Perhaps you should try some spelling variations:
wei reformen » der reformen, den reformen, iii reformen
reformen jan » reformen von, reformen a, reformen nach
you liang » you liangzhi
jan david » juan david, sahn david, alan david
you xian » you can, you mean
hong g » hong ng, hong w, hong 7
hai » hadi, haji, hari

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