Aerial photo taken on Oct. 9, 2019 shows the Luoxingdun islet standing on the dried lake bed of Poyang Lake, China's largest freshwater lake, during its dry season in Lushan, east China's Jiangxi Province. As Poyang Lake enters the dry season, its lake bed becomes visible with criss-crossing mud cracks and many tourists see that as an alternative attraction. (Xinhua/Hu Chenhuan)
