BESIII has collected 2.93 fb-1 of data at 3.773 GeV, 6.3 fb-1 of data between 4.18 and 4.23 GeV, and 4.4 fb-1 of data between 4.6 and 4.7 GeV, respectively. The data set collected at 3.773 GeV contains quantum-correlated D0D0bar pairs that allow access to the phase differences between amplitudes. We will report the measurements of strong phase differences in D0(-bar) decays, such as K_S/L pi+ pi-, K_S/L K+ K-, K- pi+ pi0 and K- pi+ pi+ pi-, which are key to constraining the future gamma/phi3 measurements at LHCb and Belle II. In addition, we will present the measurements of the absolute branching fraction or amplitude analysis of hadronic decays of D+, D0, Ds+ and Lambda_c+.
