praising the Ninth Bureau and Factory 221. This is not a competition for credit, but a strategy.

"Don't be so modest. Comrade Li Aiguo's choice of you as his deputy has already proven your ability. In addition, you are also the one who coordinates the affairs of the group."

This is true. Although Li Aiguo has ideas and the Li Aiguo school, he does not have a detailed proof process.

Professor Qin is a graduate of a professional school and can also mobilize two professors of topology. Without Professor Qin's help, even if Li Aiguo came up with the proof, it would be full of loopholes.

This is what we often say, "Even if you are made of iron, you can only hammer a few nails."

In particular, the Ninth Bureau and Factory 221 are in urgent need of this honor.

Professor Qin was an old-fashioned professor. When he heard this, he felt that someone was stealing the credit and was about to wave his hand.

Director Li also saw Secretary Liang's intention at this time, and interjected: "Comrade Aiguo asked you to come here to report on the situation on his behalf. This shows his trust in you and in our Ninth Bureau."

Professor Qin then realized that everyone had reached a consensus and he was the only one who was still in the dark.

Why are there so many tricks? This seems to be more difficult than solving a math problem. Professor Qin complained in his heart, and a smile appeared on his face: "Secretary Liang, don't worry, I will cooperate with Comrade Li Aiguo and try to finalize the proof as soon as possible."

While Professor Qin was accepting Secretary Liang's praise, Li Aiguo had almost completed his thesis.

He also wrote a Russian version.

As for the English version, he is still at the level of CET-4 and does not dare to start easily.

"Comrade Zhou Xiaomeng, I heard that your parents are professors. How is your English?"

"It's OK." Zhou Xiaomeng poured a glass of water for Li Aiguo and asked curiously, "Why do you ask this?"

Li Aiguo repeated his idea: "Now I need a high-quality English version of the paper. Can you do it?"

"Let me translate the paper?" Zhou Xiaomeng was a little excited and nodded heavily: "Don't worry, I will definitely try my best."

People of this generation have a characteristic: if they say it, they will definitely do it.

After hearing Zhou Xiaomeng's statement, Li Aiguo understood her true English level and gave the task to her.

In the following two days, the two collaborated to write the English version of the paper.

On the morning of the third day, Li Aiguo woke up and quickly changed his clothes and washed up. He rushed to the computer room without even having breakfast.

At this time, Director Li, Secretary Liang, Professor Qin and Zhou Xiaomeng were already waiting outside the computer room.

Seeing Li Aiguo coming over, Professor Qin waved and said, "Old Zhou and his team have been working all night. They are probably at the last few steps. The results will be out in a few minutes."

Li Aiguo peeked inside through the glass.

Suddenly, all those researchers turned into Panda Warriors, with heavy bags under their eyes, cigarettes in their mouths, and their fingers operating on calculators at a rapid speed.

A moment later, laughter was heard from the computing room.

"Finally I figured it out!"

"Quick, take the calculation results to Director Li."

Professor Zhou pushed open the door, holding a document in his hand. Seeing Director Li and Secretary Liang were there, he felt a little strange: "Secretary Liang, Director Li, why are you here?"

Director Li did not explain and asked directly: "How many tiles are there?"

Professor Zhou handed the result to Director Li and said, "32 pieces. We have done two rounds of calculations and the result is 32 pieces each time."

Director Li was overjoyed when he heard this. He held the calculation result and said excitedly: "Good, good, it's really great."

Secretary Liang also waved his fist tightly: "We are going to make a great contribution this time."

Professor Zhou and those researchers were a little confused at this moment.

Just now they thought that the two leaders were excited about the calculation results.

But it doesn't seem like it. After all, the calculation result is just a step in the normal procedure and cannot be called a great achievement at all.

On the contrary, because the calculation results are different from the Russian data, it may cause controversy.

Professor Zhou saw that Professor Qin was also there, so he turned to look at Professor Qin and said, "Old Qin, what's going on?"

Professor Qin pointed at Li Aiguo and said, "Old Zhou, you may not know that Comrade Aiguo has proved the geometric conjecture. Based on this proof, we have proved the value of 32 pieces."

"By geometrization conjecture, are you referring to the three-dimensional special case of the Poincare conjecture?" Although Professor Zhou is not an expert in topology, he has some knowledge of these world-class mathematical problems and instantly understood what Professor Qin meant.

Professor Qin nodded heavily: "It is the Poincare conjecture."

The words fell.

