Ezhou has a history of nearly three thousand years since it was called "E" in the Western Zhou Dynasty. In the middle of the Western Zhou Dynasty, Hubei was originally located in the northern part of Nanyang, Henan Province, and was called western Hubei. The royal family of Hubei rebelled against the Zhou Dynasty, "led the south and the east to attack the south and the east", and occupied Yang Yue, known as the east of Hubei, and ruled this land. This is the beginning of the local name "e" In the seventh year (863 BC), Xiong cut in the canal. As for Hubei, Xiong Hong was named King of Hubei. At that time, the king of Hubei took Ezhou as the political and economic center, and his territory almost covered the whole southern Hubei area. Hubei's land was later called Hubei City, which ruled here today and was once another capital of Chu State. During the Spring and Autumn Period, E-Yi Institute was still regarded as the "other capital", and Hubei was an important copper base in Chu. During the Warring States Period, E-Yi was once the fief of E-Jun-Qi, and it was valued by the State of Chu because of its special strategic and economic status.

In the twenty-fourth year of the King of Qin (223 BC), Qin destroyed Chu, and Hubei belonged to Qinnan County (Nanjun is now Jingzhou). In the twenty-sixth year (22 1 BC), Qin Shihuang unified the whole country, and the local area was Hubei County, which was still under the jurisdiction of Nanjun County. The county is located in the east of Ezhou city today. Hubei has some cities and counties such as Ezhou, Huangshi, Daye, Xianning, Jiayu, Puyin, Chongyang and Tongshan, and Wuchang District and Jiangxia District of Wuhan. In the Han Dynasty, Hubei County belonged to Jiangxia County of Jingzhou and Anlu County (now Yunmeng, Hubei Province). In the early years of the Western Han Dynasty, Shaxian County (now Wuchang District of Wuhan City) and Xialuo County (now southeast of Yangxin) were enfeoffed to Hubei County. Hubei county, which is divided into counties, ranks seventh among the 14 counties headed by Jiangxia county. In the Eastern Han Dynasty, it ranked eleventh. The territory of Han 'e County includes Ezhou, Huangshi and Dazhi, and the part of Yangxin County north of Fushui.

When the Three Kingdoms were separated, Sun Quan moved from the police to Hubei County in the second year of Wei Huang (22 1), and changed Hubei County to Wuchang County, which was the beginning of the local name "Wuchang". Wuchang county has about three cities: Ezhou, Huangshi and Daye. Wuchang County is located in Wuchang County, which governs Wuchang, Jiangxia, Shaxian, Charlotte, Xingguo, Chaisang (southwest of Jiujiang) and Xunyang (Jiujiang). County governance, county governance are all in this city. In April of the first year of Wu Huanglong (229), Sun Quan proclaimed himself emperor in Wuchang. Since then, Wuchang is not only the seat of the county, but also the capital of Sun Wu and the political center of Jiangnan. The ruins of the capital are still visible.

In the Western Jin Dynasty, the local government was still Wuchang County, first Jingzhou and then Jiangzhou. At that time, Xunyang County and Chaisang County, which belonged to Wuchang County, were separated and merged into Xunyang County. In the first year of Taikang in the Western Jin Dynasty (280), Wuchang County was divided into Wuchang County and Hubei County, Hubei County was located in Xifan, daye city, and the two counties belonged to Wuchang County in Jingzhou. In the first year of Yuankang (29 1), Wuchang County belonged to Jiangzhou. In the first year of Jianwu in the Eastern Jin Dynasty (3 17), Jiangzhou was located in Wuchang (now Ezhou).

During the Southern Dynasties, the territory and county governments of Song, Qi, Liang, Wuchang and Hubei remained unchanged. In Liu Song Dynasty, Wuchang County was changed from Jiangzhou to Yunzhou. The state capital is located in Xiakou (now Wuchang District, Wuhan). Wuchang's once important position was gradually replaced by Xiakou. Although the Wuchang is still governed by one county, its territory is gradually shrinking. By the time of Chen (557-589), the two counties were divided into Wuchang and Xiling counties in Hubei Province, which belonged to Wuchang County in northern New South Wales. The county seat is in Wuchang (now Ezhou) and Xiling is in Huangshi.

In the ninth year of Huang Kai (589), the word "E" was changed to Ezhou, which was located in Xiakou (now Wuchang District of Wuhan), which was the beginning of the westward movement of the word "E". In the same year, Wuchang County was abolished, and Hubei and Xiling entered Wuchang County, belonging to Ezhou. In the first year of Tang Yuanhe (806), Ezhou established a military organization named Wuchang Army, and its military headquarters was located in Xiakou (now Wuchang District of Wuhan), which was the beginning of the westward movement of the name Wuchang. At that time, the local area was Wuchang County. At this time, Wuchang Military City and Wuchang County both existed. Therefore, Liu Changqing, a poet in the Tang Dynasty, wrote the phrase "Go up and down Wuchang City". During the Five Dynasties (907-960), Wuchang County was successively subordinate to Wu Yang Ezhou and Nantang Ezhou. In the seventh year of Li Yu in the Southern Tang Dynasty (967), Daye County was established in the land of three townships in Wuchang County (including today's Huangshi City), and both Wuchang County and Daye County were subordinate to Ezhou. Wuchang county, east to Mount Cisse, south to Damu, west to Liangzi Lake and north to the Yangtze River.

