Perhaps you should try some spelling variations:
when gong » when songs, when good, when goal
doing un » doing und, doing our, doing von
gong min » jong min, song min, gong meng
yang jin » yang jie, yang jun, ying jin
un dann » und dann, um dann, bin dann
yang yi » yang jui
yang xi » yang jui
dann 4 » dann _, dann 4.3
4 when » 3 when

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 4 when gong min ((((yang jin) OR (yang yi))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing un dann 4 when gong min ((((yang jin) or (yang yi))) or (((yang di) or (yang xi)))) ;*.
