Summary
The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII) has accumulated the world's largest samples of $e^+e^-$ collisions in the tau-charm region. Based on the samples taken at $\psi(3770)$ peak, around the $\psi(4040)$ nominal mass, and at the $\Lambda^+_c\Lambda^-_c$ mass threshold 4.6 GeV, we can study the charmed hadron decays under a uniquely clean background. In this talk, we will review the recent results on the $D$, $D_s$ and $\Lambda_c$ decays, such as the analyses of the purely leptonic and semi-leptonic decays of D meson, the measurements on strong phase and $D^0-\bar{D}{}^0$ mixing parameters using quantum coherence at threshold, $D$ Dalitz analyses, determination on the absolute branching fraction of $\Lambda_c$ hadronic decays and first model-independent study on the semi-leptonic $\Lambda_c$ decay rate $\mathcal{B}(\Lambda_c^+ \to \Lambda e^+ \nu$).
