It also appeared as ceremonial and symbolic jade weapon at around the same time, two being dated from about 2500 BC, are found at the Lingjiatan site in Anhui. The first bronze ge appeared at the early Bronze Age Erlitou site, where two were being found among the over 200 bronze artifacts (as of 2002) at the site,three jade ge were also discovered from the same site. Total of 72 bronze ge in Tomb 1004 at Houjiazhuang, Anyang, 39 jade ge in tomb of Fu Hao and over 50 jade ge at Jinsha site were found alone. It was the basic weapon of Shang (c.1600–1050 BC) and Zhou (c.1050 –256 BC) infantry, although it was sometimes used by the “striker” of charioteer crews. It consisted of a long wooden shaft with a bronze knife blade attached at a right angle to the end. The weapon could be swung down or inward in order to hook or slash, respectively, at an enemy. By the early Han Dynasty (202 BC–220 AD), military use of the bronze ge had become limited (mostly ceremonial); they were slowly phased out during the Han Dynasty by iron spears and iron ji halberds.
