This thing is silent? This made Old Gong very happy, "If it can really be silent, it would be great."
"You don't know, I also have an electric fan at home, but once it is turned on, it makes such a noise." Old Gong felt helpless when he thought of the noise every night.
But there is no way. If you don’t use an electric fan, it will be too hot at night.
"No matter what I say, it's useless. Once you use it, you'll know." Zhao Lei didn't want to say more. Whether something is good or not, you will know it once you have used it.
Zhao Lei quickly installed the electric fan and then turned it on.
When the fan started working, there was no noise, which made Mr. Gong very happy, "This thing is really good."
"With this, I can have a good rest in the summer." In the summer, the temperature is high and the appetite is poor. If you can't have a good rest, it will be very harmful to your health.
Even if the fan made a loud noise, Mr. Gong could only endure it, at least there was wind.
"Not to say there is no sound, as long as it is low noise." At least it allows him to rest better.
Unexpectedly, the electric fan Zhao Lei made was really good. "How much does this cost?"
Mr. Gong habitually wants to calculate the cost. If the price is right, he will promote it quickly.
Zhao Lei remembered the cost of these things, and calculated them one by one. As for the total amount, he let Lao Gong calculate it himself.
Old Gong quickly took out a pen and paper and started to do calculations. After a while, Old Gong covered his chest with his hands again.
"Really? I didn't expect it to be so cheap." Old Gong thought that this motor was better and should have been replaced.
Unexpectedly, it is a bit expensive, but not as outrageous as the original.
“Once the production volume increases, the price should come down.” Zhao Lei couldn’t be sure whether this was true or not, but it had nothing to do with him.
"Okay, I've given you the things, you can go now." Seeing that it was getting late, Zhao Lei asked him to leave quickly.
When Old Gong saw how impatient Zhao Lei was to get him out, he knew it was almost time to get off work.
"No, I'm leaving." He packed the things gently. Although he knew it would be the same whether he packed them or not, it would definitely attract the attention of those who have ulterior motives. As long as he didn't say it, some people would be upset.
"Well, I can go now. You have already researched the modern electric fan. What are you going to research next?" I really want to know.
What to study next? Zhao Lei really hadn't considered this, such as washing machines. According to his wife, these things would definitely be convenient for housewives.
"I thought, winter is coming soon, and there will be more children at home, so there will be a lot of laundry. I wondered whether I should go out and do some laundry."
"Well, washing machines." Zhao Lei didn't know when washing machines first appeared, but it didn't matter. Since there were none in China now, he could operate it.
Washing machine? "It's used for washing clothes. Can't I ask my wife to wash them?" Mr. Gong thought of his own clothes, which were all washed by his wife.
Zhao Lei glanced at Lao Gong, "Yes, your wife does the washing at home. Lao Gong, why don't you think about your wife? In the middle of winter, she washes clothes and quilts. Don't you know that water is cold in winter?"
"That can be done with hot water." Old Gong knew that most people used cold water to wash clothes and were reluctant to add hot water.
"If you add more hot water, it will be cold in a short time in such a cold weather." Zhao Lei concluded, "Old Gong, I can see that you are not a loving wife."
