Query: $J/{\psi}$ ${\to}$ $DP$, $DV$ decays in the QCD factorization approach   Motivated by the recent measurements on nonleptonic $J/{\psi}$ weak decays at
BESIII and the potential prospects of $J/{\psi}$ meson at the high-luminosity
heavy-flavor experiments, the branching ratios of the two-body nonleptonic
$J/{\psi}$ ${\to}$ $DP$, $DV$ decays are estimated quantitatively by
considering the QCD radiative corrections to hadronic matrix elements with the
QCD factorization approach. It is found that the Cabibbo favored $J/{\psi}$
${\to}$ $D_{s}^{-}{\rho}^{+}$, $D_{s}^{-}{\pi}^{+}$,
$\overline{D}_{u}^{0}\overline{K}^{{\ast}0}$ decays have branching ratios
${\gtrsim}$ $10^{-10}$, which might be promisingly detectable in the near
future.
