The Origins Of Chinese Civilization

What is now China was inhabited by Homo erectus more than a million years ago. Recent study shows that the stone tools found at Xiaochangliang site are magnetostratigraphically dated 1.36 million years ago. The archaeological site of Xihoudu (西侯渡) in Shanxi Province is the earliest recorded use of fire by Homo erectus, which is dated 1.27 million years ago. The excavations at Yuanmou and later Lantian 蓝田show early habitation. Perhaps the most famous specimen of Homo erectus found in China is the so-called Peking Man discovered in 1923-27.

Three pottery pieces were unearthed at Liyuzui Cave in Liuzhou, Guangxi Province dated 16,500 and 19,000 BCE.
