Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, seung yeon
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
hong yeon » dong myeon, hong seo, hong een
test awt » test auf, test a
yang xi » yang di, yang yi, yang jui
xi test » ai test, i test, ii test

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 yong) OR (wang yang)) yang xi test awt tin ((hong yeon) OR (jeong yeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang yang)) yang xi test awt tin ((hong yeon) OR (jeong yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yang)) yang xi test awt tin ((hong yeon) OR (jeong yeon)) ;*.
