Huangdi Neijing is a theoretical monograph on Taoist health preservation, a precious legacy left by Taoist culture to future generations, and a golden key to open the treasure house of health preservation. Natural Taoism is one of the core values of Taoism.

Taoism believes that the natural movement and change of the universe is a metaphysical and eternal objective law, which is the highest realm pursued by human beings. Facing the universe and nature, people must strive to achieve nothing, nothing and nothing. Creating emptiness and keeping quiet is based on Dafa. Imitate the fine quality of water: benefit everything without striving for merit. Being good as water is the fundamental law of Taoism and nature.

The unity of heaven and man is a concrete law for Taoism to conform to and understand the nature of the universe. When the sun rises, the human body's yang begins to rise, and when the sun sets, the human body's yang begins to hide. This law requires people to do things in the morning and have a rest in the morning. Spring is life, so sow; When summer is long, it is lush; Autumn is harvest, you have to cut it with a knife; If you hide in winter, you have to go into the warehouse. Always follow the natural rhythm of the universe to live and nurture your life.
