There are three Yumen Pass, namely Yumen Pass in the Western Han Dynasty, Yumen Pass in the Sui and Tang Dynasties and Jiayuguan Pass. One of them, Yumenguan, has been flooded due to disrepair, and the other two still exist. Now Jiayuguan has become a famous scenic spot in China, and tourists come and go every year. For a place in Yumenguan, it not only has historical research value, but also has tourism appreciation value.

Whether from the historical role or from the present, Jiayuguan was an iron wall in ancient times, resisting foreign invasion and closing the door to cultural exchanges with other countries and tribes. It opened the door to China culture and showed the color of China to the world. Zhang Qian, the most famous emissary of the Western Regions in history, walked out from here. Although it is remote and located in Gansu, it is also the most well-preserved historical relic with the most historical research value, and now it belongs to world-class heritage.

In fact, Jiayuguan is a part of the Great Wall, which was established during the Qin Shihuang period. It can be seen that it has a long history and is a very powerful military defense system in history. It can be said that it can be attacked and defended, and every door on Jiayuguan has its special significance. The east gate is called. Gwanghwamun? At that time, the original intention of the establishment was that the purple gas came from the east and shone brilliantly. What's Simon's name Rouyuan? It means to come from Huairou, so as to settle the west.

It can be seen that Jiayuguan is magnificent as a whole from a distance and looks like an independent landscape in the desert. Among many historical sites, Jiayuguan is relatively well preserved, so now as a tourist attraction, it attracts many people from home and abroad to witness its elegance. It still shows its sacred and inviolable posture with its tall and straight posture.
