How it's used
This idiom carries a slightly literary or formal tone despite being used in everyday speech to describe intense activities. It implies a sense of dedication or obsession, often used when someone is working, studying, or partying without stopping until sunrise. It is more descriptive and emphatic than simply saying 成晚.
Examples
They played video games all night long, now they can't even open their eyes.
Do you really have to pull an all-nighter to finish that report?

Common mistake
Learners often mistake this for a simple verb, but it functions as an adverbial phrase describing the duration of an action. Avoid using it for casual sleep, as it specifically highlights the active, non-stop nature of the time spent awake.
