Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
kang chen » chang chen, jane chen, tang chun
kang han » kong hang, zhang han, dang hai
yan yuan » yan guan, fang yuan, nan yan
yap yun » yang yun, yau yung
yan kun » yan guan
yang xi » yang di, yang yi, 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 yong ((((yan kun) OR (yap yun))) OR (yan yuan)) wang yang xi ((kang han) OR (kang chen)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((((yan kun) or (yap yun))) or (yan yuan)) wang yang xi ((kang han) OR (kang chen)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan kun) or (yap yun))) or (yan yuan)) wang yang xi ((kang han) OR (kang chen)) ;*.
