Mr. Gu Jiegang believes that the divinatory words in the Book of Changes recorded the characters and deeds from the Shang Dynasty to the early Western Zhou Dynasty, such as Gao Zongfang and Emperor Yi Guimei, and inferred that the writing age of the divinatory words in the Book of Changes should be in the early Western Zhou Dynasty. These characters and deeds recorded in the divinatory words of the Book of Changes have been confirmed by the literature unearthed in recent years
The argument in the argument does not determine the lower limit of the age of the work
Mr. Gu's presumption is reliable.
