Introduction to Hongya Danjing: It is one of the "Ten Scenic Spots in Yuzhang (ancient Nanchang)" and is located on the Wujingyuan Stream in the north of the bay. The cliffs are steep, and the waterfall comes from the north. The lower cave, formerly known as Hongjing Cave, is about more than 30 square meters and unfathomable. The two sides are so steep that no one dares to approach.
