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