  Fulfillment of the energy-momentum conservation law, as well as the charge,
baryon and lepton number conservation is checked for the HIJING Monte Carlo
program in $pp$-interactions at $\sqrt{s}=$ 200, 5500, and 14000 GeV. It is
shown that the energy is conserved quite well. The transverse momentum is not
conserved, the deviation from zero is at the level of 1--2 GeV/c, and it is
connected with the hard jet production. The deviation is absent for soft
interactions.
  Charge, baryon and lepton numbers are conserved.
  Azimuthal symmetry of the Monte Carlo events is studied, too. It is shown
that there is a small signature of a "flow". The situation with the symmetry
gets worse for nucleus-nucleus interactions.
