Traveling through 70's wine

Wen Qing still had a batch of pocket radios in her hands, so she decided to go further, to Wuji County to sell them.

On a market day, she took out 100 radios and quickly sold them all at 100 yuan each, earning yuan.

The radios in the department store require a ticket and cost 150 yuan each, so hers is more cost-effective.

Wen Qing pedaled her bicycle quickly, not feeling the cold despite the howling north wind. She rode eastward along the Anding River when she suddenly felt the handlebars tilt and she almost fell off the bike.

She stretched out her legs to support the car, got out and checked carefully, only to find that the tire was flat. She pushed the car along the street and looked around to see if there was a place to repair the car.

After walking for 1 kilometer, I saw a car repair stall. When I got closer, I found that the young man repairing the car looked familiar. After looking more carefully, I found that it was Xiaozhuang who hitchhiked with me.

Just when he was about to avoid her, he suddenly remembered that this was not her real appearance. Xiaozhuang had never seen her before and didn't recognize her.

Wen Qing pushed the cart over and said, "Master, please fix the car."

Xiaozhuang looked up and saw that it was a woman. "What's the problem?" He put down the book in his hand and put on gloves.

"It looks like a flat tire."

Xiaozhuang took the bicycle, squatted down and checked the front and rear tires, "The rear tire is flat."

He turned the car upside down and removed the tire. "Your tire is unusable. You need to get a new one."

"Okay, let's change."

Wen Qing turned her head and looked at the book that Xiaozhuang had placed aside. It was the "Bicycle Maintenance Manual" that she had given him.

"Master, you are new here, right? I didn't see you when I passed by here some time ago."

Xiaozhuang was a little shy, "I just started setting up the stall this week."

"Where did you learn to repair cars, Master?"

“I learned it from reading books.”

Xiaozhuang quickly removed the inner and outer tires and replaced them with new ones. It only took him a quarter of an hour to install them. He pumped up the tires and handed the bike to Wen Qing, "20 yuan."

Wen Qing paid him the money and saw him sitting on the small stool reading a book again. She thought to herself that she would come to see him again in a few days.

A week later, Wen Qing dressed up as a 50-year-old man and rode a bicycle to find Xiaozhuang, who was setting up a stall. She said hello, "Xiaozhuang, do you remember me?"

Xiao Zhuang looked up in surprise, "Brother Li, are you okay?"

"Xiao Zhuang, you've come out to set up a stall. It looks like you've learned the skill."

"Thanks for the book you gave me, Brother Li. It's almost noon. I'll treat you to a meal."

Wen Qing followed him down two alleys and watched him push open a courtyard door. They went in and found a small courtyard with only three main rooms. Xiaozhuang greeted him familiarly, "Old Zhong, we have guests. I'm inviting them to dinner. Please make arrangements for me."

A man in his 30s came out to greet them. "Xiao Zhuang is here. Please sit down first."

After letting the two into the house, it turned out that the three rooms were connected.

Xiao Zhuang: "Brother Li, how did you find me here?"

Wen Qing: "I passed by here today and saw you setting up a stall, so I came over to say hello."

The two talked about their recent experiences.

Xiaozhuang, "After I arrived in Pingjing, I found an opportunity to sell the radio, worked odd jobs for a while, bought some bicycle parts from a scrap yard, and learned how to repair bicycles. I recently started to set up a stall."

Wen Qing was talking nonsense and just said that she was doing business.

Wen Qing: "Where do you live now?"

Xiaozhuang: "I rented a semi-basement with a few other people for 5 yuan a month."

Wen Qing: "It's not bad, there's a place to stay."

Then he said, "I have a radio and a digital watch here, do you want any?"

Xiaozhuang's eyes lit up. He had bought three radios from Wen Qing at the original purchase price of only 3 yuan each, and resold them for 60 yuan. He made a profit of 120 yuan from the three radios, which gave him the opportunity to stay in Pingjing.

Thinking of this, he hurriedly said, "Yes, yes, this is an opportunity to make money given by you, brother, how can I refuse it? How much is a radio?"

"The radio is still 60 yuan a piece, and the electronic watch is 20 yuan a piece."

