East Asian archaeology studies the ancient cultures and societies of countries like China, Japan, Korea, and Mongolia. Researchers explore artifacts, structures, and landscapes to understand the region's history, including the development of agriculture, trade, and urbanization. Significant discoveries include the Terracotta Army in China and ancient burial mounds in Japan. This field also examines the influence of Buddhism and Confucianism on East Asian societies. Archaeologists use techniques like radiocarbon dating and remote sensing to uncover sites and analyze findings. The goal is to piece together the rich tapestry of East Asia's past and its impact on contemporary cultures.
