What do the numbers in Feng Shui mean?

The numbers 1 and 6 in the five elements are water; 2, 7 is fire; 3, 8 is wood; 4, 9 is gold; 5,0 is dirt.

In the Eight Diagrams and Nine Palaces, 1 is Kanshui; 2 is Kuntu; 3 is shock wood; 4 is rafters; 5 is the palace soil; 6 is dry gold; 7 is the exchange of gold; 8 is root soil; 9 stay away from the fire.

The odd number is Yang, and the even number is Yin.
