Perhaps you should try some spelling variations:
when song » when songs, when so, when soft
wang wei » zhang wei, wang zhi
wei dann » sein dann, wenn dann, wei aun
song min » song ming, gong min, jong min
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang yi
yang xi » yang yi
dann i » dann _, ann i, dann bin
i when » ii when, 3 when, 4 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: wang wei dann i when song min ((yang jun) OR (((((yang xi) OR (yang jui))) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang wei dann i when song min ((yang jun) or (((((yang xi) or (yang jui))) or (yang di)))) ;*.
