Perhaps you should try some spelling variations:
seung youn » seung won, seung yeon
seung joon » kyung joon, seung won, seung yeon
wang ying » wang yang, wang jing, wang ning
wang yong » wang yang, wang hyoung, wang yan
yang xi » yang di, yang yi, yang jui
xi test » ai test, i test, ii test
test a » test _, test 4, test 5
a min » a main, a mini, a mine

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: ((wang ying) OR (wang yong)) yang xi test a min ((seung youn) OR (seung joon)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang ying) or (wang yong)) yang xi test a min ((seung youn) or (seung joon)) ;*.
