Principle of directional diffraction twenty-four scenes method

Twenty-four mountains are equivalent to twenty-eight nights. Geomantic omen divides these directions into twenty quadrants, each of which accounts for 15 degrees. Because 24 directions are used to determine the direction of the mountain, it is also called 24 directions. The orientation of the Twenty-four Mountains is represented by twelve branches plus eight branches, with four dimensions: twelve branches are Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai, and eight branches are A, B, C, D, G, Xin, Ren and Gui, and four dimensions are Gan, Kun and Gui.
