The teacher said: isn't it nice to have the opportunity to practice theory at some time? Isn't it a pleasure for people who appreciate their own theories to come from afar? No one understands my theory and is not angry. Isn't such behavior a noble person?

I remember when I was at school, this article was required to be recited in full, but the teacher's explanation at that time was really confusing, so I heard that the Analects of Confucius was restored by a group of old people. I have no doubt at all, but now I have to re-examine this masterpiece.

This is the first paragraph of the Analects of Confucius. Through this passage, I clearly saw a suspicious educator, a frustrated politician, consoling himself sadly. As long as the theory has a chance to put it into practice, I will feel happy in my heart. If someone who understands and appreciates me comes to see me and talk to me, I will be very happy. Even if no one understands and appreciates me, I won't be angry, because I am a noble gentleman.
