I'll second the rec for Tai Sui and also throw in a rec for The Langya List (the novel Nirvana in Fire was based on) if you haven't read it. The novel is gen -- I gather the drama added more of a romantic element with Nihuang but that's not there in the book.

I think these are the only two gen cnovels I've read -- no, wait. We Live in Nanjing (a sf novel that came up in discussions of last year's hugo nominations debacle) is gen, and it was a fun story, communicating with someone in the future via ham radio to prevent an apocalypse. But there's only an mtl translation for now.
