country made

Ji Jianguo was very familiar with this voice.

When he first bought the radio, he debugged it almost every day, carrying the big and heavy radio around the room and trying to find a place where he could receive the signal. .

It's like the sound from the integrated circuit in front of you.

Ji Jianguo stared at the pile of integrated circuits with wide eyes, his face full of shock: "This is... a radio?"

Ji Yu nodded: "If you are in the city, you can receive the radio station, I tried it."

"How is it possible..." Ji Jianguo stretched out his hand out of the integrated circuit group, fearing that the wire would be damaged, so he withdrew his hand, just looked at the small integrated circuit group, and asked in disbelief: "This, such a small integrated circuit , how did it become a radio?"

Shouldn't radios be big and heavy, like big concrete bricks?

"The principle of the radio is actually very simple, and it doesn't need so many components." Since Ji Yu wanted to teach his father the mini radio, he naturally had to let him understand the principle, and continued: "The principle of the radio is to transmit the high-frequency signals received from the antenna. The frequency signal is restored to an audio signal by detection, and then sent to the loudspeaker for sonication. So what really works is the high-frequency amplifier, frequency converter, and the frequency selection circuit to cut off the amplitude change of the FM wave, and drive the speaker through power amplification... "

"Wait, wait." Ji Jianguo waved his hand to stop him: "I can't remember what you said, so you should write it to me!" He pointed to the mini radio on the table and said: "This circuit group, you can do it again. I read."

Ji Jianguo was also a senior technician before. Although he hadn't worked as a technician for many years, he had a good understanding of electronics. After Ji rafter wrote out the principle of the radio, he drew a circuit diagram and he understood it completely. .He could reassemble a radio's integrated circuit by himself without even Ji Rafter's guidance.

It is impossible to build a factory. Although Ji's family is rich now, they do not have the qualifications to build a factory. Self-employed are fine.The next day, Ji Jianguo began to rent an office building in the city to apply for a business license.These Ji rafters can't help, so they can only help Ji Jianguo draw a few more fashionable radio exterior designs at home.Considering that there is no patent protection yet, it is almost conceivable that it will be imitated as soon as it goes on the market. Ji Zhuan has drawn a fashionable eagle-shaped Logo, and we can only expect people to recognize the brand.

When Ji Jianguo got his self-employed business license, Ji Zhuan was about to start school.

Ji Jianguo came back to see him off on purpose, maybe because he was too nervous, he actually bought all kinds of things from the city and wanted Ji Yu to bring him to school, but Li Shulan gave him a good reprimand.

Ji's family lived a simple life, but they still spent a lot of money for Ji Zhuan.I bought new clothes, shoes, gloves and socks for Ji Zhuan, all of which were the latest models bought in department stores in the city, for fear that Ji Zhuan would be ridiculed for being rustic when he arrived in the big city.

Ji Zhuan was already good-looking, but with his new fashionable clothes, he looked more energetic and fashionable. He looked like a young man from a big city.

After finally trying on the clothes, seeing his parents and grandpa still discussing what to bring in his suitcase, Ji Yu ran back to Brother Song's house.

Because of the entanglement of the neighbors and elders, he now lives at Xiao Song's house most of the time.

Along the way, Ji Zhuan's brand-new and fashionable clothes attracted the attention of many neighbors, and the elders all smiled and called him: "Hey, Yuanyuan, are you wearing new clothes?"

"Ji Zhuan, you look so pretty, like a city dweller."

Ji Chen could only giggle, he didn't think the fashion clothes at this time were good-looking at all, if his parents hadn't bought them in advance, he wouldn't have worn them at all, he still prefers plain white shirts.

After walking through the main road, and then through a small road, you will arrive at Brother Song's house.Just as Ji Chen turned the corner, he heard a gust of wind behind his ears, as if something was coming.Before he could think about it, Ji Yu dodged, grabbed the opponent instead, and fell hard over his shoulder, cross-locked, and the opponent screamed and struggled on the ground.

Ji Yu buckled his arm and asked, "Robbery?"

"Ah, let me go..." The other party couldn't speak clearly, and struggled hard again, Ji Yu couldn't see his face clearly, afraid that he would run away, so he grabbed his kicking foot with his backhand and twisted it, making a click , I dislocated my ankle, and now I can't run even if I want to.

No matter howl the other party yelled, he would not be soft on the robber Ji Zhuan. He pressed the other party's shoulder, twisted it again, removed both arms, and then turned him over.

The suspected robber looked a little miserable, because when he turned the opponent over just now, he used too much force. It seemed that his face hit the ground, his nose was bleeding, and one of his front teeth fell out, and his mouth was full of blood.Ji Chen thinks he looks familiar, but he can't remember, he is much taller and stronger than Ji Yuan, but he looks like a middle school student at most.

"Tell me why you attacked me. If you don't answer, I will call the police station."

The atmosphere in the town has always been simple, and there are very few incidents. He just wore clothes that looked like city people, and he was attacked when he went out. Of course, his first reaction was to think of robbery.

