Zhuang Zhou once had¹ a dream². He dreamt of himself³ turning⁴ into a butterfly, flying in the air, feeling⁵ like he was real⁶ capriccioso（活泼自由的） butterfly. In his dream he was amused⁷ and exhilarated（振奋的） without noticing⁸ that this butterfly was only something in his dream. After a while⁹, he woke¹⁰ up and found¹¹ that he was still himself, not a butterfly. He felt surprised¹² and couldn't tell whether¹³ it was he turned into a butterfly in his dream or a butterfly turned into him. 庄周做了一个梦，梦见自己变成了一只蝴蝶，飘飘而飞，俨然自己就是一只生动活泼的真蝴蝶。 他梦中觉得非常有趣，非常得意，不知道蝴蝶是庄周梦中变成的。过了一会儿，他一梦醒来，见自己仍是庄周，又不是蝴蝶，觉得十分惊奇，他实在不明白是自己在梦中变成了蝴蝶呢?还是蝴蝶在梦中变成了自己。
