Perhaps you should try some spelling variations:
wang yang » wang liang, wang yanling
qian yan » qian jun, qian yi
yan ying » fan ying, ran ying, tan ying
ying jin » yang jin, jing ji, yang jie
yao yang » yang yang
liu gang » liu gangs, liu yang, li gang
gang hai » dang hai, shang hai, eang hay

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