General situation of river basin:
The Huaihe River originates from Laoyacha, Tongbai Mountain, Nanyang City, Henan Province, flows eastward to Henan, Anhui and Jiangsu provinces, and enters the Yangtze River at Sanjiang Camp, with a total length of 1000 km and a total drop of 200 meters. The source of Huaihe River consists of 58 tributaries of Tongbai Mountain. The determination of the source of a river generally follows the principle of "the height is the source and the distance is the source".
Hu Aijing is designated as the main source of the Huaihe River for three reasons: First, the water level is the highest among the 58 tributaries of the Huaihe River (1 140m), which is the farthest from the East China Sea; Second, when Qin Shihuang was here, he established the Huai Temple, where the emperor offered sacrifices to the Huaihe River. 3. Records: Emperor Qianlong of the Qing Dynasty sent officials here twice to explore the source, and political envoy Jiang Lan and Henan Governor Bi Yuan both explored the real source of the Huaihe River here.
