Introduction to the source of the Raohe River: The Raohe River, one of the five major water systems of Poyang Lake, gave birth to the Muxin River, the earliest human culture discovered in Jiangxi so far. According to the investigation, the source of the Raohe River is at the "Chazhu Stele" site (the original Lotus Temple) on the upper part of the Banling Pavilion in Huiling, Duanxin Township, and the source is at the third main peak of Wulong Mountain (named after the Lotus Temple below) (For "Lotus Top"). This was also the national road and the main road for Duan Xin to enter and leave ancient Huizhou.
