Language education plays a crucial role to facilitate the stability, prosperity and harmony of border ethnic minority areas. The education of Yunnan border ethnic areas has long been in the forefront of neighboring countries, but after the 1990s, the economic and social development in the border ethnic areas of Yunnan has been far behind compared with the coastal developed areas. Due to the large and deep poverty in the border towns, the masses can hardly afford the high cost of children's education, resulting in the low enrollment rate and high dropout rate in the border ethnic areas. For this reason, Yunnan took the lead in practicing the "three free" education in border ethnic areas, and then carried out the "two exemptions and one subsidy" education with the whole country. At the same time, in view of the complicated and diversified trend of languages in border areas, a bilingual pilot school project was implemented in the stage of compulsory education. This measure not only completely reversed the flow of students at home and abroad, but also provided a feasible basis for the idea of building a pluralistic and integrated community.
