Confucius said, "Don't enlighten him until he tries to understand." Don't inspire him until he knows something but can't express it perfectly. If he can't draw inferences from others, don't give him repeated examples. "

No anger, no anger, no sorrow, no hair

The Analects of Confucius said: "Don't be angry, don't be angry, don't be angry, don't let a corner, don't occupy a corner, and you will never have it again." This is an important famous saying of Confucius about heuristic teaching, which has a far-reaching influence on later generations.

Anger: I tried to get through but failed. I want to say it, but I don't know how to say it. Take one corner as an example to tell the learner, but he can't infer the other three corners, so he doesn't need to be taught because he doesn't think hard.

The famous sentence "Don't be angry, don't be angry, don't be angry, don't be angry, don't be angry" says: If students don't think and have some experience, they won't enlighten them when they want to say it; If you don't think hard, you can't figure it out. Don't motivate him.

"Not angry." "Don't rush, don't send" is often used to explain that students should be strict, let them think positively first, and then inspire them in time.
