Perhaps you should try some spelling variations:
reformen de » reformen der, reformen des, reformen die
david dang » david ian, david mant, david ng
qiang niu » qiang li
de david » die david, wade david, dawe david
wan you » want you, warn you, can 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 ((qian yi) OR (qiang niu)) reformen de david dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan you ((qian yi) or (qiang niu)) reformen de david dang hai ;*.
