Lajia Ruins
Lajia, China
Lajia (pinyin: Lǎjiā) is a Bronze Age archaeological site in the upper reaches of the Yellow River, on the border between the Chinese provinces of Gansu and Qinghai. As at other sites of the Qijia culture (c. 2300–1500 BCE), the people of Lajia had an agricultural economy based primarily on millet cultivation and sheep herding. They also kept pigs for use in ritual activities, including making oracle bones, and experimented with a high temperature-fired pottery described as proto-porcelain. The world's oldest known noodles were discovered at the site in 2005. A natural disaster buried the site and killed many of its inhabitants in around 1920 BCE, but archaeologists continue to debate the exact cause of the catastrophe.
