The train driver in the courtyard

The toy market is a huge market in later generations, with annual profits reaching hundreds of billions.

Although the domestic consumption level is not high these days, adults are always willing to grit their teeth and spend money for the sake of their children.

The most important thing is that the toy manufacturing method is simple and there is no need to use points to purchase technology.

Li Aiguo has always had the idea of ​​bringing those classic toys of later generations to this era.

Not for money, just for fun.
cough cough.

Of course, if I could become the toy king by the way, Li Aiguo would not refuse.

Just never had the chance.

After all, a rough man who sits at home making toys for children will definitely be criticized for not doing his job properly.

Now the opportunity has finally come.

On the kang.

As the spring turned, the little frog jumped, jumped, and jumped.

Little Hongsheng stared at the little frog with his bright eyes, laughing loudly.
Li Aiguo held Xiao Hongsheng in his arms and rubbed his head lovingly: "Little boy, how about the toy Daddy made for you? Is it fun?"

Xiao Hongsheng: “Hehehe”

It doesn’t matter whether you make money or not, the most important thing is that your children are happy.

You see, even Chen Xueru became interested in the iron-shell frog and was squatting there having a lot of fun playing with it.

What is emotional value?

That's it.

He Yushui heard the noise and ran over. When she saw the iron-shell frog, the little girl couldn't take her eyes off it.

When He Yushui learned that this thing was made by Li Aiguo, his face was full of anticipation.

"Brother, can you help me build one too?"

"The cost of making an iron-shell frog is not low. It requires metal materials, clockwork devices, screws, and nuts." Li Aiguo grinned.

He Yushui looked at the cute iron-shell frog, gritted his teeth and said, "I will help you clean your house for half a year, including washing the sheets!"

"make a deal!"

Well, this thing was just made and one was sold.

This sales speed really exceeded Li Aiguo's expectations.

Li Aiguo felt that the work of producing iron-shell frogs should be put on the agenda as soon as possible.

As for diapers, since it involves finding suitable materials, there is no point in being anxious, so we can only put it aside for now.

There are also baby strollers.

With a stroller, you don't have to hold your baby all the time.

As night falls, the entire courtyard is immersed in silence.

With the iron-shell frog attracting Xiao Hongsheng, Li Aiguo was finally able to have some peace and quiet for a while.

He put the materials for making diapers into the drawer and took out some new manuscript paper.

The pen tip slid across the paper, leaving behind a line of neat handwriting: "Iron Frog Manufacturing Project."

The night, like a piece of black silk, slowly spreads over the courtyard, quiet and deep.

Inside the house, dim lights sprinkled in every corner, outlining a warm outline.

Chen Xueru hummed a melodious lullaby, and gradually, the little one fell asleep peacefully in this sweet melody.

Chen Xueru tucked in the quilt carefully and stared at the child quietly for a moment, as if she could not get enough of looking at that childish little face.

Then he gently stood up, put on some clothes, and slowly walked out of the inner room.

"Brother Aiguo, it's already late, go to bed early."

"It'll be ready soon."

The manufacturing technology of the iron-shell frog is very simple.

Li Aiguo, now a master of mechanical design, only used 50% of his skills and drew the blueprint in just two hours.

Tomorrow is a day off. After perfecting the production steps, we will find a way to produce it in large quantities.

Li Aiguo carefully put the manuscript into a canvas bag, stood up and walked to Chen Xueru, gently put his arm around her slender waist, and walked into the inner room together.

As soon as he stepped into the house, Li Aiguo was stunned by the scene before him.

I don't know when, Xiao Hongsheng "opened up" a winding "long river" on the kang.
At this moment, he was lying on the bed, staring at Li Aiguo with his big round eyes without blinking.

Perhaps the little guy also vaguely realized that he seemed to have done something "bad", and suddenly his little mouth curled up and he burst into tears, and the crying instantly broke the silence in the room.

Upon seeing this, Chen Xueru hurried over, gently held Xiao Hongsheng in her arms, and coaxed her in a soft voice.

Under the dim incandescent light.

The unique smell of boy's urine, the faint milk fragrance in the air, the loud crying of the child and the gentle coaxing of the mother intertwined and floated into Li Aiguo's ears.

Li Aiguo felt as if he had officially started his life as a stay-at-home dad.

After coaxing the child and changing the sheets, it was already midnight.

Li Aiguo and Chen Xueru were both exhausted and fell into a deep sleep on the bed.

the next day.

