We study exclusive non-leptonic two-body Bc(D(s),hc,B(s))+F decays with F(pseudoscalar or vector meson) being factored out in QCD factorization approach. The non-leptonic decay amplitudes are related to the product of meson decay constants and the form factors for semileptonic Bc decays. As inputs in obtaining the branching ratios for a large set of non-leptonic Bc decays, we use the weak form factors for the semileptonic Bc(D(s),hc,B(s)) decays in the whole kinematical region and the unmeasured meson decay constants obtained from our previous light-front quark model. We compare our results of the branching ratios with those of other theoretical studies.
