Besides the populous Han nationality, China has 55 minorities with a population of 91.2 million, accounting for 8.04 percent of the country’s total. The area of the minority autonomous regions is 64.3 percent of the total national territory. Before 1949, almost all minority women in China were illiterate. Since the founding of New China, the female education among the minority nationalities has made great progress. According to the fourth national census, the female population of minorities over six years old is 38.18 million. Of these 15.3 million females have received a primary education; 7.展开更多
