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