Perhaps you should try some spelling variations:
wang wang » wang yang, wang liang, wang yan
wang yong » wang yang, wang hyoung, wang yan
kang hay » eang hay, kang han, dang hai
nan yan » nan ya, wang yan, qian yan
yan dan » dan dana, yan clan, yan guan
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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 wang) OR (wang yong)) nan yan dan ((yang xi) OR (yang yi)) kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yong)) nan yan dan ((yang xi) OR (yang yi)) kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yong)) nan yan dan ((yang xi) OR (yang yi)) kang hay ;*.
