hyoung gun » young eun
hua rein » hua ren, hua wei, a rein
pang jiu » pang jun, yang jie, pan ji
yang jin » yang jie, yang jun, ying jin
gun hua » gui hua, tuan hua
yan jiu » yang jie
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 (pang jiu))) OR (yang jin)) long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung gun hua rein ((((yan jiu) OR (pang jiu))) or (yang jin)) long du ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung gun hua rein ((((yan jiu) OR (pang jiu))) or (yang jin)) long du ;*.
