How it's used
Carries a slightly formal or old fashioned tone that feels out of place in casual, modern conversation. It functions as a euphemism, similar to saying relieve oneself in English, and is often used by older generations or in literary contexts to avoid being overly blunt about bodily functions.
Examples
I need to go to the toilet, where is one?

Common phrases
to go to the toilet
Common mistake
Avoid using this in everyday settings with friends or peers, as it sounds stiff and unnatural. Most people simply use 去廁所 or the more specific 大解 or 小解 when they need to be clear.
