What area does "Jiangdong" mean?

That is, southern Anhui, southern Jiangsu, central Jiangsu, Zhejiang, northeastern Jiangxi and Shanghai are called Jiangdong.

Because the Yangtze River flows obliquely to the northeast in southern Anhui today, the east, west and left are determined according to this section of the river. Jiangdong refers to the area south of the Yangtze River.

During the Qin and Han Dynasties, Anhui was divided into two banks of the Yangtze River, and Jiangbei was also called Jiangxi. (During the Three Kingdoms period, some Jiangbei areas belonged to six counties in Jiangdong)

During the Tang and Song Dynasties, Jiangsu, Anhui, Zhejiang and Shanghai, south of the Yangtze River, were the road to Zhejiang, with Xin 'anjiang as the boundary, which was divided into two roads: east and west. Jiangdong (Jiangnan East Road) in the Song Dynasty refers to southern Anhui, eastern Jiangxi and jiangning house, and Liangzhe Road in the Song Dynasty refers to southern Jiangsu, Zhejiang, southern Anhui and Shanghai.

In the Qing Dynasty, Jiangdong was also called Jiangzuo, and Jiangxi was also called Jiangyou. That is, southern Anhui, southern Jiangsu, central Jiangsu, Zhejiang, northeastern Jiangxi and Shanghai are called Jiangdong.

Extended data:

In the Three Kingdoms, Jiangdong refers to six counties in Jiangdong.

Specifically, it refers to: Wu Jun (Suzhou City, Jiangsu Province), Huiji County (Shaoxing City, Zhejiang Province), Danyang County (Wanling County was first administered by the county and later moved to Jianye City, Jiangsu Province), Zhang Yu County (Nanchang City, Jiangxi Province), Luling County (northwest of Taihe County, Jiangxi Province) and Lujiang County (west of Lujiang County, Jiangxi Province).

At the end of the Eastern Han Dynasty, warlords scuffled, and Wu Jun Fuchun, Sun Shi, and Sun Jian were promoted to Changsha magistrate and became the leaders of the separatist regime because of suppressing the Yellow turban insurrectionary uprising. Sun Jian's eldest son, Sun Ce, is young and promising. He led his father more than a thousand people, crossed the river to pacify Jiangdong, occupied six counties in Jiangdong, and was named Wuhou.

Sun Jian's second son, Sun Quan, inherited the legacy of his father and brother, and with the support of Zhou Yu, Zhang Zhao and other aristocratic men, he stabilized the situation in Jiangdong, defeated Cao Cao and Liu Bei, proclaimed himself emperor in 229 AD, and became the kingdom of Wu among the three pillars.

Jiangdongye (the jurisdiction of Ningbo City) refers to Yinzhou District with a long history. As early as the Neolithic matriarchal clan commune, there were primitive people living in the territory.

1973 The original commune site was discovered in Lujiaqiao, Sanlian Village, Sanjiao Township, with a history of 5,000 years, and its cultural age is equivalent to the second floor of Hemudu Culture.

At the end of primitive society, at the latest in early summer, "Yin" has become a definite place name, and Yin is composed of the words "purple" and "city". Gu Zuyu summed up the public opinion in Reading History: "There is a country of violets in summer, named Red Violet Mountain ... and Jiaxu is cloudy."

Red pansy mountain, or pansy mountain, is located in Baidu, Fenghua today. Yinxian belonged to Yue State in the Spring and Autumn Period and Chu State in the Warring States Period. In 222 BC, Qin destroyed Chu and established Yin, Zhi and San Counties. The Han dynasty attacked the Qin system and still set up three counties.

In the Eastern Jin Dynasty, Emperor Wu of Song defended the punishment and built a new city in Xiaoxi Town (now Yinjiang Town). In the third year of Sui Dynasty, all counties were unified and collectively called Zhang Ju County. In the Tang dynasty, it was changed to magistrate of a county. At the beginning of the Five Dynasties, it was changed to Yinxian, and the name of Yinxian has been used ever since.

In the Northern Song Dynasty, Yin County was divided into six townships, either located in Guo Chang County (now Dinghai District of Zhoushan City) or designated as Dinghai County (now Zhenhai and Beilun District of Ningbo City), and the county territory remained stable since then.

In the past, Ningbo was ruled by Yin County, formerly known as Mingzhou, but renamed Ningbo in the Ming Dynasty because of taboos. After liberation, Ningbo was divided into cities and Yinxian was successively under the jurisdiction of Ningbo District (region) and Ningbo City.

On April 9, 2002 19, it was established as Yinzhou District of Ningbo City with the approval of the State Council. 201June September 14 With the approval of the State Council, the administrative area formerly under the jurisdiction of jiangdong district was placed under the jurisdiction of Yinzhou District of Ningbo City.
