ZHENGZHOU, CHINA—A 3,000-year-old system of canals has been uncovered at the Yinxu site, the ancient capital of the Shang Dynasty in Henan Province. The 1.5-mile-long system carried water from the Huanhe River through the center of the city, and was nearly 20 feet wide in places. “The water system covers about half the city, running through workshops and the residential areas for commoners, located south of the palaces and temples,” Tang Jigen, head of the Anyang branch of the Chinese Academy of Social Sciences Institute of Archaeology, told Xinhuanet. Archaeologists have also uncovered the city’s system of roads: two arterial roads traveled north-south, while three roads ran east-west.
