Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
chang min » zhang ming, chang mae, chan ming
chan fong » chew fong, chan eng, chan kang
wong shiu » wong siu, cong shu, song shin
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
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: wang yang ((yang jui) OR (yang xi)) liu ((chang min) OR (chan fong)) ((wong shiu) OR (von sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang jui) OR (yang xi)) liu ((chang min) or (chan fong)) ((wong shiu) or (von sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang jui) OR (yang xi)) liu ((chang min) or (chan fong)) ((wong shiu) or (von sam)) ;*.
