Parity violation found in the Cosmic Microwave Background (CMB) radiation isa crucial clue for the non-standard cosmological model or the possiblecontamination of various foreground residuals and/or calibration of the CMBdata sets. In this paper, we study the directional properties of the CMB parityasymmetry by excluding the $m=0$ modes in the definition of parity parameters.We find that the preferred directions of the parity parameters coincide withthe CMB kinematic dipole, which implies that the CMB parity asymmetry may beconnected with the possible contamination of the residual dipole component. Wealso find that such tendency is not only localized at $l=2,3$, but in theextended multipole ranges up to $l\sim 22$.

Is the CMB asymmetry due to the kinematic dipole?
