A walkway goes through ponds and islets at the “Fish Tail” sponge park that's built on a former coal ash dump site in Nanchang in north-central China's Jiangxi province on Sunday, October 30, 2022. The concept of the park involves creating and expanding parks and ponds within urban areas to prevent flooding and absorb water for times of drought. (Photo by Ng Han Guan/AP Photo)
