rein yan » ren yan
long shu » cong shu, tong shui
yan jiu » yang jie, yang jin, pang jiu
long do » long d, longer do, long ago
long du » long d, long run, long did
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 do) OR (long du)))) ;~.
• 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 do) OR (long du)))) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) hyoung gun a rein yan jiu ((long shu) or (((long do) OR (long du)))) ;*.
