Please refer to the historical evolution of Qidong County, Hengyang City, Hunan Province.

1952, Qidong and Qiyang were divided. Because most of the land is located in the east of Qiyang, it was named Qidong. Qidong has a long history. In the Spring and Autumn Period, it belonged to Southern Chu, and in the Western Han Dynasty, it belonged to Quanling Houguo. From the first year of Xing Wu in Wu to the fourth year of Tianqi (264-280), the whole mausoleum was located in Yongchang and Qiyang counties, with brick ponds and bridges in the county metallurgy. After the Northern and Southern Dynasties did not change, Yongchang and Qiyang merged into Lingling in the ninth year of Emperor Wendi (589). In the fourth year of Tang Wude (62 1), Qiyang County was restored. In the first year of Zhenguan of Emperor Taizong (627), the provinces, counties and Qiyang counties were abolished, and Zhenguan was restored in four years, which remained unchanged until the Song, Yuan, Ming and Qing Dynasties and the Republic of China. After the founding of New China1April, 952, all the seven, eight, nine and ten districts and most of the five and six districts in Qiyang County were set aside to establish Qidong County, with the county seat located in Hongqiao Town on the Xianggui Line. In 2004, Qidong county administered 19 town and 4 townships.
