After settling the venue, Yang Quan and Liu Xiaokang helped all the parts move to the college. Yuan Qingli was deeply shocked after seeing Yang Quan's hand-drawn drawings for many days, he didn't expect Yang Quanneng to silently complete the drawing work of so many parts and components by himself.

Yang Quan was deeply influenced by RB drawings in his previous life, and the drawing annotation method also used the third-perspective method (marked with the "third angle method" in the lower right corner of the drawing frame), and China mainly used the first-view method, that is, the projection method.

There are hundreds of parts in an engine, and after removing the standard parts, Yang Quan can't paint the rest for a year. In such a short period of time, he has completed the drawings of more than 30 products.

To be honest, Yang Quan is extremely nostalgic for the era of CAD and 3D software. The computer crackled and operated, and the printed drawings were concise, clear and clear at a glance. Now you can only use the drawing tools bought from SH Pfeiffer Drawing Instrument Factory, and it is not easy to pack a complete set of tools in a box.

Although there are several computers in the school now, they are all placed in a special computer room like a baby. When the teacher is teaching, the students are carefully studying with shoe covers. The teaching content is also simple, that is, five strokes.

In the early 80s, the first upsurge of computer popularization was set off in China, and in 1981, CCTV, the Computer Popularization Committee of the Chinese Institute of Electronics and the Central University of Electrical Technology jointly held a lecture on the popularization of computer knowledge to teach the BASIC language to the whole country, and the number of viewers exceeded 1 million that year.

But what really made Yang Quan really serious about operating the computer was eighty-six years, and everyone in the school was seriously studying the five-stroke input method. And now, even if he has a computer, there is no drawing software that he can operate satisfactorily. Yang Quan remembers that in his previous life, he started using CAD drawing software in the early nineties, and I don't know if it has come out now.

In fact, in Yuan Qingli's view, Yang Quan's preliminary work is a bit of a snake. If it is just a 1:1 imitation of the 70CC engine of the motorcycle, it is the most time-saving to go directly to the original factory with the sample.

After arranging Yuan Qingli's next work, Yang Quan hurried back to Langya Auto Repair Factory. During Yang Quan's absence, the auto repair factory office has already shipped two batches of goods, and now the third batch of parts is about to arrive at the factory.

The two batches of goods brought Yang Quan a profit of 60,000 yuan, and Wujiacun Bicycle Factory is now receiving goods in large quantities, and it seems that Wu Hao is full of confidence in the mass production of pandas.

Yang Quan is going to talk to his uncle Zhou Aifu about the replacement of self-produced parts, Yang Quan plans to replace the products purchased from the construction and maintenance department, and gradually use the products in his hands, he thinks that he can prepare these works now.

Substitutions can be made by starting with simple and easy parts and working slowly.

Now I have 60,000 pieces on hand, which doesn't seem like much, but I can make several sets of molds. After going back and Zhou Aifu discussed the south to Zhejiang Province, the Pearl River Delta and the Yangtze River Delta as the center of the southeast coastal area developed faster than the central and western regions, Zhejiang Province three capital and private enterprises developed rapidly, mold is an important process basis for the manufacturing industry, the development of industry needs the support of mold.

Although China began to manufacture and use molds for a long time, it has not formed an industry for a long time. It was not until the late 80s of the 20th century that the mold industry entered the fast lane of development.

In 87 years, not only the state-owned mold enterprises have developed greatly, the development of individual mold enterprises is also quite good, but the strength of large-scale, precise, complex, long-life, high-grade molds and mold standard parts is still quite lacking, the level of molds and design and manufacturing level in general lags behind Germany, the United States, Japan, France, Italy and other industrially developed countries, and we need to continue to catch up.

Less than two hours after getting into the car, he returned home, and Zhou Aifu waited for Yang Quan's return at home.

"Uncle, are you sick?, why do you look dull on your face......" Yang Quan asked with concern. Yang Quan, who hadn't seen his uncle for half a month, smelled a smell of idleness and no direction in life from Zhou Aifu, compared with Zhou Aifu, who was in high spirits before the last parting, he seemed to be caught in a starless whirlpool of bare waste at this time.

"Er'er~, sit, we haven't been together for half a month," Zhou Aifu saw Yang Quan, lying on the sofa and lighting a cigarette. There was thirst in his hoarse voice, and bloodshot eyes were faintly visible.

Yang Quan picked up the teacup on the coffee table and poured a cup of hot tea for Zhou Aifu. The living room was replaced with a new sofa, and Yang Quan sat opposite and looked at Zhou Aifu.

"Uncle, what's wrong with you. ”

"I don't know what to do at home, I don't do anything every day. I feel bored with my current life, and I don't know what to do when I open my eyes from bed every day, these days, I'm idle and moldy!" Zhou Aifu lay on the sofa and spit out a smoke ring, his eyes were empty and he watched the smoke rings stack up and enlarge, and finally disappeared in the air.

"What about the factory, managing the assembly!" Yang Quan said worriedly, he was a little worried about Zhou Aifu's physical condition. "Didn't Qianqian say last time that she wanted to introduce their Chinese teacher to you?

"The big factories are all handed over to the big countries, and the factories of five people still have to be stared at every day?"

"Uncle, I came back this time to promote my own production of parts, I want to ...... with you"

Zhou Aifu lazily waved his hand to interrupt Yang Quan's words, took the last puff of the cigarette butt in his hand and pinched it out in the ashtray, holding his breath for two seconds before the gray white smoke rushed straight out of Zhou Aifu's nostrils.

"You don't have to ask me about the things that the factory does, to be honest, I'm not interested in setting up a factory to produce engines. At first, I wanted to see if your idea was as profitable as you said, but I didn't expect it to be the same as picking up money. However, there is no fun in making this money, I don't feel a trace of happiness, and it is even a kind of constraint for me, second, I am tired!" Zhou Aifu said in a calm tone from flat to excited and calm.

People who do factories and industries can calculate next year's sales this year, and at the beginning of the month, they can know the production plan of each month, and the payment will enter the account as if they were planning. Zhou Aifu turned from excitement to boredom at the beginning, this kind of day is a kind of torment for him, and the same thing is repeated every day to make him collapse.

"Er'er~, I'm going to go to Guangzhou after the National Day, the economic development over there is good, I and a few friends are going to go over to speculate on the house" Zhou Aifu spit out the idea that he had been holding back for a long time,

"At home, you will be in charge of the factory alone!"
