Perhaps you should try some spelling variations:
fang yuan » wang yuhan, wang yan, meng yuan
yang lin » yang jin, wang lin, yang li
man yuan » yan yuan, meng yuan, man can
dan tang » dan yang, dan tabung, tang tang
tang yun » yang yun, chang yun, tang chun
kang hay » eang hay, dang hai, kang tae
kang han » kang chen, kong hang, zhang 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: yang lin ((man yuan) OR (fang yuan)) dan tang yun ((kang hay) OR (kang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang lin ((man yuan) or (fang yuan)) dan tang yun ((kang hay) OR (kang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang lin ((man yuan) or (fang yuan)) dan tang yun ((kang hay) OR (kang han)) ;*.
