Perhaps you should try some spelling variations:
yuan yang » yuan ying, yuan fang, dan yang
guan phua » guan hua, guan xihua, guan chuah
yuan yan » yuan yuan, yuan ying, yuan fang
phua hui » chua hui, phua mui, phua chai
dai tan » dai tang, dai tian, dai han
yi dai » li dai, yi da, yi bai
de di » de yi, de li, de ji

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