After the introduction, everyone knew each other, and they were on the same page as me.

Last night, Zhao Ting briefly introduced the situation of the family, a family of 12 people, and 7 people present today.

Old man Zhao, his wife's name is Qian Xiu, and he has only two sons, the eldest Zhao Cheng and the second Zhao Xuan.

Zhao Cheng is Zhao Ting's father, a senior official of a ministry, and his mother Yuan Sibing, who works in the Propaganda Department; The eldest brother, Zhao Xiangdong, is married and works at the Xizhimen Police Station.

Zhao Xuan has three sons and one daughter, and his wife Feng Tongyu, who is a middle-aged beauty just now, works in the Material Bureau; The eldest Zhao Revolution, the head of a military region, the second Zhao Hongjun, the director of the first division of the Ministry of Mechanical and Electrical Engineering, the third Zhao Jiefang, a teacher at the Wudaokou Technical College, and the fourth Zhao Jie, is a policeman at the Dongzhimen Police Station.

After Zhao Jie helped put down the things, she brought three stools and did it together.

Next, it is the performance time of the two middle-aged women, starting from work, and asking how many meals a day they eat. Aunt Zhao Ting's second aunt always asks some embarrassing questions, but fortunately, Li Guocheng is young and old, and he copes with all of them.

The old man and Dad Zhao were very serious throughout the whole process, they didn't interject, and the old lady didn't talk happily.

Half an hour later, the old man obviously lost his patience, stood up and said, Boss, Xiao Li come to the study with me, Zhao Ting, you accompany them to talk.

Li Guocheng nodded to the rest of the people to apologize, and followed into the study, Zhou Jun, who was not counted, was extremely angry in his heart, originally the purpose of coming today was to sabotage Li Guocheng's meeting with his parents and find an opportunity to confess to Zhao Ting, but the current situation is like a blind date meeting. Zhou Jun understood very well that this should be the old man's idea, so now he even hates the old man.

Entering the study, against the wall is a row of bookshelves piled with various books; A desk with a Taishi chair inside and outside the desk, and under the windowsill are old-fashioned radiators wrapped in wooden grilles, on which are placed two pots of unknown flowers. Opposite the desk is a coffee table, the size of a Go chessboard, with a simple sofa on each side of the coffee table.

Li Guocheng bowed politely, the old man first sat on the Taishi chair outside, Zhao's father sat on the sofa in the middle, and after Li Guocheng and the others sat down, they consciously sat on the sofa by the door.

As soon as the three of them sat down, Zhao Ting pushed the door in, and brought 2 cups of tea and the old man's big tea jar with a tray in his hand, Li Guocheng got up to help put the tea jar on the desk, two cups of tea on the coffee table, one of which was put on Zhao's father's hand, Zhao Ting did not help during the whole process, just watched Li Guocheng busy with a smile, and then exited the study and brought it with him.

Li Guocheng only sat on half of the sofa, his upper body straight.

"Actually, we all know your situation, you are young, your ability is not small, I don't know what your plans are in the future?" The old man opened his mouth and asked, the so-called people are old and fine, straight to the point, a little bit of a sense that you have to be careful when you speak.

Li Guocheng had considered it before he came, what could be said and what could not be said.

"At present, my main work is machine tool design, and I am interested in semiconductors, and I am learning on my own, and I hope that the two can be combined in the future."

"Are you talking about Dawn 1966?"

"That was the first version, and now semi-automatic machines are being designed."

"Tell me about it".

"Now the machine tools in our workshop are all manually fed, and we need to bend over for a long time to maintain a movement, which is easy to fatigue; When processing the workpiece, it is necessary to slowly feed the tool with one hand according to experience, and it is easy to damage the knife edge if it is fast, and the efficiency is too low if it is slow. Because most of the machine models are too old, the machining accuracy depends on the feeling in the hands of the master, and it must be the same lathe.

The so-called semi-automatic machine tool is that the master sets the feed speed and distance according to the drawings, and then the subsequent processing is handed over to the lathe, and the machine stops automatically when the preset processing position is reached.

The advantage is that the workers save physical strength, and the machining accuracy is determined by the lathe, which greatly reduces the ability requirements of the processing masters, and makes it easier to form a scale effect."

"What is the machining accuracy of the new machine?"

"The accuracy of Dawning 1966 is 0.05mm, and the design accuracy of semi-automatic machine tools is not less than 0.05mm."

"What is the highest accuracy of the machine tools in your rolling mill at the moment?"

"Level 8 masters can reach 0.1mm based on experience."

