I saw it too a couple of years ago. I wish at the time I was more aware of what I was seeing, our guide new English, but she was still difficult to understand.

BTW, the religious history surrounding Qin Shi Huang (who was a horrible tyrant) is very interesting as well.
Hummmm... I wonder why?
Maybe... she knew too much...
