Fuming with rage, Erh-ke ran to find Ta-lang and told him all about Hsi-men Ch'ing and P'an Chin-lien. Ta-lang said:" No wonder the woman goes to Wang P'o's house every day, and her face reddens when I come home. I have been suspecting that something is wrong. So, that's what she is doing!" Ta-lang and Erh-ke then agreed to catch the couple in the act the next day.
