From Mencius Teng Wengong, the original text is: "Either toil or toil. Those who work hard govern others, and those who work hard govern others. Doctors eat people, and doctors eat people: the universal significance of the world is also. "

Literally, people who do mental work are managed by others, and people who do manual work are managed by others.

In fact, Mencius aimed at the study of Xu Xing, a scholar of Shennong. The purpose is to emphasize that there must be a division of labor in the world, and it is impossible for a person to do all kinds of things in the world alone.
