Abstract
Resent results from BESIII on charmonium spectroscopy and charmonium decays are presented. They include 1, the first measurement of the transition rates of ψ′→π0hc, hc→γηc, and improved measurements of the mass and width of hc; 2, observation of χcJ→VV, with VV being ϕϕ, ωω, and ωϕ; 3, improved measurements of the branching fractions of χcJ decays into two neutral pseudoscalar meson pairs χc0,2→π0π0 and χc0,2→ηη.
