Chinese civilization, as described in mythology, begins with Pangu, the creator of the universe, and a succession of legendary sage-emperors and culture heroes who taught the ancient Chinese to communicate and to find sustenance, clothing, and shelter. The first prehistoric dynasty is said to be Xia, from about the twenty-first to the sixteenth century B.C. Until scientific excavations were made at early bronze-age sites in 1928, it was difficult to separate myth from reality in regard to the Xia. But since then, and especially in the 1960s and 1970s, archaeologists have uncovered urban sites, bronze implements, and tombs that point to the existence of Xia civilization in the same locations cited in ancient Chinese historical texts. At minimum, the Xia period marked an evolutionary stage between the late neolithic cultures that followed the settlement of nomadic tribes in the fertile valleys of the Yellow Riverand the subsequent first Chinese urban civilization of the Shang dynasty.
Thousands of archaeological finds in the Huang He (Yellow River), Henan Valley --the apparent cradle of Chinese civilization--provide evidence about the Shang dynasty, which endured roughly from 1700 to 1027 B.C. The Shang dynasty (also called the Yin dynasty in its later stages) is believed to have been founded by a rebel leader who overthrew the last Xia ruler. Its civilization was based on agriculture, augmented by hunting and animal husbandry. Two important events of the period were the development of a writing system, as revealed in archaic Chinese inscriptions found on tortoise shells and flat cattle bones (commonly called oracle bones or), and the use of bronze metallurgy. A number of ceremonial bronze vessels with inscriptions date from the Shang period; the workmanship on the bronzes attests to a high level of civilization.
