Query: Restoration of QCD classical symmetries in excited hadrons   Restoration of chiral and $U(1)_A$ symmetries in excited hadrons is reviewed.
A connection of these restorations with the semiclassical regime in highly
excited hadron is discussed.
  A solvable confining field-theoretical toy model that exhibits chiral
restoration is presented. Implications of the string description of the highly
excited hadrons that suggests an additional dynamical symmetry of the spectra
on the top of $U(2)_L \times U(2)_R$ are presented.
