How it works
The word '务必' is a formal adverb used to express a strong command, request, or necessity. It is typically used in professional contexts, official documents, or when the speaker wants to emphasize that an action is mandatory and must not be neglected.

Common mistakes
Avoid using '务必' in casual, daily conversations with close friends as it can sound overly stern or demanding; use '一定要' or '记得' instead.
Tip
Think of '务必' as a formal upgrade to '必须' (must). It is often preceded by '请' (please) to soften the tone while maintaining the sense of urgency.
