Siheyuan: My wife is Xu Huizhen

After being shocked, Xu Xiaomei realized that she had been too abrupt and her pretty face turned red with embarrassment.

Feeling extremely ashamed, he quickly let go of the hug, took two steps back, lowered his head, picked up the dishes beside him, turned around and ran out.

He Yuzhu was also a little stunned. This was too sudden. He hadn't even thought about whether to make a move on Xu Xiaomei, but she already had it in her mouth?

However, since the person had already left, He Yuzhu did not think much about it. The most important thing now was to confirm the performance of the lathe.

Then they started making parts for testing. As the test progressed, He Yuzhu's brows furrowed.

The situation was a little different from what I had imagined. The lathe was developed successfully, but only half successful.

The newly made lathe can produce parts, but the precision does not meet He Yuzhu's requirements and it feels like a semi-finished product.

He Yuzhu made three parts in a row, and the results were the same, which shows that it was not an isolated phenomenon, but that there was a problem with the machine itself.

After washing the dishes, Xu Xiaomei came to the door of the small warehouse, coughed, and then asked without coming in:

"What's wrong? Didn't you just say you were done?"

He Yuzhu sighed and said, "The lathe can be used, but it is a little different from what I require."

The kiss just now was just an accident. Xu Xiaomei chose to forget it, and He Yuzhu certainly wouldn't mention it again, as if it had never happened.

"Let's go back. It's already late. We can think about it tomorrow. Maybe we can find the answer tomorrow if we can't figure it out now."

"Okay, I'll pack up and then we'll go back."

He Yuzhu didn't bother to think about it. He packed up his things, put some soap on, washed his hands, and came out to see that it was raining. He asked, "When did it start to rain?"

"It happened not long after get off work. You might have been too focused to notice it."

After saying this, Xu Xiaomei opened the yellow bamboo umbrella in her hand and said, "I looked everywhere, but I only found this one."

He Yuzhu was surprised and asked, "No more umbrellas?"

"No, I checked your office too."

He Yuzhu felt a little uncomfortable. If there was only one umbrella, the two of them would have to go home together.

It wouldn't matter if it were any other time, but just now the two of them had a small accident, so it was a bit awkward to hold an umbrella together.

I wanted to go into the office and get an umbrella from the space, but Xu Xiaomei had already found it, so this method could no longer be used.

Xu Xiaomei stamped her feet and said angrily, "I'm not afraid of my brother-in-law, so what are you afraid of?"

He Yuzhu was actually just worried about Xu Xiaomei. Since he said so, of course he would stop worrying about it.

Picking up the yellow bamboo umbrella, Xu Xiaomei opened it and got under it. They locked the door and hurried back, one step at a time.

At the beginning, there was still some distance between the two, but the dirt road was too difficult to walk on, and the two soon staggered and bumped into each other from time to time.

In addition, the rain was falling at an angle, and there was no time to hide from the rain. Sometimes, in order to prevent Xu Xiaomei from falling, He Yuzhu had to support her.

By the time Xu Xiaomei and others realized that they were being held in He Yuzhu's arms, a long time had passed.

I was too embarrassed to struggle anymore and just told myself secretly that this was my brother-in-law and he was just trying to hide from the rain.

The most difficult section of the road is outside the city. It becomes muddy when it rains. Fortunately, we quickly entered the city. The streets were all asphalt roads, and even the alleys were paved with thin stone slabs.

At this time, Xu Xiaomei took the opportunity to break free from He Yuzhu's embrace, but her face was red, like a ripe green apple.

He Yuzhu also became more sober. Xu Xiaomei was still young and had just become an adult, so it would be better not to provoke her again.

In this way, the two of them held the yellow bamboo umbrella together and returned home.

Xu Xiaomei finally breathed a sigh of relief. She was afraid at one point that He Yuzhu would do something to her, so she rushed into the yard without even saying hello.

The next day at work, the two of them resumed their polite relationship as ordinary colleagues, but Xu Xiaomei sometimes would daydream and think about embarrassing things.

He Yuzhu didn't have so much free time. The most important thing right now was to solve the problem of parts precision. After studying for a long time, he really couldn't find a solution, so he went to the heavy machinery factory and found Tong Zhi.

But he didn't believe it at all and asked in surprise: "You said you used those machines to rebuild a lathe?"

"Yes!"

"It's a liar!"

