I. The appearance of metal is a very important event in human history, marking the start of an age. From the patriarchal clan communes of the late Neolithic period to the slave society of the Bronze Age, there was a great change in the relationship between social development and production. As a result, the origin and development of metal-working is one of the important issues in archaeological research (p. 269).
Early in the Shang dynasty, China had already advanced into slave society, and its brilliant bronze culture is an outstanding phenomenon in the history of the ancient world. Shang civilization evolved from Longshan foundations, and there is ample archaeological proof of the close relationship between the two. But from what origins did Shang bronze arise? Before the Shang, was there an aeneolithic period in which copper was used? These questions have not yet been satisfactorily answered. Since 1949 the new discoveries of copper objects and of bronze objects belonging to an early period have contributed important clues to the solution of these problems.
