The predictions of QCDF are in good agreement with experiments. The best fitted CKM angel gamma is around 79 degree. The predicted branching ratios of B --> pi^0 pi^0, omega K^+, omega pi^+, pi^+ K^{{\ast}0} etc. are also in good agreement with new data of BaBar and BelleRevtex4, 12 pages, 4 figures, Talk given at the International Conference on Flavour Physics, Seoul, Korea, 6--11 October, 2003High Energy Physics - Phenomenologytext
