Inspired by the recent observation of the charged charmoniumlike structure , we explore the 
decay through the initial-single-pion-emission mechanism, where the 
interaction is studied by the ladder approximation, including the non-interacting case. Our calculation of the differential decay width for indicates that a charged enhancement structure around 
appears in the invariant mass spectrum for this process, which might correspond to the newly observed structure.
