Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
kin seung » kim eung, kin keong
test awt » test auf, test a
nan yan » wang yan, qian yan, dan yang
yang ai » yang di, yang xi, yang li
yang yi » yang di, yang xi, yang jui
test ke » test bed, test der, test kit
nan ya » nana yaa

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: ((nan yan) OR (nan ya)) ((yang ai) OR (yang yi)) ((test ke) OR (test awt)) kin seung yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nan yan) OR (nan ya)) ((yang ai) or (yang yi)) ((test ke) or (test awt)) kin seung yeon ;~".
• Adding a wildcard symbol may retrieve word variants: ((nan yan) OR (nan ya)) ((yang ai) or (yang yi)) ((test ke) or (test awt)) kin seung yeon ;*.
