Generally speaking, people call education in educational institutions (such as schools, kindergartens, welfare homes, juvenile detention centers and various training courses) social education, while education at home is called family education. At the end of primitive society, there were no schools. More importantly, the education at that time was passed on by word of mouth, and basically it was to teach life skills. So at the end of primitive society, the main task of family education is to educate the younger generation, not social education. You can refer to the relevant content of educational history.