There was silence.

Those researchers all looked at Li Aiguo.

Isn't it said that tiles can be calculated?
How did a world-class mathematical problem suddenly get proved?

No, don't get excited, this is not their achievement.

Trying hard to suppress their excitement, the researchers could no longer hold back their tears when they saw Director Li and Secretary Liang patting Li Aiguo's shoulders heavily.

Li Aiguo is their comrade and a member of the Southeast University community!
He has achieved results, and mathematicians from the University of Tokyo can also hold their heads high in the international arena.

What is comradeship?

That’s it!

What to do now? Go up and lift it high.

Li Aiguo was lifted high by the researchers, and cheers echoed throughout the entire ninth inning.

The smiling faces, set against the morning light, emit a fiery red glow, which is the light of faith.

With this great news, Director Li and Secretary Liang discussed it and announced in public: "Office 1 of the Ninth Bureau will have a day off. Everyone should relax and come to the celebration banquet in the evening."

After receiving the notice, the third company commander used all the food that had been accumulated over the past few days, cooked more than a dozen dishes, and served local barley wine.

While eating, everyone was in high spirits. After all, they had now solved the world's problem and determined the number of tiles, and were one step closer to creating giant mushrooms.

Director Li talked a lot with Li Aiguo.

When talking about how to proceed with a part of the Poincare conjecture, Li Aiguo suddenly asked: "Director Li, I am now also a member of the Ninth Bureau. I don't want to think about the salary. Should I get a subsidy?"

This made Director Li stunned for a moment, but he soon understood: "Are you going to publish this paper as a researcher of the First Office of the Ninth Bureau?"

Li Aiguo picked up the wine glass and took a sip: "This is the credit of Professor Qin and his team. Besides, I came up with this in the ninth inning."

As soon as these words were spoken, Director Li's eyes lit up.

He was originally thinking about how to persuade Li Aiguo to register him under the name of Jiujiu, but he didn't expect that this kid would take the initiative to propose it.

Director Li held Li Aiguo's hand tightly and said, "Brother Li, you are indeed my brother."

"My dear brother." Li Aiguo took the opportunity to climb up.

Director Li: “.”

At this time, Secretary Liang lit a cigarette and thought for a moment: "Should we put the name of Aiguo under Xiaohua's name?"

Xiao Hua? ? Li Aiguo was stunned for a moment before he realized that Secretary Liang was referring to Mr. Hua. With Secretary Liang's age and qualifications, there was no problem at all in calling Mr. Hua Xiao Hua.

Director Li nodded: "Office 1 of the Ninth Bureau is part of the Institute of Computational Mathematics of the Academy of Sciences. It is a bit sensitive to speak in the name of the Ninth Bureau. The Institute of Computational Mathematics of the Academy of Sciences is indeed the best choice. Let me contact Director Hua right away."

After the dinner, Director Li personally called Director Hua who was far away in Beijing.

After learning that a researcher in the first room of the ninth bureau had proved the geometrization conjecture, Director Hua only said one sentence on the phone: "Director Li, I need to see the entire proof process as soon as possible, as well as the researcher who proved this difficult problem."

Director Hua was already a mathematics giant in the country at that time. Being valued so much, Director Li realized that this proof might be more important than he thought.

"Don't worry, I will get my patriotic comrades back to the capital as soon as possible."

After hanging up the phone, Director Hua muttered quietly: "Aiguo. This name seems familiar. Two years ago, the Railway Research Institute and the Mathematics Institute cooperated, and the person in charge seemed to be called Aiguo."

Director Hua muttered a few words and shook his head: "The name Aiguo is too common. It may just be a coincidence."

Director Hua sat down again and took out a notebook from the drawer. This notebook contained the contact addresses of some foreign mathematics giants.

"If the proof is correct, the Institute of Computational Mathematics may become famous in the international mathematics community."

After Director Li hung up the phone, he immediately contacted the airport.

It just so happens that a transport plane carrying supplies will arrive at Factory 221 tomorrow, and Station Master Liu at the airport agreed to reserve a seat.

However, when he sent someone to notify Li Aiguo, there was no one in the tent.

Where did Li Aiguo go?
At this moment, he was invited by Liu Xingnian, the captain of the fishing team of Factory 221, to go to the fishing team to receive the benefit exclusively for the researchers of the First Office of the Ninth Bureau - Huangyu.

"Patriotic comrades, the湟鱼 here is unique in the world and tastes delicious." Liu Xingnian seemed very excited while driving the jeep along the way.

