Tonggushan Site

　　Era: Shang and Spring and Autumn periods

　　The Tonggushan Site is situated atop Tonggushan Mountain, approximately 500 meters east of Chenjialongtan in Yingpan Village, Qingshan Town, Pu'an County, Qianxinan Prefecture, Guizhou Province. The site covers a total area of 4,000 square meters, with the protected area spanning 41,420 square meters.

　　During two excavations, a total of four house foundations, one kiln site, eleven ash pits, activity surfaces, hearths, and numerous scattered postholes were uncovered. Over 500 relatively intact artifacts were unearthed, including pottery, stone tools, bronze ware, ironware, jade artifacts, and pottery and stone molds used for casting bronze items, along with more than 10,000 fragments of pottery. Notably, aside from some pottery crucibles, the casting molds included those for ge (dagger-axe), jian (sword), yue (battle-axe), arrows, and fishhooks.

　　Excavators believe that the Tonggushan Site was a workshop for casting bronze objects (primarily weapons), with the northern section mainly dedicated to production and the southern section serving as a living area. The site dates back to the Warring States to Western Han period. It is the only officially excavated bronze casting site from the Warring States to Qin and Han periods in Guizhou, holding significant academic, research, and preservation value.
