Corona SDK offset not good

I just started using Corona SDK. And learning how to make apps with it. For example i am using:

local myRectangle = display.newRect( 0, 0, 150, 50 )
myRectangle.strokeWidth = 3
myRectangle:setFillColor( 0.7 )
myRectangle:setStrokeColor( 1, 0, 0 )

When i use this it will look like this on my phone

enter image description here

When i am using this code:

local myRectangle = display.newRect( 77, 27, 150, 50 )
myRectangle.strokeWidth = 3
myRectangle:setFillColor( 0.7 )
myRectangle:setStrokeColor( 1, 0, 0 )

Then it will looks like this on my phone:

enter image description here

It looks like the offset is not good. Does anybody know how to fix this problem?

At default, anchor point is in center of object. So if you set

myRectangle.x = 0 
myRectangle.y = 0

center of the object will be at 0, 0. To change it, set anchors to 0, 0 (top left)

myRectangle.anchorX = 0
myRectangle.anchorY = 0

Whenever I make objects, I always set the x and y to 0 in the actual API. Then I do this after I create my object:

myRectangle.x = display.contentWidth/2
myRectangle.y = display.contentHeight/2

Hopefully this helps.
