What days are there?

"Ganzhi" is the abbreviation of "heavenly stems and earthly branches", which is an ancient calendar. The ancients said, "Heaven is dry, wood is dry, and strength is yang. Branches, branches, weak and cloudy. It can be seen that the meaning of heavenly stems and earthly branches comes from trees.

1, ten days dry: A, B, C, D, E, G, Xin, Ren, Gui.

2. Twelve branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You and Yi Hai. Put it together.

For example, ten heavenly stems and twelve earthly branches are matched in turn in a fixed order, and they are repeated and combined head to tail to form sixty words, which we collectively call "Sixty Jiazi".

At the same time, the twelve earthly branches also correspond to the corresponding zodiac signs, namely, rat, ugly cow, silver tiger, hairy rabbit, dragon, snake, afternoon horse, sheep, monkey, chicken, dog and pig.

Heavenly stems and earthly branches is divided into yin and yang in sequence, with odd numbers as yang and even numbers as yin. Shi Zhixin, a master of Feng Shui, said that it is very important for the five elements to generate grams.
