Introduction to the Duan Xu Statue: The Duan Xu Statue is located at the east end of the Waterwheel Square, on the central axis of the south gate. In front of the statue is a 26-meter-diameter waterwheel pattern, which vividly reflects the scene where Duan Xu created the waterwheel. .
Duan Xu, courtesy name Shaoxian and alias Dongchuan, was born in Lanzhou. During the Jiajing period of the Ming Dynasty, he traveled to several provinces in the south. He developed a strong interest in the wooden barrel carts in the south, so he observed its structural principles and drew pictures. After returning to his hometown in his later years, he devoted himself to imitating waterwheels. After several failures, in the 35th year of Jiajing (1556), he made the Yellow River waterwheel with trumpet mouth lane, concave trough and giant wheel, which improved the farmland on both sides of the drought-laden Yellow River. Many benefits.
