The importance of the nuclear inputs for r-process calculation and the astrophysical condition constraints have been demonstrated by reproducing the r-process abundance around A=135 and 180 with the neutron-rich nuclear masses around N = 82 and 126 predicted by FRDM and WS* models as well as the observed r-process abundance peaks at A = 80, 130, and 195. During the last decades, the covariant density functional theory (CDFT) with a minimal number of parameters allows a very successful description of nuclear ground state as well as excited state properties all over the nuclear chart. In this talk, exotic phenomena predicted by CDFT including the halos in deformed nucleus in the deformed relativistic Hartree-Bogoliubov theory in continuum, the crucial test for CDFT with new and accurate large-scale mass measurements from Sn to Pa, the beta-decay half-lives for 20  Z  50 even-even neutron-rich nuclei in the fully self-consistent proton-neutron quasiparticle random phase approximation based on the relativistic Hartree-Fock-Bogoliubov theory, and the speeding-up of the r-matter flow with the beta-decay half-lives of the neutron-rich nuclei thus obtained, will be briefly reviewed.
