Perhaps you should try some spelling variations:
iii reformen » die reformen, iii formen, der reformen
reformen bei » reformen beim, reformen teil, reformen der
wang yang » wang yan, wang liang, wang yanling
you liang » you xian, you liangzhi
david ng » david n, david a, david _
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 ((wang yang) OR (you liang)) iii reformen bei ((david ng) OR (david g)) g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((wang yang) or (you liang)) iii reformen bei ((david ng) OR (david g)) g ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((wang yang) or (you liang)) iii reformen bei ((david ng) OR (david g)) g ;*.
