Perhaps you should try some spelling variations:
yang muxi » yang xi, yang hui, yang mu
yang jui » yang judy, yang di, yang xi
qian yan » qian jun, qian yi
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
yan jie » yang jie, yan jiu, yang jin
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 hyoung ((yang muxi) OR (yang jui)) qian yan jie ((wong sam) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung ((yang muxi) or (yang jui)) qian yan jie ((wong sam) or (wong siu)) ;*.
