All the way to Nanhu City, Tu Xian thought that he was going to the towns below. For various reasons, he went to Nanhu Science and Technology Commission and asked about the local situation.

Tu Xian took out the work permit of Beijing Iron and Steel Institute, and immediately received warm reception from Nanhu Science and Technology Commission.

This is not the good service attitude of Nanhu Science and Technology Commission, it is purely because of Tu Xian's status.

80 University Teachers in the '80s are still highly respected. Their social status is different because of their school and professional knowledge.

But generally speaking, university teachers usually have the knowledge urgently needed by other units and enterprises,

For example, Xibao meat factory last year did not play the ribs can production line, you want not to lose money, leaders do not want to be criticized by the superior, staff and cadres do not want less bonus, you can only find people who master technical knowledge to help you.

In the 21st century, most of the open technologies are mastered by many people. Even if they are relatively high-end technologies, there are more than one experts and scholars who can hold meetings in the same field. How can they fill a hotel. We can't find anyone in China, so we can invite people from abroad. There are professional technical consulting companies all over the street.

If the requirements are not high, graduate students like Yang Rui can deal with it by checking the information.

However, in 1983, regardless of the public technology or the non-public technology, there were very few people who mastered most of the technology. No one could understand most of the technology there. Most of them were people who didn't know how to find information. They searched all over the country for a little high-end things, and only one or two people could do it.

But on the other hand, it's different. People who understand technology often master more than one technology, but many technologies. There are many people who ask them for help, and their time is limited.

Why are there so many inventors and technological innovators in this era? They are all self-taught talents forced by the environment, and they are also helpless paths to solve technological problems in China.

After 20 years, when the country has trained tens of millions of college students, there will be few similar news reports. It is news for workers to improve their technology, but it is not news for college students to improve their technology.

Scarce knowledge, in the 1980s in China, can be regarded as a kind of power like existence.

As a lecturer of Beijing Iron and Steel Institute, Tu Xian is equivalent to a novice science magician. People of Nanhu Science and Technology Commission may not be able to use him now, but they don't have to be stingy.

A young office clerk was sent out to not only introduce Tu Xian to the local situation and precautions, but also accompany him to get on the bus and help him buy tickets. After giving instructions to the driver, he finally left.

Tu Xian sat comfortably in the front seat by the window, waiting for the departure.

The old man next to him was not only bored, but also curious: "are you a cadre in the province, going to Xibao middle school?"

This time it was Tu Xian's turn to be curious and asked, "how do you know?"

"I haven't seen your clothes in Nanhu City, and so have your shoes. They are new. No one in Nanhu city wears them like this." Old man has the potential of Sherlock Holmes, but there are few commodities now.

Not only Nanhu City, but also Pingjiang city has no large-scale clothing market. Ordinary people always go to department stores to buy clothes, and the commodities of department stores have been there for many years. Some models have been sold since the 1960s, and they are still sold until the end of the 1980s. Factories continue to produce without giving up, and even the production line does not need to be changed. Saving money is really saving money.

In contrast, big cities like Beijing, Beijing and Shanghai are different. Although they are not as colorful as they will be 20 or 30 years later, people always have more choices, and there is not only one department store.

Although Tu Xian is an ordinary teacher, he or his wife can always buy good things in line, which is unmatched by people in Hedong province.

Tu Xian looked at the people around him. He couldn't help laughing and said, "I'm from other places, but how do you know I'm going to Xibao middle school?"

"Intellectuals like you always go to Xibao town." The old man said with a smile and said, "the bus you are taking now is a new one. Do you know?"

Tu Xian was surprised. He sat up and said, "I don't know. What is it for?"

"Xibao meat factory in our town has built a new factory with foreigners, don't you know? A lot of people came to investigate. Our Xibao town is a place where talents come from... "

"Factories built with foreigners?" On weekdays, Tu Xian's access to information is through radio and newspapers. In Beijing, it's hard for him to know what happened in Hedong province. He knows about Jericho's plan to build a factory in Tianjin, but he doesn't know anything about Xibao meat factory.

The old man could not say why, nodded yes, and asked, "what do you do?""I'm a university teacher."

"Where's the man?"

"I'm from Nanhu Science and Technology Commission. I don't know the way. Please introduce them."

"I'm afraid that something will happen in the town?"

Tu Xian had an awkward smile.

The old man also laughed and said, "it's nothing. There are a lot of bandits and road bullies now. Last time I went to my relatives' house, I took a big bus. People robbed me on the road. It's a shame to say that all the people in the car watched me and let me take away the money from the conductor."

"Didn't take the passenger's money?"

"They dare!" The old man glared: "if you want the passenger's money, isn't it hard for you?"

Tu Xian said "yes" with a smile.

