How it's used

This phrase functions as a set slogan or guiding principle rather than a casual verb phrase. It is most commonly encountered in formal settings like public health campaigns, workplace safety guidelines, or institutional policy documents. While it sounds quite serious, it is occasionally used in daily conversation to emphasize that being proactive is better than fixing problems after they arise.

Examples

You should focus on prevention in life, don't wait until you're sick to see a doctor.
The company policy is to prioritize prevention and avoid accidents as much as possible.

Common phrases

prevention is primary, treatment is secondary

Common mistake

Learners often try to use this as a standard verb phrase, but it is grammatically rigid and acts more like a noun phrase or a motto. It does not take common Cantonese aspect markers like 咗 or 過, and it sounds unnatural if you try to insert it into a simple sentence about a specific, minor action.
