country made

Ji Yu felt that Song Jining was still just a child, but Song Jining considered himself an adult, and began to think about problems with his meager knowledge.

First, after making sure he had firmly memorized how to make a radio, he dismantled the one he made: "This must not be seen."

Fu also told Ji Yu: "Uncle Ji, you have to tell him to be careful and don't let others know. Especially Ji Yong, that guy has a big mouth and can't hide anything. Then a group of relatives and friends will come to follow you If you want technology, you don’t want to do anything.”

He thought that Ji Jianguo must know, after all, his family wanted to build a factory!

Ji Yu nodded vaguely.

If he said to his father now: "Dad, we will build a factory in a few years, and I have already planned what the factory will do."

His parents will definitely give him a mixed doubles, and then scold: "What are you thinking about, you should study hard for me."

Before the policy came down, anyone who wanted to build a factory would be regarded as a capitalist roader, and young people of Song Jining's age were willing to accept future changes.

After making an agreement to temporarily hide other people, Song Jining felt closer to Ji Yu because of the little secret shared by the two of them, and asked with a smile: "Speaking of Yuanyuan, did you draw the design of the radio yourself or did Uncle Ji help you?" You? How do you know so much, all from these books?"

Song Jining was referring to the pile of reference books on the table.He is not as lucky as Ji Yu, he has a powerful father who loves him, so he has to plan everything by himself.

If these books are so powerful, he will have to buy a few to learn.This is much more profitable than repairing electronic watches.

"I drew the blueprints myself. An uncle from the farm taught me a lot about electronics." Ji Yu still used the old excuse of the farm uncle: "Of course, you can learn a lot from these books, my little one." If Brother Song is interested, how about I teach you?"

"Huh? Are you willing to teach me?"

Ji Yu was eager for him to learn, and nodded eagerly: "Yeah, let's start with the principle of radio, because you have made it yourself, this will allow you to understand the role of electronic knowledge more intuitively."

"Huh? You even taught me that?!"

Song Jining was extremely shocked.

Although he has made it himself and seen the design drawings, he doesn't understand the principle at all. This should also be the core technology of the radio.

Is Ji Zhuan planning to teach him even such an important thing?

In fact, Ji Chen not only taught him the principles of the radio, but also taught him how to draw design drawings. After drawing and drawing, according to other accessories, Ji Chen drew two more designs of radios.

"Although the design drawings look completely different, in fact the principle of the circuit diagram is the same. It is to restore the high-frequency signal received from the antenna to an audio signal after detection, and then convert it into a sound wave by a loudspeaker..."

"Wait, wait, enough is enough."

Song Jining covered his eyes to prevent himself from looking at the two design drawings: "Put it away so that no one can see it. This is a core secret, and I shouldn't learn it."

As for the design drawing of the first type of radio, after Ji Lian's explanation and drawing, he has fully grasped the principle. Now let him do it himself, and he can definitely draw it without any mistakes.If he continues to study, he is worried that he will not be tempted to sell a design drawing, and then use the money to build a factory by himself.

Of course, as a teenager who is obsessed with the Romance of the Three Kingdoms, he is determined not to do such ungrateful things.

Ji Yu was puzzled: "Is Little Brother Song tired?"

"No, I'm afraid that if I learn too much, I won't be able to control myself and do bad things." Song Jining thought of this and taught Ji Yu: "Yuanyuan and you too, how can you teach such an important skill casually, what if I am a bad person? What if I What are you going to do if you sell the blueprints to others?"

Then design a better one.

Ji Chen has no worries about this at all.

But he also reflected on his behavior.His trust in Xiao Song comes from his future teacher, but Xiao Song is not a teacher who will be flattered or humiliated in the future. On the contrary, he is a young man who is short of money.

His current behavior is equivalent to using a huge sum of money to test whether Xiao Song is a good person, which is too risky.

It doesn't matter if Xiao Song takes away the design drawings, but if it causes a rift between the two of them, it will be a gain and loss.

"I'm sorry, I didn't think carefully." Ji Yu tore up the design drawings: "For the time being, I will only teach Little Brother Song the knowledge in the book. If you want to know anything outside the textbook, ask me."

