Perhaps you should try some spelling variations:
yong yang » dong yang, ying yang, kyoung yang
yang yang » wang yang, wang yan
wong shiu » wong siu, cong shu, song shin
liu gang » liu gangs, liu yang, li gang
gang min » gong min, tang min, chang min
wong sau » wong sam, wong siu, wong lai
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 (yang yang)) liu liu gang min ((((wong sau) OR (wong shiu))) OR (von sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) OR (yang yang)) liu liu gang min ((((wong sau) or (wong shiu))) or (von sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) OR (yang yang)) liu liu gang min ((((wong sau) or (wong shiu))) or (von sam)) ;*.
