Comfortable life in Siheyuan

Sha Zhu didn't think about Tian Xiuyun going out to work, but Yu Shui brought it up, and it was still an unknown, so he just went along with it and didn't object.

"Qingshan, I have to go to work. What about Xixi? We both have to go to work, and we can't leave the child at home alone!" Feng Yu said.

No one in Liu Qingshan's family has reached retirement age, and there is no one to take care of the children now.

"Now Shitou has been admitted to a technical secondary school. Your mother is at home during the day. Why don't we send you to her place during the day in the future?" Liu Qingshan asked.

"Let's take Xixi back and ask tomorrow. I think there should be no problem. We just need to pick her up in the morning and evening. It's not far anyway, and it's not a big deal." Feng Yu said after thinking for a while.

"Okay, I'll go ask tomorrow. But what about the baby's breastfeeding? Are you free to come back every day to feed the baby?" Liu Qingshan asked.

"I can come back at noon." Feng Yu said.

"Stop struggling with this, both of you. Just leave the children with me when you're at work. I can feed one or two," said Tian Xiuyun.

"That's right. My wife can take care of the children at home now, and the two children will have a companion. I suggest that Xixi become my daughter-in-law in the future." Sha Zhu laughed.

You're dreaming. Liu Qingshan rolled his eyes.

"You should still let your mother come over. It's not convenient for Sister Xiuyun to take care of two children alone, and it will be difficult for her to cook." Liu Qingshan said.

"Well, thank you Sister Xiuyun. Let's go back tomorrow." Feng Yu said.

"There's no need for our two families to be so distant and estranged," said Tian Xiuyun.

They played until dinner time before going back home. During the game, Tian Xiuyun even brought a bowl of fish soup to the deaf old lady.

The next night, Liu Qingshan took his wife and children to his father-in-law's house.

Liu Qingshan pushed the bicycle and Feng Yu carried Xixi into the house.

"Dad, Mom, we're back." Feng Yu shouted loudly.

"Oh, Xixi, do you miss grandma?" The mother-in-law came over and hugged Xixi.

"Mom, Qingshan and I came back because I want you to help take care of Xixi. I'm going to work in two days, and I want you to go to my house to help take care of the child." Feng Yu said.

"Yes, Mom and Dad, there is someone in our hospital who can help take care of the child, and she has a child of her own. So I would like to ask you to come over and help." Liu Qingshan said with a smile.

"What's the big deal? Mom has nothing to do at home. I'll go over there after breakfast every day. Xiaolei doesn't come back often, and I'm bored at home. It's a good opportunity for me to accompany our Xixi." The mother-in-law replied with a smile.

"Yes, you don't have to worry. Your mother will go and help look after you during the day. It's no big deal. We are all family." said the father-in-law.

"Thank you, Dad, thank you, Mom." Liu Qingshan said.

After finishing their business, the two chatted for a while at home and then went home.

...

Xiaoyu officially went to work today, and Liu Qingshan went to pick up his mother-in-law early in the morning.

"Mom, this is sister-in-law Xiuyun. Her child is one month older than Xixi. He will be with Xixi from now on, so I'll have to trouble sister Xiuyun. You just need to help sister Xiuyun take care of the child." Liu Qingshan said.

"Sorry to trouble you, sister-in-law." Feng Yu said.

"You're welcome." Tian Xiuyun said with a smile.

After arranging the household affairs, Liu Qingshan sent Xiaoyu to work. Before leaving, he left the car to Xiaoyu. He would come back to feed her at noon every day.

Liu Qingshan walked to work by himself.

Liu Qingshan watched the security guard at the door conducting body searches on several workers who were leaving the house, and an idea popped into his mind.

I went back to the office and put the work aside.

I took out the blueprint and drew a simple circuit.

The image of the metal sensor appeared in Liu Qingshan's mind.

I have seen this thing many times in my previous life. Every time I enter a high-speed railway station, there is a detection gate. That one is much more complicated than what Liu Qingshan drew. Liu Qingshan just drew a basic electromagnetic induction circuit.

Then, in the morning, he went to the electrician class, got a multimeter and modified it into a simple metal sensing instrument.

After doing all this, I went to find Mr. Zhang first.

Mr. Zhang was very interested in what Liu Qingshan made.

"Qingshan, why did you think of doing this?" asked Mr. Zhang.

"Mr. Zhang, I thought of this this morning when I saw the security guard at the gate reclining. Workers in our factory sometimes secretly take some scrap steel or workpieces out to sell, and we have been caught many times.

I thought about doing something to reduce the workload of the security guards. After all, there are a lot of people coming in after get off work, and it is not realistic to search them one by one. It can also prevent enemy agents from causing damage. "

Mr. Zhang thought about it and thought this was a good idea.

Metal detectors are not unfamiliar.

If it can be modified, it can be of great use.

Immediately, Engineer Zhang found Section Chief Qin and told him about the matter.

The entire technical department was discussing this in the afternoon.

"We can make a handheld one and hold it in our hands to conduct focused searches on certain individuals," said Tang Xiaoling.

"Yes, we can also make a big one and turn it into a small door, and everyone can go through the small door." Liu Qingshan said.

“An indicator light can be installed to give an alarm. It will give an indication as soon as metal passes by.” Wang Lei also said.

"You can also install a speaker, and it will make a sound when metal passes through." Brother Li Li Changhai also said!

"Yes, you all have good ideas. Let's make one first. This thing has many application scenarios. It can be of great use in confidential units, bus stations, train stations, airports, and important security locations." said Section Chief Qin.

"Okay, let's get this out today. Once it's done, we'll go try it with the security guard." said Engineer Zhang.

The technical department brainstormed, and with Liu Qingshan's advanced vision, a special door that was not very beautiful was soon completed. Because it was a test product, no one cared about the appearance and size.

When it was time to get off work at the steel mill, everyone was surprised to see something like a small door at the entrance of the steel mill.

The gates of the steel mill were still closed.

Everyone had to go through this small door after get off work. Even the factory manager stood here and looked at this small door curiously.

After waiting for a while, a worker passed by and the red light on the small door came on, and there was a beeping sound.

The security personnel quickly asked what metal objects he was carrying.

The man took out a bunch of keys tremblingly.

It was a false alarm, but it did prove that the instrument was effective.

After a while, a worker who stole parts was finally caught.

The factory manager walked around the door for a long time but ignored the worker who stole the parts.

A group of people in the technical department also kept recording some places that could be modified and adjusted.

Finally, all the workers left their shift.

The security department counted and found that in just half an hour, they caught four people who stole spare parts and three people who stole scrap steel. The results were remarkable.

Director Yang said that he would write a detailed report tomorrow and make another one. He would bring the materials and the actual objects to report to the department.
