Based on factorization theorem, we develop a theory called perturbative QCD approach to deal with non-leptonic two body B decays. We apply the Sudakov resummation to transverse momentum distribution of quarks. Using the light cone wave function, we calculate many decays of B meson. Our result of branching ratios agrees with the B factory experiment. Our prediction of CP asymmetry will be tested soon by experiments.
