Open this door and meet the most beautiful Jiayu pass. Have you ever seen such a great wall? The snow capped South Mountain in the south is called Qilian Mountain, and the black and shiny North Mountain in the north is called Heishan. The city between the two mountains is called Jiayuguan. If the head is compared to Jiayuanguan Pass, the left arm is the Great Wall pier, and the right arm is the Overhanging Great Wall.

In 1539,
Zhai Luan, then Minister of military affairs of the Ming Dynasty, inspected Hexi defense,
Seeing that the defense system of Jiayuguan is imperfect,
Therefore, the imperial court was prepared by the soldiers of Suzhou and Li Han
Supervised the construction of the Great Wall on the north and South wings,
Today's open and dark walls,
The open wall is the first pier that ends at Guannan TaoLai river,
The hidden wall ends at the Overhanging Great Wall at the mouth of Shiguan gorge in Guanbei.

In order to facilitate visitors to climb,
When it was rebuilt in 1987,
A stepped manway was also built on the first pier and the wall of the ridge city.

Up the road,
Although there are only more than 400 steps,
But it's enough to make people hesitate,
But as long as you get to the top of the mountain,
Looking around,
A panoramic view of the desolation of the desert outside the pass,
Only a few oases dotted it,
It shows that there is still life and harsh natural environment here
Fight tenaciously.

From south to north,
The first beacon tower at the westernmost end of the Great Wall in the Ming Dynasty - "the first pier in the world"
he Impregnable Jiayuanguan Pass in the World-- Jiayuguan
"The great wall hangs upside down and the iron arm hangs in the air" -- Overhanging Great Wall
Together, it forms a complete military defense system at Jiayuguan,
The North-South span is more than 15 kilometers.
