Chen Dahai, archaeological project leader of the Xijie site and deputy research librarian of the Nanjing Archaeological Research Institute, said that in the active archaeological excavation, a terrace in the northern part of the site parcel was the first to be presented, and the cultural layers and relics at the edge of the terrace were the richest, and the eastern edge of the ring-shaped trench was better preserved, with at least four ring trenches from different periods of the Shang and Zhou Dynasties found. "In ancient defense facilities, trenches appeared earlier than cities. A defense system with a city wall paired with trenches is an important symbol of ancient cities." Chen Dahai revealed that the remains of a section of the wall foundation in the northeast of the terrace are clearly visible, and about 10 meters east of the wall foundation, a trench with the same direction as the wall foundation was also found to be localized, and the combination of this section of the wall and the trench has become another tangible evidence that a city was built here.

As the excavation continues, more evidence points to the conclusion that Nanjing's earliest city can be traced back to the Shang and Zhou dynasties: there are obviously collapsed rammed-earth walls in the ring trench; the wells on the periphery of the ring trench were built in the Late Shang Dynasty; the pottery with triangular rows of lines, trapezoidal patterns and other decorations unearthed at the site has obvious characteristics of the Shang Dynasty; pig bones, charcoal and other pieces of unearthed relics were calculated by carbon-based 14 dating, which resulted in the timeframe of the Late Shang and Early Zhou periods. The excavated relics of the Shang and Zhou Dynasties at the Xijie site are relatively abundant, including ceramic ceramics, earthenware vessels, ceramic tripods, ceramic beans, ceramic gui, ceramic goblet-shaped cups, ceramic jia, primitive ceramic jars, primitive ceramic beans, jade jade, copper, and so on.
