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) $ , $ X(4700) $ , $ X(4700) $ , $ X(4700) $ , $ X(4700) $ , and $ X(4700) $ within compact tetraquark configurations. We find that the pion/kaon decay widths of $ X(4700) $ and $ X(4700) $ are relatively small, whereas the partial decay widths of the resonances $ X(4700) $ , $ X(4700) $ , $ X(4700) $ , and $ X(4700) $ are significant. We expect that our exploration of these decay behaviors will provide useful information for future experimental searches and theoretical interpretations.
