Perhaps you should try some spelling variations:
reformen kim » reformen im, reformen beim, reformen ii
reformen die » reformen der, reforme de, reformen des
david dang » david ian, david mant, david ng
zwang iii » zugang iii, klang iii
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)) ((reformen kim) OR (reformen die)) 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)) ((reformen kim) OR (reformen die)) david dang (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang ((yang iii) or (zwang iii)) ((reformen kim) OR (reformen die)) david dang (hai or hadi) ;*.