After Li Aiguo ate two large white flour buns, a large bowl of cornmeal porridge and five eggs, he rubbed his stomach and burped deliciously.

He Yushui came to Li's house early in the morning with her hands behind her back. Her bright big eyes looked around the house.

Chen Xueru knew what the little girl was thinking, so she took out the iron-shell frog and handed it to her.

"Yushui, Hongsheng has been making a fuss for half the night, but now he is still sleeping. You can take it and play with it first."

"No, our teacher taught us to be self-reliant." He Yushui looked at the iron-shell frog with envy, bit her lip, and waved her hand firmly.

This girl has a pretty positive outlook. Li Aiguo pointed inside the house and said, "First clean the house and wash the sheets. You'll be allowed to play for half a day."

"Brother, it's a deal!" He Yushui took the iron-shell frog.

To Li Aiguo's surprise, she did not start cleaning the house, but turned around and ran out of the house.

He Yushui came to the third uncle's house, when the third uncle had just finished his meal.

"You're here to look for Jie Di, right?" When the third aunt saw He Yushui coming in, she shouted into the house, "Yan Jie Di, Yushui is here."

Although Yu Shui is several years older than Jie Di, they often play together and have a good relationship.

Yan Jiedi was doing her homework and had been feeling bored for a long time. When she heard the shouting, she put down her pen and ran out.

"Yushui, are you still going to pick up coal cores today?"

"No, I've brought you a fun thing." He Yushui placed the iron-shell frog on the table.

Yan Jiedi looked at the strange-looking frog with a bewildered look on her face: "Rainwater, what is this..."

He Yushui did not answer, but gently twisted the spring, and the iron frog jumped and jumped.
"It, it can jump by itself!" Yan Jiedi's eyes were instantly attracted by the iron-shell frog.

She rubbed her hands unconsciously, and asked with a hint of anticipation and trepidation:

"Sister Yushui, can you let me play for a while?"

What He Yushui was waiting for was this sentence:

"Of course you can, but the iron frog is not mine, I rented it. We are friends, so I'll give you a discount. As long as you help Aiguo clean up the house, I'll let you play with it for five minutes."

"Cleaning the house? That's a piece of cake! I'll go now."

Although Yan Jie Di was young, she was an expert at housework in the courtyard. She could wash clothes at the age of four, cook at the age of five, and pedal the electric wheel at the age of six.

Especially since she has been pedaling the electric wheel all year round, her strength is much greater than that of ordinary children, and she doesn't take cleaning the house seriously at all.

At this time, Li Aiguo was studying the production steps at the door. When he saw Yan Jiedi coming over, he greeted her with a smile.

Yan Jiedi responded and went straight into the house to start working.

"Hey, this girl"

Just kidding, the third uncle is behind Yan Jiedi.

The third uncle often rented Yan Jie Di to other residents to look after their children and clean the house, charging a high fee.

Does Yan Jiedi’s current behavior count as forced buying and selling?

"Jie Di, what are you doing?"

Li Aiguo felt strange and was about to go up to stop Yan Jiedi.

He Yushui came over and took Li Aiguo's arm: "Brother Aiguo, Jie Di cleans the house for me. Now I can legitimately use the iron-shell frog for half a day."

Li Aiguo: "."

Looking at those big eyes full of cunning, he felt that He Yushui was not a simple girl.

However, He Yushui did not violate the agreement.

"Okay, you can play for half a day today."

Li Aiguo thought that the matter was over.

He was totally wrong.

After Yan Jie Di cleaned the house and washed the sheets, He Yushui handed the iron-shell frog to Yan Jie Di as agreed.

But the location she chose was very clever, right next to the pool.

Today is the weekend, and all the children in the compound are playing here. Some are pushing iron hoops, some are catching Galaha, and some are riding horses. It is very lively.

At this time, an iron-shell frog jumping on the ground instantly attracted the attention of all the children.

"Yeah, this thing can move by itself."

Liu Guangtian, Yan Jiefang, Banggeng, Zhang Gangzhu, Damao, Ermao and seven or eight kids from next door all gathered around.

Banggeng reached out to catch the iron-shell frog.

"Snapped!"

A stick came over and hit the back of his hand.

He Yushui said with a fierce face: "This is a valuable toy. You know, you can't even buy it in Beijing Department Store. What if it breaks?"

If it was someone else who did it, Bang Geng might have already asked for reinforcements by now, but He Yushui was a daring person, and his beatings were particularly painful.

