The Ye City Ruins, located in Ye Town, Linzhang County, Handan City, Hebei Province, covers a core protected area of 30 square kilometers. It served as the capital of six dynasties: Cao Wei, Later Zhao, Ran Wei, Former Yan, Eastern Wei, and Northern Qi. The Ye City Ruins are rectangular in plan, with an east-west avenue dividing the city into north and south sections. The north section measures approximately 2400 meters east-west and 1700 meters north-south, with seven gates; the south section measures approximately 2800 meters east-west and 3460 meters north-south, with fourteen gates. Ye City, having served as the capital of six dynasties, is the birthplace of ancient Chinese capital city planning and holds significant historical importance in the development of ancient Chinese capital cities, earning it the reputation of being a "model of ancient Chinese capital city architecture." In 1982, the Ye City Ruins were designated as a provincial-level cultural relics protection unit by the Hebei Provincial People's Government. In January 1988, the Yecheng Ruins were designated as a third batch of national key cultural relics protection units by the State Council of the People's Republic of China.
