The five ghosts in Feng Shui do not mean that there are ghosts in this position. I don't know if I can catch ghosts by putting Zhong Kui on it. If this is correct, isn't it necessary to hang one in every household?
In geomantic omen, there are also people who put a glass of water in front of the property to strengthen their ability to make money, but at the same time put it on both sides in front of the idol. I don't seem to have heard of this method. On the contrary, there is an evil in Feng Shui called Lian Tears, that is, the two water sources in front of the door represent repeated disasters. Therefore, water will not be placed on both sides at the same time, and it is the same in front of the gods.
In any case, geomantic omen pays attention to orientation, direction and analysis combined with time. What matters is the orientation of the house, the orientation of the doors and windows and so on. If the orientation and spacing are good, there is no need to put anything at all, but when the house is inherently poor and cannot be changed, there is no other way but to put feng shui supplies to improve it. As for those lucky arrays, their influence is far less than the original pattern.