It was Li Aiguo who came up with the idea of ​​establishing the fishing team. Now that the fishing team has built two motorboats, Liu Xingnian wants to report the results.

Li Aiguo is more concerned about the ten fish that belong to him.

If I bring it back to Beijing, I won’t have to buy fish during the New Year.

“Where are the fish?”

"In the lake."

Li Aiguo: "."

****
It was not until the jeep arrived at the fishing team's base that Li Aiguo understood what Liu Xingnian meant.

The fishing team built dozens of shacks at the mouth of the river where it flows into the lake for the team members to live in.

At this time, the cold wind was howling, sand and stones were flying, and dozens of fishing team members gathered in front of the shack, preparing for the last winter fishing activity before the New Year.

"I've invited Commissioner Li here today. Let's not embarrass our fishing team! Let's go!"

Liu Xingnian has a cheerful personality. With a wave of his hand, the members of the fishing team set off in neat steps, shouting slogans, just like regular troops.

Li Aiguo saw Chen Daping and Liu Hong in the team.

Liu Hong had already changed into the same blue and black work clothes as the other members of the fishing team, with her hair tied up behind her head.

The whole person has less of the refined aura of an intellectual and more of a worker's flavor.

The two also saw Li Aiguo, and a strange look flashed in their eyes. They turned their heads and walked towards the lake.

Li Aiguo followed the team and handed Liu Xingnian a cigarette: "Captain Liu, what's going on with Chen Daping and Liu Hong?"

Liu Xingnian knew about the loss of the confidential package at Factory 221 a while ago, and said with a smile: "The two of them were assigned to the fishing team. According to the regulations, Chen Daping, as a worker, had to join the fishing team to go fishing. Liu Hong was a female comrade, so she only had to do some logistical work such as washing clothes and cooking, but Liu Hong insisted on going out to fish."

"How is the performance?"

"They performed very well." Liu Xingnian took a puff of cigarette and seemed to remember something: "By the way, they are getting married today."

"marry?"

After listening to Liu Xingnian's explanation, Li Aiguo finally understood what was going on.

Since Chen Daping and Liu Hong came to the fishing team, they have been very active.

Liu Xingnian, on behalf of the team, had a talk with the two and asked them to relax and reform themselves.

Just a few days ago, the two suddenly applied for marriage. Although Liu Xingnian was a little surprised, he still submitted their marriage application to the bureau in accordance with the regulations.

Although the two had made mistakes, they were comrades who could be reformed, so the bureau quickly approved their marriage.

"The team has allocated a shack for the two of them." Liu Xingnian pointed to the dilapidated shack in the distance and said, "Because the two of them made mistakes, some team members don't want to be associated with them, so they don't plan to hold the ceremony."

When Li Aiguo heard this, he nodded slightly and said nothing more.

According to the fishing plan, the team members will drive a motorboat to the river mouth, use a block net to enclose an area of ​​water at the lakeside, and then use a winch to pull up the net. One net can catch hundreds of kilograms of fish.

The fishing operation officially began, and the team members encountered trouble when the sailboat was undocking.

The dock was smeared with butter and the anchor was lowered into the lake, but no matter how hard everyone pushed the capstan or pulled the hull, the boat remained motionless on the dock.

Time passed little by little, and the fishing work was about to be delayed. Li Aiguo could not help but shouted, "Bring the rope, and follow me if you are not afraid of death!"

He first tied the rope around his clothes, then took off his cotton jacket and jumped into the freezing cold lake water with a splash.

The fishing team members and Liu Xingnian present understood Li Aiguo's intention, took off their cotton jackets and jumped into the lake.

Li Aiguo picked up the rope and was about to shout slogans when he saw Liu Hong also jumped down. He shouted loudly: "Even female comrades have jumped down. Don't learn from the coward later."

"Don't worry!" the team members shouted in unison.

"preparation!"

"pull!"

Following Li Aiguo's order, everyone pulled the boat into the lake together with ropes, and a miracle happened: the boat started to move.

"come on, come on, come on!"

Uniform slogans rang out, and the boat was pulled little by little and slowly entered the lake.

The players raised their fists and shouted happily: "Victory! We won!"

Li Aiguo was in good health, so nothing happened to him. However, Liu Hong's face had turned blue from the cold.

She climbed onto the shore, shivering in the cold wind.

