On Friday night, Duan Yun got off work more than an hour early, then went to the city to buy some good cigarettes and wine, and came to Cheng Qingyan's house.

Before Cheng Qingyan was officially married, Duan Yun had to treat the people of his family as ancestors.

Every time he goes to Cheng's house for dinner, Duan Yun's hands will never go empty, good cigarettes and good alcohol are the most basic, in addition to bringing some snacks to Cheng Qingyan.

Now Cheng Qingyan's little face has been fed by Duan Yun is a little fat, but her figure is not out of shape, she is still so slim and beautiful.

"Ah, Xiao Duan, come in!" After hearing the knock on the door and opening the door, Yang Xiufang smiled as Duan Yun entered the house, and after seeing the big bag of things Duan Yun was carrying, he said, "Come on, why do you bring so many things?"

When I was in the main factory before, you and Uncle Cheng had always taken good care of me, so what would it be if I bought something?" Duan Yun said with a smile.

"It's still a small section that can talk, let's go and sit in the house, and the meal will be good in a while." Yang Xiufang said with a smile.

"Xiao Duan is here, come and sit!" Today's Cheng Changlin was unusual, he was very enthusiastic, and after signaling Duan Yun to sit down, he said to Cheng Qingyan: "Xiao Yan, go and pour tea for Duan Yun"

"Hmm. Cheng Qingyan answered, glanced at Duan Yun, picked up the teapot and filled the teacup in front of Duan Yun with water.

"Smoking!" Chen Changlin took out another cigarette at this time and said to Duan Yun.

"I just smoked, so I won't smoke it. Shorter than polite, he refused the cigarettes handed by Cheng Changlin.

"I've been busy at the labor service company lately, right?" asked Cheng Changlin.

"It's ok. ”

"I really opened my eyes last time, I really didn't expect you to manage the big collective so well in just one month, the factory environment is good, and the workers work very hard......" Cheng Changlin paused, and then said: " I have always felt a little strange, how do you make the gears of the car gear, before our factory has also developed the car gearbox for a period of time, but unfortunately the level of technology has not been able to go up, one is the precision, the other is the hardness, in terms of the current equipment level of our factory, it is not up to the standard at all, how did you do it?"

"This ......" Duan Yun hesitated for a moment, and then said: "Actually, the last time I went to the automobile factory as a foreign liaison, I had an exchange with the German engineer who assisted in the assembly line, and he taught me some things about the production of automobile gearboxes. ”

Peers are enemies, and Duan Yun will never reveal the core process secret of producing automobile transmission gears to outsiders, but when facing his future father-in-law, Duan Yun is somewhat embarrassed.

"That's it......" Cheng Changlin nodded, and then asked: "It stands to reason that the equipment on your collective side is not as good as the main factory, two years ago, I studied the production of automobile transmission gears with those technicians in the main factory, but no matter how to improve the process, the processed gear accuracy and other parameters are not qualified, can you tell me the specific technical details of your research gears this time......

After all, Cheng Changlin is also a person who is engaged in technology, and he knows all kinds of processes about agricultural machinery gears and gearboxes, but he has not been able to make automobile gearbox gears, which has become a knot in his heart, and he has been thinking about improving the technological level of the products in the factory in recent years, so he is very curious about what process and method Duan Yun uses to produce automobile transmission gears.

"Actually......" Duan Yun pondered for a while, and then said: "Ordinary technical transformation is not able to make qualified automobile transmission gears, now some of the top international automobile manufacturers are using CNC technology, I have installed a set of integrated circuit boards on the automatic gear hobbing machine and gear grinding machine, with chips and program control, instead of manual operation, the machine error controlled by digital circuits is small, and the processing accuracy is high, which is also the core technology of our factory to produce automobile transmission gears......"

Duan Yun knew that although Cheng Changlin was proficient in machinery, he had serious shortcomings in electronic technology, especially integrated circuit technology, so he definitely didn't understand this.

"Ah......" Sure enough, after hearing Duan Yun say this, Cheng Changlin's face suddenly showed a look of disappointment, he originally wanted to learn something from Duan Yun and then use it in the main factory, but now it seems that even if Duan Yun is willing to teach him sincerely, he can't learn it at all.

"Let's eat!" At this time, Yang Xiufang had already put the freshly prepared meal on the table.

"Eat, eat!" couldn't learn the technique from Duan Yun, and Cheng Changlin simply gave up, after all, it was possible to become a family with Duan Yun in the future, and it didn't matter if Cheng Changlin could learn this technique.

Cheng Changlin was in a very good mood today, and after serving the dinner table, he had to pour wine into the wine glasses of himself and Duan Yuan.

Duan Yun was taken aback when he saw this, no matter how big he dragged it out, Cheng Changlin was his elder and future father-in-law after all, so this detail still had to be paid attention to, so he took the wine bottle from Cheng Changlin's hand, and then respectfully poured it for him.

"Eat vegetables in a small section!" After Yang Xiufang put all the food on the table, she wiped her hand on her apron, and then picked up chopsticks and sandwiched a piece of meat for Duan Yun.

"Thank you, Auntie. ”

"You're welcome to eat at our house in the future. Yang Xiufang said with a smile, and then said: "You still have the ability to be a small section, you can become the manager of a large collective at a young age, and manage the factory so well, now our head factory is talking about you, saying that you have the technology and ability, I also heard that the day before yesterday, you pay wages to the big collective, and the wages of workers are higher than those of the head factory, is it true?"

"In fact, there are only a few masters whose salaries are a little higher, and they do a lot of work, so they should be paid a little higher, and the workers in other positions are a little worse than the main factory...... Duan Yun said.

In fact, the large collective pays wages this time, and the first-line workshop is indeed higher than that of the main factory, but Duan Yun wants to keep a low profile, after all, this is just a large factory-run collective, and if it is too much higher than the main factory company, it will cause a lot of criticism.

"That's also quite remarkable, in the past, the people in our factory shook their heads when they mentioned the big collective, the factory lost money every year, and the workers took a little basic salary, and you were transferred to become a manager, and the big collective immediately made money, in the end, you still have the ability to do it!" Yang Xiufang said with a smile.

Yang Xiufang has always been very optimistic about Duan Yun and can see that he is a young man with a little ability, but this time Duan Yun can turn the big collective into a profit within a month, which is indeed beyond Yang Xiufang's imagination.

Now seeing that Duan Yun has a bright future, and the relationship with his daughter is developing smoothly, Yang Xiufang is also full of joy.
