Perhaps you should try some spelling variations:
wei reformen » der reformen, iii reformen, weitere formen
den reformen » der reformen, von reformen, die reformen
nach david » saah david, macher david
david hong » david ng
you liang » you liangzhi
you xian » you can, you mean
hong ghi » zhong zhi, hong g, hong 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: wan ((you xian) OR (you liang)) ((wei reformen) OR (den reformen)) nach david hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((you xian) or (you liang)) ((wei reformen) OR (den reformen)) nach david hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((you xian) or (you liang)) ((wei reformen) OR (den reformen)) nach david hong ghi ;*.
