Perhaps you should try some spelling variations:
reformen im » reformen _, formen im, reformen der
david dang » david ian, david mant, david ng
qiang niu » qiang li
im david » kim david, lam david, die david
wan you » want you, warn you, win you
qian yi » qian yan
hai » hadi, haji, hari

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) OR (can you)) ((qian yi) OR (qiang niu)) reformen im david dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan you) OR (can you)) ((qian yi) or (qiang niu)) reformen im david dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan you) OR (can you)) ((qian yi) or (qiang niu)) reformen im david dang hai ;*.
