The site is located at the southern foot of Zhongjia Mountain near Tianma Mountain. In 1960, when local farmers were digging mud, they found black-skinned pottery dou (stem bowl), clay grey pottery and other incomplete vessels, the pottery pieces with back-shaped pattern, mesh pattern and other impressed patterns, and incomplete stone vessels.

They are in the category of Tinglin under Wu-Yue culture in the Western Zhou Dynasty (1046~771 BC), about 2,500 years ago. In 1990, the professionals of the Songjiang County Museum also collected stone axes, broken pieces of grey pottery clarifiers, incomplete black-skinned grey pottery jars and hard pottery pieces with impressed patterns on the site. Now the site locally becomes a large water pond.