Bang Geng could only squat on the ground.

Liu Guangtian asked: "Sister Yushui, this frog is so interesting, can I play with it for a while?"

"Of course you can, but you can't play for free, right? We are neighbors, I'll give you a discount, just help me pick up two boxes of coal cores." He Yushui looked like he had suffered a great loss.

"Deal!" Liu Guangtian agreed immediately.

Picking up coal cores is just a waste of daytime time, but you can't miss such a fun iron-shell frog.

Besides, Liu Guangtian is the main force of the Liu family in picking up coal cores.

Who are you picking up coal for? Isn’t it?

"What about me? What about me? I want to play too." Yan Jiefang raised his hand actively.

"Jiefang, you can fish, right?" He Yushui's eyes turned.

Yan Jiefang patted his chest and said, "I learned it from my father!"

"Exchange it for five fish." He Yushui said.

"make a deal."

The biggest characteristic of children is that they like other people’s toys.

Especially toys like the iron-shell frog are super fun.

Seeing that Yan Jiefang and Liu Guangtian could play with the iron-shell frog, the remaining children also wanted to play with the iron-shell frog. He Yushui assigned them tasks respectively.

Zhang Gangzhu is very strong. At such a young age, he can carry 50 kilograms of things. He is responsible for helping Aunt Liu move the coal briquettes out of the cellar.

Da Mao and Er Mao followed Liang Ladi to the suburbs to pick wild vegetables all day long. They were experts in picking wild vegetables and promised to each contribute two baskets of wild vegetables.

As the second owners of the film and television company, Hailong and Haitao promised He Yushui that they would reserve a good seat for him when Xu Damao showed the movie.

He Yushui now turned into a profiteer, making a fortune by relying on the temporary use rights of the iron-shell frog.

The little girl tilted her head and smiled. This is much more fun than the iron-shell frog.

Seeing that his friends could all play with the iron-shell frog, Banggeng raised his hand unwillingly: "Aunt Rainwater, what about me? What about me?"

He Yushui stared at the stick for a long time but couldn't come up with any idea.

"Bang Geng, what can you do?" Bang Geng raised his head proudly: "Grandma said I can do great things!"

"." He Yushui was silent for a moment, then said, "Then go home and play in the mud."

Other children can play with tin-shell frogs, but Banggeng can only play with mud.

So wronged!

Banggeng didn't dare to argue with He Yushui and could only go home crying.

Jia Zhang was sewing shoe soles when she saw Bang Geng crying and felt heartbroken.

She also had time to sew the soles of her shoes, and quickly hugged the stick stem in her arms: "Grandson, if anyone bullies you, tell grandma and I will go and settle the score with him."

"What rain is it?"

When she heard He Yushui's name, Jia Zhang looked a little embarrassed.

In this compound, there are not many people who can make Jia Zhang afraid. One is Li Aiguo and the other is He Yushui.

He Yushui dared to confront Jia Zhangshi.

Read more latest popular novels at 6.9*shuba!

Especially because in the incident of Shazhu entering the fence, what Jia Zhang and Qin Huairu did was not glorious.

"My eldest grandson, it's just a tin toy. Wait for your father to come back and ask him to make one for you. Your father is a great fitter, much better than a train driver."

"real?"

"Of course!"

Jia Dongxu returned home humming a little tune, and Jia Zhang gave him the task of making an iron-shell frog.

Jia Dongxu originally wanted to lie in bed and rest for a while, but now he had to get up.

After he figured out what the iron-shell frog was, he went to the steel mill in the afternoon to find some scraps, spent some money on a cigarette, and borrowed a machine tool.

In the evening, Jia Dongxu returned home, took out the iron-shell frog from his canvas bag, and handed it to Banggeng.

"Look, son."

"Oh, it's the Iron Shell Frog." Banggeng hugged the Iron Shell Frog and ran to his little friend Ben.

He held up the iron-shell frog and showed off: "Liu Guangtian, did you see that? I also have an iron-shell frog. Only I can play with it. You are not allowed to play with it."

Liu Guangtian was playing with a real iron-shell frog and was stunned when he heard this.

"Bang terrier, where did it come from?"

"Of course my dad helped me do it. My dad is so awesome." Banggeng felt the envious gazes of his friends and raised his head proudly.

"Really? Can you, a frog, jump?" He Yushui felt something was wrong.

"Of course. Frogs can jump."

