  In this article, we investigate the $\bar{D}\Sigma_c$, $\bar{D}\Xi^\prime_c$,
$\bar{D}\Sigma_c^*$, $\bar{D}\Xi_c^*$, $\bar{D}^{*}\Sigma_c$,
$\bar{D}^{*}\Xi^\prime_c$, $\bar{D}^{*}\Sigma_c^*$ and $\bar{D}^{*}\Xi_c^*$
pentaquark molecular states with strangeness and without strangeness via the
QCD sum rules at length, pay much attention to the light flavor $SU(3)$
breaking effects, and make predictions for new pentaquark molecular states
besides assigning the $P_c(4312)$, $P_c(4380)$, $P_c(4440)$, $P_c(4457)$ and
$P_{cs}(4459)$ self-consistently. We can search for those pentaquark molecular
states in the decays of the $\Lambda_b^0$, $\Xi_b^0$ and $\Xi_b^-$ in the
future.
