  Based on a data sample of 983 fb$^{-1}$ collected with the Belle detector at
the KEKB asymmetric-energy $e^+e^-$ collider, we present the study of the
heavy-flavor-conserving decay $\Xi_{c}^{0}\to \Lambda_{c}^{+}\pi^{-}$ with
$\Lambda_{c}^{+}$ reconstructed via its $pK^{-} \pi^{+}$ decay mode. The
branching fraction ratio $\mathcal{B}(\Xi_{c}^{0}\to
\Lambda_{c}^{+}\pi^{-})/\mathcal{B}(\Xi_{c}^{0}\to \Xi^{-}\pi^{+})$ is measured
to be $0.38 \pm 0.04 \pm 0.04$. Combing with the world average value of
$\mathcal{B}(\Xi_{c}^{0}\to \Xi^{-}\pi^{+})$, the branching fraction
$\mathcal{B}(\Xi_{c}^{0}\to \Lambda_{c}^{+}\pi^{-})$ is deduced to be $(0.54
\pm 0.05 \pm 0.05 \pm 0.12)\%$. Here, the uncertainties above are statistical,
systematic, and from $\mathcal{B}(\Xi_c^{0} \to \Xi^{-}\pi^{+})$, respectively.
