　　We demonstrate a photonic topological insulator (PTI) in an atomic vapor ensemble,by utilizing the multi-beam interference method.In the method,thethree-beam (coupling fields) interference results in a honeycomb lattice pattern which dresses and splits the dressed energy level periodically,so that thecorresponding susceptibilities will be modulated periodically due to dressing effect of the honeycomb lattice interference pattern.
