Abstract：This talk will introduce our two recent works about the constraints on the number of inner horizons. In the first part I will discuss the inner horizon of spherically/planar/hyperbolically symmetric black hole with charged scalar. I will show that such a system has no inner horizon in spherically or planar symmetric case and has at most one inner horizon in hyperbolically symmetric case. In the second part we focus on general static black holes which have no additional symmetry. We will show that, with strong or null energy condition, the general static black hole will have only two Killing horizons associated with the Killing vector which stands for static symmetry.
