Chéngchéng

Chengcheng lies in the loess uplands north of the Wei River. At Yaotou, in the western part of the district, potters worked the local clays to make ceramics and earthenware. A Ming gazetteer traced the craft to the Tang, while surviving finds include celadon and black wares from the Yuan. The kilns continued to work under the Ming and Qing; in the Yongzheng reign a local poet celebrated the smoke and fires of Yaotou's furnaces.
