In which year did a large number of people move into Tongling, Anhui?

Anhui and Jiangsu once belonged to South Zhili and jiangnan province in history. Judging from the historical evolution of Anhui and Jiangsu provinces, Anhui and Jiangsu can be described as "twin brothers".

During the Qianlong period of the Qing Dynasty, Anhui and Jiangsu were separated. Jiangsu uses the initials of jiangning house and Suzhou to synthesize "Jiangsu", while Anhui uses the initials of Anqing and Huizhou to synthesize "Anhui".

The administrative divisions of Anhui and Jiangsu were basically stable after liberation. 1955 In March, in order to facilitate the management of Hongze Lake, the administrative divisions of Anhui and Jiangsu were changed with the consent of the state, that is, Xuyi County and Sihong County, which originally belonged to Anhui Province, were placed under the jurisdiction of Jiangsu Province, and Xiaoxian County and Dangshan County were placed under the jurisdiction of Anhui Province.

On the surface, although only the four counties changed across provinces, it affected the administrative divisions of the two provinces to some extent.

Because Sihong and Xuyi were drawn, Sihong, Xuyi and Tianchang were broken as a whole, and Tianchang was surrounded by Jiangsu on three sides, just like a "fist" entering the hinterland of Jiangsu, which always made people feel uncomfortable.