Banggeng put the frog on the ground and reached out to wind the spring.

What, no clockwork?
That doesn't matter.

Bangteng poked the frog with his finger: "Jump."

frog:"."

The stick knocked on the frog's head and said, "Jump!"

frog:"."

Liu Guangtian laughed loudly: "Bang Geng, your frog is a dead frog, how dare you take it out."

The essence of the iron-shell frog lies in its ability to jump.

When the guys saw Banggeng using a dead frog to trick people, they immediately burst into laughter.

Bang Geng's face turned visibly red.

He stood up suddenly, picked up a brick and smashed it down.

"I'm telling you not to jump, I'm telling you not to jump, I'm telling you not to jump."

The iron-shelled frog was smashed into iron sheets.

"The market research has been completed. Judging from the appeal of the Iron Frog, if it is launched at the end of the year, it can swindle all the New Year's money of the children in Beijing!"

The tip of the pen wrote a line of words on the notebook, and Li Aiguo put the notebook away and put it into his canvas bag.

At this time, Xiao Hongsheng's loud crying and Chen Xueru's tired voice came from the room: "Brother Aiguo, the child wet the bed again."

Li Aiguo: "."

The next day is still a rest day.

However, Li Aiguo rode his bicycle to Qianmen Locomotive Depot early in the morning.

After knocking on Chief Xing Duan’s door.

Snapped!
The drawings were slapped on the table.

Snapped!
The production process instructions were placed on the table.

"Transfer the money!" Li Aiguo sat down opposite Director Xing.

"Aiguo, what did you come up with this time? Did you improve the steam engine or the railroad?" Director Xing looked at the blueprint and frowned: "Children's toys?"

Section Chief Xing put down the blueprint and scratched his head: "Aiguo, we are the locomotive section, shouldn't we design something related to trains?"

"Captain Duan, do you still remember the umbrella?" Li Aiguo said slowly and calmly.

As soon as these words were spoken, Director Xing's face changed.

When the automatic umbrellas were first put into production, the leaders of the section, including Section Chief Xing, did not pay much attention to it.

After all, how much money can you make from an umbrella?
Therefore, Director Xing Duanchang simply commissioned the Fangshan County Hongqi Umbrella Factory to help produce umbrellas.

But who would have thought that sales of automatic umbrellas would become so popular.

Last year alone, Qianmen Locomotive Depot earned hundreds of thousands of yuan in profits.

Subsequently, automatic umbrellas were included in Hextech Technology's procurement sequence and were also very popular in Hong Kong, Europe and the United States.

To this end, the Qianmen Locomotive Depot built a third-line factory in Panggezhuang - the Red Star Umbrella Factory, which specializes in the production of automatic umbrellas.

Although the sales profits of Red Star Umbrellas in Hong Kong, China, Europe and the United States belong to the ministries and Hextech.

However, as the "OEM" party, Qianmen Locomotive Depot can also make huge profits.

It is precisely because of these profits that the Qianmen Locomotive Depot can introduce new equipment and new locomotives and provide benefits to the employees of the locomotive depot.

Now the welfare of ordinary employees in Qianmen Locomotive Depot is the best in the entire railway bureau.

"Aiguo, do you mean that this iron-shell frog has better financial prospects than an automatic umbrella?" Director Xing was somewhat tempted.

He handed Li Aiguo a cigarette and lit one for himself.

As a section leader, Section Chief Xing has two working principles.

One is to complete the tasks assigned by superiors and promote railway transportation work.

The second is to let the employees in the section live a good life.

As long as these two principles are met, everything can be discussed.

“I can’t even bear to leave Greater China.”

Li Aiguo put the bag of Daqianmen into his pocket with a look of disdain and said slowly: "Just the iron-shell frog is definitely not enough, but if there are other toys and baby carriages, then the money earned from this project will be dozens or hundreds of times that of the automatic umbrella project!"

"These are just children's toys. They are not to be eaten or drunk. Who would be willing to spend money on them?" Director Xing was skeptical.

Li Aiguo asked: "Duanzhang, if you only have half a pound of White Rabbit candy at the end of the year, will you eat it yourself or save it for your children?"

Xing Duanchang blurted out: "Of course it's for the children."

As soon as the words came out, Director Xing realized Li Aiguo's purpose.

He looked at Li Aiguo with the eyes of a profiteer: "Good boy, you are calculating these parents."

"How can this be a calculation? These toys are not just ordinary toys.

