Digital divination can be found in Bamboo Slips of Tsinghua and Divination Law.

China Social Sciences Journal reported "A New Case of Digital Divination-Hua Qing Jian" and "Sword Method or Providing Evidence" in No.465, June 265438+June 2, 2003. Li Xueqin introduced that the content of "Sword Method" was digital divination, which was very puzzling and raised new questions for researchers. The length of this piece of paper is 45cm, and there are ***63 pieces with numbers. The organizer temporarily divided it into 36 sections, which are closely related to each other. There are examples of hexagrams in each section, and they are all digital hexagrams. This paper introduces the theory and method of divination in detail, and lists many examples of digital divination. The structure of these digital hexagrams is basically consistent with the actual digital hexagrams recorded in Chu bamboo slips such as Tianxing Guanjian, Baoshan Bamboo Slips and Geling Bamboo Slips. Therefore, the appearance of this paper may open a new situation for the study of digital hexagrams, and will also bring new opportunities for the progress of the study of Yi. In addition, this paper also found the names of hexagrams in Gui Zang, and the relationship between divination on Chu bamboo slips and Gui Zang is worth studying. Prying Method was compiled into the fourth series of Chu Bamboo Books of Warring States Period in Tsinghua University, and was published at the end of 20 13.
