China Built a Giant Indoor Traditional City — It Even Has a Sky Train
Experience China’s incredible architectural feat: a massive traditional-style city built entirely indoors. Complete with temples, markets, courtyards, and even a suspended sky train, this city recreates the essence of ancient China inside a modern structure. A breathtaking blend of culture, innovation, and scale

 

I don't know if it's that way or not.
I've been to a couple of those giant malls and it's like being in a dream world. Extremely impressive and immaculately clean and orderly.

 

Hope to do this one on our next trip. Every train has a doctors clinic in case any passengers get altitude sickness. Also has extra oxygen supply for those not used to the thin air.
