Perhaps you should try some spelling variations:
hua rana » hear rana, juan rana, hua ban
yang jie » yang jin, yang di, yang xi
yang jui » yang di, yang xi, yang yi
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
wai tan » wai yan, wahid tan
tan tan » tas tan, tin tan, tang tang
tan hua » tuan hua, wang hua, tan chia

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: wai tan tan hua rana ((((yang judy) OR (yang jie))) OR (yang jui)) ((wong sam) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wai tan tan hua rana ((((yang judy) or (yang jie))) or (yang jui)) ((wong sam) or (wong siu)) ;*.