"That's right." Song Jining rubbed his hair: "That's why I won't be ungrateful. Another person may lie to you. You are not allowed to trust people so casually in the future."

Ji Chen agreed with a smile.

If the object is not a teacher, he will not trust it so much!

In the blink of an eye, school starts, and Ji Yu is still studying his first grade.Several sixth-grade teachers who taught him failed to persuade the principal to let Ji Lian skip a grade. They felt sorry for him, and felt that a gifted child had been delayed by the principal.On the day Ji Yu came to sign up to pay the tuition fee, they took him directly to the principal's office and took out a few sixth grade final exam papers they got from the city's primary school.

Shi No. [-] is the best key primary school in the city. The exam questions are much more difficult than Hongxing Primary School, but it is not difficult for Ji Chen.So the teachers once again put forward the request of skipping a grade with Ji Zhuan's nearly double hundred grades. Principal Wei refused under pressure, which caused another quarrel.

Ji Yu gave Principal Wei a sympathetic look, and slipped away silently.

Because the teachers are all extolling Ji Zhuan's reputation as a "gifted child", what he got in return is the trouble of Ji Zhuan being often called by name in class. The advantage is that he got the tacit approval of the teachers for reading extracurricular books in class.

On the other side, after Song Jining returned to school, he began to study mathematics and physics.Because Ji Yu said that these two subjects are very important, and it is related to whether he can manufacture electronic machinery that is more advanced than radios in the future - if he can make money by learning this, it will be much more comfortable than entering a factory.

Song Jining, who took this as a comparison, finally had the motivation to learn.

Not long after the start of the new semester, there was news in the newspaper that both Ji Yu and Song Jining were extremely excited about.

Lushi changed the Oriental Department Store into a clothing retail store, with the "store" as the structure, improved the shopping environment of the original closed store, and allowed individuals to lease and privately own the store.

Newspapers called it the courage to "break the ice" and praised it highly.

What Ji Yu saw was the budding of the free market, while Song Jining was concerned about private profits and the possibility of private factories.

Private shops are allowed, will private factories be far behind?

As Ji Yu said, it may start in a few years.

He must prepare early.

Money, Song Jining can't get it out, technology, he is not as good as Ji Yu!

Since the Ji family found him and wanted him to be the factory manager and engineer, he should have prepared for this early.

He had never been a factory manager before, and he didn't know what to do, so he had to ask his mother for help and go to a glass factory for an internship on weekends.

Huang Yan didn't know that her son was going to be the director of the factory, so she thought that Song Jining wanted to work in the glass factory, so she happily agreed.If the school can't be assigned a good factory, she is also going to let her son work in the glass factory through the back door.

The employees of the glass factory are all from the town, so they are no strangers to Song Jining, so he did not encounter any difficulties when he entered the factory, but he was not allowed to wander around.Song Jining was by his mother's side, watching the team leader and how the technicians worked attentively, and he also used the excuse of going to the toilet to see how the factory manager and supervisors were working.It's a pity that I didn't see them working, only the office was filled with smoke, and everyone looked sad and tired.

It is said that the output of the glass factory has decreased by one-third this year, and the production may not be sold, so the factory manager and supervisors are probably worried about this.

Song Jining did not learn the skills to be a factory manager in the glass factory, but only felt the competitive pressure of the market.

Ji Chen said that the radio is an entertainment product, and it will be updated very quickly. The design drawing drawn now may be researched by someone in a year or two, so let him not care about it, because he will design a better product.

Song Jining didn't know where his confidence came from. Now this radio that he could carry with him was already great. How much better would it be?

At that time, Ji Yu pointed to the pile of reference books with a smile, and said, "Once you learn these, you will naturally understand."

So Song Jining took the pile of reference books home.

Although he wanted to delve into it, he still didn't understand it because of his poor foundation.Ji Zhuan now teaches him a little bit every day, but he always feels that he has not learned enough and understands too little.

Ji rafter taught him the radio, and he already knew how to draw design drawings, but he failed to draw the fourth design drawing by himself except for the three design drawings drawn by Ji rafter.

