The train driver in the courtyard

After a while.

Yi Zhonghai, Jia Dongxu, and Jia Zhang appeared next to the pool in the middle courtyard.

Qin Huairu felt embarrassed and did not follow.

The pool in the middle courtyard is the most prosperous area in the courtyard.

No matter what time, there are some old women and young wives squatting there to wash clothes.

The appearance of the three people immediately attracted the attention of many people.

Jia Dongxu held up the banana and said while peeling it: "If you want to eat a banana, you have to peel it. If you don't want to eat it, don't peel it."

Liu Lan was rubbing her big pants, wiped her hands and stood up, her eyes bright: "Jia Dongxu, is this a banana?"

"Ahem, you have pretty good eyesight. This banana is a fruit that only a big leader can afford. In our steel rolling mill, only..."

Before Jia Dongxu finished speaking, he saw two half-year-old children, He Yuyu and Wang Ruxin, walking out of the backyard.

This is not the key, the key is that He Yuyu is holding two bananas in his hand, peeling them both, taking one bite with his left hand and one bite with his right hand.

What's even more annoying is that Wang Ruxin, who is following He Yuyu, is holding a large handful of bananas.

"Ru Xin, you should eat more, this thing will keep you full."

He Yuyu was eating happily when he saw several people standing there staring at him blankly, and he couldn't help but stop.

"What are you doing?"

Jia Dongxu finally reacted at this time.

He closed his mouth, and the phrase "Only Director Yang can eat it" stuck in his throat, choked out from his throat, looked particularly weird.

The residents looked at the three of them holding bananas like treasures, and then at He Yuyu eating bananas like steamed buns.

His face looked as strange as possible, and his eyes when he looked at Jia Dongxu were full of ridicule.

Didn’t you just say that only great leaders can get it?

It is said that the little widow is the smartest, and the former little widow Liu Lan is also considered half-smart.

He slapped his thigh suddenly and said, "Oh, I know, He Yuyu has become the big leader!"

boom.

A burst of laughter broke out by the pool, and the air was filled with joy.

Jia Dongxu's scalp exploded instantly.

He felt that Li Aiguo did it on purpose.

But Li Aiguo doesn't seem to be here.

Jia Dongxu managed to calm down and smiled at He Yuyu: "Yuyu, do you know what you are holding in your hand?"

"Banana, you don't even know bananas, right?" He Yuyu looked at Jia Dongxu like an idiot.

"." Jia Dongxu took a deep breath and continued: "Who gave you this banana?"

"Brother Patriot. Brother Patriot bought a lot of bananas, weighing dozens of kilograms. Sister-in-law Xueru has eaten bananas for the past two days. No, Xiao Wang came to my house to play, and he even asked Xiao Wang to take some bananas back. It’s a pound.”

He Yuyu couldn't understand why Jia Dongxu was so gloomy with just a few kilograms of bananas.

"Xiao Wang, let's go to your house to play." She pulled Wang Ruxin's arm and left the courtyard.

Looking at the backs of the two of them, Jia Dongxu gritted his teeth, Li Aiguo, I'm not done with you.

Chen Xueru ate bananas as food. Qin Huairu only heard this sentence, looked down at her pitiful half banana, and felt an indescribable pain in her heart.

If she hadn't changed her mind back then and persisted for a while, it would be Qin Huairu who was eating bananas now.

Unfortunately, it's too late to regret.

Jia Zhang didn't feel anything at all, and stuffed the banana into her stomach in twos and twos.

He snorted coldly and said: "Damn Li Aiguo, he has so many bananas and he doesn't know how to give some to my family."

Yi Zhonghai has become accustomed to Jia Zhang's strange brain circuits.

He stuffed the banana into his mouth bit by bit, feeling that the banana seemed to have no taste.

Li Aiguo, this guy is getting more and more powerful, you have to be careful in the future.

******
Master Lu once said: "Share happiness with others and your happiness will be doubled; share your sadness with others and your sadness will be halved."

It is a traditional virtue of the Chinese people to bring back good things from other places and share them with relatives and friends.

From a utilitarian perspective, sharing is a social tool and resource sharing, which can make the other party realize your importance.

The cost of bananas in Yangcheng is very low, so Li Aiguo naturally wants to launch banana diplomacy.

But he didn't expect that it would cause a big commotion in the courtyard.

