Abstract: With 5.1 fb-1 of data taken at s=3.8~4.6 GeV, BESIII made a significant contribution to the study of charmonium-like states, i.e., the XYZ states. We review the results of observations of the Zc states, the X(3872) in e+e- annihilation, and charmonium ψ(13D2) state, as well as measurements of the cross-sections of ωχcJ and ηJ/ψ.

Key words: charmonium-like, initial state radiation (ISR), exoitic
