How it's used

Appears almost exclusively in written headers or formal signage rather than in spoken conversation. It functions as a noun to introduce a list of rules or essential information for a specific activity or place. When used in speech, it often sounds stiff or overly bureaucratic, so it is usually reserved for official instructions.

Common mistake

Learners often mistake this for a verb meaning 'must know', but it is strictly a noun in Cantonese. You cannot use it to say 'you must know this' in a sentence, as that would require different phrasing like 你一定要知.
