The Neolithic Shuanghuaishu site in Gongyi, Henan


 The Zhengzhou Municipal Institute of Cultural Relics and Archaeology excavated at the Shuanghuaishu site in Gongyi, Henan between 2013 and 2020. The excavated features include three encircling trenches, a core residential area, large rammed earth building complexes, rammed earth sacrificial altars, tombs, ash pits, and pottery kilns. Unearthed artifacts include pottery, stone tools, and objects made of animal teeth. The Shuanghuaishu site has been so far the largest middle to late Yangshao residential settlement in the Yellow River valley. Shuanghuaishu and the multiple sites in the neighboring region altogether led to the formation of an impressive site complex on a regional scale.
