In 2009, a small-scale trial excavation was conducted to Xueshan Site at Chengjiang County, Yunnan Province. The trial excavation recovered a semi-subterranean house foundation (F1) and a stilt house foundation (F2). The potteries and bronze arrowheads unearthed from F1 were similar to the artifacts of Shizhaishan Culture and therefore this house foundation would have belonged to Shizhaishan Culture, and was used as refuse pit after it was abandoned in the Six Dynasties Period. Only a small part of F2 was recovered in this excavation and its date is still waiting for further fieldwork.
