Perhaps you should try some spelling variations:
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
yan ban » can bank, tan bann, wang ban
ban hua » ban bua, tan hua, wang hua
hua ren » hua chen
yan jie » yang jie, yang jin, huan jie
yan jiu » yang jie, yang jin, pang jiu
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 yan ban hua ren ((yan jie) OR (yan jiu)) ((wong sam) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ban hua ren ((yan jie) OR (yan jiu)) ((wong sam) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ban hua ren ((yan jie) OR (yan jiu)) ((wong sam) or (wong siu)) ;*.
