There are hundreds of Han tombs at the foot of the mountain, such as hills, the highest is about 15 meters, and the lowest is about 4 meters. They have been scattered in the wilderness until now. In these Han tombs, there are countless loyal ministers who guarded Yanmenguan in the Han Dynasty. Pedestrians passing by here are all in awe. Walking out of the foggy city and along the same road, you will enter a narrow valley, which is called the Yanmen Ancient Road. On both sides, there are mountains and peaks, and strange rocks are dangerous. When you cross a steep ridge, Yanmenguan will jump into people's eyes.
Yanmenguan borders Longling and Yanmen Mountain in the east and Longshan in the west. The two mountains are opposite, like a noisy door. Wild geese fly in it every year, so it's called the Wild Goose Gate. During the Spring and Autumn Period and the Warring States Period, King Wuling of Zhao set up Yanmen County here. In the Tang Dynasty, it was named Xi's Hydrocarbon Pass, also known as Yanmenguan. ; Jujube is located on Yanmen Mountain on the west side of Yanmenguan. In the seventh year of Hongwu in Ming Dynasty (A.D. 1374), Hou Luting of Ji 'an moved Guancheng here and rebuilt Guancheng. The Guancheng of Yanmenguan has a circumference of two miles, the wall is one foot eight high, and the stone foundation: there are three gates and city bricks. There is a balcony above the east gate, called Yanlou, with a stone plaque embedded in the doorway and a book called "Natural Barrier".
Yang Liulang Temple was built on the west gate, with a stone tablet embedded in the door, and the book says "geographical location". There is no roof in the north gate, and a stone tablet is embedded in the door. The book reads "Yanmenguan" in three big characters, and a pair of couplets are engraved on the left and right: "Three customs are unparalleled, and Jiuzhai respects the first customs." There are military camps in the north and Jingbian Temple in the east. There are a pair of stone lions, a vertical flagpole and a stone tablet in it. The inscription describes the great achievements of Li Mu, a famous soldier of Zhao, who led the army to fight the Huns many times. Southeast: There is a training school in the direction.
Yanmenguan, Ning Wuguan and Piantouguan are the "outer three passes" of the Inner Great Wall. Here the peaks are stacked, the cliffs are steep, and the walls are densely covered with spies. From a distance, the monkeys echo each other. The east and west sides connect Laoyingkou with Shenchiguan, Yangfangkou, Donglongkou, Xihekou and Bilouguan. Eighteen passes, such as Dashikou, Shikou, Malankou, Ruyuekou and Huyukou, are connected as a whole, and the terrain is very dangerous, which has become a battleground for military strategists in past dynasties.
