How it's used
Primarily used in formal or scientific contexts to describe atmospheric conditions or gas density. While it is understood in spoken Cantonese, it sounds quite academic or literary, so it is rarely used in casual small talk unless discussing geography or mountain climbing.
Examples
The air is thin up on the mountain, I feel out of breath just walking.
Do you know why the air is thin in high-altitude places?
