Perhaps you should try some spelling variations:
qian tan » qian yan, liang tan, qian wang
tan yang » tan ying, tan yong, tao yang
yang jie » yang jin, yang di, yang jui
dan yang » daun yang, wang yang, yang yang
liu gang » liu gangs, liu yang, li gang
gang hai » dang hai, shang hai, eang hay
jing ji » ying jin

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 jie) OR (jing ji)) ((dan yang) OR (tan yang)) liu gang hai ;~.
• Adding a wildcard symbol may retrieve word variants: qian tan ((yang jie) or (jing ji)) ((dan yang) or (tan yang)) liu gang hai ;*.
