Perhaps you should try some spelling variations:
clan yuan » yan yuan
yuan ming » yuan ting, kian ming, tuan minh
yan clan » das clan, yan guan, yan yuan
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing OR lang) yan clan yuan ming ((yang jie) OR (yang jui)) ((wong sau) OR (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wing OR lang) yan clan yuan ming ((yang jie) OR (yang jui)) ((wong sau) OR (wong sam)) ;*.
