Inner Mongolian Plateau
China DailyThe Inner Mongolian Plateau, the second-largest plateau in China, is known for its vast and flat landscape. This region features ancient structures like the Great Wall from the Qin and Han dynasties, the Great Wall of the Six Frontier Towns erected during the Northern Wei Dynasty, and the Tang Dynasty's "Shouxiang City" fortresses, which are critical military defense cities in the Hetao region. This fortunate accident, triggered by a simple pen slip, gradually revealed the mysterious secrets of the Juyan Han Great Wall, providing invaluable evidence for the study of the Han Dynasty's border defense system. The Tang Dynasty built three key military fortresses known as "Shouxiang City" along the Qin and Han Great Wall. In Inner Mongolia, this part of the Jin Dynasty's Great Wall became known locally as the "Genghis Khan Border Wall."
