Three treasures of Taoism: 1. Taoists regard "Tao, Classics and Teachers" as the three treasures of converting to Taoism; 2. Monks regard the "essence, spirit and spirit" of the human body as the three treasures of self-cultivation; 3. "Benevolence, frugality and concession" are three treasures. The three treasures were first seen in the 67th chapter of Lao Zi's Tao Te Ching. In troubled times, those who hold Laozi's three treasures are as independent as dragons, leisurely, steady and ready to go, showing the essence of Taoism.

The three treasures of Taoism reflect Laozi's concern and love for life, and reflect the idea that the king hides his tools in his body and waits for the opportunity. It shows the unique ideological connotation of Taoism, such as quietness, softness, introversion, condensation and concealment.

Tao Te Ching is a work of China before the separation of pre-Qin philosophers in ancient times, and it is an important source of Taoist philosophy. Tao Te Ching is one of the greatest works in the history of China, which has a profound influence on traditional philosophy, science, politics and religion.

The text of Tao Te Ching takes "morality" in the philosophical sense as the main line, and discusses the ways of self-cultivation, governing the country, using troops and keeping in good health, but most of them aim at politics. It is the so-called "inner sage and outer king" theory, which has profound meaning and wide tolerance and is known as the king of all classics.
