Gnu radio has connect api to connect the flow graph,so it
connect uni-direction/bi-directionly ? if it is unidirectional then can
we
change it to bidirection ?

connections are unidirectional flows of data.

You could however create two connections in opposing directions. Now a
traditional gnuradio block will see this a circular loop and you cant do
this.

But, I suspect you are doing something with passing messages between
blocks. You may want to check out gr extras. This will allow two blocks
to bidirectionally communicate:
