How can I remove the notification bar?

[bj097]

I need notification of new messages.
but I find that when I am doing something else and the notification bar comes up at the top, I am unable to delete it but it just stays there for a long time....

Is it possible for the notification bar goes away more quickly?

but why it cannot be removed quickly?

Have you tried swiping up on the notification?
