How to travel as fully as possible in China with 30 thousand yuan?

Shandong to Chongqing to Chengdu, Sichuan to Qinghai to Yunnan to Xinjiang to Tibet to Nepal are recommended. First of all, from Chongqing to Chengdu, the train usually takes two hours, which is very convenient and fast. Then after Chengdu, Qinghai, Yunnan and Xinjiang are three places. The point is that the Qinghai-Tibet Railway is so beautiful. If you have the chance, you must take this train. This 30,000 yuan tourism fund is still relatively abundant.
