Perhaps you should try some spelling variations:
den reformen » von reformen, die reformen, den referaten
der reformen » der reform
you liang » you xian, you liangzhi
zhong zhi » zhang zhi, zhong tai
hong ghi » hong g, hong hai
wan you » want you, warn you, can you
bulman » bulan

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 liang ((der reformen) OR (den reformen)) bulman david ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan you liang ((der reformen) or (den reformen)) bulman david ((hong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan you liang ((der reformen) or (den reformen)) bulman david ((hong ghi) OR (zhong zhi)) ;*.
