wang yang » wang yan, wang liang, wang yanling
ming hung » dang hung, fung hung, men hung
when chu » wen chu, when can, when he
ying hua » ming hua, wang hua, ying zhu
yu a » you a, eu a, u a
dong » doing, long, done

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: ((dong sin) OR (wang yang)) ((yu a) OR (a la)) best when chu ((ying hua) OR (ming hung)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (wang yang)) ((yu a) or (a la)) best when chu ((ying hua) or (ming hung)) ;*.
