The reason why China paid attention to labor and laborers in ancient times.

Labor produces wisdom, which enables human beings to exercise their hands-on ability in the process of evolution. Labor is the foundation of the survival and development of human society, which mainly refers to the process of producing material materials, and usually refers to human movements that can export labor quantity or labor value to the outside world. Labor is the only means for people to survive and develop themselves.

According to the traditional labor classification theory, labor can be divided into two categories: mental labor and manual labor.

In the process of labor, on the one hand, human beings form information through the transformation of behavior and thinking mode, choose information through value judgment and evaluation, and store and disseminate information through experience and ability.

On the other hand, information is formed by establishing, developing and perfecting various forms of extended dissipative structures, information is selected by value judgment and evaluation, and information is stored and disseminated by scientific and technological means. Third, labor promotes the division of labor between hands and feet and enables people to learn how to make and use tools. Labor promotes the production of language and accelerates the production and dissemination of information; Labor promotes the evolution of brain and body and accelerates the accumulation and processing of information.
