  We extend the nonrelativistic QCD framework to explore the nature of the
newly discovered di-$J/\psi$ resonances. Assuming them as either molecule-like
states or tetraquarks, we calculated their hadroproduction cross sections at
the LHC. We find that the observed resonances are most likely spin-2 particles,
and there should exist their spin-0 counterparts near these resonances. The
ratio of production cross sections of the observed resonances to the latent
spin-0 ones are also presented, which might help to distinguish molecule-like
states from tetraquarks.
