How it's used
Refers specifically to the space immediately outside a building or a room, often implying a transition from an enclosed area to an open one. It carries a sense of being just beyond the threshold, rather than a distant location. It is frequently used when someone needs to step out for a private conversation or to escape a crowded indoor environment.
Examples
It's too stuffy inside, let's go outside to get some fresh air.

Common mistake
Do not confuse this with the Mandarin term 外面, which is used in all contexts. While 開便 is common in spoken Cantonese, it is strictly colloquial and should be avoided in formal writing or professional settings.
