How it's used
This idiom is a classic example of a chengyu that is used to mock someone for their arrogance or lack of self-awareness. It specifically targets those who attempt to demonstrate knowledge or skill to someone who is clearly far more experienced or qualified than they are. It carries a strong sense of irony and is often used as a warning to keep one's ego in check.

Common mistake
Learners often mistake this for a simple description of teaching, but it is strictly derogatory. It should never be used to describe a genuine attempt to learn from a master, as it implies the speaker is foolishly trying to outshine the expert.