When Xiaozhuang heard that an electronic watch was only 20 yuan, he thought it was too cheap. Nowadays, watches are 150 yuan each.

"I don't have much capital, so I won't take the radio. The electronic watch costs 50 yuan."

Wen Qing: “Sure.” She took out five boxes of electronic watches from her backpack.

Xiaozhuang opened the box and found that the watches inside looked similar to ordinary watches, except that there was an extra place for button batteries. There were five boxes of watches, three for men and two for women, with ten watches in each box. The women's watches had cartoon patterns on them, and the surface was smaller, making them look more delicate. Each watch was packed in a separate paper box.

Xiaozhuang put away the five boxes of electronic watches, took out a handful of money from his pocket, counted out 1000 yuan and gave it to her, "Brother Li, I will come to you to get the goods after I sell them, but I don't know how to find you?"

"It's okay. I'm nearby. I can see you when you come out to set up your stall. I'll come find you next week."

The two men had their meal and then parted ways. Xiaozhuang did not continue to set up his stall. He went home to put away his car repair tools, packed up his equipment for setting up a stall and went to the South City Farmer's Market, waiting for the night market to open in the evening. Such a cheap watch would definitely be very popular.

Wen Qing developed Xiaozhuang into his downline. After the electronic watches were sold, Wen Qing gave him a bicycle, clothes, tea, and liquor. Xiaozhuang repaired bicycles during the day and set up a stall at the night market at night. His life was busy and he made more and more money. He was considered to have established himself in the capital.

After the Lantern Festival, school starts.

One day after class, Wen Qing was about to go to the library when a male classmate ran over breathlessly, "Student Wen, Professor Wang Huazhen asked you to go to her office immediately."

"Okay." Wen Qing turned and went to the department office building.

I knocked on the half-open door and heard someone inside say, "Come in."

Wen Qing pushed open the door and saw Professor Wang sitting on the sofa talking to an old man in a Zhongshan suit. She hesitated and Professor Wang smiled and said, "Come in and have a seat."

Wen Qing sat next to Professor Wang, who introduced her, "Wen Qing, this is Professor Lin Qiuping. Professor Lin, Professor Lin participated in the design of the first generation of Jiefang cars. Professor Lin, this is Wen Qing, a sophomore in the Department of Mechanical Engineering."

Wen Qing stood up and bowed respectfully to Elder Lin, "Hello, Elder Lin."

Mr. Lin quickly said, "Don't be so polite. Please take a seat, Mr. Wen."

Mr. Lin continued, "I have read the engine modification project plan you submitted and I think it is very good. I would like to hear your ideas."

Wang Huazhen said: "Our starting point is to build a gasoline engine with stable performance, fuel economy and suitable for China's conditions. This plan was put forward by the joint efforts of our mechanical department teachers and students under the leadership of Professor Xu. I wonder if the experts have reviewed it?"

Mr. Lin said: "Experts have been selected from the Academy of Sciences and several automobile manufacturers, and they are currently being reviewed. I personally think this plan is feasible."

Turning to Wen Qing, he said, "I heard that when you participated in the design, you were still a freshman. What is your experience of participating in this project?"

Wen Qing said: "Participating in this project will be of great help to my future studies. Machinery is the mother of industry. The use of machinery has promoted the improvement of productivity and is very helpful in strengthening my country's economic strength."

Mr. Lin asked again: "I have read your proposal. The engine block design is very innovative. The cylinder head you designed is taller than the current cylinder head. What are your thoughts on this?"

Professor Wang Huazhen said to Wen Qing, "Xiao Wen, tell us what you think."

Wen Qing said: "The high cylinder head is to expand the volume of the fuel chamber. By increasing the height of the cylinder and piston, the compression ratio is further increased, so that the fuel is more sufficient and the power of the engine is enhanced."

Elder Lin nodded. "Automobile engines are the weak link in our country's machinery manufacturing. The plan you have completed this time is very good."

After saying goodbye to Professor Wang and Mr. Lin, Wen Qing saw that it was getting late, so she rode her bike back to Erxia Village.
