Perhaps you should try some spelling variations:
formen die » formel die, former die, reformen die
ii formen » iii formen, ii normen, die formen
klang ii » klang iii, klang die, klang 3
david ma » david mant, david ian, david _
david m » david _, david k, david g
qian » ian, kian, jian
rong » long, hong, pong

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: qian rong klang ii formen die ((((david ma) OR (david m))) OR (david a)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian rong klang ii formen die ((((david ma) OR (david m))) or (david a)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: qian rong klang ii formen die ((((david ma) OR (david m))) or (david a)) hai ;*.
