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