The ordinary and quantum Hall effects with fixed carrier types, electron or hole, exhibit well-defined chirality under external magnetic fields, but the analogous chirality of the quantum anomalous Hall effect (QAHE) remains little explored. Here, for the electronic structures of intrinsic QAHE syst...
