Perhaps you should try some spelling variations:
seung joon » kyung joon, seung won, seung youn
seung yeon » jeong yeon, seung won, seung youn
wang ying » wang yang, wang jing, wang ning
wang yong » wang yang, wang hyoung, wang yan
yang xi » yang yi, yang jui
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) OR (yang di)) test a min ((seung yeon) OR (seung joon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) or (wang yong)) ((yang xi) OR (yang di)) test a min ((seung yeon) or (seung joon)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) or (wang yong)) ((yang xi) OR (yang di)) test a min ((seung yeon) or (seung joon)) ;*.
