Abstract
Abstract In this study, we explore the hadronic coupling constants , , and of the exotic states within the pictures of both the tetraquark and molecular states with the tentative assignments based on rigorous quark-hadron duality. Subsequently, we obtain the total widths and , which are consistent with experimental values from the BESIII collaboration, , and LHCb collaboration, , respectively, and support assigning and as the hidden-charm tetraquark and molecular states with , respectively.
