Aerial photo taken on April 24, 2019 shows residences in the Yuanbao Village in Shangzhi city, northeast China's Heilongjiang province. Yuanbao was once called "a village of bare-buttocks" because of its poorly-clad villagers. But today, Yuanbao villagers are no longer poor as they earn a per capita income of 31,000 yuan (4,604 U.S. dollars) as of 2018, thanks to a series of reforms. (Xinhua/Wang Jianwei)
