what to do after I received I-824 approval notice

[9789]

Hi everyone
I really need help from experts.
I got married and have a child before I got my green card in 2011.
My wife and my child are in China.
So I filed consulate process for their immigration visa
I filed I-824 form and it was approved.
I do not know what to do next.
It seems like I need to file another form to contact national visa center.
I do not know what to do.
please help me out
