With the potential for the improvements of measurement precision, the refinement of theoretical calculation on hadronic B weak decays is necessary. In this paper, we study the contributions of B mesonic distribution amplitude within the QCD factorization approach, and find that contributes to only the nonfactorizable annihilation amplitudes for the B PP decays (P denotes the ground SU(3) pseudoscalar mesons). Although small, the contributions might be helpful for improving the performance of the QCD factorization approach, especially for the pure annihilation and decays.
