Jiayuguan, built more than 600 years ago, as a necessary pass on the ancient Silk Road, is the starting point of the western end of the Great Wall in the Ming Dynasty. At present, it is also a national key cultural relics protection unit and world cultural heritage.
        Go up the steps and climb to Jiayuguan. You can see that there is a city in the city, a wall outside the city and a trench outside the wall. Looking up from afar, the Qilian Mountains are endless, and the Hexi Corridor is green.
        When people talk about China, they will think of the Great Wall. Jiayuguan, known as "The Impregnable Jiayuanguan Pass in the World", is also the concentrated embodiment of the Chinese nation's protection of Xinjiang and soil and the pursuit of peace.
