Confucius’ famous aphorisms about correcting mistakes:

1. Isn’t it true that one should learn and practice from time to time? Isn’t it great to have friends from far away? Isn't it a gentleman if a person doesn't know something but doesn't get upset?

2. Clever words and charming words, fresh and benevolent!

3. I will examine myself three times every day: Are I being unfaithful to others? Make friends but don’t believe it? Can't you learn Hu?

4. A gentleman has nothing to eat and nothing to live in, and he has no desire to live in peace. He is sensitive to things but cautious in speaking.

5. Don’t worry about what others don’t know, and worry about what others don’t know.

6. The Three Hundred Poems can be summed up in one sentence, saying: "Thoughts are innocent."

7. I am determined to learn when I am fifteen, and I stand up at thirty. At forty, there is no confusion; at fifty, one knows the destiny; at sixty, one's ears are attuned; at seventy, one follows one's heart's desires without exceeding the rules.

8. If you review the past and learn the new, you can become a teacher.

9. If you learn without thinking, you will be in vain; if you think without learning, you will be in danger.

10. To know something is to know it, and to know something is to know it, and to know something is to know it.

11. If you raise the straight and wrong, the people will obey; if you raise the straight and wrong, the people will not obey.

12. Eight people dancing in the court are tolerable, but who can’t be tolerated!
