After recovering 4.5 yuan in arrears from Qin Huairu, Li Weidong had a total of 20.7 yuan in money.
This money is enough to do a big business.
Out of the courtyard.
There are houses built with blue bricks on both sides of the street, and there are rough slogans painted in white and gray on the walls.
Pedestrians were wearing thick cotton-padded jackets, tattered felt hats, and cotton masks, breathing out white air.
Most of the pedestrians are walking, and occasionally you can see a decent man wearing a gray tunic suit and his hair parted in the middle riding a bicycle.
Although it is not as prosperous as later generations, it still has a peaceful and progressive atmosphere.
This smell made Li Weidong energetic, and he strode towards the chemical materials store five miles away.
Of course, there are also buses passing by on the road.
It's not the same as the buses of later generations.
There is a huge gas storage bag on the roof of the car, which is jokingly called the "big gas bag".
Due to the shortage of supplies, buses in this era were forced to install stoves to burn charcoal or wood.
The gas produced by combustion replaces gasoline and provides power for the normal driving of the bus.
You have to buy a ticket to take the bus, and Li Weidong is reluctant to spend the money.
The chemical raw materials store is located on Qianmen Street.
It starts from the Qianmen Arrow Tower in the north and ends at the Tianqiao intersection in the south, where it is connected to Tianqiao South Street.
There is a jingle in the old capital, which is: East, four, and west, in front of the drum tower.
In the old days, these places were bustling commercial districts bustling with tourists, and the busiest among them 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 seed market, etc.
There are also some theaters, tea gardens, etc.
Although these shops have now been nationalized, only the nature of their business has changed, and the main body of the building has not changed in any way.
Among the green trees, there are hundreds of buildings of different styles, which look quite luxurious.
By the time I arrived at the chemical raw materials store, I was already thriving.
As soon as he entered the door, Sister Niu, the salesperson 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 playfully.
"De Xing, now you have learned to speak glibly." Sister Niu tossed a bag of copper ore powder to a gay man wearing black-rimmed glasses and exuding a refined aura.
Ignoring the gay man's request to weigh himself, he stood up and waved to Li Weidong.
"Weidong, I heard that your father passed away."
"Yes, it happened not long ago."
"Then are you going back to the sales department? How about I go and tell the section chief?" Sister Niu was a little reluctant to let go of Li Weidong.
This young man works hard and is not lazy.
One person can serve two purposes.
Every time I get off work, I help clean up the counter.
With him around, Sister Niu doesn't have to worry when encountering heavier materials.
It's not like the new guy, who I heard is a relative of the deputy section chief, hides in the warehouse all day long and chats with those old ladies.
"No, in two days I will take over my father's shift and work as a truck driver in the third rolling mill fleet." Li Weidong said gratefully.
"That's a good job. I heard that truck drivers can get this amount every month." Sister Niu slapped her, her eyes lit up immediately, and she lowered her voice: "You don't seem to be married yet. I have a niece.
, I work in a textile factory, and I look like a flower. How about I help you pull the thread?"
Li Weidong declined politely: "Thank you, Sister Niu, I already have a partner."
"What a pity. What a pity." Sister Niu looked regretful.
If he had known 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 found the person he was waiting for.
I saw three young men wearing black uniforms, with pictures on their chests and black shallow-brimmed hats walking in, talking and laughing.
"Hu Guangliang, people in Shanghai are beginning to install tube radios. The ore radio is out of date. It can only receive one station. When the station is stopped, you can only hear the sound of electricity. You can give it to the ore radio.
If you give leaves as a gift, people will dislike it."
"If I want a tube radio, I can just go to the department store and buy one. Let me tell you, this time Ye Zi followed Professor Wang to the northwest for prospecting. The place is remote and it is not convenient to buy batteries. I just thought about it.
Make an ore machine and give it to her."
"Gao, Gao Ming, Lao Hu is very clever at taking pictures of his mother-in-law. My brother admires him very much."
"Don't lie, the relationship between me and Ye Zi is pure."
"Lao Hu, you are just too shallow-skinned. In this new society, it is normal for men and women to fall in love."
...
Li Weidong turned around, a joyful look flashed in his dark eyes.
The three people who came in were college students from the Physics Department of Qinghua University, and they were also fans of the 'Ore Machine'.
The 'Ore Machine' is a radio receiver without power supply that uses ore for detection and a tuning circuit.
Ore machines can be assembled by hand due to their low cost.
It does not require batteries, can be used for life, and has no maintenance costs. It is very popular among people.
The ore machine had so many advantages, but it was not popularized in the subsequent period, and it also had fatal shortcomings.
Natural ores require patience to find sensitive points before they can receive radio signals, and not every piece of 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 enthusiasts.
In an era when a radio was worth the price of a car, those who could afford radios were educated and had some money.
For example, Hu Guangliang.
When Li Weidong was working as a temporary worker, Hu Guangliang often came to buy raw materials for the ore machine.
After going back and forth, the two became familiar with each other.
I know 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 more importantly is the letter of introduction for the purchase of chemical materials.
Just like buying grain requires food stamps; buying meat requires meat stamps; buying old hens requires poultry stamps; buying bicycles requires bicycle stamps; buying toothpaste, steel pots, enamel basins, flashlights and other industrial products requires industrial coupons.
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 require a letter of introduction from the unit before they can be purchased at chemical raw material stores.
arrive.
Ordinary people have no way at all.
This is also the reason why Li Weidong is waiting for these three Qinghua college students.
They are members of the Qinghua Physical Radio Experiment Group and have letters of introduction issued by Qinghua University.
"Sister, please come to a group first according to the materials on the list." Hu Guangliang took out the letter of introduction, waved 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 he spent, he would help Ye Zi assemble an ore machine that could receive broadcast programs from the capital.
"Okay, just wait a moment."
They are all familiar customers. These Qinghua college students have spent four to five hundred yuan here. Sister Niu didn't even read the letter of introduction. She took the list and prepared to go to the warehouse to pick up the materials.
As soon as she walked out of the counter, she was stopped by Li Weidong: "Sister Niu, I'm free anyway and I'm familiar with the warehouse, so just let me go."
"Okay, sister will treat you to dinner at noon, and call my niece by the way." Sister Niu was eager for someone to help, so she joked.
