You can say "좋은 아침" which means "good morning" :D

안녕하세요 - Can mean Good Morning, Good Afternoon, Good Evening. But literally it means "Are you at peace." That's why often you will hear Koreans say it as a question for example. A. 안녕하세요? (Are you at peace?) B. 네, 안녕하세요~?. (Yes, How about you?) 좋은 아침 = Good morning. 좋다 - to be good 아참 - morning You could also use Konglish and say "굿모닝" like this as well. : ) Your best bet is just to use 안녕하세요~ though. ^_^

All at once " 안녕하세요 " :)
