What are the wonderful uses of homophones in life?

Homophones are a linguistic phenomenon in Chinese. In ancient times, some poets used homophones in their poems to exploit classes or bureaucrats, and used them to implicitly criticize their behavior and the bad atmosphere of contemporary society. Homophony may be of little use in modern society, after all, it has entered the high-tech era, the network is so developed, materialization is becoming more and more obvious, and these deep cultural connotations are gradually ignored. But it is also used in some titles and satires that expose social phenomena. That's probably it, but when it comes to magical use, it should be more than that. If you have the conditions, you can ask the Chinese teacher or some professors and experts in the Chinese department of the university. Students in the Chinese Department should also know something. You can ask them.
