How it's used

This idiom describes a situation where threats or tricks are so numerous or unpredictable that defensive measures become futile. It is frequently used in contexts involving scams, cyber security, or competitive strategies where the opponent holds a clear advantage in speed or variety. Unlike simple defensive terms, it carries a sense of helplessness or being overwhelmed by the sheer scale of the challenge.

Examples

This type of computer virus mutates so fast, how can one possibly guard against it?

Common phrases

making it impossible for people to guard against

Common mistake

Learners often mistake this for a simple verb meaning to defend, but it is a fixed four character idiom that functions as an adjective or predicate. It cannot be split by aspect markers like 咗 or 緊.
