Perhaps you should try some spelling variations:
card donor » aid donor, can donor
donor chen » don chen
wang yang » wang yan, wang liang, wang yanling
die bank » die banken
yang jie » yang jin, yang jui, yang yi
yang yun » yang jun, tang yun, yang yue
yang xi » 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: die bank card donor chen ((wang yang) OR (((yang jie) OR (yang di)))) ((yang yun) OR (yang xi)) ;~.
• Adding a wildcard symbol may retrieve word variants: die bank card donor chen ((wang yang) or (((yang jie) or (yang di)))) ((yang yun) or (yang xi)) ;*.
