Three yuan, nine innings, nine palaces and flying stars.

"Three Yuan Nine Games" is China's method to divide the big time. The ancients divided 20 years into one fortune, and three 20 years were three fortunes, forming one yuan. Theoretically, it is the core of Jiugong Xing Fei Feng Shui School, which is divided into four types, namely Jiugong Xing Fei, Jiugong Xing Fei, Jiugong Xing Fei and Jiugong Xing Fei.

The ternary games are Shangyuan, Zhongyuan and Xia Yuan, and each yuan has three games, which are collectively called "Sanyuan Nine Games".

Among the nine planets in the solar system, Saturn and Jupiter meet once every 20 years and are in a straight line; Saturn, Jupiter and Mercury will meet once every 60 years. Every 180 years, the nine planets will be on the same side of the sun, distributed in a small fan shape, forming a "nine-star connection".

At the same time, the operation law of Beidou plus the left satellite and the right satellite coincides with the natural phenomena and the good or bad luck of people on the earth, and one plays a leading role every 20 years. The ancients had a thorough understanding of this opportunity, and regarded 180 as a positive element, and each positive element contained three elements, namely Shangyuan, Zhongyuan and Xia Yuan. Sixty years per yuan, divided into three shipments.

Every 20 years, that is, Shangyuan is the 1st, 2nd and 3rd Universiade, Zhongyuan is the 4th, 5th and 6th Universiade, and Xia Yuan is the 7th, 8th and 9th Universiade, thus forming a complete ternary and 9th Universiade system.

This celestial body goes round and round and never changes. On this basis, by organically combining the "Three Yuan Nine innings" with the Nine Palaces of Luoshu, the Big Dipper and the Nine Qi with the left and right auxiliary stars as the nine planets, a set of geomantic theory with the unity of "time" and "space" has been established and developed, which can accurately calculate the luck of Yangzhai, the good or bad luck of people and even the national luck.

There is a saying in Feng Shui that "there are nine planets in the sky and nine palaces underground", and the nine planets are one white, two black, three green, four green, six white, seven red and eight white nine purple in Huang Wu.

Each star is in charge for 20 years, which is good luck; Every group of three stars, a total of 60 years (a flower), that is, one yuan. The ternary combination of the upper, middle and lower reaches is 180 years, which is a positive element.

Five elements of nine planets:

A white star, a divination, belongs to water; Two black stars, Kun hexagrams, belong to the soil; Three stars, a hexagram, belong to wood; Four green stars are hexagrams and belong to wood; Five yellow stars, in the middle palace, have no corresponding divination; Six white stars, dry hexagrams, belong to gold; Seven red stars are easy hexagrams and belong to gold; Eight white stars are hexagrams, belonging to the earth; Nine purple Star, as a divination, belongs to fire.

There are five lucky stars and four unlucky stars in the flying stars, which reflects the changing law of the wind and water turns.
