This is a frequent pitfall for people new to Hong Kong: using do1 ze6 for every “thank you” situation. Common real life usage in Hong Kong: ✅ m4 goi1 / m4 goi1 saai3 Scenarios: receiving service, small favours, passing through crowds, interactions with shop staff. ✅ do1 ze6 / do1 ze6 saai3 Scenarios: receiving gifts or substantial favours. This is generally not used for ordinary daily shop service. Two additional useful phrases: 對唔住 deoi3 m4 zyu6 — Sorry / Excuse me 冇所謂 mou5 so2 wai6 — It’s okay Understanding these polite expressions helps learners behave more naturally in local life interactions. #Cantonese #HongKongculture #Cantonesephrases
