#I really want to go out to play Jiayuguan: The ancients built a city with loess 600 years ago, which is an important transportation hub of the Silk Road and is known as the first pass in the world! Jiayuguan, known as the "first Xiongguan in the world", is located in the middle of the narrowest valley 5 kilometers west of Jiayuguan City, Gansu Province. The walls on both sides of Chengguan cross the desert Gobi, the Great Wall of Montenegro in the north, and the first pier in the south. It is the westernmost gate of the Great Wall of Ming Dynasty. It has been known as Hexi throat in history. Due to the danger of the terrain, the building is majestic, and it is known as the key of the lock. Jiayuguan is a traffic fortress of the ancient "Silk Road", one of the three wonders of the Great Wall of China (Shanhaiguan in the east, Beitai in the town, and Jiayuguan in the west). Jiayuguan was built in Minghongwu five years (1372), composed of the inner city, outer city, Luocheng, Yucheng, Chenghuang and the north and south wings of the Great Wall, the total length of about 60 kilometers. The Great Wall, Duntai, and Fort City are scattered, and the three defense lines of the inner city, the outer city, and the city are overlapping and guarding, forming a defense system of five miles, ten miles, one pier, thirty miles, and one castle. Jiayuguan is a world cultural heritage, national AAAAA-level tourist attraction, national key cultural relics protection units, and a national demonstration base for patriotic education. The main attractions are Jiayuguan Guancheng, Suspension Wall Great Wall, Great Wall First Dun, Weijin Tombs, Black Mountain Stone Carvings, Mulan City, "Seven·One" Glacier, Gliding Base, etc. Jiayuguan, built in Minghongwu five years (1372), nine years earlier than Shanhaiguan, is the largest pass on the existing Great Wall, but also the largest pass in China. Before Song and Yuan, Jiayu area related to no city, only to check the role of pedestrians. In the Ming Dynasty, in order to strengthen the northwest border defense, Song Guogong Feng Sheng decided to build Guancheng here. Soon, Jiuyan Spring area flatly rose a loess city, with a circumference of 220 feet, two feet high and one foot wide. This is the earliest prototype of Jiayu Xiongguan. Turpan in the west of the Ming Dynasty was becoming stronger, often attracting troops into the cities of the Hexi Corridor, and the Jiayu Mountain Pass was a must-pass place. Since the completion of Jiayuguan, this gate has been a major national defense area in the west, playing an important role in ensuring the security of the Hexi area. Since then, Ming Xiaozong built a Guanlou. During the Zhengde period, the second floor of the east and west, namely the Guanghua Building and the Rouyuan Building, Jiajing reinforced the existing building and built the two wings of Guancheng Great Wall, and set up a pier every five miles. From the beginning of Ming Hongwu's five years (1372), to the 18th year of Ming Jiajing (1539), Shangshuxuan reinforced Guancheng, built two wings of the Great Wall, Jiayuguan intermittently built 168 years, becoming a more complete defense castle. #My aerial film #Check in movie location
