Siheyuan works as a nanny for Shazhu

After saying this, Zhang Jiacheng took out a manual from his bag and said, "You don't need to come here specifically to help. Just take a look at it when you have time. Please help me correct any mistakes. I won't tell anyone. Even if there are any problems, it's none of your business."

Jiang Feng looked at the man in front of him with sweat all over his face, pretending to beg for help. He sighed, took the manual and said to Zhang Jiacheng, "Engineer Zhang, I believe you know why I disagree with the factory director and the technical department. I told you the truth. I can translate the manual. You can come and get it when you get off work. But I still said what I want to do. I want to borrow the power of the technical department."

After saying these words, Jiang Feng looked at Zhang Jiacheng who was standing there in a daze, and stopped talking. He finished the cigarette in his hand and went to the workshop. He walked around for the whole afternoon, corrected all the translation errors in the manual, checked it carefully again, and put it in his bag.

When it was almost time to get off work, Zhang Jiacheng came over again. Jiang Feng returned the manual to him and said to him, "Engineer Zhang, if you don't want to involve the technical department, don't come to me again in the future."

Zhang Jiacheng also called his master in the afternoon and told him what Jiang Feng said. His master said that people who work in technology hate these kinds of roundabout things the most. Since the other party is unwilling, then forget it. If you mix the technical department into it, you may not get the desired result in the end.

Zhang Jiacheng knew what his master meant and was unwilling to show up. After all, the person opposite him was also an eighth-level electrician. After hearing what Jiang Feng said, Zhang Jiacheng moved his mouth but did not speak. Seeing Zhang Jiacheng like this, Jiang Feng just smiled, turned around and left, leaving Zhang Jiacheng standing there with the instruction manual.

It seems that the time is almost up, and it is time for Jiang Feng to get off work. Now that he is in the workshop every day, he doesn't need to check after get off work. The bait has been thrown out, so it depends on whether he can catch a big fish.

Zhang Jiacheng took the instruction manual and walked towards the workshop. He found a machine of the same model and compared it with the instruction manual. He wanted to dismantle the machine right away and perform maintenance according to the instructions. However, everyone in the factory had already gone off work and only the workshop director was left. Seeing that Zhang was still there and waiting for him, Zhang Jiacheng suppressed his excitement and had to leave work first.

The next morning, Zhang Jiacheng came with people from the technical department, told the workshop director, and stopped the machine. Zhang Jiacheng took the instruction manual and directed a level six master in the workshop to dismantle several parts of the machine. He watched Xiao Liu oil it, clean it, and remove the oil stains, and finally reinstall it.

The machine was started up again, and the level 6 fitter felt the difference at once: the sound was quieter and there was no noise. He took a workpiece aside and started to work on it. After he finished, he grabbed the workshop director and wouldn't let go, requiring the entire workshop to stop work and have all the machines maintained. Not only was it smooth to use and the cutting was powerful, but the precision was also higher.

This time, Engineer Zhang learned his lesson and did not go to Workshop 1. He is now in Workshop 4 for fitters. The workshop director is Yang Daming. Although the level 6 fitter in the workshop spoke, he took the workpiece and did it himself with half-belief. He is only a level 5 fitter himself. After finishing, he was also very excited. He hadn't felt his skills improved for many years and felt that he could even take the level 6 exam.

He put down the workpiece, said to a few people, "Wait here," and went in to make a phone call. After waiting for about ten minutes, Director Yang and the deputy director in charge of safety arrived. They watched a fourth-level fitter easily process the workpiece, and the precision was higher than before. Director Yang waved his hand, and all the fitters above level four in the workshop came over.

With Zhang in charge, they dismantled another machine. This time they did it more slowly, explaining as they dismantled it, striving to make all the mid-level and senior fitters in the workshop learn it. This time it took more than two hours, and basically everyone knew how to do it. After the machine was assembled, under the command of Director Yang, the only seventh-level fitter in the workshop stepped forward, picked up the workpiece and started processing it. People around were watching, not daring to breathe. After the processing was completed, they took the measuring tools to measure, and the seventh-level fitter said, "The workpiece is qualified, and the precision has reached an excellent level."

Zhang Jiacheng stepped forward to grab the workpiece, measured it, and said to the seventh-level fitter: "Master Wang, when you processed this kind of workpiece before, what was the yield rate? What was the good and inferior rate?"

Master Wang said: "The qualified rate of finished products can reach 70%, and the good rate is only 10%, but it is not certain now. I just felt very good. If I am not tired, I am sure that the qualified rate will reach 80%. The good rate will also increase, but how much it will increase depends on the actual data."

Factory Director Yang listened to the data and realized that with so many workers and equipment, the output value of the entire factory would increase by how much per day, not to mention 10% improvement in the pass rate. Even if it was 5%, how much would the output value of the entire factory increase in a year? He immediately said to the workshop director, "Daming, all machines of the same model will be shut down. Your workshop will be used as a pilot. The master who just saw it will be responsible for maintenance. All workers above level one must come to learn and complete the maintenance of the machines of this type in workshop first."

