There is such a passage in The Analects of Confucius Yan Yuan. Zi Gong asked his friend, and Confucius said, "Give advice and do a good job. If you can't stop, don't bring disgrace to oneself. " Translated, Zi Gong asked how to get along with friends. Confucius said, "Sincere advice and understanding. Don't listen, that's enough. Don't bring disgrace to oneself. " Confucius suggested that enough is enough.

Confucius' famous exhortation:

1, review the past and learn the new, you can be a teacher.

2, learning without thinking is useless, thinking without learning is dangerous.

3, always learn, what's more? Is it not delightful to have friends coming from distant quarters? Isn't he a completely moral person? Although people may not pay attention to him, he won't feel uneasy.

4, sensitive and eager to learn, not ashamed to ask questions.

5, can't talk to it, and it is a slip of the tongue. Those who know, don't lose people, don't lose words.
