Per the videographer:
Once again I had a week off a work, so of course I took a little trip. A small group of us went to Xi'An. It started off with a 21 hour train trip on a hard seater that was completely packed with people in the aisle and everywhere, but it turned into a really really fun time once I got to Xi'An. Here is a glimpse of the fun we had.
