We find that the CP violating asymmetry is large via $\\rho-\\omega$ mixing mechanism when the invariant mass of the $\\pi^{+}\\pi^{-}$ pair is in the vicinity of the $\\omega$ resonance. For the decay of $\\bar{B}_{s}^{0} \\to K^{0}\\rho^{0}(\\omega)\\to K^{0}\\pi^{+}\\pi^{-}$, the maximum CP violating asymmetries can reach about 46%.
