Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
long shu » cong shu, tong shui
yan hua » tan hua, ya hua, wang hua
hua see » chua tee, chua yee
yan jiu » yang jie, yang jin, 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 yan hua see yan jiu ((long shu) OR (long du)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan hua see yan jiu ((long shu) or (long du)) ;*.