The old man was asking the whole time, and at this time, the old man and Zhao's father looked at each other, and they were very surprised by this data.

"Has the Aurora 1966 been mass-produced?"

"At present, we are in internal trial production to verify the drawings and processes to ensure that we have large-scale production capacity."

"Are you ready to produce it yourself?"

"The specific situation is not clear", Li Guocheng did not dare to hearsay, even if Li Huaide said that it may be transferred to the Capital No. 1 Machine Tool Factory.

The old man is more and more interested, as the old revolution for the importance of machine tools is very clear, now it is very difficult to purchase high-precision machine tools from abroad, the country is still in the stage of imitating the big brother, I did not expect the rolling mill to have such a big surprise.

Judging from Zhao's father's serious attitude, he is very interested in the current topic, but because of the old man, he didn't ask questions.

"Tell me about the situation of semi-automatic lathes", the old man continued to ask.

"At present, the drawing design has been completed, the drawings are checked, and the next step is the trial production prototype."

"Are you responsible for all this?"

"Yes".

The old man is now very satisfied, as an old revolutionary, he hates the concept of the door very much, but likes those young people who are useful for the construction of the country.

"Your education is in junior high school, right?" , Zhao's father raised the question he had always wanted to ask out of professional sensitivity.

"Yes", Li Guocheng knew that the main drama was coming.

"Can you tell me where this machine design knowledge comes from?"

Li Guocheng didn't panic at all, and now he has already prepared all kinds of excuses. There are enough mechanically structured books on the shelves at home, and there is also a library as a knowledge base.

"Since I chose a fitter, I wanted to make something, so I preferred to go to the library to read mechanical books, and later went to the scrap yard to buy some of them, and I was born with a strong memory and understanding, so it was relatively easier to learn these."

Dad Zhao turned around and took down a report from the bookshelf, more than 100 pages, and handed it to Li Guocheng.

"Let's see what you're capable of."

Li Guocheng nodded, took it, and looked at it for about half an hour. If reading and memorizing with all your might, up to 10 minutes. Then he looked up and handed it to Zhao's father.

The old man and Zhao's father were a little unbelievable, how could this be.

"Do you remember them all?" Zhao's father grabbed the right to speak.

"Yes".

Then Zhao's father rummaged through the contents of the report, tested it in various ways, and found that everything was correct.

"It turns out that geniuses really exist", the old man looked at Li Guocheng and said with emotion, and Zhao's father nodded in agreement.

"I've decided on this marriage, you can find a suitable person to propose", the old man made a decision on the spot.

Dad Zhao can only nod now.

When the three of them walked out of the study, the living room was a different scene.

Zhou Junzheng looked at Zhao Ting proudly, Zhao Ting was expressionless, Zhao's mother and second aunt were trying their best to persuade something. The old lady also comforted Zhao Jie in a low voice with a blank face, but Zhao Jie seemed to have cried.

Seeing Liu Guocheng come out, Zhao's mother and second aunt didn't have a good face, but they didn't speak tacitly.

Zhao Ting got up and walked to Li Guocheng's side, saluted the old man and said, "Grandpa, we've stayed long enough, let's go back first", and then turned to everyone, "Grandma, Dad, Mom, Second Aunt, let's go first", and took Li Guocheng's hand and was about to leave.

The old man was more transparent, and without waiting for others to speak, he immediately said, "What are you going to do?" Eat and go! Then he looked at everyone and said, "I agreed to the marriage of Ting'er and Li Guocheng!" ”

Seeing that Zhao's mother was about to speak, Zhao's father hurriedly stopped and gave a look, although Zhao's mother was puzzled, she didn't speak again.

Zhao Ting's second aunt didn't see the state clearly and said, "Dad... ”

Without waiting for her to continue, the old man stared at her and interrupted: "Ting'er's affairs, you don't care, and you are not qualified to care."

Looking at the old man's demeanor, in the end, the second aunt didn't dare to speak again.

Zhao Jie immediately ran to Zhao Ting's side, jumped up with her arms around her arms, and seemed to be happier than Zhao Ting. Zhao Ting, who had always remained calm, threw herself into her grandfather's arms and cried at this time. Li Guocheng stepped forward and patted Zhao Ting on the shoulder to show comfort.

Seeing such a result, Zhou Jun's face was a little distorted, staring at Li Guocheng fiercely, and he couldn't wait to rush up and fight.

Feng Tongyu couldn't do anything, so he found an excuse to leave the small building with Zhou Jun and the reluctant Zhao Jie.
