Perhaps you should try some spelling variations:
yong yang » yang yang, dong yang, kyoung yang
ying yang » yang yang, yin yang, ying chang
chang min » zhang ming, chang mae, chan ming
wong sau » wong siu, wong shiu, wong lai
gang min » gong min, tang min, sang minh
wong sam » wong lai, kong sar, von sam
liu liu » liu li, liu lili, lili liu

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