The Story of Jang-hwa and Heung-ryeon.

Jang-hwa and Hong-ryeon, the daughters of Bae the official governor, die of their stepmother's unfair maltreatment. Jang-hwa's ghost appears in front of a district judge every night begging for clarification of their deaths. The district judge lets the stepmother confess the cause of Jang-hwa's death, and then punishes her. It clears all enmity.
