What is the significance of the existence of ancient academies?

Academy is a unique form of educational organization in ancient China. It is a private academic research and educational institution, which is relatively independent of government-run schools, mainly founded and sponsored by private individuals, and integrates book proofreading and teaching research. During the Song, Yuan, Ming and Qing Dynasties, academies gradually developed into the most important comprehensive educational research organization form besides official schools. The existence of academy education makes up for the deficiency of feudal official learning and fills the gaps in many academic and cultural research fields. Its rich teaching experience and flexible school-running form have been used for reference by educators in past dynasties. The rich connotation contained in the tradition of academy education is the precious historical wealth of China education.
