I found booking train tickets with Travel China Guide a great experience.
I found booking train tickets with Travel China Guide a very easy process online. When I arrived at Chengdu Train Station to collect the tickets and could not find anyone that spoke English, I contacted Sunny Zhang (from Travel China Guide) and they were able to speak with the Ticket Office staff to allow me to get the pre-purchased tickets. Also when my air travel itinerary changed (before leaving Australia), I needed to change my train travel itinerary. I contacted the Travel China Office and Sunny was able to change my tickets and processed a refund, which I received within a few days back in my account. Overall I cannot speak highly of the great customer service I received from Travel China Guide, and particularly by Sunny Zhang. I feel she demonstrated a customer service which was well above my expectation. My wife and I were very pleased with her friendly help and assistance.
