Introduction to Changhuai Ancient Town: Changhuaiwei Ancient Town is located on the south bank of the Huaihe River in Longzi Lake District. During the Sui and Tang Dynasties, it was a continent in the water of the Huaihe River. Because there are many white fine sands everywhere, when the wind blows, they will fly in groups, so It is called "Fantuanzhou". In the early Ming Dynasty, the Yellow River diverted the Huaihe River, silt accumulated, and the sandbar connected with the south bank of the Huaihe River, gradually forming a market town facing the Huaihe River in the north.
