Located in the high mountains and deep valleys along the Jinsha River, Luquan Yi and Miao Autonomous County in Yunnan Province is one of the key counties in poverty alleviation and development work in China with a wide range of poverty and deep poverty. To enable children in poor areas to receive a good education is not only an important task of poverty alleviation and development, but also an important way to block the intergenerational transmission of poverty. Because of the complexity and difference of geography, history and culture, and the particularity and diversity of educational development appeal, it is often difficult to carry out poverty alleviation through education. Poor counties develop well education so that poor counties have new achievements. In recent years, Luquan County has adhered to the concept of "vigorously developing education" by making every effort to create a characteristic project with education to help the poor, and strived to achieve the "six solutions" so that every child can enjoy quality and fair education, and ensure that "they can get in, stay and learn well". This shows the new look of Miao and Yi mountains in the new era. This paper analyzes and summarizes the specific methods and effects, characteristics and bright spots of accurately building the model of "well education in poor county" in this county, as well as the experience gained, and the lessons, in order to provide the necessary reference for the poor counties in Yunnan Province and other similar provinces (municipalities, autonomous regions) to carry out rural poverty alleviation by education.展开更多

The per capita income reached 5,318 yuan (8.27 yuan against US dollar) in 2002. Yet some households in the county are still living in poverty. To get them rid of poverty, the county government has launched a poverty alleviation project, which has involved some 160 government institntions, enterprises, schools and other units. An official review on the project last year found that good results had been achieved in poverty alleviation. In 2002 alone, 199 households had been helped to shake off the poverty and move towards a relatively comfortable life.展开更多
