"Xiao Jiang, you pull the ruler to find a place of four meters, hold it and don't move!

Subtotal, don't move yet!

Xiao Liu, you find a position of seven meters, don't move!" Yu Qingyang commanded the three of them to use the Pythagorean theorem to turn at a right angle.

The Pythagorean theorem is understood by junior high school students, but it may not be so clear in practical application.

However, it is a layer of window paper, and there is nothing mysterious when it is pierced, and it is a very simple application of mathematical and geometric knowledge.

Xiao Jiang and the three of them were like puppets, instructed by Yu Qingyang, and used a tape measure to connect a right-angled triangle step by step.

"Oh...... So that's it!" It was only at this time that Xiao Jiang and the three suddenly realized that it was so simple.

"Yes, it's that simple!" Yu Qingyang said with a smile.

"Manager Yu, what do you do then?"

"Then just extend the line!

Follow this method and draw a rectangle on the field!

This is the foundation of our living quarters!

Then raise it with earth, compact, harden it, and build a house on top of it......"

"Brother Yu, is hardening concrete?"

"Yes, the whole area is concrete......"

Yu Qingyang took Xiao Jiang and the three of them to scatter gray lines in the living area.

Then Yu Qingyang took out his mobile phone, "Brother Lu, let your four dislike come and try to live!"

"Okay, I'm just waiting for you to say hello!" said Village Chief Lu with a smile.

Village Chief Lu is really interested, and he doesn't know how he does his work.

Really got twenty cars back, four is not like it.

Don't look at a village to raise funds to buy a car, it is not easy to get enough money for 20 cars!

Twenty cars are not like four, one million smaller.

"Hurry up and come here!" here at the mouth of the lake in your village!" Yu Qingyang also said with a smile.

After hanging up the phone, he explained to Xiao Jiang and them: "The three of you are responsible for keeping track of the number of cars!

We must resolutely refuse their unreasonable demands!"

"I know Brother Yu!, how do you count?"

"Draw orthography in the notebook, pull a car to draw a bar, and one of them will also count the number of cars with you!" Yu Qingyang explained to them carefully.

It's normal for students who have just graduated to not understand!

I think back then, when he first interned, he was not much better than them.

There is still some difference between the knowledge learned in books and the practical application, and someone needs to click on it in order to learn how to apply the knowledge learned in books to work.

It didn't take long, and Village Chief Lu rushed to the scene with people and four dissimilarities.

Village Chief Lu jumped off the four elephants, and asked arrogantly: "Brother Yu, what do you say!"

"Hehe, Brother Lu, are you still going to drive yourself?"

"Isn't this the first time I've done my job? I'll take them to practice for a day today!" said Village Chief Lu with a smile.

"Bring the earth from there to this place! Pour it into the gray line I scattered, three dollars a cart!"

"Okay, no problem!

By the way, this is the accountant of our village, you know, let him keep track of the number of cars with you!" said Village Chief Lu, pointing to a middle-aged man in his forties.

"Let's start!" Yu Qingyang nodded.

Village Chief Lu and his car were purchased by the village committee with funds, and the money earned was deducted from the driver's salary, and the rest of the village was divided according to the amount of capital contribution.

This saves Yu Qingyang and them, they don't need to record the number of cars separately, the invoice is so troublesome, just need to record the total number of cars.

Village Chief Lu climbed up to the four elephants, and drove to the position of the excavator.

These people are driving without a license, anyway, they are working in the river, and it is a technical job to overturn the car.

You just know how to put gear, how to put the gas pedal, how to put the steering wheel.

After driving it a few times, you will become familiar with it.

This is the same as driving tractors and agricultural tricycles in rural areas, and there are few people who apply for driver's licenses in accordance with the regulations.

Fourth, unlike this thing itself, it is not compliant, and it belongs to three no-vehicles.

That is, a good time of a few years, which will soon be eliminated.

These four are not like the products of the blank period of China's construction machinery, when the country is engaged in infrastructure construction, a supplement to domestic construction machinery.

The weight of the liberation trucks and Dongfeng trucks produced by the state is very small.

It is equivalent to a car like a Foton small truck in later generations.

It will not be until next year that domestic heavy-duty trucks will be on the market and gradually replace the four dissimilarities.

Yu Qingyang stood aside and watched for a while, waiting for everything to get on track before turning around and leaving.

Then I came to Lujia Village.

Yu Qingyang and the others live in Lujia Village, and the road construction is naturally the first to build the road in Lujia Village.

It's no wonder that people in their hometowns put forward opinions, good roads are crushed potholes, and there are ruts thirty or forty centimeters deep, all over the road.

Not to mention rainy days, even if it's good weather, it's not easy to walk.

The first step in road construction is naturally to level the roadbed.

Superintendent Liu Gong and others were also on the scene, repairing bridges and paving roads, which was a good thing to accumulate virtue and do good deeds in ancient times.

Supervisor Liu Gong and others stood on the side of the road, chatting with the villagers and accepting their thanks.

According to the villagers, this road has not been repaired for more than ten years, and the villagers usually take the shovel mat themselves.

Yu Qingyang: They used an excavator to repair the road, and the movement caused was really not small.

The old man and the old lady in the village, the eldest girl and the little daughter-in-law don't play cards anymore, they all stand on the side of the road and watch the excitement.

"This big guy is just working fast!"

"What is this called?"

"It's called an excavator! It's so energetic, it's so fast!"

"Otherwise, the people in the city have the ability, get such a big machine, our road is estimated to be repaired in a few days......"

Villagers stood on the side of the road and talked about it.

The children in the village also came to the front of the excavator to see the strangeness.

Although there were excavators when they were repairing the embankment before, they were all working on the embankment, and now they are working in front of their house, and these children are very excited.

Clustered in front of the excavator, giggling and playing.

These children, who don't know what to do, are very dangerous to laugh and play in front of the excavator.

Parents don't have this sense of danger, and they don't care about it, and it seems normal for children to fight.

Yu Qingyang hurriedly stepped forward and shouted: "Whose children, you guys stay away from the excavator!"

Hide to the side, I'll see who leans forward, I'll grab him and hand him over to your teacher!"

Yu Qingyang shouted, and the children who were playing in front of the excavator scattered and fled.

Teachers are still a great deterrent to children!

Driving away the children, Yu Qingyang said to the crowd watching the excitement: "Fellow villagers, uncles, aunts, uncles and aunts, brothers and sisters, it doesn't matter if you see the excitement, you must take care of your children!"

Don't let the child lean forward, you have also seen that such a hard road can be dug up, if it touches the body, the lightest will be a fracture!"

Then he explained to Xiao Shen and the others: "Xiao Shen, the three of you must take good care of you, not only to watch the excavator work, but also to pay attention to safety."

Don't let the kids move forward!"
