On the 7th, the reporter learned from the archaeological site of the new school site of Jingzhou Middle School that archeologists unearthed dozens of bamboo slips from the tomb of a warring country earthen pit last weekend, providing important textual information for studying the history and customs of the Warring States period.
According to the archaeologist Tian Yong, the grave of unearthed bamboo slips was a medium-sized earth pit tomb of the Warring States Period. When Bamboo Jian was unearthed, it was impossible to determine the amount of bamboo slips because many of them were broken and they were about dozens or so. Some of the bamboo slips are still vaguely recognizable, but subject to the effects of oxidation, the color of bamboo slips after unearthing becomes black. “Since the bamboo slips are not easy to preserve, the probability of unearthing is extremely low. The unearthing of these bamboo slips provided the most direct textual information for the history at that time.†Next, the archaeological team will hand over the bamboo slips to the Jingzhou Cultural Security Center. Only after the restoration is completed can we know Bamboo slips on the specific content.
In addition to bamboo slips, the tombs also had excavated weapons such as Ge and bows, and the tombs were relatively well-preserved. According to the scale of the tombs and burial articles, the tomb owner had a certain social status.
In addition, in order to cooperate with the construction project of the new campus of Jingzhou Middle School, the archaeological site has already excavated 236 ancient tombs and a total of more than 1,400 pieces of cultural relics have been unearthed.
