Perhaps you should try some spelling variations:
wang ban » wang yan, wang dan, wang yang
wong sam » wong lai, kong sar, von sam
wong siu » wong shiu, kong siu, wong siew
wong sau » wong shiu, wong lai, kong sar
yan ban » can bank, tan bann, yan clan
hua ren » hua chen
yan jie » yang jie, yan jiu, yang jin

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: nan ((yan ban) OR (wang ban)) hua ren yan jie ((wong sam) OR (((wong siu) OR (wong sau)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((yan ban) OR (wang ban)) hua ren yan jie ((wong sam) or (((wong siu) or (wong sau)))) ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((yan ban) OR (wang ban)) hua ren yan jie ((wong sam) or (((wong siu) or (wong sau)))) ;*.
