We revisit the chiral anomaly in the quantum kinetic theory in the Wigner
function formalism under the background field approximation. Our results show
that the chiral anomaly is actually from the Dirac sea or the vacuum
contribution in the un-normal-ordered Wigner function. We also demonstrate that
this contribution modifies the chiral kinetic equation for antiparticles.
