The passionate years starting from the college entrance examination

Chapter 347, Stealth Fighter (please vote for me)

In February 1969, Mariner 6 was successfully launched.

Chen Guohua was sitting in his office, looking at the report in the Boston Globe, feeling very uncomfortable.

Mariner 6 is North America's Mars probe. It has been launched now and will successfully approach Mars in the future.

However, at present, neither Moscow nor the mainland seems to be very optimistic about Mariner Six.

Just because the space vehicles launched by North America seem to have good and bad times, it may not be completely possible.

Regarding this situation, Chen Guohua was unable to complain, so he had to pick up the phone and call Qiu Zongyue, urging the latter, when can the space station project be restarted?
"Guohua, the leaders are still discussing and consulting Dean Qian for their opinions. We still need to wait."

After hearing these excuses, Chen Guohua's heart sank.

In fact, he had already been mentally prepared before making the call, so Chen Guohua was not very disappointed when he heard Qiu Zongyue's words.

There is a saying that you won’t shed tears until you see the coffin, and that’s what Qiu Zongyue and the others are talking about.

It is estimated that Qian Xuesen, Sun Jiadong and others are still like gamblers, they have paid too many sunk costs and are unwilling to admit defeat.

Especially after knowing that North America had successfully launched the Saturn V and achieved the first human flight around the moon, Qian Xuesen and the others worked even harder and worked overtime to follow up and not fall too far behind.

But is this possible?
North America has strong financial resources. The North American Aerospace Industry Agency can simultaneously advance the two projects of the Apollo moon landing program and Mars exploration at a very fast speed. The technological breakthroughs are even more overwhelming, without difficulty at all.

Others are like divine help, but what about ourselves?

There is a fart helper!

It's already pretty good without being held back. What else do you want?
After hanging up the phone, Chen Guohua shook his head and laughed, then stood up and left the office.

In the aerospace engine laboratory, Chen Guohua walked in after changing into protective clothing.

In this laboratory, several aircraft were born, and those aircraft are now soaring in the blue sky, guarding the airspace of the motherland.

Today, the project being researched is the engine of the stealth fighter.

This project was established last year only after Chen Guohua took the time to complete the civil aviation passenger aircraft project.

In fact, not only him, but also leaders like Qiu Zongyue also hoped that the stealth fighter project could be established earlier, but Chen Guohua himself was too busy.

"Director Chen, can you now talk about the technical points of the stealth fighter? Why do I feel that the engine of our stealth fighter is very ordinary?"

In the laboratory, Dai Xizhang stood aside and looked at Shen Zhiyang who was speaking with a smile, but he himself did not make any comments.

Shen Zhiyang's words represent the thoughts of most researchers in the entire aerospace engine laboratory.

In the past period of time, since the establishment of the project, Chen Guohua only provided some technical information to let them first understand the related technologies of stealth fighters.

"Are you sure it's ordinary?"

When Chen Guohua heard this, he immediately smiled, but there was disappointment in his smile.

The group of researchers in front of them are still a little behind after all. From the technical data, they have not found any difference between stealth fighters and ordinary fighter jets.

You must know that they are the research and development team of the Yaoyao-9 fighter jet, as well as the research and development team of bombers and civil aviation aircraft. It can be said that they are extremely experienced.

However, Chen Guohua had handed over the relevant technical information on the power system of the stealth fighter to Dai Xizhang and the others last year, but now he was told that there was no difference? very common?
It was just a joke. They didn't seem to notice what special materials were added to the stealth fighter's engine.

"Director Chen, I think there is a difference, but I can't tell the difference, and I don't understand why it's so superfluous."

Suddenly, Shi Jiayi said:
"I have read the technical information on the engine of the stealth fighter, and I have read it more than once, but I still don't understand why the engine is designed like this? We can just avoid enemy radar detection. This can be used This can be achieved through the aircraft coating materials and special fuselage design you mentioned before.”

"But the design of the engine is a bit redundant in my opinion, and it sacrifices a lot of speed and increases fuel consumption. This does not meet the relevant requirements of the leaders on the development of fighter technology."

After hearing Shi Jiayi's words, Chen Guohua still kept smiling, looked at the others and said:

"Xiao Fan, Xiao Shao, Xiao Lin. What do you think?"

