The BESIII experiment has accumulated a large sample of J/psi, psi' and psi(3770) data set. Through these charmonium radiative and hadronic decays, we can explore the light hadron spectroscopies. In this talk, we will report our recent results on the properties of the X states, such as X(1835) and X(p pbar), study of J/psi radiative decays (J/psi → γKKη , γπ+π-η', γπ0π0). In addition, we also present our results on the decays of light mesons η and η' at BESIII.
