The Copper Column of Xizhou is in Yongshun County, Hunan Province.

The column used to stand on the bank of the Youshui River, near Yejituo Village, Yongshun County, Hunan Province. In 1971, because of the construction of the Fengtan Reservoir, it was moved onto Huaguo Mountain in the Wangcun Village, about 10 km south of the original site, and there is a pavilion built there to protect it. The Copper Column was made in the first year (1017) of the Tiande reign of the Northern Song Dynasty (960-1127), and inscribed on it is the Treaty between King of Chu Kingdom, Ma Xifan, and the hereditary chieftain, Peng Shichou, to Pledge for Truce. From the last years of the Tang Dynasty (618-907) to the Five Dynasties (907-960), the area of Hunan was a separatist regime ruled by the family of the king of the Chu Kingdom, Ma Yin. Ma commissioned the hereditary chieftain, Peng Jian, as the head of Xizhou (Xi Prefecture), governing several counties including Yongshun, Longshan and Baojing. After Ma Xifan succeeded to the throne after Ma Yin, Xizhou was in the charge of his son, Peng Shichou. In the fourth year (939) of the Tianfu reign of the Later Jin Dynasty, more than ten thousand people of ethnic minorities in Jinzhou, Jiangzhou and Xizhou rebelled against the rule of King of Chu, and the troops headed by Peng Shichou took two prefectures, Chen and Cheng, in the east. Ma Xifan led his army to meet the enemy, but both sides suffered great losses, so they had to cease fire to negotiate for peace, and inscribed their joint covenant on the steel post for it to be erected on the border, specifying that each should govern its own territory, without invasion to each other, the king of Chu should not levy taxes, press people into service, buy local specialties by force, and so on in the prefectures in the administration of the hereditary chieftain.

Steel Column of Xizhou is 4 m in height, and 2,500 kg in weight. The column is a hollow octahedron, but in it originally there were iron coins made in the reign of Family Ma to make it solid. On the column is inscribed the History about the Steel Column of Xizhou, with more than 2,000 elegantly written characters in regular script. It is a precious material data for the study on the relationship of the ancient nationalities of China, and also has a high value as historical data.
