Perhaps you should try some spelling variations:
doing sin » dong sin, doing un, doing von
when song » when songs, when so, when soft
song ming » song bing, song min, gong min
yang yang » wang yang, wang yan
sin dann » sein dann, bin dann, ein dank
yang yue » wang yue, yang yun, yang jui
dann ii » dann bin, daten ii
ii when » xxii when, ii where, ii wesen
yang yi » yang xi, 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 ming ((((yang yang) OR (yang yue))) OR (((yang yi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing sin dann ii when song ming ((((yang yang) or (yang yue))) or (((yang yi) or (yang di)))) ;*.