At the beginning, in 1960, Dai Xizhang, director of the Ninth Research Institute in Beijing, sent eight people, Shi Jiayi, Fan Zhilun, Shen Zhiyang, Shao Fuqi, Lin Kangmin, Liu Xuetian, Gao Wen, and Xu Kangtai, to the Zhenhua Research Institute. work.

After so many years of hard work, the eight of them have already become experts in the aviation industry, and have conducted in-depth research in the research and development of aerospace engines and other aspects.

But no matter how powerful they are, their vision and knowledge still have great limitations of the times.

Liu Xuetian and others who were named expressed their opinions. Except for Lin Kangmin and Gao Wen, no one else found the advantages of the engine.

What Lin Kangmin means is that the engine of the stealth fighter can reduce noise. Regarding this, there is no doubt that it greatly reduces the possibility of enemy detection.

Gao Wen's observation is focused on the design of the engine itself. He does not feel that there is no big difference between the engines of stealth fighter jets and the Yaoyao-9 fighter jet. On the contrary, he said that there is still a big difference.

The most important point is that in terms of cost, the cost of stealth fighter engines is definitely higher.

"Yes, Comrades Gao Wen and Lin Kangmin paid close attention to the details and really got to the point."

Hearing Chen Guohua's praise, Lin Kangmin and Gao Wen burst into laughter. On the contrary, Shen Zhiyang and Shao Fuqi were a little reluctant.

If you just count these small differences, it's really meaningless. They also know these points.

No matter what they thought, Chen Guohua was too lazy to pay attention to this.

"Let me tell you why the engine we are designing now has so many special features, and what are its special key points."

In the following time, Chen Guohua conducted a comprehensive technical analysis on the power system of the stealth fighter from the design level.

As the world's first stealth fighter research and development project, Chen Guohua's right to speak on stealth fighters has the highest authority, and there is no doubt about it.

As the power system of the stealth fighter is also one of its advantages, all aspects must be considered at the beginning of the design.

Chen Guohua mainly referred to the two stealth fighter jets, the J-35 and F35, and then combined their advantages to carry out a localized and low-cost comprehensive design.

The first is the power system. Chen Guohua made technical improvements based on the Pratt & Whitney F135 afterburning turbofan engine, allowing this engine to maintain high reliability while maintaining high thrust, low heat characteristics and low noise. , advanced combustion chamber technology and excellent fuel efficiency.

Not to mention other things, Chen Guohua feels that he has achieved the ultimate in reducing fuel consumption.

After all, the core competitiveness of a stealth fighter is not its supersonic flight speed, but its stealth performance.

Even so, on the premise of ensuring these performances, Chen Guohua has designed a variety of advanced materials and processes for this engine, which is enough to ensure that this power system can provide powerful power output for the stealth fighter, allowing this fighter to maintain excellent maneuverability It has advantages in performance, long-range combat capabilities and supersonic cruise.

The most important point is that Chen Guohua designed it in a modular manner, which facilitates maintenance and upgrades, and also brings great convenience to the reliability and maintenance performance of the fighter jet.

Researchers like Lin Kangmin, Shi Jiayi, and Fan Zhilun were like listening to a book from heaven.

Obviously those technical and design materials have been scanned by them many times, and the design drawings have been engraved in the depths of their minds. In the end, they are as blind as if they didn't see these advantages?

Ultra-low fuel consumption, excellent maneuverability and long-range combat capabilities, as well as the core features, low heat characteristics and low noise, these are the most awesome features.

Because powerful stealth performance is the core competitiveness of stealth fighters.

"Director, why haven't we discovered these advantages?"

Gawain was dumbfounded. He didn't expect that there were such twists and turns.

"That's because you haven't thought about why I designed it like this in the first place. You just think this is a task, just a job, and it has nothing to do with you. You think that with me as the leader of the project, you just think Just concentrate on your work, and I’ll take care of the other brain-burning things, right?”

Looking at Gao Wen, Lin Kangmin, Shi Jiayi and others, Chen Guohua shook his head and said:

"Since the earliest drones we designed and developed, you have become dependent on me. I know this is wrong, but the project was initiated by me, and I must be responsible for this project."

"Furthermore, the leaders above are urging me urgently, so I have no choice but to act like this."

