Abstract
In this talk, we review the most recent progress in the searching for the exotic hadrons, including hybrids, multi-quark states, molecules and so on. We only focus on the studies with a charmonium and one or more light mesons in the final states. This covers the X(3872), the states at around 3.940 GeV, the Y(4140) and X(4350) in two-photon collisions, the states from processes, and the charged states.
