Zhang Xian was packing up with his grandmother.

"You're moving?"

"Yes, we have something to go back to. ”

Seeing that the grandparents and grandchildren needed to bring a lot of things, it was difficult to choose, so Tian Tian said, "I'll drive you in my car." ”

"You have a car? That's great, we're worried about too many things to have! We can pay you the fare. ”

"!" Tian Tian said.

"Are you helping for nothing? There are still a lot of good people in society. The old woman said.

"Hmm. The secretary of our school issued an initiative for all students to do good deeds, and many people responded!"

"That's a lot, there's so much to do. Tian Tian said.

"Isn't it better to do good deeds?" Zhang Xian said.

Driving on the road, Tian Tian said to Zhang Xian again: "Which class are you? I also went to the second high school." ”

"Really, we're alumni!"

"I've also had a table with Chen Tiedan. The tablemate's name is Chen Yaya. ”

"I know Yaya, and they have come to my house to help others. ”

"They're here too?!" Tian Tian subconsciously stepped on the brakes - do you want to go?

"That was three years ago, and now they're gone. ”

"Oh, that's ok. Tian Tian continued to step on the accelerator.

When he arrived at Zhang Xian's hometown, Tian Tian looked at the courtyard and said, "The elderly like the courtyard of the farmhouse, but it's too dilapidated here, right?"

Zhang Xian didn't have time to pay attention to her, so he took a bag of Bai Dongdong and put it in the place where the sun was poisoned.

"What is this?" wondered.

"It's a mushroom — it's actually an oyster mushroom, and everybody calls it a mushroom. ”

Sure enough, I saw that there were already oyster mushrooms growing.

Zhang Xian tore off the plastic film on the outside of the bag, put the mycelium on the ground, and splashed it with cold water.

"You're acting too roughly, aren't you?" Tian Tian said.

"I'm going to train it, use it to make strains and make mother seeds. Zhang Xian replied.

Then Zhang Xian moved a pile of broken bricks to build some kind of building.

Tian Tian helped move bricks, and his clothes were dirty.

It's so hard to be a good person, and you have to dirty my clothes, but I've always been out of the country without staining. For the certificate, I also fought hard.

Looking at Zhang Xian's mud that combines soil and water, Tian Tian suddenly seems to see the most beautiful artwork - liquid hydrogen is not so beautiful, right?

Why does it feel so beautiful and beautiful? I think about it, when I was a child, I used to play with clay, and I loved to play very much, and my parents never gave up on scolding me.

She used a shovel to bring mud to Zhang Xian, remembering a mechanical formula when she was in middle school. Just think about it while working: where is the fulcrum, which is the power arm, and which is the resistance arm - the handle that should be held in the right hand is the fulcrum, the left hand is the power arm, and the shovel head is the resistance arm.

It turns out that physics knowledge is so interesting, but I hate that I don't like homework when I go to school.

Look at Zhang Xian's building has taken shape.

"Are you building a nest in the ground? You're going to start raising chickens, right?"

"It's not. ”

Zhang Xian put two large sleeves made of broken trouser legs and put them on the two square holes reserved for the building.

"Kid, can you use this to pick up the fungus?" the old lady asked.

"Yes, it's a vaccination box. Zhang Xian said.

"Isn't this a pool?" asked Tian Tian.

"The vaccination kit is very expensive, not as low as the cost of mine. Zhang Xian replied. "Of course, saving money is saving money, and I have to work on my knees. ”

"Hey, you said it earlier, I'll pay for you to buy a high-end one!"

"I'm sorry to ask for your money. ”

"It's okay, support private entrepreneurs. When your company goes public, just give me some shares. ”

"I can start a company. ”

"No problem, look at your smart and willful, hard-working spirit, it's no wonder if you don't succeed!"

"Well, I'll ask you to be the chairman of the board of directors when the time comes. ”

"Okay, that's a deal. ”
