It is to use the conditions of homophones or near homophones of Chinese characters to replace the original words with homophones or near homophones, resulting in poetry.

For example:

(1) The woman's original surname, born with a big belly, married a lazy man to eat sauerkraut, and married a diligent man to eat meat and fish.

Guess a vessel (answer: vegetable pot)

(2) Uncle Xing had a drink and said, "... The land said," This wall is not strong. " The gods will say, "Look." At first glance, this land is really a good wall. How could there be a crash? Touching his hand, he said,' I thought it was a real wall, but I didn't know it was a fake wall! "Hearing this, the people burst out laughing. Jia Qiang

I couldn't help laughing and said, "Silly uncle! Hello! I didn't scold you. Why did you scold me? Here, punish it with big glass! " (Cao Xueqin's Dream of Red Mansions)

The earliest homophonic implication that we can research now can be found in Zhuangzi's article about 2,500 years ago. In Zhuangzi? In "The Lord of Health", I used a knife to solve the problem of cattle according to the reason. A knife has been used for nineteen years, and it is still as good as new. "Nineteen" means "long" and means everlasting.
