The wall cabinet above the house door can only have three cabinet doors, not two. The reason why it cannot be installed is that Feng Shui believes that the gap between the two cabinet doors looks like a sword. Directly facing the center of the door. In Feng Shui, this is called "Heaven's Sword", and it is said to be detrimental to people who often go in and out of this door (at least it may cause health problems, and in more serious cases, their lives may be in danger). In addition, when buying a house, you cannot buy a house in another building with a narrow distance between two high-rise buildings and which is shorter than the two high-rise buildings (a building located in a "pin" shape, with the "mouth" above), which also belongs to The type of "Heavenly Sword".
