Perhaps you should try some spelling variations:
die banken » der banken
banken den » banken wenn, banken bei, banken die
den mainz » en main, den mann
mainz die » main die
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
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 banken den mainz die ((yang jin) OR (((shang jin) OR (yang xi)))) ((wong yue) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: die banken den mainz die ((yang jin) or (((shang jin) or (yang xi)))) ((wong yue) or (yang di)) ;*.
