Lajia

Lajia is a significant Bronze Age archaeological site located between the Chinese provinces of Gansu and Qinghai, associated with the Qijia culture. Spanning the late Neolithic and early Bronze Age periods, the site offers insights into the agricultural practices of ancient China, notably millet cultivation and animal husbandry with domesticated sheep and pigs. The presence of proto-porcelain pottery and oracle bones indicates advanced craftsmanship and ritual activities. Remarkably, the world's oldest known noodles, dating back to around 2000 BCE, were discovered here. A catastrophic natural disaster around 1920 BCE buried the site, preserving it for future archaeological study. The combination of domestic, defensive, and agricultural features, along with the evidence of cultural interactions, underscores the site's importance in understanding early Chinese civilization.
