The governor thinks that the classic-fate, shun. Du and Zhong here refer to the way of nature. Jing, Chang "You can protect yourself" four sentences-protect your own people and protect your life from punishment; The whole body, save nature, do not kill thoughts; Those who support their relatives, maintain their spirits, have completed their youth and enjoy a natural life.

My life is limited, but so is my knowledge. With the limit, I am in danger! Knowing what you already know is almost enough. Good has no near name, and evil has no near punishment. The Governor thinks that you can protect yourself, live in peace for the rest of your life, support your relatives and live in peace in your old age.

Human life is limited, but knowledge is infinite. Pursuing infinite knowledge with limited life will make them exhausted. In this case, people who pursue knowledge can only be tired. Health-preserving people do good things not to pursue fame and gain, but to do bad things not to violate the criminal law. If they follow the laws of nature as the rules of doing things, they can protect their lives, preserve their nature, preserve their spirit and enjoy the whole world.
