This is the famous "mid-air temple" that is located south of Datong in Shanxi Province.
Tickets are a little expensive, but worth every RMB as this is an impressive structure.
You walk around on a one-way route, and a few places may be a little exposed for those who suffer vertigo.
Getting there can be a challenge as there can be very long traffic jams owing to the Shanxi coal trucks that clog the roads.
