Geomantic omen in Gobi desert
It was not easy for ancient people to do business. In order to maximize the benefits, they have to pass through Jiayuguan. These businessmen have to cross desert after desert if they want to do business in Xinjiang and other places. There were no motor vehicles at that time, so once you get lost in the desert, you basically risk your life. There are also many bandits robbing these businessmen in the desert. Therefore, the surviving businessmen told their stories to the people. As soon as the folk spread, the story behind Jiayuguan appeared, which is the saying of the gate of hell.
Second, it implies that the back of Jiayuguan is not an environment where human beings can live normally.
Behind Jiayuguan, most of them are desert areas. Speaking of desert, you will definitely think that without any plant cover, the annual precipitation is equal to nothing. What is even more frightening is that as long as it is a desert area, the wind and sand are particularly heavy. Therefore, pedestrians can't walk normally, even if they can, they can't keep their eyes open. At that time, there was a song describing this situation:
Out of Jiayuguan, my tears stopped. Looking ahead, Gobi desert; Look back, the gates of hell. Out of Jiayuguan, my tears stopped. Look up at the gray sky and look down at the Gobi Desert. Out of Jiayuguan, tears can't be wiped away ...
This song is what people saw when they walked out of Jiayuguan. It can be seen that the desert area at that time was as bad as the desert area now, and people could not survive, so Jiayuguan was the gate of hell.
Of course, that was in ancient times. After all, people at that time were not productive enough and feudal superstitious. Now there is an expressway in Jiayuguan, and there are more people living there. Few people say that there is a gate of hell behind Jiayuguan.
