In ancient China, the sky was dominant and the earth was subordinate. The connection between the sky and the stem was called the heavenly stem, and the connection between the ground and the branch was called the earthly branch. Together, it was called heavenly stems and earthly branches, which was called the trunk branch for short.

There are ten heavenly stems, namely, A, B, C, D, E, Ji, G, Xin, Ren and Gui, and twelve earthly branches, namely, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. The ancients put them together in the order of Jia Zi, Yi Ugly and Bing Yin (that is, the sky turns six times and the earth turns five times, which is just a cycle), and sixty pairs from Jia Zi to Gui Hai were called Jia Zi.

The ancients in our country used these sixty pairs of branches to represent the serial numbers of year, month, day and time, which went on and on, and this is the chronology of branches.
