Perhaps you should try some spelling variations:
den reformen » der reformen, von reformen, die reformen
reformen a » reformen _, reformen 2, reformen 6
zhang den » zhang fan, zhang wei, zhang yan
zhong zhi » zhang zhi, hong ghi
zhong tai » hong tan, hong hai
do zhang » ceo zhang, hao zhang, _ zhang
a davis » _ davis, m davis, a david

You may be able to get more results by adjusting your search query.

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