Where is the Hexi Corridor laid by Liu Che, Emperor of the Han Dynasty? How did they get their names?

The Hexi Corridor shot down by Emperor Wu of Han Dynasty is the hinterland of Gansu Province today. This corridor is a traffic artery connecting the mainland and the western region, and its strategic position is very prominent. Hexi Corridor is located in the Yellow River? What? On the west side of the glyph, from southeast to northwest, from Wushaoling in the east to Yumenguan in the west, it is more than 900 kilometers long and several kilometers to dozens of kilometers wide. There are Mongolian Plateau in the north, Qilian Mountain in the south, Loess Plateau in the east and quicksand in the west, so it is called Hexi Corridor, which is an important traffic lifeline of the ancient Silk Road.

Hexi Corridor, with its rivers and lush vegetation, is suitable for farming, and nomadic people occupied it long ago. If you don't take the Hexi Corridor, you have to take the Mongolian Plateau or the Qinghai-Tibet Plateau. Both plateaus are very difficult to walk and full of danger. Therefore, Hexi Corridor has become the traffic lifeline between the Central Plains and the Western Regions. Hexi Corridor in the Warring States Period belonged to Rong Di Department, and it belonged to Dayue Family in the Qin and Han Dynasties. At the beginning of Han Dynasty, Dayue was driven to the Western Regions by Xiongnu, and Hexi Corridor belonged to the left of Xiongnu. In order to attack the Huns from the east and west, Emperor Wu of the Han Dynasty sent Huo Qubing to open the Hexi Corridor. After two battles in Hexi, the Han Dynasty defeated the Xiongnu and brought the area under the direct rule of the Han Dynasty.

Hexi Corridor runs along Qilian Mountain, and the water source is all melted by snow from Qilian Mountain, so there is no corridor without Qilian Mountain. The mountains are covered with snow all year round, the slopes are covered with grass suitable for grazing, and the alluvial plain at the foot of the mountain is suitable for farming. The ecological conditions of the corridor are very similar to the Tarim Basin in Xinjiang. After the Han Dynasty occupied the Hexi Corridor, it could be controlled for a long time without losing. The main reason is that Hexi Corridor is suitable for farming, and the Central Plains people can take root after immigration. In the Han Dynasty, Wuwei County, Zhangye County, Jiuquan County and Dunhuang County were set up in Hexi Corridor thousands of miles away, and a large number of immigrants came to settle and defend the border.

In ancient times, there was only one corridor for Zhongyuan people to go to the western regions: the Mongolian plateau in the north was not controlled by the Central Plains regime and it was very dangerous to walk; Qilian Mountain in the south is more than 4000 meters above sea level. Crossing this mountain into the western regions is narrower than taking the Mongolian Plateau. Now the expressway has been completed and entered Xinjiang, and Lianhuo Expressway G30 is located in Hexi Corridor. This expressway can cross the Hexi Corridor in one day, but it took three months in ancient times.
