Ximen Qing is a wealthy pharmacy proprietor in Yanggu County whose money and official connections make him one of the most powerful private men in the early chapters of Water Margin. His encounter with Pan Jinlian begins as desire, but Wang Po turns it into an organized affair by providing a room, excuses, and secrecy. Ximen Qing’s danger does not come from heroic combat. It comes from a social position that lets appetite recruit servants, brokers, and minor officials.
When Wu Dalang discovers the lovers, Ximen Qing kicks him badly enough to leave him confined to bed. Pan Jinlian fears that Wu Song will return and demand justice, so the pair follow Wang Po’s plan and poison the injured husband. They hurry the cremation and use Ximen Qing’s influence to smother suspicious evidence. The murder exposes the center of his character: pleasure is protected by money, and violence becomes acceptable once an inconvenient poor man threatens disclosure.
Wu Song’s return destroys that protection. After the local magistrate refuses to act on uncertain testimony, Wu Song gathers witnesses, forces a confession from Pan Jinlian, and pursues Ximen Qing to complete the vengeance. In the best-known sequence they fight at the Lion Restaurant; Ximen Qing resists but cannot withstand the tiger-slayer and is killed. His severed head joins Pan Jinlian’s at Wu Dalang’s altar. Ximen Qing is therefore more than an adulterous stock figure: he embodies the alliance of wealth, lust, and local corruption that private justice violently overturns.
