## Content

We present our studies of renormalization constants of non-singlet overlap quark bilinear opertors on 2+1-flavor domain wall configurations. The renormalization is performed in RI/MOM and RI/SMOM schemes. We compute the scale-independent renormalization constant for the axial vector current via the Ward identity both in the two schemes and obtain other RCs from $Z_A$. We compare the difference between RI/MOM and RI/SMOM schemes before and after converted to $\overline{\text{MS}}$ scheme for overlap fermions. The lattice is of size $48^3\times64$, of spacings $a=(1.73)^{-1}$, and the mass of pion of which is at physical point.
