Seeing Huang Han tinkering with wires and things whose purpose he didn't know, Zhang Fangfen was shocked and said: "Don't mess around, it will be serious if you get electrocuted."

Huang Han said disapprovingly: "Don't worry, I'm not connected to the power supply at all. Where can I get electricity?"

"No, you are not allowed to play with this thing. I'm afraid! It's not like you haven't seen that 'one-armed boy' in Hedong. His arm was broken off by electricity. It's just because he was lucky that only his arm was burned off. Otherwise, the entire arm would be completely broken."

Everyone will be burnt."

"Mom, there's no need to be afraid. I'm not connected to the electricity at all. I'm pretending to look like a fluorescent lamp for you to see."

Huang Han quickly assembled the accessories on the wooden board that had been wrapped with white paper, and asked Cheng Wenge to tighten the screws with a screwdriver.

Zhang Fangfen looked at it and said, "It looks a bit like a fluorescent lamp, but it's completely different from other people's lamps. Can this thing be used?"

Obviously, Zhang Fangfen had seen fluorescent lamps with enamel shades, and could see the difference in the simple fluorescent lamps assembled by Huang Han.

Let her believe that there is basically no difference between this fluorescent lamp and the finished fluorescent lamp when used. It can only be convincing when it is connected to a power source and turned on.

But seeing Zhang Fangfen's awe of electricity, he definitely couldn't allow himself to climb onto the roof beams and connect the fluorescent lamps, so he had to get rid of her.

Huang Han said: "Mom, dad must know better than you. Wait until he comes back to see if this thing can be used."

"Well! If it works, you can ask the electrician from the briquette factory to come to your home to help install it."

Huang Han knew that he couldn't do anything at this time, so he simply pulled Cheng Wenge to sit down, took out the word problems and asked Cheng Wenge to start working on it.

Seeing that Zhang Fangfen was still watching, Huang Han prepared to play hard to get and said with a smile:

"Mom, Cheng Wenge and I are doing homework together. He will have dinner at my house at noon. You don't need to prepare anything specially. Just eat whatever you have at home."

Zhang Fangfen was very happy to hear Huang Han said that Chengwenge would stay at home for dinner, and said: "How can that be done? Chengwenge is a guest, so you can do your homework! I'll go out for a while."

Cheng Wenge realized that Zhang Fangfen was about to go out to buy groceries, and quickly said: "I, I, I didn't..."

Huang Han saw that he could send Zhang Fangfen away with a little trick, and he laughed secretly in his heart, pretending to be serious and said: "Chengwen Pavilion, you are not allowed to talk, you must do your homework seriously."

Chengwenge saw Huang Han winking and didn't know why, "You, you..."

Seeing Zhang Fangfen going out with a vegetable basket, Huang Han said: "Hurry up and start work."

"do what?"

"Install fluorescent lamps! Come on, let me borrow a ladder first!"

"Are you really going to install the fluorescent lights yourself?"

"of course it's true!"

"You, can you?"

"Don't be nagging. We'll see the results later. Now shut up and obey the order."

"oh!"

Huang Han led Cheng Wenge with a grimace to borrow a bamboo ladder from his neighbor Gu's house.

Under Huang Han's command, Chengwen Pavilion put the bamboo ladder on the second beam, and Huang Han was about to climb up the ladder.

Cheng Wenge suddenly said: "Huang Han, I'm scared too, please don't touch those wires, okay? What should I do if you get electrocuted?"

"Don't talk nonsense, the switch is not turned on, there is no electricity at all, where can I get electricity?

Be obedient, and it will be over in ten minutes. You have to help me hold the ladder, and be sure to hold it steady, otherwise I may break my leg."

"Oh! Slow down, be careful!" Cheng Wenge was very nervous, staring at Huang Han, for fear that he would fall.

Being small and light also has the advantage of being able to climb on the bamboo ladder and connect the wires very flexibly.

