Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
chan ming » kian ming, chan eng, chan fong
yang jin » yang jie, yang jun, ying jin
tang min » chang min, sang minh, yang mind
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yang li » yang lin, yang di, yang xi

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 ying ((yang li) OR (yang jin)) ju ((tang min) OR (chan ming)) ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang li) or (yang jin)) ju ((tang min) or (chan ming)) ((wong sau) OR (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang li) or (yang jin)) ju ((tang min) or (chan ming)) ((wong sau) OR (wong sam)) ;*.
