The BESIII experiment has collected the $e^+e^-$ collision data samples corresponding to integrated luminosities of 2.93 $\mathrm{fb}^{-1}$, $3.19$ $\mathrm{fb}^{-1}$, 3.13 $\mathrm{fb}^{-1}$ and 567 $\mathrm{pb}^{-1}$ at center-of-mass energies of 3.773 GeV, 4.178 GeV, 4.189-4.226 GeV and 4.599 GeV, respectively. We report the measurements of strong-phase parameters based on the decays $D^0\to K^0_{S/L}π^+π^-$, $D^0\to K^0_{S/L}K^+K^-$, $D^0\to K^-π^+π^+π^-$ and $D^0\to K^-π^+π^0$, which are important input for binned model-independent measurement of the CKM angle $γ/ϕ_3$. In addition, we report amplitude analyses and branching fraction measurements of $D^+$, $D_s^+$ and $Λ_c^+$ decays along with the $Λ_c^+$ spin determination.
