Xi'an Metro

About a month ago the Xi'an Metro opened!  So far only the north / south line is open but it's convenient for me when I'm at Chinese class and need to go inside the wall to the center of the city.  It was weird riding a subway here because I'm used to the crowded / old buses.  It feels like a real city now. 

Here's a video I took - it's actually less crowded then the buses.  I mostly took this video for the awesome guy with the earrings and glasses in front of me.
