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

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.
