Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
kong heng » kong hang, kong hong, dong sheng
yang yue » wang yue, yang jui, yang yi
yang yun » yang jun, tang yun, yang yang
man yong » tan yong, wang yong, man houng
yong jin » yang jin, ying jin, song jin
eang hay » dang hai, 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 (yang yun)) man yong jin ((eang hay) OR (kong heng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang yue) OR (yang yun)) man yong jin ((eang hay) or (kong heng)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang yue) OR (yang yun)) man yong jin ((eang hay) or (kong heng)) ;*.