"Why would I lie to you? Why don't you go over and take a look?"

"Okay, wait till I get off work."

Tong Zhi thought, who cares whether it is true or not, at least I can have a meal cooked by He Yuzhu when I go there at noon.

After get off work, Tong Zhi called Dazhuang, and the two of them followed He Yuzhu to the machinery factory.

Looking at the brand new machine tool in front of them, the two were stunned. Dazhuang asked:

"I asked, which factory produced this and why is there no nameplate?"

"I said I made it. Look, there are a few spare parts here."

He Yuzhu pointed at the shelf as he spoke. The two looked up and saw that there were indeed a few commonly used parts on the lathe. They hadn't paid attention to them when they came in just now.

"Did you really do this?" Tong Zhi asked.

"Why don't you believe me?"

"No, you've only been learning about machine tools for a few months? Tell me, can you make a machine tool by yourself?"

"I've been studying for a long time. Besides, I'm a genius. I can understand a lot of things very quickly. Of course I can learn things quickly."

Tong Zhi curled his lips, but was unable to refute He Yuzhu's words.

When I taught him to read blueprints and design production processes, he indeed learned quickly, and I was very jealous of him.

I just didn't expect that in just a few months I would be able to grow to this point and be able to manually make a machine tool.

"Okay, even if you did it, then you came here today to show off naked?"

"Didn't I tell you that this lathe is usable, but the error is a bit large."

"Let me see."

After Tong Zhi finished speaking, he put a workpiece on the lathe and started it. After the production was completed, he measured it and found that it was different from a new lathe. It felt like using an old lathe.

"Oh, this is strange. This phenomenon shouldn't happen."

"Yes, so I asked you to come over and help me figure out what the problem is."

Although He Yuzhu acquired the corresponding knowledge, it was like a person learning from a book, and he did not have much corresponding experience at all.

He only knew how to follow the steps, and when a problem like this arose, there was no answer in the book, so he was at a loss.

"This is the first time I've encountered this problem. The finished product should look like new, but how come you made it look like old?"

Dazhuang asked, "By the way, where are your production drawings? Is there something wrong with the drawings?"

The three of them came to the office. He Yuzhu threw the drawings he had made before to the two of them, then turned and went to the kitchen.

There was no way to ask them to come and help. They still had to take care of the meals, so I had to cook by myself.

After the four dishes and one soup were ready, the three of them ate and chatted. Dazhuang and Tong Zhi were also worried because it seemed that there was nothing wrong with the drawings.

Tong Zhi asked: "Which unit can you get this blueprint from?"

There is no concept of intellectual property rights now, not to mention that the whole country is working as one to build the country.

Therefore, a lot of knowledge is public. For example, it was no problem for He Yuzhu to get the drawings of diesel engines from the heavy machinery factory.

He Yuzhu said: "I drew this myself. I took a lathe apart, measured all the parts one by one, and then remade them according to the dimensions."

Tong Zhi couldn't help laughing after hearing this, and he turned his head quickly with a sip of wine in his mouth.

"Puchi" all of them sprayed on Dazhuang's face.

Da Zhuang reached out and touched it, and shouted in authentic Sichuan dialect:

"I said, if you don't want to drink, don't drink it. Don't waste it!"

Then he got up and went out to wash his face again.

Tong Zhi smiled and asked, "You used this old lathe to carry out the reverse engineering?"

The so-called reverse engineering is to re-survey and map all components using the physical objects at hand in the absence of design drawings.

This kind of production according to the drawings is called reverse engineering.

The West has imposed an embargo on China since the founding of the country, and many products are produced by obtaining blueprints through reverse engineering.

He Yuzhu nodded: "Yeah, is there any problem with that?"

Tong Zhi laughed and said, "You made a mistake in the first step. Others use new machines to do reverse engineering. Do you understand?"

He Yuzhu slapped his forehead and suddenly realized that, yes, he was indeed wrong.

Others do reverse engineering by taking a new machine, measuring each part, and then starting production. In this way, if the parts are qualified and assembled together, it becomes a brand new machine.

But the first step I took was to use an old second-hand lathe for reverse calculation.

When doing reverse calculation, I forgot to take wear into consideration and just mechanically produced the lathe according to the size after wear. So wouldn't the lathe produced have errors?

As the saying goes, you can't see clearly unless the light is on. This is what He Yuzhu understood after the window paper was broken.

