Donation Proposal
Dongxiang Autonomous County is located in a poverty-stricken remote mountainous area in central Gansu Province. The county has a population of 266,900, of whom 83.97 percent are of Dongxiang ethnic community. Harsh natural conditions and drought have left the Dongxiang people living at the mercy of the heavens. For many school-age children, going to school is but a distant dream. School facilities are very backward. About 40 percent of primary schools are in a shabby condition and need to be reconstructed. There is neither modern education equipment and installations, nor is there any newly established school-run or village-run education centre. Therefore, your’ earing and selfless support is needed. The donation will be strictly used for building a Hope School in the area. According to local situation, about 200,000 yuan can help enlarge and furnish a school and about 300,000 yuan can help build a new one.
