  We discuss whether the bi-maximal mixing given at GUT is consistent with the
solar mixing at the normal side at the low energy. We consider the radiative
corrections due to the tau-Yukawa, the neutrino-Yukawa and the slepton
threshold corrections and discuss in what situation the maximal solar angle
rotates towards the normal side. In this scheme, the |V_{13}| and the Dirac CP
phase delta are induced radiatively and we estimate these values.
