Located in the northwest of Liangzhu Archeological Site, Tangshan Mountain is also known as “Nine Ridges” for its nine gaps (passages).

Since 1996, Zhejiang Provincial Institute of Archaeology has conducted several excavation attempts at the Jincun Village section and Mao’ernong gap of Tangshan Mountain. At the Jincun Village section, a batch of jade and semi-finished jade wares were unearthed, and two tombs of the dignitary dating to the later stage of Liangzhu culture cleared.

In another excavation at Jincun Village section from April to July 2002, more than 460 pieces of jade products, a batch of pottery shards and three stone-built ruins relevant with jade making were unearthed in an area of 458 square meters.

It was also discovered that during the building of Tangshan, soil was piled to increase the height continually, and a lot of stones were used to build a revetment at the southern slope.
