Perhaps you should try some spelling variations:
one fallt » one fast
dann doch » kann doch, dann auch, dann nich
doch when » do when, done when, rich when
dong ping » dong sin, dong bin, dong jung
pang jun » yang jui
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: one fallt dann doch when ((((yang xi) OR (dong ping))) OR (pang jun)) ((yang yun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one fallt dann doch when ((((yang xi) or (dong ping))) or (pang jun)) ((yang yun) or (yang di)) ;*.
