Laozi Zhuangzi "integrates the works of Laozi and Zhuangzi, with Laozi compiled by Laodan and Zhuangzi compiled by Zhuangzi Zhou. Laozi explains the evolution of all things in the universe through the concept of "Dao", which states that "Dao gives birth to one, one, two, two, three, and three all things", and "Dao" is "the command of Fu Mo and always natural". Therefore, "Man follows the earth, the earth follows the heaven, the heaven follows the Tao, and the Tao follows nature". The "Dao" is an objective natural law, and at the same time, it has the eternal meaning of "independent and unchangeable, walking without danger".
Zhuangzi consists of 33 chapters, divided into three parts: "Inner Chapters", "Outer Chapters", and "Miscellaneous Chapters". It is generally believed that the seven chapters in the "Inner Chapters" were written by Zhuangzi, while the fifteen chapters in the "Outer Chapters" are believed to have been written by Zhuangzi's disciples, reflecting his true thoughts; The situation of the eleven chapters in the "Miscellaneous Chapters" is more complex and should have been written by the Zhuangzi school or later scholars. The most concentrated expression of Zhuangzi's philosophy in the inner chapters is "The Theory of Qi Wu", "Xiaoyao You", "The Great Grandmaster", etc.