After a pause, Chen Guohua continued:
"Okay, the advantages of the stealth fighter's power system are probably these. How to implement them specifically requires your help, so in the days to come, please don't lose track."

"Stop deserting, let's start analyzing the technical details."

The Pratt & Whitney F135 afterburning turbofan engine is a high-performance turbofan engine developed for the Lockheed Martin Lightning fighter jet.

There are two models, one is a conventional take-off and landing type, and the other is a short take-off and vertical landing type, which was originally developed on the basis of the Pratt & Whitney F119.

So it has low observability, advanced thermal management and integrated control systems. Even in later time and space, it was one of the most advanced fighter engines at the time.

So today in 1969, this engine is even more advanced. Once developed, it can be said to be a ghost-like existence, guaranteed to cause headaches to enemy fighters and reconnaissance aircraft.

"Everyone should pay attention to one thing. I have made designs and technologies in these aspects to reduce the infrared and radar signals of fighter engines."

In the conference room of the laboratory, the table is filled with various technical materials. It is Chen Guohua's class time to explain the technical details to everyone.

Related technologies such as vector nozzle technology and gallium nitride radar technology applied to the J-35 were all selectively deleted and added by Chen Guohua, and finally integrated into the current stealth fighter.

Of course, the current power system of Chen Guohua's fighter jet has a stealth nozzle that uses traditional sprayers and flame holders instead of curved blades coated with ceramic radar absorbing materials and rear-mounted fuel injectors.

In this way, this stealth fighter blocks radar scattering at the turbine and improves rearward stealth performance while ensuring flight capabilities. At the same time, the tail nozzle is designed with fifteen overlapping serrated trailing edge panels, further Reduce wake infrared signature.

"The stealth effect of such a design can reach ceiling levels. Even if Moscow or Washington can develop the same type of stealth fighter, they will only be able to eat dust behind our stealth fighter and be beaten by us."

"The most important thing is that it is cheaper and easier to maintain."

When Chen Guohua explained these technical details, Shi Jiayi and Lin Kangmin nodded from time to time, seemingly understanding, but in fact who knew?

It took them several months to become familiar with these technical information, but for such a large and complex engine, it is not easy to be completely familiar with all the technologies.

After spending nearly a week, Chen Guohua finally explained the technical details to them, and he was really relieved.

"Okay, everyone, get off work and go back and take a good vacation. When we come back next week, we will start the research and development process immediately. Everyone must make sure that their brains are awake, so as not to cause any trouble or delay the progress of the project."

"Thank you, director."

Lin Kangmin and the others all stood up and said in unison.

When he returned to the director's office, Qiu Zongyue had been sitting there waiting for a while.

"Guohua, thank you for your hard work. I heard that you have been busy developing the power system of the stealth fighter recently. Is there any problem with the overall progress of the project?"

After hearing Qiu Zongyue's words, Chen Guohua sat down, smiled and shook his head and said:

"There is no problem now. All the technical details have been sorted out. We will start the research and development process next Monday. At present, everything is within the project plan and there are no surprises."

"That's good!" Qiu Zongyue nodded slowly and then said:

"Let me tell you good news. There are currently three leaders who support restarting the space station project, but they have not agreed to cancel the moon landing plan. They mean to proceed simultaneously."

When Chen Guohua heard this, he immediately rolled his eyes and said:
"Leader, what kind of good news is this? If the two projects are promoted at the same time, we simply cannot support it with our financial resources."

Today's mainland is indeed much more affluent than in the original time and space, but in fact, there are many scientific research projects, and there are many more projects, and money is used everywhere.

If the space station project and the moon landing plan are promoted at the same time, it will definitely not work.

Let’s talk about the current field of scientific research first. The research and development of atomic bombs, hydrogen bombs and intercontinental missiles, which are artifacts of the country, have not stopped, but relatively speaking, the speed has slowed down a bit.

After all, they still need to develop weapons technology such as land-based launch silos, vehicle-mounted launches and airdrops, as well as related technology research and development work such as missile nuclear warheads and hydrogen bomb atomic bomb storage technology. These all require time, manpower and material resources to advance, and they will still Consume a lot of research funds.

The second is the moon landing plan. This plan has been advanced for several years, and satellite rockets are launched every year. These are commonly known as large fireworks.

Since it is fireworks, it is an extremely money-burning thing.

