How it's used
Used when someone wants to emphasize the seriousness or sincerity of a promise. It often carries a sense of gravity, suggesting that the speaker is willing to face consequences if they break their word. It is frequently paired with phrases that indicate the target of the oath, such as 對住天發誓.

Common mistake
Avoid using this for casual promises, as it sounds overly dramatic and intense. It is reserved for significant commitments rather than everyday agreements like meeting for lunch.
