"Why are you so polite, you have helped me a lot, I am still waiting for you to take the time to tutor my English." Cheng Qingyan said with a smile.

"Then it's going to be the end of the New Year...... Duan Yun pondered for a while, and then said: "I will go back to my hometown in the Northeast for the Chinese New Year this year, and it is estimated that I will not be able to come back until after the tenth day of the first lunar month." ”

"Well, it's okay, in fact, I haven't been back to my hometown for many years...... Cheng Qingyan said.

"Your hometown is also from the northeast. Duan Yun asked.

"Aren't we all the same, the old workers in the factory are basically from the northeast, but they may have grown up in Daxing, and they don't seem to miss their hometown much. Cheng Qingyan thought for a moment, and then said: "But I have the impression that the walnuts and hazelnuts in my hometown are very delicious, and when I was a child, I loved to eat these dried fruits when I returned to my hometown, and sometimes I didn't want to eat ...... rice."

"Haha, okay, I'll go back to my hometown this time and bring you something delicious. Duan Yun said with a smile when he heard this.

It seems to be the nature of girls to like to eat snacks, which is similar to the fact that men like to smoke, and it is a pastime anyway.

"Thank you then, I'll give you the money when I get back. Cheng Qingyan's eyes lit up when she heard this.

"It's boring to talk about money, besides, your family cooked for my mother for half a month, and my mother didn't give you a penny......"

"Auntie asked me for money several times, but I didn't. ”

"Isn't this over!" Duan Yun raised his eyebrows, and then said: "Okay, let's not talk about this, next time if you go back to your hometown, you can also help me carry something." ”

"Hmm. Cheng Qingyan nodded, then got up and said, "Then you are busy, let's see you in the evening." ”

"Okay. ”

After Duan Yun finished speaking, Cheng Qingyan turned around and left the office.

After Cheng Qingyan left, Duan Yun tidied up the bookcases in the office again, and moved the bookcases slightly, leaving a space in the corner of the wall that could be used to visit some flower pots and other things in the future.

Duan Yun liked the office that Qin Gang had arranged for him, where Duan Yun could draw and do other work without interference.

Although Duan Yun is now the deputy head of the technical department, Qin Gang did not arrange any tedious work for him, but just let him have time to continue to carry out technical transformation in the factory, and the only important job is to maintain the gear hobbing machine.

Duan Yun left the factory during this time, the gear hobbing machine he modified has been running stably, the processing efficiency of the gear has been greatly improved, this machine usually only needs an apprentice to operate, the operation method is also quite simple, but the production efficiency of this gear hobbing machine is already quite seven or eight skilled masters for two or three days of work, and the pass rate is also amazing, except for the occasional workpiece damage caused by the wear and replacement of the cutter head, the pass rate has always been 100%!

It is precisely because of this that when Qin Gang talked to Duan Yun just now, he hoped that he could modify a few more such machines, but in the end, Duan Yun shirked it because he had no extra chips, and Qin Gang didn't know anything about chip integrated circuits, so he could only give up.

In fact, Duan Yun still has some chips in stock, and it is no problem to make a few more CNC gear hobbing machines, but Duan Yun has his own ideas.

In Duan Yun's opinion, he must have a strong hole card in his hand that can guarantee his position in the factory.

Duan Yun can completely modify several gear hobbing machines in one go, so that the gear production efficiency in the factory can be improved to a higher level, but if Duan Yun really does this, then his importance in the factory in the future will not be so great.

After all, this is a state-owned enterprise, not a private enterprise that Duan Yun can fully control, Duan Yun has made such a big contribution to the factory at once, and several factory leaders will definitely take Duan Yun's success to add glory to their political achievements, but Duan Yun will at most get another honor such as a model worker or an advanced individual, but these rewards are basically of no use to Duan Yun now.

In addition, after there are enough gear hobbing machines in the factory, Duan Yun is not so important in the eyes of the leaders.

With the current 'urine' of the leaders of the Red Star Gear Factory, they must have done the things of crossing the river and demolishing the bridge, and cooking rabbits and dead dogs, even if these leaders have a conscience, but who will hold a person who has lost its use value in the sky?

If it is really because there are more gear hobbing machines, the bonuses of these milling machine technicians will be greatly reduced, and these workers will secretly destroy Duan Yun's machine if they are in a hurry, and then the maintenance alone will be enough for him to have a big head, which is a more realistic problem.

Therefore, Duan Yun can contribute to the factory in his position, but he can't 'feed' the factory too much, so that the factory still needs him, just maintain a delicate balance, and fight with these old guys in the factory, you must have reservations......

......

After getting off work at noon, Cheng Changlin returned home with a gloomy face.

Yang Xiufang recently got off work early every day, and at the end of the year, the unit was busy buying New Year's goods, and everyone's hearts were not at work, so Yang Xiufang saw that the unit was fine, so she went home early from work.

By the time her husband and daughter came back from work, Yang Xiufang had already prepared a hearty meal.

Cheng Changlin threw the bag in his hand on the sofa and sat at the dining table, looking at the food on the table, but he didn't seem to have much appetite.

"Mom!" At this time, the door opened, and Cheng Qingyan also returned home from work.

"Why did you come back, is the unit busy?" Yang Xiufang asked her daughter.

"I'm not busy, I just went to the workshop to go around, the new list structure in the factory is a bit complicated, I'm afraid that the workers don't follow the process, so I went to see. Cheng Qingyan replied casually, took off her coat and hung it on the hanger, and saw her father sitting at the dining table in a daze, her face was a little unsightly, so she asked, "Dad, what's wrong with you, why don't you eat?"

"You eat yours, leave me alone. Cheng Changlin replied impatiently.

"Lao Cheng, what's wrong with you? Is there something wrong with the unit? Did you quarrel with the factory director and secretary?" Yang Xiufang also noticed that her husband's expression was wrong at this time, and then asked.

"What do I have to quarrel with the factory director and secretary? Today I was so angry with Duan Yun's little rabbit cub that I ......," Cheng Changlin said angrily.

"Duan Yun?"

As soon as Cheng Changlin's words fell, Yang Xiufang and Cheng Qingyan's mother and daughter were stunned for a moment.

"Then why?" Yang Xiufang asked after a moment.

In Yang Xiufang's impression, Duan Yun has always been a good child, even if her husband spoke coldly to him for a while, Duan Yun still behaved very sensibly and had a very good temper.
