What are the jokes in The Romance of the Three Kingdoms that are not easy to find?

The most famous joke, of course, is that Guan Yu married a woman. Master Guan was also a vassal when he was guarding Jingzhou. Sun Quan wants to marry Guan Yu. So he sent Zhuge Liang's younger brother Zhu Gejin as an envoy to Jingzhou to find relatives and friends for his son. Guan Yu listened and said, well, both Sun and Liu are married to their in-laws, and they are also * * * resistant to Cao Cao. It's beautiful. So Guan Yu's clear voice replied, "My daughter Yan Yan is worthy." This means that my daughter Yan Yan can match Sun Quan's son. Therefore, Mr. Guan is a native of Shaanxi and has lived in the south for a long time. Their accents are completely different. Zhu Gejin listened: "How can a tiger girl match a dog!" This is too much. Jin Ge thought, if you don't agree, forget it. Why are you insulting people like this? I wanted to question Guan Yu, but I was blinded by Guan Yu's majesty and dared not ask. So he turned and left. Guan Yu is a good-looking man. When he turns around inexplicably, can he catch up with Zhu Gejin? Well, let's go. So the two families forged a hatred.
