The first is "less people". Zhuangzi believes that private is the root of all diseases. If a person takes the word "private" as the first priority, haggle over every ounce, be swayed by considerations of gain and loss, and be restless all day long, it will inevitably lead to serious problems. He put forward the insights that "my life is infinite, but my knowledge is infinite" and "silence can make up for illness", that is to say, human life is limited, but knowledge is infinite. Let nature take its course, get rid of the heart of seeking fame, and the spirit will be relieved, so as to "keep in good health, preserve one's health, and spend one's life safely." Less privacy will lead to a long life.
Followed by "lack of desire." Zhuangzi believed that "people can't stop craving, but can't indulge", and indulgence will lead to troubles and diseases. He pointed out that less sexual desire will not harm the spirit and mind, less appetite will not harm the spirit and mind, and less official desire will not be sad.
Once again, it is "quiet". Zhuangzi advocated "keeping healthy in silence" and often advised people to learn meditation with head empty, peace of mind and relaxation as the main point. He believes that if people can't be quiet all day and their thoughts can't escape, they will get sick. He advocates that people should pay attention to tempering their self-control ability and create opportunities to calm down from time to time when they are emotional.
Finally, there is "optimism". Zhuangzi advocates "harmony without difference, no sorrow and joy", optimism and open-mindedness, and eternal youth. He once metaphorically said that the pheasants in Shui Ze are happy and optimistic, so they can live; When a bird is kept in a cage, its feathers will wither, its will will be depressed, its head will not sing, and it will be difficult to live. If people are imprisoned in mental depression, they will be sad and harmful to health.
