What are the traditional ways of working?

A kind of labor is divided into simple labor and complex labor. According to the traditional labor classification theory, labor can be divided into mental labor and manual labor. Due to the inherent existence of human beings, the main contradiction is the contradiction between human consciousness, subject and life ontology. Any human behavior is the external manifestation of this contradiction, which is their comprehensiveness. Therefore, both manual labor and mental labor are in human practical activities, and there is no complete division between manual labor and mental labor. This does not refer to their styles, but their practices.
