These 60 trunk-branch cycles are circulated once every 60 years, commonly known as "60 flowers". In life, we call the elderly who are over 60 years old the year of 60 or the year of 60 years old. People have paid attention to their 60th birthday. In fact, it is also because 60 years old belongs to a year when a person has finished a year of 60 years old, which is an extraordinary year, so 60th birthday is generally taken seriously. In history, events such as the Sino-Japanese War, the Sino-Japanese Treaty, the Reform Movement of 1898, the Revolution of 1911, etc. are often recorded by the 60-year calendar.
The method of matching sixty Jiazi in turn is as follows: In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Ren and Gui were called "Ten Days Dry", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai were called.
The heavenly stems and earthly branches are all combined in turn from the beginning, which is a match between Yang and Yang, and a match between Yin and Yin, but not between Yin and Yang. The specific method is that ten heavenly stems are matched to the last one in turn from the first one, and the ground branches are matched to the last one in turn from the first one.
The first match is called Jiazi, and the second is called Yechou, and so on: Bingyin, Dingmao, Wuchen, Jisi, Gengwu, Xinwei, Renshen and Guiyou. Since there are ten heavenly stems and twelve earthly branches, there are two earthly branches left after the last "decyl" of heavenly stems is matched.
Then, the remaining two branches continue to circulate in turn, until heavenly stems and earthly branches is completely reincarnated. The * * * meter means that the heavenly stems are reincarnated for six times, and the earthly branches are reincarnated for five times, which is exactly 60 times to form 60 years. This is a complete Jiazi, which is the so-called 60 Jiazi.
What is Na Yin? Na Yin is a widely used method to retrieve numbers in ancient China's divination. Its corresponding mathematical theory has been clearly defined by Na Yin in Sixty Jiazi, and its basic meaning is expounded by "Five Elements". The "sound" of "Na Yin" is the pentatonic determined by the people of ancient China according to different scales.
Na Yin was originally a musical note in ancient Chinese music. Ten heavenly stems and twelve earthly branches were matched in sequence, from Jiazi to Guihai, and sixty combinations of * * * were sixty Jiazi. Then, every two groups in the sixty jiazi are matched with a five-element phonetic alphabet to form the theory of phonetic alphabet, which is called phonetic alphabet for short.
