Lǎngníng
Langning was an old county on the eastern bank of the You River, northwest of Nanning. It was created from Xuanhua in 622, when this part of Guangxi belonged to the Tang frontier administration of Nanjinzhou, later renamed Yongzhou. The county was absorbed into Xuanhua under the Song, but its name recalls an earlier centre on the river above the city of Yongzhou.
