Perhaps you should try some spelling variations:
dong wei » wang wei, dong di, dong hoi
dann can » dann bin, dan cao, dann hat
wann hat » dann hat, want what, wann ist
yang jui » yang judy, yang yi
when so » when do, when co, when soft
yang xi » yang yi
so min » so ein, so jin, so mi

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