In fact, even if he knew, he didn't care.

Compared with the nonsense in the Siheyuan, Li Aiguo's current work focuses on the development of automatic umbrellas.

The first step in the development plan is to determine whether the patent for the automatic umbrella has been registered.

After all, products are lagging behind. If you work hard to develop an automatic umbrella and the patent is in the hands of others, it will be in vain.

Li Aiguo searched for relevant information through Zong Xianfeng of Beijing University and found that Kobold had created a retractable umbrella in this year (International Patent No.: 100186), but there was no automatic umbrella patent.

After leaving Beijing University, Li Aiguo rode his bicycle to the Qianmen Locomotive Depot Studio.

After half a day of hard work, I drew a complete set of drawings for the automatic umbrella, and also made drawings for the air spring.

The drawings were rolled up and taken to Director Zhang's office in the maintenance workshop.

"Lao Zhang, let's see if we can make this kind of spring."

"Driver Li, why did you remember to study springs?"

Director Zhang didn't think so at first. After taking the drawing, he looked at it carefully and frowned: "Patriot, the structure of this thing is quite simple. We have a lathe and can make it.

However, the requirements for the elastic coefficient and the precise coefficient are too strict. Let alone our workshop, no one in the factory in Beijing can make it. "

"What about Sifang Factory? They should have professional machinery."

As an energy storage device, springs are also the core of unpowered exoskeletons. Li Aiguo cannot give up easily.

"I know Technician Zhou from Sifang Factory and I'll give you a call."

Director Zhang contacted Sifang Factory and explained the technical parameters of the air spring. The other party thought that Director Zhang was being picky.

Why does a small spring need so many standard parameters? Are you manufacturing an aircraft engine?
"Driver Li, are you being picky?" Director Zhang raised his head and looked at Li Aiguo.

Li Aiguo: "."

Seeing that Director Zhang had no hope, Li Aiguo contacted engineer Wang Xianke of the state-owned 5411 Factory.

After receiving the two kilograms of bananas, Mr. Wang studied the drawings seriously.

After a while, he took out a cigarette, took two deep puffs and said, "Aiguo, let me tell you, not even foreign factories can make this thing, let alone our country."

A small air spring can be easily manufactured by any large factory in later generations, but now it is not available in the world!
Even though Li Aiguo knew that the level of metal processing technology and materials was backward these days, he still couldn't help but feel a little frustrated.

Mr. Wang took a big breath and continued: "But I can give you a way. There was an article published in a foreign journal a while ago. There is a three-axis machine in the laboratory of the United States, which is specially used to produce high-strength products. Air spring. If you have any connections, I can ask them to process it for you.”

Li Aiguo knew that it was wise to find Mr. Wang.

A chief engineer at this level can not only receive foreign journals regularly, but also learn about the latest foreign scientific research results through special channels.

Even in this closed era, domestic researchers still find ways to contribute to the country.

Of course, Li Aiguo has a way to contact the old and American side, and that is the Yang family in Hong Kong City.

Back in the studio, Li Aiguo picked up the dedicated phone number and immediately contacted Yang Jizong.

Yang Jizong was a little surprised when he heard that Li Aiguo wanted to build air springs for automatic umbrellas.

"Driver Li, didn't we agree that if you come up with some popular little inventions, we will harvest the world in the name of Hex Technology?

Even if you want to make an automatic umbrella, you can use ordinary springs instead. A spring suitable for automatic umbrellas is produced. "

Li Aiguo leaned on his chair, held the phone, and asked calmly: "Xiao Yang, what is the purpose of making money?"

Yang Jizong scratched his head: "To make money. Of course, to make money is to exchange for foreign exchange, and then go to the international market to buy grain and equipment. In short, just buy, buy, buy!"

"Food and equipment may be snatched away by others. If we want to become truly strong and protect the fruits of our labor, we must develop our own weapons and equipment."

The international stage is actually a straw stage.

If your fist is big, whoever speaks will be heard. If your fist is small, you have to pay tribute to the elder brother.

The big bucks in the Middle East know this very well, and spend huge sums of money every year to buy arms from big brothers around the world.

They are not buying arms, but paying protection fees.

Yang Jizong has been exposed to the Yang family since he was a child. He has a much broader vision than ordinary people, so he naturally understands this.

"That spring is so important." Yang Jizong took a breath.

