Education, in my understanding, is to spread one's own knowledge so that others can receive it and be inspired by it. In my opinion, the forms of education are mainly divided into the following two types.

The first is tangible education.

Just like children, when they were young, they would imitate some actions of adults. Parents often play mobile phones at home, so in a subtle way, children often want to play mobile phones, because he knows from their parents' behavior that this item should be playable. Another example is a mother who loves beauty. She often wears makeup at home, so her children often see her putting those things on her face. After a period of time, he will learn to put those cosmetics on his face, although in most cases he has no idea what these things can do.

The second is intangible education.

Intangible education includes non-behavioral education such as astronomy, geography, world outlook and values besides the vocabulary learned in school. Although this kind of education is intangible, it will form a system in the minds of the educated and teach people how to understand and transform the world.
