  In this proceeding, we present on our first measurements of identified
particle ($\pi$, $K$, $p$, $K_{s}^{0}$, $\Lambda$, $\phi$, $\Xi^{-}$)
production and anisotropic flow ($v_{1}$, $v_{2}$) in Au+Au collisions at
${\sqrt{s_{\rm NN}} = \rm{3\,GeV}}$. Various models including thermal and
transport model calculations are compared to data, these results imply that the
matter produced in the 3 GeV Au+Au collisions is considerably different from
that at higher energies.
