According to the Archaeological Institute of Shaanxi Province, archaeologists found ancient tombs, ash pits and a long ditch in the style and scale common to the Xia dynasty when they did excavation work to Lao Niu Po ruins in Xi'an recently.
The cultural remains found in Xi'an are farther west than any other Xia dynasty ruins found so far, which indicates that the Xia dynasty's orbit reached to the middle of Central Shaanxi Plain region in old days.
Last December, archaeologists from the Shaanxi Archaeological Institute unearthed 129 ash pits, four pottery kilns, 25 tombs, eight houses and more than 600 pieces of pottery, stones and jade during the archaeological excavation to Lao Niu Po ruins.
Among the ancient remains they had found, there are four Xia-era tombs with two to eight burial objects in each. In a more than 70-meter-long south-to-north ditch, pottery and remains belonging to the late culture of Er Li Tou, a city identified as a capital of the Xia dynasty, were found.
In addition, archaeologists did not find any objects later than the Xia dynasty, which indicates that the ditch could not have been constructed in period of time later than the Xia dynasty.
