On the Days Recorded by the Earthly Branches

It is a common phenomenon that the days were recorded by the Earthly branches in the oracle-bone inscriptions,but some researchers have considered that the Earthly branches can not have been used to record the days in the oraclebone inscriptions or the days can only be recorded lately.In fact,it is the confined materials that lead to these opinions.Some scholars have done many works to arrange the materials which can disclose the days can be recorded by the Earthly branches alone in the oracle-bone,but some materials failed,so this paper will supplement the materials based on the latest research,and ascertain them based on the book rubbing.
