The other side.

Li Donglai had already rode his bicycle to the courtyard of the coal factory outside Dongzhimen.

Zhang Daheng's daughter-in-law is a worker in a coal factory.

And his wife’s brother is still the leader of the coal factory.

When the houses were divided, two tube rooms were specially allocated to Zhang Daheng's wife.

The conditions here are much better than those in the Siheyuan.

The spacious courtyard is filled with various green plants. Even in winter, everything is green.

Li Donglai entered the courtyard and saw an old man exercising next to the equipment. He walked over and said hello and asked: "Uncle, do you know where Zhang Daheng's home is?"

The uncle jumped down from the horizontal bar, pointed to a tube building next to him and said: "Daheng's house is on the second floor, which is the living room on the east side. I saw him going downstairs to buy groceries just now. He should have already gone by now.

came back."

After thanking the enthusiastic old man, Li Donglai walked up the stairs to the second floor, knocked gently on the east door, and heard a voice coming from inside.

"Who is it?"

"I, Li Donglai." Li Donglai shouted at the top of his lungs.

After a while, the house door opened.

Wang Daheng poked his head out, and when he saw it was Li Donglai, he was so shocked that he couldn't close his mouth.

"Master, how did you come here?"

"When you moved, I was busy with a project and didn't attend your housewarming ceremony. What happened? Now that I'm here, you don't even invite me in."

Li Donglai raised the newspaper bag in his hand and said.

"Master, look at what you said. If it hadn't been for you, I wouldn't have the good life I have today. Am I the kind of person who is kind and ungrateful?"

After Wang Daheng said this, he opened the door and let Li Donglai into the house.

There is nothing wrong with what Wang Daheng just said.

A large part of the reason why Wang Daheng and his wife were able to get married was because of Li Donglai's intervention.

At that time, Wang Daheng and his wife had been dating for two years.

When it was time to meet his parents, his wife's family disliked Wang Daheng because the family was too poor.

And he also disliked that Wang Daheng was just a worker, not a leader.

By chance, Li Donglai met Wang Daheng and his wife talking dejectedly.

After learning about this incident, he personally acted as a matchmaker for Wang Daheng.

At that time, Li Donglai had already become famous in China, and even Wang Daheng's wife's family knew Li Donglai's identity.

After hearing what Li Dong said, Wang Daheng was a reliable person, so his wife's family agreed to their marriage.

After the two got married, Wang Daheng lived up to Li Donglai's expectations.

Although he is just a worker, he worked conscientiously in the workshop and was awarded the title of advanced worker last year.

If things continue like this, maybe within a few years he will be able to work instead of doing work and become the leader of the workshop.

And Wang Daheng is also very filial.

Every time something happened to his wife's family, Wang Daheng would help solve it.

His father-in-law always said that Wang Daheng was a good son-in-law when he saw him.

After Wang Daheng let Li Donglai into the house, he helped pour tea and said with a smile: "Xiaobai is working overtime today and won't be back until the evening. It will be noon soon, what kind of food do you want? I'll buy it now."

Li Donglai waved his hand and said, "No need, I came to you today because I have something to discuss with you."

"Looking at what you said, if there is anything you can just give me an order, there is no need to discuss it." Wang Daheng said embarrassedly.

Li Donglai said: "This matter is actually none of my business. Yan Jiecheng and Xiaodang in our compound are married. You should also know about this matter. Now these two people have no house to live in. So, I want to buy you

The family stayed in the house in the courtyard."

Hearing this, Wang Daheng said with a smile: "My house is dilapidated and dilapidated. I don't live in it anyway. My father has wanted to sell it for a long time. You can just look at it and pay some money for it."

"That's what you said. Although those two houses are dilapidated, they can still be lived in. I will only be a puller this time. The specific price will be discussed between you and Yan Jiecheng." Of course, Li Donglai will not give everything.

After all, this kind of thing involves money.

If Wang Daheng deliberately asked for less money for his own sake, wouldn't he suffer a loss?

Li Donglai doesn't like to let honest people suffer.

