  A key question to QCD is what mechanism generates the hadron mass in the
light quark sector, where both confinement and chiral symmetry breaking are in
the game. Are confinement and chiral symmetry breaking in the vacuum uniquely
interconnected? Can hadrons survive chiral symmetry restoration? If yes, what
happens with their mass and what symmetries beyond the chiral symmetry are
there? We review our recent insights. In particular, in a dynamical lattice
simulation we artificially restore chiral symmetry by removing the low-lying
Dirac modes of the valence quark propagators, which is a well defined procedure
and keep gluodynamics intact. Hadrons survive this artificial chiral
restoration and their mass is surprisingly large. All hadrons fall into chiral
multiplets and some of them are degenerate, i.e. the spectrum reveals some
higher symmetry, that includes the chiral symmetry as a subgroup. The U(1)_A
symmetry does not get restored after removal of the chiral modes from the
valence quarks.
