Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
kang chen » chang chen, jane chen, kang han
yang yue » wang yue, yang yun, yang yi
yang jui » yang judy, yang di, yang xi
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 (yang jui)) man yong jin ((eang hay) OR (((dang hai) OR (kang chen)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang yue) OR (yang jui)) man yong jin ((eang hay) or (((dang hai) or (kang chen)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang yue) OR (yang jui)) man yong jin ((eang hay) or (((dang hai) or (kang chen)))) ;*.
