Perhaps you should try some spelling variations:
qian wang » yiqian wang, qian rong, qian yan
wang yong » wang yang, wang hyoung, wang yan
tan yang » dan yang, tan ying, tan yong
yao yang » yang yang
liu gang » liu gangs, liu yang, li gang
gang hai » dang hai, shang hai, eang hay
yong ji » yang jie, yang jin, ying jin

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: qian wang yong ji ((tan yang) OR (yao yang)) liu gang hai ;~.
• Adding a wildcard symbol may retrieve word variants: qian wang yong ji ((tan yang) or (yao yang)) liu gang hai ;*.
