Perhaps you should try some spelling variations:
yuan yang » yuan ying, yuan fang, yuan yan
guan yuan » yuan yuan, guan yu, tan yuan
yuan hui » yuan hua, huan hui, yuan hsi
yang yu » yang yi, yang y, kang yu
han bei » zhan bei, nan bei, han bi
yi dai » li dai, yi da, yi bai
yu yi » yu yu, yu ci, yi yi
de ci » de cai, da ci, de li
wen » when

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: (( yuan yang yu yi dai han bei da xi. ) OR ( guan yuan hui ((de ci) OR (de yi)) tan wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yuan yang yu yi dai han bei da xi. ) or ( guan yuan hui ((de ci) OR (de yi)) tan wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( yuan yang yu yi dai han bei da xi. ) or ( guan yuan hui ((de ci) OR (de yi)) tan wen da xi. ))*.
