Perhaps you should try some spelling variations:
yuan yong » yuan ying, huan yong, kuan yong
yuan yuan » guan yuan, yuan yan, yuan yu
yuan hua » kuan hua, yuan qu
bai tan » bai yan, ai tan, bi tan
hoi yi » choi yi, hui yi, hii yi
hai yi » hui yi, hai zi, dai yi
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 yong ((hoi yi) OR (hai yi)) bai tan wen da xi. ) OR ( yuan yuan hua de di san wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yuan yong ((hoi yi) OR (hai yi)) bai tan wen da xi. ) or ( yuan yuan hua de di san wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( yuan yong ((hoi yi) OR (hai yi)) bai tan wen da xi. ) or ( yuan yuan hua de di san wen da xi. ))*.
