Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
kong siu » kong eiu, wong siu, dong sin
kang min » tang min, kang minah, kyung min
yang yi » yang di, yang xi, yang jui
kan min » han min, kian ming, kyaw min
yi xu » yi wu

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 yidan yang yi xu ((kang min) OR (kan min)) ((((wong sau) OR (wong sam))) OR (kong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan yang yi xu ((kang min) or (kan min)) ((((wong sau) or (wong sam))) or (kong siu)) ;*.
