Aerial photo taken on Oct. 18, 2018 shows the Nuorilang waterfall at the Jiuzhaigou Valley Scenic Area in Jiuzhaigou County, southwest China's Sichuan Province. Water flow of the waterfall was once discontinued after a magnitude-7.0 earthquake in August 2017. The magnitude-7.0 earthquake that hit here on Aug. 8, 2017 and the flooding of this summer caused damages of various degrees to the Jiuzhaigou Valley Scenic Area, which has been temporarily closed since July for renovation.
