How it's used

This idiom is used to emphasize a complete lack of connection between two subjects, often implying that comparing them is illogical or absurd. It is frequently used in arguments or debates to dismiss a point that is considered irrelevant or off-topic. Despite its classical origins, it is fully integrated into modern spoken Cantonese.

Examples

These two things are completely unrelated, how can you compare them?

Common mistake

Learners often mistakenly use this phrase to mean 'different' or 'not the same', but it specifically denotes a total lack of logical relationship or connection, not just a difference in characteristics.
