South refers to the area south of Huaihe River in Qinling Mountains and east of Qinghai-Tibet Plateau, and often refers to the area south of specific or implied azimuth points. In China, "southern region" generally refers to the vast area south of the Qinling-Huaihe line. We can distinguish whether Nanjing belongs to the south or the north from the relative position of Nanjing and Huaihe River.
Nanjing is located in the east of China, in the middle of the lower reaches of the Yangtze River. It is an important national gateway city driven by radiation in the Yangtze River Delta. Its geographical coordinates are 3 1 14 "north latitude to 32 37" east longitude 1 18 22 ". ? The geographical coordinates of Xinjiekou in the city center are 32 02' 38 "north latitude and118 46' 43" east longitude.
Huaihe River Basin is located in the east of China, between the Yangtze River and the Yellow River, with a latitude of 30 55' ~ 36 36' north latitude, which is the same as that of Nanjing, and about 33 north latitude. The dimension of Nanjing is lower than that of Huaihe River, and it is south of Huaihe River, so Nanjing belongs to the south.

The importance of Nanjing's geographical location in history
Historically, Nanjing has benefited and suffered from its unique geographical location and extraordinary geomantic scenery. In the past, Nanjing suffered many military disasters, but it also rebuilt its prosperity from the ruins many times. When China was occupied by foreigners and the Han nationality was about to suffer extinction, the Han nationality usually chose Nanjing to recuperate and aspire to the Northern Expedition and restore China.
Daming and the success of the second Northern Expedition in the Republic of China; In the Eastern Jin Dynasty, Xiao Liang and Liu Song were defeated in the Northern Expedition. At the beginning of the Southern Song Dynasty, all the ministers talked about taking Jiankang as the capital to restore the Central Plains. They regretted that Song Gaozong had no intention of the Northern Expedition and decided to go to Lin 'an, but forced by public opinion, they decided to make Jinling the capital. The Taiping Heavenly Kingdom takes Nanjing as its capital, and it also takes the expulsion of alien rule as one of its mobilization bases and legitimacy.
Therefore, Nanjing is regarded as the revival place of the Han nationality and has a special position and value in the history of China. Therefore, after comparing the four ancient capitals of Chang 'an, Luoyang, Jinling and Yanjing, Mr. Zhu Dai said: "These four metropolitan cities are rich in literature, handsome in people, beautiful in mountains and rivers and magnificent in weather, which is closely related to the national crisis, especially Jinling."
