Using the chiral unitary approach, combining with the heavy quark spin symmetry, we investigate the interactions of $J/\psi N$ with its coupled channels and look for the dynamical resonances in the interactions. One of the two $P_c$ states, $P_c (4450)$, found by LHCb experiments, is explained as a $\bar{D}^* \Sigma_c$ bound state in our theoretical model. To understand the properties of this state, we also study the $J/\psi N$ cross sections, the s-/u- channel contributions, and the $\Lambda_b^0 \to J/\psi K^- (\pi^-) p$ decays.
