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