The site of the Shang dynasty capital from 1500-1200 BC, in Honan province, China on the Yellow River. Following villages of the Yang Shao and Lung Shan cultures, four phases of Shang occupation have been traced. Cemeteries of pit graves have been found and a rectangular wall enclosed an area divided into different quarters. Outside this city, in addition to remains of large public buildings, a complex of small settlements has been discovered. Since 1950 archaeological finds have shown that there were Neolithic settlements in the area. The site remained occupied after the Shang dynasty moved its capital again; Chou (post-1050 BC) tombs have also been discovered. It is thought that in the Western Chou period (1111-771 BC) it became the fief of a family named Kuan. In 605 AD it was first called Cheng-chu.
