Perhaps you should try some spelling variations:
wong sam » wong sau, wong lai, von sam
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, nan yan, wai yan
yan tan » tan tan, yan clan, yan guan
tan hua » tuan hua, wang hua, tan chia
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: wan yan tan hua ren yan jie ((((wong sam) OR (kong sar))) OR (kong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan tan hua ren yan jie ((((wong sam) or (kong sar))) or (kong siu)) ;*.
