Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
qiao can » qian yan, qiao sen
yang jun » yang jui, pang jun, yang jin
wong sam » wong sau, wong lai, kong sar
ta chen » a chen, hua chen
yang xi » yang di, yang jui
yang yi » yang di, yang jui
can ta » can tax, can tb, can take
wang » wing, wan, lang

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 qiao can ta chen ((((yang yang) OR (((yang jun) OR (yang xi))))) OR (yang yi)) wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: wang qiao can ta chen ((((yang yang) or (((yang jun) or (yang xi))))) or (yang yi)) wong sam ;*.
