We investigate the generation of nonclassical state via two-axis counter twisting interactions. By the bosonization method, we analytically and numerically calculate the spin squeezing parameter and the entanglement parameter. Its shows that the strength of the nonlinear interaction and the orientation of spin squeezing play important role in generating nonclassical states.
