Historical evolution of Yibin
In the Qin Dynasty, Bodao County, the first county-level administrative organization, was set up in Yibin City. Bodao city is the city of Yibin.
In the sixth year of Jianyuan (135 B.C.), Emperor Wu of Han Dynasty established Qianwei County, and at the beginning of the county administration, he (the west of Zunyi City, Guizhou Province) was established. In the first year of the first Yuan Dynasty of emperor Zhao of the Han Dynasty (86bc), Bodao city was transferred to Qianwei County, belonging to the History Department of Yizhou Prefecture in the Western Han Dynasty. Wang Mang established the "new" Dynasty in the first year (9th year) of the founding of the people's Republic of China. Qianwei county was renamed xishunjun county and Bodao county was renamed Bozhi. The county governance and leading County remained unchanged until the first year (23rd year) of the reform.
In the 12th year of Jianwu in the Eastern Han Dynasty (36th year), Qianwei County moved to Wuyang (Jiangkou Town, Pengshan County). Bodao county is still set up.
During the reign of Emperor Wu of the Southern Qi Dynasty (483-493), Qianwei County moved back to Bodao city from Wuyang. Until the second year of Jingming in the Northern Wei Dynasty (501), Bodao was occupied by "Yirong" and the county was abandoned. In 544, Emperor Wu of Liang Dynasty established Rongzhou in Bodao city after pacifying Yirong. The Northern Zhou Dynasty occupied Rongzhou in the first year of the Ming Dynasty (557 A.D.), and in the third year of Baoding (563), Waijiang county (governing Yibin City) was established in Bodao County, Rongzhou.
The Sui Dynasty replaced the Northern Zhou Dynasty in 581 ad. Yibin was occupied and Rongzhou was still established. In the third year of Daye of Sui Dynasty (607), Bodao city became the county of Qianwei for the third time until the early Tang Dynasty.
In 618, the first year of Wude, Emperor Gaozu of the Tang Dynasty, abolished sui qian as a county and established Rongzhou again. In the Tang Dynasty, Rongzhou was established for a long time until the end of the Tang Dynasty, except that it was renamed Nanxi County from the first year of Tianbao (742) to the first year of Qianyuan (758). In the period from the first year of Wude of Tang Dynasty to the sixth year of Zhenguan (618-632), it was in Fuxikou on the opposite bank of Lizhuang town in Cuiping District; the sixth year of Zhenguan to the first year of Changqing (632-821) was in Sanjiangkou of Yibin City; from the first year of Changqing to the first year of Huichang (821-841), it was in Fuxikou on the opposite bank of Lizhuang town. In 841, Rongzhou was located in Bodao city. In 842, due to the flood of Jinsha River, the state government moved from Sanjiangkou to jiuzhouba on the North Bank of Minjiang River until the end of Tang Dynasty.
In the Five Dynasties, Rongzhou and Bodao counties were still set up in the former Shu and the latter Shu, and the prefecture and county administration remained unchanged in Jiangbei.
In 965, the Song Dynasty occupied Rongzhou, which was still governed by Rongzhou, and Bodao county was still governed by jiuzhouba in Jiangbei. In 1114, Rongzhou was renamed Xuzhou and Bodao county was renamed Yibin County. Jiangbei Jiuzhou dam is still set up in the prefecture and county.

In 1281, Xuzhou was upgraded to Xuzhou Road, and Sanjiangkou city was established by Xuzhou Road and Yibin County. In addition, there were Xuanfu envoys of barbarians in Xunan and other places in the city, which were in charge of Xuzhou, Mahu Second Road, lawsuits of prefectures and counties, and 1000 household offices. Mingyuzhen, the leader of the red scarf army, became emperor in Chongqing in 1363, the 23rd year of Zhizheng reign of the Yuan Dynasty. After the occupation of Yibin, the military and civilian Xuanfu envoys of Xuzhou were set up in Yibin City of Sanjiangkou to manage the city area, and Yibin County was still established in the city.
