We consider the contact, one-pion and two-pion exchange interactions and bridge the low energy constants of the $\\Sigma_c\\Sigma_c$ system to those of the $\\Sigma_c^{(*)}\\bar{D}^{(*)}$ systems through the quark-level ansatz for the contact interaction. We explore the influence of intermediate channels in the two-pion exchange diagrams of the $\\Sigma_c\\Sigma_c$ system. We obtain a deep bound state $[\\Sigma_c\\Sigma_c]_{J=0}^{I=0}$ and a shallow bound state $[\\Sigma_c\\Sigma_c]_{J=1}^{I=1}$.
