  In this work, we systematically study the two-body strong decay of the
$\rho/\rho_3$ states, which are observed and grouped into the $\rho/\rho_3$
meson family. By performing the phenomenological analysis, the underlying
properties of these states are obtained and tested. What is more important is
that abundant information of their two-body strong decays is predicted, which
will be helpful to further and experimentally study these states.