"It's more important than you think!" After receiving Li Aiguo's confirmed reply, Yang Jizong suddenly became energetic.

He promised on the phone that he would definitely get the three-axis machine needed to produce springs in the shortest possible time.

"Thank you for this. The related expenses can be directly deducted from Hex Technology's dividends."

Just as Li Aiguo was about to put down the phone, he suddenly remembered Mr. Yang's condition and asked casually.

"The old man is very ill this time. He has not seen anyone for more than ten days. Only Butler Bai can enter and leave the temple.

Several of my uncles and uncles have also rushed back from various places. In short, it's okay for now, I will help you get the machine. "

Yang Jizong on the other side of the phone seemed hesitant and secretive about the internal affairs of the Yang family, and Li Aiguo did not continue to ask questions.

The Yang family is a big family. The old man is seriously ill. Even if the sons are united, they will have other thoughts at this time.

Li Aiguo is just an outsider cooperating with the Yang family, and it is not convenient for him to interfere in these matters for the time being.

What he has to do now is to get the automatic umbrella out.

Although it will take some time to make the spring, it can be replaced by ordinary spring for the time being. Continue the following research - making umbrella handles,

Manufacturing an umbrella handle requires an industrial lathe.

Therefore, Li Aiguo occupied the most advanced lathe in the country in the maintenance workshop during a break between driving.

The old master in the maintenance workshop was occupied, so he could only report it to Director Zhang.

Li Aiguo is now the director of the studio. Although he is the only employee in the studio, he is also the director. They are on the same level and he has no control over it.

When Director Zhang saw that it was Li Aiguo, we couldn't control it, so we could only report it to Duan Chang Xing.

Duan Chang Xing was happy when he saw it was Li Aiguo.

"What? Patriot has started doing research again. I support you fully! Lao Zhang, I know that you have a heavy task to prepare the workshop, but I hope you can take the overall situation into consideration. Let's do this. You will immediately send two lathe workers with the highest technical level to assist you. Li Aiguo.”

Director Zhang: "."

He felt lonely after complaining.

With the assistance of professional lathe workers, Li Aiguo made rapid progress. It took him less than a week to create the world's first self-retracting umbrella handle.

With the umbrella handle in hand, the next step is to make the umbrella cover.

Although Li Aiguo can operate a lathe, he cannot make umbrellas.

Fortunately, Comrade Chen Xueru is a tailor. Sewing clothes and sewing umbrellas requires the use of needle and thread. In this regard, she can be regarded as a professional counterpart.

dusk.

The sky was filled with flames and clouds, and the Qianmen Locomotive Depot was still bustling with activity.

At the end of the day's driving mission, Li Aiguo said goodbye to Cao Wenzhi and Liu Qingquan, then hummed a tune and knocked on the door of the section chief's office.

After hearing a response from inside, Li Aiguo opened the door and walked in.

"Comrade Patriot is here. How much did the bananas you gave me yesterday cost? I will give you the money." Duan Chang Xing put down the documents and stood up.

As he spoke, he put his hand into his pocket to get the money.

But he was stopped by Li Aiguo.

"Uncle Xing, you are just like my uncle. My nephew gives me some bananas. If he asks for money again, spread the word. How can I have the dignity to drive a train in the locomotive depot in the future?"

Seeing Li's patriotic sincerity, Duan Chang Xing could only put the money back.

"You kid, don't give me such expensive fruit next time. Your aunt and I are both workers, how can we afford it?"

Duan Chang Xing looked at the young train driver in front of him and felt a little regretful.

He had a niece working in the General Administration, and it would have been nice to have introduced her to Li Aiguo at that time.

"Are you here to talk to me about female students?" Duan Chang Xing poured tea for Li Aiguo and asked with a smile after the two sat down.

Female students, we can talk about this.

Li Aiguo straightened his chest and said: "Chief Duan, you also know that I have to drive every day and take care of the work in the studio. I am very busy and can't spare time to teach the students.

This group of female student teams has special rectification significance in our section, and I can’t let me delay it any longer. "

"That's true." Duan Chang Xing touched his chin and said, "Well, these female students were selected by the General Administration from all over the country. When the leaders of the General Administration come down, I will report your situation to them."

"Thank you, you are really my uncle."

