Barren Land Turns Green with Brothers' Efforts to Plant Trees

Twin brothers Xu Zhigang (R) and Xu Zhiqiang, 74, drive a tricycle to check the trees in Zhangchuan Village of Tongwei County, northwest China's Gansu Province, June 15, 2022. Xu Zhigang and his twin brother Xu Zhiqiang have spent over 50 years voluntarily planting trees on barren hills on the Loess Plateau. More than 350 mu (about 23 hectares) of barren land have turned green with their plantation of tree seedlings. The brothers' efforts have not only helped create natural beauty but also improved local ecological environment. (Xinhua/Ma Xiping)
