When we were young, our parents were the umbrella of our tender hearts. They blocked all kinds of darkness and told us many beautiful fairy tales, including princes and princesses, heroes and beautiful women. After school, the teacher is the builder of our systematic cognition. They discard the dross and take the essence, teach us science, art and philosophy, and teach us Einstein and Montesquieu.

What about social education? Contrary to the first two, cruel beauty is everywhere.