Zhang Fangfen went out for half an hour. When she came back, she bought a chicken, two large crucian carp, and three or four kinds of vegetables. She was shocked as soon as she entered the door.

Huang Han's house is an old house with small windows and poor lighting in the house. Huang Han installed the fluorescent lights and turned them on to prepare a surprise for Zhang Fangfen.

In fact, before Zhang Fangfen came back, Cheng Wenge was so surprised that the fluorescent lamps were turned on.

"Huang Han, you are so amazing. How could you do this? No, you lied to me. You just said that you were not connected to the electricity at all. Why is the fluorescent lamp on now?"

"I'm not lying to you. I didn't ask you to carry the ladder and accompany me to the electric meter just now."

"What's the meaning!"

"Didn't you see me turn on the white switch?"

"Saw it!"

"Pull down the switch to indicate a power outage, and close the switch to connect the power."

"Oh! I seem to have seen my father do this before. Why do you know how to connect electricity? You can also make your own fluorescent lamps, even my father can't do it."

"Study, you will only cry when you are born. After studying, you will master knowledge. But I want to remind you! Before you master the knowledge of electricity, you are not allowed to touch anything related to electricity."

"It goes without saying that I don't dare to touch you if you ask me. My father said that someone in the United Transport Company was electrocuted to death before. The death was ugly."

Following Huang Han's help, Cheng Wenge watched Huang Han put together a few messy things into a lit fluorescent lamp. Cheng Wenge was full of interest and concentrated on helping Huang Han tighten the screws to assemble the second lamp.

At this moment, Zhang Fangfen came in carrying a vegetable basket. She looked in disbelief and pointed at the fluorescent lamp and asked Huang Han: "Did you really install this? How do you know how to install a fluorescent lamp?"

Huang Han, who had already taken countermeasures, opened his junior high school physics book, pointed to the text on the principles of electric lights and said:

"Mom, the reason why we go to school is to study and learn knowledge. Why learn knowledge? Of course it is to apply what we learn. Look here, how to wire a light, it is clearly written in the book."

Zhang Fangfen was literate. She read the text carefully and felt it was like reading a book from heaven. Although she knew the content was related to electricity, she didn't know why.

"Can you understand everything written in the book?"

"Of course, why does everyone say that books have their own millenniums of millet, books have their own houses of gold, and books teach people to learn knowledge."

"You can install fluorescent lamps after reading the book?"

"Yes! Installing fluorescent lamps does not mean building two bombs and one star. As long as you don't stupidly read a book, you will understand."

Zhang Fangfen didn't quite believe it, but the fluorescent lamp was right in front of her, and she couldn't help but believe it. The expression on her face was extremely complicated, and then the fifth aunt walked in.

She just saw the bright lights in the main room of her third brother's house in front of her, and ran over to take a look, "Wow, the fluorescent lamps were installed so quickly! Is this the electrician? He's so young!"

Of course, the fifth aunt didn't know that Huang Han installed the fluorescent lamp himself. When she saw the tall Cheng Wenge, she thought he was an electrician.

Cheng Wenge was a little embarrassed. He was an honest man and was afraid of being misunderstood by others. He said: "Auntie, I am not an electrician. My name is Cheng Wenge. I am Huang Han's classmate. Today I just help tighten the screws and hold the ladder. The fluorescent lamp is yellow

Hanzhuang”

"Ah? Huang Han installed the fluorescent lamp by himself? Obediently, boom, don't die, Daowu, Daowu, come quickly!"

Huang Daowu's voice came, "What are you shouting about? People thought something happened when they heard it!"

"Take a look, what is this?"

"Nonsense, I don't recognize the fluorescent lamp? Hey, this fluorescent lamp looks a bit weird!"

"Huang Han pretended it himself!"

"What? Huang Han is pretending? Are you telling a joke?"

"I just saw him and this classmate Cheng carrying the ladder to the main hall, and now I know that they were going to pull the switch and install the fluorescent lamp."

"Isn't it possible? Huang Han, you really installed this fluorescent lamp!"
