Cultural diversity is essential to human being as biological diversity is absolutely necessary to sustain the ecological equilibrium. Adopting minority languages and characters in the bilingual education is very important to the protection of cultural diversity. The ethnic Bai people have gained great achievements in the light of protecting cultural diversity through bilingual education of Bai and Han characters since the establishment of the People’ s Republic of China,but some conceptual obstacles still remain for further development of the Bai language,which also emerge in some other ethnic groups. So,to conduct intensive approach on these issues and to understand them rationally will be helpful for the better ethnic education and for the training of more members who love their homelands and human beings in the new period. Presently,some works still need to be done in terms of the education of Bai characters and the protection of the Bai culture.
