We analyze charmless two-body non-leptonic B decays 
under the framework of a factorization-assisted topological-amplitude approach, where P(V) denotes a light pseudoscalar (vector) meson. Compared with the conventional flavor diagram approach, we consider the flavor SU(3) breaking effect assisted by a factorization hypothesis for topological diagram amplitudes of different decay modes, factorizing out the corresponding decay constants and form factors. The non-perturbative parameters of topology diagram magnitudes 
and the strong phase 
are universal; they can be extracted by 
fit from current abundant experimental data of charmless Bdecays. The number of free parameters and the per degree of freedom are both reduced compared with previous analyses. With these best fitted parameters, we predict branching fractions and CP asymmetry parameters of nearly 100 
and 
decay modes. The long-standing 
and 
-CP puzzles are solved simultaneously.
