Perhaps you should try some spelling variations:
chia rana » chia lan
tan chia » tuan china, than china, can china
yang jui » yang di, 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
yang xi » yang di, yang yi

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