As a prototype of one-dimensional (1D) systems possessing Majorana zero modes at edges, Kitaev chain model has attracted a lot of attention since it was proposed. The pristine Kitaev chain is a non-interacting model and can be generalized to an interacting model. I shall talk about the exact solution to the (symmetric) interacting model, in the sense that all the eigenvalues and corresponding eigenstates are given. The solutions include topologically non-trivial phase at |U|<t and topologically trivial phase at |U|>t. The two phases are related by dualities. Quantum phase transitions in the model are studied with the help of the exact solution. Experimental consequences will be discussed too.
