Go around any public park at night in China and this is a scene you will most likely find.  It’s a form of leisure as well as exorcise for the elderly. You can’t see it in this video because it’s so dark, but there are about fifty or so people following the dance steps.  It’s a very traditional form of Chinese dancing, and juxtaposed with the techno music they play it makes for a pretty entertaining sight.  At one point, the music turned to a bunch of guys chanting “We don’t give a damn, we don’t give a fuck.”  I was the only one person in the audience who seemed to know what that meant.
