With the parameter range determined by $\\psi (3770) \\to \\phi \\eta$, our estimations of the branching fractions of the light meson decays of $\\psi(3770)$ are consistent with the estimations in the literature. As for $\\psi(3823)$, the partial widths of $K^\\ast \\bar{K}^\\ast$ channel is estimated to be around 200 keV, which is the the predominant light meson decay channel of $\\psi(3823)$.
