Introduction to the Jiuqu Corridor: Stone Sea combines the landscape features of Guilin in Guangxi, Zhangjiajie in Hunan, and Lunan in Yunnan, forming its own unique style. The newly built stone paths for mountaineering are interspersed among them, and they are connected one after another. When people enter it, it is difficult to distinguish the east from the west. This group of landscapes is called the "Nine-curved Corridor".
