How it's used
Beyond the literal meaning of a red banner, this term is frequently used in the context of beach safety to indicate dangerous swimming conditions. It carries a strong sense of immediate warning or prohibition. While it can metaphorically refer to warning signs in other contexts, its most common daily usage remains linked to water safety and weather alerts.

Common mistake
Do not confuse this with the metaphorical red flag used in English to describe a warning sign in a relationship or person, as that idiom does not translate directly into Cantonese using this term.
