Perhaps you should try some spelling variations:
when songs » when sounds, den songs
doing sin » dong sin, doing un, doing von
when song » when so, when soft, when some
sin dann » sein dann, bin dann, ein dank
yang yun » yang jun, tang yun, yang yue
yang jui » yang judy, yang di, yang yi
dann ii » dann bin, daten ii
yang xi » yang di, 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: doing sin dann ii ((when song) OR (when songs)) min ((yang yun) OR (((yang jui) OR (yang xi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doing sin dann ii ((when song) OR (when songs)) min ((yang yun) or (((yang jui) or (yang xi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: doing sin dann ii ((when song) OR (when songs)) min ((yang yun) or (((yang jui) or (yang xi)))) ;*.
