Branches used in foundation of ancient city uncovered

Shangqiu was the first capital of the Shang Dynasty (c.16th century-11th century BC) and later served as the capital of some states. It is known as the site of "cities above cities", as new cities continued to cover the relics of the old throughout its long history.

Archaeologists have also uncovered wells and ash pits below the branches, as well as daily utensils, such as pottery jars that date back to the Eastern Zhou Dynasty (770-256 BC).
