  Using VISHNU hybrid model, we calculate the $p_{\rm T}$-spectra and elliptic
flow of $\Lambda$, $\Xi$, and $\Omega$ in 200 A GeV Au+Au collisions.
Comparisons with the STAR measurements show that the model generally describes
these soft hadron data. We also briefly study and discuss the mass ordering of
elliptic flow among $\pi$, $K$, $p$, $\Lambda$, $\Xi$, and $\Omega$ in minimum
bias Au+Au collisions.
