To understand the nature of vector charmonium and charmonium-like states better, the measurements of the cross-section of e+ e- -> pi+ pi- J/psi, e+ e- -> K+ K- J/psi, e+ e- -> pi+ pi- psi2(3823), e+ e- -> D+ D- and e+ e- -> D*+ D- are performed at BESIII recently. This talk will include the new decay modes of the well-known resonance, such as Y(4230), and the new observed structures that strongly coupled to these channels.
