Siheyuan: Start with a big car

Chapter 7 Chemical Raw Materials Stores
The 4.5 yuan owed was recovered from Qin Huairu, and Li Weidong had a full 20.7 yuan of money.

That's enough money to do a great job.

Out of the courtyard.

On both sides of the street are houses built with blue bricks, and there are rough slogans painted with whitewash on the walls.

Pedestrians were wearing thick padded jackets and torn felt hats, and cotton masks, breathing heavily.

Most of the pedestrians are on foot, and occasionally a decent man in a gray tunic with a parted hair can be seen passing by on a bicycle.

Although it does not have the bustling bustle of later generations, it does not have a peaceful and progressive atmosphere.

This breath made Li Weidong full of energy, and he strode to the chemical materials store five miles away.

Of course, there are also buses passing by on the road.

It is not the same as the bus of later generations.

There is a huge gas storage bag on the roof, which is ridiculed as a "big bag".

Supplies are scarce, and buses in this era are forced to be equipped with stoves to burn charcoal or wood.

The gas produced by the combustion replaces gasoline and provides power for the normal running of the bus.

Li Weidong was reluctant to spend the money to buy a ticket to take the bus.

The chemical raw material store is located on Qianmen Street.

It starts from Qianmen Archery Tower in the north and reaches Tianqiao intersection in the south, connecting with Tianqiao South Street.

There is a jingle in the old capital called: East, West, and Drum Tower.

In the old days, these places were bustling business districts full of tourists, and the most prosperous one was Qianmen Street.

Before liberation, there were many professional markets here.

Such as fresh fish market, meat market, fruit market, cloth market, grass market, pig market, grain market, jewelry market, melon seeds market, etc.

There are also some theaters, tea gardens and so on.

Although these shops have been nationalized now, only the operating nature has been changed, and the main body of the building has not changed.

Among the green trees, there are hundreds of buildings of different styles, which look quite luxurious.

When I arrived at the chemical raw material store, the sun was already rising.

As soon as he entered the door, the saleswoman Niu Dajie who was sitting behind the counter greeted Li Weidong with a smile: "Weidong, why are you so free today, are you here to see my sister?"

"Yeah, I've been away from the store for more than a month, and I miss you so much." Li Weidong smiled hippie.

"Virtue, now I've learned to be glib." Sister Niu casually threw a bag of copper ore powder to a gay man wearing black-rimmed glasses and exuding a gentle aura.

Ignoring the gay man's request to be weighed, he stood up and waved to Li Weidong.

"Weidong, sister heard that your father passed away."

"Yeah, it was just a while ago."

"Then are you still going back to the sales department? How about I tell the section chief?" Sister Niu was a little bit reluctant to part with Li Weidong.

This young man works hard and is not lazy.

One person can handle two.

Every time I was about to get off work, I also helped tidy up the counter.

With him around, Sister Niu doesn't have to worry about heavy materials.

Unlike the new guy who is said to be a relative of the deputy section chief, he hides in the warehouse all day long, chatting with those old ladies.

"No, I'll pick up my father's shift in two days and work as a truck driver in the fleet of the third rolling mill." Li Weidong said gratefully.

"That's a good job. I heard that truck drivers can get this amount every month." Sister Niu stretched out her hand, her eyes lit up immediately, and she lowered her voice: "You don't seem to be married yet. I have a niece , working in a textile factory, people look like flowers, or else, I'll help you pull the thread."

Li Weidong politely refused: "Thank you, Sister Niu, I already have a partner."

"It's a pity. It's a pity." Sister Niu looked regretful.

If he knew that Li Weidong could take over from his old man, he would have introduced his niece to him long ago.

The two chatted for a while, and Li Weidong finally got the person he was waiting for.

Three young men in black uniforms with portraits pinned to their chests and black shallow-brimmed hats came in talking and laughing.

"Hu Guangliang, tube radios are now installed in the magic capital. The ore machine is outdated, and you can only receive one station. When the station is stopped, you can only hear the sound of sizzling electric current. You take the ore machine to If leaves are used as gifts, people will despise them."

"If you want a tube radio, I can go to the department store and buy one. Let me tell you, this time Ye Ye followed Professor Wang to the northwest for prospecting. It's remote and it's inconvenient to buy batteries. I just thought Make an ore machine and give it to her."

"Gao, Gao Ming, Lao Hu's kung fu in filming his mother-in-law is brilliant, my brother admires him very much."

"Don't talk nonsense, the relationship between me and Ye Zi is pure."

"Old Hu, you are just too shallow-skinned. Now it's a new society, and it's normal for men and women to fall in love."

Li Weidong turned around, a look of joy flashed in his dark eyes.

The three people who came in were college students from the Physics Department of Tsinghua University, and they were also lovers of the 'Ore Machine'.

'Ore machine' is a radio receiver that has no power supply, uses ore for detection, and a tuning circuit.

The ore machine can be assembled by hand due to its low cost.

It does not require batteries, can be used for a lifetime, and is free of maintenance costs. It is very popular among the public.

The ore machine has so many advantages, but it has not been popularized in the following time, and it also has fatal shortcomings.

Natural ore needs to be patient to find a sensitive point before it can receive radio signals, and not every ore can be used.

It often happens that a lot of ore is purchased and a lot of materials are wasted, but the ore machine cannot receive the signal.

In this way, the technical threshold for making ore machines has been raised.

Most people who make ore machines are radio amateurs.

In an era when a radio was worth a car, those who could afford it were educated and had some money.

Such as Hu Guangliang.

When Li Weidong was a temporary worker, Hu Guangliang often came to buy raw materials for ore machines.

After going back and forth, the two are considered familiar.

It is known that he was born in a military compound.

The two people next to him also came from the ministry compound.

Money is one aspect, but what is more critical is the letter of introduction for purchasing chemical materials.

It is like buying food coupons for food; meat coupons for meat; poultry coupons for old hens; bicycle tickets for bicycles; industrial coupons for industrial products such as toothpaste, steel pots, enamel pots, and flashlights.

The ores, capacitors (2200 picofarads), high-impedance headphones, 2AP9 diodes, 1N60 diodes, enameled wires, wires, variable capacitors and other materials needed to assemble the ore machine are controlled materials, and you need a letter of introduction from the unit before you can buy them at the chemical raw material store. arrive.

Ordinary people have no way at all.

This is why Li Weidong waited for these three Qinghua college students.

They are members of the Tsinghua Physical Radio Experiment Group, and they have a letter of introduction issued by Tsinghua University.

"Sister, come to the group first according to the materials on the list." Hu Guangliang took out the letter of introduction, shook it on the counter, and handed the list to Sister Niu.

The ore machine is extremely difficult to make and often fails.

He made up his mind today that no matter how much money it costs, he must help Ye Zi assemble a mining machine that can receive radio programs from the capital.

"Okay, wait a minute."

They are all familiar customers. These Qinghua college students spent four to five hundred yuan here. Sister Niu didn't read the letter of introduction, so she took the list and prepared to go to the warehouse to pick up materials.

As soon as she walked out of the counter, she was stopped by Li Weidong: "Sister Niu, I'm idle anyway, and I'm familiar with the warehouse, so let me go."

"Okay, Sister Noon invites you to dinner, and by the way, call my niece." Sister Niu joked, eager for help.
