ps: Thank you for the tips of the three hardcore girls joycf, r, and a housegirl in Jiangnan. There's another chapter coming up, so wait a minute.

Chu Jiaqiang didn't sit for long, and the village chief of Shuanghe Village also came to the door. This village chief is also relatively old, and in backward villages like theirs, the village chief is generally a respected old man.

"Old Zhong, how is my sister-in-law now? Is it better? Village Chief Huang greeted with concern. The population of the village is not very large, so every time something happens to the family, the village chief will be more concerned.

The second aunt's old father poured a cup of tea: "The old problem, Brother Chu will get better after a massage." ”

"It's okay, we old bones don't recognize old guys! Brother Chu, you haven't been to our village for a long time, have you? Studying in college is indeed different, and now that you are out, you Chujiazhai is blessed! Village Chief Huang sighed at the end.

He regretted in his heart that such a promising young man was not from his own village. You must know that Chujiazhai was not better than their Shuanghe Village before, but now it is different.

"Huh! Actually, our Shuanghe Village is not the same as his blessing? Otherwise, our road will probably be the same in five years. The second aunt's old father smiled. Of course, the most relatives in the village are his family, so the most cheap is also his family. In the past year, his daughter and son-in-law have helped their family too much.

In fact, it is not only a road problem, because of Chu Jiaqiang's relationship, it is now much more convenient and expensive to sell agricultural products in the whole town, and people with good craftsmanship also mix well with handicraft.

Village Chief Huang stroked his beard and nodded with a smile: "That's right, our whole town, especially the villages near Chujiazhai, are really cheap, and even we are red-eyed." ”

Not only their eyes are red in Shuanghe Village, but also in other villages in Heqian Town. So Village Chief Huang is not afraid to confess. Seeing that the family with an annual income of 10,000 or thousands suddenly increased several times, or even more than ten times, who is not jealous?

Chu Jiaqiang smiled bitterly: "Everyone has been promoted, mainly by everyone's efforts, I am just promoting." ”

After chatting for a while, when it was time to eat, Village Chief Huang said goodbye and did not stay to eat. And he still has something. The village pulled back two cement telephone poles to connect the wires to the west, and three families were going to build houses there, so they pulled them in advance.

After eating, the second aunt's child wanted to take the car. I didn't dare to tell the adults in the family, but I secretly spoke to my kind aunt. The second aunt had no choice but to let Chu Jiaqiang drive a few of them out for a walk, anyway, Chu Jiaqiang has nothing to do now.

When the children of other families saw it, they were envious. I went out of the village and came back after two circles, so that the children could have fun. When I returned to the village, I saw some men in the village gathered together. Village Chief Huang was also there, directing two people to dig a pit. There is a telephone pole on the side.

Looking a little farther away, I saw that another cement pillar had been erected, and there was a half-bundle of cables. These are all provided by the power supply in the town, otherwise in the character of the rural people. Expensive cement poles will never be pulled back, just replace them with wooden poles.

Among them, a worker in a power station costume is climbing up to fix his body. Install a tripod on top that holds the wires in place.

There was nothing to do when he came back left and right, after Chu Jiaqiang parked the car. I also walked over to join in the fun. As soon as he walked over, many people greeted him.

"The God of Wealth has arrived, it seems that our village is now in operation." A middle-aged man joked.

Chu Jiaqiang said politely and greeted the people who greeted him. Looking closer, the pit has been dug half a meter deep, and the pits of these electric poles are generally more than one meter deep to be more secure.

"Don't you need to pull the wire to fix it?" Chu Jiaqiang asked.

In some places, in order to ensure that the pole is not tilted, a wire will be pulled in three directions on the pole to fix it. Otherwise, the pole may be fine for a short time, but after a few years, it will be obviously tilted to the stressed side.

"The person at the power supply station said no, there are few wires on it, and it will be fine. Dig a little deeper, though. Village Chief Huang explained. In fact, in the final analysis, it is still about saving.

Children are always a group of curious babies, with a lot of questions, seeing a few birds standing on the wire, and not understanding why the birds are not electrocuted.

One child innocently guessed: "I know, the bird's claws have a layer of skin, and it will definitely not be electrocuted!" ”

The adults pouted: "You also have a layer of skin, go try it?" ”

Village Chief Huang glared at the man: "Don't joke with the children, they are not sensible, maybe they are really angry to touch it, are you responsible?" You little guys have listened well, don't touch the wires casually in the future, and you will shed your skin if you don't die. ”

"Hehe, because the birds only stand on one wire, and if they step on one foot, they will be electrified." Chu Jiaqiang explained to the child.

"Is it true that if I go and catch a wire, it won't be electrified?" As soon as Chu Jiaqiang finished speaking, an elf child asked.

Chu Jiaqiang was slightly stunned, and then shook his head: "You have to listen to your village chief grandfather, and don't touch the wires casually in the future." The situation of people is different from that of birds, which do not touch the ground. In the future, you have to read carefully, and you will know why the birds will not be electrified. ”

He also explained too much that too advanced knowledge is not something that these children can understand, and when they go to junior high school, they will naturally understand when they are exposed to physics.

Electricity is divided into positive and negative poles. When a conductor is connected between the positive and negative poles, an electric current flows through the conductor. Similarly, wires are also divided into positive and negative wires. The human body is a conductor, the human body is larger, when it touches the wire, the two wires are connected together, forming a short circuit, and there is a large current flowing through the human body, which is the reason for the electrocution of the person. Due to the small size of the bird, it only touches one wire, its body and the wire it is standing on are equipotential, and there is no electric current passing through the body, so they will not be electrocuted.

However, if the snake climbs on the power line, it is dangerous, its body is long, and when it climbs on the high voltage line, it will connect the positive and negative two together, causing electrocution. Rats that burrow into power distribution rooms are also often electrocuted to death.

We also know that the live operation of electrical workers on high-voltage lines is the same as that of a bird standing on a wire, so it can be operated safely. Birds such as magpies and crows like to nest on telephone poles, which is also very dangerous, which can easily form short circuits and cause disasters.

Seeing Chu Jiaqiang educating the child like this, Village Chief Huang nodded, and secretly thought: Intellectuals who have read books are different, Chunchun induces.

"Got it? You must study hard and learn from your strong uncle. "Village Chief Huang has high hopes for the children. I hope that these boys and girls can come up with a character as good as Chu Jiaqiang and benefit their village.
