Introduction to Hengcheng Ancient Ferry: As early as the Western Xia Dynasty, Hengcheng was the famous Hue Ancient Ferry with a history of more than 1,000 years. In the thirty-sixth year of Kangxi's reign in the Qing Dynasty (1697 AD), Emperor Kangxi crossed the Yellow River here during his western expedition to Galdan. He was impressed by the benefits of the Yellow River and left a message: "After crossing the mountains and crossing the river again, the sand was flat, the shore was wide and the water was waveless. , "Tangtangnan has gone to work and built sparsely, but this divided canal has many benefits" is a magnificent poem.
