Perhaps you should try some spelling variations:
hyoung gun » young eun
rein yan » ren yan
long shu » cong shu, tong shui
yan jiu » yang jie, yang jin, pang jiu
long du » long d, long run, long did
long do » long d, longer do, long ago
a rein » a reine, a reit, a region
gun a » run a, fun a, gun 2
wang » wing, 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 OR wan) hyoung gun a rein yan jiu ((((long shu) OR (long du))) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) hyoung gun a rein yan jiu ((((long shu) OR (long du))) or (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) hyoung gun a rein yan jiu ((((long shu) OR (long du))) or (long do)) ;*.
