Hongcun ( 宏村 ) is a small, old village in Anhui province - and it's location of the opening scenes of Crouching Tiger, Hidden Dragon. This fact made Hongcun one of the most frequently visited tourist attractions in China. I saw images from before the movie, from the '90s, and there were absolutely no sign of the level of decoration anywhere, let alone the hurds of humans cross the bridge the same direction Li Mu Bai did.
Hongcun has a very unique water - and plumbing system. The South Lake in this photo it's essentially the storage tank of city-wide hydrophonics with biological cleaning.
