Song at Midnight (1985)

Sun Xiaoou and Green Butterfly are actors from Angel Theatre Company. Rumors of being haunted were circulating in the theater troupe, and the two discovered that the "ghost" among the other people was actually Li Xiaoxia, the daughter of local tycoon Li Xianchen. Li Xiaoxia is now crazy, and the reason can be traced back to a love story between her and the once famous actress Song Danping. Li Xiaoxia and Song Danping's relationship was strongly opposed by Li Xiaoxia's family, simply because Song Danping was an actor with a low status. In order to disrupt this marriage, Li Xianchen secretly found someone to pour alkaline water on Song Danping, causing her to disfigure. In despair, Song Danping threw herself into the river and Li Xiaoxia went crazy. In fact, Song Danping did not die, but instead secretly accompanied Li Xiaoxia under cover. Song Danping hoped that Sun Xiaoou could help her cure Li Xiaoxia's madness.
