We were in Xian in late September with Michael as our guide for Hua Shan and Terrra Cotta. He was very prompt in picking us up (in fact we were the ones always running a little late), provided us with good advice, and very flexible. We were stuck in a major traffic jam on the way back from Hua Shan and he maintained his good nature. His English is very good. We highly recommend him if you are ever in Xi'an.
