Let’s talk about breaking the casserole and asking how to use homophony.

It turns out to be "break the casserole and drive it to the end", which is pronounced as "wen" in the fourth tone and the same question. Since it sounds the same as "went", the word "went" was changed to "went". The cracks are the cracks on the casserole. If the casserole is broken, there will be cracks extending to the bottom of the casserole.

This allusion comes from Huang Tingjian's "Ode to Zhuoxuan" of the Song Dynasty. There is a sentence in it: "If you look for cleverness, you can't find it. Where does clumsiness come from? Breaking the sand basin and asking, the madman's eyes will be opened because of this, and he will be a snake." Painting is enough, not to mention putting a head on the head and a house on the bottom. After all, there is more for those who are skillful and less for those who are clumsy.”
