This combination photo shows twin sisters Huang Xingqi and Huang Xingyi at their new home in the Yunqi poverty alleviation settlement in Yuping Dong Autonomous County of Tongren, southwest China's Guizhou Province (above, photo taken on Feb. 28, 2019); and their old residence, a plank house in a mountain village (below, file photo). Under a poverty alleviation campaign in winter 2007, four-year-old twin sisters Huang Xingqi and Huang Xingyi relocated with their parents from an impoverished mountain village to the Yunqi settlement in Yuping County. The twin sisters were enrolled in a nearby kindergarten in September 2018. The family, which is from the local Dong ethnic group, had lived in a battered plank house back on the mountain before moving to their present three-storey residence, which offers substantially improved living conditions.
