Despite numerous studies on the $P_{c\\bar{c}}(4440)$ and $P_{c\\bar{c}}(4457)$ heavy states, their spin states have not been previously determined. In this study, heavy symmetries are applied to predict the spin states. If the $P_{c\\bar{c}}(4440)$ and $P_{c\\bar{c}}(4457)$ states are considered $\\bar{D}^*\\Sigma_c$ molecules, they can be classified as heavy partners. This classification may help clarify their potential connections with heavy antiquark-diquark symmetry partners.
