There are a couple xianxia novels. Reverend Insanity (incomplete banned by the ccp but has some of the best word building and intelligent writting), Lord of Mysteries (more western fantasy lovecraftian mystery) and Forty Millennium of Cultivation (has 40k elements in it). Non fiction isn’t really popular probably because anything non fiction in China that has anything to do with history is at risk due to censors and people in the west aren’t really interested in reading ccp bootlicking.
