  We have constructed a non-Hermitian two-level system (a PT -symmetric system)
in dissipative environments, and investigated the quantum coherence in the
non-Hermitian two-level system. Our results show that, quantum coherence can be
created by PT -symmetric systems, even if the initial state of the twolevel
system is incoherent state. Even though two-level system is interacted with
dissipative environments, the quantum coherence exhibits a long-lived revival,
and can be protected. We find that the two-level system can obtain more
coherence with the coupling strength {\Omega} increases. And we should point
out that the PT -symmetric system can be regarded as a good candidate system
for creation of the long-lived quantum coherence in dissipative environments.
