Demi-Haunted(2002)

Wan Fei (Joey Yung) is a promising Chinese Opera singer who is secretly in love with Ho Fung (Nicholas Tse). She plans to sing for him from the stage, but, in a tragic accident, dies mid-song. Years later, Wan Fei's ghost returns, and finds that part of her spirit has been reincarnated in the form of Chor-bat (Eason Chan). Wan Fei still longs to sing her song for her lover, and, after much humorous confusion, her dream is fulfilled.
