BESIII has collected 1.3×108J/ψ1.3×108J/ψ and 0.4×108 of ψ′, which are the world’s largest data samples of J/ψ and ψ′ from e+e− collision. Radiative decays of charmonium provide a gluon-rich environment and are therefore regarded as one of the most promising hunting grounds for gluonic excitations. Significant progresses in the light-quark sector have been made with the unprecedented high statistics data sets. Several recent results on light hadron spectroscopy and light hadron decays will be reported, including: 1, the observation of the anomalous line shape of X(1835) near pˉp mass threshold and related studies; 2, studies of glueballs in J/ψ radiative decays; 3, search for 1−+ exotic in χc1→ηππ.
