How it's used
This idiom carries a slightly literary or dramatic flair, often used to emphasize how quickly time slips away or how rapidly situations shift. It is more evocative than simply saying 好快, making it a common choice in reflective speech or storytelling. While it describes a duration, it functions more like an adverbial phrase of time rather than a noun.
Examples
The world is unpredictable; things often change completely in an instant.
The time you thought was so long actually passed in the blink of an eye.

Common mistake
Learners sometimes mistakenly use this to describe physical speed, such as running fast, but it is strictly reserved for the passage of time or the suddenness of an event.
