How it's used

This idiom carries a strong sense of frustration and disappointment, often used when someone repeatedly ignores constructive feedback. It implies that the person has been given ample guidance but chooses to remain stuck in their ways. It is frequently used in interpersonal conflicts or when criticizing someone's persistent bad habits.

Examples

He is truly incorrigible, no matter how much you tell him, he won't listen.
How much longer are you going to remain stubborn and refuse to learn?

Common phrases

refusing to listen no matter how many times it is said

Common mistake

Do not confuse this with the similar sounding idiom 教而不善, which is often mistakenly used to mean someone who is bad at teaching. In Cantonese, it specifically describes the student or the person receiving the advice, not the teacher.
