Jiang Yan didn't know why he was so enthusiastic about the two little guys' school problems today, so the eyes that looked at Yan Bugui were a little weird.

Yan Bugui saw his curious gaze, and immediately understood what this stinky boy was thinking, he said helplessly: "What kind of eyes are you kid, I know that in your eyes, I am a little picky, but at least I am a teacher, and I can't do anything about our children, but you kid must not question my professional ethics, otherwise don't blame me for being anxious with you, I'm not afraid of delaying these two good seedlings." ”

Hearing him say this, Jiang Yan understood, and for the first time, he said to Yan Bugui with sincerity: "I'm sorry Mr. Yan, it's because I've thought too much about it, and I've spent your gentleman's belly with the heart of a villain." ”

"In fact, I also have certain considerations for not letting them go to school so early, you also know, today's children are a little wild, and they will pull their fists at every turn, I don't want them to go to school so early for fear that they will suffer, in fact, it doesn't matter if they go to school for two years, there are some things I can teach them at home, I still know the importance of education."

Seeing that his kindness was actually rejected by others, Yan Bugui also shook his head helplessly, if you want to say that you are not careful, then you really underestimate Yan Bugui, he is now an acting teacher, not a formal teacher, if the school knows that he brought them two little prodigies, it is estimated that his agent will have to be removed.

Also, he can bring two prodigies, and he has face in front of his colleagues, but it seems that his plan to show off in front of his colleagues is about to come to naught.

However, Jiang Yan didn't let him go empty-handed this time, and casually stuffed the two taels of tea on the table into his hand, which also made Yan Bugui's face smile again.

On the one hand, there is the help of Aunt Yang and the old lady and Qin Huairu and others at home, and on the other hand, Yiyi and Yuehao can also help take care of the two little sisters at home, which makes everyone in the courtyard who knows it amazing, knowing that the two children of Jiang Yan's family are sensible, but they didn't expect to be sensible to this extent.

Other people's children also have the eldest to help take care of their younger siblings, but then how can they wait until they are seven or eight years old to be sensible, who has seen a five-year-old child can help their parents take care of their younger sister.

In Yan Bugui's words, these two children are precocious, and naturally they will be very different from other children, and they will definitely have a great future in the future, so the reputation of the two little ones in the yard will be even louder.

Now they are not only envious of Jiang Yan's family's good food and clothing, but also envy the good growth and education of other people's children.

Whenever Jia Zhang's heard these words, he secretly slandered in his heart: What a fart, that is two little bastards who have been black-hearted since childhood.

She had already known the true situation of the incident that day from the words of the stick terrier, but because her grandson was actually calculated by a five-year-old child, if this matter was said, the stick terrier would not be able to mix in the yard, and she also knew that it would cause Jiang Yan to be harmful, so she gritted her teeth and chose to hide the truth.

With the help of others, Jiang Yan completely got rid of himself and once again devoted himself to the development, this time Jiang Yan drew a motorcycle similar to Jialing 70, but strictly speaking, this motorcycle is not a regular motorcycle, at best it is a moped, but the appearance of this car in history is a little ugly, so Jiang Yan is ready to redesign it.

As for why there is an idea of producing motorcycles, this is a few days ago my wife complained to her that her bicycle moped was too ugly, and it was inconvenient to add a small engine to take the child, so Jiang Yan also thought of getting this motorcycle as a gift for his wife's confinement.

However, the overall architecture of this motorcycle is not difficult, and the relevant drawings Jiang Yan has also been prepared early, but this engine has put Jiang Yan in a difficult situation, not that it can't be built, but how to choose the engine.

Originally, Jiang Yan also wanted to use a four-drive small engine, but after doing the math, he felt that it was a bit of a waste to use such an engine on a small moped, so after thinking about it, he decided to use a two-drive engine, and the one with electric hybrid.

There is also the material of the whole motorcycle, the skeleton should be made of stainless steel, but the overall weight of the car is too heavy, after optimization, Jiang Yan's main use of aluminum alloy for the entire motorcycle mineral plus, the rest of the plastic, but the plastic is too brittle, thinking about it, Jiang Yan thought of using carbon fiber to combine plastic.

You must know that we have begun to prepare for the research and development of carbon fiber technology as early as 1962, and even used polyacrylonitrile fiber to develop. At that time, the knowledge of this technology that we had not thought of was very poor, and even if we had, it was very poor, so these studies did not come to fruition. And at that time, when Eagle Sauce and Foot Basin were eyeing us, they couldn't break through in this regard.

Initially carbon fiber was used only in the defense industry, and the technology was kept secret. In the early 70s of the 20th century, China established the Carbon Fiber Research Institute and began to discuss related topics. In 1975, under the leadership of General Zhang, China realized the localization of high-performance carbon fiber and broke through the technical blockade. However, in terms of carbon fiber quality and cost, there is still a big gap between the United States and Japan.

The main use of carbon fiber is as a reinforcing material to composite with resins, metals, ceramics and carbon to make advanced composite materials. The specific strength and specific modulus of carbon fiber reinforced epoxy resin composites are the highest among existing engineering materials.

However, the carbon fiber that Jiang Yan wants to make is the kind of mid-range product in the previous life, which is still one of the two mid-to-bottom formulas that Jiang Yan bought at a high price when their factory made other plastic equipment, but it is also quite advanced production now.

Jiang Yan wanted to use carbon fiber and resin together to make the baffle of this motorcycle, so that the baffle was light and had a certain impact.

As for the paint on the motorcycle and some other decorations, this is for Jiang Yan to think about it, this is a gift for his daughter-in-law, how can he do it if he doesn't care, so this time Jiang Yan's design is extremely serious.

In his free time, Jiang Yan stood by the window and thought, at present, in addition to the car allocated by the state, there is also a three-jumper and two bicycles at home, and it is estimated that after the appearance of this motorcycle designed by himself, the bicycle at home will completely become a decorative item, and how to deal with it is a headache.

In these years, it is a rare thing for a family to have a bicycle, and a motorcycle is popping up in their own home, how do you look at how it is suspected of being a bit of a capitalist, and it will not be because of this in a few years!

Thinking of this, Jiang Yan was taken aback, and then Jiang Yan was relieved, not to mention himself and the old lady, Jiang Sirui's own identity and a room full of calligraphy and paintings, there should be no one who dares to touch himself, so Jiang Yan thought, this high-profile should be high-profile! Anyway, he didn't steal or rob, it was all things that he had worked so hard to get, but he wanted to see who was so short-sighted.
