Train pass in China

Hello,
I am visiting China for 5 weeks. Is it possible to book some sort of all encompassing train pass? Similar to the Japan rail pass or Euro pass? Or do I need to buy individual tickets?
I plan to visit Qingdao, Shanghai, Beijing, Xi'an, Chengdu, Kunming, Guangzhou, Hong Kong, Guilin, and Haikou. Possibly Tibet if I have time.
