  In this work we show that the chiral magnetic effect (CME) could cause the
quark-gluon plasma (QGP) approximately forming three layers along the strong
magnetic field characterised by different compositions of quark chemical
potentials. This phenomenon may bring new observable outcomes, for example
different layers would have different CEPs and the $u,d$ quarks would have
different critical end points (CEPs). Since the $s$ quark would make the up and
the down layers have some 'asymmetry' on chemical potentials, there is the
possibility that at some special conditions one flavor of $u,d$ quarks lies at
CEP in one layer but another flavor dose not in any layer. These results may be
helpful in testing the existence of CME.
