Feng Shui is the study of orientation, and the orientation of the dead door is the most unlucky. The eight doors of Taoism: opening the door, the door of life, the door of divorce, the door of injury, the unique door, the door of scenery, the door of death, and the strange door, all have their own functions. One of the most taboo is the death clinic, which is a major problem of house feng shui. A bed is the longest place in a person's life. If it is a clinical death, it must be solved.
