Su Shi's poem is Yunyang, with the words "Seeing the guests off at night in Yangjiang, where maple-leaves and full-grown rushes rustled in the autumn" at the beginning, indicating the time and place, Yunyang, now Xunyang County, Shaanxi Province. Xunyang County was set up in the Qin Dynasty, and Xunyang County was set up in the Han Dynasty. Xunyang was changed to Xunyang in the Western Wei Dynasty. Because the word "Xun" was uncommon and difficult to recognize, it was changed to Xunyang County with the approval of the State Council in 1964. In 1981, the fossil of the ancient saber-toothed elephant tooth unearthed in Honghuaping, Ganxi Town showed that in ancient times hundreds of thousands of years ago, Xunyang had the natural conditions of mild climate, lush forests and abundant water, which was suitable for ancient human life.

At the end of Shang Dynasty, when King Wu attacked Zhou, the "Yong" people in his allied forces were active in the water-blocking basin in the west of Yunyang, Hubei Province and Ankang, Shaanxi Province, including Xunyang.

During the Spring and Autumn Period, mediocre people were once one of the advanced ethnic groups in Daba Mountain area. Later, with the sealing of Xiong Yi, Chu became stronger and stronger, and the mediocrity gradually weakened. In 611 BC (the third year of Chu Zhuangwang), Chu was hungry, and mediocre people defected. According to Ge Jia's plan, Chu people joined forces with Qin people and Ba people to destroy Yong country. Since then, Xunyang area belongs to Chu State.

in 581, the sui dynasty was established, and in 583, tianxia county, Yunyang county and Jia county were abolished. In 67, the county was unified by the county, and the two counties of Yunyang and Huangtu were divided into Xicheng County and Shangjin County.

At the end of 617, Tang King Li Yuan sent Li Xiaogong as a consort of Shannan Road and occupied Xicheng County. In 618, Li Yuan forced Emperor Yang You to give way and established the Tang Dynasty. In that year (the first year of Wude), Xicheng County was changed to Jinzhou, which belonged to Yunyang County, and Shangjin County was changed to Shangzhou, which belonged to Loess County. In that year, Yunyang County was divided into three counties: one was Yunyang City (whose jurisdiction is equivalent to Xunhe River Basin in the northern part of Xunyang County today), the other was Yunyang (whose jurisdiction is equivalent to the surrounding area of Xunyang County today), and the other was Luchuan (whose jurisdiction is equivalent to Luhe River Basin in the southern part of Xunyang County today). In 624, the abandoned state was under the jurisdiction of Jinzhou. In 627, Lvchuan County was merged into Yunyang County. In 634, Yuncheng County entered Yunyang County. In the same year, Huangtu County, which has been abandoned in Shangzhou, was subordinate to Jinzhou.

In 742, Jinzhou was changed to Ankang County, and Huangtu County was changed to Zhiyang County. In 757, Su Zong Li Heng hated An Lushan and the word "An", and changed Ankang County to Hannan County (also known as Hanyin County). In 758, Hannan County (Hanyin County) was renamed as Jinzhou. In 771, Yunyang County, the province. In 821, Qingyang County was restored. In the Tang Dynasty, Jinzhou successively belonged to Shannan Road, Shannan West Road (governing Xingyuan House, now Hanzhong City), Gyeonggi Road (governing Chang 'an, now Xi 'an City) and the defense envoy of Zhaoxin Army.

at the end of the Tang dynasty, after Zhu Wen usurped the Tang dynasty, Wang Jian proclaimed himself emperor in Chengdu, and established Qianshu (one of the ten countries). Yunyang County and Zhiyang County were owned by Qianshu, and they were subordinate to Jinzhou Xiongwu Army. In 925, after Tang Zhongzong destroyed Shu, Yunyang and Yunyang counties belonged to the later Tang Dynasty, and belonged to Jinzhou Rongzhaojun. In 936, Shi Jingtang destroyed the later Tang Dynasty and was named Jin. Yunyang and Yunyang counties were changed to the latter Jin Dynasty. In 947, Liu Zhiyuan proclaimed himself emperor on behalf of the later Jin Dynasty, with the title of Han, and the two counties of Yunyang and Yunyang belonged to the later Han Dynasty. In 951, the Ministry of Liu Zhiyuan took Guo Wei as the Han Dynasty, and the name was Zhou, and the two counties of Yunyang and Yunyang were returned to the later Zhou Dynasty. In the later Jin Dynasty, the later Han Dynasty and the later Zhou Dynasty, the two counties of Yunyang and Yunyang were all under the control of the Huaide Army in Jinzhou.

in 96 (the seventh year after Zhou Xiande), Song Zhou, who had mastered the military power, was transferred to Zhao Kuangyin, our German military envoy, who instigated the "Chen Qiao mutiny", proclaimed himself emperor on behalf of Zhou, and established the Song Dynasty for the Northern Song Dynasty. In 966, Yunyang County, a province, entered Yunyang County, and the territory of Xunyang County has been defined since then. During the Northern Song Dynasty, a Zhili in Yunyang County was located in Jinzhou, which belonged to the southwest road of Beijing and was changed to the Zhaohua Army.
