Yinxu royal grave ruins on honor list

Last year, archaeologists found a makeshift human camp, dating back 11,000 to 15,000 years, at the Zhaojiaxuyao site in Zibo, Shandong province. There were remains of fireplaces, animal bones and pottery items.

"Discoveries made at the site filled the gaps in our understanding of the transition period between the Paleolithic and Neolithic ages. … The site is helping us study the origins of agriculture and pottery in Northern China," Chen said.
