In July 1999, the Office of cultural relics and archaeology excavated 37 square meters of an early site inside the Ruzhou city. Large amount of porcelain sherds were yielded. Four sherds can be securely identified as the products of Imperial Ru kiln. In addition, a rammed earth foundation and drainage facility of early northern Song were recovered. This test esxcavation enables a preliminary understanding on the characteristics and cultural development of the site.
