  $C\!P$ violation in baryon decay processes is still undiscovered to date. We
present a general analysis of the decay-angular-distributions and the
corresponding $C\!P$ asymmetries in cascade decays of the type $\mathbb{H}\to
R(\to ab) c$, where $\mathbb{H}$ is a heavy hadron that decays through weak
interactions $\mathbb{H}\to R c$, and the resonance $R$ decays strongly via
$R\to ab$. Based on the analysis, we propose to search for $C\!P$ violation in
the decay-angular-distributions in the cascade decay processes ${\mathbb{B}}\to
\mathcal{B} M$, with $\mathcal{B}$ or $M$ subsequently decaying through strong
interactions, where ${\mathbb{B}}$ is the mother baryon, $\mathcal{B}$ or $M$
are the daughter baryon and meson, respectively, and $M$ has to be
spin-nonzero. We also present some typical decay channels in which the search
for such kinds of $C\!P$ asymmetries can be performed.
