In this article, we investigate the N-soliton bound state (BS) motions in photonic lattices. BSs split into their constituent single-solitons when they are incident normally into lattices. The splitting is sensitive to the incident position with respect to the lattices. In such a process, the lattice profile not only provides an antisymmetric frequency modulation perturbation and causes the BS to split but also acts as an external potential which affects the propagating dynamics of each single-soliton.
