Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
kong hang » kong heng, kong hong, kong land
yang yue » yang yun, yang jui, yang yi
wang yue » wong yue, wang hua, wang yan
man yong » tan yong, wang yong, man houng
yong jin » yang jin, ying jin, song jin
eang hay » kang han

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 ying ((yang yue) OR (wang yue)) man yong jin ((((eang hay) OR (dang hai))) OR (kong hang)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang yue) or (wang yue)) man yong jin ((((eang hay) OR (dang hai))) or (kong hang)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang yue) or (wang yue)) man yong jin ((((eang hay) OR (dang hai))) or (kong hang)) ;*.
