Perhaps you should try some spelling variations:
reformen teil » reformen bei, reformen beim, reformen des
reformen der » formen der, reform der
david dang » david ian, david mant, david ng
warn you » earn your, can you, when you
wan you » want you, can you, win you
xian li » tian li, kian lia, xiang ji

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: ((wan you) OR (warn you)) xian li ((reformen teil) OR (reformen der)) david dang (hai OR haji) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan you) or (warn you)) xian li ((reformen teil) OR (reformen der)) david dang (hai or haji) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan you) or (warn you)) xian li ((reformen teil) OR (reformen der)) david dang (hai or haji) ;*.
