Perhaps you should try some spelling variations:
seung joon » kyung joon, seung won, seung youn
seung yeon » jeong yeon, seung won, seung youn
wang jing » wang ning, wang liang, wang yang
yang ai » yang di, yang xi, yang li
yang yi » yang di, yang xi, yang jui
test 5 » test _, test 4
5 min » 5 main, 15 min, _ min

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 jing ((yang ai) OR (yang yi)) test 5 min ((seung yeon) OR (seung joon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jing ((yang ai) or (yang yi)) test 5 min ((seung yeon) OR (seung joon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang jing ((yang ai) or (yang yi)) test 5 min ((seung yeon) OR (seung joon)) ;*.
