Perhaps you should try some spelling variations:
reformen juan » reformen und, reformen a, reformen aus
reformen von » formen von, reform von, referaten von
want you » what you
you xian » you liang, you can, you mean
xian wei » xiang wei, liang wei, han wei
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai

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