Perhaps you should try some spelling variations:
die banken » der banken
banken can » banking can, bank can, banken c
donor chen » don chen
can donor » can donors, a donor
wang jing » wang ning, wang liang, wang yang
yang jui » yang judy, yang yi
yang yun » yang jun, tang yun, yang yue
yang xi » yang yi

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 banken can donor chen ((wang jing) OR (((yang jui) OR (yang di)))) ((yang yun) OR (yang xi)) ;~.
• Adding a wildcard symbol may retrieve word variants: die banken can donor chen ((wang jing) or (((yang jui) or (yang di)))) ((yang yun) or (yang xi)) ;*.
