Perhaps you should try some spelling variations:
reformen bei » reformen beim, reformen teil, reformen der
wei reformen » der reformen, den reformen, iii reformen
zhang wei » zhen wei
bei david » beni davide, levi david, de david
wan yan » nan yan, wai yan, wang yang
qian yi » qian yan
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: ((((wan yan) OR (wang yan))) OR (qian yi)) zhang wei reformen bei david n w ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (wang yan))) or (qian yi)) zhang wei reformen bei david n w ;*.
