Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
kang min » tang min, kang minah, kyung min
wong sau » wong shiu, wong lai, kong sar
wong sam » wong lai, kong sar, von sam
wong siu » wong shiu, kong siu, wong siew
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 (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan yang yi xu ((kang min) or (kan min)) ((((wong sau) OR (wong sam))) or (wong 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 (wong siu)) ;*.
