Mount the horse. Lu is located in the Poyang Lake basin in the north of Jiangxi Province, Lushan District of Jiujiang City, bordering Poyang Lake and on the south bank of the Yangtze River. Jiujiang has a long history of development. During the Xia and Shang Dynasties, Jiujiang belonged to Jingyang and Yangzhou, and during the Spring and Autumn Period, Jiujiang belonged to the Western Chu of Soochow, so it was called "Wu Tou Chu Wei". Jiujiang, as an administrative division, first appeared in the Qin Dynasty. Qin Shihuang set 36 counties in the world, including Jiujiang County. Jiujiang has since been called Chaisang, Xunyang, Runan, Kancheng and Dehua. But it is mainly famous in Jiujiang, Chaisang, Xunyang and Jiangzhou.

In 22 1 year BC, after Qin Shihuang unified China, the whole country was divided into 36 counties with Jiujiang County as the boundary. In the Western Han Dynasty, Jiujiang built a county called Chai Sang, which is now Jiujiang City. In the sixth year of Gaohan (20 1 year BC), Guan Ying, a general riding a chariot, dug a well here to build a city for defense, and called it the city, also known as Guanying City. During the Three Kingdoms period, it belonged to Wu Dong and was transferred to Wuchang County. Jiujiang County was changed to Jiangzhou in the Tang Dynasty, Heyang County in the first year of Tianbao (742) and Jiangzhou in the first year of Gan Yuan (758). During the Five Dynasties and Ten Kingdoms, Jiangzhou was a place of moral education in the Southern Tang Dynasty, so Xunyang was changed to Dehua, Jiangzhou was abandoned, and Jiangzhou was restored in the Song Dynasty. In the Yuan Dynasty, the road was changed. At the end of the Yuan Dynasty, Chen Youliang claimed to be the emperor and made Jiangzhou his capital. The Ming Dynasty diverted to Jiujiang Prefecture, and the Qing Dynasty was ruled by the Ming Dynasty. After the Revolution of 1911, the imperial system was abolished, and Daoling County was established in 19 14, and Jiujiang House was changed to Heyang Road, which governed 20 counties, among which Dehua County was changed to Jiujiang County in 19 14 because it had the same name as Dehua County in Fujian Province.