Take the iron-shell frog for example. It contains rich physical knowledge and can also exercise children's hand-eye coordination ability.

According to the law of use it or lose it, children can improve their IQ by playing with toys frequently.

With a higher IQ, we can contribute better to the construction of the motherland in the future.

As for the baby carriage, it is even more amazing.

It can help adults save energy. With extra energy, they can focus more on production work.

Director Duan, we are not making money, we are contributing to the construction of the motherland!"

Can making toys contribute to the motherland? Xing Duanchang instinctively thought that Li Aiguo was talking nonsense.

But Li Aiguo's reasons were so sufficient that he was unable to refute them for a while.

"How about this, let's test the waters first. Since the iron-shell frog has been designed, we can ask the Red Flag Umbrella Factory to help produce it."

At this time, Director Xing Duan was also somewhat tempted and decided to go crazy with Li Aiguo.

"As for the baby carriage, you can get the materials you need directly from the logistics department. If you are missing anything, just ask the logistics department to help you mobilize it."

Li Aiguo was surprised that Duanchang Xing could cooperate so well.

After all, for a leader who has been playing with trains all his life, if you ask him to spend a lot of money to make toys for you, it would be a favor for him not to kick you out.

Of course.

Director Xing Duan also has his own plans.

Even if the sales of the iron-shell frogs are not ideal, the section can still distribute the iron-shell frogs as welfare to the employees of the Qianmen Locomotive Depot or even the Beijing Railway Bureau.

The Beijing Railway Bureau has tens of thousands of employees and hundreds of thousands of children, which is itself a huge consumer group.

This is what is called "development is easier with railways behind it".

Li Aiguo once again confirmed that his decision to join the locomotive depot was the right one.

In particular, the locomotive depot has always been prone to Rayleigh winds.

Li Aiguo came to the Panggezhuang Red Star Umbrella Factory with the drawings and the relevant documents.

Director Chen of the umbrella factory was originally the deputy section chief of the logistics department and had dealt with Li Aiguo many times.

Seeing that Li Aiguo wanted to make toys this time, Director Chen was a little surprised, but he still made the promise without hesitation.

"Driver Li, don't worry. The structure of this iron frog is not complicated. Our umbrella factory is fully capable of producing it with guaranteed quality and quantity."

"Old Chen, children are the future successors. The Iron Frog is for children to play with, so the quality must be guaranteed."

Although Li Aiguo believed in the strength of the Hongqi Umbrella Factory, he still gave the usual reminder.

"We have a complete quality inspection team to absolutely guarantee the quality."

The umbrellas produced by the Hongqi Umbrella Factory can now pass the ministry’s acceptance and are sold well overseas, which demonstrates their capabilities.

Li Aiguo was not too worried. After chatting for a while, he returned to the workshop of Qianmen Locomotive Depot.

The Iron Shell Frog is about to be produced now. Once the sales of the Iron Shell Frog are satisfactory, the production of the baby carriage should also be put on the agenda.

Li Aiguo had to prepare the drawings of the baby carriage in advance.

In fact, baby strollers have already appeared in China during this period.

Nan Yi's family's baby carriage is made of bamboo strips.

It has the shape of a small basket with four wheels underneath, and a small door that can be opened and closed is made on one side to facilitate children to enter and exit.

The baby carriage in the third uncle's house is a basket.

The baby stroller for my sister-in-law's house was bought by Chen Fangxuan from a trust store.

It is made of elm wood and has a rectangular shape. It is small and exquisite. The main components include a tray for placing toys, a curved seat, foot pedals, etc. There is not a single nail used in the whole vehicle, and all the components are interlocked with mortise and tenon joints.

The baby stroller that Li Aiguo wanted to design was similar to the best-selling baby stroller on JD.com in later generations.

The main frame is made of aluminum, with shock absorbers on the wheels, a small mattress inside, and a sunshade on top.

Of course, this kind of stroller itself is a high-end product, it is very expensive and the price is not cheap.

The structure of a baby carriage is much more complicated than that of a tin-shell frog.

Li Aiguo also had to find a way to figure out where to get the materials for making diapers.

We still have to drive during the day.

Therefore, the development of baby strollers has not progressed quickly.

But Li Aiguo is not in a hurry.

After all, babies can only ride in a stroller when they are about 8 months old. Riding in a stroller too early will affect the normal development of the spine, leading to spinal deformities, physical deformities, etc. (End of this chapter)
