Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
den reformen » der reformen, von reformen, die reformen
david ian » david a, david n
yan yang » yang yang, yao yang, dan yang
yang den » yang dean, gang der, yang di
david g » david a, david _, david k
wang » wing, wan, lang

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: wang yan yang den reformen beim ((david ian) OR (david g)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan yang den reformen beim ((david ian) or (david g)) hai ;*.
