Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang wang » wang yang, wang liang, wang yan
yang hui » yang jui, wang hui, yang muxi
yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yan jui » yang jui, 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: wang wang ((yan jui) OR (yang hui)) irene ((yang jin) OR (yang yang)) ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((yan jui) OR (yang hui)) irene ((yang jin) or (yang yang)) ((wong sau) or (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang ((yan jui) OR (yang hui)) irene ((yang jin) or (yang yang)) ((wong sau) or (wong sam)) ;*.
