Hello, I'm asking Zhuangzi. The theme of the fourth "Health Master" refers to the secular health culture, right? The theme of the fourth chapter of Zhuangzi Neipian is that the secular health culture is wrong. "Health Master" is the key to health. Zhuangzi believes that the way to keep fit is to conform to nature, forget your feelings and not be trapped by foreign things. It is embodied in following the right path of nature and taking it as the unchangeable law of conforming to things. Only in this way can we protect ourselves, preserve our nature, leave no worries for our parents and enjoy the rest of our lives. Zhuangzi is an open-minded person who is good at photography. He was 83 years old. His way of keeping in good health is mainly reflected in four aspects: selfishness, no desire, meticulousness and detachment.
