How it's used
This idiom carries a formal and cautionary tone, often used to warn someone about the permanence of their speech. While it originates from classical literature, it remains a standard way in modern Cantonese to emphasize that spoken words are like horses pulling a chariot that cannot be stopped once they start running. It is most effective when used in serious advice or when someone is about to regret a hasty comment.
Examples
Once you say it, you can't take it back, think carefully before you speak.

Common mistake
