These trains are decorated as a "golden library": doors decorated with antique wooden doors are opened, and the walls on both sides seem to stand neatly with books. The ceiling is decorated with beautifully carved wooden boards, filled with vast starry sky, and the ground is also decorated with neatly arranged wooden floors.
A passenger got on the train decorated like a library and was very surprised. He told reporters: "This environment is quite good, with the feeling of a library and an atmosphere of learning. The subway I used to take was not decorated. This is at least an idea. "
The library-like train feels good and reveals a cultural atmosphere.
