Perhaps you should try some spelling variations:
banken bank » banking bank, bank bank, banken basen
die banken » der banken
bank doing » bank adding, bank moving, bank working
yang yig » yang yang, yang jing, yang jie
yang yun » yang jun, tang yun, yang yue
doing a » doing _
yang yi » yang jui
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: die banken bank doing a ((yang yig) OR (((yang yi) OR (yang di)))) ((yang yun) OR (yang xi)) ;~.
• Adding a wildcard symbol may retrieve word variants: die banken bank doing a ((yang yig) or (((yang yi) or (yang di)))) ((yang yun) or (yang xi)) ;*.
