Use of geomantic compass when burying.

My family is a three-thirds system, that is, three points, three plates and three levels. The three points are the center of the tomb, the middle of the second tomb of the Li nationality and the top of the single tomb. The three points are different; Three sets are inner, middle and outer sets, which one do you think? The three levels are the layout of mountain pass, the correspondence of eight palaces, and the good and bad luck of geomantic omen in the twenty-four mountains, also known as pattern fault, palace divination fault and geography fault. Only by looking at three levels can we reflect the whole family. It is best to hold the bracket with an advanced compass when hanging in the field, otherwise the measurement will be inaccurate.
