Damn it, eighth place, what do you mean by "first"?

Represents the number of digits, and the number of digits represents 8.

According to legend, "heavenly stems and earthly branches" was created by a great troublemaker during the Yellow Emperor's reign. Archaeology believes that shamanism (shamanism here is not shamanism in Qing Dynasty) appeared in the early stage of Chinese civilization, and then with the development of history, nobles who were originally engaged in sacrificial activities United and gradually evolved into Yin and Yang Taoism, which is considered magical because there are many predictable aspects of divination in its application. This is still a mystery to modern people! In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Ren and Gui were called "ten heavenly stems", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai were called "twelve earthly branches". The two cooperate with each other in a fixed order, forming the discipline of cadres and branches. Judging from the Oracle Bone Inscriptions unearthed in Yin Ruins, in ancient China, the trunk and branch were mainly used to record the days, as well as the months, years and hours. After the Tang dynasty, the chronology of the main branches was mainly used for fortune telling or divination.
