Found China Xi’an Tour on line. Sophia very quick response email/chat. Very safe and confident to do transactions with booking. We booked private airport transfer, HuaShan and ShaoHuaShan private tours. Drivers is very on time pickup, and definitely very safe and professional drivers. Tour guide Noble spoke fluent English. They are very patient to waiting for us, during our tours. (We travel with group of nine with young kids and elderly person) I’m willing to recommend China Xi’an Tour to anyone need a private tour of Xi’an and airport transfer.
