We review the results for observations of the Zc（3900） and Zc（4020） 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, and the search for e^＋e^-→γχcJ and γY（4140）. We also present data from BESIII that may further strengthen the study of the XYZ and conventional charmonium states, and discuss perspectives on future experiments.展开更多
