Xiangzi Wushan

If you understand positively and don't understand, it means you don't understand positively! First of all, the compass circles the sky 360 degrees. One divination and three mountains, each divination is 45, each mountain 15 degrees. The theory is that every mountain is a positive line within 9 degrees, which is what we call positive. Both sides are in the same direction within 3 degrees. 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.
