Perhaps you should try some spelling variations:
when adding » why adding, when handling, when adapting
smart when » start when, art when
der klang » der klange, den klang, des klangs
klang die » klang der, klang iii, klaue die
die smart » der smart
dong skin » dong sin, dof skin
dong bin » dong sin, dong di, dann bin
gang » lang, wang, yang

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: gang der klang die smart when adding ((dong bin) OR (dong skin)) ;~.
• Adding a wildcard symbol may retrieve word variants: gang der klang die smart when adding ((dong bin) or (dong skin)) ;*.
