Perhaps you should try some spelling variations:
jeong dahyeon » jeong hyeok
jeong yeon » jeong hyeok, jeang yean
seung yeon » seung joon, seung won, seung youn
dong wang » dong yang, hong wang, dong hoang
wang yang » wang yan, wang liang, wang yanling
yang qui » yang jui, yang hui, yang muxi
kan min » han min, kian ming, kyaw min
est » east, west, best

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: dong wang yang qui est kan min ((((jeong yeon) OR (jeong dahyeon))) OR (seung yeon)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong wang yang qui est kan min ((((jeong yeon) or (jeong dahyeon))) or (seung yeon)) ;*.
