Perhaps you should try some spelling variations:
yuan yong » yuan ying, huan yong, kuan yong
yong hui » ong hui, wong hui, yong hoi
dai tan » dai tang, dai tian, dai han
han hui » chan hui, huan hui, han hu
hui di » hui ji, hui de, hui li
di dai » di dati, li dai, yi dai
ci san » chi san, di san, ji san
de ci » de cai, de yi, da ci

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