In this work, we construct the Lagrangian describing meson-diquark interaction, such that diquark-anti-diquark component as well molecular is introduced when studying ${Z}_{cs}$ states. way, problem solved if only considering ${\overline{D}}^{(*)}{D}_{s}^{(*)}$ components, potentials are suppressed by OZI rule. Through solving Bethe-Salpeter equation, find ${Z}_{cs}(4000{)}^{+}$ can be explained mixture of ${\overline{D}}^{*0}{D}_{s}^{+}$ and ${\overline{A}}_{cs}{S}_{cu}$ components. Besides, for ${\overline{D}}^{*0}{D}_{s}^{*+}/{\overline{A}}_{cs}{A}_{cu}$ system, pole $4208\ifmmode\pm\else\textpm\fi{}13i\text{ }\text{ }\mathrm{MeV}$ on second Riemann sheet predicted, whose mass agrees with ${Z}_{cs}(4220{)}^{+}$ while width much smaller than ${Z}_{cs}(4220{)}^{+}$. Due to large error ${Z}_{cs}(4220{)}^{+}$'s width, further measurements expected. addition, several other poles different spins predicted.
