Perhaps you should try some spelling variations:
wan hyoung » wang hyoung, man houng, min hyoung
yang hui » wang hui, yang muxi, zhang hui
wang wei » zhang wei, wang zhi
yang jui » yang judy, yang di, yang xi
jin ying » li ying
ying jae » myung jae, ying jin
jae cong » jae song, jae yong, jae young
yang mu » yang du, yang muxi, yang jun

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: wan hyoung ((((((yang hui) OR (yang mu))) OR (wang wei))) OR (yang jui)) jin ying jae cong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung ((((((yang hui) or (yang mu))) or (wang wei))) or (yang jui)) jin ying jae cong shu ;*.
