High-Speed Rail Diary

The high-speed train is very fast, traveling rapidly on the Beijing-Guangzhou line that runs through the north and south. This is also the line of my youth. In a blink of an eye, time flies by. I want to catch something but it seems like I haven't caught anything. I looked up at the sky and thought about it without thinking. People always play different roles in different people's worlds. Maybe it is a star that always shines, or maybe it is a meteor that disappears in a blink of an eye... And what exactly are you to me?
