Perhaps you should try some spelling variations:
yan wang » yuan wang, yang yang, qian wang
yang jie » yang jin, yang di, yang jui
wong siu » wong shiu, kong siu, wong siew
wong sau » wong sam, wong shiu, wong lai
nan yan » nan ya, wang yan, qian yan
hua ren » hua chen
yan jie » yan jiu, yang jin, huan jie
von sam » von sa, von sap, von scham

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: nan yan wang hua ren ((yan jie) OR (yang jie)) ((von sam) OR (((wong siu) OR (wong sau)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan wang hua ren ((yan jie) OR (yang jie)) ((von sam) or (((wong siu) or (wong sau)))) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan wang hua ren ((yan jie) OR (yang jie)) ((von sam) or (((wong siu) or (wong sau)))) ;*.
