Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
die reformen » die reform, die formen, der reformen
yang liang » wang liang, yan liang, yang yang
beim david » kim david
you liang » you xian, you liangzhi
david ng » david g, david n, david a
ng g » g g, n g, ng _

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