These ruins cover an area of twenty-five
square kilometers in downtown Zhengzhou.
In 1955, a city wall of seven kilometers
was discovered on the site.
Archaeologists have found ruins of house
foundations, cellars, water wells,
ditches, and graves. Ornaments and tools
made of bronze, stone, bone, shell, and
jade were found on the site, as well as
pottery and primitive china. Outside the
walls, the ruins of various workshops
were discovered, among which were
foundries for smelting bronze and
workshops for making pottery and for
polishing bone articles.
These archaeological finds in Zhengzhou
provide valuable materials for the study
of Shang Dynasty society, particularly
with regard to the formation and
development of ancient cities in China.
