  The following topics are considered. 1) Confinement, chiral dynamics, and
light scalar mesons. 2) Chiral shielding of the \sigma(600) 3)The \phi meson
radiative decays about nature of light scalar resonances. 4) The J/\psi decays
about nature of light scalar resonances. 5) The a0(980)\to\gamma\gamma and
f0(980)\to\gamma\gamma decays about nature of light scalar resonances. 6) New
round in \gamma\gamma\to\pi^+\pi^-, the Belle data. 7) The a0(980)-f0(980)
mixing: theory and experiment. Arguments in favor of the four-quark model of
the a0(980) and f0(980) mesons are given.
