We study possible chiral symmetry restoration patterns in a generalized hidden local symmetry model, including pseudo-scalar, vector and axial-vector mesons. We find three types of the chiral restoration, which are classified as the standard, vector manifestation and intermediate scenarios, respectively. The rho and A_1 meson become massless in all the restoration patterns. These three scenarios are different in the violation of the vector meson dominance, which will be reflected on the pion background in the spectrum of dilepton decay from the vector meson.
