  In the present work, the strong decays of the newly observed $P_{cs}(4338)$
as well as its high isospin cousin $P_{cs}(4460)$ are studied via the QCD sum
rules. According to conservation of isospin, spin and parity, the hadronic
coupling constants in four decay channels are obtained, then the partial decay
widths are obtained. The total width of the $P_{cs}(4338)$ coincides with the
experimental data nicely, while the predictions for the $P_{cs}(4460)$ can be
testified in the future experiment, and shed light on the nature of the
$P_{cs}(4338)$.
