How to say "Good night" in Chinese

晚安 (wǎn'ān) is a compound of 晚 (wǎn) meaning "night" and 安 (ān) meaning "peace". It is a fixed greeting used to wish someone a peaceful night.

Use 晚安 when saying goodbye at night or before going to bed. It is polite and suitable for both formal and informal settings. Avoid using it during the day; instead, use 你好 (nǐ hǎo) or 再见 (zàijiàn).
