Perhaps you should try some spelling variations:
wang liang » wang yang
liu gangs » liu gang, liu yang
gangs hai » dang hai
qian yan » qian jun, qian yi
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
fan ying » fan xing, ran ying, tan ying

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