1. Palaeolithic sites in Guangdong. More than 60 Palaeolithic sites discovered at Modaoshan Hill and Nanjiang River Basin in the southern Guangdong province show the history of the region's human activity was much longer than people used to believe.

Archeologists collected hundreds of stone artifacts, including stone flakes and hammers, indicating ancient humans lived there as early as 600,000 to 800,000 years ago, compared with the previously thought 130,000 years ago. [Photo/Xinhua]