Li Aiguo walked over and said, "Comrade Liu Hong, why don't you go back and change your clothes first?"

"No need, I can hold on." Liu Hong wrung the water out of her hair, turned around and rushed onto the boat against the cold wind.

The team members nearby were moved when they saw Liu Hong's expression. They also gathered their strength and picked up the fishing nets.

The entire fishing activity lasted until the evening, and nearly five thousand kilograms of Huangyu were harvested.

As it was getting dark, Liu Xingnian announced that the work was over. The team members parked the motorboat on the shore and then used a cart to push the Huangyu into a warehouse not far away.

The weather is cold this season, so there is no need to worry about the fish rotting. These fish will be delivered to Factory 221 tomorrow.

"Aiguo, this is the reward for your labor." Liu Xingnian strung together ten fat湟鱼 with a hemp rope and handed them to Li Aiguo.

After Li Aiguo took the fish, he did not get into the jeep, but walked towards the shack not far away.

The shack is very low and you need to lower your head to enter.
A kerosene lamp was lit inside, and with the dim light, Li Aiguo gradually saw the situation inside.

There was a wooden bed in the shack, and an iron thermos was placed on two lame benches.

Liu Hong and Chen Daping held enamel pots and ate steamed barley bread with hot water. The mud spots on their work cloth clothes had long since formed hard scabs.

In the whole house, there was only a "囍" character on the wall, indicating that today was the couple's wedding day.

When Li Aiguo came in carrying the湟鱼, he saw the newlyweds standing up in panic.

"Commissioner Li, you, you are here," Liu Hong said with a somewhat nervous tone.

Chen Daping's dark face flushed red, and he suddenly straightened his back and saluted: "Report to the Commissioner! We promise to supervise and reform each other in life and never cause trouble to the organization!"

Li Aiguo smiled and handed over the fish: "I didn't know you were getting married, so I didn't prepare any gifts in advance. This is a gift for you, congratulations on your wedding."

"No, no, no, we can't accept it!" Liu Hong waved his hands quickly, took a step back and said, "You have already helped a lot when dealing with our problems."

"The combination of intellectuals and poor peasants is in line with the organization's policy." Li Aiguo put the fish on the ground: "Comrade Liu Hong, Comrade Chen Daping, since we are all comrades, it means that we are comrades of the same class."

The meaning of this statement is very clear: Although you have made mistakes, you have not been deprived of the title of comrade, so do not have any psychological burden and do not belittle yourself.

Liu Hong had been under a lot of pressure since she made the mistake. When she heard these words, she was so moved that her eyes were filled with tears.

Chen Daping's eyes were also a little sore. He took a deep breath and bowed heavily to Li Aiguo: "Commissioner Li, don't worry, we will definitely reform ourselves through labor."

Li Aiguo chatted with the two of them and found out why they got back together.

Liu Hong handed Li Aiguo a cigarette and said, "After the confidentiality package incident, I realized the mistakes in my thinking.

I should not regard myself as an intellectual, and I should not deceive my comrades for the sake of face.

After coming to the fishing team and working for a few days, I realized that I should become a brave person and break the shackles of my family. So I took the initiative to propose to Comrade Chen Daping. "

Li Aiguo: "Take the initiative to propose. Comrade Liu Hong, your courage is worthy of admiration."

Then he turned to look at Chen Daping: "Old Chen, how did Comrade Liu Hong propose to you?"

Chen Daping blushed: "She took a kitchen knife and put it on my neck."

Li Aiguo: "."

At this time, footsteps were heard outside, and then Captain Liu Xingnian walked in.

"Comrade Chen Daping, Comrade Liu Hong, on behalf of the fishing team, I congratulate you on your marriage."

"Captain, you're welcome."

Liu Xingnian said: "Come out for a moment."

Liu Hong and Chen Daping didn't understand what he meant. They looked at each other, stood up and left the shack.

A bonfire was lit in the open space outside, with a grilled fish on it, and dozens of members of the fishing team were holding various gifts in their hands.

"Mr. Chen, Xiao Liu, happy wedding."

"You are the first newlywed couple in our fishing team. You must set a good example and have a baby soon."

"Hit the wave, hit the wave!"

Amidst the laughter, Liu Hong and Chen Daping felt as if they had found home.

The oil lamp cast the shadows of everyone through the window onto the newspaper-covered wall.

The lead typeface of the headline "Intellectuals should take the path of integrating themselves with workers and peasants" was reflected on the bottom edge of the word "happiness".
