Perhaps you should try some spelling variations:
ying yang » yang yang, yin yang, ying chang
juan rene » juan meng, juan rana
yong yan » yang yang, dong yang, yong yoon
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau

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 yan) OR (ying yang)) juan rene ((yang jun) OR (yang jui)) ((wong sam) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) OR (ying yang)) juan rene ((yang jun) or (yang jui)) ((wong sam) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yan) OR (ying yang)) juan rene ((yang jun) or (yang jui)) ((wong sam) or (wong siu)) ;*.
