How to divide the orientation of residential feng shui?

As far as yangzhai is concerned, it can be divided into door and window. As the name implies, Menna is based on the orientation of the door, and Window Na is based on the orientation of the window. Different schools have different views. Personally, it is more reasonable for modern home ownership housing to be decided by the door. After all, people still go in and out through the gate. For example, to measure the orientation of a house, first measure the orientation of the gate, then measure it in the middle of the house and then measure it by the window. However, the current reinforced concrete structure will affect the accuracy of Luo Geng, so it is best to measure it downstairs (this can only be achieved by accumulating experience and having a strong sense of direction). ) haha ~ ~!
