How long should I stay in each of these places in China?

First off, yes I’ve tried posting on Chinese/China travel subreddits but no one really responds, so I’m trying here.

I 19F am planning my 2nd trip to China. I went to BJ, SH, Suzhou+Huangshan in April. The trip was far too short (2 weeks), so I want to go back for longer, check out new places, and try to find somewhere suitable as I plan to move there after uni (Likely either Chengdu or Beijing). I’ve got a rough idea of where to go/how long, but I’m open to suggestions.

天 = Days | EXCLUDING travel days

Beijing (5天) —》Chengdu (9天） —》 Chongqing （4天） —》 Zhangjiajie? (2天） or Jiangxi (idk which part yet) (3天） —》 Taipei （4天） ——————————————————————————————————————— As a traveller, I’m really down to try anything, but I have some main components I’m looking for -

Good hiking spots (Huangshan is unbeatable)

Opera, especially Sichuan Opera

Obvious essential famous spots (duh) (Already went to Great Wall+Forbidden City)

Eccentric little shopping area (Ex. Tianzifang in SH, NOT big name brand streets like Nanjing Road)

And maybe the most important, live houses + diy music/art scenes. I’m very interested in exploring the more alternative music scene in China and hear Beijing+Chengdu are my best bets. But I also get conflicting opinions.
