Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
iii reformen » die reformen, iii formen, der reformen
yang zugang » yang guang
wan yang » wang yang, dan yang, tan yang
david ng » david n, david a, david _
david g » david a, david _, david k

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: wan yang zugang iii reformen beim ((david ng) OR (david g)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan yang zugang iii reformen beim ((david ng) or (david g)) hai ;*.
