Forest ranger Chen Guangren patrols in the ecological forest of the Yuanbao Village in Shangzhi city, northeast China's Heilongjiang province, April 25, 2019. 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)