The third is the research and development of related auxiliary technologies and equipment by the Chinese Academy of Sciences and other scientific research institutions. It seems that each project requires a small amount of scientific research funds, but it cannot support the huge amount.

For example, some technology research and development projects submitted by BAIC manufacturing plants, steel plants and other related units, as well as some small technologies in Majuqiao Industrial Park and Baiyun City Industrial Park in the south, etc.

These are small technical projects that Zhenhua Research Institute does not like, or projects that are too busy, so they are left to other institutions such as the Chinese Academy of Sciences to complete.

Although Zhenhua Research Institute is very powerful, the number of people in this research institute is limited after all, and Chen Guohua's time is also limited.

Therefore, if hundreds or even thousands of scientific research projects are gathered together, the scientific research funds they need to spend will be very scary.

Finally, there are the scientific research projects of Zhenhua Research Institute. If you count them in detail, there are too many.

Stealth fighter projects, high-speed rail projects, extreme ultraviolet lithography machine projects, etc., as well as projects in many laboratories such as biopharmaceutical laboratories and drone laboratories.

It can be said that the scientific research projects within Zhenhua Research Institute are not only numerous in number, but also very difficult, and the amount of scientific research funds required is even more jaw-dropping.

Take the extreme ultraviolet lithography machine project as an example. This is a scientific research project launched in January 1965. It consumes at least 100 million yuan in scientific research funds every year.

It's like swallowing gold, which is heartbreaking.

Moreover, not only the extreme ultraviolet lithography machine project, Zhang Jichuan and Zhao Jusheng have also set their sights on the quantum chip project.

Quantum chip is a super cutting-edge technology. Nowadays, it is a scientific research project that has not even perfected the theory. However, it turned out that it was targeted by a group of young super-scientific students from Peking University such as Zhao Jusheng, Lu Zijing, and Zhang Jichuan. .

If this project is really launched in the future, there is no doubt that this is another super gold-eating beast.

And the most critical thing is that quantum chips will be difficult to realize for a long time.

This is just like what Chen Guohua said to Xue Jinquan and Zhang Jichuan in 1965 before the establishment of the extreme ultraviolet lithography machine project: it is difficult to achieve extreme ultraviolet lithography machines in a short period of time.

As a result, Chen Guohua was right. Four years have passed since 1965, and it is now February 1969. As a result, the extreme ultraviolet lithography machine has still not been built.

Therefore, if we take a closer look at the current scientific research projects in the Mainland, we will see that there are quite a lot of money-burning projects, all of them are gold-eating beasts, and all of them are extremely difficult to maintain.

Once it is broken, it is bound to trigger a chain reaction.

Just scientific research projects have already eaten up so much funding, and other major projects involving people's livelihood, national defense, etc., such as the high-speed rail project personally initiated by Chen Guohua.

The high-speed rail project is not only a scientific research project, it is also part of the people's livelihood and national defense projects. The technical requirements for rebuilding a high-speed rail line from Beijing to Jincheng, which is just over 100 kilometers, are unprecedentedly high.

The previous railways had no fences, and pedestrians and animals could travel freely.

After all, the speed of trains in this era is only fifty or sixty yards. If they are not fast, you can avoid them.

But the high-speed rail is completely useless.

Fences must be built and trees must be planted to enclose the entire line to prevent any pedestrians or animals from crossing the railway.

Otherwise, it will not just be as simple as pedestrians or animals being hit. In severe cases, it may also lead to the destruction of high-speed rail trains and deaths.

Therefore, the amount of money spent to build such a high-speed rail project is astronomical.

In that time and space of later generations, the cost of building a high-speed train line was about 140 million yuan per kilometer.

A simple calculation of the differences in prices, labor costs, etc. between the 1960s and later generations shows that the cost of a high-speed rail project in this time and space is at least one million yuan per kilometer.

The distance from Beijing to Jincheng is about 136 kilometers. In other words, the investment in this high-speed rail line alone requires 13.6 billion yuan.

RMB 13.6 billion does not seem like much.

But in fact, this is just a high-speed rail line from Beijing to Jincheng. There are so many places across the country, especially the Qinghai-Tibet Plateau, Western Xinjiang and other places. That is the most difficult part of building high-speed rail lines.

