Yǔchéng
Yucheng stands on the plain north of the Yellow River, its name recalling Yu the Great, the legendary ruler celebrated for controlling floods. The county seat moved to Shancun in 759 under the Tang. Local accounts describe a temple in the town and a pavilion on Juqiu Hill dedicated to Yu, where officials and residents offered sacrifice in memory of his work. The pavilion remained a place of worship into the Qing, linking the county's name with its traditions of water control.
