Perhaps you should try some spelling variations:
reformen teil » reformen bei, reformen beim, reformen der
4 reformen » 1 reformen, 2 reformen, 6 reformen
teil david » weil david, fell david
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan
qian yi » qian yan
liang 4 » liang _, liang li
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 yan) OR (nan yan))) OR (qian yi)) liang 4 reformen teil david g g ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (nan yan))) or (qian yi)) liang 4 reformen teil david g g ;*.
