- In this presentation, we discuss the recent hadronic decays of charmed mesons observed in the BESIII experiment, specifically focusing on the decay processes $D^+ \to K_S^0 π^+ η$, $D^0 \to π^+ π^- η$, $D^+ \to π^+ π^0 η$, $D_s^+ \to π^+ π^+ π^- π^0$, $D_s^+ \to π^+ π^+ π^- π^0 π^0$, $D_s^+ \to K_S^0 K_L^0 π^+$, and $D^+ \to K_S^0 K_S^0 π^+$. We present results from amplitude analyses revealing rich structures in these decay processes. Furthermore, we report on the $ϕ$ decay ratio in $D_s^{\pm}$ decays. Our findings have significant implications for fundamental inputs related to non-perturbative QCD, hadronic matter structure, and studies of $\mathit{CP}$ violation.