In order to supplement his extra knowledge, Song Jining often went to the maintenance department in the town again.

The uncle in the maintenance department was originally a technician in a machinery factory, but his hand was injured by a machine. In order to arrange for him, the factory opened a maintenance department.Nominally, it is used as the logistics of the factory, but he is basically not needed, so he puts up a list to repair household appliances and bicycles by himself.He is a very capable person, and Song Jining used to admire him very much—after getting to know Ji Yu, this feeling of admiration disappeared.The 10-year-old Ji Zhuan can also do these things.

Song Jining used to steal a teacher there for a period of time, and once again he was very familiar with stealing a teacher.

The uncle in the maintenance department is also a good person, and he never chases them, a group of children who join in the fun.Children like to squat aside and watch the uncle repair electrical appliances. Firstly, they are free, and secondly, they are curious about how electric fans and bicycles are repaired, but they just watch the excitement, not knowing why.

Song Jining understood it without a teacher.

He used to steal a teacher to repair his own electric fan, but he only learned the repair method, but didn't understand the principle.

However, he found that he understood now.

For example, in the past, he only knew that the speed control gear of the fan did not respond because the wiring was loose, but now he realized that the linkage rod was loose, which caused the contact switch to fail to connect to the key frame, so the speed control gear did not respond.He also knows the bidirectional thyristor that starts the fan. It was only called a circuit before, but now he understands what it is and why it is used because he has read it in a book.

What he read was not books introducing fans, but just explaining the techniques and principles of some things. After understanding these principles, Song Jining felt that he would naturally understand the operating principles of fans.

Then he finally understood why Ji Yu could design the radio by himself.

He looked at the accessories of these fans and thought about its principle in his mind. Song Jining found that he seemed to have understood the operation principle and manufacturing process of the fan, and he could draw a complete circuit diagram based on the existing materials, and even the The knowledge learned in the book has been slightly changed.

I really want to try to see how far I have learned.

Song Jining got up excitedly and was about to go home to draw pictures, but was suddenly stopped by the maintenance man: "Hey, that guy in blue."

He looked at his blue coat and asked, "Uncle Peng, did you call me?"

The uncle in the maintenance department is surnamed Peng, and Song Jining called him uncle out of respect, but they have nothing to do with each other.

"Come here and help." Uncle Peng didn't even lift his head, but only ordered: "Check if there is any problem with the power switch."

Song Jining hesitated for a while, then knelt down to help check.The SCR control was extremely loose and failed to trigger the voltage, causing the power switch to fail - well, simply the wiring to the switch button was loose.In the past, he could only understand it this way, but now he only knows the principle of silicon controlled rectifiers, and he knows where the problem lies.

These are taught by Ji Chen.Ji Yu said that the principle of electromechanical is universal, and it is true.

He obviously learned it for the radio, but it turns out that electric fans are self-taught, and his knowledge of electromechanics is really incredible.

Uncle Peng was very satisfied with Song Jining's repair results, and asked him kindly: "You have come to my place often recently, do you want to learn how to repair fans? Haven't you been here before, and you haven't learned yet?"

He has sharp eyes, and he can tell at a glance who is here to watch the excitement, and who is sincerely interested in learning techniques.

Being caught stealing a teacher, Song Jining smiled embarrassedly: "I fixed the fan at home by myself. I wanted to watch the radio this time, but unfortunately I didn't."

Uncle Peng said hi: "I can't receive the signal here again, so I don't use much."

There are not many families with radios in the town, the main reason is that they cannot receive radio stations here. Back then, including Ji’s family, several families spent a lot of money to buy radios in the city, and took them home happily. You have to pull a long antenna around to get a little bit of sound, and no one bought it anymore.On the contrary, almost every household has an electric fan. Uncle Peng repairs the electric fan most often, and the radio is only occasionally.

Uncle Peng was very satisfied with Song Jining's repair skills, and after observing him these days, he felt that he was a very patient and hard-working young man, so he said: "I want to take in an apprentice recently, and I think you also want to learn one. How about the craft, do you want to come to me as an apprentice?"

Song Jining: "Huh?"
