How to orient the geomantic omen of Yangzhai under the compass

There are two ways to orientate the geomantic omen of Yangzhai under the compass: one is to measure the orientation of the built house. Take the door as the direction. When measuring indoors, choose a wall (there can be no interference from steel bars in the wall) and place the compass against the wall. Turn the disc on the compass so that the north-south line of the compass coincides with the north-south line at the bottom of Tianchi Lake. At this time, the twenty-four mountains pressed by the cross red silk thread (the line parallel to the wall) on the compass are all sitting. Second, build a house. For example, sit on the trunk and fork to build a house, and turn the disc on the compass to make a line on the cross red silk thread press on the trunk and fork. Put it on the chair and turn the whole compass so that the north-south line of the compass coincides with the north-south line at the bottom of Tianchi Lake. At this time, the dry red line is the sitting direction of the house.
