In a remote region of Inner Mongolia, archaeologists have discovered a 4,500-year-old Hongshan Culture jade-working hub that challenges existing timelines for early Chinese social complexity. The excavation uncovered several residential clusters and a centralized ritual plaza containing "spirit-tablets"—flat jade stones carved with intricate avian and zoomorphic motifs that some scholars believe represent a proto-writing system.
The site also features the world's earliest known specialized micro-drill workshop, where hundreds of tiny flint and bone tools used for boring holes in jade were found in situ. This discovery underscores the high degree of economic specialization in the Hongshan civilization and its role in developing the ritual jade traditions that would later define the Shang Dynasty.
