Facing two immortal classmates with the ability to make money, Yu Hua had no choice but to nod his head: "When will you be free?"
"I'm available every day. I'm free during lunch break and evening." Zhou Yuan responded.
Fang Yu said: "Me too."
There is about an hour and a half lunch break at noon, and there is also an hour and a half break in the evening. Many students usually use these times for self-study, and Zhou Yuan and Fang Yu are no exception.
However, for the important cartography class, Zhou Yuan and Fang Yu did not hesitate to abandon their original self-study arrangements and plans.
mapping!
This is a key technology that countless students strive for but cannot get started with. It is one of the important knowledge that Western countries and Japan strictly guard against China.
Their own study plans and arrangements were nothing compared to the drawings that symbolized the future.
Zhou Yuan and Fang Yu did not ask how Yu Hua learned to draw. They only knew that they had to study hard.
As for the source of Yu Hua’s drawing ability?
It's not important.
Everyone has their own secret.
"In this case, let's set it in the fourth empty classroom on the third floor every evening. There are usually no students there. There will be one class every day, about twelve periods. Is there any problem?" Yu Hua asked seriously after receiving the answers from the two people.
.
Fang Yu couldn't wait to hear the time and place given by Yu Hua. Before Zhou Yuan could speak, she immediately said, "No problem, but are you going to go to class today?"
"It will be tomorrow. Drawing is a very important course. I want to sort it out." Yu Hua shook his head. He was not going to rush into class today. He wanted to sort out the course.
As the common technical language in the field of engineering, drawing essentially reflects the engineering standardization of the entire country. However, a very embarrassing thing happened. Is there any real engineering standardization in the Republic of China today?
No.
The current Republic of China has not even completed the most basic heavy industry. The entire country cannot even produce a single high-quality screw that meets the standards, let alone formulate the most important standards in the field of engineering.
Drawing is divided into three categories: engineering drawing, chemical drawing and mechanical drawing.
The drawings mastered by Yu Hua were the unified drawing standards stipulated by China in the prosperous times of later generations. They contained a lot of knowledge related to computer drawings and were very different from the actual situation in the engineering field of the Republic of China today.
There will be computer-aided drafting in later generations, but is it available today?
No.
It is inconsistent with the actual situation to use the standards of the later dynasty to require the industry of the previous dynasty.
Adapting measures to local conditions is the most important thing.
After unexpectedly learning about the knowledge blockade from Zhou Yuan, Yu Hua was inspired by it and prepared to learn from later national unified cartographic standards to build a cartographic standard for the current era.
Constructing the cartographic standards of 1937.
Drawing standards are undoubtedly extremely important. With tall buildings rising from the ground, having drawing standards means holding the key to the future, which is the key to standardized industrial manufacturing and production.
In the fields of engineering, machinery, chemical industry, etc., all manufacturing and construction are based on drawings. Without drawings, nothing can be done. This is the core reason why Western countries and Japan include drawing in the scope of knowledge blockade.
Of course, as for teaching Zhou Yuan and Fang Yu, who are essentially unrelated to each other, the knowledge of cartography, Yu Hua is not worried about whether there will be antagonism or betrayal in the future.
As long as these two classmates are not traitors, even if they become enemies in the future, so what?
To them, the cartography, which was strictly guarded by the West and Japan, was extremely important, but to Yu Hua, it was just an insignificant thing in his mind.
"Okay, it's up to you."
Fang Yu seemed a little disappointed when she heard that she couldn't go to class today, but she couldn't say anything. To be honest, she was lucky enough to get a place in the cartography class and she didn't dare to ask for anything too much.
Fang Yu is not a fool. She understands the meaning of Yu Hua's cartography ability, and she also understands how important this temporary cartography course specially offered to the two of them is.
This is her chance.
A hard-won opportunity must be cherished.
Don’t think that thirty yuan a class is very expensive. If you put it elsewhere, let alone thirty yuan a class, even a three hundred yuan class would be attended by people!
The most important thing is that no one talks about it at all.
People who can draw can’t explain it, and people who can’t draw don’t know how to explain it.
In fact, the seemingly high tuition fee is not comparable to the course content at all.
"As for the teaching of cartography, everything is up to you." Zhou Yuan heard Yu Hua's answer and nodded without making any comments.
"Then it's settled, I'll go do the cooking first."
Seeing that the two people with cash abilities had no objection, the matter was settled. Yu Hua picked up his rice cooker again, stood up and left his seat, said goodbye to Fang Yu and Zhou Yuan, and left the classroom to go to the cafeteria to cook.
People are like iron, and food is like steel. If you don't eat one meal, you will feel hungry.
The sky is big and the earth is big, dry food is the biggest.
"Huh? Wait, I seem to have one more thing I haven't done yet."
When he came to the corridor and walked a few steps, Yu Hua suddenly felt something was wrong. He seemed to have one thing that he had not yet settled. After thinking about it, he immediately understood what it was. He turned back to the classroom with some embarrassment and looked at Fang Yu, who had returned to his seat.
Asked: "By the way, classmate Fang Yu, do you still want to hear about the situation of portable lighting sources?"
It's a sin, it's a sin, I almost let another girl's dove go again.
Well, it doesn't matter whether she's a girl or not. The important thing is that Yu Hua forgot about the portable lighting source.
Establishing drawing standards is very important, earning teaching fees cannot be ignored, and making money from portable lighting sources cannot be given up.
Yu Hua hopes to get the key to the door to the girls' dormitory from Fang Yu, a young rich woman.
As one of the few girls in the Science Class 1, Fang Yu lived in Room 1A and 2 of the girls dormitory, where many girls from the Literature class lived.
The important step of hunger marketing is to obtain early orders, and only after the product is in the hands of customers and they experience it, and they feel really good, can we achieve the next step of arousing customers' desire to buy.
After the first day of warm-up, everyone in No. 4 Middle School has become aware of the portable lighting sources. Now, Yu Hua not only needs the original portable lighting sources from Room 2, Class 2 to seduce his classmates, but also needs a portable lighting source purchased by his classmates.
The official version of the light source equipment detonated the market.
When the market is detonated, the lovely and beautiful silver coins will splash into their pockets.
Yu Hua doesn't have too much money.
Fang Yu, who was packing her things, heard the sound and was stunned for a moment. She looked up at Yu Hua, who was a little embarrassed. She couldn't help but curl her mouth with a slight smile and said seriously: "I just want to take a look at what you made."
Whether the portable lighting source is suitable for our dormitory, it is enough to see this scratch paper today."
The mechanical structure diagram drawn by Yu Hua was not difficult to understand in essence. Fang Yu understood the secret after a little study.
The portable lighting system on the scratch paper meets the needs of their girls' dormitory.
PS: The power went out at 11:40 last night. When I woke up this morning, I saw that all the manuscripts were gone. When I re-wrote in the afternoon, my hands were shaking. The feeling of re-writing was really numb. Sorry, sorry, at the beginning of the month
I'm busy and have too many things at home, so I'll try my best to update as soon as possible.
