Description
In this talk, we will present the results on the charmonium
decays with the $J/\psi$ and $\psi^\prime$ data samples
collected with the BESIII experiments at the BEPCII collider.
With the world largest data samples at these two peaks, we
observed for the first time many new decay modes of $J/\psi$,
$\psi^\prime$, $\chi_{cJ}$, and $\eta_c$, we also improve the
precisions of the branching fractions of some other decay modes.
