  Very recently, three new structures $\Xi_c(2923)^0$, $\Xi(2938)^0$, and
$\Xi(2964)^0$ at the invariant mass spectrum of $\Lambda_c^{+}K^{-}$ observed
by the LHCb Collaboration triggers a hot discussion about their inner
structure. In this work, we study the strong decay mode of the newly observed
$\Xi_c$ assuming that the $\Xi_c$ is a $\bar{D}\Lambda-\bar{D}\Sigma$ molecular
state. With the possible quantum numbers $J^p=1/2^{\pm}$ and $3/2^{\pm}$, the
partial decay widths of the $\bar{D}\Lambda-\bar{D}\Sigma$ molecular state into
the $\Lambda_c^{+}K^{-}$, $\Sigma_c^{+}K^{-}$,and $\Xi_c^{+}\pi^{-}$ final
states through hadronic loop are calculated with the help of the effective
Lagrangians. By comparison with the LHCb observation, the current results of
total decay width support the $\Xi(2923)^0$ as $\bar{D}\Lambda-\bar{D}\Sigma$
molecule while the decay width of the $\Xi_c(2938)^0$ and $\Xi(2964)^0$ can not
be well reproduced in the molecular state picture. In addition, the calculated
partial decay widths with $S$ wave $\bar{D}\Lambda-\bar{D}\Sigma$ molecular
state picture indicate that allowed decay modes, $\Xi_c^{+}\pi^{-}$, may have
the biggest branching ratios for the $\Xi_c(2923)$. The experimental
measurements for this strong decay process could be a crucial test for the
molecule interpretation of the $\Xi_c(2923)$.
