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

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 ran) OR (qian wang)) yang jin ((((tan yang) OR (tan yong))) OR (tao yang)) liu gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((qian ran) or (qian wang)) yang jin ((((tan yang) OR (tan yong))) or (tao yang)) liu gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((qian ran) or (qian wang)) yang jin ((((tan yang) OR (tan yong))) or (tao yang)) liu gang hai ;*.
