From a historical perspective, Yanmen Pass has served as a crucial hub for exchanges between the Central Plains and the nomadic ethnic groups of the north since the Spring and Autumn Period. It has witnessed countless wars and historical events, such as the story of the Yang Family Generals and the Journey to the Frontier by Concubine Zhaojun, making it a symbol of the Chinese national spirit. Its well-preserved city walls, fire towers, arrow towers, and other military installations, along with its rich historical relics, allow visitors to deeply experience the grandeur and splendor of ancient frontier defense culture.
