Perhaps you should try some spelling variations:
mein dank » ein dank, sein dann
yulu chen » yu chen
chen ping » chen rong, chen yang, chen wang
wang yue » wong yue, wang hua, wang yan
ping ji » ping jia, jing ji, ping yi
hong yu » wong yue
yang xi » yang di, yang yi, yang jui

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: (dong OR doing) mein dank yulu chen ping ji ((((wang yue) OR (hong yu))) OR (yang xi)) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) mein dank yulu chen ping ji ((((wang yue) or (hong yu))) or (yang xi)) ;*.
