In recent years, lots of studies of charmonium decays have been performed at BESIII based on large data samples of $J/psi$, $psi(3686)$ and $psi(3770)$. Recent results in searches for radiative transitions of $psi(3770)$ and rare phenomena in charmon
ium decays, and studies of light hadrons structures and properties will be presented.
Based on $psi(3686)$ decays of 106 million, the 1.31 billion J/psi events and a data sample of $psi(3770)$ with $2.9~fb^{-1}$ integrated luminosity, many analyses are performed. Exclusively baryonic decays of the $psi(3770)$, the radiative transition
$psi(3770)togammaeta_c(2S)$, the $psi(3770)$ transition to $chi_{cJ}$, isospin violation decay $chi_{c0,2}topi^0eta_c$, the $C-$parity violation decays $J/psitogammagamma,gammaphi$ are searched for, but no significant signals are observed, and upper limits are set for these decays. The decays of $psi(3770)togammachi_{c1}$ and $J/psitopi^0phi$ signals are observed. These measurements provide more information on the charmonium structure, and the isospin and $C$-parity violation in the charmonium decays.
Recent results on Charmonium decays are reviewed which includes two-, three- and four-body decays of $chi_{cJ}$ states, observations of Y(4260) through $pipi J/psi$ transitions, precise measurements of $M(D^0)$, $M(eta)$ as well as $mathcal{B}(etato X)$.
