Pan Jinlian
"Jin Ping Mei" is framed as a spin-off from "Water Margin". The beginning chapter is based on an episode in which "Tiger Slayer" Wu Song avenges the murder of his older brother by brutally killing his brother's former wife and murderer, Pan Jinlian. The story, ostensibly set during the years 1111–1127 (during the Northern Song dynasty), centers on Ximen Qing (西門慶), a corrupt social climber and lustful merchant who is wealthy enough to marry six wives and concubines.
