Perhaps you should try some spelling variations:
doing un » doing und, doing our, doing von
dann bin » dong bin
bin when » win when, can when, bin we
yang yun » yang jun, tang yun, yang yue
un dann » und dann, um dann, bin dann
when so » when do, when co, when soft
so bing » so big, so fing, so ging
yang yi » yang jui
yang xi » 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: doing un dann bin when so bing ((yang yun) OR (((yang di) OR (((yang yi) OR (yang xi)))))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing un dann bin when so bing ((yang yun) or (((yang di) or (((yang yi) or (yang xi)))))) ;*.
