Perhaps you should try some spelling variations:
reformen teil » reformen beim, reformen der, reformen des
reformen bei » reformen beim, reformen der, reformen des
david dang » david ian, david mant, david ng
wang yang » wang yan, wang liang, wang yanling
yan wang » yuan wang, yang yang, qian wang
yang iii » klang iii, yang zili, zwang iii

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: yan wang yang iii ((reformen bei) OR (reformen teil)) ((david dang) OR (david a)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang yang iii ((reformen bei) OR (reformen teil)) ((david dang) or (david a)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang yang iii ((reformen bei) OR (reformen teil)) ((david dang) or (david a)) hai ;*.