After Li Aiguo finished speaking, he took out a list from his pocket and handed it over: "Uncle, the automatic umbrella project requires material and financial support."

Duan Chang Xing suddenly couldn't laugh or cry.

"I know your kid is not good-hearted."

He picked up the list, glanced at it briefly, and signed his name on it.

"While the supplies department is still at get off work, hurry up and get it. Research the umbrella that can open automatically as soon as possible. Your sister just entered elementary school this year. You can make a small one for her by then."

Seeing his daughter's slavelike appearance, Li Aiguo gave a thumbs up in his heart.

Mr. Xing Duan is nearly fifty years old, and he actually has a five-year-old daughter. He is really ageless, and his heart is neither old nor old.

However, Duan Chang Xing's request gave Li Aiguo new ideas.

As we all know, it is best to cheat children out of their money.

Ordinary products can become two or three times more expensive if they are printed with a few piglets and lambs and are labeled as being for children.

When the time comes, we can design a batch of children's umbrellas separately and bring them to the market, which will definitely sell well.

Li Aiguo was originally just a person who couldn't even set up a street stall, but in this era of limited information, he turned out to be a business wizard.

Dreams begin with your feet.

Li Aiguo took the approval slip and received 120 yuan and a dozen bills from the locomotive depot planning department.

I got on my bicycle and prepared to arrive at the supply and marketing cooperative.

After get off work time, Chen Xueru came back from get off work happily and happily.

Since Li Aiguo came back, she has been living a good life of exercising again.

Exercising is very enjoyable. Chen Xueru is in a good mood these days. Even the students in the literacy class are secretly relieved.

When she walked to the door of her house, Chen Xueru couldn't help but take a breath when she saw that Li Aiguo had bought more than a dozen umbrellas.

"Brother Patriot, why don't we stop being a train driver and sell umbrellas instead?"

"Why are you selling umbrellas?" Li Aiguo pointed to the umbrella, and then took out the automatic umbrella handle.

He pressed the button, and with a snap, the ribs opened.

Chen Xueru's eyes shone when she saw it: "This is too awesome."

"Of course, this is an automatic umbrella. As long as you press the button, the umbrella will open automatically." Li Aiguo said.

Chen Xueru looked at the umbrella handle and suddenly asked: "The price of automatic umbrellas must be much more expensive than ordinary umbrellas. Would anyone really buy an automatic umbrella to save so much effort?"

"Of course, haven't you noticed that people's research is all to facilitate production and life?" Li Aiguo explained: "Making a train is much more complicated than domesticating horses, and making a bicycle is much more difficult than running with two legs. Also, we Do you regret spending so much money on a sewing machine?”

"That's not true." Chen Xueru instantly understood Li Aiguo's thinking.

She put the umbrella on the table, picked up the scissors to remove the umbrella cover, and then tried to install it on the handle of the automatic umbrella.

It's just that because the design of automatic umbrellas is different from ordinary umbrellas, the umbrella surface needs to be modified.

There are two types of umbrellas in this era, one is a bamboo pole and oilcloth umbrella, and the second is a paper flower umbrella.

Paper flower umbrellas are generally used by little girls and are not practical, so Li Aiguo chose oilcloth umbrellas.

This also brings about a problem. The oilcloth is very strong and can be easily damaged during processing.

The umbrella cover was very large, so even if Chen Xueru called He Yuyu over and the two of them renovated the umbrella cover together, several of them were damaged.

Aunt Liu took Li Aiguo's arm and said, "Aiguo, why did you destroy such a good umbrella?"

"Mom, I'm doing an experiment."

Although Aunt Liu didn't know what an experiment was, she felt relieved knowing that Li Aiguo was actually doing serious things.

She knew that Li Aiguo was becoming more and more capable, but she was afraid that Li Aiguo would go astray.

"You guys are busy, I'm going home to cook."

Chen Xueru washed her hands and stood up and said, "Mom, stop working. Two kilograms of mutton were sent to the locomotive depot today. It will be stewed in a minute. The mutton soup replenishes qi and blood. You and Yuudou stay here."

"How embarrassing."

"What's the point of being embarrassed? I heard from Aiguo that you took care of her a lot in the past few years."

Seeing Chen Xueru's sincere affection and He Yuyu's greedy look, Aunt Liu also gave up the idea of ​​going home to cook and squatted down to help clean up the umbrella noodles.
