Education is the whole process of training a new generation to engage in social life, and it is also the key link to inherit and carry forward the production experience of human society. Mainly refers to the process of cultivating school-age children, teenagers and young people. Broadly speaking, all activities that enhance people's knowledge and skills and affect people's ideology and morality are education.

Personally, I think this understanding is enough at the philosophical level. Please refer to Baidu Encyclopedia for details.
