Perhaps you should try some spelling variations:
mein dank » ein dank, sein dann
dank yuan » fang yuan, yan yuan
yuan chen » yuan cheng, yun chen, sudan chen
chen ping » chen rong, chen yang, chen wang
ping ji » ping jia, jing ji, ping yi
wang he » wang zhi, wang wei, wang hui
yang yi » yang di, yang xi, 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 yuan chen ping ji ((((wang he) OR (wang hua))) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) mein dank yuan chen ping ji ((((wang he) or (wang hua))) or (yang yi)) ;*.
