I've been trying to plan a trip to China with my roommate in September and so far we figured out Beijing, Xian, and Chengdu with a visit to the Giant Buddha (Thanks Tripadvisor/Virtual Tourist! :D.) Anyway.....we're still trying to figure out what to do after Chengdu. Train to Lhasa? Yangtze River cruise? Any suggestions would be very helpful. We basically have the 15/16 - 21st to play with. We're trying to leave from Shanghai or Hong Kong back to the states. Suggestions welcome!
