Perhaps you should try some spelling variations:
den reformen » der reformen, von reformen, die reformen
reformen bei » reformen beim, reformen teil, reformen der
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
zhang den » zhang fan, zhang wei, zhang yan
bei david » beni davide, levi david, de david
qian yi » qian yan

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: ((((yang yang) OR (wang yang))) OR (qian yi)) zhang den reformen bei david a w ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (wang yang))) or (qian yi)) zhang den reformen bei david a w ;*.
