Set up the star map with copper coins, bury it in the ground according to the order of 88 stars, and shoot Kunlun on the ground according to the corresponding positions of the stars (regardless of size, shape and direction). Finally, draw a water on the map to represent the Milky Way (no matter how big or small, you can cross the map, but it must be above the map, preferably running water).
There must not be only auspicious stars on the astrolabe, otherwise there will be an imbalance between yin and yang.
After that, there are renovations, houses and so on. Will follow the direction of the star map in the star map, or if not, follow the original one.
