tan yuan » tan yan, tan yen, tan yung
yuan yan » yuan yang, yuan yuan, yuan ying
bai tan » bai yan, ai tan, bi tan
hoi yi » choi yi, hui yi, hai 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: (( ((huan yong) OR (wan yong)) hoi yi bai tan wen da xi. ) OR ( ((tan 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 ( ((tan yuan) or (yuan yan)) hua de di san wen da xi. ))*.
