Yim ji kau Trilha sonora (1987)

Fleur is the blue angel in one of Hong Kong's "flower houses" - bordellos and night clubs of the 1930s. A detached and beautiful performer, she falls in love with Twelfth Master Chan, heir to a chain of pharmacies. They agree to a suicide pact. 50 years later, in modern Hong Kong, Fleur's ghost appears in Yuen's newspaper office, wanting to place an ad to find Chan, who never arrived in the afterlife. Yuen, and his equally bewildered girlfriend, An Chor, are captivated by Fleur and her story.
