Luo Shu Square(AKA Lo Shu or Magic Square) is unique, Chinese history says that Fu Xi uncovered the trigrams after discovering the formula for the Luo Shu on the back of a turtle as it emerged from the Luo River, The odd and even numbers radiate around the centre (number 5) of the Luo Shu square in an odd even pattern; this gives rise to any single line being either +-+ or --- the 4 even numbers are at each corner, and the 4 odd numbers (other than 5) form a cross in the centre of the square. The sums in each of the 3 rows or the 3 columns and in both diagonals are all 15. Number 5 is the centre cell; sometimes referred to as the "Central Palace" the sum of any two other cells which pass directly through 5(Central Palace) is 10.

Whichever direction you add the numbers - horizontal, vertical or diagonal - they always add up to 15. Number 15 is considered a powerful number as it corresponds to the number of days in each of the 24 cycles of Chinese solar year and 24 mountains is also significant in Xuan Kong Feng Shui School. 15 is also the number of days in the cycle of the new moon to the full moon.

The Feng Shui bagua evolved from the Luo Shu Square, in China South is placed at the top of the maps. Number 9 is the number for the South bagua area (on top) and 1 is the number for the North bagua sector (bottom of the square). Odd numbers are Yang energy, and the Even numbers are Yin energy. Numbers in the Luo Shu Square are considered to have specific properties, or express specific energies. For example, number 9 carries a strong Fire Feng Shui element energy, while number 1 is an expression of the water element. In Feng Shui they are called "stars" and they predictable pattern to their movement.

In the flying stars school of Feng Shui (Xuan Kong), the movement of stars is charted each year in order to define the movement of specific energies, both positive and negative. Knowing this pattern, you can create a balanced Feng Shui environment. Each number in the Luo Shu represents a star and each stars movement is tracked using the “Luo Shu Trail”, starting at the central palace and ascending in numerical order i.e. 5 > 6 > 7 > 8 > 9 > 1 > 2 > 3 > 4 once you know this pattern you can float any numbers positive or negative in the luo shu square.

Lets expand it a little , here we see the Luo Shu trail overlaying each number.

Let's take an imaginary knife and cut the trail in half and seperate each side, as you can see the right side is the polar opposite of the right.

Just to be sure lets flip the right side 180 degrees

If you wish to create your own flying star charts, it’s important to get so good at the Luo Shu trail it becomes second nature because if the maths is wrong everything else will be too.

So Practice, Practice, Practice, Practice, Practice, Practice and Practice.

Floating positive numbers is simple but when you have to float negative numbers it’s more difficult let’s do a test run on floating number 3 for positive and negative:

+3 would be 3 > 4 > 5 > 6 > 7 > 8 > 9 > 1 > 2 >

Looks like this;

-3 would be -3 > -2 > -1 > -9 > -8 > -7 > -6 > -5 > -4 >

Looks like this;

And +3 for those interested in the corrosponding directions,

3 > 4 NW > 5 W > 6 NE > 7 S > 8 N > 9 SW > 1 E > 2 SE>

Looks like this;