"Yi Quan... I can't beat you..."

The boy's nose was crooked, his mouth leaked, and he was lying on the ground staring at Ji Zhuan with tears in his eyes. He couldn't speak clearly. After listening to it for a while, Ji Zhen realized that he was saying, "Ji Zhuan, I won't let you go." .”

"Huh? Do I know you?" Ji Yu looked left and right at his blood-smeared face, and felt familiar, but couldn't remember where he had seen it.

"Are you trying to rob or what? If you don't tell me, I'll call the police as robbery."

A trace of fear flashed in the young man's eyes, robbery is a felony, even if he wanted to scare Ji Yu, he would not dare to admit it.Staring at Ji Yu, seeing his serious face, he could only soften his voice and say, "I'm Zhang Jin."

His mouth leaked, and he couldn't say his name clearly, but Ji Yu immediately understood who it was.

Zhang Xin, the youngest son of Zhang Ermei's family.

Ji Yu hasn't seen these three brothers for a long time since he got together with Brother Song.

In fact, the three brothers of the Zhang family also have some mixed names in the town, especially the eldest brother of the Zhang family is also a gangster in the town.But compared with Song Jining, it is far worse. When Song Jining helped Ji Yu beat his two younger brothers with black noses and swollen faces, he didn't dare to come out to take revenge.Ever since Ji Yu and Song Jining were discovered together, the eldest brother of the Zhang family forbade them to trouble Ji Yu again. In addition, the child grew up fast, and Zhang Xin's appearance was not the same as when he was a child.

Although he is only 12 years old and only in the sixth grade at the beginning of school, he is much taller and stronger than the 13-year-old Ji Zhuan.

Ji Chen is really bored with the Zhang family, he obviously didn't offend the Zhang family, and he doesn't understand why the Zhang family brothers keep making trouble for him again and again.

"So? You're not robbing? Why did you hit me?"

"Look at Yi (you) is not pleasing to the eye."

Well, that's a really good reason.

For the unreasonable Zhang family, this reason is enough.

"I'll call the police as robbery!"

Having said that, if the crime of robbery is not necessarily punishable by death, Ji Chen really wants to call the police.No matter how much he hated Zhang Xin, he would never kill someone just because they tried to beat him.

But he removed Zhang Xin's hands and feet, and didn't want to help him reattach them, so he clapped his hands and prepared to leave: "I'm going first, you can find someone to save you by yourself!"

"You just let him go like this?" Song Jining who didn't know when he appeared asked.

Ji Yu froze for a moment: "Brother Song, so you are here?"

"I wanted to pick you up, but when I saw some sneaky guy on the road, I followed him." Song Jining patted Ji Yu on the shoulder, his face full of admiration: "Not bad, you finally defeated Zhang Xin, and you deserved it." It took so long to teach you. Next time we will try with Zhang Jian."

Ji Chen remembered that when he learned how to fight with Brother Song, he said that he should be able to bring down Zhang Xin now, Zhang Jian still has to look at the physical difference between the two sides.But after studying for a long time, he forgot that his original intention of learning to fight was because he was bullied by brothers Zhang Xin and Zhang Jian.

But he wasn't happy at all.

Because he remembered that Zhang Xin was only 12 years old this year, one year younger than him.Although he is tall and strong, he is actually a sixth grader.

Would he feel a sense of accomplishment in beating a primary school student?

Hearing what Brother Song wanted to fight with Zhang Jian, Ji Chen waved his hand: "No, I don't want to see the Zhang family brothers again, and Zhang Jian doesn't want to mess with me."

Ever since Song Jining beat him up, the Zhang family brothers have never troubled him again, and the two sides have hardly met each other. If Zhang Xin hadn't come out today, Ji Yu would have forgotten the existence of these three brothers.

If he went to trouble Zhang Jian for no reason, wouldn't he be the same as Zhang Xin?

"Okay, then let me deal with this guy!" Song Jining squeezed his fists, and threatened Zhang Xin into a corner. After a while, Zhang Xin ran out with a look of panic, not even daring to look at Ji Yu , Swinging away with both arms hanging down.

The author has something to say:

"I connected his feet for him, otherwise he won't be able to roll." Song Jining said, stroking Ji Zhuan's hair: "Don't worry, he dare not tell you about beating him."

"I'm not worried." Ji Yu raised his head and smiled at Song Jining, looking very obedient: "For an excellent student like me, even if Zhang Xin told others that I beat him, no one would believe him."

Ji Chen himself never caused troubles, but he couldn't stand things to provoke him.Because a person with excellent grades is well-behaved, basically no matter how others frame him, it is difficult for anyone to believe him to do bad things.This can be regarded as Ji Chen's experience.

Song Jining looked at Ji Yu's tender face, and imagined the scene when someone said to him "Ji Yu hit me".

Well, he absolutely didn't believe it.

"It turns out that being a good student has such advantages..." Song Jining rubbed his chin, and the idea of ​​being a good student became firmer.
