Introduction to the Xia and Shang Dynasties in the Central Plains of Dingding: The mystery of the first dynasty is hidden deep in Erlitou among the vast nine states and the vast traces of Yu. With splendid weapons and powerful cities, the city of Shang King laid the foundation of the Bronze Age. The Yin Ruins in Anyang is a holy land for archeology, but the sight of animals being sacrificed and oracle bones is astonishing. The mausoleums and palaces are made of ferocious bronze. Where is the chaste man and where does the king return? The fierce fire of the middle earth shines across the country thousands of miles away.
