I have read the chapter about it by einstein but still can't understand it.
Can anyone kindly explain it to me?

Are you referring to Galilean relativity? To my knowledge, no coordinate system is called Galilean, but the simplest transformation from one observer's viewpoint to another is called the Galilean transformation.

A Galilean system of coordinates in one in which Newton's 3 laws of motion hold in "standard" form.

atyy summed it up, but another way of looking at it is that with respect to a Galilean coordinate system, or inertial reference frame, objects don't change speed or direction without an applied force.
