Perhaps you should try some spelling variations:
wang tan » wang yan, wang ban, wang dan
tan yang » dan yang, tan ying, tan yong
kang min » kan min, tang min, kang minah
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew
yang xi » yang di, yang yi, yang jui
wu kang » wu guang
xi wu » yi wu, li wu, xi bu

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 tan yang xi wu kang min ((kong siu) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang tan yang xi wu kang min ((kong siu) or (wong siu)) ;*.
