One day in October 2023, Beijing time, at Shenzhen Security Airport, a boy in a green coat walked down from a plane flying from the United States to Shenzhen, he was me, Chen Haofeng in 2023. After getting off the plane, I looked around, and ah, Shenzhen has changed a lot! Everywhere is full of green trees, high-rise buildings are rising from the ground, and the Diwang Mansion in the past is now almost invisible.

When I got out of the airport, I saw that taxis on the street had become very scarce, but private cars were increasing. Then I passed a winged Mercedes Benz, and it drove on the road, and I saw that the speed was getting faster and faster, and all of a sudden, it flew like a cloud.

Walking on the road, I saw an old man walking, suddenly, he took out a piece of paper from his pocket and threw it on the ground, I was about to pick it up, but as soon as I walked over, the paper was gone, I felt very puzzled, at this time, the old man turned around, looked me up and down, and then asked, "You just came back from abroad, right?" I nodded hurriedly, and he continued

Over the years, Shenzhen has changed a lot! If the garbage is thrown on the road, the ground controller will automatically dispose of the garbage. When I heard that, it dawned on me.

Arrive at the hotel and drop off your luggage. At this time, I felt very tired, so I sat down on the sofa, and suddenly I saw that the walls became transparent, and there was a green shade outside, and I could see the vast sea. I feel much better.

It turns out that every room in this hotel has automatic sensors, and whenever you feel tired or uncomfortable, the sensors will automatically change the environment. When I opened the fridge, there was nothing in it, so I had to go to the supermarket to buy it.

In the supermarket, which is full of many items, I lift the shopping basket and it says: you just put the purchased items in the basket and it will disappear immediately, at which point it has automatically arrived where you live. I picked up a bag of cookies and put them in, and suddenly it was gone.

After shopping for the items you need, go back to the hotel, open the door and see that everything is on the ground, and there is a payment machine next to it, you just have to put the money in it, it will automatically give change, and the payment machine will disappear automatically.

At this moment, I felt a great pain in my head, and by this time, I was back in the present, and I opened my eyes, and I looked, oh, it was just a dream.

But I firmly believe that in the near future, our Shenzhen will definitely become very advanced!

Today is Sunday, my mother went grocery shopping, my father went to work, I was the only one at home, I was lonely and I wanted to find something to play, I rummaged through the glove box in my house, but two black insects came out, ah, it was "Xiaoqiang" - cockroaches, usually only saw the fissure mother to kill cockroaches, but I didn't, this time, my mother was not there, what should I do?

In desperation, I mustered up the courage to show my skills and destroy the cockroaches. So, I'm going to use my iron feet to come to Silverbridge to deal with these hateful bugs.

With a snap, my foot slammed on the cockroach. Hey, the cockroaches are quite smart, and when they know that I am going to trample them to death, they cleverly dodge to the side, and they are glad that they were spared, which annoys me now, and I think: lowly "little strong", I want to break you to pieces.

Not to be outdone, I hit hard again and missed, but I still kept one hand and used the other to deal with an arrogant bedbug. There was only one left, and now, that cockroach was already afraid of me, so it wanted to back down. So, he ran down the stairs desperately, and I didn't want to give up the prey I had in my hand, and ran that way, after all, I was bigger than it, so I ran faster than it, and it hid in the corner of the stairs, not wanting to die.

The two of us immediately became in a confrontation situation. Or I broke the silence, I stepped on it, it jumped down the next step, I didn't step on it, at this time, I wanted to repeat the old trick, one foot down, empty, another foot, I thought that the "Xiaoqiang" that had annoyed me for a long time died, as a result, it was still half dead, I kicked again, and ended its miserable life.

This is a human-insect battle that is beyond history, and in the end it is won by a human, which is really interesting!

My mother came back, and I told my mother about it, and even my mother, who usually doesn't smile, laughed, and this funny thing made me unforgettable for the rest of my life.
