Perhaps you should try some spelling variations:
reformen der » formen der, reform der
reformen de » reformen des, reformen die, reforme de
david hong » david ng
warn you » earn your, can you, when you
xian der » van der, man der, pian del
hong hai » shang hai, zhong tai, dang hai
wan you » want you, can you, win 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) OR (warn you)) xian der ((reformen de) OR (reformen der)) david hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan you) or (warn you)) xian der ((reformen de) OR (reformen der)) david hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan you) or (warn you)) xian der ((reformen de) OR (reformen der)) david hong hai ;*.
