Summary
The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII) has accumulated the word's largest $e^+e^-$ collision samples at $\psi$(3770) peak, around the $\psi$(4040) nominal mass, and at the $\Lambda_c^+\bar{\Lambda}_c^-$ mass threshold which allow us to study decays of charmed mesons and baryons in a uniquely clean background. In this talk, we will review our recent results including: (1) the extractions of the $D_{(s)}^+$ decay constants, the form factors of $D$ semi-leptonic decays, and the CKM matrix elements $|V_{cs(d)}|$; (2) the determinations of the absolute branching fractions of the hadronic and semi-leptonic decays of $\Lambda_c^+$.
