Perhaps you should try some spelling variations:
kindern doing » kinder doing, kindern dinge, kind doing
kann kindern » kann minderung, von kindern, und kindern
wang yang » wang yan, wang liang, wang yanling
doing von » doing un, ing von
yang tan » yang fan, yang yang, liang tan
ruan jin » ruan ji, huan jie
jin kann » jin kang, sein kann, wie kann
dean » dewan, jean, den

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: wang ((((yang tan) OR (wang yang))) OR (yang dean)) ruan jin kann kindern doing von ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((yang tan) or (wang yang))) or (yang dean)) ruan jin kann kindern doing von ;*.
