For example, in Zi Shan, the middle 360 degree is also called 0 degree, and 4.5 degrees to the left and 4.5 degrees to the right are all positive. And if you pass, you will go in the same direction. If you are over there, you will be said to be in that direction. If both directions are exceeded, it is an empty line and a dead line.
Now the actual operation should be that 8 degrees in the middle of the mountain is positive (4 degrees around the middle of the mountain includes 4 degrees). The left and right are greater than 4 degrees and less than or equal to 6.5 degrees are all directions. More than 6.5 degrees is an empty line. So it is between 184 degrees and 186.5 degrees when measured in Wushan.
What is "Feng Shui"? There are countless people who have defined Feng Shui since ancient times. Guo Pu, who first defined geomantic omen in history, said in his famous book "The Book of Burial": "When the burials are angry, the gas will be dispersed by the wind, and the boundary water will stop. The ancients gathered to stop it, so it was called Feng Shui. The method of geomantic omen is water first and wind second.
It can be seen that the technique of geomantic omen, that is, the technique of knowing each other, is the core of people's choice of living or burying environment and dealing with the law of cosmic change, so as to achieve the goal of seeking good fortune and avoiding evil. Feng Shui can be divided into Yang Zhai and Yin Zhai.
