By tailoring optical gain and loss in integrated photonic structures, $\\mathcal{PT}$ symmetric non-Hermitian photonics has found applications in many fields ranging from single mode lasing to novel topological matters. Here we propose a new paradigm towards non-Hermitian photonics based on the charge-parity ($\\mathcal{CP}$) symmetry that has the potential to control the flow of light in an unprecedented way.
