  We reconstruct the interaction rate between the dark matter and the
holographic dark energy with the parameterized equation of states and the
future event horizon as the infrared cut-off length. It is shown that the
observational constraints from the 192 SNIa and BAO measurement permit the
negative interaction in the wide region. Moreover, the usual phenomenological
descriptions can not describe the reconstructed interaction well for many
cases. The other possible interaction is also discussed.
