In Cantonese, 早上好 (zǎoshang hǎo) is 早晨 (zou2 san4). The rule: Mandarin builds good morning from "morning" plus "good"; Hong Kong has a set greeting of its own that you say before midday. 早晨 zou2 san4 is the one locals use. The Mandarin-style 早上好 zou2 soeng6 hou2 and 早安 zou2 on1 are listed in the dictionary and people will understand you, but they read as written or translated. Check the Mandarin tone marks with the pinyin converter while you compare.

| Situation | Say | Why |
|---|---|---|
| Walking into the office at 9am | 早晨 | The default morning hello |
| Passing a colleague in the corridor | 早 | Short and casual, like "morning!" |
| Greeting your grandmother at breakfast | 早晨 | Always safe with elders |
| Texting a friend first thing | 早安 | Common in written messages |

Saying 早晨 after midday, or using 早唞 as a morning word. 早晨 (zou2 san4) is only for the morning, and 早唞 (zou2 tau2) means good night. They share the character 早 and nothing else, and mixing them up makes people laugh. The side-by-side comparison is in 早晨 vs 早唞. Second mistake: reading 早上好 aloud as zou2 soeng6 hou2 to a shopkeeper. It is understood, but it sounds like a notice, not a person.
