As we all know, Shanghai is the most prosperous city in China, and it is also the financial and economic center of China. Shanghai is located at the mouth of the Yangtze River in the east of China, bordering Zhejiang and Jiangsu provinces. But many people know that Shanghai was not an independent city before, but was managed by Jiangsu Province. Indeed, Shanghai used to be a small fishing village, which belonged to Songjiang Prefecture at that time. During the Qing Dynasty, Shanghai still belonged to Jiangsu Province, although it was not completely managed by Suzhou.
By the end of the Qing Dynasty, Shanghai, as an open port, attracted a large number of foreign capital into Shanghai, so Shanghai became the largest city in the Far East and a world-famous financial center. At that time, Shanghai's status improved a lot, so because of its unique geographical location, Shanghai became independent from Jiangsu Province and became a new city. Of course, Shanghai at this time is only separated from the main city of Jiangsu, and Baoshan, Jiading and Qingpu in the suburbs are still under the management of Jiangsu Province.
Later, these suburbs of Shanghai were zoned out from Jiangsu Province and distributed to Shanghai, such as Fengxian, Jinshan, Songjiang and Qingpu, which are all suburban counties of Shanghai and far away from Shanghai. But now with the opening of the subway line, it is more convenient for locals to go to Shanghai. This phenomenon is very common. For example, Hong Kong and Macau, two special administrative regions, used to be administered by Guangdong Province, and Taiwan Province Province also belonged to Fujian Province.
