In Yanggu, Wu made a living by selling pancakes while his wife stayed at home and managed domestic affairs.
[1] The adulterous pair were making love when Wu Dalang returned home and caught them in the act.
Then, Ximen Qing had Wu Dalang's body cremated, and he tried to bribe the neighbours and the coroner to keep the affair a secret.
Eventually, Wu Song managed to force a confession from Pan Jinlian and he killed her to avenge his brother.
In Water Margin, the older novel, Wu Song kills Ximen Qing in broad daylight and is exiled.
In Jin Ping Mei, however, Ximen Qing escapes and bribes the county magistrate to have Wu Song arrested and exiled.
