In this paper, we study the existence and the limit behavior of normalized solutions for the Chern–Simons–Schrödinger equations with mixed Choquard-type nonlinearities and $\frac{\alpha }{2}+2<q<p<+\mathrm{\infty }$. Moreover, we also get the relationship between the minimizer and the ground state solution under the Pohožaev–Nehari manifold of the Chern–Simons–Schrödinger equations.
