Perhaps you should try some spelling variations:
sein dann » sein kann, sein das, bin dann
when gong » when songs, when good, when goal
gong min » jong min, song min, gong meng
yang yun » yang jun, tang yun, yang yue
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 sein dann ii when gong min ((yang yun) OR (((yang jui) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing sein dann ii when gong min ((yang yun) or (((yang jui) or (yang di)))) ;*.
