Three Yuans and Nine Lucks is the Chinese way of dividing time. The ancients divided 20 years into one luck. Three 20 years are the three lucks, forming one yuan. The three Yuan Yuans are the Upper Yuan, the Middle Yuan and the Lower Yuan. Each Yuan has three movements, collectively called the "Three Yuans and Nine Yuns".
Shangyuan refers to the first, second, and third movements; Zhongyuan refers to the fourth, fifth, and sixth movements; and Xianyuan refers to the seventh, eighth, and ninth movements. Each Yuan Yun is sixty years old, and the total length of the Three Yuans is 180 years. It has been recorded in the almanac since ancient times and used in conjunction with the Ganzhi calendar, mostly in Feng Shui.
Among the nine planets in the solar system, Saturn and Jupiter will meet once every 20 years and are in the same straight line; every 60 years, Saturn, Jupiter, and Mercury will meet once; every 60 years, Saturn, Jupiter, and Mercury will meet once. In 180 years, the nine planets will be on the same side of the sun, distributed in a small fan, forming a "nine-star continuum."
Because this law of movement of celestial bodies never changes, astronomers delineate the time system of "Three Yuans and Nine Movements" based on this law, with 180 years as one positive year, and each positive year is divided into The upper, middle and lower three yuan, each yuan has 60 years, and each yuan is divided into three fortunes, namely one to nine.
At the same time, there is a certain coincidence between the movement patterns of the Big Dipper, the Left Auxiliary Star and the Right Star, and the natural phenomena and human affairs on the earth. One of the stars rises every 20 years. leading role.
“The four directions above and below are the universe, and the past and present are the universe. The universe and the universe refer to space and time respectively.” Ancient ancestors looked up at astronomy and geography. After a long period of observation, they discovered that there is a certain internal regular connection between the movement patterns of the major planets in the solar system and the movements and changes of natural and human phenomena on the earth, especially Jupiter. The movement of planets and Saturn has a great influence on the earth.
The laws of movement of celestial bodies repeat in cycles and never change. Based on this, through the organic combination of the "Three Yuans and Nine Lucks" with the Nine Palaces of Luoshu, the Big Dipper plus the left auxiliary star and the right auxiliary star as the nine stars, and the nine qi, a set of "time" and "space" was established and developed. Unified Kanyu theory. Jupiter takes about twelve years to orbit the sun, and Saturn takes about thirty years to orbit the sun.
Jupiter and Saturn meet once every twenty years. The conjunction of the two planets will exert various influences on us in ways that we are not aware of. Therefore, metaphysicians divide a Yuan Yun into twenty years.