In addition to the high-speed rail project, there are other train lines, as well as projects such as road and bridge construction, as well as the civil aviation passenger aircraft project, facial recognition and identity certification projects previously promoted by Chen Guohua. These are gold-eating beasts. If you simply count it in detail, it is already huge. It is impossible to calculate it in detail. Otherwise, it will be heartbreaking.

China Resources has a strong ability to make money. It can earn at least tens of billions of dollars every year and help many projects in the mainland.

But no matter how powerful China Resources is, there is only one company.

Even if there is still money for white-glove companies like Duoduo Supermarket, the money earned will be given priority to supply other projects.

In short, Chen Guohua strongly supports the restart of the space station project, but if it is promoted simultaneously with the moon landing plan, then he will definitely not agree.

"Why can't you support it?"

Qiu Zongyue was puzzled and said:
"Didn't you say that white-glove companies like Qianduoduo Supermarket will soon enter the fast lane of development? By then, we will be exporting more and more supermarket products."

"And this year is 1969. China Resources will also launch new technology products by then. It will definitely be able to earn more foreign exchange by then, right?"

When the other party mentioned the new electronic products of 1969, Chen Guohua couldn't help but shake his head.

In today's era, apart from mobile communication technology products that can make a lot of money, other electronic products are really difficult to make.

Unless the Internet in North America can suddenly develop rapidly, Chen Guohua doesn't know how to make big money.

But the Internet is like a double-edged sword. If it is placed in North America, it is likely to cause incredible things.

Chen Guohua's idea is to wait a little longer and then personally promote the development of the Internet after 70 years. For now, he will first popularize computers.

Three-digit computers did not make computers popularized much faster.

In fact, this kind of computer is more like a game console than a computer.

Because many people buy computers mostly for the games inside them.

In the eyes of future generations, card games are very boring, as if I am not the Cheng Yong in the God of Medicine. I stay in my own oil shop and play card games with a cigarette in my mouth all day long.

But in this era, it is a very advanced game. Not only can you play it for a whole day, but you can even play it for more than half a year or a year without feeling bored.

What's more, in addition to card games, there are also two games: Minesweeper and Ping Pong, and it can also be used for office work, which is very friendly especially for clerks.

So having a computer, for many people, is not just for work, but also a good thing for entertainment.

Therefore, in this era, there is no big difference whether it is promoted by the Internet or not.

On the contrary, the popularity of computers is not yet great, and it is not suitable to promote the popularity of the Internet. After all, this thing requires the laying of a fiber optic network, which is very, very expensive.

Optical fiber is quite expensive and the cost is high, but it is no worse than those signal transmitters.

Of course, the fiber optic technology in the mainland is now very developed and the cost has been reduced a lot.

Once mass production occurs, costs can continue to drop.

The Internet makes money, but Chen Guohua has not taken the initiative to promote its development, so the new electronic products launched this year may not be very profitable.

Seeing Chen Guohua shaking his head, Qiu Zongyue was about to say something, but the former had already given Qiu Zongyue a bunch of reasons.

How much money can you make?

The market expectations are there, so how can we possibly make much money?
"Isn't there a possibility that they might become very popular like the Huayue Walkman?"

When Chen Guohua heard this, he couldn't help but smiled bitterly and said:
"To be honest, leader, I also hope that our products will be as enthusiastically sought after by the market as the Huayue Walkman, but many things are not what we want."

“Now that economic globalization is accelerating, there will be more and more wealthy people, but electronic products must first be low-priced before they can become universal in the market.”

"The highly sought-after Huayue Walkman is actually not a very cheap product. However, its appearance happened to fill this part of the market gap. Coupled with a series of coincidences such as the hype of foreign media, it caused great excitement. Big sensation”

“This kind of marketing coincidence is rare but not sought after”

Qiu Zongyue nodded thoughtfully and then asked:

"Guohua, your marketing planning skills are also very strong, why don't you give it a try?"

"Leader, this is really difficult, and it requires a lot of investment. What if it all goes to waste?"

In fact, Chen Guohua is not afraid of wasting his time, but he doesn't have much time to focus on these things.

Maybe Qiu Zongyue himself didn't realize that what Chen Guohua is doing now is a concession for the next space station project.

In Chen Guohua's estimation, not only this month but also next month, the space station project will be strongly restarted, and the moon landing plan will be abandoned.

