Perhaps you should try some spelling variations:
when song » when songs, when so, when soft
dong wei » wang wei, dong di, dong hoi
wei dann » sein dann, wenn dann, wei aun
song min » song ming, gong min, jong min
yang jui » yang judy, yang yi
yang xi » yang yi
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: dong wei dann 4 when song min ((((wang yan) OR (yang jui))) OR (((yang xi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong wei dann 4 when song min ((((wang yan) or (yang jui))) or (((yang xi) or (yang di)))) ;*.
