How to say "Por favor" in Vietnamese

In Vietnamese culture, politeness is deeply tied to social hierarchy, age, and context. The phrase Xin vui lòng (literally "please, be happy") is a polite request marker used in formal or neutral situations. It softens a demand or request, making it sound more respectful. Beginners should note that Vietnamese often relies on context and tone—overusing Xin vui lòng in casual settings can sound overly formal or even sarcastic. Always pair it with appropriate titles or honorifics when addressing elders or strangers.

1. Formal requests (to strangers, elders, or in professional settings) Use Xin vui lòng to sound polite when making a request or asking for help. This is the safest default for beginners.

   • Xin vui lòng cho tôi xem thực đơn.
     Please let me see the menu.
   • Xin vui lòng chờ một chút.
     Please wait a moment.

2. Requests to service staff (waiters, shop assistants, etc.) In service industries, Xin vui lòng is expected but often shortened to Làm ơn (a more casual "please") in everyday speech. However, Xin vui lòng remains appropriate for tourists or formal interactions.

   • Xin vui lòng gửi hóa đơn cho tôi.
     Please send me the bill.
   • Xin vui lòng chỉ đường đến bưu điện.
     Please show me the way to the post office.

3. Requests to close family or close friends With people you’re very close to, Xin vui lòng can sound overly formal. Instead, use Làm ơn or simply omit the phrase entirely. Adding it might even sound sarcastic or mocking.

   • Làm ơn đưa tôi cái bánh kia!
     Please pass me that cake!
   • Đóng cửa sổ giùm tôi.
     Close the window for me (no "please" needed).

4. Written requests (emails, signs, or formal notices) In writing, Xin vui lòng is common in instructions, notices, or polite requests. It’s often paired with xin (a humble request marker) for extra politeness.

   • Xin vui lòng đọc kỹ hướng dẫn trước khi sử dụng.
     Please read the instructions carefully before use.
   • Xin vui lòng giữ im lặng trong thư viện.
     Please remain silent in the library.

5. Requests involving favors or asking for help When asking someone to do something for you (especially if they’re not obligated), Xin vui lòng softens the request. Combine it with anh/chị (older sibling/older person) or bác (aunt/uncle) for added politeness.

   • Xin vui lòng giúp tôi một tay được không, chị?
     Could you please help me out, sister?
   • Xin vui lòng cho tôi mượn quyển sách này, bác.
     Please lend me this book, uncle.

👉 Most useful for daily life: Start by memorizing Xin vui lòng for formal or neutral requests. For casual settings, use Làm ơn instead. Always pair it with titles like chị (older sister) or anh (older brother) when addressing elders to show respect.
