Editing Oracle bone (section)

== After the Shang ==
After the founding of Zhou, the Shang practices of bronze casting, pyromancy, and writing continued. Oracle bones that were found in the 1970s have been dated to the Zhou dynasty, with some dating to the [[Spring and Autumn period]]; very few, however, were inscribed. It is thought that other methods of divination supplanted pyromancy, such as numerological divination using [[Achillea millefolium|milfoil]] (yarrow) in connection with the hexagrams of the ''[[I Ching]]'', leading to the decline of inscribed oracle bones. However, evidence for the continued use of plastromancy exists for the [[Eastern Zhou]], Han, [[Tang dynasty|Tang]],{{sfn|Keightley|1978a|p=4 n.4}} and [[Qing]]<ref>{{harvnb|Keightley|1978a|p=9, n.30}}, citing Hu Xu 1782–1787, ch. 4, p.3b on use in Jiangsu</ref> dynasty periods, and Keightley mentions its use in Taiwan as late as 1972.<ref>{{harvnb|Keightley|1978a|p=9}} cites Zhāng Guangyuan 1972</ref>
