Perhaps you should try some spelling variations:
kang minah » sang minh
wang yong » wang yang, wang hyoung, wang yan
gong min » jong min, song min, gong meng
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yong li » song li, yang li, yong kim
li hua » li hui, lu hua

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 yong li hua (rene OR gene) ((gong min) OR (kang minah)) ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong li hua (rene or gene) ((gong min) or (kang minah)) ((wong sau) OR (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong li hua (rene or gene) ((gong min) or (kang minah)) ((wong sau) OR (wong sam)) ;*.
