Brother Yun couldn't get money from Ximen Qing, so he tried to find Wu Dalang. I also told him a little about Pan Jinlian's affair outside. There is a big gap between Wu Dalang and Pan Jinlian. Although the relationship between husband and wife is not good, it is like finding out whether Pan Jinlian is really fooling around outside. For this reason, please invite Brother Yun to eat steamed bread with wine and meat, and give him money to make things clear. Also let Wu Dalang get a chance to catch him, but also because of the suggestion of Yun, Wu Dalang discovered the affair between Pan Jinlian and Ximen Qing.
From here, there seems to be no friendship between Yun Ge and Wu Dalang. And Ximen Qing are birds of a feather. Ximen Qing is a local strongman, and Brother Yun is Ximen Qing's younger brother. In Water Margin, Brother Yun once threatened Ximen Qing's big momma. If he didn't give him some benefits, he would tell Wu Dalang about Ximen Qing and Pan Jinlian, who sells baked wheat cakes. In fact, it was because Brother Yun exposed Pan Jinlian's adultery that Wu Dalang was killed by Ximen Qing to avenge his brother and kill Ximen Qing.
Generally speaking, Brother Yun is not a positive image. Although Ximen Qing is lascivious and powerful, he secretly commits adultery with Wu Dalang's wife, but he takes good care of Brother Yun and gives him more money to subsidize his family. From Brother Yun's point of view, Ximen Qing actually didn't do anything wrong. But because Yunge couldn't get the money, he deliberately revealed the affair between Pan Jinlian and Ximen Qing to Wu Dalang, which indirectly led to the death of Wu Dalang and Ximen Qing, and Song Wu was arrested. Brother Yun is not a good person.
