Perhaps you should try some spelling variations:
wang ying » wang yang, wang jing, wang ning
wang yong » wang yang, wang hyoung, wang yan
dan yang » daun yang, tan yang, wang yang
yang jie » yang jin, yang di, yang jui
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
hua dan » hua ban

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: wen ((wang ying) OR (wang yong)) hua dan yang jie ((wong sam) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wen ((wang ying) OR (wang yong)) hua dan yang jie ((wong sam) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wen ((wang ying) OR (wang yong)) hua dan yang jie ((wong sam) or (wong siu)) ;*.
