Nanjing is surrounded by Anhui Province on three sides except the east. The real main city is Linjiang in the west and Baohua Mountain in the east. The real hinterland is only Jiangning. The way to increase the area is to use Zhenjiang to get back the original sentence.
The geographical feature of Nanjing is that it is long from north to south and narrow from east to west, a bit like a seahorse. The last time Nanjing annexed the surrounding territories was in 1983, when Lishui and Gaochun counties in Zhenjiang were incorporated into the territory of Nanjing. The last large-scale internal withdrawal of counties and districts was in the early 20th century (2 1). In 2000, Jiangning was divided into districts from counties. In 2002, Jiangpu County and Liuhe County merged into Xinpukou District and Liuhe District.
The expansion of regional scale is also an important means to enhance the city's primacy. For a long time, Nanjing has lagged behind Suzhou, Wuxi and Changzhou in economic aggregate, and is known as Su Xiaosan in the province. Moreover, Nanjing does not belong to the Wu dialect area, and its territory is embedded in Anhui Province. For a long time, the status of the provincial capital is not high.
The origin of place names
In the past, there were administrative organizations at different levels, such as cities, counties, prefectures, counties, capitals, special cities, municipalities directly under the central government, provincial capitals, cities with separate plans, and sub-provincial cities. There are many names of Nanjing, which are rare not only in China, but also in the world.
The official names specified in the official names are Jinling, Moling, Jiangcheng, Hushu, Jianye, Shicheng, Yangzhou, Danyang, Jiangning, Jianye, Jiankang, Jincheng, Jiangzhou, Shengzhou, Guihua, Baixia, Shangyuan, Xi Du, Liudu, Peidu, Qing Ji and Yingtian.
There are more than 40 folk customary titles such as Yecheng, Yuecheng, Huju Longpan, Huangyi, Shenjing, Guoshang, Shangjing, Jiangnan Kerry Land, Jingyi, Baimen, Huang Du, Jason Wu, Dili, Jiangnan First State, Jiangcheng, Southland, Hangdu, Nanzhong, Southland, Xindu, Xinjing, Qinhuai and Zhongshan.
The change of organizational system and the diversity of names reflect the ups and downs of Nanjing's historical development. In the 28th year of Yuan Dynasty, Zhu Yuanzhang proclaimed himself emperor in Yingtianfu, with the title of Daming, and set up Nanjing in Yingtianfu, which was the beginning of the place name "Nanjing".