In the eighth year of Kaibao in the Northern Song Dynasty (975), Wuchang County was subordinate to Ezhou (Jiangxia County) on Jinghu North Road. In the 14th year of Jiading in the Southern Song Dynasty (122 1), Wuchang County was promoted to Wuchang Army. Because its name is similar to that of Wuchang Army in Ezhou, it was named "Yubao Shou Chang", and the following year it was renamed Shouchangjun, commanding Wuchang County. This is the beginning of the local name "Shou Chang". In the first year of Duanping (1234), Shouchangjun was abolished and Wuchang County was subordinate to Ezhou (Jiangxia County). In the first year of Jiaxi (1237), Wuchang County was promoted to Shouchang Army again, and the Wuchang Army in Zhili was saved. In the 14th year of Yuan Dynasty (1277), Shouchang County was renamed Wuchang Sanfu, which belonged to Ezhou Road. In the fifth year of Yuan Chengzong Dade (130 1), Ezhou Road was renamed Wuchang Road, and the administrative office was located in Xiakou (now Wuchang District, Wuhan). The name of "Wuchang" moved westward was changed from the name of military establishment to the name of administrative division. At this time, Wuchang County belongs to Hubei Road Wuchang Road. In the 24th year of Zheng Zhi, Yuan Shundi (1346), Wuchang Road was changed to Wuchang House, and Wuchang County was subordinate to Wuchang House. In the first year of Hongwu in Ming Dynasty (1368), Wuchang County belonged to Wuchang House, the chief secretary of Huguang, and Cisai Mountain belonged to Daye County. In the third year of Emperor Kangxi of Qing Dynasty (1664), Wuchang County belonged to Wuchang House, Yanfa Road, Wuchang, Hubei Province. In Qing Dynasty, the banks of Changgang, Luzhou and Shipu from Fankou to Luxikou (60) were classified as Huangzhou weitun. Moon Mountain is a Daye enclave.

In the second year of the Republic of China (19 13), Wuchang House was abolished and Jiangxia County was changed to Wuchang County, but Wuchang County was renamed Shou Chang County. Up to now, the word "Wuchang" in 1692 has been used locally and replaced by Jiangxia. The following year (19 14), Shou Chang county was renamed as Sun Yicheng county (named Sun Yicheng because there was a royal city in China) because "Shou Chang" had the same name as Xijiang county. This is the beginning of the local name "Sun Yicheng". The territory of Sun Yicheng County has not changed, and it still belongs to Erdong Road in Hubei. 193 1 year, Sun Yicheng County is under Jianghan Road, Hubei Province. 1932, Sun Yicheng county was under the second administrative supervision area of Hubei province (southern Hubei administrative office). From 65438 to 0936, Sun Yicheng County was under the jurisdiction of the First Administrative Supervision District of Hubei Province (East Hubei Administrative Office).

During the period of 1953, Sun Yicheng County belongs to Huanggang District, Gao Qiao District of Sun Yicheng County belongs to Xianning, and Baisha Township belongs to Huangshi. 1955, Gongyan District and Jinniu Town in Tanqiao District of Sun Yicheng County belong to Daye County, while Tingzu and Bishidu in Daye County belong to Sun Yicheng County. 1960, Wuchang county government moved out of fujiapo, Wuchang District, Wuhan, and moved into a paper mill. It was not until 1994 that the county was changed to Jiangxia District, which belongs to Wuhan City. The word "Wuchang" in Wuchang District of Wuhan City has been in use ever since. Because Wuchang, the capital of the Qing Dynasty, was the seat of Ezhou before the Yuan Dynasty, the word "E" became the abbreviation of Hubei Province. 1960, Sun Yicheng withdrew from the county to build the city. 1962, Sun Yicheng withdrew from the city and resumed the county. 1965, Sun Yicheng county belongs to Xianning area. From 1979 to 12, Hubei was assigned to Huanggang, and the counties and cities were divided. Sun Yicheng county has jurisdiction over 24 rural people's communes and Changgang farms, while Sun Yicheng has jurisdiction over Gu Lou and Fankou sub-district offices and Shishan people's commune. 1983, with the approval of the State Council, Hubei Province merged Hubei County, Hubei City and Huangzhou Town of Huanggang County, and took the word "E" in Hubei City and "Zhou" in Huangzhou County to establish Ezhou City, which was under the jurisdiction of Hubei Province. The city name "Ezhou" coincides with the "Ezhou" established in the ninth year of Emperor Kai of Sui Dynasty (589) (the administrative office is located in Wuchang District, Wuhan). From 65438 to 0986, Zuo Ling Town of Ezhou City belonged to Hongshan District of Wuhan City. From 65438 to 0987, Huangzhou District of Ezhou City was subordinate to Huanggang County, and its organizational system was divided into three county-level districts, namely Sun Yicheng, Huarong and Liangzihu, and a deputy county-level unit, Changgang Farm.
