In the next two weeks, Duan Yun's days were peaceful.

After Duan Yun went to work every day to go around the department, he went to the workshop to check the operation of the gear hobbing machine.

Any mature technical improvements cannot be achieved overnight, and some design flaws and problems need to be discovered when the machine is running for a long time.

After the machine has been running for a period of time, some of the modified workpieces have begun to have various small problems, some of them are seriously worn, and some are running at too high temperature, and the workpiece has undergone some slight deformation, which affects the machining accuracy.

However, these are all within the control of Duan Yun, and only need to make some small improvements occasionally, and then replace the problematic artifact.

After several improvements, the operation of this gear hobbing machine designed by Duan Yun finally began to stabilize, and there have been no problems for nearly a week.

Compared with the affairs of the unit, Duan Yun's biggest headache now is the affairs of the family.

The hospital informed Duan Yun as early as a week ago that his mother's physical examination was normal, and the wound had almost healed, and she could be discharged home.

But Gao Xiuzhi is now hospitalized as if she is addicted, but she stays in the hospital and doesn't leave, waiting for Cheng Qingyan to bring her food every day.

Duan Yun naturally knew the old lady's thoughts, but if her mother didn't leave, Duan Yun, who was a son, couldn't drag him out of the hospital, and her mother made it clear that she didn't like to eat the food cooked by herself and her sister Duan Fang, and she made it clear that she wanted Cheng Qingyan to deliver the food.

Although Duan Yun's thickness has always been comparable to the city wall, he feels a little reluctant to always let Cheng Qingyan bring food to him, after all, Cheng Qingyan has to go to work every day, and he has to go to the hospital to deliver food to his mother after work, and from beginning to end, Duan Yun didn't give Cheng Qingyan a penny of food money!

In fact, Duan Yun also discussed with Cheng Qingyan to give her family some food, but Cheng Qingyan directly refused.

Since learning that Duan Yun refused the order of the Light Industry Bureau and continued to stay in the factory, Cheng Qingyan seemed very happy, and Cheng Changlin's attitude towards Duan Yun has also changed one hundred and eighty degrees, every day Cheng Qingyan's mother Yang Xiufang will get off work a little early, and when she returns home, she will start to cook porridge, and the dishes are also made in different ways, Cheng Changlin will settle her daughter every day and send the meals to the hospital early.

Favors are the hardest things to return.

In fact, Duan Yun has been riding a motorcycle to send Cheng Qingyan to and from school before, and he has never asked for a penny of fuel money, and he has also helped Cheng Changlin quickly master the operation and maintenance methods of the new machine, which has made the Cheng family feel that they owe Duan Yun a lot of favors, so this time to send food to Duan Yun's mother, the Cheng family is naturally willing.

Her mother has been staying in the hospital, but Duan Yun has to leave the unit temporarily.

The German equipment has been shipped to China by sea, and the customs has released it, and it will be shipped to Daxing City in two or three days.

Knowing that the equipment was about to be shipped, Daxing Automobile Factory No. 1 had set up an equipment transformation office, with Chief Engineer Wang as the general person in charge of the transformation office, and Duan Yun also had to enter this transformation office to assist Chief Engineer Wang.

After Qin Gang, the factory director, got Ruiyang's call, he immediately notified Duan Yun and asked him to wait at the factory gate tomorrow morning.

Although the gear factory now also needs Duan Yun to often go to the workshop to maintain the gear hobbing machine, but after all, the city bureau is a superior unit, and it is also a tradition among brother units to arrange for him to go to other factories to help.

The next day, Duan Yun got up early in the morning, came to the factory gate and waited for a long time, when he saw a car slowly driving over.

This Daxing brand car was brought by Daxing Automobile No. 1 Factory to pick up Duan Yun.

In Daxing City, only the Mining Bureau, 3528 and 616 such large factories have cars specially equipped with factory leaders, and even if it is a gear factory with such good efficiency, the factory director secretary can only ride a bicycle to the city bureau for a meeting.

The Daxing Automobile Factory itself is a unit that produces cars, so it is a matter of course that the factory leaders are equipped with cars, and they can publicize the products of the factory by the way when they go out to talk about business or go to the city for meetings.

In the past two years, Daxing Automobile Factory is mainly for some domestic public security and government departments to produce light cars, is directly from the domestic purchase of four major assemblies (engine, transmission, front axle, rear axle) and then assembled, the quality is not much, but also quite fuel-intensive, the life of the car is a little longer, the engine is like asthma, vibration and sound are very large, but even so, this is still one of the few domestic car brands.

"Xiao Duan!" After the car door opened, a tall middle-aged man wearing a windbreaker ****** walked out of it, it was Chief Engineer Wang who went abroad with Duan Yun last time.

"Chief Engineer Wang!" Seeing this, Duan Yun immediately stepped forward and shook hands with Liu Feng with a smile.

The installation and testing of major equipment in a factory like this is generally led by the chief engineer of the factory, and it will not be easily touched by outsiders.

But this time the situation is different, the installation of this part of the imported equipment is guided by the Germans, Duan Yun can understand the technology in foreign languages, he has to undertake the liaison work with foreign engineering personnel, but also to communicate and negotiate with the Germans in some technical matters, after all, the original equipment drawings were translated by him, and Chief Engineer Liu's understanding of the new equipment is far less than Duan Yun, so it is also necessary to rely on Duan Yun technically.

This is a relatively embarrassing thing for Chief Engineer Wang, he has worked in the automobile factory for more than ten years, but he still needs to consult Duan Yun, a young man from another factory, which is obviously a big thing.

Moreover, Ruiyang, director of the municipal bureau, also attaches great importance to the transformation of this new equipment, and repeatedly demands that there must be no problems on the side of the automobile factory, and if a major accident really occurs, several factory leaders of the Daxing automobile factory will be strictly held accountable.

Therefore, compared with the success of this new equipment transformation, Chief Engineer Wang felt that his face was not worth mentioning at all, so he sincerely sought Duan Yun to help in the factory this time.

After a few pleasantries, the two got into the car together.

Closing the door, Duan Yun suddenly felt the warmth in the carriage.

This is the first time Duan Yun has taken a car since he was reborn in this era.

This made Duan Yun feel a little emotional.

Less than half a year after his rebirth, Duan Yun's means of transportation finally evolved from two wheels to three wheels, and now he finally got into a four-wheeled car......
