  The paper suggests a left-right mirror symmetric model to account for the
baryogenesis and asymmetric dark matter. The model can simultaneously
accommodate the standard model, neutrino physics, matter-antimatter asymmetry
and dark matter. In particular, it naturally and elegantly explains the origin
of the baryon and dark matter asymmetries, and clearly gives the close
interrelations of them. In addition, the model predicts a number of interesting
results, e.g. the cold dark matter neutrino mass is $3.1$ times the proton
mass. It is also feasible and promising to test the model in future
experiments.
