1 month china

If I understand it right, I can travel right now as a german citizen for 30 days visout a visa through China. The idea came up a few days ago because im travelling through south east asia right now, so I could go there maybe in april or end of march. Now I made a few list of things I would like to do but I'm not sure how the route could look like. - Shanghai (I would like to start there bc a friend I met in Thailand lives there) - Peking + chinese wall - Xi An + Huashan mountain - Chongqing - Zhangjiajie nationalpark - Chengdu + Leshan - Lijiang

Is it too much or would you recommend to skip something or would you add something?
