### Description

At BESIII, the lineshapes of $e^+e^- ->\phi \eta', \phi \eta, K K, \omega \pi^0, \eta \pi \pi,$ and $\omega \pi \pi$ are measured from 2.0 to 3.08 GeV, where resonant structures are observed in these processes. Multiple lineshapes of intermediate state are obtained by a partial wave analysis of $e^+e^- ->K^+ K^- \pi^0 \pi^0, K^+K^- \pi^0$ and the structures observed provide essential input to understand the nature of $\phi(2170)$. These results provide important information for light flavor vector mesons i.e. excited $\rho, \omega$ and $\phi$, for energy regions above 2 GeV.
