Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
iii reformen » die reformen, iii formen, der reformen
david dang » david ian, david mant
yan wang » yuan wang, yang yang, qian wang
david ng » david g, david a, david _
david n » 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: yan wang yan iii reformen beim ((david dang) OR (((david ng) OR (david n)))) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang yan iii reformen beim ((david dang) or (((david ng) OR (david n)))) hai ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang yan iii reformen beim ((david dang) or (((david ng) OR (david n)))) hai ;*.
