Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
wan yang » wang yang, yang yang, wang yan
yang hua » wang hua, yang jui, wang hui
yang jin » ying jin, shang jin, yang di
yang jun » yang jui, pang jun, yang judy
wong sau » kong sar
rene » irene, rent, gene

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 yang) OR (wang yong)) yang hua rene ((yang jin) OR (yang jun)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yang) OR (wang yong)) yang hua rene ((yang jin) or (yang jun)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yang) OR (wang yong)) yang hua rene ((yang jin) or (yang jun)) wong sau ;*.