Wang Daheng was also aware of Li Donglai's temperament, so he nodded and said, "Master, don't worry, I won't open my mouth like a lion."

The matter was almost discussed, and Li Donglai helped him make an appointment to meet Yan Jiecheng, then rode his bicycle back to the laboratory.

As soon as Li Donglai sat down in the office, Zhang Qingcui knocked on the door.

"Director Li, there are no new projects in our steel rolling mill laboratory for a while, and the researchers are already anxious."

Li Donglai said: "I just happened to be preparing to launch a project. You should call all the researchers for a meeting now."

Upon hearing the news, Zhang Qingcui suddenly became excited.

After the researchers received the news, they quickly put down their work and gathered in the conference room.

Although the researchers have been conducting their own research recently, they lack the leadership of Li Donglai.

They always feel that the projects they have launched are of no great use at all, and the success rate is too low.

Seeing Li Donglai walking in, everyone immediately started talking.

"I don't know what new things our laboratory will study this time."

"A while ago, didn't our laboratory have a few veterans from the military industry? I think our Director Li wants to research military products this time."

"Is it a big tank or a big plane? That would be great. Don't think I am a medical professional. When I was in school, my dream was to become an aircraft designer."

This chapter is not over yet, please click on the next page to continue reading! "I think we should study tanks. Now that the south is not peaceful, we especially need tanks."

Li Donglai coughed twice, and the conference room suddenly became quiet.

When everyone turned their attention to him, Li Donglai slowly said: "I wonder if you have heard of a transistor radio?"

As soon as this statement came out, it immediately triggered a burst of discussion.

"Transistor radio? I heard that there is a radio produced by Sony abroad. The transistor is smaller in size and cheaper. And the sensitivity is better than our domestic tube radios, but it is difficult to transport it into the country.

"

"We also have transistor radios in China. The Radio Technology Research Institute in Shanghai successfully trial-produced the first germanium diode and germanium transistor. However, because the stability was so poor, it did not become popular."

"Yes, yes, I have an old friend who works there. He bought one at a high price, but he couldn't even find a radio station. But he was very angry."

"Isn't this thing useless at all? Why do we still study it?"

"Yes. I feel that researching something with no future like transistor radios is better than researching big airplanes and tanks."

Hearing the discussions among the researchers, Li Donglai smiled bitterly and shook his head.

We can't blame these researchers for being short-sighted.

After all, without the memory of later generations, he would not have been able to realize that the semiconductor technology used in transistor radios would become the mainstream technology that would change the world in the next few decades.

That's right, the ultimate reason why Li Donglai wanted to study transistor radios was to study chips.

In later generations, because domestic chip technology was too poor, we were often blocked by others. After arriving in this era, Li Donglai had the idea of ​​​​researching chips.

But he knows that the most important reason why it is difficult to achieve breakthroughs in chips is that it is a huge industry and requires cooperation from all aspects.

It is difficult for just one person, one factory, one laboratory, or even a small country to support the chip industry alone.

Therefore, to study chips, we must not only start from the basics, but also develop domestic semiconductor technology.

In addition, the radios currently used in China are mainly tube radios.

This kind of radio has a lot of power and consumes a lot of power.

Although a tube radio does not use much electricity, you must know that there are thousands of tube radios in China, and countless amounts of electricity are wasted every year.

If we eliminate tube radios and use transistor radios instead, we will definitely save a lot of energy for the country.

In addition, once transistor radio technology matures, the materials required to manufacture transistors will be much lower than those required for tube radios.

In this way, the selling price of the radio can be reduced.

It is more conducive to enriching people’s entertainment and cultural activities.

After all, in this day and age, most people still can't afford a radio.

Therefore, the development of transistor radios is a matter of great advantages and no disadvantages.

Li Donglai was quite dissatisfied when he saw the researchers and patted the table gently.

After they calmed down, he said with a smile: "When Watt invented the steam engine, many people thought that the steam engine was useless at all. Not only was it dangerous, but the power it provided was far inferior to two horses.

But with the development of steam engines, people have created trains that can carry tens of thousands of tons of cargo, and ocean-going ships that can carry hundreds of thousands of tons of cargo.
