Perhaps you should try some spelling variations:
sein dann » sein kann, sein das, bin dann
when song » when songs, when so, when soft
sin dann » bin dann, ein dank, sin cain
song min » song ming, gong min, jong min
yang yun » yang jun, tang yun, yang yue
yang jui » yang judy, yang di, yang yi
ii when » xxii when, ii where, ii wesen
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) OR (sein dann)) ii when song 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) OR (sein dann)) ii when song min ((yang yun) or (((yang jui) or (yang xi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: doing ((sin dann) OR (sein dann)) ii when song min ((yang yun) or (((yang jui) or (yang xi)))) ;*.
