It means that two newly reported charmoniumlike states are not genuine resonances, according to which we can naturally explain why two well-established charmonia $\\psi(4160)$ and $\\psi(4415)$ are missing in the cross sections of $e^+e^- \\to \\pi^+ \\pi^- J/\\psi$ and $\\pi^+ \\pi^- h_c$ simultaneously.
