Determination and solution of Yangzhai orientation

Eight-house geomantic omen, a house has only one kind of divination, which is always seen from the sitting style of the house. According to the earthquake, Xun, Li, Kun, Dui, Gan, Kan and Gen, the house is divided into eight parts, namely east, southeast, south, southwest, west, northwest, north and northeast. For example, the front door of your house faces east and west, which is the earthquake house. Knowing the divination of Yang Zhai also needs to know the divination of the owner, which requires determining the owner's birthday. Kunmen means that you are standing in the center of the house, and your door is open in Kunmen, which is southwest. In other words, the Kunmen in Kanzhai is a house facing south, and the gate is open in the southwest. Starting from Zhaikongmen, take the south direction, the north gate and the southwest direction. Is that clear? Hope to adopt.
