ZHENGZHOU, Jan. 26 (Xinhua) -- Chinese archaeologists have found the ruins of an ancient urban water system from the Shang Dynasty (1,600 BC-1,046 BC) in central China's Henan Province. It is believed to be the earliest urban water system in the dynasty.
The water system is part of the Yanshi ruins, an ancient city discovered by archaeologists in 1983. The city, spreading over about 2 square km, was built in three layers -- the big city, the small city and the city palace.
"The internal water system was mainly used for drainage, and the external water system included a moat and two river courses," said Chen Guoliang, an archaeologist with Chinese Academy of Social Sciences and leader of the archaeological team of Yanshi ruins.
