  Stimulated by the new discovery of $P_{c}(4312)^{+}$ by LHCb Collaboration,
we endeavor to perform the study of $P_{c}(4312)^{+}$ as a $\Sigma_{c}\bar{D}$
state in the framework of QCD sum rules. Taking into account the results from
two sum rules, a conservative mass range $4.07\sim4.97~\mbox{GeV}$ is presented
for the $\Sigma_{c}\bar{D}$ hadronic system, which agrees with the experimental
data of $P_{c}(4312)^{+}$ and could support its interpretation as a
$\Sigma_{c}\bar{D}$ state.
