Description
In Belle experiment, many quarkonium-like exotic hadron candidates have been discovered, X(3872) in B meson decay, Y(4260) in initial state radiation, Zb(10610)+ and Zb(10650)+ in Upsilon(10860) decay and so on. This talk will review recent progress of relevant experimental studies as well as attempts to give a comprehensive interpretation for them.
