Perhaps you should try some spelling variations:
yong yang » yang yang, ying yang, kyoung yang
dong yang » dong hoang, wang yang, yang yang
chang min » zhang ming, chang mae, chan ming
wong sau » wong sam, wong siu, wong shiu
gang min » gong min, tang min, sang minh
liu liu » liu li, liu lili, lili liu
von sam » von sa, von sap, von scham

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