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

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