From the perspective of primitive society, people's survival skills such as hunting and picking wild fruits were passed down through word of mouth, which was the initial form of education.

In slave society, education is divided into culture and art education of the upper class and labor skills education of the lower class. Although the content is different, the essence is to convey the accumulated knowledge and experience of human beings. Feudal society and slave society are basically the same. People's practical activities of survival, whether they like it or not, are being educated in all aspects.

Therefore, education is the basic form of human practical activities.
