In which dynasty was the academy formally formed as an educational institution?
Academy education is the most distinctive form of educational organization in Song, Yuan and Ming Dynasties. The word "academy" first appeared in the Tang Dynasty. But at that time, the academy was mainly a place for compiling books, collecting books and reading. As an educational place with a certain scale, the academy did not appear until the Song Dynasty. At that time, just after the Five Dynasties and Ten Kingdoms War, culture and education needed to be revitalized, and some thinkers also needed their own propaganda positions. Academy education with private teaching as the core came into being. Academy education in Song Dynasty, with its educational system and perfect educational organization form, showed a completely different face from ancient private schools. In addition, the academy education in Song Dynasty was quite different from the official study.
