Perhaps you should try some spelling variations:
wang yidan » wang yan
dong ping » dong sin, dong bin, dong jung
ping dank » ein dank, king dan, ping wang
dank done » want done
yang jie » yang jin, yang jui, yang yi
yang yun » yang jun, tang yun, yang yue
yang xi » yang yi, yang jui

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: dong ping dank done when ((yang xi) OR (yang jie)) ((((yang yun) OR (wang yidan))) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong ping dank done when ((yang xi) or (yang jie)) ((((yang yun) or (wang yidan))) or (yang di)) ;*.
