Inside the team lounge.

Li Weidong leaned on the table and drew the design.

Outside the door, Li Zheng and Niu Meng stood with big eyes and stared at each other, both of them unconvinced.

Since Li Zheng reported Li Weidong's transformation plan to the FAW factory, after careful discussion, the design department boss believes that the chassis scheme has reference value, and the water tank transformation plan has practical value, and the name Li Weidong has been listed in the FAW factory.

Therefore, when Niu Yong reported Li Weidong's idea of preparing to design the central support structure of the long rotating shaft to the FAW Factory, he immediately received great attention from the design department.

The prototype of the liberation truck was none other than the Gil 150.

In addition to the full inheritance of the advantages of the Gil 150, the liberation truck also inherited some design flaws.

One of the most troublesome defects for the FAW plant is that the long rotating shaft is prone to failure.

The FAW plant has already received an improvement plan from the "Likhachev" automobile plant.

However, part of the central support structure, which was developed jointly by the Likhachev and Volvo car plants, had to be imported from abroad, and the foreign exchange in the country was very limited.

Therefore, the design department of the FAW plant is trying to design a central support structure that can be completely localized, but unfortunately due to problems in thinking, there has been no progress.

After learning the news, he was naturally overjoyed.

Immediately sent Li Zheng, a ninth-level engineer, hoping to get new ideas from Li Weidong.

Li Zheng came to the convoy with great interest, and just wanted to rush into the lounge, but was stopped by Niu Meng.

In Niu Meng's words, the master ordered just now that no one else was allowed to go in and disturb his work.

Of course, she was mainly afraid that Li Zheng would pry Li Weidong away.

The master is really in charge of cooking and really teaching to drive.

Of course Li Zheng was not convinced, he was an engineer who could get a salary of more than 100 yuan a month, and he could be stopped by a small female worker.

After a disagreement, the two had an argument and pushed twice, and the result was predictable, and the engineer was defeated.

It happened that Niu Yong went to the factory for a meeting, and Li Zheng couldn't find a way to complain, so he could only stand at the door and shout at the top of his voice.

Li Weidong happened to draw to the key part, and his train of thought was interrupted by the noise.

opened the door and saw that one of them outside was his own apprentice, and the other was a prostitute for nothing, so he was immediately furious and cleaned up both of them.

Both blame each other for their guilt.

...

After drawing the drawings of the ball bearings, Li Weidong breathed a sigh of relief.

According to the domestic technical level, this kind of ball bearing can be manufactured.

The next step is to calculate the specific data and mark it on the drawing.

The work was more than half done, and then the two were called in.

Li Zheng didn't care about fighting with Niu Meng, so he ran to the table when he entered the house, picked up the drawings and studied them carefully.

He is an expert in car design himself, so he naturally knows how to do it, but he can't help but swallow his saliva just by looking at it twice.

"This, ball bearings can still be designed like this?"

"Only by designing the ball bearing into four parts: ball, inner ring, outer ring and retainer, can the force be decomposed to the greatest extent, and the high chromium steel with a Rockwell hardness of more than 61 can be applied, and at the same time..."

Although Li Weidong was not satisfied with Li Zheng's white prostitution behavior, he still explained the design idea in detail.

After all, the central support mechanism will be manufactured as soon as possible, and the drivers will be less dangerous when they run the car outside.

Now the domestic industry is almost starting from scratch, if everyone pays attention to returns, then when will China rise?

Li Zheng nodded frequently and admired again and again.

And Niu Meng's little face is also happy, or the master is amazing, this engineer is a big radish.

Drawing drawings was a very difficult job, especially since Li Weidong had to take into account the level of material manufacturing in Huaxia at this time.

So, one morning also drew the ball bearings.

Seeing that the time was almost noon, Li Weidong was about to go back to the courtyard.

Today, Yu Li said that he was going to clean the house, and as a man in charge, he always wanted to condole.

