Pǔníng

Puning was the seat of Rongzhou in southeastern Guangxi, among hills crossed by the Xiu River. The county acquired its name in 599, under the Sui, and became the prefectural seat in the Tang. Its walls were attributed to the Tang official Wei Dan and repaired on their old foundations in the early Ming. In 1377 the Ming abolished Puning County and incorporated it into Rongzhou, which was itself reduced to a county under Wuzhou Prefecture.
