We in the paper study the metric perturbations generated in a bouncing
universe driven by the Quintom matter. Firstly, we review the background
evolution of Quintom Bounce and the power spectrum of scalar perturbations.
Secondly, we study the non-Gaussianity of curvature perturbations and then
calculate the tensor perturbations of the model.
