Historic sites
The Chinese state news agency Xinhua announced in January 2018 the discovery of ruins of an ancient palace that served as the summer retreat for the elite in the Liao Dynasty. The royal family and retinue would relocate each year from mid-April to mid-July to avoid the heat. More than 100 structural components at the site have been found and the foundations of 12 buildings have been recorded. Artifacts found include: glazed tiles, pottery and copper nails. Ge Zhiyong, a researcher with the Inner Mongolia Autonomous Region Institute of Archaeology, date the artifacts to the mid-Liao Dynasty. The dynasty was the first of many dynasties of nomadic origin to merge its nomadic structure and culture with the Chinese style of government.[4]
