Sentences in The Analects in which Confucian disciples warned themselves to constantly reflect.

In the Analects of Confucius, when it comes to the content that Confucius' disciples warned themselves to constantly reflect, most people will think of what Cher recorded:

Zeng Zi said, "I save myself in three provinces. Is it cheating for others? Don't believe in making friends? I can't get used to it.

The content of this passage is very specific, that is, insist on reflecting on your own practices in asking for help, making friends and passing on scriptures, so as to constantly improve yourself and sublimate yourself. But apart from this passage, Xia Zi's remarks in Zhang Zi, such as "knowing his death in the day, not forgetting his ability in the month" and "learning with certainty, asking and thinking", are also self-reflective.
