Qinling Mountains:
There is an east-west mountain range in central China-Qinling Mountains. It is like a "wind wall", which blocks cold air from going south in winter and southeast monsoon from going north in summer.
Since ancient times, due to the special geographical environment in which the Qinling Mountains are located and the differences in climate change, cultural landscape and living customs between the north and the south of the Qinling Mountains, it has been called the dividing line between the north and the south of China. Traditionally, the south of Qinling Mountains is the south of China, and the north of Qinling Mountains is the north of China. However, the official name of Qinling Mountain began to exist only in the Han Dynasty.
The Qinling Mountains in a broad sense is a huge east-west mountain range across the central part of China, starting from Baishi Mountain in the north of Lintan County in Gansu Province in the west and bounded by Dieshan Mountain and Kunlun Mountain. Enter Shaanxi eastward through McKee in the south of Tianshui.
At the junction of Shaanxi and Henan, it is divided into three branches, the northern branch is Xiaoshan, and the remaining veins extend eastward along the south bank of the Yellow River, commonly known as Mangshan; The middle branch is Xiong 'er Mountain; The south branch is Funiu Mountain. A small part of the southern part of the mountain range extends from Shaanxi to Yunxian County, Hubei Province. The Qinling Mountains are 1600 kilometers long and tens of kilometers to two or three hundred kilometers wide from north to south. They cover a vast area and are magnificent.
In a narrow sense, Qinling refers to the middle part of Qinling, which is located in the middle of Shaanxi Province. It was called "Qinling Mountain" in the Han Dynasty, and it was named "Nanshan" because it was located in the south of Guanzhong.
Huaihe River:
Huaihe River, east of Qinling Mountains, is a big river in China, with a total length of 1 252km, which originates from Tongbai Mountain, Tongbai County, Henan Province. It is worth mentioning that the differences in topography, rivers and hydrological characteristics between the two sides of the Huaihe River are not as obvious as those between the north and the south of the Qinling Mountains. To a great extent, the Huaihe River as a dividing line between the north and the south is mainly based on the significance of its geographical division.
China's National Geographic magazine once wrote that "Huaihe River can't find its own home", which is precisely the reason. Seeing the Huaihe River as a part of the north-south dividing line of China should also bring understanding, and should not be confined to a specific river system, which is also related to the actual river basin of the Huaihe River.