He patted Li Zheng, who was still studying the drawings, on the shoulder, and said, "I sometimes need to go back, so I will trouble you to take my apprentice to eat at noon, and you don't need to go to the restaurant outside, just deal with it in the canteen." ”

Li Zheng looked up at Niu Meng, a skinny girl, how much can she eat?

"Don't worry, your apprentice is my apprentice, and I must have her well fed."

Ahem, you can take advantage of your words!

Li Weidong smiled, carried Li Zheng on his back, and gestured at Niu Meng in a palm-splitting posture.

Niu Meng nodded knowingly.

Master, please rest assured!

...

The other side.

Although he said that he would come to help Li Weidong clean the house at noon, Yu Li came early in the morning.

Anyway, I'm idle at home, so I can do more work if I come early.

Wait for Li Weidong to come back and give him a big surprise.

Thinking like this, Yu Li's motivation suddenly rose, first she cleaned the house, and then wiped all the furniture with a rag.

Yu Li didn't have a job at home, and she did all the housework on weekdays.

And because he didn't have a salary, he also developed a good habit of thrift and thrift, and he didn't even want to use hot water.

Soon Yu Li's bangs were sticky to her forehead, and her little hands were red from the cold.

The three mothers went to the backyard to cut leeks, and when they saw this scene, they suddenly felt a heart-wrenching pain in their hearts.

In her mind, Yu Li is the perfect daughter-in-law.

Seeing that Li Weidong was not at home, she boldly walked into the house, smiled awkwardly, and said, "Yu Li, why are you doing this?" Li Weidong has no support from the elderly, and his family is poor, why do you recognize him? He's using you like an old mother! ”

Yu Li stopped her hand, shook her head and said, "Three mothers, Brother Wei Dong is not what you think, he is good to me, I am willing to help him clean up the housework." ”

The three mothers secretly hated it, and Li Weidong, this kid, didn't know what kind of drug Yu Li had taken him.

After the three mothers left, Li Weidong's wife and daughter-in-law passed by from time to time at the door of his house.

It was the first time they had seen such a diligent girl, who had not been idle all morning, and even the glass windows were polished brightly.

In the winter, who cleans the glass.

At noon, Aunt Yi finally couldn't bear it anymore and walked in.

Yu Li was eating, and when she saw the black nest and boiled water on the table, Aunt Yi couldn't help it anymore.

"Yu Li, if Li Weidong's kid threatens you, you can tell Aunt Yi. Now it's a new society, and it's not allowed to engage in child brides. Don't worry, Uncle Yi and I will help you make the decision. ”

Yu Li suddenly couldn't cry or laugh, she worked sincerely, how could these people always want to be crooked.

"Brother Wei Dong is very good to me, I have a small amount of food, and I still have to work later, so I didn't get angry."

"Still working? You've been working all morning! ”

An aunt sighed in her heart, Li Weidong, this kid really doesn't use his daughter-in-law as a person.

When the first aunt came out of the house, she told the old women and daughters-in-law under the old camphor tree what she saw.

The old women and daughters-in-law gasped together, they had only heard of the mother-in-law abusing their daughters-in-law, but they had never seen their husbands so ruthless.

"Li Weidong's kid has a good eye and has found a child daughter-in-law."

"Alas, how smart Yu Li's girl used to be, how did she become stupid with Li Weidong."

"That's it, I really didn't see it, she is also a girl from the alley of the old capital, and the old Yu family also has the face to face others. How can she be as hard-working as a girl in the countryside. ”

"Rural girl? Qin Huairu is from the countryside, and I didn't see her so diligent. ”

"With such a daughter-in-law, Li Weidong has enjoyed happiness in his life, and the old Yan family has lost a lot."

...

They didn't notice that the three mothers and Jia Zhang were standing next to them with bowls.

Hearing the discussion, the two of them suddenly turned blue with anger, glanced at each other, and turned their heads and ran home.

I can't talk about it this day!
