Ghost Ballroom

Ghost Ballroom (1989) is a action, comedy, horror directed by Wilson Tong Wai-Shing rated 6.3/10.

A club hostess is murdered by her gangster boyfriend and her ghost comes back for revenge. Her two hostess housemates are much more upset by her return than her death (which didn't seem to bother them much at all), and their boyfriends are kind of freaked too, but when they're not gambling they are persuaded to help the ghost take revenge.
