I don't think China has whole districts or areas dedicated to Bohemianism like in the west, but the scene is confined to venues and places scattered all over the place. You'll find intellectual types, artists and musicians in all major Chinese cities and most of them organise their own hangout sessions, usually in someone's home so you're not necessarily going to hear about it.

Bohemianism I don't know . But many Chinese girls like Bohemian style of dresses . they think it's fashionable .
