First notebook entry: Introducing myself

My frist first name (or: my given name) is Mahire ,I'm a student,I'm living ShangHai at now.

We do not use at with now.  We can say at present, which has the same meaning as now, but now usually stands alone.  Both of them mean at this moment.. 

You might see the expression, for now, which means for the present.  It's used this way:

That's all for now. (=That's all for the present.  Maybe more later.)

I may want to visit more countries in the future but for now the only place I want to go is China.
