Perhaps you should try some spelling variations:
yuan yang » yuan fang, yuan yan, dan yang
yuan ying » yuan ming, kuan ying
guan huai » kuan hua, yuan hua
huai hui » hui hui, huan hui, hua hui
di dai » di dati, yi dai, de dai
ji san » ji suan, di san, ci san
de ji » de yi, de li

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) OR (yuan ying)) hui ((di dai) OR (li dai)) tan wen da xi. ) OR ( guan huai hui de ji san wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((yuan yang) or (yuan ying)) hui ((di dai) OR (li dai)) tan wen da xi. ) or ( guan huai hui de ji san wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((yuan yang) or (yuan ying)) hui ((di dai) OR (li dai)) tan wen da xi. ) or ( guan huai hui de ji san wen da xi. ))*.
