What auxiliary divination methods did the Zhou Dynasty use?

According to ancient documents, Zhou people, like businessmen, used tortoise shells to predict good or bad luck very early. As early as when Gu's father moved, he used tortoise shells for divination seriously. The omen is very auspicious, and Zhou people began to settle here. This is a historical event reproduced in the article "The Book of Songs, Elegant Noodles" quoted in the last part of "The Discovery of Joo Won? Ancestral Temple and Yandian Site".

After the demise of the Shang Dynasty in the Western Zhou Dynasty, the custom of recording the whole process of divination with Oracle bone inscriptions was also inherited and used by the Western Zhou people. However, it may be influenced by the development of gossip, which is said to have been created by Wang Wen, the ancestor of Zhou people. The popularity of gossip divination led to the transfer of Zhou people's interest in Oracle Bone Inscriptions's divination, so the application of Oracle Bone Inscriptions in the Western Zhou Dynasty lost the glory of the Yin people. "Zuo Zhuan" contains fifteen years of promise to the public, "the tortoise elephant is also counted."

"Divination" means that divination is a method to judge good or bad according to the change of numbers. Zuopian of Shiben said: "Wu Xian made divination", and "Wu Xian" was a minister of Taiwu, the king of Shang Dynasty, and divination had appeared in Shang Dynasty, which was confirmed by archaeological discoveries in Yin Dynasty. During the reign of King Wu, in order to continue to develop eastward, the capital moved from Fengjing, built by Wen Wangjian, to Gaodi. In order to make this important action get God's blessing, Zhou Wuwang did some divination with tortoise shells as usual.
