Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
yang hua » wang hua, yang hui, ying hua
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
long shu » cong shu, tong shui, long du
yan jiu » pang jiu

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 yong yang hua (rein OR rain) ((yan jiu) OR (((yang jin) OR (yang jie)))) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang hua (rein or rain) ((yan jiu) or (((yang jin) OR (yang jie)))) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang hua (rein or rain) ((yan jiu) or (((yang jin) OR (yang jie)))) long shu ;*.
