Perhaps you should try some spelling variations:
yan yang » yang yang, yao yang, dan yang
long shu » cong shu, tong shui, long du
gong hui » tong hui, tong shui, gong si
wang hui » wang hua, wang zhi, wang wei
wai yan » wang yan, wei yang
ii kang » ii gang, ii king, xi kang
ii kann » wie kann, ich kann

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: wai yan yang di ((ii kang) OR (ii kann)) minah ((long shu) OR (((gong hui) OR (wang hui)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan yang di ((ii kang) or (ii kann)) minah ((long shu) or (((gong hui) OR (wang hui)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan yang di ((ii kang) or (ii kann)) minah ((long shu) or (((gong hui) OR (wang hui)))) ;*.