Just because the situation in foreign countries is now very obvious, the strong rise of the North American Aerospace Industry Agency has become unstoppable.

Even Moscow can’t catch up, let alone the mainland?
Now that on the track of moon landing, North America can already fly around the moon, but the mainland is not yet able to send an unmanned test spacecraft into a lunar orbit.

The gap between them is too big.

Either this year or next year, North America will officially land on the moon.

But whether the mainland can successfully send an unmanned test spacecraft into lunar orbit this year remains to be seen.

Based on this, the wisest choice is for the mainland to abandon the moon landing plan and restart the space station project.

Chen Guohua can already predict these things, so he must seize the time to deal with other projects to make time for the next space station project.

Of course, as long as there is an opportunity for China Resources to earn more foreign exchange, Chen Guohua will take time to help no matter how busy he is.

But it was obvious that Chen Guohua did not have much confidence in the new product he had developed, so he rejected Qiu Zongyue's request.

Seeing that Chen Guohua said this, Qiu Zongyue had no choice but to nod and accept.

Anyway, he was just expressing his own opinion, and it was more up to him to see if Chen Guohua accepted it.

Chen Guohua himself is the most professional and the one who best understands these market expectations and product performance. Not only Qiu Zongyue himself, but other leaders also need to listen to the former's opinions.

After handling the work matters, Chen Guohua dragged his tired body back home this time.

When the little cotton-padded jacket Chen Si saw her father, she had already rushed toward her father with a cute smile on her face.

"Dad, Dad, you are back"

Chen Guohua was also very happy when he saw the little guy, especially when there were two smaller kids behind him.

The two siblings, Chen Xi and Chen An, have turned three years old. They are now able to run, jump and are very active.

It is estimated that in a while, they will definitely be the main force chasing chickens and chasing dogs, and they will be extremely energetic.

Surrounded by three little guys, Chen Guohua was resurrected with full health and did not feel sleepy at all.

"Where is your eldest brother? Where has he gone?"

"I know, I know. My eldest brother is doing his homework. Mom said that the math questions you gave me, Dad, are too difficult. My eldest brother can't even do it."

Listening to the words of the little cotton-padded jacket Chen Si, Chen Guohua suddenly felt strange. Is the math question he asked difficult?

So at his urging, the three little guys took him into the house.

As soon as the father and daughter entered the house, Yu Moli inside could not help but frown and said:
"Brother Guohua, weren't the math questions you gave Weiwei too difficult? I didn't let him do it because I couldn't seem to do it myself."

"Let me see which question it is."

When Chen Guohua heard this, he stepped forward and said.

His eldest son Chen Wei is nine years old this year. He will be nine years old in July 2069.

Children of this age can definitely start to develop their thinking and logical abilities.

Of course, judging from past contacts, Chen Wei is not one of those top math geniuses. He has had excellent math talent since he was a child.

But he is not an ordinary child. At least Chen Wei has a certain talent in mathematics. There should be no problem in completing the questions he took out before to test mathematical logical thinking.

Opening the book, the printed-like fonts on it were actually not printed, but handwriting written by Chen Guohua himself.

"This is a question, right?"

After confirming which math problem it was, Chen Guohua suddenly smiled, then looked at Chen Weidao:
"Son, tell dad, have you thought about this question?"

A nine-year-old child has already learned to think independently, not to mention that Chen Guohua has been cultivating his eldest son's logical thinking ability in this area.

At the very least, he needs to complete one such question every day.

Just as Chen Wei was answering the question, two sisters, Chen Xiaomei and Chen Xiaomin, also walked in outside the room.

Chen Xiaomei, who was born in 1950, is already nineteen years old this year. As Chen Guohua predicted, she has not been admitted to college.

There is no way. In universities in this era, only a few science and engineering majors are still open to applications. Because of Chen Guohua's insistence and the leadership's insistence on scientific research projects, they have been retained.

But majors related to liberal arts have almost been wiped out.

Against this background, if Chen Xiaomei wanted to get into college, the difficulty level would be as high as the Eighteenth Level of Hell.

The extremely difficult college entrance examination is definitely the most difficult since the founding of the People's Republic of China.