The old man was very proud and said, "I don't know you come from big cities. Some places are chaotic... No, you know, how can we say that?"

Then, the old man began to say, "it's said that if you learn mathematics and chemistry well, you will not be afraid to travel all over the world. I think you are afraid."

"Yes, it must be."

"If you're afraid, you can find the municipal Party committee, but not the ordinary people."

"It's the Municipal Committee of science and technology, not the Municipal Committee. Besides, I am also a common man. "

"You are a cadre, not the same." The old man moved his butt and said, "my grandson went to middle school this year. He will report to Xibao middle school and become a cadre in the future."

Tu Xian was not going to chat. When he talked about Xibao middle school, he could not help asking questions.

The old man once again showed a proud smile, grabbed the dry tobacco pole from his waist, rubbed the tobacco leaves, and began to talk while smoking.

For the residents of the town, this year's Xibao middle school has a lot to say.

It took the bus more than two hours to get to Xibao Town, but it was much faster than before. Just two months ago, from Xibao town to Nanhu City, we had to go to Xi county first, and then from Xi county to Nanhu city. Now, although the road has not changed, the waiting time for changing buses has been saved. If we calculate the average time, it can be reduced by more than two hours.

Tu Xian asked the way to Xibao middle school in the car. After a little rest, he ran to the hill in the West.

It wasn't long before we saw the gate of Xibao middle school.

Tu Xian showed his work permit to the porter and was able to enter. When he turned the corner, he saw a large area of open space surrounded. A liberation truck was driving slowly under the attention of more than a dozen students.

"This is the truck that the school bought to learn how to drive?" Tu Xian asked the roadside students.

The student said, "school? It's bought by Yang Rui for free. "

"Yang Rui? Ah, where is Yang Rui? " Tu Xian can't think of anything else.

The student pointed to the open space and said, "standing there, it's the one in sportswear."

Tu Xian looked at it for a long time and said strangely, "is that a student?"

"Yes."

"I'm not asking about Yang Rui. I'm asking about Professor Yang Rui or an associate professor. In a word, he should work in universities and research institutes." Tu Xian recalled that he didn't ask Yang Rui about his work unit seriously. The letters between them were so serious that he didn't have time to talk about private affairs. Now he is ready to talk about private affairs, but he has to find someone first.

The student shook his head and said, "then I don't know. However, Yang Rui has a research laboratory."

"Research lab? What kind of lab? "

"It's a laboratory with many instruments and flasks. If you want to call it a research laboratory, it's more complicated than our student laboratory."

"Well, I see." Tu Xian decided to have a talk with Yang Rui, a student with the same name and surname in the same school.

With these thoughts in mind, Tu Xian went into the dusty driving range and said to Yang Rui, "Hello, I'm Tu Xian from Beijing Iron and Steel Institute..."

"Ah, you arrived as soon as I got the letter? Hello, I'm Yang Rui. It's my first time to meet you. I didn't expect that Mr. Tu is very popular. " Yang Rui and Tu Xian shook hands cordially. They didn't hesitate because they were young, but they were more excited to meet "Xinyou".

Tu Xian is numb.

It is Yang Rui's nickname for his originality. Many plants selected by Tu Xian are famous poisonous plants, including Narcissus, Calla Lily, tulip, Bauhinia and so on.

At that time, Tu Xian readily accepted that he could be called unique by Professor Yang. He was very happy in his heart, indicating that he was in his eyes.However, when Professor Yang became Yang's classmate, Tu Xian felt strange.

A middle school student! How can I teach in the Institute of iron and steel?

Smiling, Yang Rui continued to shake hands with Tu Xian.

Tu Xian really caught his eye.

For scientific researchers, what matters is not what answers they give, but what questions they will ask.

In Yang Rui's view, the question that Tu Xian wrote to ask is a very good one. If it is solved, it means that he is on the right road.

What's more, Tu Xian is in Beijing to facilitate Yang Rui's next work arrangement.

Yang Rui therefore actively answers Tu Xian's question. As for Tu Xian's current stupidity, Yang Rui doesn't care much.

19 For example, at the age of 19, Lagrange communicated with Euler to discuss the "isoperimetric problem", which laid a theoretical foundation for the variational method. In the same year, Lagrange became a professor of the Royal Artillery school in Turin. At the age of 20, Lagrange was appointed as a communication academician of the Prussian Academy of Sciences on the recommendation of Euler, No matter the contemporary European scholars or all the students who studied science and Engineering 200 years later and were tortured by Lagrange's theorem, they had to give their knees to the 19-year-old Lagrange.

Yang Rui has technical knowledge beyond the times. His age and identity have been covered by knowledge.

No matter whether Tu Xian is willing or not, he has to turn around by himself.
