Pupils have class at a school in Jino Ethnic Township on Jino Mountain in Jinghong of Xishuangbanna Dai Autonomous Prefecture, southwest China's Yunnan Province, June 11, 2019. With a population of slightly over 20,000, the Jino people had only been officially acknowledged in 1979 as an independent ethnic group of China. Until 1949, most of them had lived for generations in primitive mountain tribes in southwest China's Yunnan Province. Currently, the primary education in Jino Ethnic Township achieved 100 percent coverage for all school-age children. (Xinhua/Hu Chao)
