Perhaps you should try some spelling variations:
when gong » when songs, when good, when goal
dong wei » wang wei, dong di, dong hoi
wei dann » sein dann, wenn dann, wei aun
dann hat » wann hat, dang hai, man hat
hat when » what when, data when, art when
gong min » jong min, song min, gong meng
yang jui » yang judy, yang yi
yang xi » yang yi

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 hat when gong min ((yang xi) OR (((yang di) OR (yang jui)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong wei dann hat when gong min ((yang xi) or (((yang di) or (yang jui)))) ;*.
