City green lung within an ecological wetland, reed marshes and migratory birds create a natural scroll. Located in Changsha’s downtown area, Yang Hu Shi Di Gong Yuan is a rare ecological wetland model. Here, reed marshes, lotus ponds, and shallow wetlands form a three-dimensional ecological landscape. Every autumn and winter, it attracts tens of thousands of migratory birds to reside, white egrets, black-crowned night herons, and green ducks in the reed fields, creating a dynamic natural poem. The park features an ecological science corridor, through interactive devices to display the wetland food chain, visitors can walk along wooden boardwalks to observe otters, kingfishers, and other rare animals up close, and feel the rhythm of the wetland’s breath.
