I came across this NY Times article and video on Grand Central Station in NYC.

Does this article and video apply to the train stations of China in Beijing and Shanghai (you will likely experience one of them)?

Well, in my view, maybe the part about feeling ‘vigorous’ and ‘hypnotic’ from a people watching standpoint.

But any ‘ballet’ comparison? In China?

Uh, I don’t think so.  My experience has been that it’s often a free-for-all with massive numbers of bodies trying to get out of the train station with their life and luggage intact, including me.
