Perhaps you should try some spelling variations:
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
yan ban » can bank, tan bann, wang ban
bua ren » hua ren
yan jie » yang jie, huan jie, tang jie
yan jiu » yang jie, 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 bua ren ((((yan jie) OR (yang jin))) OR (yan jiu)) ((wong sam) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ban bua ren ((((yan jie) or (yang jin))) or (yan jiu)) ((wong sam) or (wong siu)) ;*.
