Introduction to the White Horse Rein: In the middle of the Yellow River in Shapotou, there is a 2,000-meter-long embankment that goes straight into the middle of the river. The turbulent river water overflows from the embankment, turning up a surging wave and sending out Thunderous sound of waves. This is a masterpiece of ancient ancestors, similar to the Meili Canal mouth dam of Zhongwei's largest Yellow River diversion irrigation water conservancy project in Dujiangyan, Sichuan. The ancestors created miracles, but they did not dare to believe in their own power, so the myth and legend of "White Horse Rein" came into being, adding a new scene to Shapotou. There are countless colorful and eccentric Yellow River pebbles on the embankment. They are colorful and dazzling in the water. You can easily get them without spending any money.
