Perhaps you should try some spelling variations:
dong hoang » hong hong
hoang yang » huang yang, wang yang, yang yang
jeong yeon » jeong hyeok, jeang yean, seung yeon
seung joon » kyung joon, seung yeon, seung youn
seung won » seung yeon, seung youn, myung won
yang xi » yang di, yang yi, yang jui
xi rest » i rest
kaw min » kyaw min, kan min, law main

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 hoang yang xi rest kaw min ((jeong yeon) OR (((seung won) OR (seung joon)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong hoang yang xi rest kaw min ((jeong yeon) or (((seung won) or (seung joon)))) ;*.
