hua rein » hua ren, hua wei, a rein
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
gun hua » gui hua, tuan hua
yan jiu » pang jiu
long du » long d, long do, long run
wang » wing, wan, lang

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: wang hyoung gun hua rein ((((yan jiu) OR (yang jie))) OR (yang jin)) long du ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung gun hua rein ((((yan jiu) or (yang jie))) or (yang jin)) long du ;*.
