Aerial photo taken on April 17, 2018 shows the playground of the Central Primary School in Qiaozhuang Township of Qingchuan County, southwest China's Sichuan Province. Qingchuan was one of the worst-hit areas when a catastrophic earthquake struck Sichuan's Wenchuan County in 2008. On May 12, 2008, an 8.0-magnitude earthquake struck Wenchuan, razing almost the whole county to the ground. After ten years of hard work, Wenchuan has regained life. (Xinhua/Xue Yubin)
