In Lingjiatan, Hanshan County of Anhui Province in China, archaeologists have discovered a primitive tribal site that was inhabited 5,000 years ago. Superb drilling technology and the world's earliest stone drill bits were found at the site. Archaeology professor Zhang Jingguo said there are still many mysteries in the Lingjiatan ruins waiting to be solved.

The Lingjiatan ruins are located in Lingjiatan Village, Tongzha Township of Hanshan County in Chaohu City, Anhui Province, covering about 1.5 million square meters. Archaeologists say the 5,000 year old city was probably a prosperous city with developed construction, animal husbandry and handicrafts. Prior to the discovery of the Lingjiatan ruins, the oldest city in China acknowledged by archaeologists was in Dantu Village in Wulian County at Rizhao City, Shandong Province, which was built more than 4,000 years ago.
