We systematically study the mass spectra and their two-body hadronic decays of the beauty-charm meson family considering the coupled channel effects. Our results can good explain the observed Bc meson spectrum and the prediction of the mass spectrum for unobserved beauty-charm mesons can be tested in future experiments. For the coupled channel components, we predicted the 1S state in beauty-charm meson family is about 4%, while the 2S, 1P, 2P, 1D, and 2D states are about 14%, 10%, 33%, and 17% respectively. For the 3S, 2P and 2D states, the strong decay is allowed, The two-body hadronic decay widths of the 31S0, 33S1, 23P2 states are about 110 MeV, 69 MeV, and 3 MeV, respectively. While the two-body decay widths of the 23D1, 2D, 2D^′, and 23D2 states are 60 MeV, 149 MeV, 65 MeV, and 72 MeV, respectively.
