Green leather cars are magic to me.

When I was a child, my uncle participated in the construction of the third line, and Guiyang Railway Station was an important transit point. In the early years, many transistors and chips were developed in big caves in Guizhou. An old man who participated in the research and development of the first industrial computer in China told me: When you are tired, just lie down for a while, wake up and continue working, and you don't know whether it is dark or bright outside. The word "Spring Festival travel rush fever" first appeared in People's Daily 1980. Since the reform and opening up, with the relaxation of population mobility restrictions, more and more people choose to leave their hometowns to work and study. During the Spring Festival, many people gathered to go home, which formed a "rare population flow in the world" in the Spring Festival travel rush craze.

1990, my first year in Nanjing was in Pudong New Area, and later I will be Nanjing University of Integrated Circuits. Zhu Ziqing's prose "The Back" tells the story that happened in pukou railway station. I also learned to feel Pukou's slow life with Sanmao carrying steamed bread. Many farmers take chickens and ducks to the market by train.

Legend: pukou railway station in Zhu Ziqing's works.

199 1 Returning to Changsha from Nanjing, I began my "adventure journey" year after year. I have been on a steam train with smoke and gas, an internal combustion engine train burning diesel, and an electrified high-speed rail extending in all directions today.

After the arrival of the 20 10 high-speed rail era, the busyness in Spring Festival travel rush has been alleviated more and more, and it is hard to imagine the tense atmosphere that existed before 10.

Rail transit is a major driving force of economy, everywhere. Transmission lines, communication networks and cloud computing are also similar infrastructures, which have made great contributions to the global anti-epidemic.
