Moreover, these documents were not written by the Shang Dynasty. The discovery of Oracle Bone Inscriptions in Yin Ruins showed a large number of words written and engraved by businessmen to the literati, and separated the history of Shang Dynasty from the legendary era and entered the historical era. Especially in the year of 19 17, Wang Guowei wrote "An Examination of the First Duke and the First King as Seen in the Oracle Inscriptions of Yin Ruins" and "A Continued Examination", which proved "Historical Records of Yin Benji".
It is found that the order of several former officials should be "Bao C" and "Bao D", and the order of "Historical Records" copied by later generations is "Bao D", "Baoyi" and "Bao C". This famous paper irrefutably proves the existence of Shang Dynasty recorded in "Yin Benji". In view of the important position of Yin Shang civilization in the history of world civilization, this is not only a great event in the study of China history, but also a world history.
