Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
beim david » kim david
david dang » david ian, david mant, david ng
zwang iii » zugang iii, klang iii
klang die » klang der, klang iii, klaue die
yan wang » yuan wang, yang yang, qian wang
yang iii » klang iii, yang zili, 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 ((((yang iii) OR (zwang iii))) OR (klang die)) reformen beim david dang (hai OR hadi) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang ((((yang iii) OR (zwang iii))) or (klang die)) reformen beim david dang (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang ((((yang iii) OR (zwang iii))) or (klang die)) reformen beim david dang (hai or hadi) ;*.
