Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
gang min » gong min, chang min, sang minh
tang min » chang min, sang minh, yang mind
wong siu » wong shiu, kong siu, wong sau
li liu » liu liu, li li, li lu
scham » cham, schau

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 ((li liu) OR (li lin)) ((gang min) OR (tang min)) ((wong siu) OR (von scham)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang ((li liu) or (li lin)) ((gang min) OR (tang min)) ((wong siu) or (von scham)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang ((li liu) or (li lin)) ((gang min) OR (tang min)) ((wong siu) or (von scham)) ;*.
