  The strong decays of two narrow mesons $D_{s0}^{*}(2317)$ and
$D_{s1}^{'}(2460)$ are studied within the framework of heavy hadron chiral
perturbation theory. Up to next-to-leading order in $1/\Lambda_{\chi}$, by a
fit to the experimental widths of their nonstrange partners, the chiral
symmetry-breaking coupling constants are extracted. The single-pion decay
widths are estimated to be $\Gamma(D_{s0}^{*}(2317)\to
D_{s}^{+}\pi^{0})=9.2\pm2.3$ KeV and $\Gamma(D_{s1}^{'}(2460)\to
D_{s}^{*+}\pi^{0})=9.0\pm2.1$ KeV, respectively, which are consistent with the
experimental constraints and comparable with other theoretical predictions. The
numerical analysis shows that chiral-symmetry corrections to the decay widths
are significant. Applications and predictions for the corresponding beauty
mesons are also provided.
