Perhaps you should try some spelling variations:
doing sin » dong sin, doing un, doing von
when jong » when songs, when job
sin dann » sein dann, bin dann, ein dank
jong min » gong min, song min, song ming
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
dann ii » dann bin, daten ii
ii when » xxii when, ii where, ii wesen

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 jong min ((yang jie) OR (((yang di) OR (yang jui)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing sin dann ii when jong min ((yang jie) or (((yang di) or (yang jui)))) ;*.
