How it's used
Focuses on the duration of an event spanning the entire night, often implying that the speaker feels the time was long or that the action was continuous. It is frequently paired with the particle 都 to emphasize that nothing else happened or that the state remained unchanged throughout the duration. Use this when describing activities like working, partying, or worrying that kept you up until dawn.

Common mistake
Do not confuse this with the Mandarin term 整晚, which is less common in spoken Cantonese. Learners sometimes mistakenly use 晚 as a standalone noun for night in this context, but 成晚 acts as a temporal adverbial phrase and does not require additional particles like 喺.
