Perhaps you should try some spelling variations:
wei reformen » den reformen, iii reformen, weitere formen
der reformen » der reform
nach david » saah david, macher david
dang hari » dang hai
warn you » earn your, can you, when you
you xian » you liang, you can, you mean
hong ng » hong kong, hong jong, hong hong

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: warn you xian ((wei reformen) OR (der reformen)) nach david ((hong ng) OR (dang hari)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "warn you xian ((wei reformen) OR (der reformen)) nach david ((hong ng) or (dang hari)) ;~".
• Adding a wildcard symbol may retrieve word variants: warn you xian ((wei reformen) OR (der reformen)) nach david ((hong ng) or (dang hari)) ;*.
