The Zhuangzi consists of a large collection of anecdotes, allegories, parables, and fables, which are often humorous or irreverent in nature. Its main themes are of spontaneity in action and of freedom from the human world and its conventions. The fables and anecdotes in the text attempt to illustrate the falseness of human distinctions between good and bad, large and small, life and death, and human and nature. While other ancient Chinese philosophers focused on moral and personal duty, Zhuangzi promoted carefree wandering and becoming one with "the Way" by following nature.
