Broadly speaking, all activities that enhance people's knowledge and skills and influence people's thoughts have educational functions. However, unlike other social activities, education in a broad sense refers to social activities whose direct purpose is to influence people's physical and mental development. Education in a narrow sense mainly refers to school education, which is an activity that educators exert influence on the body and mind of the educated in a planned, purposeful and organized way according to certain social requirements, and urge them to change in the expected direction.
