Black-and-white televisions are inherently complex in terms of internal parts.

It's not because it's more advanced, on the contrary, the principle of a black-and-white TV is simple, so it requires a lot of basic parts to cooperate with each other to achieve the effect of playing the picture.

If you change to the extremely thin TV set in the previous life, because there has been a technical breakthrough in the display screen, all the parts needed in the black and white TV are eliminated and directly replaced with light and simple chips.

This is the development of science and technology, the more advanced the technology, the fewer parts that need to be used.

However, Su Yi has an intimate sense of black-and-white televisions, and these appliances, no matter what generation they develop, are precious achievements for her.

Su Yi indulged in repairing electrical appliances.

Even Su Jinnian and Lin Xiu didn't know that they were back.

As soon as she finished repairing a TV, she looked up and saw Su Jinnian also sitting next to her, holding another repair.

"Dad, when are you coming back?" Su Yi rubbed her eyes and looked outside, only to know that it was dark, and she vaguely remembered that someone seemed to have helped her turn on the light.

She was cultivating the most critical position at the time, so she answered casually.

"It's up to you to repair here when you come back, go to bed early at night, and the rest of your dad will come." Su Jinnian said while repairing.

"By the way, there are oranges cut by your eldest brother for you, poured malt milk essence, eat less, and there will be boiled fish to eat in the evening. ”

Su Yi stretched his waist, turned his head, and sure enough, he saw cut oranges and soaked malt milk essence on the table.

After eating a piece of orange and drinking water, it was cold, and she really felt that she had forgotten to eat and sleep.

Had dinner.

Lin Xiu boiled water to bathe Su Jinnian, he now works every day, he has to sweat several times during the day, and he can't take a bath at night.

Su Yi is in the warehouse to choose a more suitable radio.

Su Soon-woo writes homework.

Su Shunlin counted the money beside him.

"Big brother, I didn't expect that one day we could make money by selling test papers, we brought over forty-five test papers at noon, and all of them were sold out, a total of thirteen yuan and five!"

"The book was sent back by my uncle, should we have one copy for each of us this time?" asked Su Shunlin.

"Give my uncle a little more this time. Su Shunyu groaned and said: "My uncle is injured, he has been spending money in the hospital, he must be uncomfortable, let him know that he can make money by selling test papers, he has something to do, and he doesn't have to think nonsense." ”

"Okay, big brother, you have the final say. Su Shunlin didn't understand that much, if Su Shunyu hadn't said this, he would definitely not have thought of it before.

"Then give half to my brother-in-law, and the two of us will divide it equally. ”

Even so, he would get three dollars, the most he'd ever gotten.

"Big brother, I still have to copy the test papers!" Su Shunyu took his three yuan and grinned, not to mention how happy he was, this was more pleasant than eating a bowl of meat.

"That's my own money. Su Shunlin laughed.

Su Shunyu put away his share indifferently, although he didn't see anything he revealed, he could also see that he was in a good mood.

At night, Su Shunlin didn't go to bed until ten o'clock.

The lights in the house were on for a long time.

Lin Xiu finished cleaning up, went to see Su Yi, and saw that she had already fallen asleep, so she went back to the house, wearing a thin underwear, and sat on the bed: "Shunyu, they are almost crazy about selling test papers recently, and they are still copying at night." ”

"When I get a chance to ask about the printing press, if I can find one back, they can make it easier. ”
