Perhaps you should try some spelling variations:
iii reformen » die reformen, iii formen, der reformen
reformen kim » reformen im, reformen beim, reformen die
wang zwang » wang liang, wang zheng, wang zaibang
david dang » david mant, david ng
wang yang » wang yan, wang liang, wang yanling
david ian » david a, david n

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