Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang yang » wang yang, wang yan
gang dean » yang dean, gang der, gang des
yang jui » yang judy, yang yi
dean non » can non
non scid » non sit
yang xi » yang yi
yi gang » ii gang, i gang, li gang

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: lang hyoung ((((((yang di) OR (yang xi))) OR (yang yang))) OR (yang jui)) yi gang dean non scid ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((((yang di) or (yang xi))) or (yang yang))) or (yang jui)) yi gang dean non scid ;*.
