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.
