Perhaps you should try some spelling variations:
wang yang » wang liang, wang yanling
fang yuan » wang yuhan, meng yuan, tang yun
yuan tan » huan t'an, yuan kang, yuan ting
tan yang » dan yang, tan ying, tan yong
kang hay » eang hay, kang han, kang tae
yang xi » yang di, yang yi, yang jui
hai » hadi, haji, hari

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