Calculation method of flying stars in Jiugong

According to Kong Xuan's geomantic theory, if you know when the building was built, you will have the Yuanyun plate of the building. Knowing the sitting direction of the building, you can discharge the fate of the building; If you want to know the good or bad of a building in a certain year.

Calculation method of the period 1900- 1999: subtract the sum of the two digits after that year from 10, and the number is the star that flew into the palace that year. For example, in 1999, 9+9 =181+8 = 910-9 =1(White star enters the palace).

Calculation method after 2000: subtract the twice sum of two digits after that year from 9 (if the sum is a single digit, it can be directly subtracted), and the number is the star that flew into the palace that year. For example, in 2005, 0+5=59-5=4 (four green stars entered the palace).

Arrangement:

Jiugong is arranged in Roman characters, and the trajectory of flying stars starts from Zhonggong and then moves in the order of Tam font size. Therefore, the flying star trajectory is also called the body trajectory (body gait). Shun Fei: Numbers are arranged from small to large. Reverse flight: the numbers are arranged from big to small.

According to the order of flight before and after, according to Luo Shu, from one stem to one, one ridge, one Kun, one earthquake and one Xun are arranged. The Sanyuanjiuyun started from the Yellow Emperor, and sixty calendars were interpreted. Up to today, there are 78 flowers. One yuan is divided into three shipments, and one shipment is twenty years.
