With the corrections, we revisit the numerical calculations to the cross sections for the $\\eta_c(nS)$ and the $\\chi_{cJ}(mP)$ states. We argue that the search for $XYZ$ states with even charge conjugation such as $X(3872)$, $X(3940)$, $X(4160)$, and $X(4350)$ recoiled with a photon at BESIII may help clarify the nature of these states.
