Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
wong sau » wong siu, wong shiu, wong lai
dan yang » daun yang, tan yang, wang yang
wong sam » wong lai, kong sar, von sam
ren yang » ren yan, chen yang, pei yang
wang hui » wang hua, wang zhi, wang wei
yang hua » wang hua, yang hui, ying 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 ((yang hua) OR (wang hui)) ((ren yang) OR (dan yang)) jin ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang hua) or (wang hui)) ((ren yang) OR (dan yang)) jin ((wong sau) or (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang hua) or (wang hui)) ((ren yang) OR (dan yang)) jin ((wong sau) or (wong sam)) ;*.
