Which cultural relics unearthed in Jingyang belong to which dynasty?

199 1 On August 5, 2008, five ancient tombs dating from 3 100 were excavated in Gaojiabao Village, Xinglong Township, Jingyang County, Shaanxi Province, and 39 well-preserved bronzes and other important cultural relics were unearthed. According to reports, it is very rare for so many complete bronze ritual vessels to be unearthed from tombs in the late Shang Dynasty without being disturbed. This is an important discovery of Shang and Zhou archaeology in China. It is inferred that these tombs may be the cultural remains of small countries in the late Shang Dynasty, or some remains of activities in this area in the early Zhou Dynasty (before the establishment of the Western Zhou Dynasty).
