The construction of Yichun City began in 20 1 year BC. Liu Bang, Emperor Gaozu of Han Dynasty, ordered all counties and cities to build cities, including Yichun and two cities built in Yichun today. The area under its jurisdiction is the urban area of Yuanhe River Basin, including Yuanzhou District, Xinyu City, Pingxiang City and Zhangshu City. In the first year of Jin Dakang (280), Emperor Wudi of Jin destroyed Wu, taking Yichun as the name, and having the same name as Zhang Chunhua, the empress dowager Xuanmu's grandmother and wife of Sima Yi. In order to avoid taboo, Yichun was changed to Yiyang. In the eighteenth year of Emperor Kai of Sui Dynasty (598), it was renamed Yichun. Chengjian County, a newly established county, is under the jurisdiction of Jinjiang River Basin, including Gao 'an City, shanggao county City, Yifeng County, Wanzai County and Zhangshu City. In the fifth year of Tang Wude (622), the county was renamed Gao 'an because of the same name as Prince Li. In the eighth year of Song Kaibao (975), Wanzai County was returned to Yunzhou. In the third year of Chunhua (992), a new metaphor was drawn into Linjiang Army. More than 900 years later, Yuanzhou successively took charge of Yichun, Pingxiang, Wanzai and Fenyi counties. In the next nearly 1000 years, Yichun once belonged to Yuanzhou, Ruizhou, Linjiang and Nanchang. It was not until the early years of the Republic of China that the first-level administrative institutions were abolished. 19 13, 10 In June, Jiangxi was divided into four roads: East Jiangxi, West Jiangxi, South Jiangxi and North Jiangxi, and the West Jiangxi Daozhi was located in Yichun County. Post-administrative areas change frequently. After liberation, the jurisdiction and administrative level of Yichun were adjusted several times, until May 22, 2000, Yichun area and county-level Yichun city were abolished and prefecture-level Yichun city was established. The Municipal People's Government is located in the newly established Yuanzhou District. Yichun City governs six counties, namely Yuanzhou, Fengxin, Jing 'an, Yifeng, Shanggao, Tonggu and Wanzai, and also administers Fengcheng, Zhangshu and Gao 'an. At this point, the reform of Yichun administrative divisions has been temporarily settled.
