Therefore, Zhuangzi thinks that people should let nature take its course when they live in the world, in other words, they should pursue the authenticity of people, not man-made. Therefore, Zhuangzi advocated "doing nothing", getting rid of worldly troubles, and pursuing the unity of nature and man.
And "knowing a cow by skillful hands" can be said to be a reflection of Zhuangzi's health care thought. Ordinary chefs cut tendons and bones with a knife, which is easy to blunt and just too persistent; However, as a skilled worker, I know how to follow the texture of cattle, which is the principle of following nature.
So what is the principle of nature? We can give another example. As we all know, running water is the most natural. How does water usually flow? Flowing into cracks, not deliberately penetrating rocks. Therefore, it can also be said that Tao is subordinate and indisputable. Only by not arguing can we approach the Tao, and by doing nothing can we conform to the Tao. Those who have the Tao will not be hurt by foreign objects.
