1. In the feng shui decoration at the end of the corridor, red is the representative color of due south, symbolizing a person's name and fortune. Because the five elements due south belong to fire, if a mirror is placed at the end of the corridor due south, the volume of the mirror should not be too large. The reason is that the mirror belongs to water, which will put out the fire, which will be unfavorable to the owner's reputation and fortune.
2. The ends at both ends of the corridor cannot be zigzag. One is to waste the area of the house. Another reason is that it will form a trapped pattern. In addition, in the geomantic omen at the end of the corridor, the bathroom can't be placed at the end of the corridor, otherwise it will prevent the dirty air generated by the bathroom from spreading to the whole house.
