yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
nan yan » nan ya, wang yan, qian yan
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
yang xi » yang di, yang yi, yang jui

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 nan yan hua ren ((yang jin) OR (yang xi)) ((wong sau) OR (wong sam)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang nan yan hua ren ((yang jin) or (yang xi)) ((wong sau) or (wong sam)) ;*.
