How it's used
Refers to any sleeveless upper garment, ranging from casual cotton tank tops worn at home to formal waistcoats worn over a dress shirt. Unlike English where vest and tank top are distinct, Cantonese uses this single term for both styles. It is common to specify the material or context if you need to distinguish between a casual undershirt and a formal piece.

Common mistake
Do not confuse this with the verb 背心, which can sometimes appear in older literary texts meaning to be mindful or to take to heart; in modern daily speech, it is strictly a noun for the garment.
