Judging from the existing literature, the person who first put forward the theory of atrioventricular health preservation should be Laozi in the Spring and Autumn Period. Laozi brilliantly put forward the fundamental viewpoint of abstinence and essence preservation, which revealed the essence of human life and became the theoretical source of China's atrioventricular regimen for thousands of years. Although there are various theories, viewpoints and methods in later generations, they all take it as the purpose of grasping essence and accepting qi, and no matter doctors, Taoists and Confucians dare to violate it.
