The Yu brothers are experts in Feng Shui, and no one shows it to them.
In the forty-fifth chapter, two brothers from the Yu family looked at the feng shui of one of their ancestral graves. The owner brought a few pieces of soil in a red cloth bag. Yu Yin took out a piece of soil and put it in front of him and put his head on it. He tilted his head to the right and looked at it for a while, tilted his head to the left and looked at it for a while. He picked off a piece of soil with his fingers, put it in his mouth, and chewed it with his mouth tilted.
In this passage, the author vividly and slightly exaggeratedly describes various ridiculous and despicable actions of the two brothers of the Yu family, and the language is extremely ironic.
