"Hello! Lao mu, it's nearly 20 years since I graduated from primary school. When everyone else has arrived, I'm sorry for you. By the way, we'll meet you at the airport... " Looking at the newly invented electronic equipment, I thought that the company had given me a few days off, so I took a private plane and flew from the United States to my hometown.
Just after getting off the plane, the old students came by a maglev bus. The monitor introduced me: "this one is Dr. Li, that one is boss Chen, and the middle one is scientist Zhu..." I looked up and saw that my classmates had changed so much that I couldn't recognize them. It was dark, driving on the road, my eyes were dazzled by the shining grass. The monitor said: "this is a kind of genetically modified grass. Only when the grass is injected with the gene of firefly, it will light up. Because of this kind of grass, the street lamps in many places are not needed now!"
Midway through, we got off at our alma mater to have a rest. There was only a white light, and then a 3D man appeared in the air. It said: "welcome 20 students back to school to visit." Suddenly the turntable rolled under our feet, and within seconds we were outside a classroom. Through the glass, I saw a teacher turn on a switch, and the classroom turned into "Grassland" in an instant. I see. This class must be science. Then I saw the switch of music class, Chinese class and art class. I was stunned. It was really different from our previous classroom.
After leaving my alma mater, I came to Chen classmate's company again. I saw that there was no one in the whole assembly line, only one machine was operating the computer. Production of a computer, from raw materials to packaging, as long as 180 seconds. Chen said: "this kind of machine is very easy to use. After I use it, I not only save cost, but also fast and good. I'm going to buy some more! "
Next, I visited Dr. Li's office and Dr. Zhu's Laboratory When I visited Changsha, I couldn't help feeling: "Changsha has changed so much and so beautiful!"
