Abstract: The important role played by chiral symmetry and axial anomaly in QCD innuclear physics is reviewed. Some recent topics on possible chiral restorationin hot and-or dense matter are picked up. We also discuss so called {\emeffective} restoration of chiral anomaly hot and-or dense matter, as may beseen in a character change of $\eta -$ meson.
