In Feng Shui, the meridian direction of Zishan and the Wei direction of Choushan refer to the sitting direction of the building. To be precise, it refers to the orientation line of the longitudinal central axis of the building. The side behind the house is the sitting direction. , the front is Xiang.
Zishan is within the range of 7.5 degrees around 360 degrees, that is, between 352.5 degrees and 7.5 degrees; Choushan is 22.5 degrees to 37.5 degrees.
Zi Shan Wuxiang means that the back of the house is Zi and the direction is Wu; Chou Shan Weixiang means that the back of the house is Chou and the direction is Wei.
It is easy to distinguish the sitting direction of houses in rural areas, but it is more difficult to determine the sitting direction of high-rise buildings in modern cities without rich experience. Therefore, there is a situation of "each master has his own method" in determining the sitting direction. Strange phenomenon.
