Siheyuan starts from a better life

Chapter 907 Meeting Sister

After wandering around for a few days, they finally visited the entire city. Jiang Zihan got up early that day to exercise, and almost all the children in their family learned martial arts from Jiang Yan.

Compared to his younger brother Jiang Zimo, Jiang Zihan has a calmer personality, so Jiang Yan's Bajiquan was taught to him almost without reservation.

As for Jiang Zimo, Jiang Yan didn't fool him at all. He taught him all the basic pile work and several routines. As for the eight killer moves, forget it! With his fiery temper, Jiang Yan was afraid that he would not control the severity of his attack.

It was before he joined the army that Jiang Yan taught him the eight killer moves.

But to be honest, besides the two of them, Jiang Zihan is the only one in this family who can control him.

Even so, after he learned some martial arts, he became extremely cocky and even dared to challenge the master who taught him military boxing.

Otherwise, given his temper, why hasn't he dared to provoke his brother for all these years?

After Jiang Zihan finished his breakfast, he felt a little lost. In the past, he either studied, worked, or did scientific research every day. It can be said that he never had a day off, even during his years in Eagle Sauce. When he had nothing to do, he would go to the library and frantically learn some knowledge he could. But suddenly when he was free, he really didn't know what to do.

The main reason is that this guy only went to primary school. Because he was precocious, he didn't have any friends. After that, he lived with these teachers on the farm. He was a real otaku and probably didn't have any friends in the city.

Unlike my second son, this guy just goes around the streets flirting with cats and dogs all day long. He has a lot of bad friends. If you let him out without paying him, he will basically starve to death for several months.

Looking at his bored boss, Jiang Yan scratched his head a little, thought for a while, and said: "You should go to Beihang University to see your sisters first. By the way, go to the Friendship Store to buy some things for them before you go, and buy more snacks for little girls."

His two precious daughters completely inherited the will of his wife. They have been interested in airplanes in the sky for a long time. They were admitted to Yenching Aeronautical University, majoring in mechanics. To some extent, they have inherited the will of Jiang Yan and his two wives.

Jiang Zihan said, "Okay!" and then continued, "Do you want to go see Yiyi?"

"No, he will probably be back in two days, so let's go see the two little ones!"

As the weather got cooler, Jiang Zihan didn't like driving, but he fell in love with Jiang Yan's previous car at first sight. He tinkered with it and repaired it at home for a few days. After all his tinkering, it looked almost the same as a new one.

Riding on his "Cai Zi", he was the best boy. He rushed to the Friendship Store at lightning speed, bought some exquisite gifts inside, and then went straight to Beihang University!

This was his first time at Beihang University. He used to be from Wudaokou University, so he asked the students where the aircraft wing was.

But the people he asked for directions were all boys.

It's not because of his sexual orientation, it's because the girls Jiang Zihan had met before were too enthusiastic, whether in Hong Kong or abroad, their enthusiasm was a bit abnormal. Jiang Zihan was most afraid of trouble, and he didn't want to waste time.

Following the guidance of his classmates, Jiang Zihan quickly found the Aircraft Department.

At this time, the open space in front of the aircraft department building was very busy. Many students were making things by hand and conducting experiments on the playground. There were also many other people watching.

Seeing this, Jiang Zihan became very interested and wanted to know what the level of college students is now, so he walked over there unconsciously.

Under limited conditions, the students made toy racing cars, electric fans, ship models, and rocket power simulations with clinker bottles. Although the materials were very simple, they were quite creative. Jiang Zihan came to the student who made the electric fan and saw him plug in the battery. Then the electric fan emitted light, the temperature gradually warmed up, and then in less than 3 minutes, it suddenly caught fire.

The student looked helpless, scratched his head, started to pack up his things, and went back to repair it slowly.

"Classmate, your idea is correct and the creativity is good, but the materials are not good. It's not your fault." Jiang Zihan saw the problem at a glance and couldn't help but speak.

The man who heard Jiang Zihan's words looked up at Jiang Zihan and said, "I know, but I only have these materials. I can only think of a way to lower the temperature and see if it can be popularized among the people. After all, the winter in our city and even in the north is too cold."

"It's impossible. The external conditions are simply not met. After all, the electric heater requires a relatively high voltage, which is not available in our country at present. Besides, how much electricity is used for one minute? The electricity bill is too expensive. It is not as good as using coal briquettes for heating. It is not very practical. Besides, ordinary people can't afford it."

There was nothing wrong with what Jiang Zihan said, but it made that student withdraw into himself. He himself had not thought that he had so many shortcomings. From Jiang Zihan's tone, it seemed that he was worthless, which directly made him withdraw into himself and he did not want to talk anymore.

"Student, don't be discouraged. When our country has the conditions in the future, it can still be promoted on a large scale. But by then, your thing will probably be eliminated. After all, it is unsafe and unhealthy over time. You can try making an air conditioner! This thing can be used in summer or winter, and it is much better than your electric heater."

"Air conditioning? I haven't used it before! But teacher, do you understand?" Because Jiang Zihan was dressed too maturely, the student thought he was a teacher in their school.

"I know a little." Jiang Zihan nodded.

"Then teacher, can you tell me briefly?"

Jiang Zihan, who originally wanted to reject him, couldn't bring himself to say no when he saw the hopeful look in his classmate's eyes.

"Well, okay! I'll tell you briefly, and you give me your pen and notebook."

The classmate quickly handed the notebook and pen to Jiang Zihan.

Jiang Zihan took the book and started drawing on it. After he finished drawing, he began to explain it to him.

"Air conditioning is based on the principle of thermodynamics. You first make an evaporator, then connect two copper tubes, add some Freon, and then make a compressor and an outdoor unit to dissipate heat and cold. It's done, and it doesn't consume energy. You only need to install one in a room. You don't need one for each person."

Jiang Zihan handed him the notebook with the drawings he had made and told him that he only needed to study how to save energy in the future and not waste his time and energy on other useless things.

The student was very excited and shocked when he got the blueprint. He asked Jiang Zihan, "Teacher? Are you new to our department? I don't think I've seen you before?"

Jiang Zihan smiled and said nothing.

"Brother, you're back." Jiang Zihan had just stood up when a figure came straight to her and held her hand. Originally, a girl came to him and held his hand. Jiang Zihan was frightened and wanted to push her away, but when he heard the familiar voice, he let her hold him.

"Xiao Qian is still so irritable. Look, Xiao Chen is not like you."

Jiang Yan's two precious daughters can be said to be two extremes, one is quiet and the other is noisy, but the relationship between the two sisters is quite good.
