Perhaps you should try some spelling variations:
zhen yong » zheng rong, zheng cong, zheng song
chen yong » chen rong, chen yang, chen ping
yang jui » yang judy, yang di, yang yi
kim dong » kim song, kim jong, kim young
yang xi » yang di, yang yi
dong su » dong xu, rong su, dong sin
qian » ian, kian, jian

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: qian rong ((yang jui) or (yang xi)) ((zhen yong) OR (chen yong)) kim dong su ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian rong ((yang jui) OR (yang xi)) ((zhen yong) OR (chen yong)) kim dong su ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian rong ((yang jui) or (yang xi)) ((zhen yong) OR (chen yong)) kim dong su ;*".
