The full text of Master Zhuangzi is divided into three parts. The first part is the general outline of the whole article, pointing out that the most important thing in keeping in good health is to "interpret the classics along the edge", that is, to adhere to the virtual Tao in things and conform to the changes and development of nature; The second part takes a kitchen worker's decomposition of a cow's body as a metaphor for people's health preservation, explaining that life and life should be "nature-oriented" and "sky-oriented", and only by taking empty space can we be "comfortable" and avoid the entanglement of right and wrong and contradictions; The rest is the third part, which further explains the attitude of "obeying fate, conforming to nature and being safe and smooth".
