The two emperors and three kings on the 23rd floor have no meaning, just a homophonic stalk. Buy a house and buy the five elements of Feng Shui on the 23rd floor, which is suitable for the owners of tiger, rabbit, snake and horse. This is the relationship between the geomantic floor and the five elements, and there are more floor selection skills.
