Education is a kind of inheritance and promotion of human morality, science, technology, knowledge reserve and spiritual realm, and it is also the transmission of human civilization. Broadly speaking, all activities that enhance people's knowledge and skills and affect people's ideology and morality are education. Education in a narrow sense mainly refers to school education, which means that educators exert purposeful, planned and organized influence on the body and mind of the educated according to the requirements of a certain society (or class) and cultivate them into people needed by a certain society (or class).

Education is fundamentally different from social practice and environment;

People's practice is mainly the activity of understanding and transforming the world, while education is entirely the activity of cultivating and transforming people;

Education is not equal to environment, which is purely an external factor of human development, while education contains subjective factors;

The influence of environment on people is spontaneous, while the influence of education on people is conscious.
