\begin{document}$ Z_c(3900/3885) $\end{document} and \begin{document}$ Z_{cs}(3985/4000) $\end{document}, we tentatively assign \begin{document}$ Z_c(4020/4025) $\end{document} as the \begin{document}$ A{\bar{A}} $\end{document}-type hidden-charm tetraquark state with \begin{document}$ J^{PC}=1^{+-} $\end{document}, where A denotes the axialvector diquark states, and explore \begin{document}$ A{\bar{A}} $\end{document}-type tetraquark states without strange, with strange, and with hidden-strange via QCD sum rules in a consistent manner. We then explore the hadronic coupling constants in the two-body strong decays of tetraquark states without and with strange via QCD sum rules based on rigorous quark-hadron duality and acquire partial and total decay widths. The present calculations support assigning \begin{document}$ Z_c(4020/4025) $\end{document} as the \begin{document}$ A{\bar{A}} $\end{document}-type tetraquark state with \begin{document}$ J^{PC}=1^{+-} $\end{document}, while the predictions for its strange cousin \begin{document}$ Z_{cs} $\end{document} state can be confronted with experimental data in the future."> Strange cousin of <i>Z</i><sub><i>c</i></sub>(4020/4025) as a tetraquark state -
