Recently, at the Chengdu subway experience site, a group of people showed their self-made paper models of various subway vehicles in Chengdu.
According to the producer Lan Qiguang, he is still a student, because he loves the subway and cannot buy a model, so he came up with the idea of making a subway car model.
