Write a paragraph with a famous saying in the Analects of Confucius.

I don't know what kind of words you need. Here's my opinion on the phrase "review the past and learn something new, so I can be a teacher" for your reference.

A person who can review the past and learn something new shows that he is thoughtful and methodical, and has learned while thinking. "Reviewing the past" is not to repeat or repeat what has been learned, but to think about what has been learned, and at the same time to explore and understand new knowledge in thinking, so that we can "know the new" with the continuous development and improvement of our ideological understanding. Of course, such people will also carry forward their own ideological understanding, and they can play the role of teachers whether they are apprentices or not. As for those who can review the old and learn new things, they should be treated as teachers and learn from them. Of course, if you can do this, then you can also play the role of a teacher.
