If you like martial arts (specifically wuxia) there are a few books by Jin Yong that have been translated. I've read and can recommend both of the following (with The Book and the Sword being, by far, the better of the two.) The Book and the Sword Fox Volant of the Snowy Mountain Brothers by Yu Hua is also a highly critically acclaimed book. If you know a bit about the context (the Cultural Revolution) than you will probably enjoy it.

I guess Shanghai Baby (上海宝贝) was originally in Mandarin? Banned in China though, apparently!
