Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
done ist » done so, code ist, done get
has done » has gone, has one, has money
yang jie » yang jin, yang xi, yang jun
yang jui » yang judy, yang xi
ist has » ist das, ist halt, past has
yang yi » yang xi

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: done ist has done when ((((yang jie) OR (wang yang))) OR (yang di)) ((yang jui) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: done ist has done when ((((yang jie) or (wang yang))) or (yang di)) ((yang jui) or (yang yi)) ;*.
