Archaeologists focused on excavating the No 1 tomb, which has been confirmed to be a square tomb with a tomb passage. In the center of the tomb pit, there are nine burial chambers arranged in a cross shape with one central chamber and eight side chambers surrounding it.

Bronze ritual artifacts, daily utensils, wooden figurines and musical instruments were unearthed from the side chambers. Ink inscriptions were also found on the cover boards of the burial chambers, according to Gong Xicheng, a researcher at the Anhui Provincial Institute of Cultural Relics and Archaeology.
