Qingshan Experimental Primary School Office.

Jin Doudou stood in front of the head teacher Shi Li with his head down.

Looking at a mosquito killer in her hand, Shi Li's tone was stern.

"Jin Doudou, what's going on with you lately? I'm always late for class, I usually either forget to bring a red scarf or forget to wear a school uniform, and now I start to openly sell things in school, are you here to go to school or to sell things?"

"Teacher, I'm sorry, I'm just ...... I just thought it was very easy to use, so I introduced it to my classmates. ”

"Did you introduce you like that? Even the money was collected?"

"I ......"

"Don't talk about it, let your parents come to school tomorrow. ”

Back in class, Jin Doudou's tears kept rolling in her eyes.

No matter how much the teacher criticizes herself, she can accept it, but what she is most afraid of is the teacher meeting the parents.

Jin Doudou is an unfortunate child, and even more unfortunate family.

When she was still very young, her father divorced her mother, and her mother didn't know where she went, so she lived with her father. Later, my father remarried and married a woman with a child, although she said that she was a stepmother, but that woman was very good to Jin Doudou, and for a while, Jin Doudou felt that life was very happy.

But then my father had a mining accident when he went down to dig coal, and although his life was saved, he became disabled and could not take care of himself.

The stepmother was unable to bear the burden of the family, so she quietly left the house in the middle of the night with the child.

Jin Doudou doesn't blame her stepmother, she doesn't have the ability to bear the burden of this family.

Fortunately, with the help of the community, Jin Doudou's father Jin Lei was given a subsistence allowance, and he finally had a stable income. Usually after school, Jin Doudou goes to pick up some waste products to sell, and sometimes goes to the construction site to pick up some construction waste to sell.

"What should I do?"

Thinking of his disabled father, who had been lying in bed, Jin Doudou's tears crackled down.

Suddenly, a figure came into her mind.....

Aoyama City in May has entered the summer season ahead of schedule these days.

The persistent heat turned the entire city into a fire cage at two o'clock in the afternoon.

The poplars on both sides of the street are listless, and the willows are quietly hiding their new shoots in the branches.

Outside a remote convenience store on Castle Peak Street.

Chen Dong was constantly carrying things from a truck into the store.

After a while, sweat soaked the back of his clothes.

"Mom, you come to the store and rest, I'll just move these by myself. ”

Seeing her mother Yu Xiuqin follow her to move things, Chen Dong pushed her into the store.

But every time he pushed Yu Xiuqin into the store, she always ran out to carry things again.

In the end, Chen Dong really had no choice but to move a few more pieces at a time.

The two of them finally moved everything to the convenience store, and they were both sweating profusely.

"Xiuqin, Dongzi, quickly wipe your sweat and drink saliva, blame me for being too useless. ”

Looking at the appearance of the mother and son, Chen Binglu kept blaming himself.

Chen Dong hurriedly said: "Dad, you are not allowed to say this in the future, I still expect you to shout and shout more when you set up a stall tonight." ”

"Yes, Lao Chen, when you were young, you were a militia company commander, I remember that you didn't have to make drafts when you spoke, and you couldn't drop the chain when you set up a stall at night, right?"

Hearing her son say this, Yu Xiuqin also said next to her.

"Don't worry, your legs and feet are not good, and your mouth is okay, and you can watch me when you set up a stall at night. ”

Hearing the two of them say this, Chen Binglu's heart felt a little better, and he swore a promise.

"By the way, Dongzi, what are these to you? Tell me quickly, I'm ready to prepare. ”

Chen Dong took one item from the shelf and opened it.

said: "This is the latest black technology product, portable mini air conditioner. ”

"Air conditioning?"

"Black technology?"

"Son, what is black technology?"

Chen Binglu asked with a blanket face.

"Dad, I'll give you a good talk, this black technology is also the meaning of special high-tech, and this air conditioner actually uses ......."

Chen Dong told Guo Yue what he said to his father again.

After listening to this, Chen Binglu said: "Then the selling point of this product is high-tech?"

"Dad is very powerful, and he asks very professionally. If you want to talk about the selling point, I think it's not just black technology, first of all, it can quickly cool down, and it can also purify the air, and now the air quality in the city is not good, so purifying the air is also a selling point. ”

What made Chen Dong cry and laugh was that Chen Binglu actually took a small notebook from somewhere and carefully memorized what Chen Dong said.

"It's not cheap, is it?"

"Hey, Mom, Dad, guess what, how much is this thing worth?"

Yu Xiuqin guessed first: "500 yuan?"

Chen Binglu shook his head. "Xiuqin, you have been in elementary school for a few years, didn't Dongzi say it just now, this is a high-tech product, it can also purify the air, and it can't be reduced by 1,000 yuan. ”

Chen Dong held back his laughter.

"Dad, Mom, you all guessed wrong, this is only 268, what do you guess my cost price is?"

“168！”

The two of them stared at each other with big eyes.

168！

The cost was low enough, and they never thought it would be so cheap.

Sunset.

The city of Aoyama City is finally a little cool.

This cool air makes people feel very comfortable.

The dreary streets began to become lively, and people came out of their homes in twos and threes to enjoy the rare coolness.

Castle Peak Street is an old city street, there are no particularly tall buildings on both sides of the street, and there are no large shopping malls, and more old residents live here.

While strolling through the night market, chatting about the shortcomings of parents has become a habit of life for residents of Castle Peak Street.

As soon as Chen Dong's family of three set up the stall, Uncle De walked over with a few old neighbors.

"Dongzi, your mosquito killer is so easy to use, I finally had a good night's sleep last night. ”

Before the person arrives, the sound arrives first.

When Uncle De and the others approached the stall, they found a big sign next to the stall.

【Mini Air Conditioner Sale Price】

"Hey, Dongzi, the mosquito killer is no longer for sale?"

"Uncle De, I don't sell mosquito killers today, I have another high-tech product, a mini air conditioner, an air conditioner that can be carried around. ”

Seeing that his son and Uncle De were talking happily, Chen Binglu and Yu Xiuqin had smiles on their faces.

"Who are these two?"

Seeing the two people, Uncle De looked at Chen Dong.

"Uncle De, this is my dad, this is my mom. ”

"It turned out to be Brother Chen and his younger siblings, you have a good son, if he didn't have a girlfriend, I really want to introduce my niece to him, haha. ”

A few people chatted for a while, and many people came to Chen Dong's booth one after another.

Chen Dong smiled, naturally it was the matching function of the stall system that played a role.

"Come and see, come and see, the latest black technology products are not only mobile air conditioners, but also purifiers of nature. ”

"Fresh and visible, fresher air. ”

Without waiting for Chen Dong to speak, Chen Binglu opened his voice and shouted........
