Chengwu Big Millstone and Big Well

　　Chengwu Big Millstone is situated in Danianji Village, Chengwu County. During the Daoguang period of the Qing Dynasty, it was still well-preserved. Currently, the millstone trough and one millstone wheel remain. The trough consists of nine arcs of bluish-red and green stones of varying lengths with grooves, forming a circle with a diameter of 8 meters and a circumference of 25 meters. Both the trough and the wheel show clear signs of wear. Originally, there were two millstone wheels of different sizes, both disc-shaped. The smaller one had a diameter of about 1 meter and was buried underground. The larger one, with a diameter of 1.7 meters, is now placed in the center of the trough. According to the Caozhou Prefecture Records compiled during the Qianlong era of the Qing Dynasty, this millstone was “left behind by the garrison troops of Shi Hongzhao from the Later Han Dynasty. The millstone is still here, located twenty li northeast of the county.”

　　About one li east of the big millstone lies Danian Village, which has a large well. The original well opening was quite large but was gradually reduced through multiple renovations. The current well opening still has a diameter of over three meters. According to the Shi Family Genealogy, this well was also left behind by the garrison troops of Shi Hongzhao.
