Su Wen's "On Ancient Naivety" pointed out that "ancient people, knowing it, knowing Yin and Yang, eating and drinking well, living a regular life and not being rash, can be in harmony with God and die at the age of 100." Among them, don't work rashly, that is, don't overwork, but combine work and rest moderately. This work includes three aspects: mental work, physical work and housing work.
Introduction to ancient naive theory
The theory of ancient naivety is from the first article of Huangdi Neijing Su Wen, which is a supplementary explanation to the origin and characteristics of Huangdi Neijing. Since ancient times, the beginning of medicine has been the first important paper that Huangdi and Qi Bo talked about how to achieve the goal of health and longevity.
Firstly, this paper discusses the specific reasons why the ancient people who were born naturally and didn't have any man-made chores could remain old for a hundred years, and then talks about the growth and development process of human life, emphasizing the important role of kidney qi, healthy qi and true qi in the human body. Finally, they listed the ideal artistic conception of life such as real people, wise men, saints and sages.
