Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
qian tan » qian yan, liang tan, qian wang
tan ying » fan ying, ran ying, tan yong
ying jin » yang jin, jing ji, yang jie
tan yang » dan yang, tan yong, tao 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.

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