Painted Skin (1993)

Original title: 畫皮之陰陽法王

When an amorously inclined young man runs across an attractive young woman in need of his help, it's not difficult for him to rush to her aid while imagining himself in her arms. Though he's married, he retains a strong desire to bed any pretty woman in sight. To his shock, he discovers later that the pretty woman he fantasized about is a ghost.
