In Cantonese, 晚安 (wǎn'ān) at bedtime is 早唞 (zou2 tau2), "rest early". The rule: Mandarin says good night with 晚安; Hong Kong speech uses 早唞 zou2 tau2 when someone is going to bed or leaving for the night, and keeps 晚安 maan5 on1 for writing, messages and broadcasts. The same word turns up in the dictionary as 早抖, an alternative spelling of the same sound. Use the pinyin converter to check Mandarin tone marks while you compare.
| If you'd say (Mandarin) | Say (Cantonese) | Notes |
|---|---|---|
| 晚安 wǎn'ān (good night) | 早唞 zou2 tau2 | The spoken bedtime farewell |
| 晚安 wǎn'ān (good night) | 晚安 maan5 on1 | Same characters; written cards, chat messages, broadcasts |
| 睡覺 shuìjiào (to sleep) | 瞓覺 fan3 gaau3 | 瞓 (fan3) replaces 睡 in everyday speech |
| 晚上 wǎnshang (evening, night) | 夜晚 je6 maan5 | The spoken word for night |
| 宵夜 xiāoyè (late-night snack) | 宵夜 siu1 je6 | Same word, new reading |
| 午安 wǔ'ān (good afternoon) | 午安 ng5 on1 | Exists, but heard on radio and in classrooms rather than on the street |
| Situation | Say | Why |
|---|---|---|
| Hanging up on mum late at night | 早唞 | The family bedtime farewell |
| Leaving friends after a late dinner | 早唞 | "Rest early", a friendly sign-off |
| A goodnight text | 晚安 | Written register; very common in chat |
| A radio host signing off | 晚安 | Broadcast-formal |
| Passing a neighbour in the lift at 7pm | 你好 or a nod | It is not bedtime yet, so no good night |
| Morning greeting instead | 早晨 | See zǎoshang hǎo in Cantonese |
Using 早唞 as a greeting when you arrive. It means rest early, so it only works when someone is leaving for bed. The other slip is the reverse: saying a stiff 晚安 to your family at home, where 早唞 is what they expect. Both are understood, but the first gets a laugh and the second sounds like a television announcer.
