In this work, we explore the hadronic coupling constants $G_{ZJ/\psi K}$,$G_{Z\eta_c K^*}$, $G_{ZD^* \bar{D}_s}$ of the exotic states$Z_{cs}(3985/4000)$ both in the pictures of the tetraquark states and molecularstates with the tentative assignments $J^{PC}=1^{+-}$ based on the rigorousquark-hadron duality. Then we obtain the total widths $\Gamma_{Z_{cs}}^T=15.31\pm 2.06\,\rm{MeV}$ and $\Gamma_{Z_{cs}}^M=83.51\pm21.09\,\rm{MeV}$,which are consistent with the experimental data$13.8^{+8.1}_{-5.2}\pm4.9\,\rm{MeV}$ from the BESIII collaboration and $131 \pm15 \pm 26\,\rm{MeV}$ from the LHCb collaboration, respectively, and supportassigning the $Z_{cs}(3985)$ and $Z_{cs}(4000)$ to be the hidden-charmtetraquark state and molecular state with the $J^{PC}=1^{+-}$, respectively.
