We adopt the quark pair creation model to investigate the light meson emissions of several charmonium-like states.The quark pair creation model is applied to four-body systems,and we calculate the pion/kaon emissions of X(4700),Zc(4430),Y(4230),Y(4360),Y(4390),and Y(4660)within compact tetraquark configurations.We find that the pion/kaon decay widths of X(4700)and Zc(4430)are relatively small,whereas the partial decay widths of the resonances Y(4230),Y(4360),Y(4390),and Y(4660)are significant.We expect that our exploration of these de-cay behaviors will provide useful information for future experimental searches and theoretical interpretations.
