Perhaps you should try some spelling variations:
yong yang » dong yang, ying yang, kyoung yang
yang yang » wang yang, wang yan
liu gang » liu gangs, liu yang, li gang
gang min » gong min, tang min, chang min
wong sau » wong sam, wong siu, wong shiu
lin liu » liu liu, lili liu, lin ling
sar » sara, star, saur

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