Daxi Culture Site

　　In 1979, a batch of polished stone tools such as stone knives and stone axes were discovered near the Nanhu Submerged Pipe in the Xinhul Fishery of Hekou Township, Nan County. After examination, it was confirmed that this site is a late Neolithic Daxi Culture site. Later, the People's Government of Nan County designated the area as the "Xinhu Site" and listed it as a county-level cultural relics protection unit. In 1986, cultural relics archaeologists discovered another Shang and Zhou culture site beneath the silt layer in Beihekou Township.
