Perhaps you should try some spelling variations:
reformen alan » reform alan, reform plan, reformen a
reformen von » formen von, reform von, referaten von
david young » david loundy
xiang wei » liang wei, zhang wei, fang wei
wang wei » zhang wei, wang zhi
wan you » want you, warn you, can you
choi » chi, cho

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 ((wang wei) OR (xiang wei)) ((reformen alan) OR (reformen von)) david young choi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan you ((wang wei) or (xiang wei)) ((reformen alan) OR (reformen von)) david young choi ;~".
• Adding a wildcard symbol may retrieve word variants: wan you ((wang wei) or (xiang wei)) ((reformen alan) OR (reformen von)) david young choi ;*.
