Rhizoma Polygoni Multiflori: A, B, C, D, E, F, G, F, N, D..
Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai.
the twelve earthly branches correspond to the Chinese zodiac: mouse, ox, tiger, rabbit, snake, horse, sheep, monkey, chicken, dog and pig.
The arrangement of ten-day stems and twelve-day branches starts from Jiazi and ends in Guihai, which is exactly 6 groups, so 6 years is a Jiazi, and the same arrangement is also used to record the moon and the sun. The combination arranged on the first day of the year/month can be used to address the year/month. For example, the first day of 1984 is Jiazi Day, and the child corresponds to a mouse, so 1984 is the year of the mouse. The year of the title is not quite right. It is necessary to add heavenly stems to the year, month and day, and remember them together as two words. For example, 1986 is the year of Bing Yin, and the year number of the emperor in ancient China can be added to continue the record without chaos.
As for Yin Shi's statement, the ancients divided a day into 12 hours, and one hour is equivalent to two hours now. Take twelve places to record, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.
the hours are from 23: to 1: , and each hour is two hours, and so on, and it is from 3: to 5: in Yinshi.
The year/month/day/hour of a person's birth adds up to birthdates.
