How it's used

Describes someone who forgets the kindness or support they received from others, often implying a betrayal of trust. It carries a strong moral judgment and is typically used when someone acts selfishly after being helped. The term focuses specifically on the lack of gratitude or loyalty toward a benefactor.

Common phrases

Common mistake

Do not confuse this with 冇心, which simply means not having the intention or desire to do something. 冇本心 carries a much heavier weight of moral failure and ingratitude.
