In our Letter (Phys. Rev. Lett. vol. 125, 013903 (2020)), we reported topological vortex lasers based on spin-momentum-locked edge modes. We observed that the near field spin and orbital angular momentum has a one-to-one far-field radiation correspondence of circular polarization and orbital angular momentum respectively. Sun et al. in their Comment (arXiv:2009.04700v1), however, argued that we did not perform numerical simulations on the near field information of our experimentally studied topological edge modes, and our mode assignment was mistaken and spoiled the one-to-one correspondence. However, we will show that their arguments are wrong. Furthermore, we will show that the Eqs. (1) and (2) and the phase windings in their Comment are wrong.
