Some time ago, Xi'an was soaked in heavy rain, and successive rainy days seemed to be soaked in rain. The sky in the suburbs seemed particularly clean after the rain, and the wonders of clouds crossing the Qinling Mountains also appeared. Lu You, a poet in the Tang Dynasty, once wrote,"Where is the Yunzhong home in the Qinling Mountains, and the snow embraces the Blue Pass and the horse does not move forward." Across thousands of years, this scene has finally appeared in front of Xi'an citizens. Standing at a high place, you can clearly see the Qinling Mountains. The mountains after the rain are surrounded by clouds of clouds, and the green mountains are like shadows and lines that are amazing.

Geographers believe that China's mountains are rooted in Kunlun, and before Qin unified the six countries, the Qinling Mountains were Kunlun. Later, because they stood in the southern part of Qin, they were also called Nanshan or Zhongnan Mountain. In reality, the Qinling Mountains are located in the central part of our country, and together with the Huaihe River, are called the north-south dividing line. In the novel, the Qinling Mountains are the location of the dragon vein and are full of mystery. The mountain range stretches for more than 1600 kilometers from west to east and originates from the Kunlun Mountains. The endless mountains are naturally rich in forest resources. There are more than 1119 kinds of Chinese herbal medicines alone, as well as various woody plants and rare plants. There are also many animal species, including not only the precious giant panda but also the rare golden monkey. There are also more than 80 wild protected animals and more than 300 birds. It is truly a kingdom of animals and plants. This is an undeveloped virgin forest and a little-known paradise. With her broad mind, Qinling Mountains embraces all things in the world and also breeds a different kind of natural scenery.

In winter, the Guanzhong area north of the Qinling Mountains is windy and snowy. People must hold stoves and guard the hot kang to survive the winter smoothly. However, south of the Qinling Mountains is another scene. The Sichuan Basin is full of spring and flowers. How amazing that a mountain range can change the natural pattern. With the Qinling Mountains, China has north and south, and there is a strong difference between north and south. From the changes in tastes to the differences in styles between the north and the south, whether it is the gentleness of the south or the boldness of the north, they are all closely related to her. Because of the natural barrier of the Qinling Mountains, the wind and rain of the eight hundred miles of Qinchuan River have been smooth.

This was also a military location that could not be ignored in ancient military affairs. In order to make it easier to cross the Qinling Mountains, the ancients went to great lengths and opened up countless channels here. You can imagine how difficult it was to open mountains and cultivate cultivation in the towering Qinling Mountains with the technical conditions at that time. The famous historical allusion "Ming Xiu Plank Road secretly depicts Chencang" is that Liu Bang used to build a plank road to confuse Xiang Yu at that time, but he led his men to leave Shu on Chencang Road. This Chencang Road is the most famous of the six plank roads in the Qinling Mountains.

In short, whether it is the unique geographical location, the superior geographical environment, or the various events and allusions in legends in history, they all tell future generations the mystery of the eight hundred miles of Qinchuan River. This majestic mountain range spans ancient and modern times, standing tall and stretching on the dividing line between the north and south of our country. Its vast momentum and grandeur make it impossible for people to recognize its original appearance, but it just surrounds infinite resources and gifts to mankind. Moreover, as an important natural ecological barrier in my country, the Qinling Mountains play a key and important role in conserving water and soil, regulating climate, and maintaining ecological diversity. Therefore, we should protect these green waters and green mountains.