After failing the college entrance examination, Chen Xiaomei went to the BAIC Manufacturing Plant to work as an ordinary leader under the arrangement of her superiors.

It is normal for a high school student to become a leader in this era.

BAIC Manufacturing Plant was originally the unit where Chen Guohua had been working before, and after Tian Jingye was restarted, he became more proactive in moving closer to Chen Guohua.

Although Chen Guohua repeatedly emphasized, he also declined all benefits from Tian Jingye.

But I couldn't stand it. Chen Xiaomei was at the BAIC manufacturing plant.

Therefore, after she was assigned to the BAIC Manufacturing Plant, she was quickly noticed by Tian Jingye, and then she was arranged by the latter in various ways. Then Chen Xiaomei quickly became a minor leader with great merit.

It was almost Tian Jingye who personally gave her the credit for her achievements and then promoted her.

Otherwise, it would be impossible for a high school graduate to become a leader so quickly.

Like her eldest sister, Chen Xiaomei was not in a hurry to get married. Even if her eldest sister-in-law helped her arrange a blind date, she refused.

Regarding this, Chen Guohua didn't bother to talk to her. Anyway, if he didn't get married after turning twenty, he would definitely tie her up and ask her to seize the time to resolve her marriage issues.

No more than twenty-four years old at the latest.

Perhaps in the past, Chen Guohua also felt that by not getting married so early, he could have a few more years of freedom.

But in this era, if you don't get married, you are a different kind of person.

Humans are social animals.

People who don't fit in with others are, after all, alien and different, and will be gossiped about.

Although being gossiped about is not a big deal, after all, people should not live in other people's mouths, but live their own lives.

But in this era, most people get married and have children, which is the mainstream of society.

Not to mention the task of carrying on the family line, having someone who can accompany you through the rest of your life is better than being alone, right?
Therefore, finding a suitable person and spending the rest of your life together is the norm in life.

After the two sisters walked in, they heard it was math teaching time and wanted to run away, but their sister-in-law called out to them.

So the two sisters could only sit down and listen.

Even the two little guys, Chen Xi and Chen An, who were three years old, were pressed into their seats by their mother and sat down obediently to listen to their father's lecture.

Chen Wei said that he had thought about this question, and Chen Guohua asked him to talk about his thoughts.

This math question is actually that a triangle plus a square equals five (△+□=5), a triangle plus a circle equals six (△+O=6), a square plus a circle equals seven (□+O=7), solve the triangle and square and circle respectively.

In fact, it is a standard three-dimensional linear equation. It seems very complicated, but it is actually very simple.

"Dad, I know how to solve it"

The little guy stared at the question for about a minute and suddenly said excitedly.

Yu Moli was surprised and asked, "So fast? Have you really solved it?"

"This is just a three-dimensional linear equation. Jasmine, you're not going to return all the math to the teacher, are you?"

Hearing Chen Guohua's words, Yu Moli gave him a roll of his eyes.

She said she couldn't figure it out, but could she really not figure it out?

It's just that she is a mother and is a little too protective, fearing that her son will be hit.

Chen Guohua has said a long time ago that it is best for children to think about all math problems by themselves rather than for adults to help solve them.

"Yeah, mom, I know."

The little guy nodded seriously, then took a pen to write and draw on the paper, and soon figured it out.

In fact, it is very simple, that is, add the first and second numbers, and it will become (2△+□+O=11).

而第三这里是（□+O=7），如此也就是说（2△+7=11），那么（2△=4），即（△=2）。

Then the triangle has been determined to be two. From the first point, we can calculate that the square is three and the circle is four.

"Awesome, Weiwei, you are great"

After Chen Wei solved the problem, Yu Moli was the first to praise it. Chen Si and the other three little kids also applauded, as did the two sisters Chen Xiaomei and Chen Xiaomin.

Even Chen Guohua also praised the little guy, and then said:

"Son, there are several other solutions to this question, do you know?"

For a child who has just entered third grade, linear equations in three variables are a bit difficult, but not bad.

Of course, other solutions are a bit difficult for Chen Wei to be honest.

No, after hearing what his father said, the little guy started thinking hard about this question.

Chen Si, the child, even had a grimace on his face, thinking that his father is terrible. Is there any other solution?

As for the two little kids, Chen Xi and Chen An, their eyes were wandering and they were obviously unable to sit still.
