Gui yan (1974)

Plot:
Director Kuei Chih-Hung brings his vicious touch to a violent,
sexy story with one clear moral: never accept contact lenses from a psycho ghost. Poor Chen Szu-Chia does just that, and pays for it with her body and the gruesome death of her friends.

Overview:
International gore hounds agree: nobody makes horror
films like the Shaw Brothers Studio. Kuei Chih-Hung, who had already
made his name by directing such shameless thrillers as “The Bamboo House Of Dolls”, here brings his vicious touch to a violent, sexy story with one clear moral: never accept contact lenses from a psycho ghost. Poor Chen Szu-Chia does just that, and pays for it with her body (in every sense of
the word) and the gruesome death of her friends.
