Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang shiyong
fang yuan » wang yuhan, meng yuan, tang yun
yan yuan » yan guan, yan clan, yan kun
dan yang » daun yang, tan yang, wang yang
kang hay » eang hay, kang han, dang hai
nan yan » nan ya, qian yan, nana yaa
yang xi » yang di, yang yi, yang jui
xi kang » jin kang, xi zhang

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