The strange hadronic matter with nucleon, Lambda -hyperon and Xi -hyperon is studied by using a chiral symmetry model in a mean-field approximation. The saturation properties and stabilities of the strange hadronic matter are discussed. The result indicates a quite large strangeness fraction (fs) region where the strange hadronic matter is stable against particle emission. In the large fs region the Xi component dominate, resulting in a deep minimum in the curve of the binding energy per baryon E-B versus the strangeness fraction fs with (E-B, fs) similar or equal to (-26.0 MeV, 1.23).
