Perhaps you should try some spelling variations:
wei reformen » der reformen, den reformen, iii reformen
nach david » saah david, macher david
warn you » earn your, can you, when you
you xian » you liang, you can, you mean
xian wei » xiang wei, liang wei, han wei
hong ng » hong kong, hong jong, hong hong
hai » hadi, haji, thai

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