Perhaps you should try some spelling variations:
reformen teil » reformen bei, reformen beim, reformen der
die reformen » die reform, die formen, der reformen
you qiang » you liang, you xian
qiang die » klang die, qiang li, qiang niu
david ian » david a
warn you » earn your, can you, when you
david n » david a, david _, david k

You may be able to get more results by adjusting your search query.

• Adding a wildcard symbol may retrieve word variants: warn you qiang die reformen teil ((david ian) or (david n)) hai ;*.
