A 4,800-year-old cultural heritage site is being restored in northwest China.
The Dadiwan site is situated in Qin'an county of Gansu province, Xinhua reported.
The heritage site - one of the cradles of Chinese culture - originated in the Neolithic Age. It has some earliest traces of China's agriculture, pottery, painting and writing.
The site also has the country's first palace-like building.
This would be one of the country's ‘largest and most comprehensive restoration’, said Cheng Xiaozhong, head of the Heritage Site Preservation Office.
