Neural network methods have shown promise for solving complex quantum many-body systems. In this study, we develop a novel approach through incorporating the density-matrix renormalization group (DMRG) method with neural state method. The results demonstrate that, when tensor-network pre-training is introduced into network, high efficiency can be achieved systems strong correlations.
