Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
tong shui » tong hui, cong shu, gong hui
chua tee » chua yee
long shu » cong shu
hua see » 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) OR (chua tee)) yan jiu ((((long shu) OR (tong shui))) OR (long du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung yan ((hua see) OR (chua tee)) yan jiu ((((long shu) or (tong shui))) or (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan ((hua see) OR (chua tee)) yan jiu ((((long shu) or (tong shui))) or (long du)) ;*.
