Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
qian tan » qian yan, liang tan, qian wang
tan yang » dan yang, tan ying, tao yang
yang jin » yang jie, yang jun, ying jin
tan yong » tan hong, tan kong, tan ying
liu dang » liu yang, liu gang, liu gangs
hai » hadi, haji, hari

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