After learning the truth, the magistrate, in order to maintain the reputation of the family, designs a venomous scheme and, through the hand of Bi Lan, poisons to death the junior silversmith who has been cheated into the official residence to do silver ornaments. In order to avenge his son, the senior silversmith tampers with a self-made silver ornament and thereby kills Bi Lan, and then commits suicide.
