Abstract
Decay property of hidden-charm tetra-quark mesons is studied. It is seen that estimated width of iso-triplet odd partners of X(3872), although still crude, is compatible with the measured ones of Z_c(3900). It is pointed out that confirmation of an eta-pi^0 peak around 3.2 GeV indicated in gamma-gamma collisions gives a clue to select a realistic model of multi-quark mesons.
