The Guangyang City ruins site, located in Hebei Province, Langfang City, is a civilization code sleeping for two thousand years on the Yan Zhao land. The mottled rammed earth wall base and intermittent city wall outlines delineate the administrative layout of the Han Dynasty county town, and the remaining pottery shards, weapons, and copper fragments are scattered like stars, telling of past prosperity and vicissitudes. The most shocking part of the site is the well-preserved rammed earth wall base, with its regular stone arrangement and ingenious drainage system, showcasing the high level of Han Dynasty architectural craftsmanship.
