There are thirteen chronicles of bamboo books, which record the history of Xia, Shang, Western Zhou, Spring and Autumn and Warring States, and are compiled annually. After Zhou Pingwang moved eastward, he used the Jin calendar, and after three points of Jin, he used the Wei calendar until the twentieth year of the present king. Xun Xu and others corrected the mistakes in the historical records according to the Annals of Bamboo Slips and the Historical Book of Zhao in the Warring States Period, and thought that the "present king" was the tomb. At that time, He Gui thought that "the chronicle originated from the Yellow Emperor", but this opinion was not fully adopted. It is possible that only the incomplete bamboo slips that record historical events since the Yellow Emperor are used as supplements to the book.