If Tong Zhi hadn't pointed it out to me, I would have suspected that the problem was somewhere else and had taken the wrong path.

Maybe I will be able to figure this out after a while, but it will be delayed, or I may never find the reason.

"You have experience."

"Don't say that. Experience can be accumulated, but you have talent."

When Dazhuang came back and learned that this was the reason, he was also surprised and wondered why he hadn't thought of it.

After dinner, the three of them gathered around the drawings again, looking for errors and making modifications.

But it wasn't long before the two of them went back to work, and He Yuzhu had to do it alone.

It was easy to make modifications after knowing the cause, and then we remade the parts. It took a week, and then a brand new lathe was made.

He Yuzhu conducted another test, and this time the results were obviously different from the last time.

Both the precision and stability of the lathe have been greatly improved.

He Yuzhu has not operated the new machine tool yet, but he is sure that the machine tool he made is no worse than a brand new one.

I breathed a sigh of relief. Now I could really say that I had used reverse engineering to build the new machine tool and draw all the production drawings.

After washing his hands, he returned to the office and drank his tea with some pride.

"Director He, there are documents that need your signature."

He Yuzhu looked up and saw Xu Xiaomei walking in.

Put down the teacup and say, "Let me see."

Xu Xiaomei came over, put a pile of documents in the middle of the desk, and did not leave.

He Yuzhu lowered his head and saw that at the top were some purchased rough products, and below were some receipts for reimbursement, leave, etc.

He Yuzhu glanced out of the corner of his eye and saw Xu Xiaomei's hand beside him.

The little hand was white and slender, like the white part of a scallion. He Yuzhu was distracted for a moment and couldn't help but raise his left hand to catch it.

Xu Xiaomei's delicate body trembled, her face suddenly turned red, and she shyly wanted to pull her hand away.

But He Yuzhu was as hard as iron, and Xu Xiaomei didn't move even after using all her strength.

She shyly whispered, "Brother-in-law!"

He Yuzhu said, "Look at this receipt. The calculation is wrong."

Hearing that she had made a mistake at work, Xu Xiaomei quickly looked down at the document and asked, "Where is it?"

"That's it." He Yuzhu pointed it with a pen, and Xu Xiaomei was speechless. This was actually wrong.

He Yuzhu took this one out and put it aside, then continued to look at the documents below.

Xu Xiaomei stood there silently like a child who had done something wrong, and even forgot to slap her own hand.

He Yuzhu played with his slender fingers while reviewing the documents. Unfortunately, the machinery factory was very small and did not have much business, so he finished reading all the documents quickly.

There was no reason to keep Xu Xiaomei any longer, so he had to let go of her hand with regret.

Xu Xiaomei didn't know whether it was because of He Yuzhu's hooliganism or because of a mistake in her work, so she quickly ran out of the office with all the documents.

"Am I that scary?"

He Yuzhu said this, then rubbed his nose with his hand.

Then there was a burst of fragrance. The smell of this vanishing cream was really good.

He Yuzhu packed up and left the office carrying his briefcase.

Seeing He Yuzhu go out, Xu Xiaomei couldn't help but yelled:

"Bah, stinky brother-in-law, you only know how to act like a hooligan."

Then she remembered that her sister was just He Yuzhu's secret lover. Even if she gave birth to a child for him, the child could not have the surname He. She felt disappointed. Did she have to live this kind of life too?

He Yuzhu came to the neighborhood committee and entered the office.

Tian Zao poured some tea, picked it up, took a sip and asked, "What are you doing here today?"

He Yuzhu said with some pride: "Sister, I used the batch of machine tools from the machinery factory and made a lathe."

"Puff" Tian Zao spat out the tea he had just drunk in his mouth. He Yuzhu was a little surprised, but fortunately he was alert and dodged it quickly.

"What did you say?"

He Yuzhu talked about the two lathes he made during this period.

"real or fake?"

"Can I lie to you about this?"

"Are you saying that our machinery factory can also produce lathes ourselves?"

He Yuzhu nodded: "Yes, I came here today just to tell you and to purchase some parts."

"Let's go and report to Sister Hongying."

Tian Zao and He Yuzhu came to a street not far away.

Tian Zao rushed to pour the water, and then He Yuzhu said: "I have recently done some research and found that our machinery factory can already produce lathes independently!"

"Puff!" Li Hongying, who had just taken a sip of water, sprayed out the tea.
