How to save money from Nanjing to Lhasa

If you buy a plane ticket, come to Lhasa airport from Shanghai, or from Nanjing-Chongqing-Lhasa and Nanjing-Chengdu-Lhasa, but I tell you, the plane ticket is more expensive at this time of tourist season. . . . When I was at school, I used to think that air tickets in summer were twice as expensive as those in winter!

Then ~ just take the train. There are 650 to 800 hard sleepers and more than 200 hard seats, but I think it is better to take a hard sleeper for about 48 hours by train.
