Perhaps you should try some spelling variations:
wang yong » wang yang, wang yan, wang shiyong
hua rene » hua ren, juan rene
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
yan hua » tan hua, ya hua, wang hua
yang xi » yang di, yang yi
won sau » wong sau, wong sam, wong siu

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