Perhaps you should try some spelling variations:
wei reformen » den reformen, iii reformen, weitere formen
der reformen » der reform
bulan david » bulman david, balan david, blanc david
zhong tai » hong tan, zhong zhi
you xian » you liang, you can, you mean
hong hai » shang hai, dang hai, hong tan
wan you » want you, warn you, can you

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 you xian ((wei reformen) OR (der reformen)) bulan david ((zhong tai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan you xian ((wei reformen) or (der reformen)) bulan david ((zhong tai) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan you xian ((wei reformen) or (der reformen)) bulan david ((zhong tai) OR (hong hai)) ;*.
