Abstract
The BESIII experiment has collected $e^+e^-$ collision data samples corresponding to integrated luminosities of $2.93~\rm{fb^{-1}}$ and $3.19~\rm{fb^{-1}}$ at center-of-mass energies of $3.773~\rm{GeV}$ and $4.178~\rm{GeV}$, respectively. We report the measurements of strong phase differences in $D^{0}$ decays, including $K_{S/L}\pi^{+}\pi^{-}$ and $K_{S/L}K^{+}K^{-}$, which can reduce the systematic uncertainty of $\gamma/\phi_{3}$ measurement at LHCb and Belle II. In addition, we report the amplitude analyses and the measurements of the absolute branching fractions of $D^{+}$, $D^{0}$, and $D_{s}$ decays.
