Fable: any language that comes from fiction and has other sustenance, whether it's animal talk, bizarre story or dialogue between distant historical figures, belongs to "fable";
Repetition: Any repetition of the conversation or speech of the sages or ancients-that is, quotation or excerpt-belongs to the category of "repetition". As for whether these sages and ancients said these words, there is no way to verify them. Usually, Zhuangzi used these ancient people to express his views in order to increase the persuasiveness and authority of his words.
Nonsense: it is a language that is written fluently, read fluently and gives people a romantic aesthetic feeling.
