Erh-ke told Wu Sung the whole story of how P'an Chin-lien and Hsi-men Ch'ing had cuckolded Ta-lang and how Ta-lang had been injured by Hsi-men Ch'ing and eventually died. After Wu Sung heard all this, he hired someone to write a complaint and went to the county court to protest. The magistrate read the complaint, listened to Erh-ke's testimony, and then withdrew to consider the situation.
