On Tuesday night, Duan Yun and Cheng Qingyan went to class at the night university as usual.

The classmates in the class already knew about Duan Yun's going abroad, and as soon as they entered the classroom, they immediately surrounded him and asked him about his experience of going abroad this time.

Duan Yun could see that the classmates in the class were still very envious of him being able to go abroad, but Duan Yun didn't bring any gifts to the classmates in the class this time, after all, there were a lot of classmates.

When he went abroad last week, Duan Yun pulled down several classes, but Cheng Qingyan lent Duan Yun the notes of these courses, and during self-study, Cheng Qingyan also helped Duan Yun with a simple tutoring.

Now Duan Yun and Cheng Qingyan can be regarded as helping each other, Duan Yun taught him English, and Cheng Qingyan discussed the night college course with him, and both of them are making progress together.

After school in the evening, Duan Yun sent Cheng Qingyan to her doorstep.

"By the way, Duan Yun, you come to my house for dinner tomorrow night, the day before yesterday you gave me so many books, and my mother told me a meal, saying that I shouldn't take other people's things for nothing, so I want to call you to my house for dinner tomorrow night. After Cheng Qingyan got out of the car, she said to Duan Yun.

"Going to your house for dinner?" Duan Yun was stunned for a moment when he heard this, and then said with a smile: "I think forget it, in fact, those books are not worth a few dollars, so I don't need ......."

Duan Yun really didn't want to go to Cheng Qingyan's house, the main reason was that he didn't want to see Cheng Changlin's face.

Speaking of which, Duan Yun felt that he had not offended him, but Cheng Changlin had always been unkind to him, usually when he was in the unit, he always kept a straight face to himself when the two met, and some time ago, when Yun sent Cheng Qingyan to school, he was still staring at himself in the corridor like a thief, and he had no good face.

However, Duan Yun didn't care about this, although he worked in the technical department, he actually had very little contact with Cheng Changlin, so nothing else unpleasant happened.

As for Cheng Qingyan's mother, she was still good to Duan Yun, and she also sewed a thread glove for Duan Yun before, and Duan Yun still carried it on her hand now, which was quite warm.

"That's not good!" Cheng Qingyan shook her head and said, "My mother said that I must call you over." ”

"This ......"

"Letting you eat is not letting you work, you just bring your mouth over, talk less and eat more, don't be afraid, my dad can't eat you again." Cheng Qingyan knew that her father was usually not kind enough to Duan Yun, and said with a smile.

"Okay. Duan Yun nodded when he heard this.

"Goodbye!" Cheng Qingyan smiled and waved her hand at Duan Yun, turned around and left......

......

The next day, after Duan Yun came to the unit, he took the drawings and went straight to each workshop.

In recent days, Duan Yun's work attitude has really impressed his colleagues in the department, Duan Yun was basically messing around at work before, sometimes coming to report at eight o'clock in the morning, and when it came to about nine o'clock, he basically couldn't find anyone.

But since returning from this trip, Duan Yun has become a model worker in the department, the first to arrive at the unit every day, and after cleaning, he will take the drawings to the workshop, and his work attitude has been completely new.

It's just that what those staff members don't know is that Duan Yun did this for his reasons.

Considering that Zhao Dongsheng was retiring at the end of the year, Duan Yun wanted to throw the hole cards in his hand before he left, and then get the opportunity to be promoted.

Although Duan Yun performed well as a translator in the process of going abroad this time and was praised by his superiors, and Zhao Dongsheng had promised to help him before he retired, if he wanted to get a better promotion in the factory, Duan Yun must have a good contribution, and only in this way can he convince the public!

Therefore, Duan Yun attaches great importance to the modification of the gear hobbing machine this time, and there is some pressure on him, and this is also the price he must pay if he wants to get promotion and rights.

Today, the workpiece has been basically all processed, Duan Yun came to a workshop, and Wang Qiang, the director of the workshop, arranged several masters in the maintenance class to cooperate with Duan Yun and began to carry out a comprehensive modification of the milling machine.

The solution of Duanyun modification this time is much more complicated than the previous modification of automatic lathes, and there are as many as 170 mechanical workpieces for modification alone, which is three times more than the workpieces used in the last modification of the lathe!

The modification scheme is complex and there are many workpieces installed, so it naturally takes some effort, so Duan Yun and several masters of the maintenance class of the first workshop began to disassemble the machine shell in the morning, and did not go home after working overtime at noon, and worked until more than six o'clock in the afternoon, and the machine was basically completed.

Duan Yun planned to leave the rest of the circuit board and wiring part until tomorrow morning to assemble it himself, so after giving the master present a circle of smoke, he left the workshop.

At this time, it was already past the end of work time, and after a tiring day, Duan Yun planned to go home for dinner, but when he was halfway through the ride, he suddenly remembered that he was going to Cheng Qingyan's house for dinner tonight, so he hurriedly turned the handlebar and rode towards Cheng Qingyan's house......

At the same time, Cheng Qingyan and her mother were busy making dinner.

In fact, in the afternoon, Cheng Qingyan's mother Yang Xiufang had already asked for leave in the factory and went to the market early to buy vegetables to prepare for today's dinner.

However, there are more dishes to be made today, there are fish and meat, especially hairtail, which is more troublesome to deal with, and there are also various cold dishes to stir-fry, so it took a lot of time.

Cheng Qingyan often helps her mother cook at home, although her cooking skills are not very high, but it is still very easy to make a table of home-cooked food.

"What time is it, why hasn't that kid come over yet?" Cheng Changlin, who was standing on the kitchen veranda smoking a cigarette, glanced at his watch and said in a somewhat impatient tone.

In fact, inviting Duan Yun to his home for dinner, Cheng Changlin was against it at first, he didn't have a good impression of Duan Yun, so he didn't want Duan Yun to come to his house.

And although Duan Yun has always been interested in sending his daughter to school at night at night, rain or shine, in Cheng Changlin's opinion, Duan Yun's kid is too scheming, obviously he has other plans, and Cheng Changlin is the chief engineer in the factory, and he is usually used to seeing people who pat him on the back and beg him to do things, so he naturally classifies Duan Yun into that category of people.

Cheng Changlin has always liked the kind of honest and studious young people, but he felt that Duan Yun was a bit too young and vigorous, with a lot of flowers, and he gradually mixed up by patting the secretary's ass, so he didn't like him very much.

"Xiaoyan, have you talked to Xiao Duan, he knows that he is going to come to our house for dinner today. Yang Xiufang, who was frying hairtail, asked her daughter.

"I told him yesterday. Cheng Qingyan put the cut Songhua eggs on a small plate and said, "Duan Yun was in the workshop this morning, and he has been busy in the past two days, so he may come over later......"

"What is there to do as a little technician?" Cheng Changlin extinguished the cigarette butt in his hand and said with a disdainful face: "Isn't this time going out of the country?
