Railway culture, Yunnan train has a long history, rich variety, the library text, pictures and videos are very detailed, calm down to slowly enjoy, quite a pleasure. There are many real antiques, trains and rails are silent, but they can tell history quietly and tell a small story. I like Michelin best. It's a comfortable and luxurious business car with tires. It's white. It's very gentle and elegant. The track of narrow-gauge trains is really narrow, which explains why Yunnan is so weird that trains do not pass through China and abroad.
