Famous sayings have a profound influence on future generations.

Angry: I want to find a solution but can't. Qiu: I want to say something but don't know how to say it. Three sentences of "Give a Corner": Give a corner as an example. Tell the person who is learning, and if he cannot infer the other three angles, there is no need to teach him any more. Because he doesn't think carefully.
