Perhaps you should try some spelling variations:
xxii when » ii when
von dann » von dana, von daten, von denen
yang yue » wang yue, yang yun, yang jui
von dan » von dana, von den, von daf
when so » when do, when co, when soft
yang xi » yang yi, yang jui
so min » so ein, so jin, so mi

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: ing ((von dann) OR (von dan)) xxii when so min ((yang yue) OR (((yang xi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: ing ((von dann) or (von dan)) xxii when so min ((yang yue) or (((yang xi) or (yang di)))) ;*.
