Perhaps you should try some spelling variations:
reformen a » reformen _, reformen 6, reformen f
reformen 2 » reformen _, reformen im, formen 2
zhang der » zwang der, anhang der, zugang der
zhang zhi » zhong zhi, wang zhi, zhang wei
zhong tai » hong tan, hong hai, zhong zhi
do zhang » ceo zhang, hao zhang, _ zhang

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: when do zhang der ((reformen a) OR (reformen 2)) davis ((zhang zhi) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "when do zhang der ((reformen a) OR (reformen 2)) davis ((zhang zhi) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: when do zhang der ((reformen a) OR (reformen 2)) davis ((zhang zhi) or (zhong tai)) ;*.
