The Ganzhi chronology, a unique Chinese chronological calendar, is like a symphony of time, which uses the ten heavenly stems - A, B, C, D, E, G, XIN, NON, and the twelve earthly branches - Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai, together to construct the cycle of the 60 Jiazi.
There is a legend about its origin, but there are also voices that believe it began in the Han Dynasty. Archaeological circles have found inscriptions on the Ganzhi records in the oracle bone inscriptions of the Shang Dynasty, which provides strong evidence for the beginning time of the Ganzhi chronology. Regardless of its exact origin, the use of the stem branch in the field of ** science gives the time cycle a five-element symbol, as if inlaid with colorful gemstones for the passage of time.
Ancient astronomers seem to have echoed the trajectory of the stars with the rhythm of heaven and earth from the beginning of Fu Xi's observation of the heavenly phenomena. The orbital cycle of Saturn and Jupiter coincides with the 60-year cycle. Saturn's orbital period is about 2953 years, while Jupiter's orbital period is 1186 years. The least common multiple of the orbital cycles of these two planets coincides with the annual cycle of 60 Jiazi.
The Zodiac, a masterpiece of ancient astronomy, divides the starry sky into dreamlike signs. It takes about 30 years for Saturn to orbit one of its zodiac houses, and the length of each house is exactly 25 years; Jupiter, on the other hand, takes about 12 years to orbit one of its 12 houses, and each house takes exactly one year. These twelve earthly branches, like messengers of time, silently guard every palace.
And the conjunction period between Jupiter and Saturn is exactly twenty years. When the two planets are at an angle of 0 degrees or 180 degrees, they seem to be engaged in a silent dance, forming a 10-day dry cycle. The trajectory chart clearly shows the wonderful phenomenon of Saturn and Jupiter in the same house and in the opposite house of the triplet.
In this 60-year diagram of the sub-cycle, the pentagon shows the naming of the Earth's branch in which Jupiter orbits for five weeks, with a sub as the starting point and a cycle of 12 years. The hexagon shows the conjunction cycle of Saturn and Jupiter, where they meet in the same house every 20 years. This law seems to be the code of the universe, silently written among the boundless stars.
The energy of the stems seems to be a change caused by the difference in the number of angles between the planets. When Saturn and Jupiter are at an angle of 0 or 180 degrees, their energy shines like the gold of hept. This energy changes with the increase of the included angle, forming the energy of nondecane methyl and propylene and pentehexine.
The earthly branch is the corresponding 12 zodiac houses in the sky, just as the moon rotates through the 12 months of the year. The celestial stem is the angle formed by the movement of the planets, and the increase of this angle forms the energy of the five elements. Although we have not yet invented an instrument that can measure this aura, its existence must act on the solar system and between all things. The ancients came to the mystery of this universe through observation and summarization, and through the verification of time.
In order to further uncover the subtle connection between planetary cycles and human beings, we will continue to write a concluding essay on history and time cycles. Let's delve into the mysteries of this universe and feel the beauty of the interweaving of time and space.
