Extended information:

According to Records of the Historian, the Yellow River flowed through Daming before the Western Han Dynasty, and dikes were generally built in the lower reaches of the Yellow River during the Spring and Autumn Period and the Warring States Period. However, the vassal States beggar their neighbors, and the dikes are irregular and unreasonable. After the Qin Dynasty unified China, the dikes were comprehensively rectified.

In the Han Dynasty, systematic dikes were further built, and masonry was constantly added, heightening and thickening, calling the dikes in the lower reaches of the Yellow River Golden Dikes, which conveyed people's good wishes for the Yellow River dikes to be firm and unbreakable. According to the Records of Daming County (Republic of China), "Jindi is an old dike in the Han Dynasty, which is as powerful as Gangling, which goes around the ancient Yellow River to open a state (now Puyang), Qingfeng and Nanle into the county, and the northeast is more than 211 miles long in Shandong Guantao (now Hebei Guantao)."

This 21-kilometer-long levee in daming county is the site of Jindi in the Han Dynasty. Wang Mang was well aware of the severe flooding of the Yellow River. After the establishment of the new dynasty, he stepped up the management of the Yellow River dikes and built golden dikes many times, which made the people seldom suffer from disasters. In order to commemorate Wang Mang's contribution to embankment construction, and because daming county (then called Yuancheng) was Wang Mang's hometown, people called it Wang Mang Dike.
