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

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 OR lang) hyoung gun hua rein ((yan jiu) OR (((yang jin) OR (yang jun)))) long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) hyoung gun hua rein ((yan jiu) or (((yang jin) OR (yang jun)))) long du ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) hyoung gun hua rein ((yan jiu) or (((yang jin) OR (yang jun)))) long du ;*.
