Perhaps you should try some spelling variations:
dank hari » bank hard
dong cao » dong xiao, dan cao, dong nan
dong bin » dong di, dann bin
test how » west how, tested how, trust how
ein dank » mein dank, sein dann, bin dann
how ein » now eine
y la » a la, _ la
u a » up a, eu a, uk a

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) OR (((dong sin) OR (dong bin)))) ((u a) OR (y la)) test how ein dank hari ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) OR (((dong sin) OR (dong bin)))) ((u a) OR (y la)) test how ein dank hari ;*.
