Who knows the history, legend and changes of the small white river in Renqiu?

Xiaobaihe: It starts from Beizhangzhuang in Anguo County, flows through Anping County, enters Boye County from 0.6 km above Pangzhuang, passes through Nanpangzhuang Village, dong wang zhuang cun, Nandunzhuang Village, Liujiazuo and Lixian in Beidu Tianzhuang Village, and flows into Renwen Drainage Channel through Suning, Hejian, Levin and Renqiu County, which is the main drainage channel on the left side of the river. Boye County was originally an ancient river drainage ditch, which was excavated into a river in the spring of 1945. The design standard is once every five years, with a bottom width of 4-5m, an upper mouth width of 18m, a depth of 3m, a longitudinal slope of 1/3000 and a slope length of 1: 2. The design flow color is 24 cubic meters per second, and the basement soil is cohesive soil, including Fossey, and the domestic section is 10.94 km. Because the river flows through the saline-alkali land, it is white everywhere, and it is also white after the river dries up, so it is called Xiaobaihe, with a county area of 60 square kilometers. Xiaobaihe River is the main drainage channel between Zhulong River and Hutuo River, located at the junction of Baoding City and Cangzhou City. Its source can reach Lixian and Anping, and it flows northward into Renwen main canal in the northwest of Renqiu. Historically, there was no Zuo Di (north dike) in Hutuo River, and flood freely flooded northward in flood season, forming two major tributaries in the east and west, with the west tributary called West Zhi Zi and the east tributary called Xiaobaihe. In the process of years of flooding, the west branch gradually silted up and became a flat land, leaving only a shallow ditch shape on the Xiaobaihe River. After the founding of New China, Xiaobaihe River has been excavated and dredged many times, becoming the main drainage channel south of Daqing River.
