I took a ride on the Beijing subway last night. It pretty much felt the same as the subway in NY including tons of asian people! The train was crowded for this ride, but when we rode again a little later it was packed to the point that you could not move an inch. It was impossible to take video on that ride. I was told they do have some pushers like in Japan, but not too many. Unfortunately I didn't get to see any in action.
Youtube really butchers the quality of the video. The original I have it much better quality. It's not horrible, but if you view in the smaller size it's a little better.
