Introduction to water rafting in the Huangpu River Source Wetland: Water rafting in the Huangpu River Source Wetland is mainly concentrated in the nearly 600 acres of wetland bamboo forest next to the east gate of the scenic spot, surrounded by a "mother river" - Xitiao Creek. The light bamboo forest flows through it, just like a gauze ribbon, and the clear river water supports the people of Anji; its source is the source of the Huangpu River.
