Leg cramps, ghosts of dreams

It should be 1987 old ghost story. Starring Leslie Cheung and Joey Wong. The story begins with a competition between two people, and then one of the men is injured and washes his wound by the stream, and then he is seduced and sucked by a female ghost. . . But heroes are scholars, not generals ... Look, this is a classic movie. It is a new classic that cannot be copied.
