The vector Charmounium(-like) states $1^{--}$ could be generated via $e^{+} e^{-}$ collision and their properties are still mysterious.
Recently, more than 5$fb^{-1}$ data above 4 GeV are accumulated at BESIII, which supply a good chance to study these states.
In this paper, we present the studies of hadronic transitions including $e^{+}e^{-}\to\pi^{+}\pi^{-}J/\psi$, $e^{+}e^{-}\to\pi^{+}\pi^{-}h_{c}$,
$e^{+}e^{-}\to\pi^{+}\pi^{-}\psi(3686)$, $e^{+}e^{-}\to\omega\chi_{cJ}$, $e^{+}e^{-}\to\eta J/\psi$, $e^{+}e^{-}\to\eta'J/\psi$ and
$e^{+}e^{-}\to\pi^{0}\eta J/\psi$.
