During the Qing Dynasty, there was a wealthy businessman who opened a pawn shop in Dong’an Town, Wujin area. One night, dozens of robbers came, robbed the pawn shop with knives, and injured two clerks. After the incident, the county magistrate strictly supervised the arrests and arrested the main culprit as soon as possible, but the culprit was not found for a long time. Someone recommended a scholar in Xixiang who was very good at using magic to catch fugitives.
