Excuse me, what does the old evil spirit mean in the geomantic zodiac?

It is one of the three evil spirits. Three evil spirits refer to robbery, disaster and old evil spirits. From ancient times to the present, Yi-ology scholars and Feng Shui experts all believe that these three evils are very unfavorable to people, and they are the great evils in the fleeting time, so they will lead to unlucky fleeting time and bring all kinds of disasters and disadvantages, so they must be avoided. The three evils are fleeting and changing every year. We just need to solve them in advance. The door opens like a tiger's mouth. Master Poseidon summarized the experience of many examples of home feng shui. If the entrance or bedroom and office doors are opened in the third place, some unfavorable things will happen at home more or less. Because the door is the air intake of the family, just like the mouth of a person, it is auspicious and lucky for the family. If you accept Sha Qi, the people inside will fall into constant disasters.
