Abstract: Zhuangzi replaces skill with fantastic skill which conforms to Dao (meaning that everything in the world exists and develops in a natural way)，thus fantastic skill，seemingly a kind of skill，has no definitive property of skill in essence.While skill has certain purpose，fantastic skill is to do things freely in a natural way；skill is a kind of creation which damages the original nature，but fantastic skill remains it.Fantastic skill is not realistic skill or its analogy，but the naturalized or idealized imagination，being mysterious.The logic result of fantastic skill is to cancel and deny realistic skill，hence the paradoxical sayings of“painting without painting” and “fishing without fish”.After later theoretical transformation，the unity of fantastic skill and realistic skill is achieved，and then appears the idea of “rule without rule” in artistic creation.

Key words: Zhuangzi；fantastic skill；skill, paradox；letting things take their own natural course
