I'm going Harbin. I will take my flight from Kuala Lumpur to Tianjin by AirAsia X. What is the best and the cheapest transportation to Harbin. Should I go there through Beijing or directly from Tianjin?

How can I go to Beijing to Tianjin from Tianjin airport? Could anyone explain it? Thanks.

Could you provide me the list of train timetable and fare from Tianjin to Harbin & Harbin to Tianjin and Beijing to Harbin & Harbin to Beijing? Could you also provide me some info about hotels and transportation in Beijing, Tianjin and Harbin?
