The Boss of Yan's Family in Siheyuan

Yan Jiecheng really knows this person. According to Yan Jiecheng’s knowledge, he only knows one word, “niu.”

In terms of past experiences these days, there are too many big names not to talk about.

Let’s just say that he later worked as the boss of General Iron and Steel Co., Ltd. for twenty years, which is a bit scary.

This is a perfect golden thigh.

This golden thigh is currently working as a parent official in Beijing.

Don't be too awesome at all.

Jin Tida and Luo Gong exchanged pleasantries while walking, and after a while they arrived at the living room.

At this time, there was a woman in her fifties and a girl in her twenties in the hall.

The girl has two pigtails and looks very simple.

Those two braids are thick and black, which is very interesting at first sight.

When this girl saw Yan Jiecheng for the first time, she blushed and felt a little overwhelmed.

Yan Jiecheng took a look in surprise. How simple is a girl from such a big cadre family these days? It's a bit like Qin Jingru coming to the city.

Yan Jiecheng felt that this girl was not normal and did not seem to come from such a family.

So he just said hello to the aunt and nodded to the girl without paying too much attention.

At this moment, Jin Tachi introduced everyone. He only introduced the woman in her fifties as his wife, but did not mention the girl.

Only now did Yan Jiecheng pretend to know Jin Thigh’s name.

Just when Yan Jiecheng was confused, Aunt Chang, the wife of Jin Thigh, said: "Cuihua, prepare some tea for you, Grandpa Luo."

Yan Jiecheng nodded silently.

After everyone sat down, Jin Tida Changtu asked his wife: "Why can't you see Kexin? Hurry up and ask her to come and play with Xiao Yan. They young people have something to talk about together."

Mrs. Chang said with a troubled face: "Mr. Luo, Xiao Yan, you don't know that our daughter spends all her time on that broken machine, and she studied it again today, but I couldn't persuade her.

”

Because Mr. Luo knew about Chang Kexin, he smiled and said: "That girl is a top student in the radio department of Huaqing University. Isn't it normal that she likes to study those things?"

Seeing this, Chang Tu said to Yan Jiecheng: "Xiao Yan, this girl in my family was born in 1942 just like you. She is now a senior. You guys should get in touch first."

After saying that, he asked Mrs. Chang to take Yan Jiecheng to the second floor.

He stopped at the door of a room, knocked on the door and said: "Kexin, Xiao Yan, whom Mom told you yesterday, is here. I brought him to you. You two can sit in the room and chat for a while."

After a while, the door opened.

What caught Yan Jiecheng's eyes was a short-haired girl with fair skin, wearing a pair of glasses and holding a small tweezers in her hand.

The first impression that comes to people is that she is generous. You can tell without looking at her that she is the type that Yan Jiecheng likes.

She also looked at Yan Jiecheng, and then called him in.

When Mrs. Chang saw this, she stopped disturbing her.

There were only two people left in the room, and Yan Jiecheng felt a little embarrassed. How could this girl be twenty years old and still have a face of 14 or 15 years old?

Chang Ke was delighted and generous and poured a glass of water for Yan Jiecheng.

He stared at Yan Jiecheng again, nodded after reading it, and said, "He looks quite upright."

After saying that, he ignored Yan Jiecheng and continued to study the pile of wires on the table.

As the saying goes, a serious girl is so beautiful. This girl likes to talk about things on the table.

Yan Jiecheng took a sip of water and felt that the distance was a bit far and he couldn't communicate well, so he looked next to the girl.

After a while, Chang Kexin disassembled the circuit again and tested the material with a multimeter.

I assembled it again, but still didn't achieve the experimental results, so I thought hard about it.

Seeing this, Yan Jiecheng raised the corners of his mouth and said softly: "There is something wrong with your circuit design itself.

伱This kind of circuit is a kind of discrete signal transmission and processing, using binary as the principle to realize the logic operation and operation of digital signals.

It should be composed of the most basic AND gate circuit, OR gate circuit and NOT gate circuit. Its output value only depends on the current value of its input variable and has nothing to do with the past value of the input variable.

The result you want here is yes or no, but in the end you introduce an OR gate circuit.

So the result is definitely uncertain."

After hearing this, Chang Kexin looked at Yan Jiecheng with surprise and said, "Yeah, why didn't I think of that?

Do you still understand this? Didn’t my dad say you were a road builder?"

After Yan Jiecheng heard this, he felt like fuck.

This father-in-law is unjust.

Although in the final analysis, we are indeed a road builder. But after all, we are also a teacher and the youngest deputy director in the department.

Yan Jiefang said nonchalantly: "I don't understand, I just know some basic logic circuits."

Chang Kexin became interested after hearing this.

You must know that logic circuits are cutting-edge technology, but road construction is actually said to be basic.

This person shouldn't be simple. Think about it, his parents can't really introduce him to a road builder.

Chang Kexin pestered Yan Jiecheng to ask questions about logic circuits.

Yan Jiecheng really knows a little bit about this thing.

I saw it when I was bragging to people on the Internet in my previous life.

When asked by Chang Kexin, he had no choice but to explain the principle.

What is combinational logic and sequential logic?

Just this little thing fooled the little girl into being stunned.

What Yan Jiecheng didn't know was that the semiconductor industry was upgrading at a very fast pace. Although what he said was considered by later generations to be very basic electrical knowledge.

But it is still very advanced in this era. It is of great help to the development of medium and large integrated circuits.

After listening to Yan Jiecheng's explanation, Chang Kexin stretched out her hand and said with a serious face: "Let me meet you formally. My name is Chang Kexin. I am a senior student in the Radio Department of Huaqing University."

Yan Jiecheng smiled, held Chang Kexin's hand, and said, "Yan Jiecheng, Mr. Tie builds roads."

"Hee hee, you are such a bad person, and you lied to me that you were a road builder." Chang Kexin said.

Yan Jiecheng said: "We are building railways in the Railway Administration, but we are not building roads."

Chang Kexin did not dwell on this point and asked curiously: "Then how do you know so much?"

Yan Jiefang did not answer her words, but casually took a book from the bookshelf in Chang Kexin's room and flipped through it.

He handed the book to Chang Kexin and said, "Read it, but don't blink."

After saying that, Yan Jiecheng began to recite.

Chang Kexin looked surprised. After Yan Jiecheng recited it for more than ten minutes, he said: "The ancients are honest and honest. There are really people in this world who have a photographic memory."

In this way, the two of them talked about the rise of history, art, architecture, and industry in the room.

After a while, Chang Kexin looked at Yan Jiecheng with eyes filled with admiration.

In the living room downstairs, Chang Tu smiled and said to Luo Gong: "This boy is not simple. My daughter has always been very high-minded. She has always looked down on the young talents from Huaqing University. She didn't expect that this boy

Yan actually chatted with her for so long."

Luo Gong said with a smile: "We are similar in age and both have outstanding talents, so we are naturally attracted to each other."

After Chang Tu heard this, he smiled and said: "Yes."
