This is what people are used to calling American humor. America is a mixed nation, and people of all colors gather together. Besides, English is a kind of phonography, which forms a unique humor in the process of communication. People call this kind of humor American humor, which is also called advanced literal humor.
But I personally think that humor has its own cultural accomplishment, a specific object and a specific place. Under the unique culture of China, a high level of literary humor is bound to be produced.