After hearing the factory director's order, Yang Daming immediately arranged for the team leaders to notify the shutdown. Seeing that the workshop director had gone to work, Factory Director Yang pulled Zhang Jiacheng aside to talk. Zhang Jiacheng hadn't figured out what Jiang Feng said yet, but just said that he wanted to give it a try and do some maintenance on the machinery.

At this time, Secretary Li came over and pulled Director Yang and whispered a few words in his ear. Director Yang looked at the time and saw that everyone was having lunch, so he asked Secretary Li to notify the workshop director. He took Zhang Jiacheng and said he would go eat first and come back to check later.

But Zhang Jiacheng didn't want to do that. It was during the time when he was keeping an eye on things, so how could he have time to eat? He told Director Yang, and went to inspect with several people from the technical department. Director Yang shook his head, told Deputy Director Wang to be careful, and asked Secretary Li to go to the canteen to tell them. Director Yang saw that the time was up, so he arranged for a dozen apprentices to take their lunch boxes to the canteen to get meals, and all the money was recorded, and Director Yang would go and pay and get the receipts later.

When the apprentices brought back their lunch, the workshop was still busy. However, one-third of the maintenance of the same type of machinery had been completed. Director Yang saw this and arranged for some people to eat first, taking turns to eat, and then continue working after eating. By about three o'clock in the afternoon, all the machinery in the workshop had been maintained. Director Yang came during the afternoon work. Director Yang asked for instructions from Director Yang and Deputy Director Wang, and they both nodded. Director Yang waved his hand, and the roar of the workshop rang out.

The workers in the workshop also clapped happily. In the past, they did not dare to dismantle them at all. They would only dismantle those that really could not run. However, they could not understand the instructions. They only knew that the parts were broken, but they did not know where they were broken, and they did not know how to dismantle them. They would go to Big Brother to arrange for someone to deal with them. Now with maintenance, parts that used to break in three years can now at least be used for four to five years.

When the first worker finished making the workpiece, Director Yang came forward to take a look and shouted, "Qualified." Then the workshop was filled with voices shouting "Qualified". Director Yang suppressed his excitement and called Zhang Gong and Director Yang over: "It can only be used normally now. This afternoon, you have to keep an eye on it. I want to know how much the qualified rate has increased compared to the past? How much has the excellent rate increased?"

Director Yang said excitedly: "I guarantee that the task will be completed."

Zhang Jiacheng just nodded. Amid the roar of machinery, it was time to get off work. Director Yang compiled the data, and Zhang Jiacheng's face flushed with excitement. The two of them walked towards the factory director's office together. Director Yang was still waiting in the office at this time. Seeing the two of them coming, he stood up and asked them to sit down. Secretary Li also poured them some tea.

Director Yang said hurriedly, "Director, please take a look. This is the data from this afternoon, and this is the data from yesterday afternoon. By comparison, the qualified rate has increased by 12%, the excellent rate has increased by 4%, and no machine broke down this afternoon. All machines can be used normally."

Director Yang picked up the record sheet and took a look. The comparison between the two days was clear at a glance. The statistical data was based on the same people operating the machine, and the time was reduced by one hour. The number of finished products increased, and the scrap rate decreased. Director Yang slapped the table excitedly and said, "Okay, Engineer Zhang, take a look at these data and see if you can arrange for maintenance work to be carried out throughout the factory."

Zhang Jiacheng did not look at the data, he had already looked at it, and said to Director Yang: "We can arrange for some middle and senior masters from Workshop 4 to go to each workshop for guidance. It is estimated that the maintenance work of the entire factory can be completed within two days, but this requires the support of Workshop 4."

Director Yang knew that if he went to other workshops to give instructions, his own workshop would have to stop working. Every month, each workshop would be evaluated. Stopping work to give instructions to other workshops would definitely affect the tasks of his own workshop. After thinking about it, he said to Director Yang, "Old Yang, just do as Engineer Zhang said. See how many people you can transfer from your workshop. I'll have a meeting tomorrow morning. Your workshop will be the first in this month's workshop evaluation."

When Director Yang heard what the factory director said, he was of course willing to do it. He spent two days to change the first one and immediately stood up and said, "Don't worry, factory director, I will arrange it tomorrow morning and wait for your notification."

Director Yang nodded and looked at the two of them. Zhang Jiacheng looked at Director Yang. Yang Daming understood and said to the two of them, "Then I'll leave first. I still have to go back to the workshop to check."

Director Yang nodded, watched Yang Daming walk out, and said to Zhang Jiacheng, "Engineer Zhang, do you have anything else to do?"

Zhang Jiacheng looked hesitant, and Director Yang noticed it. He encouraged him and said, "Engineer Zhang, if you have anything to say, just let me know. As long as it's beneficial to production, just bring it up."

After hearing what Director Yang said, Zhang Jiacheng also made up his mind. He took out a stack of papers from his bag, put them on the table, and said to Director Yang: "This is the manual for today's batch of machinery. I did the maintenance according to the instructions above. Director, you should know why I didn't dare to do maintenance before. You will know after reading this."
