3. The Majiayao Cultural settlement from Siwa Site in Lintao county, Gansu province
The site is situated west of Jiulong Mountain, with remains mainly distributed on the gently sloping land in front of the mountain. Discoveries include remnants of the Majiayao culture (an ancient Chinese culture dating back more than 5,000 years), covering an area of approximately 2 million square meters. The Majiayao culture at the Siwa site showcases the developmental level and civilization of the early societies on the Loess Plateau in western China 5,000 years ago. It fills a crucial gap in the research of the origins of Chinese civilization in the upper reaches of the Yellow River during a key period, greatly enriching the understanding of the origins and early development of Chinese civilization in terms of content and patterns.
