Asian Brass

Li Ping, a female high school teacher, is a screw in a system of teaching and heavy discipline. Her daily rift with "bad students" make her feel ridiculous and desolate. She has regular trysts with a married male teacher in an old house that is about to be demolished, but at some point she begins to see her grandfather, who has been dead for years.
