Zhuangzi is a famous Taoist figure, and his imagination is extremely rich. Until now, there are still some things about his imagination: I don't know whether Zhuangzi dreamed of butterflies or butterflies dreamed of Zheng Zhuang. He pursued nihilism, and his ideological realm reached a certain height, even an incomprehensible height. When his wife died and everyone was sad about her direction, he sang with gongs and drums, not because he didn't miss her. How can he have such a high imagination has something to do with his talent, his accepted ideas and his historical environment, which can't be explained clearly in one or two sentences.
