    Quantum information transfer is one of the important branches in quantum infromation. Based on the single state quantum information transfer in spin chain, the transfer of two and three states information in spin chain are discussed in detail, and then the scheme is expanded to the arbitrary n states furthermore. Finally, the probability formula of the quantum information of the arbitrary n-state transfers in spin chain is obtained, and the condition that the arbitrary n-state information can be transferred perfectly in spin chain is given as well. Accordingly, a reasonable theoretical scheme is offered for the perfect transfer of the arbitrary n-state information.
