Perhaps you should try some spelling variations:
reformen bei » reformen beim, reformen teil, reformen der
4 reformen » 1 reformen, 2 reformen, 6 reformen
qian yan » qian jun, qian yi
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, dan yang
liang 4 » liang _, liang li
david g » 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 yan)) liang 4 reformen bei ((david g) OR (david a)) g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) or (nan yan))) or (qian yan)) liang 4 reformen bei ((david g) OR (david a)) g ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (nan yan))) or (qian yan)) liang 4 reformen bei ((david g) OR (david a)) g ;*.
